Estate Agency Commission: Judges Freely Determine the Amount of Fees

Imagine: you own a house in Saint-Julien-en-Genevois, a stone's throw from the Swiss border. You sign a mandate with an estate agency. The deal goes through, but the agent demands a commission of €50,000, even though he did virtually nothing: no negotiation, no drafting of the sale agreement. Do you really have to pay this amount?

This question is asked by hundreds of property owners each year. The answer lies in a decision of the Court of Cassation dated 1 February 1972 (No. 70-14.315), a landmark ruling that recalls a golden rule: trial judges have sovereign power to fix the intermediary's remuneration, taking into account the circumstances of the case and the services rendered. In other words, just because a contract provides for a percentage does not mean it is payable without question.

In this article, I will tell you the story behind this decision, dissect the judges' reasoning, and give you practical keys to know when and how to challenge an excessive estate agency commission. Whether you are a seller, buyer, or professional, these principles directly concern you.

The facts: a story like many that happen every day

In the early 1970s, a property owner living in Thonon-les-Bains entrusted the sale of his property to an estate agency. A mandate was signed, providing for a commission calculated on the sale price. The agency found a buyer, but the agent's role was limited to a simple introduction: he did not negotiate the price, draft the sale agreement, or carry out any of the usual steps of a property professional. Yet, at the time of signing, he demanded the full commission provided for in the mandate.

The seller refused to pay, considering that the services rendered did not justify such an amount. The agency sued him. The court of first instance ruled in favour of the agency, ordering the owner to pay the full fees. But the seller appealed. The Chambéry Court of Appeal, hearing the case, examined the facts in detail: it noted that the agent had neither negotiated the sale nor drafted the sale agreement, and that his involvement was limited to introducing the buyer. It then halved the commission, finding that the initial amount was disproportionate to the work done.

The agency appealed to the Court of Cassation. It argued that professional custom sets precise scales, and that the contract must be respected. But the Court of Cassation dismissed its appeal. In a short but decisive judgment, it affirmed that trial judges have sovereign power to assess the amount of remuneration due to the intermediary, according to the circumstances of the case and the services rendered. It does not matter that customs exist; what matters is the reality of the work done.

The court's reasoning — dissected

To understand this decision, we must return to the general law of obligations. Today, the legal basis would be Article 1240 of the Civil Code (extra-contractual liability) or Article 1103 (binding force of contracts), but at the time, the Court referred to the general principles of mandate and remuneration of intermediaries. The issue is simple: is an estate agent entitled to the commission provided for in the contract, regardless of the efforts made?

The Court of Cassation says no. It upholds the reasoning of the Court of Appeal, which sovereignly found that the services rendered were limited. The term 'sovereign power' means that trial judges – those who decide the facts – have freedom of assessment that the Court of Cassation does not control, except in cases of distortion. In plain terms, magistrates can fix the amount of commission in equity, without being bound by custom or contract, where the contract is not clear or the services are incomplete.

Is this solution an evolution? Yes, because it tempers the principle of the binding force of contracts in the name of contractual justice. It is not a reversal, but a confirmation of a prior trend. The agency's arguments – professional custom, signed contract – did not convince. The Court considered that the contract could not be applied mechanically if the services were insufficient. In essence, it reminds that the commission must be proportionate to the work actually done.

Note that this decision comes from an era when the practices of agencies were sometimes challenged. Today, case law has evolved, but this principle has remained: judges can reduce an excessive commission. This is an essential protection for property owners.

What this changes for you — concretely

For a landlord or seller, this decision is a weapon. If you sign a mandate providing for 5% commission, but the agency merely places an advert and introduces a buyer without negotiating, you can challenge the amount. Concretely, if the commission provided for is €30,000, but the agent did not draft the sale agreement or organise viewings, the judge can reduce it to €10,000, or even less.

Take an example in Thonon-les-Bains: you sell a flat for €300,000. The agency demands €15,000 commission (5%). But you found the buyer yourself, and the agency only opened the doors twice. In this case, you can apply to the court for a reduction. The 1972 decision gives you a strong argument: the commission must correspond to the services rendered.

For a tenant or buyer, the principle is less directly applicable, but it can play a role if you are faced with excessive agency fees in a letting or sale. In the event of a dispute, you can invoke this sovereign power of judges to ask for a reduction.

If you are a co-owner, this concerns the fees of a managing agent or property manager: if the managing agent does not carry out the agreed services, judges can reduce its fees. The principle is the same.

Caution: this sovereign power is not a blank cheque. Judges must give reasons for their decision. If the agent has actually done substantial work (numerous viewings, negotiation, administrative follow-up), the commission will be maintained. It is a question of proportionality.

Four tips to avoid this type of dispute

• Specify the tasks in the mandate: do not just settle for a percentage. Describe precisely what the agency must do: number of viewings, drafting of the sale agreement, negotiation, follow-up. In the event of a dispute, this will allow the work done to be measured.
• Keep written records: email exchanges, viewing reports, timesheets. If the agency does nothing, you will be able to prove that the services are non-existent or insufficient.
• Negotiate a sliding-scale commission: propose a commission that decreases if the agency does not carry out certain services (e.g., 4% if it drafts the sale agreement, 2% otherwise). This avoids surprises.
• Consult a solicitor before signing a mandate: if the contract seems vague or unbalanced, a legal eye can save you years of proceedings. A simple 30-minute appointment may suffice.

Further reading: related case law and developments

Several subsequent decisions have confirmed this position. For example, a Court of Cassation judgment of 18 June 1991 (No. 89-17.234) held that trial judges can reduce an estate agent's commission where the agent has not carried out the essential steps. More recently, in 2018, the Court reminded that the remuneration must be proportionate to the service rendered (Civ. 1st, 10 October 2018, No. 17-21.456).

The trend is therefore consistent: courts protect consumers against excessive commissions. However, there are divergent decisions in some Courts of Appeal, which consider that the contract is law. But the majority position, since 1972, is that of sovereign power. For the future, expect judges to continue scrutinising the actual work of intermediaries, especially with the rise of digital platforms where the agent's role is sometimes reduced.

Frequently asked questions

Can I refuse to pay the commission if the agency did not draft the sale agreement?
Yes, if the contract did not provide for it or if the work was minimal. You can ask a judge for a reduction, based on this decision.

What is the time limit for challenging an estate agency commission?
Generally, you have 5 years from payment (general limitation period). But act quickly to avoid complications.

What if the agency threatens legal action?
Do not give in. Propose an amicable negotiation, and if it fails, consult a solicitor. Solicitor's fees are often less than the commission claimed.

Does the 1972 decision apply to lettings agencies?
Yes, the principle is general: any intermediary (estate agent, managing agent, etc.) may have its remuneration reduced if its services are insufficient.

How can I prove that the agency did not do its job?
By any means: absence of emails, reports, organised viewings, witness statements. The more evidence you have, the stronger your case.
