Party Wall: Construction without Consent and Limitation of Action – What Does the Court of Cassation Say?

Imagine: you own a house in Fréjus, with a party wall separating your garden from your neighbour's. One morning, you discover that this neighbour has demolished the wall to build a cellar in its place, without asking for your opinion. You feel wronged: this wall belongs to you in equal shares. You decide to take legal action. But how long do you have to act? And if the criminal proceedings are time-barred, can you still raise this ground on appeal? This is exactly the question the Court of Cassation decided in a judgment of 12 April 1972, number 70-13.213. This decision, although several decades old, remains a reference for all party wall disputes, particularly in the Var and Alpes-Maritimes. But what does this actually change for you?

The Facts: A Story That Happens Every Day

Mr. X, an owner in Fréjus, has a party wall with his neighbour, Mr. Y. Without authorisation, Mr. Y demolishes the wall to build a cellar in its place. Mr. X sues Mr. Y in the civil court, relying on Article 662 of the Civil Code (which prohibits a co-owner from demolishing a party wall without the other's consent). At first instance, Mr. Y raises a ground: the criminal action (for breach of building regulations) is time-barred. The court rejects this ground and finds against Mr. Y. He appeals. On appeal, Mr. Y seeks confirmation of the judgment (which is favourable to him on the merits). But he implicitly reasserts the limitation ground, based on his request for confirmation. The Court of Appeal upholds this ground and declares the action time-barred, thus inadmissible. Mr. X appeals to the Court of Cassation, arguing that the Court of Appeal violated Article 2223 of the Civil Code (which prohibits the judge from raising the limitation ground of his own motion) and the rights of the defence. The Court of Cassation dismisses the appeal: it holds that the Court of Appeal did not violate these provisions because the limitation ground had been raised at first instance and that Mr. Y, by seeking confirmation of the judgment, had implicitly reasserted it in his appeal submissions. In other words, the limitation ground may be invoked on appeal if it was already raised at first instance.

The Reasoning of the Court – Analysed

The Court of Cassation considers two issues: compliance with the prohibition in Article 2223 of the Civil Code (which provides that the judge cannot raise the limitation ground of his own motion) and the rights of the defence. In this case, the limitation ground for the criminal action had been raised by the neighbour at first instance. On appeal, his submissions merely sought confirmation of the judgment. But according to the Court, this request for confirmation necessarily implies the reassertion of all grounds underlying the first instance decision, including the limitation ground. Therefore, the Court of Appeal did not raise this ground of its own motion: it merely examined it because it was implicitly contained in the submissions. The lower court thus respected the rights of the defence, as the appellant (the wall owner) was able to argue this ground. In short, the Court of Cassation validates a common practice: an appellant who seeks confirmation of the judgment reasserts all grounds that were argued at first instance, even if they are not listed. This avoids unnecessary formalities, but note: this flexibility only applies if the ground was already raised at first instance. If the neighbour had never invoked the limitation before, he could not do so for the first time on appeal (subject to exceptions).

What This Changes for You – Practically

This decision has practical implications for owners, co-owners and property professionals. If you own a party wall and your neighbour carries out works without your consent, you must act quickly. Legal action (to stop the works or obtain damages) is subject to limitation periods: in civil matters, it is generally 30 years for real actions (such as claiming party wall status), but note actions in tort (5 years since the 2008 reform). If you are the neighbour who carried out the works, you may try to invoke the limitation of the criminal action (for example, if the works were done without planning permission, the public prosecution is time-barred after 6 years). But this ground must be raised at first instance, otherwise you risk not being able to reuse it on appeal. undefined, I have encountered cases where an owner in Hyères delayed acting against a neighbour who had raised a party wall without authorisation. The neighbour was able to invoke the limitation of the demolition action because the owner had waited over 30 years. Result: the wall remained. Concrete example: if you estimate that your neighbour's construction causes you €10,000 in damages, you must act within 5 years from the discovery of the damage. After this period, your action is time-barred.

Four Tips to Avoid This Type of Dispute

• Keep all documents relating to your property: deed of sale, plans, photos. In the event of a dispute over a party wall, they will allow you to prove the party wall status and the age of the constructions.
• Before carrying out works on an adjoining wall, have its party wall status confirmed by a chartered surveyor. If the wall is a party wall, you must obtain the written consent of your neighbour (Article 662 of the Civil Code). Mere tolerance is not enough.
• If you discover works by your neighbour that encroach on your property, react immediately. Send a registered letter with acknowledgment of receipt to mark your opposition. The longer you wait, the greater the risk of limitation.
• In the event of a dispute, consult a lawyer specialising in property law at the first signs of conflict. As this decision shows, the procedure is technical and compliance with limitation periods is crucial. A lawyer will help you raise the right grounds at the right time.

The solution of this 1972 judgment has been followed in other decisions. For example, the Court of Cassation held that the limitation ground may be invoked on appeal even if not expressly restated, provided the appellant seeks confirmation of the judgment (Civ. 3e, 13 March 2002, No. 00-18.163). Conversely, if the appellant formulates new submissions, he cannot rely on a limitation ground that was not raised at first instance (Civ. 3e, 25 January 2018, No. 16-26.130). The trend is therefore towards procedural flexibility, but with a requirement of fairness: the ground must have been argued at first instance. What few people know is that the judge may also raise limitation of his own motion if it is a matter of public policy (for example, limitation of criminal prosecution). But in civil matters, Article 2223 of the Civil Code prohibits the judge from doing so. Hence the importance of raising this ground yourself.

Key Points to Remember

• What to do if your neighbour builds without your consent on a party wall? React in writing as soon as possible. Consult a lawyer to take action before the limitation period expires (5 years for damages, 30 years for claiming party wall status).
• Can I invoke limitation on appeal if I did not do so at first instance? No, unless the limitation is a matter of public policy. You must raise this ground at the beginning of the proceedings.
• What is the time limit for taking legal action regarding a party wall? For a demolition action, it is 30 years from the construction. For damages, it is 5 years from the discovery of the damage.
• What does the neighbour risk by demolishing a party wall without authorisation? He may be ordered to restore the wall (under penalty) and to pay damages. Limitation may, however, prevent this.
• Do I necessarily need a lawyer? In party wall matters, the procedure is complex (especially on appeal). A specialised lawyer is strongly recommended to avoid losing your rights.
