Almost every French property sale contract contains a line that foreign buyers from the United Kingdom, the United States or Australia tend to skim over: the property is sold en l’\u00e9tat<\/em> (in its current condition), with a clause de non-garantie des vices cach\u00e9s<\/a><\/em> (clause excluding the seller’s warranty for hidden defects). To a buyer raised on Anglo-Saxon conveyancing, the clause looks like the familiar “as-is” waiver. In French law it is something more subtle \u2014 and more dangerous to get wrong. The clause is real, it is enforceable, and in many cases it protects a private seller completely. But the Cour de cassation has spent the last three years drawing its exact boundaries, and those boundaries are not where most foreign buyers assume them to be.<\/p>\n This article explains what the no-warranty clause actually covers, which sellers can rely on it, when it collapses entirely, and what a non-resident buyer should do \u2014 before signing and after moving in \u2014 to avoid discovering, too late, that the house they bought “as-is” has no effective protection. It is based exclusively on the French Civil Code and on decisions of the Cour de cassation, all cited with their official links. It is written for buyers who are not familiar with French law, so the practical steps are set out in concrete terms.<\/p>\n French sale law starts from a strong default rule: the seller is liable for hidden defects. The clause de non-garantie<\/em> is the contractual exception to that rule, and its scope is defined by a handful of Civil Code articles and by a dense body of case law. Understanding the default rule first makes the exception intelligible.<\/p>\n The starting point is Article 1641 of the French Civil Code<\/a>, unchanged since 1804: “Le vendeur est tenu de la garantie \u00e0 raison des d\u00e9fauts cach\u00e9s de la chose vendue qui la rendent impropre \u00e0 l’usage auquel on la destine, ou qui diminuent tellement cet usage que l’acheteur ne l’aurait pas acquise, ou n’en aurait donn\u00e9 qu’un moindre prix, s’il les avait connus.” In plain English, the seller guarantees the property against hidden defects that make it unfit for its intended use, or that diminish that use to such a degree that the buyer would not have bought, or would have paid less, had he known of them. Three cumulative conditions are therefore required: the defect must be serious, it must be hidden, and it must pre-date the sale.<\/p>\n The second pillar is Article 1642<\/a>, which excludes apparent defects: “Le vendeur n’est pas tenu des vices apparents et dont l’acheteur a pu se convaincre lui-m\u00eame.” The seller is not liable for defects that are apparent and that the buyer could have discovered for himself. This article matters enormously in practice, because sellers routinely argue that the buyer saw the cracks, the damp patch or the sloping floor during the visits. Whether the buyer “could have convinced himself” of the defect and its true extent is a question of fact that the courts decide case by case, and the answers are frequently unfavourable to the seller.<\/p>\n The exception that makes the whole system negotiable is Article 1643<\/a>: “Il est tenu des vices cach\u00e9s, quand m\u00eame il ne les aurait pas connus, \u00e0 moins que, dans ce cas, il n’ait stipul\u00e9 qu’il ne sera oblig\u00e9 \u00e0 aucune garantie.” The seller is liable for hidden defects even if he did not know of them \u2014 unless, in that case, he stipulated that he would be bound by no warranty at all. That stipulation is the clause de non-garantie<\/em>, and it is the legal heart of every “as-is” sale in France. Its logic deserves to be stated plainly: a seller who did not know of the defect can exclude liability for it; a seller who knew of it cannot, because Article 1643 only authorises the clause “dans ce cas” \u2014 in the case where the seller was unaware.<\/p>\n When the warranty applies, Article 1644<\/a> gives the buyer the choice: “l’acheteur a le choix de rendre la chose et de se faire restituer le prix, ou de garder la chose et de se faire rendre une partie du prix” \u2014 either return the property and recover the full price (the action r\u00e9dhibitoire<\/em>, rescission) or keep it and obtain a partial refund of the price (the action estimatoire<\/em>, price-reduction action). And Article 1648<\/a> imposes a strict time limit: “L’action r\u00e9sultant des vices r\u00e9dhibitoires doit \u00eatre intent\u00e9e par l’acqu\u00e9reur dans un d\u00e9lai de deux ans \u00e0 compter de la d\u00e9couverte du vice.” The claim must be filed within two years of the discovery of the defect \u2014 discovery, not completion \u2014 and the courts have clarified, in rulings examined below, that the two-year period runs from the moment the buyer can understand the nature and origin of the defect, in practice often the date of the court-appointed expert’s report.<\/p>\n Two recent rulings illustrate how the mechanism operates in ordinary disputes. In Cass. 3e civ., 8 February 2023, no. 22-10.743<\/a> (published in the Bulletin), a buyer discovered that the floors of his flat were infested with wood-eating insects (insectes xylophages<\/em>) and claimed a price reduction against the seller. The seller’s answer was that the co-ownership had already repaired the defect, so the buyer had nothing left to claim. The Cour de cassation rejected that defence, ruling that only a repair performed by the seller himself, accepted by the buyer, extinguishes the statutory actions: “Cette solution ne peut pas \u00eatre \u00e9tendue \u00e0 la r\u00e9paration du vice cach\u00e9 par un tiers, laquelle, n’ayant pas d’incidence sur les rapports contractuels entre l’acqu\u00e9reur et le vendeur, ne peut supprimer l’action estimatoire.” A repair carried out by a third party \u2014 here the co-ownership syndicate \u2014 has no effect on the contractual relationship between buyer and seller, and does not remove the buyer’s right to a price reduction. For a foreign buyer, the practical lesson is that accepting someone else’s repair works, however well-intentioned, does not close the file against the seller.<\/p>\n The counterweight is Cass. 3e civ., 17 October 2024, no. 22-22.882<\/a>. A couple had bought a house whose acte authentique<\/em> (final notarial deed) contained a clause excluding the hidden-defects warranty. They later discovered major defects concerning, notably, the insulation and the energy performance of the property, and sued the sellers. The Cour de cassation confirmed that the sellers were private individuals \u2014 even though the husband worked as an estate agency negotiator \u2014 and that they could therefore rely on the exclusion clause. The Court noted that the purchase was “une op\u00e9ration isol\u00e9e de gestion de leur patrimoine priv\u00e9” \u2014 an isolated transaction in the management of their private assets \u2014 so the sellers were not professionals bound by the stricter regime. The case is a reminder that the clause works, and that it works against buyers too.<\/p>\n The no-warranty clause has a structural weakness: it only helps a seller who did not know of the defect. French law approaches the seller’s knowledge in two ways \u2014 direct proof and legal presumption \u2014 and both are applied strictly by the Cour de cassation.<\/p>\n The most important recent ruling on the presumption is Cass. 3e civ., 19 October 2023, no. 22-15.536<\/a> (published in the Bulletin). A SCI<\/a> (French property holding company) had sold a house that suffered from water leaks. The buyer invoked the hidden-defects warranty; the SCI answered with the no-warranty clause, and the Court of Appeal of Limoges dismissed the buyer’s claim on the ground that the seller had not been shown to know of the defect. The Cour de cassation quashed that decision. It recalled the settled rule in terms that are worth quoting in full: “le vendeur professionnel, auquel est assimil\u00e9 le vendeur qui a r\u00e9alis\u00e9 lui-m\u00eame les travaux \u00e0 l’origine des vices de la chose vendue, est tenu de les conna\u00eetre et ne peut se pr\u00e9valoir d’une clause limitative ou exclusive de garantie des vices cach\u00e9s.” A professional seller \u2014 and, crucially, any seller who carried out the works that caused the defects \u2014 is presumed to know of them and cannot rely on an exclusion clause. The appeal court should therefore have examined whether the SCI had built the house’s extension itself through its manager, without hiring a professional builder, before accepting the clause. The ruling reaches far beyond companies: any private owner who had building works done, or did them himself, before selling can be treated as a “professional” for the purpose of the warranty, no matter how amateur the works were.<\/p>\n The second ruling, Cass. 3e civ., 23 October 2025, no. 23-18.469<\/a> (with joined appeals nos. 23-18.508 and 23-18.560), draws the mirror-image boundary: the clause is opposable to a professional buyer of the same speciality. The seller Gecina, a professional property company, had sold an office building to a property investment vehicle (a SCPI); the diagnostics annexed to the deed wrongly stated that the building contained no asbestos. When asbestos was discovered, the buyer claimed against the seller on the hidden-defects warranty. The Cour de cassation quashed the decision that had set the exclusion clause aside, recalling that “la clause limitative ou exclusive de garantie des vices cach\u00e9s est opposable \u00e0 un acheteur professionnel de m\u00eame sp\u00e9cialit\u00e9 que celui qui lui vend la chose” \u2014 the exclusion clause is enforceable against a professional buyer of the same speciality, unless the buyer proves the seller had effective knowledge of the defect (bad faith). The appeal court should have investigated whether the buyer, despite being a professional, had the same speciality as the seller \u2014 a SCPI investing in rental property is not necessarily a specialist in asbestos detection. The practical significance for foreign buyers is symmetrical to the 2023 ruling: the courts look at the actual capacity of each party, not at labels. A foreign buyer who invests through a company, or who is himself a property professional, may find the clause enforced against him more easily than a purely private purchaser would.<\/p>\n A third ruling, Cass. 3e civ., 14 September 2023, no. 22-16.623<\/a>, shows how seller knowledge can be established from the everyday circumstances of ownership. Sellers who had lived in their house for twenty years sold it with a no-warranty clause; the buyers later discovered that the cracks in the walls and the pool were caused by foundations unsuited to the soil. The Cour de cassation upheld the Court of Appeal’s finding that the sellers were in bad faith and could not rely on the clause. The evidence was circumstantial but overwhelming: the sellers had occupied the property for twenty years and had necessarily witnessed the appearance of progressive cracks; their insurer had told them, in response to a claim made around 2000, that the cracks were of a ten-year-liability nature; and their own title deed informed them that a ten-year liability claim was pending against the original builder. The ruling also rejected the sellers’ argument that the cracks were apparent to the buyers: the buyers had seen traces of repairs on the facades, but “ils ne pouvaient, n’\u00e9tant ni des professionnels du b\u00e2timent ni tenus de se faire accompagner par un homme de l’art, se convaincre du vice dans son ampleur et ses cons\u00e9quences” \u2014 being neither building professionals nor obliged to bring in a technical expert, they could not satisfy themselves of the defect’s full scope and consequences. Three practical lessons flow from this for a non-resident buyer: ask how long the seller has occupied the property, ask whether any insurance claim was ever made on it, and understand that a few visible signs do not turn a hidden defect into an apparent one.<\/p>\n The cases examined so far show the clause at work in the abstract. In practice, the disputes that reach the Cour de cassation turn on evidence: what the seller knew, what he did about it, and what he failed to disclose. This second part sets out the concrete situations in which the clause fails, and the steps a foreign buyer should take before and after completion.<\/p>\n The seller’s knowledge can be proved directly, and the courts draw it from documents that often pre-date the sale: insurance claim files, expert reports, correspondence with builders, and municipal records. Three rulings from 2023 to 2025 define the evidentiary rules that matter most.<\/p>\n The first is Cass. 3e civ., 7 March 2024, no. 20-17.790<\/a>. Sellers in Noisy-le-Grand (Seine-Saint-Denis) sold a house for \u20ac325,000 after filling in the cracks on its facades and applying a fresh coat of render. The buyers discovered that the house was riddled with cracks linked to the clay soil and to subsidence repairs carried out in 1980. The Cour de cassation upheld the award against the sellers of \u20ac202,267.20 by way of price reduction, plus \u20ac7,800 in damages. The decisive finding was that “les vendeurs, qui connaissaient les probl\u00e8mes de structure de l’immeuble depuis 1980 ainsi que l’ampleur des fissurations r\u00e9apparues en 2003, avaient, par ces travaux de colmatage, cherch\u00e9 \u00e0 les dissimuler” \u2014 the sellers, who had known of the structural problems since 1980 and of the extent of the cracks that reappeared in 2003, had sought to conceal them through those filling-in works. Cosmetic works carried out shortly before a sale \u2014 repointing, re-rendering, painting over damp, replacing a section of roof \u2014 are the single most dangerous red flag in French property law: they are simultaneously evidence that the seller knew, and evidence of concealment, which is bad faith. The exclusion clause was set aside, and the sellers were ordered to pay \u20ac3,000 under Article 700 of the Code of Civil Procedure on top of the principal award. For a foreign buyer, the checklist is obvious: obtain from the seller the history of works, ask the neighbours or the town hall about recent building activity, and treat a freshly rendered facade as a question, not an aesthetic improvement.