Sworn translation in Spain: when you need one and the cost

When do Spanish authorities require a sworn translation?

A Spanish authority requires a sworn translation whenever you submit a foreign-language public document — for residency and NIE files, Spanish nationality, university admission or the homologation of a foreign qualification, court cases and civil-registry procedures. The rule is simple: a foreign language plus a Spanish official body equals a traducción jurada (per Ministerio de Inclusión guidance).

The reason a random translation will not do is that the sworn translator does something a bilingual friend cannot: they certify, with their signature and registered stamp, that the Spanish text says exactly what the original says. That certification is what gives the document legal weight in front of an official. Only a translator listed by the MAEC can add it, which is why the profession is tightly controlled under the Reglamento de la Oficina de Interpretación de Lenguas approved by Real Decreto 724/2020.

You almost certainly need one when:

• You are applying for residency, an NIE, a visa, or Spanish nationality using foreign birth, marriage or criminal-record certificates.
• You are enrolling at a Spanish university or asking the education ministry to recognise a foreign degree or school qualification.
• You are filing a foreign-language document in a Spanish court or before a notary.
• You are registering a foreign birth, marriage or death at the Spanish civil registry.

You may be able to skip it when:

• The document was already issued in Spanish (or in a co-official language the receiving body accepts).
• It is an EU civil-status certificate and you attach the free EU multilingual standard form (see below).
• The receiving body explicitly accepts a translation done by a Spanish consulate abroad or by the issuing country's diplomatic mission in Spain.

One trap catches people who arrive with paperwork from home: a translation sworn only in a non-EU country is not automatically valid here. If your document was translated by a certified translator in, say, the United States, a Spanish office can still reject it. The reliable routes are a MAEC-appointed translator working in Spain or a Spanish consular translation later legalised by the MAEC. Within the EU it is different — a sworn translation produced by a translator authorised under any member state's law must be accepted (EU Regulation 2016/1191).

What a sworn translation costs in Spain

Sworn translations in Spain are not state-regulated, so there is no official tariff and prices vary by provider, length and deadline. In 2026, English–Spanish work runs roughly €30–60 plus VAT per standard page of about 500 words, or €0.10–0.14 per word, and a single standardised certificate usually costs €40–85 (source: Spanish sworn-translation providers and price aggregators).

Because there is no fixed scale, the same birth certificate can cost noticeably more or less depending on who you ask and how fast you need it. The most-quoted unit is the standard page: for English, French or Italian into Spanish, expect about €30–60 plus VAT per roughly 500 words. Short, standardised documents are usually billed as a flat job rather than by the page.

Why is English among the cheaper pairs? Supply. Drawn from the MAEC official register, Spain had roughly 6,132 active sworn translators in mid-2024, and about 3,801 of them work with English across some 39 languages covered. Abundant competition for English keeps prices near the bottom of the range, while a rare language with a handful of registered translators can push past €0.20 per word.

Here is how the numbers add up in practice. Say you are applying for Spanish nationality by residence and need three foreign-language documents translated — a birth certificate, a marriage certificate and a home-country criminal-record certificate. At typical 2026 rates of €40–85 each, the three certificates come to roughly €150–210, and with VAT at 21% the final bill lands around €180–255. Knowing that before you order stops a single provider's rush surcharge from doubling it.

Getting the order right: apostille first, then the translation

The single most expensive mistake is ordering the sworn translation before the document has been apostilled. The apostille is part of the document, and it must itself be translated, so a translation produced before the apostille is stamped on is incomplete — the receiving office rejects it, and you pay a second time to have the now-apostilled document translated again.

The format question is newer, and it trips people up. Since Orden AUC/213/2025, in force since March 2025, a sworn translation can be certified with a qualified electronic signature under the EU eIDAS Regulation (910/2014) and delivered as a signed PDF that carries the same legal value as a stamped paper copy; the old mandatory physical stamp is replaced by a standardised text box showing the translator's name, languages and MAEC registration number.

In theory that means a PDF is enough anywhere in Spain. In practice, some administrative offices, notaries, courts and — especially — authorities outside the EU still distrust the electronic format and ask for a printed copy with a handwritten signature and stamp. The safe move costs nothing: before you order, ask the specific office that will receive the document which format it accepts, so you do not pay for a PDF you then have to reprint and re-certify.

One last timing point. A sworn translation does not expire on its own — no Spanish rule sets a shelf life, since the profession is governed by Real Decreto 724/2020 — so its validity tracks the original document. But many bodies still want the underlying certificate to be recent: a criminal-record certificate, for example, is often only accepted if issued within the last three months. If the original goes stale, the translation goes with it.
