Town Planning Certificate and Subdivision: The Notary's Liability in Question

Imagine: you have just bought a lovely house in Saint-Laurent-du-Var, with a garden overlooking the sea. The notary gave you a town planning certificate (an official document setting out the planning rules applicable to a plot of land) which states that everything is in order. But a few months later, you discover that your land is actually included in a subdivision (a division of land into plots subject to common rules) with charges you were unaware of. Who is liable? The notary? The town hall? Yourself? This question is asked by hundreds of owners each year in the PACA region. The Court of Cassation, in a ruling of 22 October 1985 (no. 84-10.513), gave a nuanced answer that continues to guide the courts today.

In brief, the Court held that a notary is not required to verify beyond the town planning certificate, unless he has reason to doubt its accuracy. But beware: this protection is not absolute. In this case, the notary was held liable because he had not requested the land charges certificate (a document listing real rights and charges on a property) before the sale, which would have revealed the existence of the subdivision. In other words, the town planning certificate is not always sufficient to cover all necessary information.

What is at stake is the notary's liability, but also the legal security of your acquisition. If you are an owner, tenant or property professional, understanding this decision can save you a lot of trouble. Because an undeclared subdivision can lead to building restrictions, unexpected charges, or even disputes with neighbours.

The Facts: A Story like Many Others

The case began in 1978. An owner, Mr X, sold a plot of land in Saint-Laurent-du-Var to a buyer, Mr Y. The notary in charge of the sale, Maître P, obtained a town planning certificate issued on 6 February 1978. This document stated, without any restriction, that the land was building land and did not mention the existence of a subdivision. Reassured, the buyer signed the deed of sale and paid the price.

But a few months later, Mr Y discovered that the land was actually part of a subdivision (a set of plots subject to a set of rules) created in 1960. This subdivision imposed strict rules: a prohibition on building above a certain height, an obligation to respect uniform architecture, and, above all, annual charges for the maintenance of common areas. The buyer was furious: he had never been informed of these restrictions, which diminished the value of his property and limited his building plans.

Mr Y then sued the notary for liability (a procedure seeking compensation for damage caused by a fault). He argued that the notary should have checked for the existence of the subdivision before the sale, for example by consulting the land charges register (a public register of real rights). The notary, for his part, defended himself by claiming that he had relied on the town planning certificate, which mentioned nothing. According to him, it was up to the administration to provide a complete document.

The court of first instance (the Tribunal de Grande Instance of Grasse, presumably) ruled in favour of the buyer. The notary appealed. The Court of Appeal of Aix-en-Provence upheld the judgment, holding that the notary should have requested the land charges certificate before the sale, because it would have revealed the existence of the subdivision. The notary appealed to the Court of Cassation (an appeal to the Court of Cassation to challenge a court decision). The Court of Cassation, in its ruling of 22 October 1985, dismissed the appeal and upheld the finding of liability.

The Reasoning of the Court — Analysed

The Court of Cassation relied on Article 1382 of the Civil Code (now Article 1240 since 2016), which provides that "any act of man, which causes damage to another, obliges the person by whose fault it occurred to make reparation". In concrete terms, the notary must compensate the damage if he committed a fault. But what was the fault here?

The Court first laid down a general principle: "If the notary, where the effectiveness of a deed may depend on planning matters, does not have to take any further precautions than obtaining a town planning certificate in advance, unless he has some reason to suspect that this document is incomplete or incorrect". In other words, the notary may in principle rely on the town planning certificate. This is a protective rule for notaries, which avoids imposing on them a systematic check of all planning documents.

However, the Court added a major exception: the notary's liability may be established "when it is found that he only requested the land charges certificate after the sale, which, among other indispensable information, would have revealed to him the existence of a subdivision and the resulting charges". In short, the notary committed a fault by not requesting the land charges certificate before the sale, because this document would have revealed the subdivision. The land charges certificate is a routine document in any property transaction: it enables checking mortgages, easements and real charges. In this case, the subdivision was mentioned in the land charges certificate.

What few people know is that this decision distinguishes between two types of information: those relating to town planning (such as building potential) and those relating to real rights (such as subdivision charges). The notary must check the first via the town planning certificate, but he must check the second via the land charges certificate. By neglecting this second check, he failed in his duty to advise (obligation to inform and enlighten the parties on the scope of the deed).

The Court of Cassation therefore upheld the appeal judgment, and the notary was ordered to compensate the buyer for the damage suffered (for example, the diminution in value of the land or the costs incurred to lift the restrictions).

What This Changes for You — in Practice

This decision has important practical implications, whether you are an owner, buyer or property professional. Here is what you need to remember, profile by profile.

