Every year, hundreds of foreign buyers purchase French property based on promises of steady rental income. A well-located apartment in Paris, a villa on the Riviera, or a ski chalet in the Alps — all wrapped in a projection showing yields of 4, 5, even 6 percent. What happens when those numbers turn out to be fiction? French law provides remedies, but they hinge on technical distinctions that most foreign investors discover too late. The past three years have produced a concentrated wave of rulings from the Cour de cassation (the French Supreme Court for civil and commercial matters) clarifying when a buyer can have a sale annulled — or recover damages — because the rental profitability promised was simply not there. This article maps those remedies: dol (fraud), erreur (mistake), the seller’s pre-contractual duty to inform, the critical question of when the clock starts running, and the financial consequences an annulment triggers.
I. The Legal Framework: When a Promise of Profitability Becomes Actionable
A. The Three Pillars: Dol, Erreur, and the Duty to Disclose
French contract law, recast by the 2016 reform that took effect on 1 October 2016, organises the protection of consent around three converging doctrines. Article 1130 of the Code civil provides that mistake (erreur), fraud (dol), and duress (violence) vitiate consent when, without them, a party would not have contracted or would have contracted on materially different terms — to be assessed “in light of the persons and circumstances in which consent was given” (C. civ., art. 1130).
Erreur, defined by article 1132 of the Code civil, is a ground for nullity when it concerns “the essential qualities of the performance owed or those of the other contracting party” — unless the mistake is inexcusable (C. civ., art. 1132). The profitability of an investment property is precisely such an essential quality: if a buyer purchases a property solely to generate rental income, and the income it can realistically produce is a fraction of what was represented, the buyer’s consent may have been given in error.
Dol goes further. Article 1137 of the Code civil defines it as “obtaining the other party’s consent by manoeuvres or lies,” and adds that “intentional concealment by one contracting party of information whose decisive character for the other party he knows” also constitutes dol (C. civ., art. 1137). The 2018 reform codified réticence dolosive — fraudulent silence — making it clear that a seller who deliberately withholds information about the true earning capacity of a property can be held liable even without an outright lie.
These two doctrines are reinforced by the general pre-contractual duty of information in article 1112-1 of the Code civil: a party who knows information of decisive importance for the other’s consent must disclose it when the other legitimately ignores it or relies on the counterparty. The text expressly states that this duty “does not extend to the estimation of the value of the performance” — meaning a seller need not volunteer that the price is above market — but it does cover facts about the property itself, including its income history, tenant defaults, and known structural or regulatory obstacles to achieving the projected yield (C. civ., art. 1112-1). A breach of this duty can, “in addition to the liability of the party who was bound by it, result in annulment of the contract under the conditions set out in articles 1130 et seq.”
For a foreign buyer, these provisions matter enormously. In a typical acquisition, the parties sign a compromis de vente (preliminary sale agreement), at which point the sale becomes binding between them under article 1583 of the Code civil: “It is perfect between the parties, and ownership is acquired by operation of law in favour of the buyer as against the seller, as soon as the thing and the price have been agreed upon, even though the thing has not yet been delivered nor the price paid” (C. civ., art. 1583). A promise of profitability made before or at this moment, if false, can taint the entire transaction.
B. When the Courts Grant Annulment: The Garrigae / Les Jardins de Saint-Benoît Litigation
The most sustained judicial treatment of misleading profitability promises in recent years comes from a series of cases involving a tourism residence development in the south of France. The developer, Les Jardins de Saint-Benoît (later JSB), sold furnished houses in a holiday residence (résidence de tourisme) to investors — many of them based in Ireland, the United Kingdom, and China — with a promised commercial lease to Garrigae Hotels And Resorts. A marketing brochure, produced by the firm HPA Holding (formerly Groupe Garrigae), promised investors “guaranteed rental income” of 2.5 to 4.5 percent per year, with “full ownership without the hassle and uncertainty that goes with renting and maintaining a property.”
