Imagine for a moment: you are the owner in Le Cannet of a wooded plot that you have always used for your pleasure or to obtain some fruits. One day, the neighbouring Droit de préemption urbain : que faire si le vendeur refuse mon prix ?">commune claims ownership of this land, arguing that its residents have, for decades, collected wood or grazed their animals there. How can you prove that this property belongs to you? And can the commune also rely on these acts to establish its possession? This is precisely the question that the Court of Cassation decided in a judgment of 1 June 2005.
This decision, rendered concerning plots located in the commune of Cristinacce, Corsica, directly concerns all residents near communal properties, whether in Le Cannet, Mandelieu or elsewhere. It reminds us that possession of a communal property may result not only from acts performed by the commune itself, but also by its residents. In other words, the acts of enjoyment of individuals can serve to establish the collective possession of the commune.
But what does this change for you, owner of a house in Mandelieu or farmer in the Alpes-Maritimes? This article explains the facts, the judges' reasoning and the practical consequences of this judgment. You will find advice to avoid disputes and understand how to protect your rights.
The Facts: A Story Like Many Others Every Day
The case pits the commune of Cristinacce against another commune, unnamed in the judgment, as well as against residents. For decades, several plots of land, planted with chestnut trees, have been used by the residents of both communes. Some collect chestnuts, others cut wood. But one day, the commune of Cristinacce decides to assert its exclusive right of ownership over these plots.
The commune of Cristinacce then sues the other users before the tribunal de grande instance (TGI, court of general jurisdiction for important civil disputes) to have its exclusive ownership recognised. It argues that it alone possesses these communal properties, and that the acts of the residents of both communes cannot establish concurrent possession. In defence, the other commune and the residents reply that they also enjoy these plots for more than thirty years, which, according to them, characterises concurrent possession.
The TGI rules in favour of the commune of Cristinacce. But the cour d'appel (CA, second instance court that rehears the case) reverses this judgment: it considers that the acts of enjoyment performed by the residents of both communes characterise concurrent possession by these communes. The commune of Cristinacce then appeals to the Court of Cassation.
Before the Court of Cassation, the commune of Cristinacce raises several arguments. It argues in particular that the cour d'appel did not find any material act emanating from the commune itself, but only acts of its residents. However, according to it, possession of a communal property by a commune can only result from acts performed by the organs of the commune (mayor, municipal council), and not by mere residents. Moreover, it argues that the plots are not all planted with chestnut trees and that some trees belong to residents of Cristinacce.
The Court of Cassation dismisses the appeal. It validates the reasoning of the cour d'appel: the acts of enjoyment performed by the residents of a commune may characterise possession by that commune of a communal property, concurrently with another commune. In other words, the possession of the commune can be established by individual acts of its residents, without the need to demonstrate a formal act of the town hall. What few people know is that this solution applies even if the residents of the two communes act without coordination.
The Reasoning of the Court — Analysed
To understand this decision, we must go back to the concept of possession (exercise of factual power over a thing, with the intention of behaving as the owner). In property law, prolonged possession may, under certain conditions, allow the acquisition of ownership by usucapion (adverse possession, i.e., becoming the owner after having possessed for a certain time, generally 30 years for land).
The difficulty here is that the property is a communal property (property belonging to a commune). The question was whether the possession of a commune can be proven by the acts of its residents. Article 2228 of the Civil Code (old, now article 2255) defines possession as "the detention or enjoyment of a thing or right which we hold or exercise by ourselves, or by another who holds or exercises it in our name." The judges interpreted this text by considering that the residents, as members of the commune, act on its behalf when they enjoy communal properties.
The commune of Cristinacce invoked the absence of a material act emanating from the commune itself. But the Court of Cassation considered that the cour d'appel had sovereignly assessed the facts by holding that the acts of the residents (collecting chestnuts, cutting wood) were sufficient to characterise the possession of the commune. However, note: this possession must be continuous, peaceful, public, unequivocal, and as owner (conditions of article 2261 of the Civil Code).
In clear terms, the Court of Cassation confirmed that the possession of a commune over a communal property can result from the collective use made by its residents, without the need to demonstrate a title (deed of ownership) or a formal act of the town hall. This applies even if the commune has never explicitly claimed the property. In other words, if the residents of a commune use a piece of land as if it were communal, the commune can be recognised as having concurrent possession.
