A sworn translation (traducción jurada) is an official translation done by a translator authorised by Spain's Ministry of Foreign Affairs (a traductor jurado), who stamps, signs and certifies it — giving it legal validity for official use in Spain. A certified translation, in the UK/US sense, is simply a translation accompanied by the translator's or agency's statement of accuracy — it has no special official status in Spain and is generally not accepted where a sworn translation is required. For Spanish visas, residency, property, court and most official submissions, you need a sworn translation, not a certified one. Using the wrong type is a common cause of rejected documents and delayed applications. Our sworn translations service arranges valid ones.
What a Sworn Translation Is
A sworn translation — traducción jurada in Spanish — is an official, legally valid translation produced by a traductor jurado: a translator who has been officially authorised and appointed by Spain's Ministry of Foreign Affairs (the Ministerio de Asuntos Exteriores) for a specific language pair. The sworn translator stamps and signs the translation, attaches a formal certification, and in doing so takes legal responsibility for its accuracy. The result is a document Spanish authorities recognise as an official, faithful rendering of the original.
That official status is the whole point. Because a sworn translator is государ — sorry, state-authorised — the translation carries weight a normal one doesn't: courts, immigration offices, the tax authority, notaries, universities and town halls accept it precisely because of the sworn translator's official appointment and certification. When a Spanish authority asks for a translation of a foreign document, it almost always means a sworn one. This is the standard required for the documents behind visas, residency, property and most official processes, which is exactly why it matters to get right. Our sworn translations service uses properly authorised traductores jurados.
What a Certified Translation Is
"Certified translation" is a term from the UK, US and other English-speaking countries, and it means something different. There, a certified translation is generally a translation accompanied by a signed statement from the translator or agency attesting that it's a complete and accurate rendering of the original. It's a perfectly legitimate product for many purposes in those countries — but the key point is that it relies on the translator's own certification, not on any official government appointment.
In Spain, that distinction is decisive. A certified translation in the UK/US sense generally has no special official status and is usually not accepted where Spanish authorities require a sworn translation, because it doesn't carry the official authorisation of a traductor jurado. This is the trap that catches people out: they arrange a "certified translation" at home, assume it'll be accepted in Spain, and find it's rejected. The words sound interchangeable, but for Spanish official purposes they are not — and assuming otherwise costs time and money.
Sworn vs Certified Side by Side
| Sworn (jurada) | Certified (UK/US sense) | |
|---|---|---|
| Done by | Translator authorised by Spain's Foreign Ministry | Any translator/agency |
| Certification | Official stamp, signature & declaration | Translator's own statement of accuracy |
| Official status in Spain | Legally valid, recognised by authorities | Generally none |
| Accepted for Spanish official use | Yes | Usually no |
| Typical use | Visas, residency, property, court, tax | Informal / some non-Spanish contexts |
| Legal responsibility | The sworn translator, officially | The translator, informally |
The headline: a sworn translation carries official Spanish recognition because of the translator's state authorisation; a certified translation does not. For anything official in Spain, sworn is the one you need.
Which Spain Requires
For the vast majority of official purposes in Spain, the answer is a sworn translation. When a Spanish consulate, immigration office (Extranjería or UGE), the tax authority, a notary, a court, a university or a town hall asks for a translation of a foreign-language document, they require it to be a traducción jurada done by a Spain-authorised sworn translator. A standard or "certified" translation will generally be rejected, regardless of how accurate it is, because it lacks the official status they require.
There's a small nuance worth knowing: a sworn translation done by a traductor jurado appointed in Spain is the gold standard and universally accepted. Translations sworn by officially-recognised translators in some other countries may sometimes be accepted, but this is inconsistent and risky to rely on — so the safe course, especially for visa and residency documents, is a sworn translation by a Spain-authorised translator. The cost of getting a document re-translated correctly, and the delay to your application, far outweigh any saving from a cheaper non-sworn option. When in doubt, default to sworn.
When an authority says "translated", it means sworn
For Spanish visas, residency, property, tax and court matters, "translated" almost always means a sworn (jurada) translation by a Spain-authorised translator. A UK/US "certified" translation is not a safe substitute, and assuming it is risks rejected documents and a delayed application.
Documents That Usually Need One
Sworn translations are required for the foreign documents behind most expat processes in Spain. Common examples include:
- Visa & residency documents — criminal record certificates, medical certificates, proof of income, and supporting papers for the Non-Lucrative, Digital Nomad and other visas.
