Car sale contract: template for a private sale

Every year, hundreds of thousands of used cars change hands in Denmark, most of them through private sales. A private car sale is often the cheapest way to buy or sell a car, but it is also the type of sale that most often ends in conflict. The reason is almost always the same: there is no written agreement.

A car sale contract, also called a bill of sale or purchase contract, is the document that protects both parties. It sets out precisely what has been agreed, in what condition the car is sold, and who is liable for what. Without it, you are either a buyer or a seller with a promise you cannot prove.

This guide reviews what a car sale contract should contain, which rules apply to private car sales in Denmark, and what you should be aware of to avoid the classic pitfalls.

Why do you need a sale contract when selling a car?

An oral agreement is legally binding in Denmark. But it is extremely hard to prove if there is disagreement about what was actually said and agreed.

A written car sale contract:

• Documents the condition: what was the car's condition at the time of the sale, and what were both parties aware of?
• Sets out the price and payment terms: when is payment made, and how?
• Protects the seller from future complaints: if the car is sold in the condition it appears, and this is agreed in writing, the seller's liability is limited
• Protects the buyer: among other things against cars with a charge, undisclosed accident history or manipulated odometer readings

For many, buying a car is the largest single expense after their home. A sale contract template costs nothing to use, but lacking one can cost many thousands of kroner.

What should a car sale contract contain?

A useful car sale contract should as a minimum contain the following elements:

1. Identification of the parties

State the seller's and buyer's full name, address and civil registration number (or CVR number if the seller is a business). This is necessary for the contract to be used as evidence and for the change of ownership at the Danish Motor Agency to be completed correctly.

2. Identification of the car

This is the technical backbone of the contract:

• Chassis number (VIN): the vehicle's unique identification number, typically 17 characters
• Registration number: the car's number plates
• Make, model and year
• Colour
• Odometer reading at the time of the sale

The chassis number is especially important. It is the safest evidence that the contract concerns exactly the car you traded.

3. Price and payment terms

State the agreed price clearly, and specify:

• The total price in DKK
• The method of payment (bank transfer, cash, MobilePay)
• The time of payment: at handover of the keys, before handover or after inspection?
• Whether the price includes or excludes number plates and duties

Tip: Use a bank transfer and keep the receipt. Note that the cash ban in the Anti-Money Laundering Act (section 5) prohibits traders from receiving cash payments of DKK 20,000 or more. In a private sale, the ban does not apply directly, but a documented bank transfer is still far preferable for evidence.

4. The car's condition and known faults

This point is decisive for the seller's legal position. Describe:

• The car's general condition (good, normal, cosmetic wear, mechanical faults etc.)
• Known faults and defects, specifically stated (for example "scratch in the windscreen", "ABS light on", "air conditioning without gas")
• Whether the car has been involved in accidents or has bodywork repairs
• Inspection report: the date of the latest inspection and any registered remarks

Never write "no known faults" in the contract if you are unsure. If hidden faults appear later, it is a potential point of liability.

5. Debt and encumbrances

The seller should confirm in writing that the car:

• Is free of a registered charge (check the Car Register via tinglysning.dk)
• Is not registered as stolen
• Is not subject to attachment or seizure

The buyer should always check the car's debt status before signing, for example in the Car Register or via a vehicle history report.

6. Date of transfer and handover of keys

State the date the car is physically handed over, and when the keys, service book and any spare keys are delivered. This also matters for delimiting insurance liability.

7. Both parties' signatures

The contract has limited value without a signature from both the seller and the buyer. Always date the signature, and make two copies, one for each party.

Step by step: how to make a car sale contract

1. Fill in the parties' details. Enter the full name, address and civil registration or CVR number for both seller and buyer. Check that the details match the ID and driving licence.
2. Identify the car precisely. Note the chassis number, registration number, make, model, year, colour and odometer reading.
3. Agree and specify the price. State the full price, the method of payment and the time of payment. "Paid at handover of keys via MobilePay" is better than "paid on sale".
4. Describe the car's condition honestly. Note all known faults, defects and damage. Do not write "no known faults" unless you are completely sure. Attach the latest inspection report if possible.
5. Confirm that the car is debt-free. The seller declares that the car is free of a charge. The buyer should double-check in the Car Register or via a vehicle history report before signing.
6. Sign and date. Both parties sign, and two copies are made. A digital signature provides automatic documentation.
7. Re-register the car. Report the change of ownership in the Motor Register (DMR) via skat.dk. Make sure the buyer takes out insurance before driving home.

The buyer's and seller's liability in a private car sale

The seller's liability

In a private sale, the Sale of Goods Act applies, but it is decisive whether the seller is a consumer or a business.

Private seller (consumer to consumer): The seller is liable for defects that existed at the time of the sale and that the buyer should not have discovered, unless they are stated in the contract. A precise description of the condition in the contract protects the seller: if it states that "the car is sold as it is and shown, with the faults and defects disclosed", and these are specified, it significantly limits the liability. The seller cannot, however, disclaim liability for faults that are deliberately concealed or withheld.

The buyer's rights

In a consumer-to-consumer sale, the special consumer-protective rules of the Sale of Goods Act do not apply. The buyer therefore does not have the same strong protection as when buying from a dealer.

This means:

• There is no presumption rule (reversed burden of proof) in a private sale. If the buyer wants to assert a defect, it is as a rule the buyer who must prove that the defect already existed at handover
• Ordinary wear and tear is not a defect. Cars are typically sold with a degree of reservation
• The seller can validly make reservations and disclaim liability for disclosed faults

Never buy a used car from a private seller without inspecting it thoroughly, and for larger deals consider an independent mechanic's assessment.