The returns never materialised. Within a few years, rents were reduced by avenants, the original operator was substituted or placed in insolvency, and several investors sued. The third chamber of the Cour de cassation issued no fewer than five rulings arising from these facts between March and July 2025.
In Cass. 3e civ., 5 June 2025, no. 23-14.493, the court confirmed the core principle: when a buyer proves that a misleading commercial brochure induced his consent, the sale may be annulled for dol. The lower court had annulled the sale of a property purchased for €282,256 on 20 November 2007, finding that the brochure’s promise of guaranteed income — without corresponding disclosure of the known risk that the operator was fragile — constituted a fraudulent manoeuvre. The Cour de cassation did not disturb this finding; it reversed only on the technical question of which party must refund the bank (discussed in Part II).
In Cass. 3e civ., 20 March 2025, no. 23-14.446, the same analysis was applied to a buyer who had paid €326,508 in 2008. The court confirmed the lower court’s annulment for dol, and added the rule that restitution obligations flowing from an annulled sale are owed between the parties to the annulled contract: the buyer must return the property, the seller must return the price, and the non-contracting marketing company cannot be ordered to make restitutions on the same basis — though it may be liable in tort.
The principle that a misleading projection of rental yield can constitute dol was forcefully reiterated in Cass. 3e civ., 16 March 2023, no. 21-25.984, where the court held that the seller, “bound to inform even a sophisticated investor of the risks inherent in purchasing property within a tax-incentive programme, must demonstrate that it fulfilled that obligation, without remaining silent on the risks associated with it.” The brochure in that case promised guaranteed profitability, but the tenant went into insolvency within fourteen months of the sale.
A different fact pattern, but one reinforcing the seller’s duties, arose in Cass. 3e civ., 5 February 2026, no. 23-21.993. A buyer purchased a twelve-unit rental building for €210,000, based on an agency listing that touted “twelve furnished rental units” and an annual rental report. After the sale, the local health and housing authority informed him that six units on the second floor failed mandatory habitability standards — insufficient floor area and ceiling height — making them unlawful to rent. The Cour de cassation upheld the resolution of the sale for breach of the obligation of délivrance conforme (delivery of a conforming item), reasoning that “the rental destination of the building was one of the characteristics of the property sold” and the sellers, having received notice of an upcoming inspection before the sale, bore a duty to inform the buyer — which they breached.
II. Practical Consequences and Pitfalls for Foreign Investors
A. The Prescription Clock: When Does the Five-Year Period Start?
This is the issue on which most foreign buyers fail. The prescription period for an action in dol or contractual liability is five years under article 2224 of the Code civil. The question is: five years from when?
In a crucial pair of decisions, the Cour de cassation has established a rule specifically for tax-incentive rental investments. The starting point is not the date of sale, but the date on which the buyer becomes aware — or should have become aware — of the impossibility of achieving the promised profitability. In Cass. 3e civ., 5 June 2025, no. 23-20.449, the court held: “In the context of a rental property investment benefiting from a tax-incentive scheme, the manifestation of damage to the buyer can only arise from facts likely to reveal to him the impossibility of obtaining the profitability projected at the time of the contract’s conclusion” (citing Cass. 3e civ., 26 October 2022, no. 21-19.898, published).
The lower court had dismissed the action as time-barred, reasoning that the buyers should have known the value was overstated when they bought in 2009. The Cour de cassation reversed: the buyers argued that the profitability had to be assessed globally — combining purchase price, rental income, and tax benefit — and they only learned of the overvaluation through a professional appraisal dated 16 April 2015. The same principle was applied in Cass. 3e civ., 26 June 2025, no. 23-21.812, where the court again censured a lower court for starting the prescription clock on the date of the authentic deed, when the investment was a tax-incentive scheme and the buyer only became aware of the overvaluation through an estate agent’s valuation in August 2016.
