Brazilian Citizenship by Descent: Who Qualifies Through a Brazilian Parent — and Why Grandparents Do Not Count

Published September 30, 2026. Also available in Portuguese.

Brazilian citizenship by descent runs through a Brazilian father or mother, and it is not automatic. Under article 12, I, "c", of the Brazilian Constitution, in the wording of Constitutional Amendment 54 of 2007, a person born abroad to a Brazilian father or to a Brazilian mother is a Brazilian by birth on one of two conditions. The first door: the birth is registered with a competent Brazilian office — in practice, a Brazilian consulate. The second door: the person comes to live in Brazil and, after turning 18, opts for Brazilian nationality — which Decree 9,199 of 2017 places before a Federal Court, as a strictly personal act — no one can opt in your name. Neither door has a deadline in the text: the option is made "at any time" after majority, and the consulates I checked (Miami, Boston and Santiago, pages read September 30, 2026) register adults, who declare their own birth before two witnesses, free of charge. A grandparent does not count. The Constitution says "father or mother" and nothing else, and a federal appeals court — the TRF1, in case 1030523-26.2022.4.01.3400, judged on December 12, 2023, as reported by the court — ruled against the grandson of a Brazilian woman, who sought to be registered as the child of a Brazilian, because, in the words of the report, it could not be said that his father was Brazilian — holding that Brazilian law does not transmit nationality per saltum. So the parent in between must first become Brazilian through one of the two doors; on my reading, only then can the grandchild claim as the child of a Brazilian — and how a consulate treats a parent registered after the grandchild's birth is not settled in the pages I read. After a consular registration, the record is later transcribed at a registry office in Brazil so that it produces full effects there. And for people born abroad between June 7, 1994 and Amendment 54 of 2007, article 95 of the ADCT, added by the amendment, says they poderão ser registrados em repartição diplomática ou consular brasileira competente ou em ofício de registro, se vierem a residir na República Federativa do Brasil — “may be registered at a competent Brazilian diplomatic or consular office or at a registry office, if they come to reside” in Brazil (section 9).

The question reaches me in three versions. A Brazilian parent in the United States has a baby and wants to know what to do so that the child is Brazilian too. An adult born abroad — in Boston, Santiago or anywhere else — to a Brazilian mother or father was never registered and wants to know whether it is too late. And a grandchild of a Brazilian, often after reading about ancestry programs of other countries, wants to know whether a Brazilian grandparent is enough. The three questions have the same starting point, one line of the Constitution, and three different answers. This article reads the texts in force as I captured them on September 30, 2026, marks where a sentence is my reading rather than the text, and names no firm other than the author's.

Brazilian citizenship by descent in one answer

The table is the article in rows. The left column is who you are, the middle column is the door the texts open for you, and the right column is where it is written. Where a cell is my reading, it says so.

Two rows carry most of the traffic, and they are the two ends of the question. The first row is the everyday case: a Brazilian parent abroad registers a baby at the consulate, and the child is a Brazilian by birth. The last row is the case that most often ends in disappointment: a Brazilian grandparent, a parent who was never registered, and a grandchild who assumed that Brazilian citizenship by descent works like the ancestry programs of other countries. It does not. The rest of this article is the reasoning behind each row, provision by provision.

What Article 12, I, "c" says about citizenship by descent — and the one condition

Brazilian citizenship through parents is defined by the Constitution itself, not by an ordinary statute. Article 12 lists who is Brazilian by birth (brasileiro nato) and who is naturalized. The first three lines of the list, as the Planalto consolidation of the Constitution prints them, read:

Art. 12. São brasileiros: I - natos: a) os nascidos na República Federativa do Brasil, ainda que de pais estrangeiros, desde que estes não estejam a serviço de seu país; b) os nascidos no estrangeiro, de pai brasileiro ou mãe brasileira, desde que qualquer deles esteja a serviço da República Federativa do Brasil; c) os nascidos no estrangeiro de pai brasileiro ou de mãe brasileira, desde que sejam registrados em repartição brasileira competente ou venham a residir na República Federativa do Brasil e optem, em qualquer tempo, depois de atingida a maioridade, pela nacionalidade brasileira;

Article 12. The following are Brazilians: I – by birth: a) those born in the Federative Republic of Brazil, even of foreign parents, provided that these are not in the service of their country; b) those born abroad, of a Brazilian father or Brazilian mother, provided that either of them is in the service of the Federative Republic of Brazil; c) those born abroad of a Brazilian father or of a Brazilian mother, provided that they are registered with a competent Brazilian office or come to reside in the Federative Republic of Brazil and opt, at any time, after reaching majority, for Brazilian nationality;

Three features of that text decide everything that follows.

The first is who transmits. The text says pai brasileiro ou mãe brasileira — a Brazilian father or a Brazilian mother. Either parent is enough, and the text says nothing about the other parent's nationality. No other relative appears in the sentence: not a grandparent, not a great-grandparent. That is the whole textual basis of the answer about grandparents, which section 3 develops.

The second is the condition. Being the child of a Brazilian, born abroad, is not enough on its own; the text adds desde que — "provided that" — and then offers two alternatives joined by ou, "or". Door one: registrados em repartição brasileira competente, registered with a competent Brazilian office. Door two: venham a residir in Brazil e optem, come to live in Brazil and opt for Brazilian nationality — and that option comes depois de atingida a maioridade, after reaching majority, em qualquer tempo, at any time. The two doors are alternatives: the person who is registered does not need to move to Brazil or opt, and the person who moves and opts does not need a consular registration.

The third is what you get. The line sits under item I, natos. A person who walks through either door is a Brazilian by birth, not a naturalized Brazilian — the category the Constitution protects most, for example from extradition. Citizenship by descent in Brazil is therefore a citizenship of origin, recognized through a formality, not a grant made by the state at its discretion. A person born abroad with no Brazilian parent can become Brazilian only as a naturalized Brazilian (article 12, II) — a separate route; for the spouse of a Brazilian it is set out in the firm's article on marrying a Brazilian.

