After the sale of a vehicle between private individuals, the seller loses all access to the registration file recorded in the Vehicle Registration System (SIV). The transfer declaration has been made, the transfer code sent to the buyer, and the registration certificate crossed out and handed over.
One concrete question remains: has the new owner actually completed the change of registration certificate to their name? No public online service currently allows the seller to verify this directly.

Access to the SIV after the transfer: what the seller can and cannot consult
The SIV centralizes all vehicle registration data in France. Once the transfer declaration is recorded via the ANTS, the seller no longer has access to the registration file of the transferred vehicle. This point is confirmed by the ANTS in its notices on access rights to SIV data.
Only law enforcement and certain authorized professionals can consult the current holder of a registration certificate in real-time. To find out how to know if the buyer has changed the registration certificate, one must rely on indirect clues or specific administrative procedures, as no online verification is accessible to private sellers.

The often-cited HistoVec website allows for generating a report on a vehicle’s history, but it is designed for the current owner or potential buyer. A former owner attempting to access it with their old credentials encounters a block once the transfer is declared.

Fines and infractions received after the sale: the concrete warning signal
The first clue that a buyer has not changed the registration certificate often comes by mail. Fines for parking, speeding, or unpaid tolls continue to arrive in the name of the former owner because the vehicle is still registered in their name in the SIV.
This situation is not uncommon. Several prefectures and police services direct sellers facing this issue towards a contestation procedure. The process relies on a central document: the transfer declaration receipt (cerfa 15776*02) generated by the ANTS during the online procedure “Sell or give my vehicle”.
Contesting a fine received after the transfer
To free themselves from any responsibility, the seller must send a request for exemption to the competent Public Prosecutor’s Officer. The required documents are specific:
- The transfer declaration receipt bearing the date and time of the sale, which proves that the infraction occurred after the transfer
- A copy of the crossed-out registration certificate with the mention “Sold on” or “Transferred on,” the date, time, and signature of the seller
- The original notice of contravention received, accompanied by the pre-filled exemption request form
This contestation works, but it requires the seller to carefully keep all transfer documents. Without the ANTS receipt, proving the transfer becomes difficult.
Transfer declaration on the ANTS: the seller’s only real lever
The online transfer declaration via the ANTS is the seller’s only preventive action. It creates a time-stamped record in the SIV that legally protects the former owner, even if the buyer delays in making their own change of holder procedure.
The buyer has one month to complete the change of registration certificate after the sale. After this period, they are in violation. However, the seller receives no notification confirming that the transfer has been finalized on the buyer’s side.
The transfer code, a often overlooked document
At the end of the online transfer procedure, the ANTS generates a transfer code that the seller must pass on to the buyer. This code is essential for the new owner to initiate their online registration certificate request. If the seller does not communicate it, or if the buyer loses it, the procedure gets blocked.
Several field reports show that buyers delay changing the registration certificate precisely because they have not received or have misplaced this code. Checking before parting ways that the buyer has noted it down remains the most effective precaution.

Recourse by law enforcement: a possible but not guaranteed consultation
Gendarmes or police officers can consult the SIV and confirm to the seller whether the vehicle is still registered in their name. Several feedbacks from road law attorneys, between 2023 and 2024, indicate that this verification occurs occasionally, particularly during a complaint filing or a report related to wrongly received infractions.
This consultation is not an officially offered service to the public. A seller cannot simply show up at the gendarmerie to check the registration status of a transferred vehicle. The process rather occurs within the context of a documented dispute, with supporting contraventions.
When to consider a formal report
If several months after the sale, fines continue to arrive and the buyer no longer responds, some prefectures recommend what the administration calls a “withdrawal of transfer.” This procedure allows the seller to report that the buyer has not completed the necessary steps and to protect themselves against future fines.
The documents required for this procedure largely overlap with those for contesting a fine:
- The ANTS transfer declaration receipt with the registration number
- A copy of the cerfa 15776*02 transfer certificate signed by both parties
- Proof of attempts to contact the buyer (letters, messages)
- The administrative situation certificate (formerly non-gage certificate) obtained via HistoVec before the sale
Careful preservation of the sale file remains the best protection for the seller. Without the transfer declaration receipt, proving the transfer of ownership becomes a long and uncertain process. The current system does not provide any automatic notification to the seller once the registration certificate change has been made by the buyer, leaving an administrative blind spot that only documentary vigilance can fill.
