Certified translation in Portugal:
what AIMA, IRN
and the courts accept

Portugal has no sworn translators. What AIMA, IRN, courts and universities accept is a certified translation: a professional translation that the translator declares faithful, on their honour and in person, before a lawyer, a solicitador (a regulated Portuguese legal professional) or a notary. We translate, certify and deliver, in Portugal or anywhere in the world, without you ever needing to be here.

What is a certified translation in Portugal?

A certified translation in Portugal is a professional translation with legal value: the translator declares, on their honour and in person before a lawyer, solicitador or notary, that the translation is faithful to the original, and that professional certifies the declaration.Portuguese law gives that certificate the same evidential force as a notarial act.(Decree-Law 237/2001, article 6; Decree-Law 76-A/2006, article 38)

Portugal has no state-appointed sworn translators. What Portuguese authorities accept is the certified translation.

Portugal has no sworn translators, unlike Spain, France, Germany or Brazil: what gives a translation legal value here is the certification, case by case. The words also mean different things in different countries. A UK or US 'certified translation' is usually a translator's signed statement, with no notary; a 'notarised translation' is the closest equivalent to what Portugal requires.

If someone abroad told you to get a 'sworn translation for Portugal', this certified translation is what they mean.

02

When do you need a certified translation for AIMA, IRN or a Portuguese court?

Three rules apply to almost every case. The apostille always comes from the country that issued the document. Documents from another EU country may need nothing at all. Documents in English, French or Spanish are often accepted without translation, but the receiving entity has the final word.

The documents we see most often, and what each Portuguese entity expects:

DOCUMENTWHO ASKS FOR ITAPOSTILLE?CERTIFIED TRANSLATION?
Birth, marriage and death certificatesAIMA (immigration), IRN (civil registry), notariesYes if issued outside the EU; no if from an EU countryYes, unless in English, French or Spanish (often waived; confirm). From an EU country, the multilingual standard form issued with the certificate normally replaces the translation
Criminal record certificateAIMA, IRN, professional bodies, employersYes (FBI, ACRO, RCMP and similar); EU citizens: no, if it is a certificate of no criminal record issued by your country of nationalityYes, unless in English, French or Spanish; valid for about three months in practice
Degrees, diplomas and transcriptsUniversities, DGES (degree recognition), professional bodiesAlmost always, EU includedYes, unless in English, French or Spanish; universities vary
Powers of attorney and contractsNotaries, banks, land registryYes, on the notarial act: a foreign notary certifies the signature (or draws up the deed) and that country apostilles it. Alternative with no apostille: sign it at a Portuguese consulate, which acts as a Portuguese notaryYes; bilingual originals avoid it
Company documents (good standing, articles, board resolutions)Commercial registry, banks, public tendersYes in practice, EU included: EU Regulation 2016/1191 does not cover company documents, so the registry normally asks for an apostille (or legalisation). Board resolutions and other private documents are apostilled after a notary certifies the signaturesUsually; the registry may accept English, French or Spanish if the registrar knows the language. Confirm with the registry before ordering
Court judgments (divorce, custody, debt)Court of Appeal (recognition), civil registryOutside the EU, yes; inside the EU, no: the EU regulations on judgments waive it (Regulation 1215/2012, article 61; Regulation 2019/1111, article 90)Yes for non-EU judgments; EU judgments come with a standard certificate and the court may still ask for a translation
Bank statements, tax returns, payslipsConsulates, AIMA, banksUsually noOnly if the entity insists; English is usually accepted
Medical reports and vaccination recordsSchools, insurers, courtsRarelyFor insurers and courts, yes

The Convention has been in force for Vietnam since 11 September 2026. Thailand does not join until 28 February 2027; until then, documents for Thailand still require consular legalisation. Taiwan is a special case: it is not a party to the Convention, and Portugal has no formal diplomatic relations with Taiwan, so legalisation does not follow the usual consular route. Talk to us before you start. These lists cover the destinations we are asked about most and are not exhaustive: if your country is in neither list, tell us and we will confirm.

