Aggravation of Easement: Judges Freely Determine Compensation

Imagine: you own a house in Castelnaudary, with a lovely view of the Canal du Midi. One day, your neighbour decides to raise his garage, blocking your panorama and altering the drainage of rainwater. You are furious, but what does the law say? Can he do it? And above all, how do you obtain compensation?

This question is asked by hundreds of owners each year in the Toulouse region. The answer lies in one word: easement. An easement (a real property right burdening one land for the benefit of another) can be aggravated, but its beneficiary must then compensate the owner of the servient tenement. But who decides the amount and methods of this compensation?

A judgment of the Court of Cassation of 11 June 1974 (No. 73-11.365) provides a clear answer: it is the lower court judges who freely assess the methods of compensation. In other words, the local judge, who knows the territory and local customs, has the final say. Analysis.

The facts: a story that happens every day

In this case, the X spouses own a building in Toulouse, rue du Languedoc. Their neighbour, Mr Lapouge, owns the adjoining land. For years, easements of view (right to see into the neighbour's property) and drainage of water (right to allow water to flow onto the neighbour's land) burden the X spouses' building in favour of Mr Lapouge.

But one day, Mr Lapouge decides to carry out works: he enlarges his window (thus aggravating the easement of view) and modifies the slope of his roof, which changes the drainage of rainwater onto the X spouses' property. The latter, exasperated, sue him to have these nuisances removed.

The Tribunal de Grande Instance of Toulouse, and then the Court of Appeal, find that Mr Lapouge did not create new easements, but simply aggravated those already existing. The judges then order restoration works, as well as damages.

Mr Lapouge appeals to the Court of Cassation, arguing that the judges should have specified the exact methods of compensation. But the Court of Cassation dismisses his appeal: it recalls that the lower court judges have a sovereign power to assess these methods. In short, they can freely decide what must be done, without having to detail each step.

The court's reasoning — explained

The core of the judgment lies in one sentence: "The judges of the second degree sovereignly considered that the beneficiary of these easements had to repair the aggravation." What does this mean?

First, let us recall the legal basis: aggravation of an easement is an abnormal neighbourhood disturbance (exceeding the normal inconveniences of neighbourhood) which triggers the civil liability of its author under Article 1240 of the Civil Code (former Article 1382). This text provides that "any act of a person which causes damage to another obliges the person by whose fault it occurred to compensate for it."

But how to compensate? The law does not specify the methods: must the cause of the disturbance be removed? Pay an indemnity? Both? This is where the "sovereign power" of the lower court judges comes in. This power means that the appeal judges (or first instance judges) have full discretion to decide, according to the circumstances of the case, the form and amount of compensation. The Court of Cassation only reviews the legal characterisation of the facts, not the concrete assessment of the lower court judges.

In this case, the judges considered that removing the causes of the aggravation (demolishing the enlarged window, restoring the original drainage) was the appropriate solution. They could also have chosen a monetary indemnity. This sovereign power is a guarantee for litigants: the local judge, who knows the terrain, can adapt his decision to local realities.

However, this power is not absolute. Judges must give reasons for their decision and respect the adversarial principle (allowing each party to be heard). But once the decision is rendered, the Court of Cassation does not challenge it on the merits.

What this means for you — concretely

Whether you are an owner of a property in Toulouse or a tenant in Castelnaudary, this judgment has practical implications.

If you are the owner of the servient tenement (the one suffering the aggravation): you can claim compensation before the tribunal judiciaire. The judges have the power to order restoration works or damages. For example, if your neighbour aggravates a right of way by widening his gate, the judge can order him to narrow it. undefined, I have seen cases where the judge imposed an indemnity of €5,000 for loss of view, without works. It all depends on the facts.

If you are the owner of the dominant tenement (the one benefiting from the easement): you must be careful before undertaking works that aggravate the easement. Even if you do not create a new easement, you may be ordered to compensate. For example, if you raise your house in Toulouse and this increases the view over the neighbour, you may have to install blinds or pay an indemnity.

For purchasers: before buying a property, check existing easements. If the seller has already aggravated an easement, you might inherit the obligation to repair. Have a boundary survey carried out and consult the land registry.

For co-owners: the rules are similar. If private works aggravate an easement of the co-ownership, the managing agent can take legal action.

Four tips to avoid this type of dispute

• Consult the land registry and notarial deeds before any works: check the existence of easements (right of way, view, drainage) and their extent. A simple glance at the cadastral plan can avoid years of litigation.
• Discuss with your neighbour before starting: an amicable mediation costs less than a trial. Propose a written agreement on the methods of the works, possibly with an indemnity. For example, in Castelnaudary, an amicable agreement for an enlarged window with an indemnity of €1,000 avoided a 3-year trial.
• Call in a building expert to assess the impact of the works on the easements. An expert report can serve as evidence in court and guide the judge in his sovereign decision.
• Ensure you have liability insurance covering neighbourhood disturbances. In case of a judgment against you, your insurer may cover the damages, but check exclusions (e.g., undeclared works).

This 1974 judgment is part of a consistent line of the Court of Cassation. Already, in a judgment of 27 March 1968, the Court affirmed the sovereign power of lower court judges in matters of easements. More recently, a judgment of 12 May 2021 (No. 20-14.678) recalled that the assessment of the abnormal nature of a neighbourhood disturbance also falls within the sovereign power of lower court judges.

The trend is therefore stable: local judges are best placed to assess concrete situations, because they know local customs and the specificities of the terrain. This means that if you litigate in Toulouse, the Toulouse judge can take into account local practices (for example, the orientation of houses facing the canal) to fix the compensation.

On the other hand, the Court of Cassation does not hesitate to quash decisions that lack reasoning. So, if the lower court judges do not justify their choice, their decision may be overturned. This is a safeguard for litigants.

Frequently asked questions

Can I aggravate an easement of view without authorisation? No, without the consent of the owner of the servient tenement, you risk legal action. Even if the easement already exists, aggravation is unlawful.

What should I do if my neighbour aggravates an easement? Gather evidence (photos, bailiff's report) and send a formal notice. If nothing changes, bring the matter before the tribunal judiciaire. You can claim damages and/or restoration.

What is the time limit for taking action? The action for liability for neighbourhood disturbance is subject to a 5-year prescription from the day the damage became apparent (Article 2224 of the Civil Code). Do not delay.

How much does a lawsuit for aggravation of easement cost? Legal fees vary: expect between €1,500 and €5,000 for a simple procedure, more if an expert is appointed. But mediation can cost less than €500.

Can the judge order demolition of the works? Yes, that is a possible remedy. The lower court judges have this sovereign power, but they often favour less radical solutions (indemnity, compensatory works).
