Used Car Legal Warranty in Belgium: 2 Years or 1 Year

From a professional seller, the legal warranty on a used car lasts two years in Belgium. The seller can cut it to one year, not below, provided it is written clearly at the time of sale. Between private individuals it does not exist: the hidden-defect remedy remains.

The legal warranty is the seller's obligation to deliver a conforming item and to repair, replace or refund any defect that already existed at delivery and appears within the covered period.

Which warranty applies depending on the seller?

It all depends on who signs the invoice. The seller's status decides the duration, not the brand or the price of the car.

The warranty falls under federal consumer law. It is therefore identical in Wallonia, Brussels and Flanders. Only the competent court changes with where you live.

Is a three-month in-house warranty valid?

No, not as a substitute. This is the most common trap in showrooms.

A seller advertises "3-month warranty" or "6-month warranty, parts and labour". It sounds like protection and is often a disguised reduction. Test-Achats is clear: the period can be shortened, but never below one year, and only if it was clearly stated at purchase. A two-month warranty is not valid, and the two years automatically return.

A commercial warranty can be added to the law. It cannot trim it.

What does the warranty cover, and what does it leave out?

The warranty targets a defect present at delivery but unknown to the buyer. During the covered period, the defect is presumed to have existed from the start unless the seller proves otherwise, which spares the buyer from proving the origin of the breakdown.

Checkpoints before signing:

• defects written on the order form or contract can no longer be invoked;
• normal wear (tyres, brake pads, battery, exhaust) is excluded;
• a repair done by a third party without the seller's agreement complicates what follows;
• mileage and history must match the Car-Pass handed over at sale;
• a defect known at purchase, even verbally, will be turned against you if the seller can prove it.

What should you do when the car breaks down?

Seven steps, in this order. Total time before any court action: a few days to a few weeks.

1. Stop driving if the defect is a serious mechanical one, and photograph the dashboard, the error message and the odometer. Time: 10 minutes. Cost: 0 euros.
2. Find the paperwork: order form, invoice, Car-Pass, any warranty certificate. Check whether a reduction to one year is written down. Time: 15 minutes.
3. Notify the seller in writing within two months of discovering the defect. Registered letter and email, with a description of the problem. Registered post costs a few euros.
4. Ask for free repair or replacement. This is the first right provided by law, before any price reduction.
5. Allow a reasonable delay. If the repair takes too long or fails, you can claim a price reduction or, if the defect is serious enough, cancel the sale against a refund.
6. Have an independent expert report if the garage disputes it. Usual cost: 300 to 600 euros, according to Justifit.
7. Go to the Point de contact or mediation after a written amicable letter, then to court as a last resort.

What if you buy from a private seller?

There is no legal warranty, but hidden defects remain, a heavier remedy. You must prove that the defect existed before the sale, that it was invisible, and that it prevents normal use of the car. The procedure goes through a registered letter, an expert report, then possibly the judge.

Clauses such as "sold as is" or "without warranty" are not always an obstacle, because protection against hidden defects is not mandatory between individuals: they can be valid, and a good-faith seller often relies on them. Justifit gives the benchmark of an action brought promptly, with two years and six months after the expert report as limits. That is a secondary source: a lawyer should confirm this deadline before you act.

For an imported car, the logic is the same as for a Belgian used car, with a higher risk of odometer fraud: our guide to importing from Germany covers that case.

How much does it cost to defend your rights?

The break-even point is easy to work out. An expert costs 300 to 600 euros. Court proceedings are estimated at 3,000 to 5,000 euros in costs advanced by the buyer, refunded by the other party if the buyer wins (Justifit, page reviewed in October 2025).

Thresholds proposed by the editors from Justifit's ranges: they are not a legal rule.

Legal-protection car insurance may cover the expert. Check your contract before paying out of your own pocket.
