After the sale of a vehicle, the former owner remains legally responsible for any offenses committed with it until the transfer is registered in the Vehicle Registration System (SIV). Knowing whether the seller has properly declared the sale requires cross-referencing several sources of information, all digitized since the removal of the requirement to go to the prefecture. The stakes are real: radar fines, parking tickets, and even liability in the event of an accident can fall on the wrong person.
Transfer declaration deadline and status in the SIV: what each party can verify
The seller has a legal deadline of 15 days after the sale to register the transfer on the ANTS website via the online procedure “Sell or give my vehicle.” This deadline is the same for a sale between individuals and for a donation. After this period, registration is still possible, but the former owner is exposed to fines issued in the meantime.

To find out how to know if the seller has declared the sale, the buyer and the seller do not have the same tools. The table below summarizes the verification methods available to each party.
| Verification tool | Accessible to the seller | Accessible to the buyer | Information obtained |
|---|---|---|---|
| ANTS personal space | Yes | No (except for their own account) | Status of the transfer process (in progress, validated, rejected) |
| Histovec | Yes (with the registration certificate) | Yes (with the link provided by the seller) | Transfer date, change of owner, potential blocks |
| ANTS transfer code | Generated at the end of the online procedure | Received from the seller to make their registration certificate | Proof that the declaration has been initiated |

Histovec: cross-referencing the transfer date with the vehicle’s history
Histovec is the only official tool that allows the buyer to independently verify if the sale has been registered. The seller generates a report from their account and then sends a consultation link to the buyer.
This report displays the history of changes of ownership, transfer dates, and any potential administrative blocks (lien, opposition, theft). In practice, any discrepancy between the date recorded on the paper transfer certificate and the transfer date visible in Histovec indicates a registration problem.
Here are a few points to check on the Histovec report:
- The date of the last transfer matches the sale date on the Cerfa 15776*02
- No block status (lien, opposition) appears after the transfer date
- The vehicle is no longer linked to the former owner in the “owner” section
If the transfer does not appear in the days following the sale, it does not automatically mean that the seller has done nothing. ANTS processing times can vary. However, a prolonged absence of updates, beyond two to three weeks, should raise a red flag.
ANTS seller space: interpreting the statuses of the process
For the seller, verification is done through the personal space on the ANTS website. After completing the transfer online procedure, a follow-up appears with several possible statuses.
The status “validated” confirms that the transfer is registered in the SIV. A status of “under review” indicates that the file is awaiting processing. A status of “rejected” or “incomplete” means that a document is missing or an input error has been detected.
The most common reasons for rejection:
- Error in the registration number or in the identity of the buyer
- Transfer certificate (Cerfa 15776*02) incorrectly filled out or illegible
- Absence of the confidential code from the registration certificate when the process is carried out by a third party
- Technical inspection older than six months at the time of sale
A rejection is not final. The seller can correct the information and restart the process from the same space. The difficulty lies in the fact that ANTS does not always clearly notify the exact reason for the rejection, which requires checking each field of the initial form.
Fines and tickets after the sale: the concrete warning signal
Receiving a fine for an offense committed after the sale date is the most tangible sign that the transfer has not been registered. This scenario occurs more often than one might think: several insurers have reported an increase in disputes related to tickets received after a sale in recent years.
The former owner remains liable for fines until the SIV has registered the change of ownership. Contesting the fine is possible, but it requires producing the dated and signed transfer certificate, as well as proof of the online declaration.
To contest, a request for exemption must be sent to the service indicated on the fine notice, along with a copy of the Cerfa 15776*02. Without this document, the contestation is unlikely to succeed. This is why keeping a copy of the transfer certificate for several years is a basic precaution.

Cross-checking: the method to apply on the day of the sale
The most reliable verification is based on a cross-check conducted on the same day as the transaction. The seller completes the transfer online procedure on ANTS immediately after signing the Cerfa. At the end of the process, a transfer code is generated and must be transmitted to the buyer.
This code is essential for the buyer to initiate their own registration certificate request. Its existence proves that the declaration has been initiated. The buyer can then verify, via Histovec, that the transfer appears in the following days.
Waiting several weeks to verify the registration increases the risks. A check on the day of the sale, followed by a second check via Histovec within ten days, is sufficient to confirm that the entire administrative chain has functioned. The absence of a transfer code at the end of the transaction should be considered an immediate warning signal.
