The carte grise: France's registration document and its one-month clock

Service-public.fr's used-vehicle fiche opens with the deadline: buy a vehicle — in France or abroad — and you have one month to request the new certificat d'immatriculation, filing online or via an authorised automotive professional. For a vehicle bought abroad, the same fiche warns that formalities must be checked before the registration request is filed — the customs and conformity layer our transfer-of-residence guide touches from the moving side.

The registration system itself (SIV) assigns the plate for the vehicle's life; the carte grise names the keeper rather than proving ownership — a nuance with real consequences at resale time.

A mover's vehicle imported with the household enters through the customs relief conditions, then meets the same one-month registration logic once resident; a car bought locally is simpler — dealer or private sale, then the fiche's clock. Either way the practical bottleneck is the digital file: ANTS accounts, the previous carte grise, proof of address — the same address that runs the rest of your French paperwork.

Insurance is compulsory from day one on French roads, and cross-border proof is the Green Card system's job — a separate instrument from the health cover your residence permit requires, which stays documented on the France hub.

The carte grise is one of three driving documents a settling foreigner juggles — with the licence exchange and motor insurance — and each runs its own clock. The moving checklist keeps them ordered with everything else:
