Right of view: when a window becomes an acquired right by prescription

You have just bought a house with a terrace in Montpellier, in the Arceaux district. The sun floods your living room, but one detail bothers you: your neighbour's window, opened twenty years ago, looks directly onto your garden. "It's just a light," he tells you. But you feel like you are being watched. Who is right? The question seems simple, but it has given rise to abundant case law. The decision of the Court of Cassation of 8 May 1973 (No. 71-14.774) provides a clear answer: it is for the trial judges to decide, on a case-by-case basis, whether an opening is a simple light or a genuine view. In other words, each situation is unique, and the judges have the final say.

In this article, I will tell you about this case as if you were there, break down the judges' reasoning, and above all give you the keys to avoid or resolve a neighbour dispute related to views. Because in Béziers as in Montpellier, these conflicts are frequent and can poison the life of a neighbourhood. So, how do you know if your neighbour can legally look into your home? And what should you do if you discover an open window without right? Follow the guide.

As a lawyer specialising in property law, I have seen cases where a simple dormer window became, after thirty years, an irreversible right of view. The 1973 decision is a key piece to understand this mechanism. But be careful: everything depends on the facts. And it is the trial judges, not the Court of Cassation, who assess them with sovereign power. Analysis.

The facts: a story that happens every day

Imagine: in Montpellier, in the historic Écusson district, two adjoining properties. On one side, Mr and Mrs A; on the other, Mr and Mrs B. For decades, an opening has existed in the wall of Mr and Mrs B's house, overlooking the courtyard of Mr and Mrs A. Mr and Mrs B use this opening to get fresh air and look outside. But Mr and Mrs A consider that it infringes their privacy. They sue Mr and Mrs B to have it declared an unlawful view and demand its removal.

The Tribunal de grande instance of Montpellier hears the case. Mr and Mrs B defend themselves by invoking thirty-year prescription: according to them, they have acquired by prescription a right of view over Mr and Mrs A's land, since the opening has existed for more than thirty years without challenge. Mr and Mrs A retort that it is only a "fixed light with fixed glazing", that is, an opening that does not allow one to see into the neighbour's property (like a fixed window with frosted glass) and therefore cannot constitute a right of view.

The tribunal rules in favour of Mr and Mrs B: it finds that the opening is a genuine view, and that thirty-year prescription has taken effect. Mr and Mrs A appeal. The Montpellier Court of Appeal upholds the judgment. Mr and Mrs A then appeal to the Court of Cassation. But the Court of Cassation dismisses their appeal. It reminds that the determination of the nature of openings (light or view) falls within the sovereign appreciation of the trial judges. In short, it was the judges in Montpellier who examined the premises, heard the witnesses, and decided that the opening was a view. The Court of Cassation cannot review this finding of fact.

What to remember: Mr and Mrs B won because they were able to prove that the opening had existed for more than thirty years and that it allowed a direct view over the neighbouring land. The judges sovereignly considered that it was not a simple light. And this decision is final.

The reasoning of the court — broken down

To understand the decision, we must go back to the texts. The Civil Code distinguishes two types of openings: the "light" (Article 676) and the "view" (Article 678). A light is an opening that does not allow one to look into the neighbour's property (for example: a window with fixed glazing, located more than 2.60 metres above the ground). A view, on the contrary, allows one to see directly into the neighbouring land. To create a view without title, legal distances must be respected (at least 1.90 metres for a straight view, 0.60 metres for an oblique view). If these distances are not respected, the neighbour can require the removal of the opening or the filling of the lights.

But there is a way to acquire a right of view even without respecting these distances: acquisitive prescription (Article 690 of the Civil Code). If the opening has existed for thirty years without challenge, the owner of the land benefiting from it may acquire the right to maintain it. This is what Mr and Mrs B invoked.

The reasoning of the trial judges was as follows: they examined the characteristics of the opening (dimensions, height, orientation, type of glazing) and concluded that it was a view, not a simple light. Then, they verified that this view had existed for more than thirty years, which was established by witness statements and old photographs. Consequently, they held that Mr and Mrs B had acquired by prescription a right of view over Mr and Mrs A's land.

