Party Wall of a Hedge: When Proof of Location Is Lacking (Cass. civ. 1970)

Picture the scene: you have just bought a charming villa in Mandelieu-la-Napoule, with a beautiful laurel hedge running along the neighbour's land. Everything seems idyllic until the day your neighbour tells you that the hedge is his, that it is planted on his plot and that he intends to pull it up. You are convinced otherwise, but how can you prove it? Hundreds of owners ask themselves this question every year, whether in Le Cannet, Grasse or elsewhere.

The decision of the French Supreme Court of 13 February 1970 (No. 68-13.444) gives a clear answer: the presumption of party wall status does not apply automatically. It must still be shown that the hedge is planted exactly on the boundary line. But what difference does that actually make?

In this article, I will tell you the story behind this judgment, break down the reasoning of the judges and, above all, give you practical keys to avoid or resolve a party wall dispute. Whether you are an owner, tenant or property professional, these lessons will be useful to you.

The facts: a story that happens every day

Mr X, an owner in Mandelieu, and his neighbour Mr Y have been in conflict for years. The cause? A hedge of shrubs which, according to Mr Y, encroaches on his property. Mr X, for his part, thinks it is a party hedge. The dispute starts with a simple discussion, then escalates: Mr Y cuts a few branches, Mr X protests. Finally, each party goes to court to have their rights recognised.

Before the trial judges, Mr X invokes the presumption of party wall status provided for in Article 653 of the Civil Code. This article provides that, unless proved otherwise, any wall, hedge or ditch located between two inheritances is presumed to be party. But note: this presumption assumes that the hedge is established on the boundary of the two properties. However, in this case, nothing made it possible to determine with certainty exactly where the dividing line ran. The title deeds were vague, and the condition of the premises provided no clear clue.

After an initial unfavourable decision, Mr X appeals. The Court of Appeal, to decide, relies on the actual area of the plots as shown in the notarial deeds. It deduces that the hedge cannot be a party hedge. Mr X then appeals to the Supreme Court, arguing that the judges violated the presumption of party wall status. But the Supreme Court dismisses his appeal, upholding the reasoning of the trial judges. In short, they correctly applied the rule: in the absence of proof of the exact location of the boundary, they were able to refer to other elements, such as area.

The reasoning of the court — broken down

To fully understand this judgment, we must go back to the legal basis. Article 653 of the Civil Code establishes a simple presumption of party wall status for walls, hedges and ditches separating two properties. But this presumption is not automatic: it only applies if the structure is "on the boundary" of the two properties. In other words, if the hedge is entirely on the land of one owner, it belongs entirely to that owner.

In this case, Mr X argued that since the hedge was a party hedge, the presumption should apply. But the judges considered that the presumption could not be invoked because it was not proven that the hedge was established on the boundary. They therefore examined the deeds and noted that the areas mentioned did not correspond to the location claimed by Mr X. They were able, without contradicting themselves, to disregard the presumption and decide based on the actual area of the plots.

What few people know is that the burden of proof lies on the person who asserts party wall status. If you claim that a hedge is a party hedge, it is up to you to prove that it is on the boundary. In the absence of proof, the judges may use any available evidence: deeds, plans, cadastre, boundary survey, witness statements. Here, they chose the actual area, which the Supreme Court held to be lawful.

Note however: this decision does not call into question the presumption of party wall status itself. It simply clarifies the conditions for its application. It is a confirmation of previous case law, not a reversal.

What this changes for you — practically

Practically, whether you are a landlord owner, tenant or buyer, this decision has practical implications. Here is what to remember by profile:

• Landlord owner: If you rent a villa in Le Cannet with a party hedge, you must be able to prove that the hedge is indeed on the boundary. In the event of a dispute with the tenant or neighbour, title deeds and a recent boundary survey are your best allies. Without this, you risk losing party wall status.
• Buyer: Before buying a property, check the condition of the boundaries. If a hedge runs along the property, ask the seller to provide a boundary survey certificate or a party wall attestation. undefined, I have come across cases where the lack of proof has cost thousands of euros in legal fees.
• Co-owner: In a co-ownership, hedges separating private lots are often party hedges. But if a co-owner plants a hedge set back, it belongs to them. Do not assume party wall status without checking the co-ownership rules and deeds.
• Tenant: As a tenant, you do not own the hedge, but you must respect the boundaries. If you plant a hedge, make sure you do not encroach on the neighbour's land, otherwise you may have to remove it at your own expense.

A worked example: imagine a plot in Le Cannet of 500 m². If the disputed hedge occupies a strip of 5 metres by 20, i.e. 100 m², the value of this strip could be estimated at 100 m² x €300/m² = €30,000. An unresolved dispute can lead to a significant loss of value.

If you are in this situation, you must act quickly. Consult a lawyer lawyer to assess your evidence. A simple registered letter to your neighbour may sometimes suffice, but often mediation or a boundary action will be necessary.

Four tips to avoid this type of dispute

• Have an amicable boundary survey carried out before any planting. A chartered surveyor will precisely delimit your property. Cost: €1,000 to €2,000, but this avoids much higher legal costs. Example: in Mandelieu, a recent boundary survey avoided a €10,000 lawsuit.
• Keep all your title deeds and notarial acts. They often mention boundaries and areas. In the event of a dispute, they are essential evidence. Digitise them and keep several copies.
• Regularly photograph the boundaries of your land. A dated photo (with a newspaper or geolocation app) can serve as evidence. If the neighbour moves a hedge, you will have a record.
• If in doubt, do not trim the hedge without agreement. If you cut branches of a hedge you believe to be party, you could be accused of trespass. Better to first verify ownership.

Further reading: related case law and developments

The 1970 decision is part of a consistent line of case law. As early as 1856, the Supreme Court held that the presumption of party wall status only applies to structures located on the boundary (Civ., 3 May 1856). More recently, a 2012 judgment (No. 11-18.871) recalled that proof of party wall status may be adduced by any means, including strong, precise and consistent presumptions.

The current trend is to favour legal certainty by requiring solid evidence. Courts are increasingly reluctant to be satisfied with mere allegations. This means that in the future, owners will have to be more rigorous in documenting their boundaries.

For property professionals, this case law is a reminder: when selling, it is prudent to include a clause relating to easements and party walls, and to provide an accurate condition survey.

Summary and next steps

FAQ:

• How to prove that a hedge is a party hedge? You must show that it is planted on the dividing line. A boundary survey, a cadastral plan, deeds or witness statements can do this.
• What if the neighbour claims the hedge is theirs? Ask them for their evidence. If they have none, you can challenge them. Mediation is recommended before going to court.
• What if the hedge is entirely on my land? It belongs entirely to you. You can dispose of it freely, but respect planting distances from the boundary.
• Can I cut branches that overhang onto my land? Yes, but only if the hedge is party or belongs to the neighbour. In the latter case, you may cut the branches up to the boundary, but no further.
• What is the limitation period for party wall matters? Party wall status is not lost by the passage of time. However, the action to assert ownership is subject to a 30-year limitation period.
