Sworn translation , or certified translation , is a type of translation carried out by a certified expert-translator, sworn by a Court of Appeal or, under certain conditions, by a sworn translator by a TGI depending on the country of destination of the certified document.

Sworn translation concerns legal and legal documents; it is intended for administrations, calls for tenders, and may be necessary for obtaining visas, or for other procedures in the context of setting up abroad, for example.

The sworn expert-translator is a natural person registered on a list of legal experts drawn up by a special commission which sits, generally once a year, in the Courts of Appeals of France. The certified translator is registered on the CEDESA list drawn up by the Public Prosecutor of each High Court.

No one can claim to be a sworn expert-translator or a sworn translator; if he is not appointed to this function by the Commission of the Court of Appeal or by the Public Prosecutor. This translator, particularly competent in the legal field, has officially taken an oath and his certification is authentic before the French courts and administrations.
