Recent court decision in real estate law: hidden defects and the protection of the purchaser

Real estate law is an area of civil law particularly rich in litigation, notably due to the complexity of transactions and the multiplicity of stakeholders. Among the recurring issues faced by both individuals and professionals, the question of hidden defects occupies a central place. A recent court decision perfectly illustrates the issues and consequences of a dispute concerning the discovery of a hidden defect after the sale of a property, highlighting the protection of the buyer, the obligations of the seller, and the subtleties of proof.

I. The context: real estate sales and the concept of hidden defects

The sale of real estate is a major legal transaction, which involves the seller's liability towards the buyer. According to the Civil Code, the seller is required to guarantee the buyer against hidden defects in the property sold, i.e. against defects not apparent at the time of sale that render the property unfit for its intended use, or that so diminish this use that the buyer would not have acquired it, or would have paid a lower price for it, if they had been aware of them.1.

The concept of hidden defect therefore presupposes three conditions:

• The defect must be hidden, i.e. not apparent at the time of sale.

• It must make the property unfit for use or significantly reduce its use.

• It must be prior to the sale, even if it only appears after the acquisition1.

Typical examples: structural moisture problems, a framework infested with dry rot, defective foundations or water infiltration not detected during visits.

II. Jurisprudential illustration: the recent decision on hidden defects

A. The facts giving rise to the dispute

In a recent case, a buyer discovered significant moisture and mold problems a few months after purchasing his house. An expert report revealed that the origin of the problem was a defect in the foundations, dating back to the construction of the property. The buyer, believing that this defect was hidden and predated the sale, took legal action against the seller, seeking either the cancellation of the sale or a reduction in the price.1.

B. The parties' arguments

• The purchaser invokes Article 1641 of the Civil Code, asserting that the defect was not apparent, serious, and prior to the sale. He maintains that he would never have purchased the property at that price if he had been aware of the defect.

• The seller defends himself by claiming that he was unaware of the defect and that, at the time of the sale, there was no indication of such a problem. He also argues that the buyer should have had a more in-depth appraisal carried out before the purchase.

C. The court's decision

The court points out that the warranty against hidden defects applies even if the seller was unaware of the existence of the defect, unless it is a non-professional seller who has inserted a valid exemption clause. In this case, proof of the prior existence of the defect is provided by the expert report, and the hidden nature of the defect is established: the traces of humidity were not visible during the visits, and the underlying cause (poor foundation work) could not be detected without a technical investigation.

The court therefore orders the seller to compensate the purchaser, by granting him a reduction in the sale price corresponding to the loss in value of the property, or even, in certain cases, the outright cancellation of the sale.1.

III. Lessons from the decision

A. The burden of proof and the role of expertise

One of the main difficulties for the buyer is to provide proof that the defect existed before the sale. In most cases, this requires a legal expert appraisal, which alone can determine the origin and age of the defect.1. This requirement for proof protects the seller against unfounded accusations, but it can also constitute an obstacle for the buyer, particularly due to the cost and duration of the procedures.

B. Limits of the warranty: normal wear and tear and subsequent damage

Not all defects constitute hidden defects. The following are excluded:

• Damage caused by the purchaser after the sale (for example, a water leak due to work poorly carried out by the new occupant).

• Natural phenomena occurring after the sale, not linked to a previous defect.

• Normal wear and tear of aging equipment (for example, a boiler that breaks down after several years of use)1.

C. The scope of the exemption clause

It is common for real estate sales contracts to include a clause disclaiming the warranty against hidden defects, especially when the seller is an individual. However, this clause does not protect the seller in the event of fraud, i.e. if the seller has deliberately concealed a defect of which he was aware. However, proof of fraud is difficult to provide and requires establishing that the seller knew, at the time of the sale, that the defect existed and that he knowingly failed to disclose it to the buyer.2.

IV. Practical consequences for the parties

A. For the purchaser

• Increased vigilance when purchasing : it is advisable to have in-depth diagnostics carried out, particularly if there is any doubt about the condition of the property (humidity, roof, foundations, etc.).

• Responsiveness in the event of discovery of a defect : the law requires the purchaser to act within a relatively short period (two years from the discovery of the defect, according to article 1648 of the Civil Code).

• Possibility of appeal : in the event of a proven hidden defect, the purchaser may request either the cancellation of the sale (redhibitory action), or a reduction in the price (estimated action), or damages in the event of fraud.

B. For the seller

• Obligation to provide information : the seller must inform the buyer of any known defect, otherwise he will be held liable.

• Limits of liability : the inclusion of an exemption clause can protect the non-professional seller, except in cases of fraud.

• Litigation risks : even in good faith, the seller can be prosecuted if a hidden defect is discovered, hence the interest in having diagnostics carried out before the sale and keeping a written record of the information transmitted to the buyer.

V. Related issues in real estate law

A. Other causes of real estate disputes

In addition to hidden defects, many other disputes can arise during a real estate transaction:

• Material defects or damage (plumbing, electricity, roofing, etc.)3.

• Defects of consent (deception, pressure, error on an essential element of the contract)32.

• Zoning and local regulation issues (land use, building permits denied, etc.)3.

• Failure to comply with co-ownership rules (unauthorized work, unpaid charges, etc.)3.

• Disputed easements and rights of way3.

B. Limitation of actions

The statute of limitations is a key element in real estate law. For hidden defects, the action must be brought within two years of the discovery of the defect (Art. 1648 C. civ.), but this period can be extended in the event of proven fraud (up to ten years).2.

VI. The impact of the decision on notarial practice and the security of transactions

This recent decision highlights the importance for notaries and real estate professionals of securing transactions:

• Precise drafting of contracts : explicitly mention the condition of the property, the diagnostics carried out, any reservations the purchaser may have.

• Advice to the parties : inform sellers and buyers of the risks and possible remedies in the event of subsequent discovery of a defect.

• Dispute management : support clients in the amicable resolution of disputes, or, failing that, in legal proceedings.

VII. Conclusion: a case law that protects the purchaser, but is demanding on proof

The recent court decision regarding hidden defects in real estate confirms the courts' desire to protect buyers against serious and hidden defects, while imposing a strict burden of proof. It illustrates the need for each party to act with diligence, transparency, and prudence when selling or purchasing real estate.

Ultimately, while the law offers the purchaser effective tools to obtain compensation in the event of a hidden defect, the fact remains that prevention, information and support from competent professionals remain the best ways to avoid the long and costly disputes that too often plague the real estate sector.4132.

"The defect must exist at the time of the sale, even if it only became apparent after the acquisition. Proof of this precedence lies with the purchaser, which can be complex without a thorough expert appraisal."1

This overview highlights a concrete and frequent problem in real estate law, illustrated by a recent court decision, and offers a detailed analysis of the issues, solutions and best practices to adopt to secure transactions and protect everyone's rights.
