Damage to a borrowed car: who pays, and what do you write in the damage report?

Lending the car to a friend, neighbor, or family member is common – until something happens. Then the classic questions arise: Who pays? What insurance applies? And not least: What should we write in the damage report for the process to go smoothly? Here is a practical review (we are in 2026), based on normal practices in Norwegian car insurance – but remember that terms may vary between insurance companies.

Who pays when a borrowed car is damaged?

In Norway, it is basically the car's insurance that applies, because the insurance follows the vehicle – not the person driving. This means:

• Injuries to others (liability): The traffic insurance covers personal injury and damage to other people's property when the car is in use, regardless of who is driving legally (as long as the driver is not a case of theft).
• Damage to the car itself: This depends on whether the car has partial coverage/comprehensive coverage and what the damage is (collision, off-road driving, parking dent, theft, etc.).

But even if the insurance "pays," the cost may practically fall on the car owner and/or borrower through a deductible, bonus loss, and price increase upon renewal. Many resolve this privately by having the borrower cover the deductible or the entire amount if the damage is not reported.

Typical scenarios

• You crash alone (own accident): Comprehensive insurance may cover repairs, but the car owner often has to pay the deductible and may incur a bonus loss.
• You damage another car and are at fault: The liability part covers the other party; your own car requires comprehensive coverage for repairs.
• Parking damage without known perpetrator: Comprehensive insurance can cover (terms vary), but documentation is important.

What you must do immediately after the accident

Regardless of whether the car is yours or borrowed: secure the scene, assist the injured, and get an overview. In the event of a traffic accident, you also have obligations under road traffic legislation, and the police describe what you should do and when you must notify. See Police: traffic accident.

• Stop and secure: Turn on hazard lights, use a reflective vest and warning triangle.
• Exchange info: Name, phone number, registration number, insurance company, and driver's birth date (if possible).
• Document: Take photos of damages, the vehicles in position, road markings, signs, and an overview image.
• Witnesses: Note names and numbers.

What do you write in the damage report when the car is borrowed?

The most common mistake is being vague, or writing "car owner" where it was actually the borrower who was driving. The insurance company needs a clear factual basis. The Norwegian Public Roads Administration has a useful overview of damage reports and what should be included: Norwegian Public Roads Administration: damage report.

1) Provide the correct driver and owner

The damage report should state:

• Who owns the car (policyholder/car owner).
• Who actually drove (borrower) – with contact info and driver's license details where the form requests it.

This is especially important if the car owner was not present. Do not "simplify" by listing the owner as the driver.

2) Describe the incident briefly, concretely, and without interpretation

Write what happened in chronological order:

• Where (road, intersection, direction, time, and weather/road condition).
• What you did (e.g., "backed out of the parking space").
• What the other party did (if relevant), without attributing motivation ("did not see me").
• Where on the car the damage is (e.g., "right rear fender, paint damage and dent").

Avoid blame-words such as "I was stupid" or "it was entirely my fault." You can be honest, but stick to observable facts; the distribution of responsibility is handled by insurance companies.

3) Draw the sketch – and take a picture of it

The sketch is often the most important in case of doubt. Mark roads, arrows, right of way, parking, and vehicle positions. If you fill it out digitally, ensure that the sketch is clear.

4) Check off for cause of damage and attach documentation

Select the correct type of incident (collision, reversing, off-road driving, glass, theft, etc.). Attach:

• Photos (preferably 8–15 in different angles)
• Witness info
• Possibly police number/case number

Deductible, bonus loss, and "who should pay" privately

Even if the damage is reported to the car's insurance, it is common for the borrower and car owner to agree privately on how the deductible/bonus loss is handled. Some guidelines:

• If the borrower is responsible for the damage: the borrower often pays the deductible (and sometimes an amount equivalent to the expected bonus loss).
• If the other party is responsible: the other party's insurance usually covers it, and the car owner should not normally be charged a deductible for the liability damage (but practice may vary in process and recourse).
• If the perpetrator is unknown (e.g., parking dent): comprehensive coverage may provide a deductible and possible bonus effect – check the terms.

The bonus system, deductibles, and small differences in terms mean that you should always check the car's insurance agreement before you decide to "take it privately." Sometimes it is cheaper to report, other times it is not.

This is how Skademeldinger.no makes the process easier

When the car is borrowed, one of the challenges is that the car owner and driver often do not occupy the same space. With Skademeldinger.no, you can fill out the damage report together (also when you are on different phones), ensure that you end up with one shared version, and sign digitally. Then it can be shared/downloaded and sent on – ready for the insurance company. This reduces misunderstandings that can otherwise cost time.

Frequently asked questions

Can the insurance deny because the car was borrowed?

As a general rule no, as long as the driver was allowed to use the car and otherwise met the terms (valid driver's license, not under the influence, etc.). However, some agreements may have restrictions related to age/experience or who is listed as the primary driver – therefore: check the terms in the car's insurance.

Do we always have to involve the police?

Not for minor material damages, but in case of personal injury, disagreement, suspicion of intoxication, or if someone leaves the scene, it may be necessary. See Police: traffic accident for guidance.

What if the borrower does not want to report the damage?

If the car owner wants repairs through insurance, the damage normally has to be reported to the insurance company. A tidy damage report with good documentation makes it easier to clarify responsibility and move forward quickly.

Checklist before you submit

• Correct driver provided (borrower) and correct owner (policyholder)
• Clear incident description without speculation
• Sketch and photos are attached
• Counterparty's info is complete, and you agree on the facts
• Digital signature or clear confirmation from both parties

Summary: In the event of damage to a borrowed car, it is usually the car's insurance that handles the damage, but deductibles and bonus loss can become a topic between you. Fill out the damage report accurately (especially who was driving), document thoroughly – and feel free to use Skademeldinger.no to get a shared, signed damage report that can be sent directly to the insurance company.