This decision is in line with consistent case law that recognises that communal properties can be possessed by the commune through its residents. It is neither a reversal nor a major evolution, but a classic application of the rules of possession.
What This Changes for You — Practically
This decision has important practical implications, whether you are an owner, tenant or real estate professional.
For landlord owners: If you own land adjoining a communal property, you must be vigilant. If residents of the commune regularly use your land (e.g., to pick mushrooms or walk their dogs), they could, in the long run, contribute to establishing concurrent possession by the commune. undefined, I have come across cases where owners in Le Cannet have lost entire plots because they had not fenced their land and the commune had eventually come to consider it as communal. How to react? You must clearly demarcate your property and stop any unauthorised use.
For buyers: Before buying a property, check whether it is not claimed by a commune. If acts of enjoyment by residents have been established for more than 30 years, the commune could claim ownership. In Mandelieu, for example, a buyer found himself unable to build on land that the commune considered communal. If you are in this situation, you must require the seller to provide a clear title of ownership and, if necessary, take out legal protection insurance.
For co-owners: Communal properties are often used by neighbouring co-ownerships (car parks, gardens). If co-owners use communal land without right, they could, through their collective use, contribute to the possession of the commune. But conversely, if the commune allows it, it could lose its right of ownership by extinctive prescription (loss of a right by non-use).
For real estate professionals: Estate agents and notaries must be particularly attentive during transactions. A piece of land used by residents for decades may be considered communal, even if it appears on the cadastre as private property. A concrete example: in Le Cannet, a 500 m² plot used as an informal communal path was successfully claimed by the commune after 30 years of use, causing a loss in value of €150,000 for the owner.
Four Tips to Avoid This Type of Dispute
- Fence and mark your property: Install "Private Property" signs and a visible fence. This interrupts third-party possession and prevents collective use from being interpreted as communal possession.
- Have disturbances recorded by a bailiff: If residents enter your land, have a bailiff's report (official document recording the facts) drawn up and file a complaint for trespass. Keep these pieces of evidence.
- Check the cadastre and the origin of ownership: Before buying, ask the seller for a title of ownership going back more than 30 years. Consult the cadastral plan to verify boundaries. If in doubt, ask the town hall about the possible communal nature of the property.
- Negotiate an agreement with the commune: If your land is used by residents (access path, spring), sign a usage agreement with the commune to recognise your right of ownership and define the conditions of use.

Further Reading: Related Case Law and Developments
This decision is part of a series of judgments of the Court of Cassation that recognise the possession of communal properties through residents. For example, in a judgment of 3 November 1988 (No. 86-14.666), the Court held that "the possession of a communal property by the commune may result from the use made by the residents." The 2005 decision confirms this approach.
Conversely, a decision of 12 July 2000 (No. 98-18.975) had seemed to require a formal act of the commune to characterise its possession. But the 2005 judgment clarifies that this is not necessary: the acts of the residents suffice. This case law is therefore favourable to communes that wish to have their ownership recognised over land used for a long time by the population.
The current trend of the courts is to facilitate proof of possession by communes, which may worry private owners. It is therefore essential to react quickly if you notice collective use of your land. What few people know is that adverse possession (30 years) can operate even if the commune has no title: use is sufficient.
Summary and Next Steps
FAQ:
Q: Can I lose my land if residents have used it for more than 30 years?
A: Yes, if the commune can prove that this use is continuous, peaceful, public, unequivocal, and as owner. You must act to stop the use.
Q: What should I do if the commune claims my land?
A: Consult a lawyer specialising in property law. You can bring an action for recovery of ownership (legal action to have your right recognised) and claim damages for disturbance of enjoyment.
Q: Can a simple path used by residents become communal?
A: Yes, if the use is regular and lasts for 30 years. This is called adverse possession. Have the use recorded and, if necessary, bring an action to have your ownership recognised.
Q: How can I prove my ownership?
A: By a title of ownership (notarial deed), the cadastre, or witness statements. If you have no title, you can invoke your own possession (if it has lasted for more than 30 years).
Checklist:
