Imagine you own a beautiful apartment in Cannes, facing the sea. You checked everything before the purchase: the condition of the walls, plumbing, electricity. Yet, six months after moving in, cracks suddenly appear on the load-bearing walls. An expert reveals a foundation defect dating from the construction, invisible during your visit. You have comprehensive home insurance, you think you're covered. But what is the reality?
I encounter this situation regularly in my practice in the Grasse jurisdiction, whether in Cannes, Antibes, or the perched villages of the hinterland. Property owners, tenants, or even real estate professionals often ask the same question: does my insurance cover problems related to hidden defects (defects invisible at the time of acquisition)?
The decision of the Court of Cassation of 10 September 2015 provides a clear answer, but one that may surprise. It reminds us of a fundamental rule of insurance law that many are unaware of, with concrete consequences for your assets. Without saying too much for now, know that this decision could well change the way you read your insurance contracts.
The Facts: A Story That Happens Every Day
Take the example of Mr. Martin, whom I'll call that to preserve anonymity, but whose case resembles many files I handle. Mr. Martin, residing near Antibes, had purchased a used car in 2008. Like any prudent motorist, he had taken out comprehensive insurance with Icare Assurance. He thus thought he was protected against the hazards of the road.
On 21 January 2009, while driving on the Promenade des Anglais in Nice, his car broke down suddenly. The garage diagnosed a serious problem: a defect in the assembly of the crankcases (the engine casings), present since the vehicle's manufacture but invisible at the time of purchase. In legal terms, this is a hidden defect (a defect that renders the item unfit for its normal use, existing before the sale and not detectable by a careful examination).
Mr. Martin naturally turns to his insurer, thinking his contract covers this type of damage. But Icare Assurance refuses to cover the repairs, arguing that hidden defects are not guaranteed. Disappointed and facing a bill of several thousand euros, Mr. Martin decides to take legal action.
The case follows the classic judicial path: first the tribunal, then the court of appeal. The appeal judges, examining the file, indeed find that the damage was caused by a hidden defect predating the sale. They consider that the insurer must guarantee this damage and order Icare Assurance to compensate Mr. Martin. The insurer, dissatisfied with this decision, files an appeal to the Court of Cassation. This is where the case takes a decisive turn.
The Court's Reasoning — Analysed
The Court of Cassation, the highest French judicial court, examines the appeal with characteristic rigour. Its reasoning is based on a precise text: Article L. 121-7 of the Insurance Code. But what exactly does this article say?
Article L. 121-7 of the Insurance Code provides that, in damage insurance (contracts guaranteeing the repair of material loss), the insurer only guarantees the hidden defect of the insured item if the contract expressly provides for it. In other words, the default rule is exclusion: unless there is a clear contrary mention in your insurance policy, hidden defects are not covered.
The Court of Cassation applies this principle to Mr. Martin's case. It notes that the appeal judges correctly held that the damage was due to a hidden defect (the assembly defect of the crankcases). But it especially observes that the insurance contract taken out by Mr. Martin did not contain any clause expressly covering hidden defects. It was not enough that the contract did not explicitly exclude this guarantee; it had to include it clearly and precisely.
Consequently, the Court of Cassation quashes (annuls) the appeal court's judgment. It considers that the latter violated Article L. 121-7 of the Insurance Code by ordering the insurer to guarantee a hidden defect when the legal exclusion (the fact that the law provides that this is not covered by default) had not been expressly set aside by the contract. This reasoning confirms consistent case law: the burden of proof lies with the insured to demonstrate that their contract specifically covers hidden defects.
undefined, I have encountered cases where property owners in Cannes thought they were covered for water infiltration due to hidden construction defects, only to discover that their home insurance mentioned nothing on this subject. This Court of Cassation decision serves as a reminder of this often-unknown reality.
What This Means for You — Concretely
But what exactly does this change in your life as a property owner, tenant, or real estate professional? The implications are significant and vary depending on your situation.
If you are a landlord (person who lets a property): imagine you let an apartment in Antibes with a terrace. One year after the tenancy begins, the terrace shows cracks due to a construction defect invisible at the time of purchase. Your non-occupier owner's insurance (the one covering properties you let) will not cover the repairs if the contract does not explicitly provide for the guarantee of hidden defects. You will then have to seek recourse against the seller or builder, which can be lengthy and costly. In a recent case in Antibes, I saw repairs of this type reach €15,000 to €20,000.
If you are a tenant: your home insurance (mandatory) generally covers your civil liability and personal belongings, but not the hidden defects of the dwelling itself. If your plumbing fails due to a hidden defect, it is up to the owner to invoke their decennial guarantee (the builder's legal guarantee for 10 years) or their own insurance, if it provides for it. But be careful: if the owner is not covered, tensions can rise quickly.
If you are a property purchaser: when buying a house in Grasse, you benefit from the seller's guarantee against hidden defects (Article 1641 of the Civil Code). But this guarantee is distinct from your insurance. If you discover a hidden defect after purchase, you have two years to take action against the seller, but your insurance will not necessarily help you. What few people know is that certain specific insurances (like construction damage insurance) can cover these risks, but they must be taken out separately.
If you are a co-owner: in a co-ownership, hidden defects of the common parts (like a roof defect) fall under the decennial guarantee if the building is less than 10 years old, or the building's insurance. But again, check if the building's contract expressly includes hidden defects. In a co-ownership in Cannes, I saw a management association have to undertake €50,000 worth of work for infiltration due to a hidden defect, without insurance coverage, because the contract was silent on this point.
In short, this decision requires you to be proactive: you must check your insurance contracts and, if necessary, negotiate a hidden defect guarantee clause. The time limits for action are short: generally 2 years for the hidden defect guarantee against the seller, and variable contractual deadlines for insurance.
Four Tips to Avoid This Type of Dispute
- Read your insurance contract carefully before signing: specifically look for mentions of "hidden defect", "construction defect", or "hidden defect guarantee". If these terms do not appear, consider that you are not covered. Do not rely on verbal assurances from your broker.
- Request a guarantee extension in writing: if you wish to be covered for hidden defects, demand an explicit additional clause in your insurance policy. This clause should specify the conditions and limits of the guarantee (for example, a compensation cap).
- Have a thorough diagnostic survey carried out before any purchase: for a property, call on an independent expert who can detect potential hidden defects. In Antibes, for example, a structural survey costs between €800 and €1,500, but can save you tens of thousands of euros in repairs.
- Keep all your documents: retain insurance contracts, expert reports, purchase invoices, and correspondence with sellers or insurers. In case of dispute, this evidence will be crucial to defend your rights.

Further Insight: Related Case Law and Developments
The 2015 decision fits into consistent case law of the Court of Cassation. Already in 2007 (judgment No. 06-10.305), the Court had reminded that Article L. 121-7 of the Insurance Code requires an express mention to cover hidden defects. This position is firm and has not evolved recently.
On the other hand, there is a trend for courts to interpret exclusion clauses in insurance contracts strictly. For example, in a 2018 decision of the Paris Court of Appeal, the judges refused to allow an insurer to invoke an overly general exclusion to avoid its guarantee. But for hidden defects, the rule remains clear: no express mention, no coverage.
What does this mean for the future? Insurers might be encouraged to offer more optional guarantees for hidden defects, but at an additional cost. For consumers, vigilance remains essential. How to react? By being informed and negotiating your contracts.
