This article is general information, not legal advice. Agency law is a litigated field where outcomes turn on the wording of individual mandates and the facts of each sale, and the rules described here carry exceptions that only a qualified professional can apply to your situation. Before signing or refusing to pay anything, take advice.

Somewhere in your compromis de vente (preliminary sale contract) sits a line stating who pays the agent and how much, and our experience is that foreign buyers read it once, wince politely at the number, and move on to worrying about the survey they are not getting. That is a pity, because France regulates estate agents more tightly than almost any activity a foreigner will meet in a property purchase, through a statute old enough to have a nickname: the loi Hoguet of 2 January 1970. The regime it created is strict, faintly obsessive about paperwork, and built almost entirely for your protection, which makes it doubly unfortunate that the people it protects rarely know what it says.
This guide walks through the rules that decide when a commission is actually owed, who owes it, and when the answer is nobody at all, using the case law French courts have spent five decades building around agents who tried to get paid anyway. If you would rather start with how the purchase itself unfolds, our step-by-step buying guide is the wider map; this is the close-up on the person in the middle of it.
The one-minute version
An agent earns a commission only if four conditions line up: a professional licence (the carte professionnelle), a written mandate signed before any negotiation and carrying a number from the agency’s mandate register, real work that actually produced the deal, and a sale that genuinely completes. Knock out any one of the four and, with narrow exceptions, the commission is not owed – not at the compromis, not after a buyer retracts, not when the mortgage condition fails, and not even when the sale is signed but later annulled. The money changes hands only after the notarised deed, and demanding it earlier is a criminal offence rather than a billing style. The two ways owners get caught anyway: selling behind an exclusive agent’s back to a buyer that agent introduced, and behaving badly enough toward the agent that a court awards the lost commission as damages.
A statute with teeth, and paperwork with consequences
The loi Hoguet (law no. 70-9 of 2 January 1970) and its implementing decree of 20 July 1972 hang the agent’s entire right to payment on formalities that courts apply with a severity English readers may find bracing. The agent must hold a written, signed and current mandate before carrying out the first acts of negotiation, and the Cour de cassation has repeated for decades that an agent who cannot produce a regular mandate simply has no claim to remuneration (Civ. 1re, 20 Jan. 1993, no. 91-13.729; Civ. 1re, 25 Jan. 2005, no. 02-10.764; Civ. 3e, 19 Oct. 2010, no. 09-16.786).
« L’agent immobilier ne peut réclamer une commission ou rémunération à l’occasion d’une opération […] que si, préalablement à toute négociation ou engagement, il détient un mandat écrit, délivré à cet effet par l’une des parties et précisant la condition de détermination de la rémunération ou commission, ainsi que la partie qui en aura la charge. »
“An estate agent may claim a commission or remuneration in connection with an operation only if, before any negotiation or engagement, he holds a written mandate, issued for that purpose by one of the parties, specifying how the remuneration is determined and which party will bear it.” (Civ. 1re, 6 Jan. 2011, no. 09-71.243)
The formalism runs deeper than the signature. Every mandate must be entered chronologically in the agency’s registre des mandats (mandate register), and the registration number must appear on the copy left with you: miss that mention and the contract is struck by absolute nullity, taking the agent’s commission down with it (Civ. 3e, 28 Oct. 1980, no. 79-12.072; Civ. 3e, 16 Nov. 2004, no. 02-10.301). The stakes can reach past the agent’s fee to the deal itself, because a sale offer made in your name under an irregular mandate does not bind you, and the resulting sale cannot be regarded as validly concluded (Civ. 3e, 8 Apr. 2009, no. 07-21.610). French judges have softened one corner of this edifice in recent years, holding that formal defects protecting only the client’s private interests now produce a relative rather than absolute nullity between the parties (Cass., ch. mixte, 24 Feb. 2017, no. 15-20.411), but the practical advice is unchanged: the paperwork is not decoration, and its absence is your defence.
The mandate you sign, and the five things it must say
Whatever the agency’s branding calls it, the document is a mandat, and articles 6 and 7 of the law dictate its contents. It must state a duration limited in time with a definite end date, because open-ended engagements are void, and the courts have annulled clauses renewing a mandate indefinitely by tacit rollover (Civ. 1re, 22 Apr. 1986, nos. 84-17.187 and 84-17.356) while accepting precisely bounded renewals. It must state the agent’s remuneration and, crucially, name the person who will pay it, a mention whose absence leaves the mandate valid but strips the agent of any right to the fee (Civ. 1re, 13 Mar. 2007, no. 05-12.270). It must set the conditions under which the agent may handle money, describe the actual extent of the agent’s powers, and carry the register number described above.
That fourth item deserves a foreigner’s particular attention, because French courts read agents’ powers narrowly: a document grandly titled “mandat de vendre” that does not expressly authorise the agent to bind the owner is treated as a mere search mandate (Civ. 1re, 8 July 1986, no. 84-15.731), and even an “exclusive sale mandate” does not let the agent sign a binding promise with a buyer unless a specific clause says so (Civ. 1re, 31 Jan. 2008, no. 05-15.774). The agent, in other words, brings you a buyer; unless you have written otherwise, nobody signs your sale but you.
Simple, exclusive, and the clause printed in very large letters
A mandat simple lets you appoint several agencies and sell by yourself, with the commission going only to the agent whose work actually produced the sale, even where another agent introduced the same buyer first (Civ. 1re, 9 July 2002, no. 00-13.410). A mandat exclusif reserves the operation to one agent, and its bite comes from article 78 of the 1972 decree: a clause entitling the agent to commission even where the sale happens without him is enforceable only if it is expressly stipulated and printed in caractères très apparents – very conspicuous type – which is why that paragraph of your mandate looks like shouting. The same article supplies the escape hatch that agencies mention less often: once three months have run from signature, either party may end an exclusive mandate at any time on fifteen days’ notice by registered letter.
The courts police the boundaries of these clauses without much sentimentality. A clause making the parties jointly liable for the agent’s fee as an “indemnity” if they amicably cancelled their own agreement was annulled outright, since it amounted to paying a commission for an operation that never happened (Civ. 1re, 28 Mar. 2000, no. 97-12.737), and consumer-law rules against unbalanced terms apply to mandates like any other standard-form contract signed by a non-professional.
No completed sale, no commission – and the courts mean it
The load-bearing rule of the whole system sits in article 6 of the law: nothing representing commission or fees may be demanded or accepted before the operation has been effectively concluded and recorded in a single written instrument, which for a property sale means the commission becomes payable only once the notarised deed is signed. The brokerage is complete when the sale is perfect between seller and buyer (Civ. 1re, 24 Sept. 2002, no. 00-21.964; Civ. 1re, 16 Nov. 2016, no. 15-22.010), and perfection in this sense arrives only after every suspensive condition is lifted and every withdrawal right has expired.
Each of the ways a French purchase can politely die therefore kills the commission with it. A buyer who exercises the ten-day statutory withdrawal right after the compromis owes the agent nothing, and neither does the seller. A financing condition that fails takes the fee down too, and the Cour de cassation has pushed this to lengths that startle even French practitioners, refusing the agent any remuneration where the condition failed through the buyer’s own fault (Com. 15 Dec. 1987, no. 84-14.443; Civ. 3e, 11 Mar. 2009, no. 04-15.943), and confirming recently that a suspensive condition lapsing at its deadline makes the whole operation fall away along with any right to payment or indemnity for the agent’s wasted efforts (Civ. 3e, 20 June 2024, no. 23-12.106). Even a sale that signs and later collapses follows the pattern: where the transaction is annulled, sums the agent received become undue and must be returned (Civ. 1re, 6 Nov. 2002, no. 99-13.122). Our guide to the compromis and its conditions explains how those exits work from the buyer’s side; the point here is that every one of them is commission-free.
| The situation | Is the commission owed? |
|---|---|
| The sale completes at the notaire | Yes – by whoever the mandate names, payable only after the deed |
| The buyer withdraws in the ten-day cooling-off window | No – by nobody, seller included |
| A suspensive condition fails honestly (mortgage refused) | No – and the courts refuse the agent any indemnity for the wasted work |
| The buyer sabotages a condition or hides resources | No commission – but the buyer risks paying the equivalent as damages |
| The sale completes, then is annulled | No – fees already received become undue and must be returned |
| The seller deals directly with a buyer the exclusive agent introduced | Yes – the seller owes it |
| A public body preempts the sale | Yes – the preemptor assumes the buyer-side fee stated in the declaration |
| No written mandate, or no register number on the client’s copy | No – the agent has no claim at all |
The two ways people end up paying anyway
The first is the exclusive-mandate trap, and it is the one that catches sellers. Where a properly drafted exclusivity or guaranteed-commission clause is in force and the agent has shown the property to a buyer, a seller who then deals directly with that buyer owes the commission, the operation being deemed concluded through the agent’s intermediation (Civ. 1re, 8 July 1994, no. 92-14.346). Waiting out the mandate barely helps if the introduction happened during it; the fifteen-day denunciation route after three months is the legal exit, and quiet direct deals are the expensive one.
