Property Developer: The Public Policy of the Hoguet Law Protects You Even Without a Written Mandate

You have signed a preliminary sale contract with a property developer in Boulogne-Billancourt. The salesperson who presented the programme promised you the moon: a price reduction, high-end finishes, rapid delivery. But a few months later, nothing goes as planned. The works are delayed, the finishes are poor, and you discover that the salesperson was neither an estate agent nor a registered agent on the register of estate agents (the famous "RCS" with the professional card). You ask yourself: did this salesperson have the right to do what they did? And above all, can I take action against him or against the developer?

The Court of Cassation ruled on this question on 23 February 2012 in a landmark case (No. 10-18.343). It reiterated a fundamental principle: the provisions of Law No. 70-9 of 2 January 1970, known as the "Hoguet Law", which governs the activity of estate agents, are of public policy. This means they apply to everyone, even if the contract does not mention them, and even if the person involved claims to be a "mere introducer of business" or acts on behalf of a developer. In other words, a salesperson who habitually shows properties, negotiates prices or draws up documents for a developer is subject to the same obligations as an estate agent: they must hold a professional card, have financial guarantee and professional liability insurance. If they do not, you can invoke the nullity of the contract or claim damages.

But what does this actually change for you? How should you react if you are in this situation? This article analyses the decision, explains the judges' reasoning and gives you practical advice to avoid pitfalls.

The Facts: A Story That Happens Every Day

Mrs X., owner of a plot of land in Nîmes, entrusted the marketing of her housing development to the company COPAG, a property development company. In 2006, she signed an initial deed, then twelve marketing addenda. But very quickly, disagreements arose: Mrs X. considered that COPAG had exceeded its role and had not respected the rules applicable to estate agents. In reality, COPAG did not hold the professional card required by the Hoguet Law. It presented itself as a "developer", but in practice it carried on a habitual activity of estate agency (i.e. it brought together sellers and buyers, visited properties, negotiated prices).

Mrs X. then sued COPAG, seeking nullity of the marketing contracts and damages. COPAG, now the Compagnie Immobilière, defended itself by arguing that it was not an estate agent, but a mere developer. According to it, the Hoguet Law would only apply to "pure" estate agents, not to developers marketing their own programmes.

The Nîmes Court of Appeal, in a judgment of 25 February 2010, ruled in favour of Mrs X.: it found that COPAG exercised a habitual and main activity of estate agency, as evidenced by the twelve marketing addenda. For the judges, it did not matter that COPAG was a developer: as soon as it habitually assists in transactions for the purchase, sale or letting of immovable property, it is subject to the Hoguet Law. The company appealed to the Court of Cassation.

The Court of Cassation dismissed the appeal and upheld the Court of Appeal's decision. In a very clear judgment, it stated that "the public policy provisions of Law No. 70-9 of 2 January 1970 and Decree No. 72-678 of 20 July 1972 apply to persons who habitually carry on or assist in the operations provided for in Article 1 of that Law, even on behalf of developers, whether or not those developers are owners of the immovable property in question." In short, a developer who acts as an estate agent is treated as an estate agent.

The Reasoning of the Court — Analysed

To understand this decision, you first need to know the Hoguet Law. This law, passed in 1970, aims to protect consumers in real estate transactions. It requires any person who carries on or assists in operations of purchase, sale, letting, sub-letting, exchange, etc., to provide:

• a professional card issued by the chamber of commerce;
• a financial guarantee (to cover funds held on behalf of clients);
• professional liability insurance;
• and to comply with strict ethical rules.

Article 1 of the law lists the operations covered: sale, purchase, letting, sub-letting, exchange, etc. Article 3 provides that persons who carry on these operations must hold a professional card.

In this case, the Court of Cassation relied on the public policy nature of the law. Public policy is the set of mandatory rules that protect the general interest and cannot be derogated from by contract. Thus, even if COPAG argued that it was only a developer and that its contract with Mrs X. did not mention the Hoguet Law, this law still applied because it is of public policy.

The judges also interpreted the expression "assist in" broadly. It is not necessary to be a registered estate agent to be subject to the law: it is enough to habitually participate in real estate operations. Here, COPAG had signed twelve marketing addenda, demonstrating a habitual activity.

Finally, the Court rejected COPAG's argument that it was not the owner of the properties. The Hoguet Law applies to both owners and non-owners: what matters is the activity of estate agency, not ownership of the properties.

What few people know is that this decision is part of a consistent line of case law. Already in 2008, the Court of Cassation had held that a property development company that marketed co-ownership units was subject to the Hoguet Law (Civ. 1st, 30 April 2008, No. 07-13.416). The 2012 judgment confirms and reinforces this position.

What This Changes for You — Concrete Implications

This decision has very practical implications for all real estate players.

For seller-owners (like Mrs X.): if you entrust the sale of your property to a developer who actually acts as an estate agent without a professional card, you can seek nullity of the mandate or marketing contract. This means you are not obliged to pay the agreed fees, and you can even claim damages if you have suffered loss (for example, if the developer sold the property at a price below market value). Example: an owner in Évry entrusts the sale of his flat to a developer who markets it without a card. The sale is concluded at €200,000, but the developer takes €20,000 in fees. The owner can sue for nullity and recover the €20,000.

For buyers: if you buy a property through a developer who does not have a professional card, you can invoke nullity of the sale or claim damages if you were misled. For example, if the developer promised you amenities that were not provided, you can take action against him, even if he is not an estate agent. However, nullity is not automatic; you must show that the absence of a card caused you loss.

For developers: this decision obliges them to comply with the Hoguet Law if they carry on an estate agency activity. Many developers think they are exempt because they sell their own properties. This is not the case if they act on behalf of others (e.g. if they market units for another owner). undefined, I have come across cases where developers were sued for significant sums by dissatisfied owners, and they could not rely on their status to escape their obligations.

If you are in this situation, you must: check whether the person or company that presented the property holds a professional card. You can consult the register of estate agents on the chamber of commerce website. If not, you can consider legal action. The limitation period is 5 years from the discovery of the lack of a card.

Four Tips to Avoid This Type of Dispute

• Check the professional card of the intermediary before any commitment. Ask to see the card and note the number. Verify its validity on the chamber of commerce website. If you are told it is not necessary because it is a developer, be wary.
• Require a written and detailed mandate. The mandate must mention the fees, duration, conditions of sale. If the developer refuses to give you a written mandate, that is a red flag.
• Keep all documents exchanged. Emails, advertisements, visit reports can prove the habitual activity of estate agency. In case of dispute, this evidence is essential.
• Consult a lawyer lawyer at the first signs of difficulty. A professional can assess whether the intermediary is subject to the Hoguet Law and advise you on possible remedies. A quick consultation can avoid months of proceedings.

Further Analysis: Related Case Law and Developments

The decision of 23 February 2012 is not isolated. It is part of a line of judgments that extend the scope of the Hoguet Law. For example, the Court of Cassation has held that management companies that collect rents on behalf of owners are subject to the Hoguet Law (Civ. 1st, 14 January 2010, No. 08-20.529). Similarly, property dealers who buy to resell are concerned if they engage in estate agency activity.

The trend is therefore towards increased consumer protection. The courts are vigilant not to allow companies to circumvent the law by presenting themselves as developers or introducers of business. In 2015, another decision clarified that even a non-profit association could be subject to the Hoguet Law if it habitually carried out real estate transactions (Civ. 1st, 9 September 2015, No. 14-20.138).

For the future, we can expect case law to continue to extend the scope of the law, especially as practices evolve (online platforms, commercial agents, etc.). What this means for you: never assume that a person is not subject to the Hoguet Law; always check.

Frequently Asked Questions

Can I cancel a sale if the agent did not have a professional card?
Yes, you can seek nullity of the sale if you prove that the lack of a card caused you loss. But nullity is not automatic; the judge assesses on a case-by-case basis. It is more common to obtain damages.

What if I have already paid fees to a developer without a card?
You can claim reimbursement of the fees, as the contract is void if the estate agency activity was habitual. Seize the judicial court within 5 years.

What are the time limits for taking action?
The limitation period is 5 years from the day you discovered the lack of a card. Do not delay.

Is a developer who sells his own programmes subject to the Hoguet Law?
No, if he sells only his own properties and without intermediation. But as soon as he markets properties on behalf of a third party (even occasionally), the law applies.

How can I check if a company has a professional card?
Go to the chamber of commerce website of its registered office. You can also ask to see the card and verify the number.
