Imagine purchasing a house in Provence, only to discover after signing the deed that the seller deliberately concealed the fact that the next-door neighbour has a history of violent behaviour, or that the property is subject to a flood risk the vendor knew about but never disclosed. For foreign buyers\u2014whether from the United Kingdom, the United States, or Australia\u2014the French legal system provides a powerful remedy: dol<\/em> (fraudulent misrepresentation). And as of May 2026, the French Cour de cassation has significantly strengthened that remedy by reinstating the possibility of recovering the exc\u00e8s de prix<\/em> (excess price) as a distinct head of damage. This article explains how the law of dol works, what obligations sellers owe to buyers under French law, and what practical steps a foreign purchaser can take to protect their investment.<\/p>\n French property transactions are already complex for the international buyer: the compromis de vente<\/a><\/em> (preliminary sale agreement), the mandatory diagnostic reports, the notarial process, and the unique French concept of vices cach\u00e9s<\/a><\/em> (hidden defects) all differ significantly from Anglo-Saxon conveyancing. When deception is layered onto that complexity, the consequences can be severe. The good news is that French courts\u2014particularly the Third Chamber of the Cour de cassation<\/a>, which handles property disputes\u2014have steadily refined the tools available to buyers. The 28 May 2026 ruling marks a decisive step forward.<\/p>\n Under French law, dol<\/em> is a defect of consent (vice du consentement<\/em>) that can render a contract voidable. The definition is set out in article 1137 of the Code civil<\/a>: \u00ab Le dol est le fait pour un contractant d\u2019obtenir le consentement de l\u2019autre par des man\u0153uvres ou des mensonges. Constitue \u00e9galement un dol la dissimulation intentionnelle par l\u2019un des contractants d\u2019une information dont il sait le caract\u00e8re d\u00e9terminant pour l\u2019autre partie. \u00bb In English: dol is the act by which one contracting party obtains the other\u2019s consent through manoeuvres or lies. It also includes the intentional concealment by one party of information they know to be decisive for the other party.<\/p>\n This definition is crucial for foreign buyers because it captures not only affirmative lies but also r\u00e9ticence dolosive<\/em> (fraudulent concealment)\u2014the deliberate failure to disclose a material fact. For a seller to be liable, three conditions must be satisfied: (1) the information concealed must have been decisive (d\u00e9terminant<\/em>) for the buyer\u2019s decision; (2) the seller must have known the information; and (3) the concealment must have been intentional. The Cour de cassation emphasised in Cass. 3e civ., 21 November 2024, no. 23-10.180<\/a> that for r\u00e9ticence dolosive to be established, the seller\u2019s silence must have been intentional\u2014mere negligence does not suffice. In that case, the court overturned an appellate decision that had found dol where the seller honestly believed that earlier structural reinforcement works had resolved the problem. As the ruling states, the appellate court had relied on grounds \u00ab impropres \u00e0 \u00e9tablir le caract\u00e8re intentionnel du d\u00e9faut d\u2019information de l\u2019acqu\u00e9reur \u00bb (unsuitable to establish the intentional character of the failure to inform the buyer).<\/p>\n This distinction is important in practice: if a seller genuinely did not know about a defect, dol cannot be invoked. However, the buyer may still have recourse under the separate regime of garantie des vices cach\u00e9s<\/em> (the warranty against hidden defects), governed by article 1641 of the Code civil<\/a>: \u00ab Le vendeur est tenu de la garantie \u00e0 raison des d\u00e9fauts cach\u00e9s de la chose vendue qui la rendent impropre \u00e0 l\u2019usage auquel on la destine, ou qui diminuent tellement cet usage que l\u2019acheteur ne l\u2019aurait pas acquise, ou n\u2019en aurait donn\u00e9 qu\u2019un moindre prix, s\u2019il les avait connus. \u00bb That is: the seller is bound to guarantee against hidden defects of the thing sold which render it unfit for its intended use, or which so diminish that use that the buyer would not have purchased it, or would have paid a lower price, had they known.<\/p>\n Another scenario where dol can arise was illustrated by a more unusual case in 2023. In Cass. 3e civ., 16 March 2023, no. 21-23.702<\/a>, the Cour de cassation held that a public body breaches its obligation to contract in good faith and commits dol by silence when it fails to disclose information it knows, even before a formal contract is signed. This principle extends to any seller who possesses material information that would affect the buyer\u2019s decision.<\/p>\n The most significant recent development came on 28 May 2026, when the Third Chamber of the Cour de cassation, sitting in its full section formation, delivered a ruling now published in the Bulletin: Cass. 3e civ., 28 May 2026, no. 24-20.821 (FS-B)<\/a>. The facts of the case illustrate the risk that foreign buyers often face. In 2016, a couple purchased an apartment in Paris for \u20ac710,000. After moving in, they discovered that the occupant of the neighbouring apartment engaged in behaviour that created a significant security problem. They sued the sellers, alleging dol: the sellers had failed to disclose the neighbour\u2019s conduct, which materially affected the property\u2019s value and habitability.<\/p>\n The Paris Court of Appeal found dol and awarded the buyers damages equal to 15% of the purchase price\u2014\u20ac106,500\u2014representing the diminution in value caused by the security problem, without requiring proof that the buyers could have negotiated a lower price. The sellers appealed, arguing that the proper remedy for dol (where the buyer chooses not to seek rescission of the sale) is solely the loss of a chance to have contracted on more favourable terms. In doing so, they invoked a line of case law from the 2010s that had narrowed the recoverable damage in dol cases to a probabilistic loss-of-chance analysis.