If you are going through an immigration procedure in Spain, you have probably run into a familiar problem: your documents are not in Spanish. Birth certificates, criminal records or academic qualifications usually need translating, but it is not always clear what type of translation you need or how to submit it correctly. In this guide you will see which requirements apply, when you need a sworn translation and how to avoid errors that can delay your procedure.
Which foreign documents need translating in Spain?

In general, any document issued in another language that has to be submitted to a Spanish authority must be accompanied by its translation into Spanish.
The most common documents include birth and marriage certificates, criminal records, academic qualifications, transcripts, notarial documents or employer certificates.
For example, if you apply for a residence permit or for Spanish citizenship, you will usually be asked for personal documents issued in your country of origin. In these cases, understanding the content is not enough: the document must meet formal requirements to be accepted.
When you need a sworn translation
One key point is to distinguish between a standard translation and a sworn translation.
A sworn translation is an official translation certified by a sworn translator. It is the one required in most administrative procedures, such as immigration, recognition of qualifications or court proceedings.
If you want to understand better what it involves and when it is required, you can read this guide on sworn translation in Spain and its most common uses.
What requirements must the translation meet
For a translation to be valid in an official procedure, it has to meet certain criteria.
It must be faithful to the original document and include every element, such as stamps, signatures or annotations. It must also follow the layout of the document.
In the case of a sworn translation, it must additionally carry the translator’s certification with signature and stamp.
Always submit the translation together with the original document or a valid copy. Submitting only the translation is a frequent mistake that can block the procedure.
Apostille, legalisation and the right order
Before translating, check whether the document needs an apostille or legalisation.
If the country of origin is a party to the Hague Convention, an apostille is used. If not, diplomatic legalisation is required.
The correct order is usually:
First obtain the document
Then have it apostilled or legalised
Finally have it translated
This order matters because the apostille must also appear in the translation.
Handling all these steps means juggling documents, copies, USB sticks and chargers at the same time. A travel organiser case for electronic accessories keeps everything in its place so you can take it to any appointment without leaving anything behind.
Common mistakes to avoid

Many immigration problems stem from formal errors in the documents.
One of the most common is using non-sworn translations where sworn ones are compulsory. Another frequent error is submitting incomplete translations that leave out stamps or annotations.
It is also common not to check the specific requirements of the procedure. Not all procedures ask for the same thing, and this can cause unnecessary delays.
If you are dealing with academic documents, it is especially important to get it right. In that respect, this guide on sworn translation for the recognition of qualifications in Spainmay help, as it explains the key points of that process.
Who can produce a valid translation
It depends on the use the document will be put to.
For official procedures, you usually need a sworn translator. For other uses, a professional translation may be enough.
In any case, it is advisable to work with professionals who specialise in legal documents, because this is not just about translating, but about meeting specific administrative requirements.