The wording of line "c" is not the original of 1988. It was given by Constitutional Amendment 54 of September 20, 2007, whose own summary says it was made assegurando o registro nos consulados de brasileiros nascidos no estrangeiro — securing consular registration for Brazilians born abroad. Section 9 comes back to why that phrase was needed.

Two neighbors of line "c" answer questions that often arrive with it. Line "a" is Brazil's jus soli: anyone born in Brazil is Brazilian by birth, even of foreign parents, unless the parents are in the service of their own country — so "does Brazil give citizenship by birth?" has a yes for births on Brazilian soil. Line "b" covers the child born abroad while a parent is in the service of Brazil — a diplomat, for instance — and asks for no registration and no option. Everything else in this article is line "c", Brazil's jus sanguinis: citizenship through a parent, on a condition.

The instrument. Before anything else, name the Brazilian parent and write down how that parent is Brazilian: born in Brazil, born abroad and registered, or naturalized. If you cannot fill that line with a document, you are not yet asking about your own citizenship — you are asking about your parent's, and section 3 is where to start.

Brazilian citizenship through grandparents? Parents, not grandparents — why a generation cannot be skipped

Can you get Brazilian citizenship through your grandparents? Not directly. The Constitution's line "c" speaks of the person born abroad de pai brasileiro ou de mãe brasileira — of a Brazilian father or mother — and nothing in article 12 extends that to grandparents. There is no separate "ancestry" procedure in the Brazilian texts I read, and no lineage test: the only question the text asks is whether your parent is Brazilian.

That question has been decided in a concrete case. In 2023 the 11th Panel of the Federal Regional Court of the 1st Region (TRF1), a federal appeals court, judged the appeal of a man who wanted to register his birth as the child of a Brazilian in order to obtain Brazilian nationality. His grandmother was Brazilian. His father had a consular registration made in Beirut and had held two Brazilian passports. The TRF1 published a news report of the judgment; the court's report of January 16, 2024 gives the case number, 1030523-26.2022.4.01.3400, and the date of judgment, December 12, 2023. As reported by the court:

Portanto, não havendo registro consular definitivo de nascimento do pai do impetrante, falecido em 2006, e não tendo ele optado pela nacionalidade brasileira na forma da Constituição, não há como afirmar que ele era brasileiro. E não sendo o genitor do impetrante brasileiro, “não há que se cogitar da transmissão da nacionalidade brasileira ao impetrante pelo critério jus sanguIni pelo fato de sua avó ser brasileira, pois o ordenamento jurídico pátrio não admite a transmissão da nacionalidade per saltum”, concluiu o juiz federal.

Therefore, there being no definitive consular birth registration of the petitioner's father, who died in 2006, and he not having opted for Brazilian nationality in the form of the Constitution, it cannot be said that he was Brazilian. And the petitioner's parent not being Brazilian, "there is no room to consider the transmission of Brazilian nationality to the petitioner by the jus sanguinis criterion because his grandmother is Brazilian, since the Brazilian legal order does not admit the transmission of nationality per saltum," the federal judge concluded.

The report adds that the panel decided unanimously, following the vote of the rapporteur, a federal judge sitting on the court. Per saltum means "by a leap": nationality does not jump over a generation. What I have read is the court's news report, not the judgment itself; I cite it as reported, with its number and date, and attribute to it nothing beyond what the report says. The report's spelling "sanguIni" is reproduced in the block as published.

Two details of the report explain why the father was not Brazilian, and both matter to anyone in a similar family. First, o registro consular do pai do impetrante tinha natureza provisória e foi efetivado em 1996 — the father's consular registration was provisional and was made in 1996, when, according to the report, he was already more than 36 years old. Second, the report says the rapporteur found that a Constituição, à época, exigia a residência no Brasil e a formalização da opção de nacionalidade para ser considerado brasileiro, na forma da anterior redação do art. 12, I, c. — the Constitution then in force required residence in Brazil and a formal option. The passports did not change that: as reported, the registration and the passports were not sufficient proof that he was Brazilian. He died in 2006 without having opted.

From this, the chain. A grandchild of a Brazilian is not, for that reason, anything under article 12. But the grandchild's parent — the child of the Brazilian grandparent — may well be covered by line "c": a person born abroad to a Brazilian parent. If that parent walks through one of the two doors — a consular registration, or residence in Brazil and the option in Federal Court — the parent is a Brazilian by birth; on my reading, the grandchild can then claim as the child of a Brazilian, under line "c" in their own name. That step is my reading, not a sentence of the texts: the reported case decided only the negative side — a father who could not be said to be Brazilian — and the pages I read do not say how a parent registered after the grandchild's birth is treated (below). Great-grandchildren would follow the same logic, one more link.

What if the parent in between has died without ever having been registered or having opted? The case above is that situation, and the court, as reported, found that it could not be said that the father was Brazilian and that the grandson therefore could not claim through the grandmother. My reading of the texts points the same way. The option for Brazilian nationality is, in the words of Decree 9,199, article 213, § 2, an ato personalíssimo — a strictly personal act — that takes place after majority; no one can opt in another person's name, and I found no provision, in the texts read for this article, that lets a descendant complete the option for a parent who has died. I do not say that no argument could ever be built; I say that the texts I read do not contain that route and that the one reported case went the other way.

When the parent is alive, the practical order is clear. The parent's case comes first. An adult child of a Brazilian who was never registered can, at the consulates I checked, register their own birth (section 5); the documents those consulates list for an adult's registration include the Brazilian parent's Brazilian certificates — and, at Miami and Santiago, the Brazilian death certificate where the Brazilian parent has died. Once the parent holds a Brazilian record, the grandchild's registration is a registration as the child of a Brazilian. One thing the pages I read do not settle is how a consulate treats a parent whose own registration was made after the grandchild was born; Santiago's list, for a naturalized Brazilian parent, asks for a certificado de naturalização anterior ao nascimento do registrando — a naturalization certificate predating the birth of the person being registered —, and says nothing about a parent who was Brazilian by birth but registered late. That is a question to put to the consulate before booking.