      How does a certified translation work in Portugal?

      The original is apostilled in the issuing country. A SMARTIDIOM translator specialised in the field translates it, a second linguist revises it, and the translator declares it faithful before a lawyer, solicitador or notary, who certifies the declaration. You receive a signed PDF or the paper original by registered post, anywhere in the world.

      What the Hague Apostille looks like on a certified translation

      The apostille is a standard form, identical in every country of the Hague Convention, with ten numbered fields. Whoever issues it, from the FCDO in the UK to a Secretary of State in the US, it looks like this. The example below is a Portuguese one, issued by the Prosecutor General's Office (PGR) and stapled to a certified translation.

      Can I get a certified translation online, from outside Portugal?

      Yes, from anywhere in the world. Whether you receive a PDF or paper depends on the entity that receives the document.

      Yes. Everything runs from a legible scan. When the receiving entity accepts digital documents, you receive a PDF with a qualified electronic signature, valid across the EU under the eIDAS Regulation. When it requires paper, we send the original by registered post with acknowledgement of receipt to any country.

      DIGITAL, 100% ONLINE
      When the entity accepts a signed PDF

      A qualified electronic signature (eIDAS Regulation), with the same legal value as a handwritten one across the EU. Once certified, you receive the PDF within minutes: no paper, no post. Accepted by most universities, banks and employers; confirm with AIMA before ordering.

      ON PAPER
      When the entity requires the original

      Consulates, foreign courts and some registry offices require paper. We deliver by registered post with acknowledgement of receipt to any country, or you collect it in Leiria or Porto.

      EITHER WAY
      You never need to be here

      Translation, certification, the Portuguese apostille when needed and shipping: SMARTIDIOM handles everything remotely, wherever you are.

      06

      Does the apostille come before or after the translation?

      Many files are refused on timing, not on translation. Four rules keep you safe.

      Before. The apostille goes on the original, in the country that issued it, and only then is the document translated: we translate the document and the apostille together and the translation is certified in Portugal. An apostille on a photocopy or on a translation done abroad is routinely refused. See how the Hague Apostille works in Portugal.

      ORDER
      Apostille first, translation second

      The apostille goes on the original, in the issuing country, before anything is translated. We then translate the document and the apostille together, and certify the translation in Portugal.

      VALIDITY
      Criminal records expire fast

      Portuguese entities treat criminal record certificates as valid for about three months, and consulates set their own limit, often 90 days. Request them close to your appointment.

      ORIGINALS
      Apostilles go on originals, not photocopies

      An apostille only certifies the signature on the document it is attached to. On a notarised photocopy it proves the notary's signature, not the document, and most Portuguese entities will not accept it. Get a fresh original, or a certified copy from the issuing authority, when you cannot part with yours.

      LANGUAGE
      'Often waived' is not 'never needed'

      English, French and Spanish documents are frequently accepted without translation, but each entity, and sometimes each clerk, decides. Ask in writing; if they insist, we certify within days.

      07

      What changes depending on the country that issued your document?

      Only the first step. Countries in the Hague Convention issue an apostille (the FCDO in the UK, the Secretary of State or the US Department of State in the US); countries outside it use consular legalisation. EU civil-status certificates need neither. The translation and certification in Portugal are the same for everyone.

