When a vehicle is sold between private individuals, the seller remains legally linked to the registration certificate until the buyer has made the change of ownership. Fines, illegal parking, infractions caught by radar: everything continues to happen in the name of the previous owner. Knowing whether the buyer has actually taken the step to update the registration certificate allows for quick action in case of problems.
Transfer declaration on France Titres: the seller’s administrative record
Before even wondering if the buyer has changed the registration certificate, the seller must have fulfilled their own obligation. The transfer declaration (Cerfa form 15776) registered online on the France Titres website (formerly ANTS) generates a registration acknowledgment and a transfer code.

This transfer code constitutes the first tangible proof that the sale has been declared on the seller’s side. It is passed on to the buyer so they can finalize the change of ownership. Without this prior declaration, the administration has no record of the transaction, and the seller has no leverage to free themselves from responsibility.
A often overlooked point: the transfer declaration must be made within a strict timeframe after the sale. Once registered, it creates a chain of evidence accessible by the administration, which facilitates any subsequent disputes if infractions occur in the seller’s name. To find out how to check if the buyer has changed the registration certificate, this preliminary step is essential.

Check the change of registration certificate: concrete methods
Once the transfer declaration is registered, the seller has several means to know if the buyer has indeed put the vehicle in their name.
Consult their France Titres space
The personal space on France Titres retains the history of actions related to the vehicle. If the change of ownership has been carried out by the buyer, the status of the transfer evolves in the case tracking. The vehicle gradually disappears from the elements associated with the seller’s account.
Monitor administrative mail
Are fines or parking notices still arriving in your name several weeks after the sale? This is the most concrete sign that the buyer has not made the change of ownership. Normally, once the registration certificate is updated, the infractions automatically transfer to the new owner.
Contact the prefecture or France Titres
In case of persistent doubt, it is possible to directly inquire with the competent service. With the registration number and the transfer acknowledgment, the administration can confirm if a change of ownership has been recorded. The response does not provide the identity of the new owner (protected personal data), but confirms or denies the transfer.
Digital registration certificate via France Identité: a new control tool
The France Identité application now allows users to import their registration certificate in digital form. This development changes the game for verifications. Once the vehicle is registered in the application by the new owner, law enforcement can check the consistency between the declared owner and the user of the vehicle.
For the seller, this digitization has an indirect consequence: a vehicle still circulating under the old owner despite a declared sale will be spotted more easily during road checks. This increases pressure on the buyer who delays regularizing their situation.
Car insurance and non-transferred registration certificate: the unknown lever
Insurers systematically require an updated copy of the registration certificate to establish or modify a car insurance contract. A buyer who has not put the registration certificate in their name finds themselves in a precarious insurance situation:
- The contract may remain in the name of the previous owner, which poses a problem in case of a claim
- The insurer may refuse coverage if the holder of the registration certificate does not match the policyholder
- In case of an accident, the insurance company may invoke a false declaration to free itself from its obligations
This mechanism offers an additional lever to the seller. If the buyer has taken out insurance, they must have provided a registration certificate, which implies they have initiated the change of ownership process. Conversely, the absence of a registration certificate transfer weakens the buyer’s insurance coverage, which should motivate them to regularize quickly.

What to do if the buyer does not change the registration certificate after the sale
Despite reminders, some buyers do not proceed with the change of ownership. The seller is not powerless, provided they have registered their transfer declaration.
- Contest each fine received by producing the acknowledgment of the transfer registration and the transfer certificate signed by both parties
- Report the situation on France Titres using the reporting function for a change in the vehicle’s status
- Send a formal notice in writing to the buyer (registered letter with acknowledgment of receipt) to remind them of their legal obligation
- As a last resort, take the matter to the local court if fines accumulate and the buyer remains unreachable
The transfer certificate signed by both parties remains the key document for any dispute. Without this document, proving that a sale took place becomes significantly more complicated.
The registered transfer declaration, the retained acknowledgment of receipt, and regular monitoring on France Titres: these three elements form the foundation of protection for the seller. A buyer who delays putting the registration certificate in their name exposes themselves to insurance difficulties and penalties, which generally ends up accelerating the regularization process.