The instrument. Draw the family line from the Brazilian ancestor down to you and, for each person, write one word: registered, opted, or neither. The first person marked "neither" is where the work begins — and if that person has died, read the case above before spending money on anything else.

Registering a birth at a Brazilian consulate: who goes, who declares

How do you register a child born abroad at a Brazilian consulate? The federal services portal describes the service, "Registrar nascimento no exterior" (last modified December 15, 2025), in three sentences that frame the rest: consular posts may register the birth abroad of a child of a Brazilian father or mother; O registro somente poderá ser efetuado quando não houver registro anterior, lavrado em outra Repartição Consular brasileira ou em Cartório de Registro Civil no Brasil. — only if there is no earlier registration, at another consulate or at a registry office in Brazil; and Para obter o registro de nascimento, é obrigatório comparecer perante a Autoridade Consular. — attending in person before the consular authority is mandatory. On cost, the page is plain: Este serviço é gratuito para o cidadão.

The details are set by each consular post, and the portal itself sends you to the post of your interest. I read three: the Consulate General in Miami (page updated September 27, 2024), in Boston (updated July 6, 2026) and in Santiago (the page for adults, published October 20, 2025), all read on September 30, 2026. What follows is what those three pages say; other consulates publish their own pages, and I do not assume they are identical. Miami's page sets out who must attend by the age of the person being registered:

Se a pessoa a ser registrada tiver menos de 12 anos de idade, não é necessário que compareça ao Consulado-Geral; […] Se a pessoa a ser registrada tiver entre 12 e 16 anos, deve comparecer ao Consulado-Geral acompanhado do pai ou mãe brasileiro, bem como de duas testemunhas, que também assinarão o requerimento. O pai ou mãe brasileiro será o declarante; […] Se a pessoa a ser registrada tiver entre 16 e 18 anos incompletos, deve comparecer ao Consulado acompanhado do pai ou mãe brasileiro, bem como de duas testemunhas, que também assinarão o termo. O menor será o declarante; […] Se a pessoa a ser registrada tiver 18 anos completos ou mais, o registro de nascimento deverá ser feito pelo próprio interessado. Não é necessária, neste caso, a presença dos pais, mas sim de duas testemunhas, que também assinarão o termo de registro.

If the person to be registered is under 12 years of age, they do not need to attend the Consulate General; […] If the person to be registered is between 12 and 16, they must attend the Consulate General accompanied by the Brazilian father or mother, as well as two witnesses, who will also sign the application. The Brazilian father or mother will be the declarant; […] If the person to be registered is between 16 and 18 incomplete, they must attend the Consulate accompanied by the Brazilian father or mother, as well as two witnesses, who will also sign the record. The minor will be the declarant; […] If the person to be registered is 18 or older, the birth registration must be made by the person concerned. In this case the presence of the parents is not required, but that of two witnesses is, who will also sign the registration record.

Boston's page draws the same ladder in slightly different bands — 0 to 11, 12 to 17, and 18 or older —, with the 16- and 17-year-old as declarant, and adds a rule that matters to mixed couples: Caso um dos genitores seja estrangeiro, o declarante do nascimento deve ser sempre o genitor brasileiro. — where one parent is a foreigner, the declarant must always be the Brazilian parent. The federal service page provides for the case in which the Brazilian party cannot act: No caso de impedimento físico ou legal da parte brasileira, poderão figurar como declarantes todos aqueles indicados no art. 52 da Lei de Registros Públicos (Lei nº 6.015/73), independentemente da nacionalidade. — where the Brazilian party is physically or legally unable, the persons listed in article 52 of the Public Registries Law may declare, whatever their nationality. Set side by side:

On who may be a witness, the pages differ in a detail worth reading before the appointment: Miami asks for two witnesses maiores e capazes e brasileiras — adult, legally capable and Brazilian —, who may be relatives; Boston asks for witnesses who are adult and capable, de preferência brasileiras — preferably Brazilian. The pages also agree on the channel: in person, by appointment through the consular system; Miami states that Não existe a possibilidade de o registro consular ser solicitado por via postal ou por procuração, seja pública ou particular. — no registration by mail or by power of attorney.

Is consular registration free? At all three consulates I checked, yes. Miami: Custo: o registro consular de nascimento e a primeira via da certidão são gratuitos. — the registration and the first copy of the certificate are free. Boston: O registro de nascimento é um serviço gratuito. Santiago, on its adult page: Este serviço é gratuito. Other consular services, and later copies of the certificate, may carry fees; this article does not list them.

Two practical consequences come with the registration. Boston's page states that Quando a pessoa não possui CPF, o número é gerado durante o registro. — when the person has no CPF, the Brazilian taxpayer number, it is generated during the registration. And Miami's page ties the Brazilian passport to it: somente após efetuar o registro consular de nascimento, poderá ser concedido passaporte brasileiro em nome do registrado. — only after the consular registration can a Brazilian passport be issued in the registered person's name. The passport itself is a separate service, with its own requirements, which this article does not cover.

One more line on Boston's page deserves a mention because readers will see it. The page, updated July 6, 2026, opens with a message to the community about milhares de pedidos de registros feitos excepcionalmente nos últimos dias — thousands of registration requests made exceptionally in recent days — and warns that, because of that volume elevado e inédito de pedidos de registros, document checks and appointments may take additional time. The page does not say why the volume rose, and I do not speculate.

