Birth Certificate Translation

Your birth certificate is the most fundamental identity document you have, and in Portugal it comes up more often than you’d expect. Almost every interaction with the Portuguese state, from getting a residence permit to enrolling your child in school, requires a birth certificate. If yours isn’t in Portuguese, it needs a certified translation. If you have a Portuguese birth certificate and need it in English for UK authorities, I can help with that too.

Certified translation for Portugal (English to Portuguese)

I provide certified translations of birth certificates accepted by AIMA, the Conservatoria, and all Portuguese authorities. I handle the full process: translation, certification by a Portuguese lawyer, and delivery of a document ready for submission.

A certified translation of your birth certificate is required for more processes in Portugal than most expats realise. These are the situations my clients encounter most often:

Applying for a residence permit through AIMA. Your birth certificate is a core document in almost every residence permit application, whether you’re on a D7 visa, a digital nomad visa, a D2, D3, student visa, or applying through family reunification. AIMA requires a certified Portuguese translation of any document not already in Portuguese, English, French, or Spanish. Even if your birth certificate is in English and technically accepted without translation, many expats still choose to have it translated to avoid any ambiguity at the appointment. See the AIMA document checklist for a full breakdown of what you need. If you’d like someone with you at the appointment, I also offer an AIMA interpreter service.

Registering a birth in Portugal. When your child is born in Portugal and one or both parents are foreign nationals, you’ll need to provide your own birth certificates to the Conservatoria as part of your child’s birth registration. These must be translated and certified. My husband and I went through this process when our son was born. The Conservatoria needed both of our birth certificates translated, apostilled, and presented alongside the hospital’s birth declaration.

Registering a marriage in Portugal. Whether you’re getting married at the Conservatoria or transcribing a foreign marriage, both partners must provide full birth certificates issued within the last six months. If yours isn’t in Portuguese, it needs a certified translation. You may also need a marriage certificate translation if you’re transcribing an existing marriage.

Applying for Portuguese citizenship. Your birth certificate is required for naturalisation applications. It must be translated, certified, and accompanied by an apostille.

School enrolment for your children. When enrolling a child in a Portuguese school, whether public or private, you’ll need the child’s birth certificate. If it was issued abroad in a language other than Portuguese, the school will require a certified translation.

University applications and academic recognition. If you’re applying to a Portuguese university or seeking recognition of foreign qualifications through DGES, your birth certificate may be required as part of the application, translated and certified. You might also need your academic diplomas and transcripts translated.

NIF and tax registration. Getting your NIF (numero de identificacao fiscal) at Financas sometimes requires a birth certificate, particularly if you don’t yet have a residence card.

Social security (NISS) registration. Registering with Portuguese social security may require your birth certificate alongside other documentation, especially for family-related benefits.

Family reunification. If you’re bringing a child, parent, or sibling to Portugal through family reunification, the birth certificate is the primary document proving the family relationship. It must be translated and certified.

All translations are certified by a Portuguese lawyer, as required by Portuguese law. I review every document for accuracy before certification. For more detail on how this process works, see my guide on how certified translation works in Portugal.

Birth certificates vary significantly by country. A UK birth certificate from the General Register Office looks very different from an American birth certificate issued by a state vital records office, which looks different again from a Brazilian certidao de nascimento. Having trained as a lawyer in Brazil and lived in both Brazil and Portugal, I’m familiar with the format and terminology of certificates from all three, as well as the common formats from South Africa, Canada, Australia, and other countries. For country-specific guidance, see the page for British expats.

A birth certificate translation must faithfully reproduce every element of the original: full names (including middle names exactly as they appear), date and place of birth, parents’ names and details, registration numbers, the issuing authority, any stamps or seals, and any marginal notes or amendments.

Portuguese authorities are exacting about completeness. A translation that abbreviates a name, omits a registration number, or skips a marginal annotation can be rejected. I’ve seen cases where a birth certificate was sent back because an amendment note on the margin wasn’t included in the translation, even though the applicant thought it was irrelevant.

UK authorised translation (Portuguese to English)

If you’re a British national in Portugal and need a Portuguese birth certificate translated into English, I personally translate your Portuguese documents into English. I’m listed on the GOV.UK directory as an authorised translator for British nationals in Portugal, and my translations are officially recognised by the UK government.

You might need a Portuguese birth certificate translated into English for:

• HMRC – for tax matters, pension transfers, or proving dependant status.
• UK solicitors – for probate, property transactions, or family law proceedings.
• UK pension providers – when claiming a pension or updating records from Portugal.
• UK courts – for family court proceedings, custody matters, or other legal cases.
• UK visa and immigration – if a family member needs a Portuguese birth certificate translated for a UK visa application.
• Inheritance and estate matters – when a Portuguese-issued birth certificate is needed to prove a family relationship for UK estate purposes.

If your child was born in Portugal and you need their Portuguese birth certificate in English for any UK authority, this is the service you need. I handle this regularly for British expats living in Portugal.