The practical lesson for a foreign buyer is that the five-year clock does not necessarily start ticking when the first disappointing rental cheque arrives. It starts when the overall impossibility of the projected yield becomes manifest — often a much later date, and one that the buyer should document carefully with appraisals, correspondence with agents, and accounting records.
B. What Annulment Actually Costs — and Who Pays
A successful annulment (nullité) of the sale under article 1178 of the Code civil retroactively extinguishes the contract: it is treated as if it never existed, and the parties are restored to their pre-contractual positions (C. civ., art. 1178). The practical arithmetic is as follows.
The buyer must return the property — and bears no further obligation towards the seller. The seller must return the purchase price, including the portion financed by the buyer’s own funds (the apport personnel). If the seller is insolvent, that is the buyer’s risk.
If the purchase was financed by a bank loan, the annulment of the sale automatically triggers the annulment of the loan, because French law treats the two contracts as interdependent (interdépendance). The critical rule, affirmed consistently by the third chamber throughout 2025, is that the obligation to repay the loan capital to the bank falls on the borrower — not on the seller — even though the seller received the loan proceeds as part of the purchase price. In Cass. 3e civ., 5 June 2025, no. 23-14.493, the court stated this unambiguously: “The obligation to repay the capital to the lender, following the extinguishment of an allocated credit agreement, itself subsequent to the nullity or resolution of the principal contract, falls on the borrower — party to the loan agreement — and not on the seller, even if the funds were paid directly to the seller at the borrower’s request.” The same holding was repeated in Cass. 3e civ., 20 March 2025, no. 23-14.446 and Cass. 3e civ., 10 July 2025, no. 23-14.495.
This means the buyer who succeeds in having the sale annulled must still repay the bank the principal borrowed — a sobering consequence that renders the remedy less valuable where the property has depreciated or where the buyer cannot recover the price from the seller. However, the buyer may also claim damages against the seller, the marketer, and, where applicable, the notary or estate agent, for the losses suffered, including loan interest, notarial fees, and the cost of the annulment procedure itself.
The seller’s obligation of information also extends beyond the moment of the sale. In Cass. 3e civ., 21 December 2023, no. 22-21.518, the Cour de cassation applied article 1602 of the Code civil, which provides that “the seller is bound to explain clearly what he binds himself to. Any obscure or ambiguous clause shall be interpreted against the seller” (C. civ., art. 1602). The court censured a lower court for failing to consider whether the mention of an attic (grenier) in the deed necessarily implied that it was usable — the ambiguity having to be resolved against the seller who drafted the description.
For a foreign buyer, these rulings mean three things in practice. First, demand the seller’s rental history — not a projection, but actual tenant payment records, tax declarations, and repair invoices for at least the past three years. A refusal to provide these should be treated as a red flag. Second, obtain an independent valuation of the property’s income capacity from a French estate agent or property manager who is not connected to the seller — this creates a paper trail that will later anchor the starting point of prescription. Third, ensure the compromis de vente and the final deed reference the specific income representations that induced the purchase: if the agent or developer circulated a brochure promising a yield, that brochure should be attached to the deed with a clause confirming the buyer’s reliance on it.
Conclusion
The French courts of the past three years have drawn a clear line: when a seller or marketer promises a rental yield that the property cannot deliver, the buyer has remedies — but those remedies require an understanding of the distinction between erreur and dol, the vigilance to document the date when the impossibility of the yield became apparent, and a sober assessment of what annulment actually means financially. A successful claim unwinds the sale, but leaves the buyer owing the bank the loan principal. The better approach, wherever possible, is to structure the acquisition with verifiable income data and contractual protections — before the compromis is signed — rather than to litigate after the yield fails to arrive. An independent valuation, a review of the seller’s rental history, and the attachment of all income representations to the deed are low-cost measures that can prevent an expensive and procedurally complex claim down the road.
