Four-Year Limitation Period: When a Local Authority's Irregular Encroachment Triggers the Time Limit

Imagine: you own a plot of land in Oullins, in the Lyon suburbs. One day, without warning, the local authority installs pipes or widens a road on your plot. You say nothing, for fear of conflict or out of ignorance. Years pass. Fifteen years later, you decide to claim compensation. Too late, you are told: your claim is time-barred. But from when does this time limit run? This is precisely the question that the Cour de cassation answered on 28 January 2003, in a ruling that remains authoritative.

This decision, rendered under number 01-02.514, concerns a conflict between owners and the Regional Council of Île-de-France, the department of Essonne, and a municipality. But its reasoning applies throughout France, including in Villeurbanne or Oullins. The principle is simple, but its consequences are severe: the four-year limitation period begins to run from the date of the generating event of the claim. For an irregular encroachment, this is the date of the taking of possession of the land.

Whether you are an owner, a landlord, or simply a citizen faced with a public project, understanding this rule can prevent you from losing your rights. Let us delve into the details of this case and see what it changes concretely for you.

The facts: a story that happens every day

The story begins in the 1960s-1970s. Mr Le Fort, owner of land situated within the territory of a municipality, consents to several transfers to private purchasers between 1969 and 1970. But in parallel, the municipality, without title or expropriation procedure, occupies part of this land to carry out public developments. For decades, nothing happens. Mr Le Fort's heirs, who become owners, discover one day that their land is being used by the local authority. In November 1994, they sue the municipality, the department and the region to obtain compensation for irregular encroachment (i.e., compensation for the illegal occupation of their property).

The municipality, for its part, raises the four-year limitation period: it argues that the owners' claim has been extinguished for more than four years. The court must therefore determine from which date this period runs. The owners argue that the starting point is the date of the claim for compensation, or at least the date on which they became aware of the encroachment. The municipality, on the other hand, argues that it is the date of the taking of possession, i.e., the years 1969-1970.

The case goes up to the Cour de cassation, which must decide a question of principle: for a claim against a public authority, does the four-year limitation period (provided for by the law of 31 December 1968) run from the generating event or from the knowledge of the damage? The answer is clear: it is the date of the generating event. In this case, the taking of possession of the land.

The reasoning of the court — analysed

The Cour de cassation relies on the law of 31 December 1968 on the limitation of claims against the State, departments, municipalities and public establishments. This law, in its Article 1, provides that all claims that have not been paid within a period of four years from the first day of the year following the year in which the rights were acquired are prescribed in favour of these authorities. But it is still necessary to know when the right is acquired.

The Court clarifies that, for claims arising from damage, the right is acquired on the date of the generating event of the damage. For an irregular encroachment, the generating event is the taking of possession of the land by the authority, and not the date on which the owner became aware of it. This reasoning is based on Article 1240 of the Civil Code (formerly 1382), which requires the person causing damage to compensate for it. But the Court adds that the four-year limitation period is a special limitation period, derogating from ordinary law, which can only be interrupted by a written claim addressed to the authority.

In this case, the owners brought legal proceedings in 1994, whereas the taking of possession dated back to 1969-1970. The four-year period was largely exceeded. The Court therefore confirms that the claim is time-barred. This solution may seem harsh, but it is settled: the owner must act quickly as soon as his land is occupied, on pain of losing all right to compensation.

What this changes for you — concretely

This decision has very concrete implications for all landowners. If you are the owner of land and a local authority (municipality, department, region, State) occupies it without your consent, you must act within four years of the start of the occupation. After this period, your claim is extinguished, even if you did nothing to allow it.

Take a numerical example: in Villeurbanne, an owner notes in January 2024 that the municipality has installed waste containers on part of his land since January 2021. If he does not claim compensation before 1 January 2025 (i.e., four years after the generating event), his claim is time-barred. He loses all right to compensation, even if the occupation continues.

For tenants, the situation is different: if you are a tenant and the municipality occupies the land, it is for the owner to act. But you can inform him. For purchasers, caution: if you buy land already occupied by a local authority, the limitation period may have already run. Check the date of occupation.

Finally, for co-owners, if the co-ownership is affected by an encroachment (e.g., passage of a public pipeline), the syndic must act on behalf of the syndicate within four years.

Four tips to avoid this type of dispute

• Monitor your land regularly. Visit it at least once a year, especially if you do not live on site. Take dated photos. Any abnormal occupation must be reported immediately.
• Send a written claim at the first sign of occupation. A registered letter with acknowledgement of receipt to the authority interrupts the limitation period. Keep a copy carefully.
• Consult a lawyer quickly. As soon as you become aware of an encroachment, even if you think it is temporary, a lawyer specialising in property law can assess your rights and advise you on the steps to take.
• Check the deeds of sale and title deeds. When purchasing land, ensure that no easement or public occupation exists. The notary can help, but it is also your responsibility to check the condition of the property.

Further reading: related case law and developments

This decision of the Cour de cassation is part of settled case law. Already, in a judgment of 22 November 1978 (No. 77-12.372), the Court had held that the starting point of the four-year limitation period is the date of the generating event. In 2003, it confirms and clarifies this principle for irregular encroachments.

Since then, the tendency of the courts has been to apply this time limit strictly. Local authorities systematically invoke the four-year limitation period to dismiss late claims. The judges are strict: even if the owner was unaware of the occupation, the limitation period runs from the taking of possession, unless there is fraud or concealment on the part of the authority (which is rare).

For the future, it is possible that the legislature will intervene to relax this rule, in particular by aligning the starting point with knowledge of the damage, as in ordinary law. But for now, the rule remains that of 2003: act quickly, or lose your rights.

In practice: what to do

Here is a checklist of actions to take if you discover an occupation of your land by a local authority:

1. Date the occupation. Gather all evidence (photos, witness statements, documents) to determine the start of the encroachment.
2. Send a written claim. Registered letter with AR to the authority, detailing the facts and requesting compensation or cessation of occupation.
3. Consult a lawyer. Within four years of the start of the occupation, to take legal action if necessary.
4. Do not delay. Every day that passes brings you closer to the limitation period. Do not wait until the period has expired to act.
