Since the complete digitization of registration procedures, the declaration of vehicle transfer is done exclusively online. There is no longer a need to go through the prefecture. The entire process relies on the ANTS website or authorized platforms, with a legal deadline to respect and specific documents to gather before connecting.
Legal deadline and penalty: what the Highway Code provides for vehicle transfer
Article R.322-4 of the Highway Code, in its version in force as of June 16, 2025, requires the former owner to declare the transfer within 15 days of the sale or donation. This deadline starts from the date indicated on the transfer certificate, not from the handover of keys or payment.
Failure to comply with this deadline constitutes a 4th class offense. The fixed fine amounts to 135 euros. In practice, the main risk is not the fine itself, but the fact that the vehicle remains associated with your name in the registration file. Any offense committed by the buyer (parking, speeding, unpaid tolls) will be addressed to you as long as the transfer is not recorded.
This point remains underestimated. Feedback published on forums in 2026 describes situations where former owners receive fines several months after the sale, due to not having finalized the vehicle transfer declaration on Autoscope or on the ANTS website in time.
ANTS transfer code: useful but not legally mandatory
At the end of the online procedure on the ANTS website, the system generates a transfer code, composed of numbers and letters. This code must be transmitted to the buyer so they can initiate their own online registration request.
Updated content from September 2026 provides a rarely mentioned clarification: the transfer code is not a legal condition for the validity of the transfer. The buyer can theoretically register the vehicle with just the paper transfer certificate (Cerfa 15776*02). The procedure will be longer and more tedious, but it remains possible.
However, the absence of this code regularly causes blockages on the ANTS platform. The buyer finds themselves unable to finalize their online request, leading to email exchanges, support calls, and sometimes resorting to a licensed professional to unblock the file. Therefore, transmitting the code remains the best way to secure the transaction for both parties.
Documents to gather before launching the online transfer declaration
The process often stalls within the first few minutes because a document is missing. Before logging onto the ANTS website, ensure you have all of the following documents:
- The transfer certificate Cerfa 15776*02, completed and signed by both parties (seller and buyer), with the exact date and time of the transaction.
- The original vehicle registration document, crossed out diagonally with the mention “Sold on” or “Transferred on” followed by the date, time, and your signature.
- The administrative situation certificate (formerly non-pledge certificate), downloadable for free from the Histovec website.
- A proof of technical inspection less than six months old for vehicles over four years old (except vehicles sold for destruction).
The confidential code linked to the registration document is necessary if a third party is completing the process on your behalf. This code appears on the letter received when the registration document was issued. If you have lost it, a request for resending is possible on the ANTS website, but it takes several days.
Common mistakes on the ANTS platform and how to avoid them
The ANTS platform works, but it is not free from malfunctions. Testimonials collected on specialized forums in 2026 point out several sources of recurring blockages.
The most common issue concerns the inconsistency between the entered information and that in the SIV file (Vehicle Registration System). A simple character error in the registration number, or a date of birth that does not match the registered holder, is enough to have the file rejected without an explicit error message.
Another friction point: logging in via FranceConnect. The process requires authentication through this means. If your FranceConnect account is not up to date or if the identity linked differs from that on the registration document (name change, civil status error), the procedure is interrupted. Resolution then involves updating your digital identity with the identity provider used (impots.gouv.fr, Ameli, La Poste).
- Check that your registration number is in the correct SIV format (two letters, three digits, two letters) before starting the entry.
- Compare the information on your registration document with that on your FranceConnect account, particularly the birth name.
- Keep a screenshot of the transfer code generated at the end of the procedure, as ANTS does not automatically send this code by email.
Crossed-out registration document: the handwritten mention that protects the seller
Crossing out the registration document is not a symbolic gesture. The handwritten mention “Sold on” or “Transferred on” with the date, time, and signature serves as proof in case of dispute. If the buyer commits an offense between the time of sale and the recording of the transfer, this crossed-out registration document allows contesting the fines received.
The registration document handed over to the buyer must be complete. If it has a detachable coupon, it remains attached. Only the main part is crossed out, not the coupon. The buyer will need it to drive legally during the period of obtaining their new registration document.
The online transfer declaration remains a quick formality when the documents are ready and the information verified in advance. The real trap is not the complexity of the process, but the delay: each day of delay keeps the vehicle legally attached to the former owner, with the financial consequences that this entails.