In its decision, the Court of Cassation does not question this analysis. It merely reminds the principle: the qualification of the opening is a question of fact, which falls within the sovereign appreciation of the trial judges. In doing so, it confirms the solution adopted by the Court of Appeal. There is neither reversal nor evolution: it is a classic application of the law of servitudes.

What few people know is that thirty-year prescription can apply even if the opening was created without title (for example, a window opened in violation of legal distances). But it must be proved that the opening was apparent and continuous. A view is apparent by nature, but if it is obscured for part of the prescription period, the term may be interrupted.

What this changes for you — concretely

This decision has direct implications for owners, buyers and co-owners. Here is what you should remember according to your situation.

If you are the owner of a property with a view over the neighbour: Check the age of this view. If it has existed for more than thirty years without challenge, you may have acquired a servitude by prescription. But be careful: this is not automatic. The opening must be a genuine view (and not a simple light) and you must be able to prove it. For example, in Béziers, one of my clients had a window overlooking the neighbour's courtyard since 1945. He was able to demonstrate its age with period photographs and certificates. The judges recognised the prescription. On the other hand, if the opening has been modified (enlarged, moved), the term starts again from zero.

If you suffer from a view into your home: You can take legal action to have the view removed if it does not respect the legal distances AND if it is less than thirty years old. But if it is older, you will have to prove that it is not a view (simple light) or that prescription has not been acquired (for example, if the opening was obscured for a period). undefined, I came across a case where an opening had been blocked by a wall for twenty years, then reopened. The judges considered that the prescription had been interrupted. Result: the owner had to fill it in again.

If you are a buyer: Before buying a property, have a notary or lawyer check for any potential views over the neighbouring land. If a view exists without title and is less than thirty years old, you risk a lawsuit. Conversely, if you buy a property that benefits from a view acquired by prescription, this is a definite advantage. Ask for a specific clause in the deed of sale.

Example in figures: a view dispute can cost between €3,000 and €10,000 in legal costs (expert report, lawyer, proceedings). Prevention is better than cure.

Four tips to avoid this type of dispute

• Carry out a photographic inventory before any purchase or works. Take photos of all openings overlooking the neighbouring land, with date markers. This can serve as evidence in case of later challenge.
• Scrupulously respect the legal distances. For a straight view, allow at least 1.90 metres between the window and the boundary line. For an oblique view, 0.60 metres. If in doubt, consult a surveyor.
• Do not let thirty years pass without reacting. If your neighbour creates an unlawful view, act quickly. A registered letter with acknowledgement of receipt may be enough to interrupt the prescription. Do not delay, otherwise you risk losing your right.
• In case of a dispute, favour mediation. Before going to court, try an amicable solution. An agreement could provide, for example, for the installation of frosted glass or a blind. This avoids costs and tensions.

Further reading: related case law and developments

This 1973 decision is part of a consistent line of the Court of Cassation. We can cite the decision of 19 December 1969 (No. 68-12.405) which had already held that the qualification of an opening fell within the sovereign power of the trial judges. More recently, the decision of 12 September 2019 (No. 18-17.954) confirmed this principle, specifying that judges must take into account all circumstances: dimensions, height, orientation, use.

The trend of the courts is therefore to leave a broad scope for concrete assessment. This means that there is no "off-the-shelf" solution: each case depends on its facts. For the future, we can expect judges to be increasingly demanding regarding proof of age and the nature of the opening (photos, witness statements, bailiff's reports).

In conclusion, the 1973 decision remains a reference. It reminds us that the law of servitudes is a subtle balance between the right of property and neighbourly tolerance. If you are faced with a situation involving a view, remember that the trial judges are the masters of the game. It is up to you to provide them with the elements to win their conviction.

Checklist before taking action

• 1. Identify the type of opening: Is it a light (fixed glazing, height > 2.60 m) or a view (opening window, direct view)?
• 2. Estimate the age: How long has this opening existed? More than thirty years? Can you prove it?
• 3. Check the distances: Measure the distance between the opening and the boundary line. Does it respect the legal minima?
• 4. Gather evidence: Old photos, witness statements, notarial deeds, cadastral plans, bailiff's report.
• 5. Consult a lawyer: Before sending a letter or taking legal action, a professional can assess your chances and advise you on the best strategy.