      UK

      United Kingdom, after Brexit

      Since 1 January 2021 the UK has been outside the EU rules, so UK documents need an apostille from the FCDO Legalisation Office (paper or e-Apostille): ACRO police certificates, birth and marriage certificates, degrees. Translation is best done and certified in Portugal; a translation certified in the UK would need its own apostille and may still be questioned. UK driving licences are exchanged at IMT without a test; IMT asks for a certificate of authenticity from the DVLA. AIMA usually waives translation of English documents; consulates and registry offices sometimes do not.
      US

      United States

      Two kinds of apostille, two offices. The FBI Identity History Summary is apostilled by the US Department of State (federal). State-issued documents, such as birth and marriage certificates, degrees and notarised powers of attorney, are apostilled by the Secretary of State of the issuing state. The most common mistake we see is a federal document sent to a state office. Everything is in English, so AIMA usually waives translation; we certify when an entity asks for it.
      CA

      Canada

      Canada joined the Apostille Convention on 11 January 2024. Apostilles are issued by Global Affairs Canada or by the provincial authorities of Ontario, Quebec, British Columbia, Alberta and Saskatchewan. RCMP checks are apostilled the same way. Documents from Quebec in French are usually accepted without translation.
      AU

      Australia, New Zealand, South Africa, India

      All four are in the Convention: DFAT, the Department of Internal Affairs, DIRCO and the Ministry of External Affairs issue the apostilles. Indian documents are often in English, so AIMA usually waives translation; degrees and transcripts for DGES or a university may still need it.
      BR

      Brazil

      Brazil joined the Convention in 2016 and apostilles are issued at notary offices (cartórios). Brazilian documents are already in Portuguese, so no translation is needed: only the apostille in Brazil. If you need a Portuguese document for Brazil, we obtain the Portuguese apostille. Our Portuguese page covers these cases in detail.
      AO

      Angola, Mozambique, Guinea-Bissau and Timor-Leste

      Outside the Convention. Documents go through consular legalisation: the local foreign ministry, then the Portuguese embassy or consulate in the country. Cape Verde and São Tomé and Príncipe are in the Convention and use the apostille. Documents from these countries are usually in Portuguese, so only the apostille or legalisation is needed, not a translation.
      EU

      European Union (27 member states)

      Under EU Regulation 2016/1191, birth, marriage, death, civil-status, residence and (for EU citizens, from their own country) criminal record certificates need no apostille in Portugal. If the registry issued the EU multilingual standard form with the certificate (you have to ask for it), public authorities do not require a translation as a rule (articles 6 and 7 of the Regulation), provided they consider its information sufficient. Degrees, powers of attorney and company documents still need an apostille and, unless they are in English, French or Spanish and the entity waives it, a certified translation. EU judgments need no apostille either (Regulations 1215/2012 and 2019/1111), only a translation if the court asks for one. Norway, Iceland, Liechtenstein, Switzerland and the UK are not covered by Regulation 2016/1191: their public documents need an apostille, even though they are close EU partners.
      OUTSIDE

      United Arab Emirates, Qatar, Kuwait, Egypt and Nigeria

      These five are outside the Convention: consular legalisation, with an extra step at their own foreign ministry in some cases.
      DATES

      Vietnam, Thailand, China, Hong Kong and Macau: what changed, and when

      The Convention has been in force for Vietnam since 11 September 2026. Thailand does not join until 28 February 2027; until then, documents for Thailand still require consular legalisation. China has issued apostilles since November 2023, through its Ministry of Foreign Affairs and authorised local offices. Hong Kong and Macau have issued apostilles for decades and are unaffected by the 2023 change.
      08

      Do you need a sworn translation for a Portuguese document going abroad?

      For Portuguese citizens moving abroad and residents leaving, the process runs the other way, and we handle all of it.

      Sometimes. The UK Home Office and USCIS accept a Portuguese certified translation with a translator's certificate of accuracy. Canada's IRCC requires a certified translator or, failing that, a sworn affidavit before a notary or commissioner of oaths, and our certification before a Portuguese lawyer or notary is built for that second route. Some countries prefer their own sworn translators for certain acts but accept a Portuguese certified translation with a PGR apostille for many others. We tell you which applies to your destination before you pay.

      APOSTILLE
      Issued in Portugal, by the PGR

      Portuguese certificates, criminal records, degrees and notarial deeds are apostilled by the Prosecutor General's Office or its regional offices. We obtain it for you, on the original and, when required, on the certified translation.

