Warranty against hidden defects: conditions, remedies and time limits for taking action

​

A major defect appears after the purchase of an item: can the buyer obtain cancellation of the sale, a price reduction or compensation?

The legal guarantee against hidden defects protects the buyer when a flaw, not apparent at the time of sale, renders the property unfit for its intended use or significantly diminishes its usefulness. It applies to both sales between private individuals and sales involving a professional, and can be applied to both movable and immovable property.

However, its implementation requires compliance with several conditions and, above all, action within the prescribed time limits. Since the rulings issued by the combined chambers of the Court of Cassation on July 21, 2023, the statute of limitations for this action is now more clearly defined.

What is a hidden defect?

Article 1641 of the Civil Code requires the seller to guarantee against hidden defects in the goods sold when they render them unfit for the use for which they are intended or when they diminish this use to such an extent that the buyer would not have acquired it, or would have offered only a lower price, if he had known of them.

To be covered by the legal guarantee, the defect must meet several conditions.

A sufficiently serious defect

A simple imperfection, normal wear and tear, or a minor defect is not sufficient. The defect must compromise the normal use of the item or significantly reduce its value.

Depending on the circumstances, the following may constitute hidden defects:

• a major mechanical failure affecting a vehicle;
• a manufacturing defect that compromises the operation of a machine;
• an infiltration or structural weakness affecting a building;
• contamination, a defect or a technical non-conformity rendering a product unusable;
• a defect that permanently affects the performance of professional equipment.

The assessment always depends on the contractually intended purpose of the property, its characteristics, its age, and the information provided during the sale.

A defect not apparent at the time of purchase

The defect must have been hidden at the time of sale. The buyer cannot, in principle, claim a defect that they knew about or that a reasonably careful examination should have allowed them to discover.

This assessment varies depending on the buyer's qualifications. The technical skills expected of a professional buyer are not necessarily those of a consumer or a private individual.

A visible defect is therefore generally not covered by the warranty against hidden defects. On the other hand, a defect of which only superficial manifestations were perceptible may remain hidden if its origin, severity, or consequences could not be identified at the time of sale.

A defect that existed prior to the sale

The defect, or at least its cause, must have existed at the time of the transfer of ownership.

It is not essential that the fault or damage have already manifested themselves at that date. However, the buyer must demonstrate that the malfunction originated from a pre-existing defect and not from misuse, lack of maintenance, or a subsequent event.

This question frequently constitutes the main issue in the dispute.

Who has to prove the existence of the hidden defect?

In principle, it is up to the buyer to prove:

• the existence of the defect;
• its seriousness;
• its hidden nature;
• its prior existence before the sale;
• as well as the date on which he became aware of it.

A simple statement or the production of a repair invoice is not always sufficient. As soon as the problem appears, it is recommended to keep the item as is and gather all relevant documents: contract, order form, invoice, advertisement, photographs, correspondence with the seller, technical reports, maintenance invoices and proof of expenses incurred.

An amicable, adversarial expert assessment can help identify the source of the defect and seek a negotiated solution. In case of dispute, a court-ordered expert assessment can be requested before any substantive legal proceedings.

This evidentiary measure must be carefully prepared. The parties likely to be involved — seller, manufacturer, supplier, installer, repairer or insurer — should, if possible, be involved in the proceedings so that the findings are binding on them.

What legal recourse does the buyer have?

When a hidden defect is established, Article 1644 of the Civil Code offers the buyer two main options.

Request cancellation of the sale

The action for rescission allows the buyer to return the goods and obtain a refund of the price.

It can be adapted when the defect deprives the property of its essential utility or when its repair is impossible, uncertain or disproportionate.

However, restitution requires examining the conditions under which the property can be returned, as well as the consequences of its use, deterioration, or any transformations that may have been carried out since the sale.

Keep the item and get a price reduction

The price reduction action allows the buyer to keep the property while requesting a refund of part of the price.

The amount of the discount does not automatically correspond to the cost of repairs. It must reflect the difference between the value of the item as it was presented and its actual value taking the defect into account.

A technical or financial evaluation may therefore be necessary.

Obtaining damages and interest

The buyer may also claim compensation for damages caused by the defect when the legal conditions are met: diagnostic costs, immobilization of equipment, loss of operation, replacement costs, consequential material damages or other justified losses.

The extent of this compensation depends in particular on the seller's knowledge of the defect. Article 1645 of the Civil Code stipulates that a seller who was aware of the defect is obligated, in addition to refunding the price, to compensate the buyer for any damages caused.

The situation of the professional seller calls for particular vigilance, as case law imposes a particularly demanding liability regime on them due to their presumed competence.

What is the time limit for taking action under the warranty against hidden defects?

Article 1648 of the Civil Code provides that the action must be brought within two years from the discovery of the defect.

This starting point is therefore not necessarily the date of sale, delivery, or the first manifestation of an anomaly. It corresponds to the moment when the buyer had, or could have had, sufficiently certain knowledge of the defect, its seriousness, and its origin.

Depending on the circumstances, this knowledge may result from:

• of a technical diagnosis;
• of an amicable expert report;
• of the filing of a judicial expert report;
• from an intervention by the manufacturer;
• or elements clearly establishing the nature and extent of the defect.