<\/p>\n The second ruling is Cass. 3e civ., 5 June 2025, no. 23-14.619<\/a>, which involved the seller’s insurance file. The seller had had her house built in 1998 and sold it in 2014 with a no-warranty clause. Eight years before the sale, she had reported a claim to the developer’s insurer concerning rising damp and infiltrations in the basement. The insurer had described the damage as purely aesthetic and had refused cover, and the Court of Appeal of Paris concluded that the seller had not known of any hidden defect. The Cour de cassation quashed that decision. It recalled the principle in terms that now appear in many judgments: “Le vendeur qui, ayant connaissance d’un vice lors de la conclusion du contrat, stipule qu’il ne le garantira pas, est tenu \u00e0 garantie, nonobstant cette clause.” A seller who knows of a defect at the time of signing and nonetheless stipulates that he will not warrant it remains bound by the warranty, notwithstanding the clause. And it pointed out the factual error that had poisoned the appeal judgment: the insurance expert had not only found the aesthetic staining, but also actual water infiltrations in works that the seller herself had carried out \u2014 works that were not covered by the builder’s insurance. The seller therefore knew of infiltrations that were never characterised as aesthetic. The lesson is a striking one for buyers: an insurance claim file that precedes the sale can be decisive evidence of the seller’s knowledge, even when the insurer refused to pay. When you buy a property in France, ask \u2014 through your notaire<\/em> (French notary, the public officer who drafts and secures the deed) \u2014 for any past insurance claims, and check whether the seller ever notified damage to an insurer or a builder.<\/p>\n The third ruling completes the picture: Cass. 3e civ., 1 March 2023, no. 21-25.315<\/a>. A seller in the Maine-et-Loire had, in 2008, built a contre-mur<\/em> (counter-wall) on the neighbour’s land to prop up an old and cracked schist wall on which the house’s extension rested. The sale deed said nothing about these recent works. The buyers discovered the fragility of the whole structure and sued. The seller invoked both the no-warranty clause and the argument that the works had actually strengthened the building. The Cour de cassation rejected the appeal: the counter-wall had been erected to hold up an old structure “dont la fragilit\u00e9 \u00e9tait d\u00e9nonc\u00e9e depuis longtemps par les anciens propri\u00e9taires” \u2014 whose fragility had long been denounced by previous owners \u2014 and the seller, who had ordered the works, could not ignore that fragility, so the no-warranty clause was set aside. Two points matter here. First, knowledge is often obvious to the seller even when it is invisible to the buyer: whoever orders structural works knows why they are needed. Second, the works had been carried out on the neighbour’s land, outside the plot sold \u2014 a fact the buyer had no reason to discover, which made the defect invisible to him. The case is a useful warning for buyers of houses with recent structural additions: a supporting wall, tie rods or underpinning are signs of a structural past, and silence about them in the deed is not protection for the seller.<\/p>\n The no-warranty clause has a second structural weakness, distinct from bad faith: it only covers the physical condition of the property. It does not cover legal burdens on the land, and a recent published ruling makes that limit explicit.<\/p>\n In Cass. 3e civ., 13 February 2025, no. 23-17.636<\/a> (published in the Bulletin), a buyer discovered beneath her house a sewage pipe network that had not been mentioned in the sale deed, and sued the sellers under the warranty for undisclosed encumbrances. The deed contained a sweeping as-is clause: the buyer took the property “dans l’\u00e9tat o\u00f9 il se trouve”, with no recourse “pour quelque cause que ce soit, notamment en raison : des vices apparents, des vices cach\u00e9s” \u2014 no recourse for any reason whatsoever, including apparent and hidden defects. The Court of Appeal of Agen held that such a clause, applying “for any reason whatsoever”, excluded the claim. The Cour de cassation quashed the decision. It relied on Article 1638 of the Civil Code<\/a>: “Si l’h\u00e9ritage vendu se trouve grev\u00e9, sans qu’il en ait \u00e9t\u00e9 fait de d\u00e9claration, de servitudes non apparentes, et qu’elles soient de telle importance qu’il y ait lieu de pr\u00e9sumer que l’acqu\u00e9reur n’aurait pas achet\u00e9 s’il en avait \u00e9t\u00e9 instruit, il peut demander la r\u00e9siliation du contrat, si mieux il n’aime se contenter d’une indemnit\u00e9.” If the land sold is burdened, without any declaration, by hidden servitudes<\/em> (easements) of such importance that the buyer would presumably not have bought had he known, he may claim rescission or an indemnity. The Court held that this warranty for hidden easements is an application of the general warranty against eviction, which protects the buyer’s peaceful possession \u2014 a matter entirely distinct from the intrinsic condition of the property. An as-is clause, even one drafted “for any reason whatsoever”, “propre \u00e0 l’\u00e9tat du bien” (specific to the condition of the property), does not exclude it. In practice this means: hidden easements, undisclosed rights of way, and unregistered pipes or cables are not covered by the no-warranty clause. A foreign buyer who discovers such a burden may still act, regardless of the clause, and the title search carried out by the notary before completion is the first line of defence.