A foreign buyer visits a Paris flat through a French estate agent. The viewing is pleasant; the agent walks them through the apartment, the building, the local market. Two days later the same buyer, now genuinely interested, visits the same property through a different agency — a friend’s introduction, more convenient, lower fee. Five weeks after the second visit, the sale completes through the second agency. The first agent finds out, the file lands in court, and on 7 May 2026, the Third Civil Chamber of the Cour de cassation, in n° 24-10.637 (FS-B), awards the first agent €150,000 in damages against the buyer personally — the full commission the agent would have earned if the sale had gone through the original mandate. The buyer is not a party to the agency contract; the legal route is delictual liability under articles 1200 and 1240 of the Code civil.
This is the structural map of a ruling that ends an eighteen-year jurisprudential uncertainty about what counts as a fraudulent circumvention of an estate agent. The headline is that the Cour de cassation has accepted — over the express opposition of its own avocat général — that proven knowledge of the agent’s right to a commission, combined with a behaviour evidencing the will to evade that commission, can constitute the manœuvres frauduleuses required for buyer liability. Foreign buyers who think going around the first agent is harmless arithmetic now face a clearer doctrinal risk on the other side of the closing.
What happened — the Maya Immobilier case
The facts as set out in the Dalloz commentary on the 7 May 2026 ruling are tight. The buyer couple — referenced in the decision as the époux [L] — visited the property on 5 April 2018 with an employee of Concorde Immobilier, the agency holding the original mandate on behalf of the seller, on terms that gave its sister entity Maya Immobilier a right to commission. Two days later, on 7 April 2018, the same buyers visited the same property again — this time through Madame [I] of Zingraf Real Estate, a second agency. During the second visit, after one of the parties (M. [R]) drew attention to the previous viewing through Concorde, the agent of Zingraf Real Estate said she would “s’arrangerait” with M. [E] of Concorde — she described him as “un ami à elle”.
Five weeks after the original visit, the buyers signed a promesse de vente directly with the seller, through Zingraf Real Estate, without the involvement of Concorde Immobilier. The promesse de vente contained a now-decisive clause: the buyer undertook “à prendre en charge la totalité des éventuelles poursuites qui pourraient être formulées par les agences immobilières qu’il aurait contactées pour la présentation de ce bien” — that is, to indemnify against any claims by any agencies they had previously dealt with on the same property. The final acte authentique did not reproduce that clause and did not mention Concorde Immobilier’s earlier involvement.
Maya Immobilier sued the buyers personally for the lost commission. The Cour d’appel granted the agency €150,000 of damages — the full commission it would otherwise have earned on the sale. The buyers cassated. The Cour de cassation, by the 7 May 2026 ruling under the FS-B publication marker, dismissed the cassation.
The Cour de cassation’s holding
The Third Civil Chamber’s reasoning rests on two articles of the Code civil read together. Article 1200 establishes the general principle that contracts have effect only between the parties (relativité), but that they create a juridical fact opposable to third parties; article 1240 is the general delictual liability rule (the post-2016 successor to the old article 1382), under which any human act causing damage to another by fault imposes a duty to repair. The court holds that a third party to a contract who knowingly participates in another party’s breach of that contract incurs delictual liability — and applies the principle to the buyer in an agency context.
In the Cour de cassation’s words, although the buyer is not a party to the agency contract (the mandat between the seller and the estate agent), the buyer is “susceptible d’engager [sa] responsabilité délictuelle à l’égard de l’agent immobilier, lorsque, par son comportement fautif, [il lui a] fait perdre sa commission” — and that loss of commission qualifies as a delictual fault where it results from manœuvres frauduleuses. The behaviour pattern of the buyer, read in the light of the indemnification clause in the promesse, “traduisait une volonté d’agir en fraude aux droits de l’agent immobilier” — translated a will to act in fraud of the estate agent’s rights.
The ruling carries the FS-B publication marker — heard by a section formation (9 to 15 judges) of the Third Civil Chamber rather than the ordinary restricted bench, and published in the Bulletin. Both signal that the Cour de cassation considers the doctrine settled and intended as guidance for the lower courts. The decision was rendered against the express advice of the avocat général, who had urged censure.
The jurisprudential chain — from 2008 to 2026
The 7 May 2026 ruling fits into an eighteen-year arc of decisions that had progressively narrowed and then, in this decision, broadened the buyer’s liability. The story is worth tracing because it explains why the avocat général dissented.
The principle was first established by the Assemblée plénière on 9 May 2008 (n° 07-12.449): even though the buyer is not the debtor of the commission, a buyer whose fault has caused the agent to lose the commission — through whose introduction the buyer had been brought together with the seller — must, on a delictual basis, repair the agent’s prejudice. The 2008 case involved buyers who had taken a fake identity to evict the agent from the transaction. Manœuvres frauduleuses in the strong, dramatic sense.
Three subsequent rulings tightened the screws. Civ. 1re, 6 octobre 2011 (n° 10-21.645) rejected the agent’s action on the ground that “the mere visit of the property could not give rise to any obligation on the buyer’s side” and that the court of appeal had “excluded the existence of a fraudulent concert between the parties.” Civ. 1re, 18 février 2015 (n° 14-12.351) rejected the action even though the court of appeal had recognised that the buyers had manifestly acted in concert with the sellers to circumvent the agent — because the court of appeal had failed to characterise specific manœuvres frauduleuses. And Civ. 1re, 6 décembre 2017 (n° 16-15.249) went further still: the simple fact of acting in one’s own exclusive interest, said the court, does not suffice to characterise a fault or fraud on the rights of a third party — nothing prevented the buyers from contacting the seller directly to offer a lower price, “notably because of the absence of agency commission.”
The 6 December 2017 decision had also noted — and this turns out to be central to the 2026 outcome — that “no fault could be imputed to the sellers, who did not know, when they concluded the act of sale, that they were contracting with buyers who had visited the premises and made a first offer through the estate agent.” Knowledge, in other words, mattered to the 2017 court. The 2026 court has now built on this: when the buyer’s knowledge of the agent’s right to a commission is clearly established by the file, the bar for manœuvres frauduleuses is lower than the dramatic standards of 2008.
Why the 7 May 2026 ruling matters — knowledge + intent
The Cour de cassation in 2026 confirms two findings of the Cour d’appel. First, the buyers knew of the agent’s right to a commission: Madame [L]’s own attestation of 19 January 2019 acknowledged the original visit through Concorde Immobilier two days before the second visit; the second agent’s offhand remark about “s’arranger” with M. [E] confirmed the knowledge; and the clause in the promesse de vente — by which the buyers expressly undertook to indemnify against any claims by previously contacted agencies — confirms that they understood there was a contingent claim hanging over the file.
Second, the buyers’ overall behaviour translated a will to act in fraud of the agent’s rights. The chronology — visit with agent A, visit with agent B two days later, sale through agent B five weeks later — is not, taken in isolation, sufficient. What pushes it over the line is the combination of (a) the buyer’s known awareness of the first agent’s right to remuneration, (b) the deliberate structuring of the closing through the second agency, and (c) the indemnification clause in the promesse de vente that recognised the contingent claim but was carefully excluded from the acte authentique.
The avocat général had argued the opposite — that delictual fault required concrete acts such as the use of a false identity or the misuse of confidential data, and that a visit followed five weeks later by a direct purchase did not in itself satisfy article 1240 of the Code civil. The Cour de cassation rejected that view. The shift from the avocat général’s strict standard to the panel’s holding is small in legal text but meaningful in practice: a documentary trail of knowledge plus a behaviour pattern of evasion can now be enough.
What this means for foreign buyers in 2026
For a foreign buyer the practical implications are concrete. The €150,000 awarded against the buyers in the Maya Immobilier case is not nominal — it equals the full commission the original agent would have earned on the sale. Foreign buyers should approach the agent-circumvention question with a clear understanding of three points.
First, the bon de visite — the document the agent typically asks the buyer to sign at the start of a viewing — is not itself a mandate. It does not, by being signed, oblige the buyer to buy through the agency that presented the property. The Cour de cassation has been consistent on this point since 2011. But, as the 2026 decision makes clear, the bon de visite is evidence that the buyer was introduced to the property by that agent. If the buyer subsequently closes through a different route, the bon de visite supports the agent’s knowledge-establishment case. Foreign buyers should sign bon de visite documents understanding what they are establishing.
Second, the indemnification clauses increasingly written into promesses de vente — clauses where the buyer expressly undertakes to handle any claims by previously contacted agencies — are themselves probative of knowledge. The Cour de cassation in 2026 reads the existence of such a clause as evidence that the buyer understood there was a contingent claim, and uses the deliberate exclusion of that clause from the acte authentique as evidence of a will to obscure the prior contact. A buyer signing a promesse de vente with such a clause should think carefully about whether they have, in fact, visited the property through any other agency — and should disclose that to their notary before signing.
Third, the “saving the commission by going around the agent” arithmetic is no longer the obvious bargain it may have appeared. On a Paris transaction at €500,000 with a typical agent commission of 4% to 5%, the commission is €20,000 to €25,000; on a €1.5 million transaction the same percentage produces €60,000 to €75,000. A buyer who saves the commission by routing the sale around the original agent now faces — under the 7 May 2026 doctrine — a contingent liability for that commission as delictual damages, plus the cost of defending the claim. The economics of circumvention have shifted, and the foreign buyer who thinks they have negotiated a smart double-agency route should expect more scrutiny.
The avocat général’s dissent and what comes next
The avocat général at the Cour de cassation had recommended the panel censure the cour d’appel — that is, find that the appeal court had misapplied article 1240. For the avocat général, the elements established by the cour d’appel — a visit through Concorde Immobilier, a purchase five weeks later through a different agency, no formal notification to the first agency — were not, of themselves, constitutive of either fault or manœuvres frauduleuses. The avocat général’s standard for fraud required acts such as the use of a fake identity for the visit or the misappropriation of confidential data identifying the seller — the strong-sense standard of the 2008 Assemblée plénière decision.
