1. What is the correct term to use: certified translation, sworn translation, official translation, or something else?

Generally, the preferred term is “certified translation,” meaning a translation certified as true to the source document. You will also frequently encounter the term “sworn translation” which is also fine (although in French you should avoid the literal equivalent traduction jurée and opt instead for traduction certifiée). “Official translation” is also common, but is a bit more vague.

Also note that these terms do not necessarily carry the same meaning from one country/legal system to another, which makes it important to verify what is meant by “certified translation,” “sworn translation,” etc. in your specific context.

2. Who can issue certified translations?

In France, only experts traducteurs, i.e. translators listed as court experts with the Courts of Appeals or the Cour de cassation, are authorized to issue officially valid certified translations. The rules may vary for translations intended for use in a foreign country, but in general, a translation produced by a French expert traducteur will be recognized abroad. That said, some specific cases are subject to special rules. Feel free to contact me if you are unsure which requirements apply in your case.

3. What is the official title of the translator authorized to produce certified translations in France?

The official French term is expert traducteur, which reflects their status as an officer of the court and a court-appointed expert. In English, the terms “sworn translator” and “certified translator” are commonly used, but if your translation will be used in France, you should always check that your translator is an expert traducteur to ensure your translation will be accepted by the authorities.

4. Is it better to use a translation agency or a freelance translator?

Clients often turn to large agencies for their translations, mainly because those agencies have substantial marketing budgets and are therefore highly visible.

However, in France, only an expert traducteur registered with a Court of Appeal or the Cour de cassation can produce valid certified translations (see the answers above). As a result, since it is fairly difficult for agencies to employ such experts in-house, most translation agencies simply subcontract certified translation work.

To avoid the drawbacks of going through an intermediary—such as the inevitable sharing of your sensitive data—it is generally preferable to work directly with an individual certified translator whenever possible.

Finding one is simple: just consult the official list of court experts (for example, the 2026 Douai Court of Appeals list here—where you will find my name on page 348) under the specialty corresponding to your language pair; for example, for English translation, the relevant specialty is “H-02.02.01,” for Arabic, “H-02.03.02,” and so on.

You can access the lists for the various French Courts of Appeals here.

5. Do I need to choose a certified translator (expert traducteur) near me?

Not necessarily. Although it may seem a little counterintuitive, just because you are in Bordeaux does not mean your translator has to be from Gironde, nor does living in Paris mean they must be registered with the Paris Court of Appeal, etc.

French experts traducteurs have nationwide authority, which means you can choose a translator attached to any Court of Appeals in France.

However, whenever a physical original is needed—as is often the case for paper applications—it may sometimes be simpler and more reassuring to deliver the documents directly to the translator. This can be impractical (to say the least) if they are hundreds of kilometers away, which raises the issue of mailing costs and delivery times.

In short, if you only need a digital version of your translation, geography will not be an obstacle and you are free to choose whichever translator you wish.

If you need paper copies, however, geographic proximity may be a factor worth considering.

6. When do I need a certified translation?

For official or administrative matters (naturalization, marriage, residence permits, civil-status documents, driver’s licenses, etc.), a certified translation is almost always mandatory. This requirement is strictly enforced by the authorities, and applications are regularly rejected when no certified translation of non-French-language documents is provided.

The same applies in legal proceedings (service of process, service of a judgment, exhibits filed with a case, etc.) and in notarial matters (real-estate transactions, inheritance, etc.).

In addition, in the context of secondary or higher education, certified translations of diplomas, transcripts, and similar documents are also required by most institutions.

When in doubt, the safest bet is to ask the authority what type of translation is required; and if you are told that you need a “sworn,” “certified,” or similar translation (traduction certifiée, traduction assermentée, etc.), you will most likely need to contact an expert traducteur (see answer no. 1 above).

7. Why do authorities require certified translations in the first place?

Some people feel it natural to have their translations performed by a relative, machine translation software, or a third party whose qualifications are entirely unknown (a student? a non-professional translator? the applicant themselves…? who can tell, since the translator’s name is rarely even stated?). But in those cases, there is a genuine risk that the information contained in the document may be altered by the translator (lack of impartiality) or mistranslated (lack of competence).

That is precisely the role of the certified translator: to provide the recipient with every assurance that the text has been translated accurately, impartially, and in accordance with professional standards. The expert traducteur is an officer of the court whose qualifications have been vetted by the court as part of the applicatation process; they are bound by strict ethical rules, and and they affix their name and seal to the translation, thereby assuming full responsibility for it. As a result, the translation carries a strong presumption of accuracy, which is not the case with a non-certified translation.