      CERTIFICATION
      The one your destination recognises

      The UK Home Office and USCIS accept lighter formats, such as a translator's certificate of accuracy. Canada's IRCC asks for a certified translator or a sworn affidavit. Spain, France, Germany and Italy may insist on their own sworn translators for some acts, and accept a Portuguese certified translation with an apostille for others. Brazil needs no translation at all: Portuguese documents travel with the apostille only. We tell you which applies.

      WITHIN THE EU
      Often nothing at all

      Portuguese civil-status certificates travel to other EU countries without an apostille, and IRN can issue multilingual certificates that need no translation. Confirm with the receiving entity before you pay for anything.

      09

      Certified translation, sworn translation, apostille or legalisation: what is the difference?

      Four terms that sound alike and mean four different things.

      WHAT IT ISWHO DOES ITWHEN YOU NEED IT
      Certified translationThe translator declares on their honour before a lawyer, solicitador or notary, in PortugalWhenever a document has to produce legal effects in another language. It is what works in Portugal
      Sworn translationA state-appointed translator with their own stampDoes not exist in Portugal. Only when an entity in another country demands it, and then we advise you on the route
      ApostilleThe Prosecutor General's Office (PGR) for Portuguese documents; the issuing country for foreign documentsWhen the document goes to, or comes from, a country of the Hague Convention