- Civil documents — birth, marriage and divorce certificates, for family reunification, marriage in Spain, or school enrolment.
- Academic documents — degrees, diplomas and transcripts, for study, work or qualification recognition (homologación).
- Property & financial documents — certain documents in a purchase, mortgage or inheritance matter where a foreign-language original is involved.
- Court & legal documents — anything submitted in Spanish legal proceedings.
These documents typically also need to be apostilled first (see below), and the sworn translation usually covers the apostille too. Because the exact requirements vary by document, authority and your specific process, it's worth confirming what's needed before commissioning translations — getting it right first time avoids the classic delay of discovering, mid-application, that a document isn't in the accepted form. Our apostille and legalisation and sworn translations guides cover the detail.
Sworn Translation vs Apostille
These two are often confused, but they do different jobs and you frequently need both. An apostille is a certificate (under the Hague Convention) that authenticates the origin of a public document — it confirms that the signature, seal or stamp on the original is genuine, so the document is recognised internationally. It's obtained in the country that issued the document, before translation. A sworn translation, by contrast, renders the document (and usually the apostille) into Spanish with official legal validity.
So the typical sequence for a foreign document destined for Spanish official use is: (1) obtain the document, (2) get it apostilled in the issuing country, then (3) have it sworn-translated into Spanish by a Spain-authorised translator (the sworn translation covering both the document and the apostille). Skipping or reversing these — translating before apostilling, or apostilling but using a non-sworn translation — is a frequent cause of rejection. Getting the order and the type right is exactly the kind of detail that separates a smooth application from a stalled one, and it's part of what we handle. See our apostille and legalisation guide.
Common Mistakes
- Assuming "certified" equals "sworn". A UK/US certified translation generally isn't accepted in Spain where a sworn one is required.
- Arranging the translation at home. A translation by someone not authorised by Spain's Foreign Ministry usually won't qualify as sworn.
- Translating before apostilling. The apostille goes on the original first; the sworn translation then covers the document and apostille.
- Letting documents go stale. Some certificates have validity windows — getting them translated too early can mean they expire before submission.
- Choosing on price alone. A cheaper non-sworn translation that gets rejected costs far more in delay and re-translation.
- Not checking the specific requirement. Confirm what the particular authority needs before commissioning — requirements vary by document and process.

Frequently Asked Questions
A sworn translation (traducción jurada) is done by a translator officially authorised by Spain's Ministry of Foreign Affairs, who stamps and certifies it, giving it legal validity in Spain. A certified translation, in the UK/US sense, is just a translation with the translator's own statement of accuracy and has no special official status in Spain. For official Spanish use, you need a sworn translation.
Generally no, where a sworn translation is required. A UK/US "certified" translation relies on the translator's own certification, not on official authorisation by Spain's Foreign Ministry, so Spanish authorities usually reject it for visas, residency, property, tax and court matters. Arranging a sworn translation by a Spain-authorised translator is the safe course.
A traductor jurado is a sworn translator officially authorised and appointed by Spain's Ministry of Foreign Affairs for a specific language pair. They stamp, sign and certify their translations, taking legal responsibility for accuracy, which is what gives a sworn translation its official status and acceptance by Spanish authorities.
Typically the foreign documents behind visas and residency (criminal record and medical certificates, proof of income), civil documents (birth, marriage, divorce certificates), academic documents (degrees, transcripts), and certain property, financial and court documents. The exact requirement varies by document, authority and process, so it's worth confirming before commissioning translations.
Usually yes, and in that order. An apostille authenticates the original public document in the country that issued it; the sworn translation then renders the document (and the apostille) into Spanish with official validity. The typical sequence is: obtain the document, apostille it, then have it sworn-translated. Translating before apostilling is a common mistake.
A sworn translation by a translator authorised in Spain is the gold standard and universally accepted. Translations sworn by officially-recognised translators in some other countries may sometimes be accepted, but this is inconsistent and risky to rely on — especially for visa and residency documents. The safe course is a sworn translation by a Spain-authorised translator.
Your documents are likely to be rejected by the Spanish authority, delaying your application and meaning you have to commission a correct sworn translation anyway — often under time pressure. A cheaper non-sworn translation that gets rejected ends up costing far more in delay and re-translation, which is why defaulting to sworn for official purposes is the prudent choice.
Yes. We confirm exactly what each document needs for your specific process, arrange the apostille and a valid sworn translation by a Spain-authorised translator in the right sequence, and check everything before submission so nothing is rejected for being the wrong type or order.