Typical pitfalls in a private car sale

A charge on the car

It is fully lawful to sell a car that is charged for a car loan, but it can incur liability not to tell the buyer about it. In the worst case, the buyer risks losing the car if the seller does not repay the debt after the sale.

Solution: The buyer should always check the car in the Car Register (tinglysning.dk) before the sale. The seller should declare in writing in the contract that the car is debt-free, or state the debt expressly and agree that it is redeemed on the sale.

False or manipulated odometer readings

Odometer fraud unfortunately still occurs. It is a criminal offence, but hard to prove afterwards without documentation.

Solution: Obtain a vehicle history report. It shows historical inspections and registered odometer readings over time.

A missing or expired inspection

A car without a valid inspection cannot lawfully be used on public roads where inspection is required. The seller can sell a car with an expired inspection but should disclose it.

Solution: Always note in the contract whether the inspection is valid and when it expires.

Hidden damage and undisclosed repairs

Cars with major bodywork or mechanical damage that is hidden by paint, upholstery or other cosmetic repair are a classic pitfall.

Solution: Inspect the car thoroughly, possibly on a lift at a mechanic's. Ask directly about any accidents and bodywork repairs. A vehicle history report can show insurance damage from major accidents.

Number plates

The seller normally keeps the number plates on a sale. The new owner must either register new plates or use trade plates for the drive home.

What does the law say about a private car sale?

The Sale of Goods Act

A private car sale in Denmark is governed by the Sale of Goods Act, which governs agreements on the sale of movables, including cars. In a private sale (consumer to consumer):

• The seller is liable for defects that existed at the passing of risk (typically at handover) and that are not disclosed
• There is no presumption rule: the buyer as a rule bears the burden of proving that a defect existed at handover
• The seller can make reservations and disclaim liability for disclosed faults

Consumer purchase vs. private sale

It makes a decisive difference whether you buy from a dealer (business) or from a private seller. When buying from a business, the consumer-protective rules of the Sale of Goods Act apply with a 2-year right to complain, and a presumption rule (reversed burden of proof) applies for the first year after the purchase, during which the seller must prove that a defect did not exist at delivery. In a private sale, you as the buyer are significantly weaker positioned.

The Anti-Money Laundering Act

The cash ban in the Anti-Money Laundering Act (section 5) prohibits traders from receiving cash payments of DKK 20,000 or more. Whether you trade privately or commercially, you should document the payment electronically, for example via a bank transfer.

Re-registration and insurance of the car

The change of ownership is not complete on signature and payment. You must also:

Report the change of ownership to DMR

The change of ownership must be reported to the Motor Register (DMR) via skat.dk, at the latest when the buyer takes over the car. The seller bears the registration-related responsibility until the change of ownership is registered, and thereby also for any traffic fines, duties and insurance matters.

Both parties can report the change of ownership digitally via skat.dk with MitID. It is quick and free.

Take out insurance before driving

The buyer must take out insurance on the car before the first drive after taking over. Driving without the mandatory third-party insurance is illegal and can lead to a fine and liability for damages in an accident.

Number plates

The seller normally keeps the number plates. The buyer can apply for new plates via DMR or use trade plates for the drive home (available for a fee from inspection companies and number-plate operators).

Frequently asked questions about the car sale contract

What is the difference between a sale contract and a bill of sale for a car?

A bill of sale and a sale contract are in practice the same document, namely a written agreement on the purchase and sale of a used car. "Bill of sale" is the more traditional term, "sale contract" the more formal one. Both cover the same need: written documentation of the terms of the deal.

Is a sale contract mandatory when selling a car?

No, there is no legal requirement for a written sale contract in a private car sale in Denmark. But it is strongly recommended, because without a written agreement it is very hard to prove what was agreed if a disagreement arises.

What happens if the car has a charge that the seller has not disclosed?

If the car is charged and the seller does not disclose it, it can, depending on the circumstances, be criminal as fraud. The buyer can as a rule cancel the deal and possibly claim damages. Always check the car's debt status in the Car Register before the deal.

Can I withdraw from a private car purchase?

In a private sale (consumer to consumer) there is no statutory right of withdrawal. The right of withdrawal in the Consumer Contracts Act applies only to certain agreements made with a business, typically distance sales and agreements made away from the business's premises, not to private car sales. Therefore inspect the car thoroughly before signing.

What is a chassis number, and where do I find it?

The chassis number (VIN) is a unique identification number of typically 17 characters. It can typically be seen at the bottom of the windscreen from the outside, under the bonnet, on the registration certificate and in the service book. The chassis number is decisive for identifying the car unambiguously in the contract.

Who reports the change of ownership to DMR, the seller or the buyer?

Both parties can report the change of ownership via skat.dk. In practice, it is recommended that both report, so no delays arise. The seller bears the responsibility until the change of ownership is registered.

Can the seller disclaim all liability for defects?

The seller can make reservations and disclaim liability for known and specified defects by stating them in the contract. The seller cannot, however, disclaim liability for defects that are deliberately concealed or withheld. A general reservation like "sold as seen" gives some protection, but not an absolute release from liability.

Can I use a digital car sale contract?

Yes. A digitally signed sale contract is legally equal to a physical signature under Danish law and the eIDAS Regulation.

Conclusion

A car sale contract is not bureaucracy but the shortest route to a deal that does not end in conflict. Whether you are selling your old family car or buying a used commuter car, the written agreement is your most important tool. Use a template that covers all the points: the parties, the chassis number, the price, the condition, the debt and the date of transfer. Always check the car's debt status in the Car Register before signing, and re-register the car immediately via DMR.