Informal translation for personal understanding

Sometimes you just need to understand what a Portuguese birth certificate says, without any legal certification. Perhaps you’ve received a family member’s birth certificate from a Portuguese registry and want to know what’s on it, or you’re reviewing a document before deciding on next steps.

I can provide a straightforward English translation for your own reference. It won’t carry legal certification, but it gives you a clear, accurate understanding of the document. Get in touch and let me know what you need.

The apostille, and why order matters

If your birth certificate was issued in a country that’s part of the Hague Convention (which includes the UK, the US, Brazil, Australia, Canada, South Africa, and most of Europe), it will need an apostille from the country that issued it before the translation can be used officially in Portugal.

The most important thing to know about the apostille is the order: apostille first, then translation. The apostille is placed on the original document (or attached to it), and the certified translation must include the apostille text. If you get the translation done before the apostille, the translation won’t include the apostille, and you may need to have the document translated again.

This is one of the most common and expensive mistakes expats make. If your birth certificate doesn’t yet have an apostille, I can advise you on how to obtain one from your home country before we proceed with the translation. I’ve written a full guide to apostilles and legalisation that explains the process for different countries.

For UK birth certificates, the apostille is obtained from the Foreign, Commonwealth & Development Office (FCDO). For US certificates, it depends on the state. Some states apostille through the Secretary of State’s office, others through the state department. For Brazilian certidoes, the apostille is obtained from a cartorio autorizado.

What you need to provide

Send me a clear scan or photograph of your birth certificate. I can work from a digital copy. You don’t need to post the original. The document should be legible with all text, stamps, signatures, and any marginal notes visible.

If your birth certificate has an apostille already attached, include that in the scan too. The apostille needs to be translated as part of the certified translation.

For UK birth certificates: make sure you’re providing a full birth certificate, not a short-form extract. The full certificate includes parents’ details, which Portuguese authorities typically require.

Pricing and turnaround

A standard birth certificate translation including lawyer certification starts from €60. Most birth certificates are a single page and fall at or near this starting price. Certificates with additional pages of amendments, annotations, or an attached apostille may be slightly more. See the full pricing page for details.

For a GOV.UK authorised translation (Portuguese to English), pricing starts from €50.

Standard turnaround is 2 to 3 working days. Priority turnaround is available if you have an upcoming AIMA appointment or Conservatoria deadline. Let me know the date and I’ll confirm whether I can meet it.

If you need multiple documents translated for the same process, such as a birth certificate alongside a criminal record certificate and a marriage certificate for an AIMA application, ask about bundle pricing.

Why work with me

I’m Duda. I handle the entire document process so you don’t have to navigate it yourself. I tell you exactly what you need, coordinate the certified translation through a Portuguese lawyer (as required by Portuguese law), review everything for accuracy, and deliver a document ready for submission.

For British nationals, I’m listed on the GOV.UK directory as an authorised translator and interpreter. My Portuguese-to-English translations are officially recognised by the UK government.

I trained as a lawyer in Brazil, I work in compliance and anti-money laundering, and I’ve personally registered my son’s birth in Portugal. I know what Portuguese authorities expect because I’ve been through the process myself.

Frequently asked questions

Does my birth certificate need an apostille before translation? Yes, if you want to use it officially in Portugal. The apostille must be on the original document before the translation is done. If you translate first and apostille later, you’ll likely need a new translation that includes the apostille text.

My birth certificate is in English. Does it still need translating? Since January 2025, AIMA accepts documents in English, French, and Spanish without translation. However, the Conservatoria, schools, and other institutions may still require a Portuguese translation. If you’re using the certificate for anything beyond AIMA, a certified translation is the safest option.

I only have a short-form birth certificate. Is that enough? It depends on what you need it for. Portuguese authorities typically require a full birth certificate that includes parents’ details. If you only have a short-form extract, you’ll likely need to order a full certificate from your home country’s registry before having it translated.

How recent does my birth certificate need to be? For marriage registration, the Conservatoria typically requires a birth certificate issued within the last six months. For other processes (AIMA, school enrolment, citizenship), there’s generally no expiry requirement on birth certificates, but check with the specific institution.

Can you translate birth certificates from any country? I handle translations between English and Portuguese. If your birth certificate is in another language, I may be able to help depending on the language. Get in touch and I’ll let you know. I regularly handle certificates from the UK, the US, Brazil, South Africa, Canada, Australia, and other English and Portuguese-speaking countries.

Can I translate my own birth certificate? No. Under Portuguese law, the person for whom the document is intended, or their immediate family members, cannot act as the translator. The translation must be done by an independent professional.

What’s the difference between a certified translation and a GOV.UK authorised translation? A certified translation (English to Portuguese) is certified by a Portuguese lawyer and used for Portuguese authorities. A GOV.UK authorised translation (Portuguese to English) is one I produce personally as an authorised translator listed on the GOV.UK directory, and it’s recognised by UK government bodies, solicitors, and courts.
