Latent Defect: The Seller in Good Faith Only Refunds the Price, Not the Cost of Repairs

You have just bought a house in Tarnos, near Mont-de-Marsan, and discover that termites have eaten away the roof timbers. The repair costs are estimated at €30,000. You turn to the seller, but he swears he was not aware of it. Can he be forced to pay for the repairs? The answer from the Court of Cassation, in a judgment of 8 April 2009, is clear: no. The seller in good faith must only refund a portion of the sale price, not the cost of remedial works. But how is this restitution calculated? And what remedies do you have? Analysis.

The Facts: A Story That Happens Every Day

Mr X, owner of a house in Biscarrosse, sells it to Mr Y. Shortly after the sale, Mr Y discovers that the house is infested with termites. He commissions an expert report which reveals that the insects have caused significant structural damage. Mr Y then sues Mr X before the court, seeking, on the basis of the warranty against latent defects (Articles 1641 et seq. of the Civil Code), reimbursement of the sale price and payment of the repair costs, totalling €30,500. The contract of sale contains a clause excluding the warranty against latent defects, but the seller is considered to be in bad faith because he was aware of the defect. At first instance, the court orders Mr X to pay €30,500. Mr X appeals, but the Court of Appeal upholds the decision. He then appeals to the Court of Cassation. The Court of Cassation quashes the decision: it finds that Mr X was in good faith (he was unaware of the defect) and that the exclusion clause was valid. Consequently, the seller must only return a portion of the price, not the cost of the works.

The Reasoning of the Court — Explained

The Court of Cassation relies on Article 1643 of the Civil Code, which provides that the seller is liable for latent defects even if he was unaware of them, unless there is a contrary clause. However, if the contract contains a clause excluding the warranty (as was the case here), the seller in good faith is not liable for damages. On the other hand, he must refund a portion of the price, because the property was not as promised. The amount of this restitution is determined by an expert, based on the diminution in value caused by the defect, not the cost of repairs. In other words, if the house is worth €200,000 without termites and €150,000 with them, the seller must reimburse €50,000, even if the repairs cost €30,000. The Court therefore censures the Court of Appeal, which had awarded the cost of the works. This reasoning confirms consistent case law: the purpose of the warranty against latent defects is not to finance repairs, but to restore the balance of the contract. However, beware: if the seller is in bad faith (he knew about the defect), he must compensate all damages, including the cost of repairs.

What This Means for You — Concretely

This decision has major implications for buyers and sellers. If you are a buyer: you cannot require the seller in good faith to pay for repairs. You will only recover a portion of the price, assessed by an expert. For example, if you bought a villa in Biscarrosse for €250,000 and the termites cause a diminution in value of €40,000, the seller will reimburse you €40,000, even if the repairs cost €60,000. If you are a seller: if you were unaware of the defect, you are protected against excessive claims. However, you must refund a portion of the price, which can be burdensome. It is therefore better to have the property inspected before the sale. For professionals: developers, estate agents, notaries, this case law recalls the importance of technical diagnostics. A notary who fails to draw attention to an exclusion of warranty clause may be liable for breach of duty to advise.

Four Tips to Avoid This Type of Dispute

• Have a termite inspection carried out before the sale: mandatory in risk areas such as the Landes, it allows the defect to be detected and the buyer to be informed. This protects you as a seller.
• Negotiate a warranty against latent defects clause: if you are a buyer, insist that the contract does not contain an exclusion clause. Otherwise, you lose all recourse against the seller in good faith.
• Keep all documents relating to the maintenance of the property: invoices for works, expert reports, etc. In case of dispute, they can prove whether the seller knew or did not know of the defect.
• Consult a lawyer lawyer as soon as the defect is discovered: time limits are short (two years from discovery of the defect to bring legal proceedings). A lawyer can assess the strength of your case and advise you on the next steps.

Further Analysis: Related Case Law and Developments

This decision is part of a consistent line of authority from the Court of Cassation. For example, in a judgment of 17 January 2006 (No. 04-10.931), it had already held that the seller in good faith need only refund the price, not the cost of repairs. More recently, the Court clarified that the partial refund of the price is calculated by reference to the market value of the property without the defect, not the cost of repairs (Civ. 3e, 10 Sept. 2015, No. 14-17.074). The trend is therefore protective of sellers in good faith, but buyers are not without recourse: they can sue the notary for breach of duty to advise, or the estate agent for failure to provide information. In practice, the courts are increasingly demanding on the proof of the seller's good faith. A seller who had renovation works carried out shortly before the sale may be presumed to have known of the defect.
