Apostille, Legalisation and Translation: Making a Foreign Document Usable in Portugal

Almost every Portuguese residence or civil-registry application depends on documents issued somewhere else: a birth certificate, a marriage certificate, a criminal record, a diploma. Before a Portuguese authority accepts one of them, it generally needs to be satisfied of two separate things — that the document really was issued by the authority whose name is on it, and that it can read it.

Those two things are handled by two different procedures, and they are constantly confused with each other. Authenticity is the apostille or consular legalisation. Readability is the translation. A document may need both, one, or neither. Guessing is expensive: a sworn translation and an apostille that were never required cost real money, and discovering at the counter that they were required costs weeks.

This chapter explains how to work out which of them your document actually needs, in what order to do them, and where each one is obtained. It also covers the situation that catches people most often, and which no official page explains: a document that looks foreign but is already Portuguese — in which case there is nothing to apostille, and no authority anywhere that could.

The two questions, kept apart

Before doing anything, answer these in order. Each one can end the process early.

• Is the document actually foreign? If it was issued by a Portuguese authority — including a Portuguese consulate abroad — it is a Portuguese document and needs no formality at all.
• If it is foreign, which country issued it? The answer decides whether you need nothing (European Union), an apostille (a country in the Hague Convention), or consular legalisation (everywhere else).
• What language is it in? This is a separate question with a separate answer, and it is decided by the language, not by the country.

The rest of this chapter works through those three questions in that order.

What an apostille is, and what it is not

An apostille is a certificate attached to a public document by an authority of the country that issued it, confirming that the signature on the document is genuine, that the person who signed held the office they claim, and that the seal or stamp is authentic.

It comes from the Hague Convention of 5 October 1961, which abolished the older, slower requirement of consular legalisation between the countries that joined it. As at 30 June 2026 the Convention has 130 contracting parties. Portugal has been one since 4 February 1969.

Two points about apostilles are misunderstood often enough to be worth stating plainly.

• An apostille says nothing about the contents of the document. It authenticates origin, signature, capacity and seal. It does not certify that the facts recorded are true, and it does not make an otherwise inadequate document acceptable.
• Only the issuing country can apostille its own documents. Portugal cannot apostille an Indian, Brazilian or American certificate, and neither can a Portuguese consulate. If your document was issued in Brazil, the apostille comes from Brazil, no matter where in the world you now live. This is the single most common wasted journey in the whole process.

First, check that the document is actually foreign

This section exists because of a case we were asked about, and because getting it wrong sends people looking for an apostille that cannot exist.

A Portuguese consulate abroad is a Portuguese civil registry office. When a consular post registers a birth, a marriage or a death concerning a Portuguese national, it draws up an assento — an entry in the Portuguese civil registry, which is then integrated into the national registry system. The resulting document is a Portuguese public document, issued abroad. Presented in Portugal, it needs no apostille, no legalisation and no translation, because it is not foreign and it is already in Portuguese.

This matters because the foreign certificate that the consulate used as its basis has already served its purpose. Once the marriage or birth has been transcribed into the Portuguese registry, that foreign document has no further role, and the question of apostilling it closed on the day of the transcription.

How to tell the two apart

Look at four things, in this order.

• The issuing authority named at the top. Consulado Geral de Portugal em …, or a Conservatória do Registo Civil in Portugal, or the Conservatória dos Registos Centrais in Lisbon, means the record is Portuguese. A foreign registry office, however Portuguese its name sounds, means the record is foreign.
• Who signed it. A Portuguese consular record is signed by the Consul or by a designated official of the post, often with the words por competência própria.
• The wording used for the record itself. A Portuguese entry is numbered as an assento of a given year, with a data do assento — the date the Portuguese registry made the entry, which is frequently many years after the event itself.
• The menções especiais. Where a Portuguese record was created from a foreign certificate, it usually says so: assento lavrado com base em certidão … emitida por …. That sentence is the proof that the transcription has already happened.

What does not settle it: the language, or the vocabulary. The words assento, teor, certidão, Livro n.º and Fls. are used by several foreign registries as well as by the Portuguese one.

Documents from former Portuguese territories

This is where judging a document by its language is least reliable, and it affects a large number of applicants.

Several countries and territories that were once administered by Portugal kept Portuguese registry vocabulary, Portuguese record formats, and in some cases Portuguese-era codes of law. Their offices may still be called Conservatória do Registo Civil and still issue certificates in Portuguese. They are nonetheless foreign states, and their documents are foreign public documents.

The clearest example is Goa, Damão and Diu, which have been Indian territory since 19 December 1961. A civil registry record made there since that date is an Indian public document. The Portuguese Consulate General in Goa states the position on its own civil-registration pages: Goan, Damanese and Diu marriages are evidenced by the Certificado de Registo de Casamento («Teor») issued by the competent Conservatória do Registo Civil, and — in its words — "Todos os documentos Indianos e as respetivas traduções, devem ser atestados com apostila pelo Ministério dos Negócios Estrangeiros da Índia." Note that the requirement extends to the translation as well as to the document.