The date of discovery is frequently disputed. It is therefore prudent not to wait for the conclusion of amicable discussions before taking the necessary steps to safeguard one's rights.

Can the two-year period be suspended or interrupted?

The Court of Cassation clarified that the two-year period provided for in Article 1648 of the Civil Code constitutes a limitation period, and not a period of preclusion.

This qualification is important: the deadline can, under certain conditions, be suspended or interrupted.

A legal claim, including an application for interim relief, can interrupt the statute of limitations. When a pre-trial investigative measure, such as a court-ordered expert assessment, is ordered, the suspension regime provided for in Article 2239 of the Civil Code may also apply.

However, it should not be assumed that an amicable claim, a formal notice, or simple negotiations automatically interrupt the statute of limitations. Each action must be analyzed in light of its nature and date.

Is there a maximum period of twenty years?

Yes. In several rulings issued by the combined chambers on July 21, 2023, the Court of Cassation clarified the relationship between the applicable time limits.

The action must be initiated within two years of the discovery of the defect, without exceeding the twenty-year time limit provided for in Article 2232 of the Civil Code.

This twenty-year period runs from the birth of the right, that is to say, in matters of warranty against hidden defects, from the sale concluded by the person against whom the action is brought.

The solution is particularly important in chains of contracts. When the final purchaser takes direct action against a previous manufacturer or seller, the starting point of the limitation period must be sought in the sale concluded by the latter, and not necessarily in the last sale made to the benefit of the final purchaser.

In practice, we must therefore consider two deadlines:

1. to act within two years of discovering the defect;
2. verify that the action is not barred by the twenty-year time limit running from the date of the sale concluded by the person being sued as guarantor.

Transitional rules may apply to older sales. A precise analysis of the contractual chronology remains essential.

Can the seller exclude the warranty against hidden defects?

The contract may contain a clause limiting or excluding the guarantee, but its effectiveness is not systematic.

Article 1643 of the French Civil Code stipulates that the seller remains liable for hidden defects, even if unaware of them, unless otherwise stipulated. An exclusion clause can therefore be effective in certain sales between private individuals.

However, it does not protect a seller who knew of the defect and concealed it. Its effectiveness is also very limited when invoked by a professional seller, particularly against a layperson or consumer.

In business-to-business relationships, the validity and scope of the clause depend in particular on their respective specialization, their level of competence, the drafting of the contract and the circumstances of the sale.

Warranty clauses, exclusion of liability clauses, and recourse clauses between professionals must therefore be examined from the outset of contract negotiations. ARST Avocats provides expertise in this area, specializing in contract law, distribution law, and franchise law.

Warranty against hidden defects and legal warranty of conformity: what's the difference?

These two guarantees should not be confused.

The warranty against hidden defects is provided for by the Civil Code and can apply to many sales, including between professionals or between individuals.

The legal guarantee of conformity falls primarily under consumer law. It protects consumers who purchase goods from a professional when the goods do not conform to the contract or to their normally expected use.

Their conditions, time limits, rules of evidence, and proposed remedies differ. Depending on the status of the parties and the nature of the defect, several legal bases may sometimes be considered: warranty against hidden defects, lack of conformity, breach of contract, fraud, or failure to disclose information.

The choice of legal basis must be made early enough, as it can determine the competent jurisdiction, the burden of proof, the claims that can be made and the deadlines to be met.

What should be done as soon as a defect is discovered?

The reaction adopted in the first few days can be decisive.

It is particularly recommended to:

• do not continue using the property if it risks aggravating the damage;
• avoid any irreversible repairs before the defect has been jointly verified;
• keep the replaced parts and hardware;
• to precisely date the first manifestations of the defect;
• gather the contractual and technical documents;
• inform the seller promptly;
• organize, if necessary, a contradictory expert assessment;
• identify all stakeholders and their insurers;
• Check the applicable deadlines immediately.

A formal notice may facilitate an amicable resolution, but it does not eliminate the need to ensure the statute of limitations is met. If there is a risk of the deadline expiring, legal action or evidentiary measures may need to be initiated without waiting for the outcome of negotiations.

Frequently asked questions about the warranty against hidden defects

How long do we have to take action in the event of a hidden defect?

The action must be initiated within two years of the discovery of the defect. In principle, it cannot be brought beyond the twenty-year limitation period running from the date of the sale concluded by the person being sued under the warranty.

Does a formal notice interrupt the limitation period?

A simple formal notice does not generally interrupt the statute of limitations on its own. It may be necessary to initiate legal proceedings, particularly summary proceedings, to effectively protect one's rights.

Is an expert assessment mandatory?

No, but it is often essential when the origin, pre-existing nature, or severity of the defect is disputed. The expert assessment should be conducted in an adversarial manner whenever possible.

Can we take action against the manufacturer?

In some sales chains, the end purchaser can take direct action against a previous manufacturer or seller. In such cases, each contract must be reconstructed, and the applicable time limits for each party being sued must be verified separately.

Can cancellation of the sale be combined with damages?

Additional compensation may be claimed when the legal conditions are met, particularly when the seller was aware of the defect. The alleged damages must be proven and must not lead to double compensation.
