Sworn Translations: These are their Formal Requirements

1. Introduction

Checking the formal requirements of sworn translations is part of the day-to-day work of an immigration specialist. Although, in the vast majority of cases, sworn translators do an impeccable job in providing the documents with all the elements required by the applicable regulations, we must be aware that lawyers specialized in immigration law must act as guarantors of last resort.

The purpose of this article is to equip our followers with the necessary tools to be able to assess on their own whether a sworn translation has been properly carried out, at least in terms of its formal requirements.

2. Find a sworn translator.

First of all, we must make sure that the sworn translator is included in the official list of Sworn Translators of the Ministry of Foreign Affairs. Through the following link you can access the corresponding search tool:

Not all documents submitted to a file need to be accompanied by a sworn translation. However, if this is the case, it is important to make sure that you contact a professional who performs this type of translation.

3. Check the sworn translator’s identification and certification

A sworn translation may be certified on paper with a handwritten signature and physical seal, or electronically under the rules established by Order AUC/213/2025.

For a paper translation, check that the seal states the translator’s name, authorised language or languages, and registration number. The translation must also include the translator’s certification of its accuracy and their signature.

For an electronic translation, a text box containing those identification details replaces the physical seal. The qualified electronic signature must cover the complete file, including the document translated and the translation itself. An image of a signature or seal does not, by itself, replace a valid electronic signature.

4. Check the copy of the translated document

The translation must be accompanied by a copy of the document from which it was made. For a paper translation, that copy must be stamped and dated on every page. For an electronic translation, the specific electronic-signature rules apply to the complete file. Before submitting an electronic translation, check the receiving authority’s file-format requirements.

Do you need a certified translation of your documents? Do not hesitate to contact us. We work with experienced sworn translators who pay special attention to compliance with the formal requirements established by law.