The instrument. Open the page of the consulate you intend to use and read it on the day — Boston's page accepts a birth certificate issued outside the United States once it is legalized or apostilled; Santiago's page for adults requires an apostille where the birth took place outside Chile —, and prepare four things before booking: the long-form foreign birth certificate, the Brazilian parent's Brazilian certificate and identity document, the other parent's documents, and — from age 12 — two witnesses who meet that consulate's rule. If the parents are married, register the marriage first: Boston's page recommends it, especially where a name changed, and Miami's so that the birth record carries the parents' married names.

Adults born abroad who were never registered

Can an adult be registered as Brazilian? Yes — that is what "at any time" means in practice. Nothing in line "c" sets an age limit for the registration door, and the three consulates I checked register people aged 18 or older. Santiago has a page for exactly this case, and its first sentence is the rule:

Nos registros de maiores de 18 anos, é dispensada a presença dos pais, e o declarante deverá ser o próprio registrando, que comparecerá ao Consulado, acompanhado de 2 testemunhas, para preencher e assinar o requerimento e o termo de registro de nascimento.

In registrations of persons over 18, the presence of the parents is waived, and the declarant must be the person being registered, who will attend the Consulate accompanied by 2 witnesses to fill in and sign the application and the birth registration record.

Miami says the same in its own words, as section 4 shows: the adult declares their own birth, the parents' presence is not required, and two witnesses sign. Boston lists, for 18 or older, only the adult, as declarant, and two witnesses. What the adult must bring, in the pages I read, is proof of their own birth — the foreign birth certificate — and proof that the parent is Brazilian. Santiago lists, as proof of the Brazilian parent's nationality, a Brazilian birth certificate issued in the last six months, a Brazilian marriage certificate that mentions the nationality, or a naturalization certificate predating the birth, plus a Brazilian identity document of that parent; and, among the additional documents, the certidão brasileira de óbito do pai ou mãe brasileiros, se falecidos. — the Brazilian death certificate of the Brazilian parent, if deceased. Miami's adult list likewise includes the certidão brasileira de óbito (se falecido).

That last item answers a question I hear often: "my Brazilian mother has died — is it too late for me?" On the pages I read, no. The adult's own registration rests on the fact that the mother or father was Brazilian, proved by Brazilian documents, and the consulates list a death certificate among those documents. This is different from the grandparent case of section 3, where the problem was that the father in between could not be said to be Brazilian.

Two points limit the adult route. First, the registration is available only if there is no earlier registration — the gov.br rule quoted above. An adult whose foreign certificate was already transcribed at a registry office in Brazil is in the situation of section 7, not this one. Second, the pages I read do not say whether a consulate registers someone who already lives in Brazil; for that person the texts provide the option (Decree 9,199, article 214; section 6), which on my reading is the natural door — ask the consulate before assuming either way.

The instrument. For an adult, the whole file is three proofs: your birth, your parent's Brazilian nationality, and two witnesses. Get the parent's Brazilian birth or marriage certificate first — issued recently if the consulate asks for it — because it is the document that most often has to be requested from a registry office in Brazil and takes the longest to arrive.

Already living in Brazil: the option for Brazilian nationality in Federal Court

The second door of line "c" is for the person born abroad to a Brazilian parent who comes to live in Brazil. It asks for two things, residence and the option, and the option is a judicial act. Decree 9,199 of 2017, which regulates the Migration Law, describes it in two articles:

Art. 213. A opção pela nacionalidade é o ato pelo qual o brasileiro nascido no exterior e que não tenha sido registrado em repartição consular confirma, perante a autoridade judiciária competente, a sua intenção de manter a nacionalidade brasileira. § 1º A opção de nacionalidade não importará a renúncia de outras nacionalidades. § 2º A opção de nacionalidade é ato personalíssimo e deverá ocorrer por meio de procedimento específico, de jurisdição voluntária, perante a Justiça Federal, a qualquer tempo, após atingida a maioridade civil. § 3º A União sempre será ouvida no processo de opção de nacionalidade por meio de citação dirigida à Advocacia-Geral da União, observado o disposto no art. 721 da Lei nº 13.105, de 16 de março de 2015 - Código de Processo Civil. Art. 214. O filho de pai ou de mãe brasileira nascido no exterior e que não tenha sido registrado em repartição consular poderá, a qualquer tempo, desde que esteja residindo no País, promover ação de opção de nacionalidade.

Article 213. The option for nationality is the act by which the Brazilian born abroad who has not been registered at a consular office confirms, before the competent judicial authority, their intention to keep Brazilian nationality. § 1. The option for nationality shall not entail the renunciation of other nationalities. § 2. The option for nationality is a strictly personal act and must take place through a specific procedure, of voluntary jurisdiction, before the Federal Courts, at any time, after reaching civil majority. § 3. The Union shall always be heard in the option procedure, through service of process addressed to the Office of the Attorney General of the Union, observing article 721 of Law 13,105 of March 16, 2015 – Code of Civil Procedure. Article 214. The child of a Brazilian father or mother born abroad who has not been registered at a consular office may, at any time, provided they are residing in the country, bring an action for the option of nationality.

Read piece by piece, the decree gives the option a precise shape. It is for the person not registered at a consulate — a registered person has already walked through the first door and does not need the second. It is filed in the Federal Courts, not at a registry office and not at the Ministry of Justice. It is a procedure of voluntary jurisdiction: there is no opposing party in the ordinary sense, but the Union is always heard, through the Office of the Attorney General of the Union (AGU). It is personalíssimo — no one can opt in another person's name. It comes after civil majority, at any time. And it requires the person to be residing in Brazil when the action is brought.

The Migration Law itself, Law 13,445 of 2017, has the same rule in fewer words, in its article 63: O filho de pai ou de mãe brasileiro nascido no exterior e que não tenha sido registrado em repartição consular poderá, a qualquer tempo, promover ação de opção de nacionalidade. The statute does not repeat the residence requirement; the Constitution does (venham a residir), and the decree spells it out.