<\/p>\n Two further practical layers complete the picture for a buyer who discovers defects after an as-is purchase. First, the diagnostics file. Under Article L. 271-4 of the French Construction and Housing Code<\/a>, the seller must annex a technical diagnostics file to the preliminary sale agreement, and the courts have given the buyer direct remedies against the diagnostiqueur<\/em> (the certified technician who drew up the reports) when a report is wrong. The October 2025 ruling in the Gecina case is instructive here: the Cour de cassation held that when a diagnostic erroneously certified the absence of asbestos, the buyer’s loss is not merely a lost opportunity to negotiate a lower price, but the full cost of the asbestos removal works (“un pr\u00e9judice certain \u00e9quivalent au surco\u00fbt des travaux de d\u00e9samiantage”). Even where the as-is clause blocks the claim against the seller, a buyer may still have an actionable claim against the diagnostiqueur \u2014 a route that does not exist in most common-law systems and that foreign buyers should not overlook.<\/p>\n Second, the mandatory declarations and the two-year clock. The seller’s knowledge is often documented in the very papers of the sale: the natural-risks statement, the past insurance claims, the declarations in the deed. Keep every one of them, plus all pre-sale correspondence and photographs. If defects appear, act within the two-year period of Article 1648, which runs from discovery \u2014 and consult a lawyer before the year is out, because assembling evidence, obtaining a expertise judiciaire<\/em> (court-ordered expert report) and filing the claim takes time, and because the courts date discovery from the moment the buyer could understand the nature and origin of the defect, which is usually the expert’s report. As to the tax consequences of a price reduction or rescission \u2014 which may affect your capital gains position in your country of residence \u2014 they fall outside the scope of this article and should be reviewed with your tax adviser.<\/p>\n For a non-resident buyer, the practical sequence is therefore: (i) before signing, read the as-is clause and understand exactly what it excludes, and ask the notary to confirm in writing that the title search and the diagnostics file are complete, including any past insurance claims of the seller; (ii) before completion, visit the property with a technical expert if the house has any recent cosmetic works, structural additions or signs of repairs, and put every question in writing; (iii) after completion, keep the full file and act without delay if a defect appears; and (iv) where the seller is a professional, a builder, or a seller who did the works himself, remember that the clause may be worthless against him. A lawyer specialising in French real estate law, such as the real estate team at Kohen Avocats in Paris<\/a>, can review the sale file before you commit and, if defects emerge later, assess whether the no-warranty clause holds or fails against the facts.<\/p>\n The as-is clause of French sale law is not a trap set for foreign buyers, but it is a contract term whose real content most buyers misunderstand. It protects a good-faith private seller who did not know of the defect \u2014 that is the meaning of Article 1643 and of the October 2024 ruling in no. 22-22.882. It fails against a seller who knew, who concealed, or who built: knowledge is proved from insurance files, works history and the seller’s own occupation of the property, as shown by the rulings of 7 March 2024, 5 June 2025 and 1 March 2023; and it is presumed against professionals and against sellers who carried out the works at the origin of the defects, under the published ruling of 19 October 2023. It is enforced against professional buyers of the same speciality, as the October 2025 asbestos ruling confirms. And it never covers what it cannot see: hidden easements and undisclosed legal burdens remain warranted under Article 1638 even in the face of an “as-is” clause, as the published ruling of 13 February 2025 establishes.<\/p>\nI.