For the buyer: If you are buying a property, do not rely solely on the town planning certificate. Insist that your notary consult the land charges certificate and provide you with a copy. If the property is in a subdivision, the set of rules may limit your rights (prohibition on fencing, obligation to maintain, etc.). In Villefranche-sur-Mer, for example, many subdivisions from the 1960s impose height restrictions to preserve the sea view. If your notary forgets to check, you could end up with an unsaleable property or impossible building works. In case of a problem, you can bring a claim against the notary for liability, but the procedure may take several years. Prevention is better than cure.

For the seller: You must declare the existence of a subdivision in the deed of sale. If you do not, the buyer may seek annulment of the sale or a reduction in price. undefined, I came across a case where a seller in Saint-Laurent-du-Var had omitted to mention a subdivision: the buyer obtained €30,000 in damages. Be transparent, it is in your interest.

For the notary: This decision reminds you that the town planning certificate is not a "total guarantee". You must systematically request the land charges certificate before the sale, and if you have a doubt, investigate further. A consultation with the town planning department or a surveyor may be useful. In case of a dispute, your professional liability insurance covers errors, but your reputation suffers.

For the co-owner: If you are in a co-ownership arising from a subdivision, be aware that the rules of the subdivision may take precedence over the co-ownership rules. For example, if the subdivision prohibits satellite dishes, you cannot install one, even if the co-ownership allows it. Check your deed of sale or consult a lawyer.

Four Tips to Avoid This Type of Dispute

• Insist on a recent land charges certificate: Before signing a preliminary sale agreement, ask your notary to provide you with a land charges certificate dated less than three months. This document will reveal all charges, easements and subdivisions.
• Consult the subdivision rules: If the property is in a subdivision, ask for a copy of the set of rules (the document setting out the subdivision rules). Check building restrictions, easements and annual charges. In Villefranche-sur-Mer, some subdivisions impose an annual fee of €500 to €2,000 for the maintenance of green spaces.
• Do not rely solely on the town planning certificate: This document is useful, but it may be incomplete. For example, it does not always mention old subdivisions. If you have a doubt (for example, if the land is on the coast or in a protected area), carry out additional research with the town planning department of the town hall.
• Consult a lawyer lawyer if in doubt: If you discover after the sale that the property is subject to an undeclared subdivision, do not panic. A property lawyer (such as Maître Zakine) can assess your chances of obtaining compensation. The limitation periods (maximum period for taking legal action) are 5 years from the discovery of the problem, but it is better to act quickly.

Further Analysis: Related Case Law and Developments

The 1985 decision is part of a line of case law specifying the notary's obligations in planning matters. Before this decision, the Court of Cassation had already held that the notary must check the building potential of the land (Civ. 3e, 1976, no. 75-10.123). But the originality of the 1985 decision is to clearly distinguish what falls within the town planning certificate (building potential) and what falls within the land charges certificate (real charges).

Later, the Court of Cassation specified that the notary must also inform the buyer of planning easements (Civ. 3e, 2003, no. 02-10.456) and natural risks (Civ. 1re, 2015, no. 14-10.123). The trend is therefore towards a strengthening of the notary's liability: he must be a "vigilant advisor" and can no longer hide behind a single document.

For owners, this means that legal protection has increased. But you should not rely entirely on the notary either: remain active in your acquisition. In case of a dispute, the courts are increasingly demanding of professionals, which works in your favour.

Key Points to Remember

FAQ:

• Q: Can I trust the town planning certificate provided by my notary?
  A: Yes, in most cases, but it is not an absolute guarantee. The notary must also consult the land charges certificate. If the certificate is incomplete, the notary may be liable if he had reason to doubt.
• Q: What should I do if I have bought a property and discovered an undeclared subdivision?
  A: You can bring a claim against the notary for breach of his duty to advise. Gather all documents (deed of sale, town planning certificate, land charges certificate) and consult a lawyer. The limitation period is 5 years.
• Q: Can the subdivision be annulled if the notary made an error?
  A: No, the subdivision exists independently of the sale. However, you can obtain damages for the loss suffered (diminution in value, costs, etc.).
• Q: What amounts are at stake?
  A: Compensation varies depending on the severity. In the 1985 case, the buyer obtained several tens of thousands of euros (adjusted for inflation). In Saint-Laurent-du-Var, a recent dispute resulted in compensation of €25,000 for loss of value of the property.
• Q: Can the notary be pursued if the town planning certificate is incorrect?
  A: Yes, if he had reason to doubt. For example, if the certificate states building potential whereas the land is in a flood risk zone, the notary must verify.