The same logic applies to certificates from Angola, Mozambique, Cabo Verde, Guiné-Bissau, São Tomé e Príncipe, Timor-Leste and Macau. Being written in Portuguese removes the translation problem. It does not remove the authentication problem, which depends only on which state issued the document.

If the document is foreign: three routes, and only one applies

Route 1 — issued in the European Union: no apostille, no legalisation

Official Requirement. Under Regulation (EU) 2016/1191, applicable since 16 February 2019, a public document issued by the authorities of one EU member state and presented in another cannot be required to carry an apostille or any other authenticity stamp.

The Regulation covers documents whose purpose is to establish: birth; that a person is alive; death; name; marriage, including capacity to marry and marital status; divorce, legal separation and annulment; registered partnership, including capacity and status; dissolution of a registered partnership; parenthood; adoption; domicile and residence; nationality; absence of a criminal record; and the right to vote and stand in municipal and European Parliament elections.

Two further simplifications come with it. Authorities cannot demand the original and a certified copy at the same time. And multilingual standard forms exist for seven of those areas — birth, being alive, death, marriage, registered partnership, domicile or residence, and absence of a criminal record — which the issuing authority attaches to the document as a translation aid, removing the need for a sworn translation in most cases. Ask the issuing office for the multilingual form when you request the document; it is far cheaper than a translator, and many people do not know to ask.

What it does not cover. The Regulation is a closed list. Diplomas, academic transcripts, company documents, powers of attorney and medical records are outside it, and follow the ordinary rules.

Route 2 — issued in a country in the Hague Convention: an apostille

Official Requirement. The apostille must be issued by the authority designated for that purpose by the country where the document was issued, and by no one else. Each country designates its own; some use the foreign ministry, some the courts, and some, as in Brazil, delegate it to notarial offices.

The countries we are asked about most often are all contracting parties. The dates the Convention entered into force for each are: the United Kingdom (24 January 1965), the United States (15 October 1981), Ukraine (22 December 2003), India (14 July 2005), São Tomé e Príncipe (13 September 2008), Cabo Verde (13 February 2010), Brazil (14 August 2016), Pakistan (9 March 2023), China (7 November 2023), Canada (11 January 2024) and Bangladesh (30 March 2025).

Practical Advice. Several countries require a domestic attestation step before the apostille — a state or provincial authority certifies the document first, and only then does the national authority apostille it. In India, for example, the state Home or General Administration Department attests before the Ministry of External Affairs issues the apostille. Ask the designated authority what the sequence is in that country before you send anything, and remember that most of these authorities accept applications through agents, so you rarely have to travel.

Route 3 — issued outside the Convention: consular legalisation

Official Requirement. Where the issuing country is not a contracting party, the older procedure applies: the document is certified in a chain, typically by the issuing authority, then by that country's ministry of foreign affairs, and finally by the Portuguese consulate with jurisdiction over the place it was issued.

This matters a great deal for Portuguese-speaking applicants, because several of the countries whose nationals apply most often are not parties to the Convention. As at 30 June 2026, Angola, Mozambique, Guiné-Bissau and Timor-Leste are not contracting parties, while Cabo Verde and São Tomé e Príncipe are. If your document is Angolan or Mozambican, there is no apostille to obtain, and anyone who offers to get you one is mistaken. The route is consular legalisation.

Legalisation is slower than an apostille and involves more offices, so start it early.

What the law says, and what counters ask for

There is a genuine gap here, and you should know about both sides of it.

Official Requirement. Portuguese civil registry law is more permissive than most guidance suggests. Article 49.º/1 of the Código do Registo Civil provides: "Os documentos passados em país estrangeiro, em conformidade com a lei local, podem servir de base a actos de registo ou instruir processos independentemente de prévia legalização, desde que não haja dúvidas fundadas acerca da sua autenticidade." In other words, a foreign document drawn up in accordance with the law of the country that issued it can be used without prior legalisation, unless there is a founded doubt about whether it is authentic.

Observed Practice. Notwithstanding that provision, the published service guidance for registry procedures routinely states that documents from outside the EU must be legalised, with an apostille where the country is a Hague party, and counters commonly ask for it. Officials are entitled to raise a founded doubt, and an unauthenticated foreign document invites one.

Practical Advice. Do not plan your application around article 49.º/1. Obtain the apostille or legalisation if the ordinary rules point to it. The provision is worth knowing for a different reason: if you are refused solely because a document lacks an apostille, in circumstances where its authenticity is not actually in question — for example a document already accepted in an earlier procedure — it is the provision to raise, in writing, when asking for the decision to be reconsidered.