Once the court grants the option, the proof is a registry entry. Article 216 of the decree provides that A comprovação da opção pela nacionalidade brasileira ocorrerá por meio do registro da sentença no Cartório de Registro Civil das Pessoas Naturais — the judgment is registered at the civil registry office —, and the Public Registries Law lists the options of nationality — as opções de nacionalidade — among the acts registered there (Law 6,015/1973, article 29, VII).

Two points follow from § 1 of article 213 and are worth stating plainly. The option does not ask you to renounce any other nationality: a US-born person who opts for Brazilian nationality in a Brazilian court does not, on Brazil's side, give up anything. And the option confirms a nationality the Constitution already describes as nato; it is not a naturalization, and it does not go through the naturalization rules of the Ministry of Justice.

What this article does not give is a timetable or a price. The decree does not fix one, the texts I read do not either, and the length of a federal proceeding depends on the court and the file. I make no forecast about the outcome of any option.

The instrument. If you already live in Brazil, the order is: proof of residence in Brazil, your foreign birth certificate (with its transcription, if one exists — section 7), proof that your parent is Brazilian, and a petition to the Federal Courts. If you do not live in Brazil and have no plan to, this door is not yours; the consulate is.

Transcribing a foreign birth certificate directly at a registry office — the weaker door

There is a third path in practice, and it is the one families sometimes take by accident: the foreign birth certificate of a child of a Brazilian is taken to Brazil and transcribed directly at a registry office, without any consular registration. The procedure is regulated by Resolution 155 of 2012 of the National Council of Justice (CNJ), in the compiled text I read, and its article 8 is the one that matters:

Art. 8º O traslado de assento estrangeiro de nascimento de brasileiro, que não tenha sido previamente registrado em repartição consular brasileira, deverá ser efetuado mediante a apresentação dos seguintes documentos: a) certidão do assento estrangeiro de nascimento, legalizada por autoridade consular brasileira e traduzida por tradutor público juramentado; […] d) documento que comprove a nacionalidade brasileira de um dos genitores. § 1º Deverá constar do assento e da respectiva certidão do traslado a seguinte observação: "Nos termos do artigo 12, inciso I, alínea "c", in fine, da Constituição Federal, a confirmação da nacionalidade brasileira depende de residência no Brasil e de opção, depois de atingida a maioridade, em qualquer tempo, pela nacionalidade brasileira, perante a Justiça Federal".

Article 8. The transcription of a foreign birth record of a Brazilian that has not previously been registered at a Brazilian consular office shall be made upon presentation of the following documents: a) the certificate of the foreign birth record, legalized by a Brazilian consular authority and translated by a sworn public translator; […] d) a document proving the Brazilian nationality of one of the parents. § 1. The record and its transcription certificate shall carry the following note: "Under article 12, item I, line "c", in fine, of the Federal Constitution, the confirmation of Brazilian nationality depends on residence in Brazil and on the option, after reaching majority, at any time, for Brazilian nationality, before the Federal Courts".

The omitted items are a declaration or proof of domicile — with the 1st Registry Office of the Federal District as the fallback where there is no domicile in Brazil — and an application signed by the person, a parent, a legal guardian or an attorney-in-fact. Item "a" speaks of legalization by the consulate; the same resolution, in article 2, § 3, tells registrars to observe agreements that waive legalization, and Miami's page, describing this route, speaks of an apostille and a sworn translation made in Brazil.

The note is the point. The transcription of a consular registration carries a note that the person is Brazilian by birth, with no condition attached (section 8). A child whose foreign certificate is transcribed directly is recorded with a condition: residence in Brazil and the option in Federal Court. The decree says what that condition does over time:

Art. 215. O filho de pai ou mãe brasileira nascido no exterior e cujo registro estrangeiro de nascimento tenha sido transcrito diretamente em cartório competente no País terá a confirmação da nacionalidade vinculada à opção pela nacionalidade brasileira e pela residência no território nacional. § 1º Depois de atingida a maioridade e até que se faça a opção pela nacionalidade brasileira, a condição de brasileiro nato ficará suspensa para todos os efeitos. § 2º Feita a opção pela nacionalidade brasileira, os efeitos da condição de brasileiro nato retroagem à data de nascimento do interessado.

Article 215. The child of a Brazilian father or mother born abroad whose foreign birth record has been transcribed directly at a competent registry office in the country shall have the confirmation of nationality tied to the option for Brazilian nationality and to residence in the national territory. § 1. After reaching majority and until the option for Brazilian nationality is made, the status of Brazilian by birth shall be suspended for all purposes. § 2. Once the option for Brazilian nationality is made, the effects of the status of Brazilian by birth go back to the date of birth of the person concerned.

So the direct transcription gives a child something real — Brazilian status until majority, on my reading of § 1, which suspends it only from majority onward — and then puts it on hold. From 18 until the option, the status of Brazilian by birth is suspended "for all purposes"; the option, in turn, requires residence in Brazil. When the option is made, § 2 is clear that its effects go back to the date of birth, so the person is treated as having been Brazilian all along. The Miami consulate's page describes the same route and the same note, and presents it as the path for when consular registration is not possible.

Why is this the weaker door for a family that lives abroad? Because the condition it attaches — residence in Brazil plus the option — is exactly the condition the consular registration does not have. A child born in Miami and registered at the consulate is Brazilian by birth and stays so at 18 wherever they live. A child born in Miami whose certificate was only transcribed in Brazil reaches 18 with the status suspended, and can only lift the suspension by moving to Brazil and going to court. For a family that intends to stay abroad, the consulate is, on my reading, the better door.

And if the direct transcription was already made? The consular registration is available only where there is no earlier registration — at another consulate or at a registry office in Brazil, in the gov.br wording. On that wording, a direct transcription already on file closes the consular door for the same person, which leaves the option; whether a registrar or a consulate would treat a particular earlier entry differently is a question for them, and I do not answer it here.