<\/p>\n The Cour de cassation rejected this argument and reinstated a broader remedy. The court stated unequivocally: \u00ab Il r\u00e9sulte des articles 1116 et 1382 du code civil, dans leur r\u00e9daction ant\u00e9rieure \u00e0 celle issue de l\u2019ordonnance n\u00b0 2016-131 du 10 f\u00e9vrier 2016, que l\u2019acqu\u00e9reur d\u2019un immeuble, victime d\u2019un dol, qui a fait le choix de ne pas demander l\u2019annulation du contrat de vente, peut agir en indemnisation d\u2019un exc\u00e8s de prix. \u00bb Translated: \u00ab It follows from articles 1116 and 1382 of the Code civil, in their wording prior to the reform of 10 February 2016, that the purchaser of a property, who is the victim of a dol and has chosen not to seek rescission of the sale contract, may bring a claim for compensation for an excess price. \u00bb The court then confirmed that the appellate judges had sovereignly assessed the diminution in value as a direct consequence of the dol.<\/p>\n For foreign buyers, this ruling is of considerable practical importance. It means that even if a buyer wants to keep the property (which is often the case: the buyer has relocated, renovated, or become attached to the home), they can still claim the difference between the price they paid and the property\u2019s true value without the concealed defect. The court does not reduce the award to a percentage reflecting the probability that a different price might have been negotiated. The damage is the actual depreciation, assessed by the trial judges.<\/p>\n The legal basis for this claim lies in article 1240 of the Code civil<\/a> (the former article 1382): \u00ab Tout fait quelconque de l\u2019homme, qui cause \u00e0 autrui un dommage, oblige celui par la faute duquel il est arriv\u00e9 \u00e0 le r\u00e9parer. \u00bb This foundational provision of French tort law, in force since the Napoleonic codification, simply means that any human act that causes damage to another obliges the person at fault to repair it. Applied to dol, the fault is the seller\u2019s intentional deception, and the damage is the excess price paid.<\/p>\n Foreign buyers should understand that dol does not exist in a vacuum. It operates alongside several interconnected legal mechanisms, each with its own conditions, remedies, and limitation periods. Navigating these options strategically can make the difference between a successful recovery and a worthless claim.<\/p>\n When a buyer can prove intentional deception, dol offers a broader remedy than the garantie des vices cach\u00e9s<\/em>. Under article 1644<\/a>, a buyer who succeeds in a hidden-defect claim has two options: return the property and recover the full price (action r\u00e9dhibitoire<\/em>), or keep the property and recover a partial refund (action estimatoire<\/em>). However, under the garantie des vices cach\u00e9s, the buyer does not need to prove the seller\u2019s knowledge or fraudulent intent\u2014the guarantee operates even where the seller was unaware of the defect, unless a valid exclusion clause exists. The Cour de cassation recently reiterated this principle in Cass. 3e civ., 26 March 2026, no. 24-14.523<\/a>, where it overturned a Papeete appellate ruling that had dismissed a hidden-defect claim on the ground that the buyer failed to prove the seller knew of the defect. The Cour de cassation reminded that \u00ab le vendeur est tenu des vices cach\u00e9s, quand m\u00eame il ne les aurait pas connus, \u00e0 moins que, dans ce cas, il n\u2019ait stipul\u00e9 qu\u2019il ne sera oblig\u00e9 \u00e0 aucune garantie \u00bb: the seller is liable for hidden defects even where they did not know of them, unless the sale contract contains an express exclusion clause.<\/p>\n Importantly, the limitation period differs between the two actions. Under article 1648 of the Code civil<\/a>, the action based on hidden defects must be brought within two years of the buyer\u2019s discovery of the defect. This relatively short window, combined with the need to commission expert reports, makes it critical for foreign buyers to act promptly upon discovering any problem. The dol-based claim, by contrast, is governed by the ordinary five-year limitation period of article 2224 of the Code civil, starting from the day the buyer discovered or should have discovered the fraud. This longer window can be decisive where defects take years to manifest themselves\u2014a common scenario with structural issues, drainage problems, or latent planning violations.<\/p>\n The notaire\u2019s role is also relevant. In the same Papeete case (no. 24-14.523), the Cour de cassation recalled that under article 1382 of the Code civil (article 1240 in current numbering), the notaire is obliged to \u00ab informer et d\u2019\u00e9clairer les parties, de mani\u00e8re compl\u00e8te et circonstanci\u00e9e, sur la port\u00e9e, les effets et les risques de l\u2019acte auquel il pr\u00eate son concours. \u00bb This duty\u2014to inform and enlighten the parties, completely and in detail, about the scope, effects and risks of the deed\u2014means that if a notaire fails to draw the buyer\u2019s attention to a known risk disclosed in the pre-contract documentation, the notaire may be liable for the loss of a chance to avoid the transaction. The court stated: \u00ab La preuve du conseil donn\u00e9, qui incombe au notaire, peut r\u00e9sulter de toute circonstance ou document \u00e9tablissant que le client a \u00e9t\u00e9 averti clairement des risques inh\u00e9rents \u00e0 l\u2019acte que le notaire a instrument\u00e9. \u00bb The burden of proving that adequate advice was given rests on the notaire.<\/p>\n For the non-resident buyer, this offers an additional layer of protection: even if the seller cannot be pursued for dol (for instance, because concealment was not intentional), the notaire may bear responsibility if key information was buried in dense French legal language without adequate explanation.<\/p>\n Prevention always trumps litigation. A foreign buyer can take several concrete steps before, during, and after the purchase to minimise the risk of fraud and to preserve legal recourse if it occurs.<\/p>\nI.