Translation

Official Requirement. Article 49.º/8 of the Código do Registo Civil provides: "Os documentos referidos no n.º 1, quando escritos em língua estrangeira, devem ser acompanhados de tradução feita ou certificada nos termos previstos na lei, salvo se estiverem redigidos em língua inglesa, francesa ou espanhola e o funcionário competente dominar essa língua."

Read the exemption carefully, because it has a condition attached. A document in English, French or Spanish is exempt from translation provided the official dealing with it is fluent in that language. For immigration files, AIMA states the exemption without the qualifier on its own document-recognition page: documents presented in English, French and Spanish do not need translation. At a registry counter, the qualifier is part of the rule, so an official may still ask.

Practical Advice. If your document is in English, French or Spanish, do not commission a translation before you have to. Present it as it is, and obtain a translation only if the office asks for one. If it is in any other language, it needs a translation, and there is no benefit in delaying.

Who may certify a translation in Portugal. A translation must be certified by a notary, a lawyer, a solicitador, or a Portuguese consulate. A translation done by a translator without one of those certifications is not sufficient for registry submissions.

The order of operations

Sequence errors are the most common avoidable cost in this whole area. Do it in this order.

• Obtain the document itself, in the fullest form available. Where a full-form certificate exists, ask for it: a short-form extract may not contain the detail the authority needs.
• Check its age. A certificate proves the state of a record on the day it was issued, not today. An old certificate cannot show anything recorded since. Obtain a recent one.
• Apostille or legalise it, if either route applies, from the authority in the issuing country.
• Then translate, if translation is needed — and translate the apostille as well as the document. The apostille is itself a foreign-language page with stamps on it, and having to go back to the translator for it is a common second trip.
• Then submit.

Translating before apostilling means the apostille is not covered by the translation. It is a small mistake that costs a second fee and another wait.

Apostilling a Portuguese document for use abroad

The reverse direction is simpler, and it is worth knowing because many applications require it.

Official Requirement. In Portugal the apostille is issued by the Procurador-Geral da República, under article 2.º/1 of Decreto-Lei n.º 86/2009, with the competence exercised by delegation through the regional offices. Requests are handled at Lisboa, Porto, Coimbra, Guimarães, Évora, Funchal and Ponta Delgada.

The documents that can be apostilled are public ones: acts of ministries, courts, conservatórias dos registos and cartórios notariais, public educational establishments, câmaras municipais and juntas de freguesia.

The fee is one tenth of the unidade de conta, currently €10.20, with a waiver on proof of insufficient means. Where the Portuguese document was drawn up in electronic form, the apostille is issued electronically too, and is requested online at apostila.ministeriopublico.pt rather than in person.

Transcription: the step that ends the problem permanently

If you or your spouse is a Portuguese national, there is a step that removes the authentication question for good, and it is the one most people do not know exists.

A birth, marriage or death that happened abroad and concerns a Portuguese citizen can be transcribed into the Portuguese civil registry. Article 6.º of the Código do Registo Civil is the provision that allows registry acts drawn up abroad by the competent foreign authorities to enter the national registry, and article 53.º governs entries made by transcription.

You need the foreign certificate, properly apostilled or legalised, once — for the transcription itself. From that point on the event exists as a Portuguese assento, and any certificate of it that you subsequently obtain is a domestic Portuguese document that needs no apostille, no legalisation and no translation, permanently.

Where it is done. The request can be made at a Portuguese consular post in the country where you live, or at a conservatória do registo civil in Portugal. Facts concerning Portuguese citizens that occur abroad are integrated centrally at the Conservatória dos Registos Centrais in Lisbon. There is no deadline: the transcription can be requested at any time after the event.

Practical Advice. If you are going to need to prove a foreign marriage or birth to Portuguese authorities more than once — and in an immigration process that spans an initial application, renewals, and possibly a nationality application later, you will — transcription is almost always worth doing early. It converts a recurring problem into a single one. It also settles the recognition of the event under Portuguese law, rather than leaving it to be assessed each time.

A fee applies to the transcription. We were unable to confirm the current amount from an official source when this chapter was last verified, so ask the conservatória or consular post for the current figure rather than relying on the numbers circulating online.

Common mistakes

• Trying to apostille a foreign document in Portugal. Only the issuing country can do it. A Portuguese consulate cannot apostille the document of the country it is posted in; it can only legalise it where the Convention does not apply.
• Buying an apostille for an EU document. Documents from EU member states covering the listed matters need none.
• Paying for a translation of an English, French or Spanish document before checking.
• Translating before apostilling, so the apostille itself is left untranslated.
• Looking for an apostille for an Angolan or Mozambican document. Those countries are not in the Convention; the route is consular legalisation.
• Presenting a certificate that is years old. It proves the record as it stood then, not now.
• Assuming a document in Portuguese is a Portuguese document. Check the issuing authority, not the language.