The instrument. Before carrying a foreign birth certificate to a registry office in Brazil, ask one question: does this child live abroad and intend to keep living abroad? If yes, register at the consulate first and transcribe the consular record afterwards (section 8). The order of the two steps decides which note goes on the certificate.

Taking the consular registration to Brazil: the transcription (traslado)

A consular registration makes the person Brazilian by birth, but it is a record kept abroad. To produce full effects in Brazil, it is transcribed (trasladado) at a registry office in Brazil. The rule is old and short, in article 32 of the Public Registries Law, Law 6,015 of 1973:

Art. 32. Os assentos de nascimento, óbito e de casamento de brasileiros em país estrangeiro serão considerados autênticos, nos termos da lei do lugar em que forem feitos, legalizadas as certidões pelos cônsules ou quando por estes tomados, nos termos do regulamento consular. § 1º Os assentos de que trata este artigo serão, porém, transladados nos cartórios de 1º Ofício do domicílio do registrado ou no 1º Ofício do Distrito Federal, em falta de domicílio conhecido, quando tiverem de produzir efeito no País, ou, antes, por meio de segunda via que os cônsules serão obrigados a remeter por intermédio do Ministério das Relações Exteriores.

Article 32. The birth, death and marriage records of Brazilians in a foreign country shall be considered authentic, under the law of the place where they were made, once the certificates are legalized by the consuls, or when taken by them, under the consular regulation. § 1. The records dealt with in this article shall, however, be transcribed at the 1st Registry Offices of the registered person's domicile or at the 1st Registry Office of the Federal District, where there is no known domicile, when they are to produce effect in the country, or, earlier, by means of a second copy that the consuls shall be obliged to send through the Ministry of Foreign Affairs.

Decree 9,199 says the same from the nationality side, in article 217: O registro consular de nascimento deverá ser trasladado em Cartório de Registro Civil das Pessoas Naturais para gerar efeitos plenos no território nacional — to produce full effects in Brazil. The CNJ resolution sets the procedure: the transcription is made at the 1st Registry Office of the domicile, or of the Federal District, sem a necessidade de autorização judicial — without a court order (article 1) —, on presentation of the consular certificate, a declaration or proof of domicile, and an application signed by the registered person, a parent, a legal guardian or an attorney-in-fact (article 7). And the record carries a note that is the opposite of the one in section 7, with no condition attached: Brasileiro nato, conforme os termos da alínea c do inciso I do art. 12, in limine, da Constituição Federal. — Brazilian by birth, under the first part of line "c".

When must it be done? The resolution answers in one line, article 9: O traslado de assento de nascimento ocorrido em país estrangeiro poderá ser requerido a qualquer tempo. — at any time. The consulates add practical advice. Boston's page says the transcription deve ser realizada, preferencialmente, na primeira oportunidade em que o registrado viaje ao Brasil ou no prazo de 180 dias a contar da data do retorno definitivo ao país — preferably at the first trip to Brazil or within 180 days of a permanent return. On my reading, that is a recommendation layered on a rule that sets no deadline: the word is preferencialmente, and the resolution says "at any time". Miami's and Boston's pages and the gov.br service all say that the consular certificate is to be transcribed afterwards in order to produce effects in Brazil.

Two details help. The CPF can be noted on the transcription free of charge: the resolution, in article 6-A, added in 2021, provides that Poderá ser averbado o número de CPF nos traslados dos assentos de nascimento, casamento e óbito de brasileiros em país estrangeiro, de forma gratuita. And errors in the consular record do not block the transcription: under article 5 of the resolution, the registrar transcribes and then corrects obvious errors, a point Miami's page repeats.

The instrument. Keep the consular birth certificate with the family's passports, and plan the transcription for the first trip to Brazil or the move there, at the 1st Registry Office of the city where you will live — or at the 1st Office of the Federal District if you have no domicile in Brazil. The application can be signed by the registered person, a parent, a legal guardian or an attorney-in-fact, and no court order is required; Miami's page describes the transcription as a simple procedure that does not depend on a court request.

Born between 1994 and 2007: the gap Amendment 54 closed

Line "c" in its current wording dates from 2007. The Planalto consolidation I read prints only that wording, so the text in force before it is described here only through what the 2007 texts and the court report say about it — and, on my reading, they point the same way: for births from June 7, 1994, the consular door had to be restored. The amendment's summary speaks of securing consular registration for Brazilians born abroad. The TRF1 report quoted in section 3 says the Constitution in force at the time required residence in Brazil and a formal option. And the amendment added a transitional provision, article 95 of the Temporary Constitutional Provisions Act (ADCT), for the people born in those years:

Art. 95. Os nascidos no estrangeiro entre 7 de junho de 1994 e a data da promulgação desta Emenda Constitucional, filhos de pai brasileiro ou mãe brasileira, poderão ser registrados em repartição diplomática ou consular brasileira competente ou em ofício de registro, se vierem a residir na República Federativa do Brasil.

Article 95. Those born abroad between June 7, 1994 and the date of promulgation of this Constitutional Amendment, children of a Brazilian father or Brazilian mother, may be registered at a competent Brazilian diplomatic or consular office or at a registry office, if they come to reside in the Federative Republic of Brazil.

The amendment is dated September 20, 2007, and the Planalto text refers to its publication in the Official Gazette of September 21, 2007. The window of article 95 is defined by the date of birth: born abroad between June 7, 1994 and 2007, to a Brazilian parent. Such a person "may be registered" at a consulate — or at a registry office, "if they come to reside" in Brazil. On my reading, the residence clause attaches to the registry-office alternative and not to the consulate, which is how the CNJ resolution treats consular records of that period, below; the text does not put the comma where it would settle the point, which is why I mark it as a reading.

