Start by locating these records: Signed official form, photographs, identity evidence and proof of address; Civil-status records, marriage certificate and French transcription if the marriage occurred abroad; Evidence of marital cohabitation, the spouse's French nationality and language level. Keep unknown or unavailable details marked as such; a checklist is not proof that a document exists.

Check civil-status records, any required transcription and the competent channel before assembling the file. This fictional example demonstrates a preparation method, not the outcome of a real case.

Which mistakes can change the analysis?

Avoid these shortcuts: Presenting marriage as conferring nationality immediately without examining conditions and bars; Providing foreign civil-status records that are untranslated, unauthenticated where required, incomplete or internally inconsistent.