By rejecting the avocat général’s view, the Cour de cassation has acknowledged that the strong-sense standard of 2008 does not exhaust the field. A documentary trail of knowledge, coupled with a behaviour pattern of evasion, can satisfy the manœuvres frauduleuses threshold. This is the doctrinal opening that the title of the Dalloz commentary refers to when it says the 7 May 2026 ruling “opens new horizons.”
The open question the decision raises — and which the Dalloz commentary flags — is whether the same evidentiary route can be applied to clauses in bons de visite rather than just clauses in promesses de vente. The bon de visite, while not itself a mandate, is a document signed by the buyer at the start of the agency relationship; if a clause in the bon de visite were drafted to acknowledge the buyer’s awareness of the agent’s right to commission and the consequences of circumventing the agency, that could supply the knowledge element of the 2026 doctrine even more cleanly than relying on later clauses in the promesse de vente. Estate agents will almost certainly start drafting bon-de-visite clauses to that effect over the coming months.
The honest closing position
For most foreign buyers of French residential property, the agent-commission question never becomes a problem — the buyer visits the property through one agency, contracts through that agency, the commission is paid by the seller out of the sale proceeds, and no one is the worse for it. The 7 May 2026 ruling matters at the margin, in the small number of cases where a buyer with multiple agencies in play structures the closing to evade a commission they had reason to know was owed. In those cases, the doctrinal position has now moved against the buyer.
The practical takeaway is two-sided. For the buyer: be candid with your notary about every agency through which you have visited the property; do not sign indemnification clauses in a promesse de vente without disclosing your prior agency contacts; treat the bon de visite as more than a polite formality. For the seller: the 7 May 2026 ruling does not change the seller’s position — the seller’s obligation to pay the commission under a mandate is unaffected — but it does mean that an attempt to negotiate a lower-commission closing with a circumventing buyer carries new contingent liability on the buyer’s side rather than the seller’s.
The wider French residential-purchase picture within which this ruling sits — the choice of pre-sale contract between compromis and promesse de vente, the step-by-step buying procedure from house-hunting to acte authentique, the acquisition transaction costs that follow at closing, and the all-in cost of holding French property afterwards — all matter alongside the agent-commission question. The agent’s commission is part of the cost the buyer pays through the price, whether the agent collects it from the seller or the buyer ends up paying it again as damages.
Frequently asked questions
Does signing a bon de visite oblige me to buy through that agency?
No. The Cour de cassation has been consistent since at least 2011 that the bon de visite is not a mandate and does not, by being signed, oblige the buyer to buy through the agency that presented the property. But the 7 May 2026 ruling makes clear that the bon de visite is evidence the buyer was introduced to the property by that agent. If the buyer subsequently closes through a different route, the bon de visite supports the original agent’s case that the buyer knew about the agent’s right to commission.
Can I visit a property through one agency and buy through another?
Yes — there is no statutory prohibition. But after the 7 May 2026 ruling, the foreign buyer should understand the risk. If the original agency has a non-exclusive or exclusive mandate from the seller on the property in question, and the buyer’s documented behaviour evidences a deliberate circumvention of that mandate, the buyer can be held delictually liable for the lost commission as damages — even though the buyer is not party to the mandate.
What proves “knowledge” under the 7 May 2026 standard?
The Cour de cassation accepted three converging pieces of evidence in the Maya Immobilier case: the buyer’s own written attestation acknowledging the original visit, the second agent’s offhand remark about “arranging” with the first agent, and the indemnification clause in the promesse de vente expressly recognising the contingent claim. A documented sequence of viewings through multiple agents, combined with a knowing-circumvention behaviour pattern, is now sufficient.
What’s the legal basis under the Code civil?
Articles 1200 and 1240 of the Code civil read together. Article 1200 establishes the principle that contracts have effect only between the parties, but that they create a juridical fact opposable to third parties; article 1240 is the general delictual liability rule (the post-2016 reform successor to the old article 1382), under which any act causing damage to another by fault imposes a duty to repair. The buyer’s tortious complicity in the seller’s breach of the mandate is what triggers the liability.
What damages can the agent recover?
The Cour d’appel awarded €150,000, equal to the full commission the original agent would have earned on the sale. The Cour de cassation did not disturb that quantification. As a general principle of French delictual damages (réparation intégrale), the agent recovers the full extent of the prejudice caused — typically the lost commission, possibly augmented by legal and incidental costs. The buyer’s defence costs are separate and not recoverable from the agent.
What should I do if I have already visited a property through multiple agencies?
Disclose the multiple visits to your notary before signing any pre-sale contract. The notary can then either include a precise indemnification clause assigning the commission risk to the seller (where commercially possible) or, more commonly, arrange a settlement between the agencies before closing. Trying to hide the prior contacts is exactly the behaviour pattern that the 7 May 2026 ruling treats as evidencing a will to defraud.
