Frequently Asked Questions
Where most claims come from
Claims in the sale of used cars have four main origins, and almost all of them share a common root: something that was not made clear at the time of sale.
The first is hidden defects: mechanical or structural problems that existed at the time of sale but which the buyer could not see during the inspection. Some are genuinely unforeseeable. Others are the result of not having carried out a sufficiently detailed inspection before putting the vehicle up for sale.
The second is incorrect or incomplete information: mileage that does not match the MOT history, undeclared accident history, outstanding finance or charges on the vehicle that were not verified before purchase, or equipment described inaccurately in the advertisement.
The third is warranty issues: the buyer understands that something is covered and the dealership understands that it is not. This is almost always because the contract did not clearly specify what was included in the warranty and what was excluded.
The fourth is administrative errors: vehicles that are not transferred correctly, documentation that is not handed over, notifications to the DGT (DVLA equivalent) that are not made, resulting in fines being generated in the name of the dealership weeks after the sale.
None of these four origins is inevitable. They all have a solution before they even appear.
If there are charges or outstanding finance on the vehicle that were not verified, you can consult how to remove an embargo from a car.
Before putting the car up for sale: inspection and condition documentation
The best time to avoid a claim is before the vehicle enters the stock list. A systematic inspection before publication eliminates most potential problems.
Basic mechanical check. A complete diagnostic is not needed for every car, but an inspection is required to cover the elements that most frequently generate complaints: engine condition (starting, levels, smoke), brakes and tyres, electrical system (lights, electric windows, climate control), and any visible warning lights on the dashboard. If anything is detected, there are two options: repair it before selling or document it in the contract as a known defect. What is not an option is doing nothing and hoping it won't be noticed.
Vehicle documentation verification. DGT report to confirm the absence of charges and administrative status. MOT history to verify mileage coherence over time. CARFAX report or equivalent to detect accidents registered in international databases. If there are discrepancies between the odometer and the MOT history, documenting them before selling protects the dealership from subsequent claims for incorrect mileage.
Photographs of the vehicle's condition before delivery. A photo report documenting the exterior and interior condition of the vehicle at the time of delivery has very high evidentiary value in the event of a subsequent claim. A buyer who claims that a dent in the bumper was already there before they bought it has a problem if there are signed photos from the day of delivery showing otherwise.
During the sale: what must be in writing
The purchase agreement is the document that determines the outcome of any subsequent claim. An incomplete contract is a claim waiting to happen.
Description of the vehicle's condition. The contract must include a section describing the condition of the vehicle at the time of delivery: exact mileage, known visible defects (dents, scratches, worn parts), and a statement that the buyer has had the opportunity to inspect the vehicle. A defect that is described in the contract cannot be claimed as a hidden defect.
Warranty clause with coverage and exclusions. The warranty must be precisely defined: duration (minimum of one year for used vehicles, reducible by express agreement), what it covers (types of breakdowns) and what is expressly excluded (normal wear and tear, consumables, damage from subsequent misuse). A warranty clause that only says "12-month warranty" without detailing coverage or exclusions creates expectations that may not match what the dealership intends to cover.
Buyer's declaration of conformity. A phrase in the contract indicating that the buyer has examined the vehicle, knows its condition and accepts it in the described conditions is the most direct protection against claims for defects that were observable in the pre-inspection.
To understand which clauses are legally essential and which add extra protection to the seller, you can review the guide on essential contracts in professional car sales.
The legal warranty: obligations, coverage and management
As a professional dealership, you are obliged by Royal Legislative Decree 1/2007 to offer a legal warranty to the consumer. It is not optional. However, there are aspects of its application that can be managed to reduce the risk of unjustified claims.
Duration. The legal warranty for used vehicles is two years from delivery, but it can be reduced to one year by express written agreement. If the contract does not mention duration, two years apply. If it mentions one year without explaining that it is an agreed reduction of the two legal years, the clause may be considered invalid.
Presumption of pre-existence of the defect. During the first year from delivery, defects are presumed to be pre-existing unless the dealership proves otherwise. From the second year onwards, the buyer must prove that the defect existed at the time of delivery. This difference makes the description of the vehicle's condition in the contract especially important for the first year of the warranty.
What the buyer can request. In this order: first repair or replacement (the least costly option for the dealership), then a price reduction, and only if repair is not possible or not carried out within a reasonable timeframe, termination of the contract with a refund of the price. The dealership can choose between repair and replacement if both are possible.
Warranty incident management. Every incident covered by the warranty must be documented: description of the problem, diagnosis, repair carried out and date. Such documentation serves both to prove that the warranty was met and to identify if there is a pattern of problems in similar vehicles that should be reviewed before sale.
For differences between legal and commercial warranties, see differences between legal warranty and commercial warranty in cars.
Delivery: the moment that prevents or causes the most claims
The delivery of the vehicle is the moment of greatest risk of misunderstandings and the easiest to manage with a standardised process.
