Sworn translation services in Spain

Sworn translation services in Spain are required when a document in another language has to be submitted, with official validity, to a Spanish authority, court, university, notary, registry or administrative body. LinguaVox manages sworn translations produced by translators authorised by the Spanish Ministry of Foreign Affairs, European Union and Cooperation.

This page is written for international clients, foreign residents in Spain, companies handling Spanish procedures and anyone who needs to understand the Spanish sworn translation system without relying on a literal rendering of Spanish legal terminology.

What is a sworn translation in Spain?

In Spain, a sworn translation is signed and stamped by a sworn translator-interpreter appointed by the Spanish Ministry of Foreign Affairs, European Union and Cooperation. The translator's stamp and signature certify that the translation is faithful to the source document for official purposes.

The term should not be equated with certified translation in every market. In the United States or the United Kingdom, certification is normally handled differently. In Spain, the relevant figure is the sworn translator appointed by the Ministry.

This distinction matters for clients searching in English. A document described as a "certified translation" in another country may need a Spanish sworn translation if it will be submitted to a Spanish court, registry, university, notary or administrative body. Conversely, a Spanish sworn translation may not be the format required by an authority outside Spain.

Documents commonly translated

Common documents include birth, marriage and death certificates, police records, academic transcripts, university degrees, diplomas, powers of attorney, company deeds, contracts, court judgments, medical reports, tax certificates, passports, residence permits, adoption files and documents for nationality, immigration, employment or study procedures.

Companies also request sworn translations for tenders, corporate filings, bank documentation, public procurement, commercial registers, litigation, compliance procedures and documents issued by foreign suppliers or authorities.

The source document may come from any country. Examples include UK birth certificates for Spanish nationality procedures, US academic transcripts for a Spanish university, French company documents for a Spanish notary, German court decisions for litigation in Spain or Romanian civil registry documents for administrative procedures.

Delivery format and official use

The required delivery format depends on the authority receiving the document. Some procedures still require a paper version with an original signature and stamp; others may accept a digitally signed sworn translation. The safest approach is to confirm the requirement before ordering the translation.

If the document will be used outside Spain, a different form of certification, notarisation or legalisation may be required. The receiving country and institution should always be checked before deciding the workflow.

LinguaVox handles the translation, but it does not provide apostille or legalisation services directly. If the original document needs a Hague Apostille or another form of legalisation, that step is usually separate from the translation. In some cases the apostille should be obtained before translation, because it may also need to be translated.

Languages and availability

LinguaVox handles sworn translations between Spanish and the languages for which sworn translators have been appointed in Spain. English, French, German, Italian, Portuguese, Arabic, Chinese, Russian, Romanian, Ukrainian, Catalan, Galician and Basque are among the most common requests.

Availability depends on the language pair, document type, urgency and whether the work requires a paper version or digital delivery. Less frequent combinations may need more scheduling time, since the number of officially appointed sworn translators can be limited.

Accuracy, confidentiality and quote preparation

A sworn translation must preserve names, dates, stamps, institutional references, handwritten notes, signatures and administrative wording. Where the document contains legal, medical, financial or technical content, it should be assigned to a translator with relevant subject-matter experience.

To quote accurately, we need a complete, legible copy of the document. Price and delivery time depend on the language, length, format, urgency and document type. Poor scans, handwritten content or complex tables may require additional review.

What we check before starting

Before starting a sworn translation, it helps to confirm that the document is complete, legible and suitable for translation. Stamps, handwritten notes, apostilles, signatures and marginal annotations may need to be reflected in the translated document, and a sworn translator should not guess at unclear information.

The country of use matters as much as the language. A Brazilian certificate for Spain, a French diploma for a Spanish university or a German judgment for a Spanish procedure may carry different documentary requirements. Sworn translation resolves the official language requirement, but not necessarily every legalisation step.
