In France, the insurance code requires that all motorized land vehicles be covered by liability insurance. This obligation pertains to the vehicle itself, not to the person listed on the registration document. A regular driver, a family member, or a close friend can therefore take out a car insurance policy for a vehicle they do not own, provided they adhere to specific guidelines.
File of Insured Vehicles: What Has Changed for Car Contracts
Since April 1, 2024, the paper green card and the windshield sticker have been abolished. Insurance verification is now conducted exclusively through the File of Insured Vehicles (FVA), accessed in real-time by law enforcement based on the license plate.
This shift has a direct consequence when the policyholder is not the holder of the registration document. The FVA records the registration and contract number, regardless of the owner’s name. Insurers have therefore become more vigilant about the consistency between three elements: the declared main driver, the owner listed on the registration document, and the actual use of the vehicle.
A discrepancy detected during a claim can lead to reclassification as a false declaration. The penalty ranges from reduced compensation to outright nullification of the contract. This risk existed before 2024, but the automated consultation of the FVA makes cross-checking much more systematic.

Car Insurance and Registration Document: Documents Required for Non-Owner Policyholder
When the policyholder differs from the owner, the insurer systematically requests additional documentation. The standard file includes several documents.
- A copy of the vehicle’s registration document, in the name of the owner, to verify the registration and technical characteristics
- A written authorization from the owner confirming that the policyholder is allowed to use and insure the vehicle
- The driver’s license of the declared main driver, as well as a statement of information attesting to their insurance history
- Proof of the relationship between the policyholder and the owner (family relationship, loan agreement, provision agreement)
Some insurers refuse files where no clear link justifies the use of the vehicle by a third party. However, situations of family lending (parent-child, unmarried couple) or regulated professional use are more easily accepted.
Main Driver or Secondary Driver: Two Statuses, Two Levels of Risk
The choice of status declared in the contract determines the level of coverage and the cost of the premium. The main driver is the one who uses the vehicle most often. The insurer calculates the premium based on their risk profile: age, length of license, no-claims bonus, history.
Declaring as the main driver a person who only occasionally drives the vehicle, solely to benefit from their no-claims bonus, constitutes a false declaration. This arrangement, sometimes referred to as “insurance name lending,” is one of the most common reasons for denial of compensation in the event of an accident.
The secondary driver, on the other hand, benefits from the coverage of the contract without their own bonus being directly affected. This status is suitable when the use remains occasional. Any change in the frequency of use must be reported to the insurer, otherwise the coverage may be contested in the event of a claim.
Case of a Vehicle Lent to a Young Driver
Adding a young driver as a secondary driver on the contract of a family vehicle is a common practice. The insurer then applies a surcharge, but the young driver begins to accumulate insurable experience. This arrangement works as long as the declared main driver is indeed the one who drives the vehicle the most.

Automated Control and Non-Insurance: Increased Risk for Vehicles Used by a Third Party
The strengthening of automated controls through radars capable of detecting uninsured vehicles also targets situations where a vehicle is operated under a poorly declared contract. A vehicle may appear insured in the FVA while being inadequately covered if the usual driver is not the one declared in the contract.
In the event of an accident, the insurer conducts its own investigation. If the driver at the wheel at the time of the incident does not match the declared profile, the company may invoke the nullification of the contract for intentional false declaration. The driver then finds themselves personally liable for damages, without coverage.
The Guarantee Fund for Mandatory Insurance (FGAO) compensates victims in these cases but then seeks to recover the amounts paid from the responsible driver. The financial consequences of a failure to declare far exceed the cost of a properly calculated premium.
What Car Insurance Policy to Choose for a Vehicle That Does Not Belong to You
The choice between third-party insurance and a comprehensive policy depends less on the status of the policyholder than on the value of the vehicle and its use. For an old vehicle with a low replacement value, third-party insurance (liability) is sufficient in most cases.
For a recent vehicle lent by a relative, an intermediate policy including theft and fire better protects the owner’s interests. A comprehensive policy is justified when the vehicle’s value remains high and the use is daily.
One often overlooked point: the deductible remains the responsibility of the policyholder, not the owner, unless there is a written agreement to the contrary between the two parties. Clarifying this point before subscribing avoids disputes in the event of a claim.
Insuring a vehicle that one does not own remains a legal and regulated process. The abolition of the green card in favor of the FVA and the strengthening of automated controls make transparency with the insurer more necessary than ever. Correctly declaring the main driver, providing the requested documentation, and adapting the policy to the actual use of the vehicle are the three points on which the solidity of the contract rests.