Consular registrations made in those years could carry notes about residence in Brazil and the option, or be described as provisional — the CNJ resolution's own text shows it, because it orders those notes removed. It deals with them in its article 12:

Art. 12. Por força da redação atual da […] art. 95 do Ato das Disposições Constitucionais Transitórias (Emenda Constitucional nº 54, de 20 de setembro de 2007), o oficial de registro civil deverá, de ofício ou a requerimento do interessado/procurador, sem a necessidade de autorização judicial, efetuar averbação em traslado de assento consular de nascimento, cujo registro em repartição consular brasileira tenha sido lavrado entre 7 de junho de 1994 e 21 de setembro de 2007, em que se declara que o registrado é: "Brasileiro nato de acordo com o disposto no art. 12, inciso I, alínea "c", in limine, e do artigo 95 dos ADCTs da Constituição Federal." Parágrafo único. A averbação também deverá tornar sem efeito eventuais informações que indiquem a necessidade de residência no Brasil e a opção pela nacionalidade brasileira perante a Justiça Federal, ou ainda expressões que indiquem tratar-se de um registro provisório, que não mais deverão constar na respectiva certidão.

Article 12. By force of the current wording of […] article 95 of the Temporary Constitutional Provisions Act (Constitutional Amendment No. 54, of September 20, 2007), the civil registrar shall, of their own motion or at the request of the person concerned or their attorney, without the need for a court order, enter an annotation on the transcription of a consular birth record whose registration at a Brazilian consular office was made between June 7, 1994 and September 21, 2007, declaring that the registered person is: "Brazilian by birth under article 12, item I, line "c", first part, and article 95 of the ADCT of the Federal Constitution." Sole paragraph. The annotation shall also void any information indicating the need for residence in Brazil and for the option for Brazilian nationality before the Federal Courts, or any expressions indicating that the registration is provisional, which shall no longer appear on the certificate.

The omission marked […] is the resolution's reference to the current wording of line "c" — the page prints it as "alínea c do inciso I do art. 2", which, on my reading, means article 12. Note the two different date tests. Article 95 of the ADCT looks at when the person was born; article 12 of the resolution looks at when the consular record was made (lavrado), and the annotation it orders is made on the transcription of that record, by the registrar, without a court. The resolution presents the annotation as a consequence of article 95, and on my reading the two are meant to reach the same people — someone born in the window was necessarily registered in it or after it. The TRF1 case of section 3 shows why the distinction matters: the father there, as reported, had a consular registration made in 1996, inside the resolution's dates, but he had been born decades before 1994, and the court, as reported, treated that registration as provisional and found that it could not be said that he was Brazilian. A registration date inside the window is not, by itself, a birth date inside it.

The instrument. If you were born abroad between June 7, 1994 and September 2007 and hold a consular certificate that mentions residence, option or a "provisional" registration, take it with its transcription to the registry office and ask for the article 12 annotation; the resolution makes it a registrar's act, not a lawsuit. If you were born in that window and were never registered, the consular door is open to you like to anyone else under line "c".

Born in the US: birthright citizenship on one side, registration on the other

Many readers of this article are Brazilian parents in the United States, and their question has two halves. The American half was the subject of a Supreme Court decision this year. In Trump v. Barbara, No. 25-365, decided on June 30, 2026, the Court addressed Executive Order 14160, under which children born in the United States of parents unlawfully or temporarily present would not be citizens. The opinion of the Court answers:

No such intersovereign concerns apply to children born of parents unlawfully or temporarily present in the United States; no foreign sovereign would “have any motive for wishing” them outside this Nation’s authority. Ibid. Those children are thus subject to the jurisdiction of the United States. […] Under the Constitution, they are citizens at birth.

The Court affirmed the judgment of the District Court for the District of New Hampshire. For the purpose of this article, one sentence is enough: under that decision, a child born in the United States of parents unlawfully or temporarily present is an American citizen at birth, by birthright citizenship under the Fourteenth Amendment, which is the question the Court decided. I state nothing else about US law here.

The Brazilian half does not follow from the American one, and it is not automatic. Whether a US-born child is American is a matter of US law — for the children of parents unlawfully or temporarily present, the decision above answers it, and the opinion records that the rule it applied excluded the children of foreign ministers. The same child is Brazilian by birth only through line "c" — registered at a Brazilian consulate, or, later, living in Brazil and opting in Federal Court. Nothing on the Brazilian side asks the child to give up the American citizenship: the consular pages I read ask for no renunciation, and Decree 9,199 says of the option that it não importará a renúncia de outras nacionalidades. Whether a Brazilian who is also American can lose Brazilian nationality later is a different question, answered by article 12, § 4, and covered in the firm's article on Brazil dual citizenship.

The instrument. For a baby born in the United States, two documents matter, and they are made in two different places: the US birth certificate, issued under US law, and the Brazilian consular registration, made at a Brazilian consulate with the long-form certificate. The first records the American birth; only the second makes the child Brazilian.

The old four-year rule you may still read

Readers who search the Public Registries Law will find, in the same article 32 quoted in section 8, four paragraphs that describe a very different system. They are still printed in the Planalto text of Law 6,015, with no note of later wording on them:

§ 2° O filho de brasileiro ou brasileira, nascido no estrangeiro, e cujos pais não estejam ali a serviço do Brasil, desde que registrado em consulado brasileiro ou não registrado, venha a residir no território nacional antes de atingir a maioridade, poderá requerer, no juízo de seu domicílio, se registre, no livro "E" do 1º Ofício do Registro Civil, o termo de nascimento. § 3º Do termo e das respectivas certidões do nascimento registrado na forma do parágrafo antecedente constará que só valerão como prova de nacionalidade brasileira, até quatro (4) anos depois de atingida a maioridade. § 4º Dentro do prazo de quatro anos, depois de atingida a maioridade pelo interessado referido no § 2º deverá ele manifestar a sua opção pela nacionalidade brasileira perante o juízo federal. Deferido o pedido, proceder-se-á ao registro no livro "E" do Cartório do 1º Ofício do domicílio do optante. § 5º Não se verificando a hipótese prevista no parágrafo anterior, o oficial cancelará, de ofício, o registro provisório efetuado na forma do § 2º.

