France sets its own requirements for foreign public documents (birth/marriage certificates, diplomas…) submitted to a consulate, préfecture, university or town hall. The requirement is the same whatever the country the document comes from — that country only provides the mechanism to authenticate its own paper (see, for a Nigerian document, ng/demarches/authenticate-documents).
France asks for two things:
1. Proof the document is genuine — apostille OR legalisation
- If the issuing country is a Hague Apostille Convention member, an apostille from that country is enough.
- If it is not a member, the document needs consular legalisation (authenticated in the origin country, then legalised by the French embassy/consulate there).
- Which applies depends on the origin country's status — check it, then follow that country's authenticate-documents guide for the exact chain.
2. A sworn French translation
Unless the receiving body explicitly accepts the original language, the document must be translated into French by a traducteur assermenté — a translator enrolled on a French Cour d'appel list. (The layout of the translation varies by translator; what matters is only that the translator is sworn.)
Practical notes
- Order matters: translating before the document is apostilled/legalised can mean redoing it — confirm the sequence the receiving body wants first.
- Original + copy: French authorities usually want the original plus a photocopy.
- Requirements vary by the specific authority (consulate, préfecture, university) — confirm with the one handling your file.
Pièges connus
- Assuming a plain photocopy or an English document is accepted (it usually isn't).
- Using a non-sworn translator (a regular/agency translation is rejected).
- Getting the translation done before legalisation, then having to redo it.
