Spanish authorities ask for foreign birth certificates in translation for most procedures: nationality, immigration, marriage or Civil Registry entries. For UK and US certificates there is no shortcut — post-Brexit, no EU multilingual form applies — so the route is apostille first, sworn translation second.
One warning that saves real grief: many Spanish bodies require the certificate to be recently issued. Ask for the time limit before you order it back home.
It is probably the foreign document most often filed in Spain. Here is what you need to know to do it once and do it right.
Which procedures will ask for it
It comes up in nationality applications, immigration files, civil marriage, registering children, pensions and inheritance. Each body applies its own freshness requirement, so confirm that time limit before ordering: there is no point translating a certificate that will arrive at the counter already stale.
Not all certificates are equal: the version matters
This is where English-speaking countries trip people up. In the UK there is a full certificate (with parents’ details) and a short certificate; in the US, a long form and a short form or abstract. For Spanish procedures such as nationality, what is normally required is the full or long-form version, showing parentage.
Ordering the wrong version is one of the most expensive mistakes: it means requesting the certificate again from the GRO or the state vital records office, apostilling again and translating again. Confirm the exact version with the Spanish body before anything else.
Can you skip the translation?
For UK, US, Canadian or Australian certificates, realistically no. The multilingual aids that exist inside the EU — the Vienna Convention plurilingual extract and the EU multilingual standard form — do not apply: the UK left the EU and the US was never in that system. The standard route is apostille plus sworn translation.
Always the issuing country. For England, Wales, Scotland and Northern Ireland it is the FCDO; for US certificates, the Secretary of State of the issuing state; for Canada, the competent provincial or federal authority. Spain never apostilles foreign documents.
If your certificate comes from an EU country instead, ask the registry there for the multilingual standard form: it may spare you the translation, although the receiving authority can still request one if it considers it necessary.
The order: apostille first, translation second
When the certificate needs an apostille, it goes on the original document, in the issuing country. The sworn translation is done afterwards and reproduces the whole thing, apostille included. Translate first and apostille later, and the translation is incomplete — a routine ground for rejection.
You will find which countries apostille and which legalise in our guide to the Hague Apostille.
What the sworn translation includes
Everything: the certificate content, the apostille, stamps, seals, signatures (marked as illegible where they are) and any marginal notes on the reverse, which on birth certificates are frequent and often decisive: acknowledgements, adoptions, name changes. If the back has content and you don’t send it, the translation comes out incomplete.
Scan the whole certificate, flat, with all four edges visible and good light. If the reverse carries notes, scan that side too. A cropped photo or an unreadable seal means asking you for the document again — and delaying a procedure that usually has a deadline.
Frequently asked questions
Does a birth certificate expire?
The document itself carries no expiry date, but many Spanish bodies require it to have been issued recently. Confirm the time limit with the receiving body before ordering and translating.
Do I need the full certificate or is the short one enough?
For most Spanish procedures, the full (long-form) version showing parents’ details is the one required. Confirm with the receiving body before ordering — the short form is the usual cause of repeat requests.
Can I file the translation digitally?
Yes, where the receiving body accepts it. Sworn translations can be issued with the translator’s electronic signature and a growing number of Spanish administrations accept them online.
What if the certificate is in a less common language?
It can still be translated. If no sworn translator is appointed for that language, in certain cases a double sworn translation through a bridge language may be used. Each case needs assessing by language and receiving body.