Delivery note signed by both parties. The delivery note must include: exact mileage at the time of delivery, number of keys handed over, included documentation (registration certificate, technical sheet, manual, service booklet if available), fuel tank level, and any observations about the vehicle's condition that complement what has already been described in the contract.
Explanation of warranty conditions. Taking three minutes at the time of delivery to explain to the buyer what the warranty covers, what is excluded and how to manage an incident (who to call, what documentation to provide) significantly reduces claims stemming from unfulfilled expectations. A buyer who understands exactly what they have will lodge fewer and more grounded claims when they do complain.
Follow-up within 48-72 hours. A brief call or message two or three days after delivery to confirm everything is fine has three positive effects: it detects minor problems before they turn into formal claims, generates goodwill in the buyer, and is the perfect moment to ask for a Google review if all is going well.
To understand how to organise this delivery process efficiently with the digital file of each vehicle, you can consult the guide on obligatory documentation for every sales operation.
If you receive a claim: how to respond with sound judgement
A well-managed claim can be resolved in hours. A poorly managed one can lead to a consumer rights complaint or a court case.
The first step is to listen and document: ask the customer to describe the problem in detail, what symptoms the vehicle is showing, when they appeared and what documentation they can provide. Do not commit to anything during this first contact.
The second step is to review the vehicle's file: signed contract, description of the condition at the time of delivery, photographs, service history, delivery date and warranty coverage. With this information, you can evaluate if there is a legal basis for the claim.
The third step is to evaluate the claim with legal criteria: could the defect be considered hidden (not visible during ordinary inspection)? Was the problem described in the contract? Is it within the warranty period? Could the buyer's use of the vehicle have caused or worsened the problem?
The fourth step is to propose a proportional solution based on the legal standing: if there is a basis, offer repair as the first option. If there is no basis, explain why and what documentation supports this decision. Always document the response in writing, even if the claim was made verbally.
When rejecting a claim is legally correct
Not every claim has a legal basis. Rejecting it when it does not, with clear arguments and supporting documentation, is legally correct and protects the business.
You can reject a claim when the defect was described in the contract or was clearly observable in the pre-inspection and the buyer signed their agreement. When the problem is the result of using the vehicle after delivery (accident, poor maintenance, modifications). When the warranty has expired and the defect cannot be proven as pre-existing. When the buyer is a business and the agreed warranty conditions do not cover the claimed situation.
In all these cases, the rejection must be in writing, referencing the contract and the clause or circumstance that justifies the decision. A verbal rejection without supporting documentation is harder to defend if the claim escalates.
To understand what rights the buyer has in each situation and the timeframes that apply, you can consult the article on what to do if the customer wants to return the car.
Errors that turn an avoidable claim into a real problem
Not taking photographs of the vehicle's condition before delivery. Without dated photos, the dealership cannot prove that a damage the buyer claims existed before purchase did not exist at the time of delivery. Photos take five minutes and save months of conflict.
Not describing known defects in the contract. A defect that is not in the contract cannot be defended as "known by the buyer". Describing defects is not a deterrent to the sale: it is the only real protection against a subsequent claim for that defect.
Offering a verbal warranty without reflecting it in the contract. What the seller promises verbally at the time of sale can be claimed as a verbal agreement, even if it is not in the contract. If the verbal promise goes beyond what the contract contains, the dealership may find itself held to that promise.
Not notifying the DGT of the sale before the buyer registers the change of ownership. If the buyer gets a fine or has an accident before transferring the vehicle and the dealership has not notified the DGT of the sale, liability may fall on the registered owner. This situation generates claims against the dealership that have nothing to do with the car's condition.
Responding to claims without reviewing the file. Committing to a repair or a refund before reviewing the contract and the vehicle's documentation can mean taking on commitments that are not legally enforceable. The file is the first thing that must be checked before any response.

Frequently Asked Questions
How long does the buyer have to make a claim for a hidden defect?
The timeframe to claim for lack of conformity is two years from the vehicle's delivery (or one year if expressly agreed). During the first year, defects are presumed to be pre-existing. From the second year onwards, the buyer must prove that the defect existed at the time of delivery.
Can I demand that the buyer bring the car to my workshop for a warranty check?
Yes. The dealership can specify in the contract that repairs covered by the warranty must be carried out at the designated workshop or one of its network. If the buyer takes the car to another workshop without prior authorisation, the dealership may not be obliged to cover that repair.
What happens if the buyer goes to consumer protection before contacting the dealership?
The consumer protection body will normally try mediation before starting any procedure. If the dealership has its documentation in order (detailed contract, condition description, photos, clear warranty coverage), its position in that mediation is much stronger. Without documentation, mediation tends to favour the consumer.
Can I include a clause in the contract that says "vehicle sold in sold-as-seen condition, without warranty"?
Not completely. The legal warranty cannot be eliminated by a contractual clause when the buyer is a consumer. A clause of this type is null and void. What can be done is reduce the duration of the warranty to one year by express agreement, and exclude known and described defects from the contract.