The second catches buyers who play games. The document agents ask visitors to sign, the bon de visite, is not a mandate and creates no debt by itself (Civ. 1re, 6 Oct. 1993, no. 91-18.231), but a buyer whose faulty behaviour cheats the agent out of a commission answers for it in damages on ordinary tort principles: the assembled chambers of the Cour de cassation settled the point for a buyer who circumvented the agent that had introduced him to the seller (Cass., ass. plén., 9 May 2008, no. 07-12.449), and the court has likewise made a buyer pay who torpedoed his own mortgage condition by concealing his resources (Civ. 1re, 13 Dec. 2005, no. 03-16.803). The polite summary: the law will not hand the agent a fee for a sale that never happened, but it will make the person who sabotaged the sale compensate him, which from your wallet’s perspective is a distinction without much difference.
Who pays, and what it does to the price
French law does not decide whether buyer or seller pays the agent; the mandate does, and the sale deed must reproduce what the mandate says (Civ. 1re, 13 Mar. 2007, no. 05-12.270). The choice matters beyond psychology, because a commission the mandate places on the buyer (honoraires charge acquéreur) is paid by its true debtor and sits outside the seller’s price, while a seller-side commission is simply part of what you pay for the house, a distinction with real consequences for the taxed base of transfer duties. Display rules force the arithmetic into the open: agency advertising must show the price with and without fees, state who bears them, and give the buyer-side fee as a percentage, all taxes included, under the fee-display rules in force since 2017 and tightened in 2022.
Two situations take the decision out of everyone’s hands. Where a public preemption right intervenes and the sale completes with the preempting authority instead of you, the preemptor who takes the buyer’s place assumes the buyer-side commission, provided the fee and its debtor were stated in the parties’ engagement and in the declaration of intent to sell (Civ. 3e, 12 May 2021, no. 19-25.226). And for residential lettings the law simply overrides the mandate: negotiation fees fall exclusively on the landlord, with only the capped visit, file and inventory fees shared with the tenant.
When a fee is not just wrong but criminal
The Hoguet regime carries a penal wing that explains why serious agencies are careful people. Collecting or even accepting commission money before the parties’ engagement is recorded in writing is punished by up to two years’ imprisonment and a €30,000 fine, and the Cour de cassation has applied it to an agent who merely agreed to a cheque drawn to his order too early (Crim., 6 Mar. 1984, no. 81-94.206). Practising without the carte professionnelle risks six months and €7,500, and since the ELAN law of 2018 the same penalties reach anyone who simply uses the title of agent immobilier without holding the card. If an intermediary in your purchase asks for a “deposit on fees”, a “reservation charge” or any payment before completion, you are not negotiating a billing practice; you are watching an offence being attempted, and the correct response is a polite refusal and a better agent.
What this means at your table
Before signing a mandate as a seller, read three lines with actual attention: the end date, the remuneration clause naming amount and debtor, and anything printed in conspicuous capitals, which is where exclusivity lives. Diarise the three-month mark, because from that day a registered letter and fifteen days end an exclusive arrangement that is not working. As a buyer, remember that the bon de visite you sign at the first viewing is a courtesy record rather than a debt, that no one may ask you for a centime of commission before the notarised deed, and that if your financing condition fails honestly, the agent’s fee disappears with the purchase. Honesty is the operative word: the case law on buyers who fake their way out of conditions or around agents is unforgiving, and rightly so.
The agent’s own duties toward you – verification, advice, and the liability that follows when they fail – are a story of their own, and one a recent Cour de cassation ruling on buyers who go around the agent has already begun telling on this site. If commissions, mandates or a fee demand you doubt are troubling a purchase you are planning or living through, tell us about it: reader questions have a way of becoming the next guide, and the strangest mandate clauses we have seen all arrived by email.
FAQ: agent commissions in four questions
Can the agent ask for part of the commission at the compromis?
No. Nothing representing commission or fees may be demanded or accepted before the sale is effectively concluded and recorded, which in practice means the notarised deed; taking money earlier is a criminal offence under the loi Hoguet, not an industry custom.
My mortgage was refused and the purchase fell through. Do I owe the agent anything?
If the financing condition failed despite a genuine application matching the contract’s terms, no commission is owed by anyone, and the courts have refused agents any indemnity for their wasted work. A buyer who causes the failure – by never applying, or by concealing resources – can instead be ordered to compensate the agent in damages.
I signed an exclusive mandate and found a buyer myself. Must I still pay?
Usually yes while the exclusivity runs, if the clause was express and conspicuously printed, and always where the buyer was one the agent had already introduced. After three months you may end the mandate with fifteen days’ notice by registered letter, which is the lawful route out; selling quietly behind the agent’s back is the litigated one.
Who decides whether buyer or seller pays the commission?
The mandate does, and the sale deed must repeat it. Agency advertising must display the price with and without fees and say who pays; where the fee is buyer-side it sits outside the seller’s price, which slightly reduces the base on which transfer duties are calculated.
