Buyer's Estate Agent: When Interposition of a Person Leads to the Annulment of the Sale

Imagine: you put your house in Pithiviers up for sale. You entrust an exclusive mandate to an estate agency. A few weeks later, the agency tells you they have found a buyer: a company. The sale goes through, everything seems normal. But you discover that this company is actually controlled by the estate agent himself. What can you do?

This is exactly the question that arose in a case decided by the French Supreme Court on 2 July 2008. The seller, a company, had given a mandate to sell to an estate agency. The property was bought by another company. But that company was actually run by the estate agent in person. The seller requested the annulment of the sale, arguing that the agent had breached his duty of loyalty.

The Bordeaux Court of Appeal had dismissed the claim, merely stating that the agent (the agency) and the buyer (the company) were two separate legal entities. The French Supreme Court quashed this judgment: it ruled that the judges should have investigated whether the estate agent had acquired the property through the interposition of a person. In other words, they had to check whether, behind the purchasing company, the agent himself was actually hiding.

The Facts: A Story That Happens Every Day

We are in 2004. The Scop Bordeaux International School (which we will call "the school") gives a mandate to an estate agency to sell a building. The agency is run by Mr X. Shortly after, the building is sold to a company called "Y". The price seems fair, the sale is completed.

Except that the school learns that Mr X, the estate agent, is in fact the manager and majority shareholder of company Y. In other words, he himself bought the building he was instructed to sell. The school feels betrayed: the agent should have informed it and, above all, should not have placed himself in a conflict of interest. It sues the agency and company Y in court to have the sale annulled.

The case comes before the Bordeaux Court of Appeal. It dismisses the claim: in the judges' view, the agency and company Y are two separate legal entities. The agent did not buy directly, so nothing illegal. But the school is not satisfied with this answer. It appeals to the Supreme Court. The French Supreme Court, in its judgment of 2 July 2008, rules in favour of the school: the Court of Appeal did not go far enough in its analysis. It should have examined whether there had been an interposition of a person, i.e., whether the agent had used company Y as a screen to buy himself.

What is interesting is that the Supreme Court does not directly condemn the agent, but it obliges the lower courts to carry out a concrete investigation. This is a victory for transparency in property transactions.

The Reasoning of the Court — Analysed

The heart of the problem is this: an agent (here the estate agent) must act in the interest of his principal (the seller). This is a duty of loyalty, provided for in Article 1991 of the Civil Code (the agent is bound to execute the mandate as long as he is charged with it). But there is a more specific rule, arising from case law: an estate agent cannot himself purchase the property he has been instructed to sell. This is an absolute prohibition, because the conflict of interest is too obvious.

Here, the agent did not buy directly. He used a company he controlled. The question is: does this change anything? The Court of Appeal said no, because legal entities are distinct. But the Supreme Court says: "Not so fast!" It reminds that the interposition of a person is a fraud. If the agent hides behind a company to buy, he violates his duty of loyalty. The judges must investigate whether the company was a mere nominee.

The Supreme Court relies on the general principle of contractual loyalty (Article 1104 of the Civil Code, since the 2016 reform, but previously it was Article 1134). It considers that the Court of Appeal should have examined the links between the agent and the purchasing company: who is its director? Who are its shareholders? Are there any capital links? By failing to do so, it deprived its decision of a legal basis.

This judgment is not a reversal but a confirmation and reinforcement of the seller's protection. It shows that judges must be vigilant against legal structures designed to circumvent the rules.

What This Means for You — Practically

If you are a seller, you should know that the estate agent selling your property has an absolute obligation not to acquire it, even indirectly. If you discover after the sale that the buyer is in fact the agent or a company he controls, you can request the annulment of the sale.

Concrete example: you sell a flat in Saint-Jean-de-Braye for €200,000. The agent presents you with a buyer, a SARL (limited liability company). The sale goes through. Six months later, you learn that the manager of the SARL is the agent's son, and that the agent is the real decision-maker. You can bring an action for nullity. The time limit to act is 5 years from the discovery of the fraud (Article 2224 of the Civil Code).

For buyers, be cautious: if you are an estate agent, do not try to buy through an interposed person. The penalty is the annulment of the sale, which means you will have to return the property and recover the price, but with costs and damages. This is a huge risk.

For tenants, this may concern you if you have a right of pre-emption. But in practice, this decision mainly protects sellers.

Four Tips to Avoid This Type of Dispute

• Check the identity of the buyer. In the sale deed, ask to know the shareholders and directors of the purchasing company. If the estate agent or his relatives appear, be wary.
• Require a declaration on oath. Have the agent sign a clause in the mandate where he declares that he is not directly or indirectly interested in the purchase. If false, this is a false statement that can be used in court.
• Do not sign under pressure. If the agent pushes you to sell quickly to a "safe" buyer, take the time to investigate. A buyer that is a company can hide many things.
• Consult a lawyer before the sale. For important properties, a prior legal check can save you from costly litigation. I regularly see clients in Pithiviers or Orléans who could have avoided months of proceedings with a simple check.

This decision is part of a line of cases protecting the seller. The Supreme Court had already ruled, in a judgment of 15 March 2005 (No. 03-16.268), that the estate agent cannot himself buy the property, even if he has informed the seller. The prohibition is absolute.

A more recent judgment, of 10 September 2014 (No. 13-22.706), went further: it annulled the sale of a property acquired by a company in which the agent was a minority shareholder. This shows that the judges are very vigilant. The trend is therefore towards increased protection of the seller against conflicts of interest.

In the future, we can expect courts to require total transparency in property transactions. Estate agents must be exemplary. If you are a seller, do not hesitate to ask questions about the buyer.

What You Absolutely Must Remember

FAQ:

• Can I annul a sale if the agent bought through his company? Yes, if you prove he controlled the company. You must bring legal action within 5 years of discovery.
• What are the risks for the agent? Annulment of the sale, damages, and possible revocation of the professional licence.
• Do I have to prove fraudulent intent? No, it is sufficient to show that the agent had a direct or indirect interest in the purchase. The mere interposition of a person is enough.
• What if the agent is not directly the owner but his spouse? Case law considers this also to be an interposition of a person. Be vigilant.
• How do I know if the buyer is linked to the agent? Request the company's articles of association, the register of beneficial owners, or question the agent in writing. Keep a record.
