Buying a property is often the project of a lifetime, but it can turn into a nightmare if serious defects appear after signing (cracks, hidden moisture, termites, damaged structural timber). In these situations, one immediately thinks of the legal warranty for hidden defects.

But what if the hidden defects claim is dismissed due to a procedural issue, or if the very short 2-year deadline is missed? Is it possible to sue the seller on the grounds of dol (intentionally deceiving the buyer by concealing a defect)?

This crucial question was answered by the Third Civil Chamber of the Court of Cassation in a major ruling on September 23, 2020 (Pourvoi No. 19-18.104).


The Facts: Selling a House with Concealed Defects

In 2006, a buyer purchased a house. During subsequent renovation work, she discovered serious structural defects. She decided to sue the seller under the warranty of hidden defects.

Unfortunately for her, her lawsuit was declared lapsed due to a procedural abandonment (péremption d'instance). Deprived of this option, the buyer decided to initiate a new claim, but this time on the grounds of tort liability for fraudulent concealment (dol). She claimed repair costs and damages for loss of enjoyment, demonstrating that the seller was fully aware of these defects and had intentionally concealed them during the sale.


The Legal Question: Does the Hidden Defects Action Exclude Fraud?

The Aix-en-Provence Court of Appeal rejected the buyer's claim. It held that the defects constituted redhibitory defects (vices cachés) and that the repair of such defects could only be requested under the action for warranty of hidden defects (Article 1641 of the Civil Code). According to the appellate judges, the hidden defects action was exclusive: it was impossible to sue on another basis for the same defects.

The buyer appealed to the Court of Cassation.


The Ruling: A Choice of Actions for the Buyer

The Court of Cassation overturned the court of appeal's judgment and laid down a rule of capital importance for the protection of buyers:

"The action under the warranty of hidden defects does not exclude a tort liability action based on fraud (dol)."

The high court clearly affirmed that the fact that a defect fits the definition of a hidden defect does not prevent the buyer from suing on the basis of fraud (general civil liability, Article 1240 of the Civil Code) if the seller committed an intentional fault by concealing the information.


Why This Ruling is a Victory for Buyers

This decision offers three major advantages for buyers of real estate or any other valuable asset:

  1. A longer time limit to act: An action under the hidden defects warranty must be initiated within a very strict limit of 2 years from the discovery of the defect. An action for liability for fraud, however, is prescribed by 5 years from the day the buyer discovered the deception (dol).
  2. Bypassing non-warranty clauses: Real estate sale contracts between private parties almost always contain a clause excluding the hidden defects warranty for non-professional sellers. In the event of fraud (intentional fault), a bad faith seller can never rely on this exclusion clause. It is declared void.
  3. Accumulate or choose damages: The buyer can claim full damages corresponding to repair costs without being forced to return the property (which is sometimes required in a classic redhibitory action).