§ 2. The child of a Brazilian man or woman, born abroad, whose parents are not there in the service of Brazil, whether registered at a Brazilian consulate or not, who comes to reside in the national territory before reaching majority, may apply, before the court of their domicile, for the birth record to be entered in book "E" of the 1st Registry Office. § 3. The record and its birth certificates registered as in the preceding paragraph shall state that they are valid as proof of Brazilian nationality only until four (4) years after majority is reached. § 4. Within four years after reaching majority, the person referred to in § 2 must declare their option for Brazilian nationality before the federal court. Once the request is granted, the entry shall be made in book "E" of the 1st Registry Office of the domicile of the person opting. § 5. If the situation provided for in the preceding paragraph does not occur, the registrar shall cancel, of their own motion, the provisional registration made under § 2.

Read against the Constitution, these paragraphs — in a law of 1973, printed with no note of later wording — describe an older system: residence before majority, a provisional record, an option within four years of majority, and cancellation of the record if the option is not made. The Constitution in force says something else: the option is made em qualquer tempo, depois de atingida a maioridade — at any time after majority —, and the consular registration is a door of its own. On the four-year limit and on residence before majority, the Constitution prevails over these paragraphs, and the decree of 2017 follows the Constitution (a qualquer tempo, articles 213 and 214). The paragraphs are text still published, not the rule.

They are not only a curiosity. The TRF1 report of section 3 says the rapporteur found that the father não confirmou a nacionalidade até quatro anos após atingida a maioridade, nos termos do determinado à época pela Constituição Federal. — he did not confirm his nationality within four years of majority, as the Constitution then required. For people born long before 2007, the rules of their own time can still decide what their parents' records mean, which is why the date of each person's birth and each registration belongs on the family line of section 3.

How I handle a citizenship-by-descent question — and five mistakes

First the family line, with dates: who is the Brazilian parent, how that parent is Brazilian (born in Brazil, born abroad and registered, opted, naturalized — and when), and where and when the person asking was born. Then the records that exist: a consular registration, a direct transcription in Brazil, a court option, or nothing. Then the door: if there is no earlier record and the person can reach a consulate, the consular registration; if the person lives in Brazil and was never registered, the option in Federal Court, which on my reading is the natural door (the consular pages I read do not address residents of Brazil); if a direct transcription exists, the option, since on the gov.br wording the transcription already closes the consular door; if a consular record exists, its transcription in Brazil. For a grandchild, the same analysis is run first for the parent in between. When the file needs someone to act in Brazil, the power of attorney is a document of its own, and how the firm works with clients abroad — including how to verify the author's registration with the Brazilian bar — is in hiring a Brazilian lawyer from abroad.

Five mistakes we keep seeing.

1. Treating citizenship by descent as automatic. Being the child of a Brazilian abroad is not enough; line "c" asks for a registration or for residence and the option. Until one of them happens, the text's condition is not met.

2. Counting on a grandparent. The Constitution says "father or mother", and the TRF1, as reported, ruled against a grandson whose father, it found, could not be said to be Brazilian — Brazilian law does not transmit nationality per saltum. The parent in between has to become Brazilian first.

3. Transcribing the foreign certificate directly in Brazil when the family lives abroad. The direct transcription carries a condition — residence in Brazil and the option — and suspends the status from 18 until the option. For a family abroad, the consular registration avoids the condition.

4. Assuming it is too late at 18 or after a parent's death. The consulates I checked register adults, who declare for themselves with two witnesses, and list the Brazilian parent's death certificate among the documents. "At any time" is in the Constitution.

5. Relying on the four-year rule, or reading a registration date as a birth date. The four-year paragraphs of Law 6,015 are text of 1973, printed with no note of later wording; the Constitution prevails. And the window of article 95 of the ADCT is about when you were born; the CNJ annotation looks at when the record was made, and on my reading it does not stretch article 95 to earlier births.

The three facts that decide Brazilian citizenship by descent

Stripped to its skeleton, Brazilian citizenship by descent comes down to three facts:

• A person born abroad to a Brazilian father or mother is a Brazilian by birth on one of two conditions: registration with a competent Brazilian office — in practice, a consulate — or residence in Brazil and the option for Brazilian nationality, a personal act before a Federal Court after majority, at any time. Constitution, art. 12, I, "c", in the wording of Amendment 54/2007; Decree 9,199/2017, arts. 213 and 214.
• A grandparent does not transmit Brazilian nationality: the parent in between must first become Brazilian — and, on my reading, only then can the grandchild claim as the child of a Brazilian —, and the TRF1, as reported by the court, held that Brazilian law does not admit transmission "per saltum" (case 1030523-26.2022.4.01.3400, judged December 12, 2023). Constitution, art. 12, I, "c"; TRF1 news report of January 16, 2024.
• At the consulates I checked (Miami, Boston, Santiago; pages read September 30, 2026) the consular registration is free, and a person aged 18 or older declares their own birth before two witnesses (Miami and Boston also register minors); the consular record is later transcribed at a registry office in Brazil, at any time, as Brazilian by birth; and article 95 of the ADCT says those born abroad between June 7, 1994 and 2007 "may be registered at a competent Brazilian diplomatic or consular office or at a registry office, if they come to reside" in Brazil. gov.br service "Registrar nascimento no exterior"; Law 6,015/1973, art. 32, § 1; Decree 9,199/2017, art. 217; CNJ Resolution 155/2012, arts. 7, 9 and 12.

Carvalho Barros Advocacia Internacional handles these questions for Brazilians and families who live abroad — a Brazilian practice serving clients in more than 30 countries, with international family law counsel that reads, for each family, the sequence this article described: who the Brazilian parent is, which record exists, and which door the texts leave open today. Written communication with the firm is in English; meetings are conducted with an interpreter at no cost to the client. No promise of outcome is made or implied anywhere in this article.