      Frequently asked questions

      Q1I've been told I need a 'sworn translator' in Portugal. Where do I find one?
      You don't, because Portugal has none. Countries such as Spain, France, Germany and Brazil appoint sworn translators whose stamp alone makes a translation official. In Portugal, what gives the translation legal value is the certification, case by case, before a lawyer, solicitador or notary (Decree-Law 237/2001, article 6; Decree-Law 76-A/2006, article 38; chapter 01). AIMA, IRN, courts, universities and notaries all accept this certified translation. If someone abroad asked you for a 'sworn translation for Portugal', this is what they mean. Read more in our article on sworn translators in Portugal.
      Q2My documents are in English. Do I still need a translation for AIMA or IRN?
      Often not, but never assume. The law (Civil Registry Code, article 49(8), which AIMA also applies) waives the translation of documents in English, French or Spanish when the official handling your file knows the language. In practice AIMA rarely asks; IRN registry offices (nationality, civil registry, marriage) vary, and some ask for a translation anyway. Universities and professional bodies often waive it too; ask first. Banks, employers and private schools decide for themselves. Our advice: ask the entity in writing, and if they insist, we certify the translation within days. Documents in any other language always need a certified translation.
      Q3Do I need an apostille, and where do I get it?
      An apostille (Hague Convention of 5 October 1961) is issued by the country that issued the document, never by the country where you will use it. A US birth certificate is apostilled in the US, a UK police certificate in the UK, an Indian degree in India. Portugal's Prosecutor General's Office (PGR) only apostilles Portuguese documents. You need one whenever a public document from outside the EU is going to a Portuguese authority such as AIMA, IRN, DGES, a court or a notary. Get it on the original first (see the timing rules in chapter 06); the translation itself is never apostilled for use in Portugal. Our guide The Hague Apostille in Portugal explains it step by step.
      Q4My document was issued in another EU country. Do I need anything at all?
      Possibly nothing. Under EU Regulation 2016/1191 (see the table in chapter 02), birth, marriage, death, civil-status and residence certificates from any EU member state need no apostille in Portugal, and neither does a criminal record certificate when it is a certificate of no criminal record of an EU citizen, issued by the country of nationality. If your registry issued the EU multilingual standard form with the certificate (you have to ask for it), public authorities do not require a translation as a rule (articles 6 and 7 of the Regulation), provided they consider its information sufficient. The rule does not cover degrees, powers of attorney or company documents: those still need an apostille and a certified translation, unless they are in English, French or Spanish and the entity waives it.
      Q5My country is not in the Apostille Convention. What then?
      The document goes through consular legalisation in your country: the local foreign ministry authenticates it, then the Portuguese embassy or consulate there legalises it. Only then does it come to Portugal for translation and certification. This applies to Angola, Mozambique, the United Arab Emirates, Qatar, Kuwait, Egypt and Nigeria, among others. The Convention has been in force for Vietnam since 11 September 2026. Thailand does not join until 28 February 2027; until then, documents for Thailand still require consular legalisation. Documents from Angola, Mozambique, Cape Verde, Guinea-Bissau and São Tomé and Príncipe are usually in Portuguese, so no translation is needed, only the apostille or legalisation.
      Q6I already have a translation certified in my country. Will Portugal accept it?
      Sometimes, and it is a gamble. A translation certified by the Portuguese consulate in your country is accepted. A translation by a foreign sworn translator is not on the list of certifiers Portuguese law recognises: entities may accept it if the translator's signature is itself apostilled, or may not. A UK or US 'certified translation', a translator's statement with no notary, is generally not accepted. The safe route, usually cheaper too: send us your translation. One of our translators checks it against the original, a reviser revises it, and we certify it here. You pay for the revision instead of the translation.
      Q7How long does it take, and how long is it valid?
      A one-page document, such as a birth certificate, takes about 5 to 7 working days from scan to certified translation; paper by post adds transit time. Degrees, judgments and articles of association take longer, simply because they are longer. The certified translation itself never expires. What expires is the underlying document: Portuguese entities treat criminal record certificates as valid for about three months, and consulates set their own limit, often 90 days. Get the apostille and translation close to your appointment, not months before. Tell us your deadline at the start: we prioritise translation, revision and certification; the apostille depends on the issuing authority.
      Q8Is a certified translation valid in a Portuguese court?
      Yes. The certified translation has the evidential force of a notarial act (Decree-Law 237/2001, article 6; Decree-Law 76-A/2006, article 38) and is accepted by courts, notaries, registries and official bodies in Portugal. Only where a court has well-founded doubts about a translation may it require a translation made by a notary or authenticated by a diplomatic or consular officer of the country concerned, or order one from a court-appointed expert (article 134(2) of the Civil Procedure Code). Foreign judgments from outside the EU need their own apostille or legalisation, and always a certified translation, before recognition.
      Q9How much does it cost, and what about VAT?
      The price is made up of simple parts, and you pay only the ones your case needs: translation per word, independent revision per word, certification per document, the Portuguese apostille per document when your Portuguese document goes abroad, and delivery if by post. Certification is per document, whether it has one page or fifty. VAT depends on where you are: private individuals in the EU, including anyone already living in Portugal, pay Portuguese VAT at 23%; businesses in another EU country with a valid VAT number pay no Portuguese VAT under the reverse-charge rule; private individuals and businesses outside the EU pay no Portuguese VAT (Portuguese VAT Code, article 6(11)). Your quote states the exact treatment before you commit.
      Q10I need more than one copy. Is that possible?
      Yes. Tell us how many copies you need when you request the quote. You pay for the translation once; for each extra copy you pay only the certification (and the Portuguese apostille, if the document is going abroad).
      Q11We're a law firm, relocation company or translation agency with recurring work. How do you handle that?
      That is most of what we do: agencies, law firms, relocation companies and HR departments send us documents every month, and we ship directly to their end client. You get an account with agreed rates, a dedicated project manager who knows your document types and destinations, agreed turnaround, one invoice per month with reverse-charge VAT where applicable, and an NDA. Book a 30-minute call and we set up the workflow; after that, you just send.
      Q12Which documents do I need translated for Portuguese residency or nationality?
      For a residence permit at AIMA: criminal record certificate, birth or marriage certificate, and any contract or proof of income not in English, French or Spanish. For nationality at IRN: birth certificate and criminal records from every country you have lived in. Documents from outside the EU are apostilled first; we then translate and certify them in Portugal.
