Tree Trimming: How to Force a Neighbor to Cut Overhanging Branches

A neighborhood dispute over vegetation can quickly turn a peaceful garden into a source of daily stress. Whether it is tree branches invading your property, dead leaves clogging your gutters, or a loss of natural light in your living room, French law strictly regulates neighborhood relations regarding tree trimming. Understanding your rights and the steps to follow is essential to resolving this situation calmly while preserving, as much as possible, a good relationship with your neighbors. Here is the complete guide from AvocatAI to legally compel a neighbor to cut their branches.

The Legal Framework of Tree Trimming in French Law

The French Code civil (Civil Code) regulates planting distances and trimming obligations very precisely to guarantee social peace between property owners. Contrary to popular belief, you do not have unlimited rights over what overhangs onto your property.

Legal Planting Distances (Article 671 of the Civil Code)

Before discussing tree trimming, you must check whether your neighbor's trees are planted at the regulatory distance. Unless there are specific local regulations (such as a plan local d'urbanisme or PLU [local urban local plan] or règlement de copropriété [co-ownership regulations]) or recognized constant local customs, national law sets strict limits:

• Trees and shrubs with a height greater than 2 meters must be planted at a minimum distance of 2 meters from the dividing line between the two properties.
• Plantings with a height of 2 meters or less must be located at a minimum distance of 0.50 meters (i.e., 50 centimeters) from the dividing line.

The distance is measured from the center of the tree trunk to the dividing line of the properties. The height is measured from the ground to the highest point of the tree.

The Absolute Prohibition on Cutting Your Neighbor's Branches Yourself (Article 673 of the Civil Code)

This is the golden rule of tree trimming law in France, which is often misunderstood and yet a source of heavy penalties: under no circumstances should you cut the branches that overhang onto your property yourself.

Article 673 of the Code civil explicitly states: “He on whose property the branches of the neighbor's trees, shrubs, and bushes extend may compel the neighbor to cut them.”

This text establishes two fundamental principles:

1. The right to demand trimming is imprescriptible: Even if the branches have overhung for 30 years or more, you retain the right to demand their trimming. The neighbor cannot invoke a 30-year prescription (prescription trentenaire) to escape this obligation.

2. The prohibition of self-justice: If you cut your neighbor's branches yourself without their written agreement, you commit a voie de fait (willful trespass/illegal act). Your neighbor could turn against you and claim damages in court, especially if the unauthorized cutting damaged the health of the tree or harmed its aesthetics.

Important Note: This same Article 673 specifies that if roots, brambles, or twigs encroach onto your land, you have the right to cut them yourself at the boundary line, without needing the authorization of the neighbor or a judge.

The Special Case of Tenants and Co-ownerships

Who has to pay and maintain?

• If your neighbor is a tenant: It is up to the owner of the neighboring property to assume responsibility for trimming the trees on their land. However, the routine maintenance of private gardens (trimming hedges, shrubs) is part of the charges récupérables (recoverable charges) and réparations locatives (tenant repairs) borne by the tenant (Decree No. 87-712 of August 26, 1987). In the event of a dispute, your action must target the landlord (propriétaire bailleur), who is the guarantor of respect for the property of others.
• *If you live in a co-ownership (copropriété): The rules of distance and trimming also apply between private lots, but they are often governed by the règlement de copropriété, which can be stricter than the Code civil. If the trees belong to the common areas (parties communes), you must contact the syndic de copropriété* (property manager).

Step-by-Step Practical Procedures to Force Your Neighbor to Trim

Faced with a recalcitrant or negligent neighbor, you must follow a methodical and graduated procedure. Acting in a disorganized or aggressive manner could weaken your case in the event of legal recourse.

Step 1: Dialogue and Friendly Approach (Common Sense First)

Before taking any formal steps, always prioritize dialogue. Go meet your neighbor or slip a polite note into their mailbox. Calmly explain the inconvenience caused (loss of light, humidity, risk of branches falling on your roof).

Propose to agree together on a date for the work. If the neighbor is elderly or has physical difficulties, offer to help them find a professional or to allow access to your land if this makes the trimming easier.

Step 2: Sending a Formal Letter of Demand (Mise en Demeure)

If oral dialogue remains unproductive or if your neighbor ignores your requests, you must formalize your demand.

Send a formal letter of demand, known as a mise en demeure, via Lettre Recommandée avec Accusé de Réception (LRAR - Registered Letter with Acknowledgment of Receipt). This letter must contain:

• A recall of the facts (dates of your previous verbal requests).
• A precise description of the inconvenience caused.
• The citation of Article 673 of the Code civil.
• A summons to carry out the trimming work within a reasonable timeframe (generally 15 to 30 days from receipt of the letter).
• A statement that, failing execution, you will initiate legal proceedings.

Carefully keep a copy of the letter and the signed acknowledgment of receipt.

Step 3: Mandatory Recourse to a Justice Conciliator

Since October 1, 2023 (Decree No. 2023-357), for this type of neighborhood dispute, recourse to an amicable resolution method is mandatory before you can petition the Tribunal Judiciaire (Judicial Court). If you skip this step, your legal claim will be ruled inadmissible.

You must refer the matter free of charge to a Conciliateur de Justice (Justice Conciliator). To do this:

1. Find a conciliator near you (via the website conciliateurs.fr or through your local town hall).

2. Submit a file explaining the dispute with your supporting documents (photos, copy of the mise en demeure).

3. The conciliator will convene both parties to a meeting to find an amicable written agreement (a constat d'accord), which can be approved by a judge to have enforceable status.

Step 4: Petitioning the Tribunal Judiciaire

If conciliation fails (the neighbor does not show up or refuses any agreement), you must then petition the Tribunal Judiciaire (Judicial Court, or its local chamber, the chambre de proximité) of the place where the property is located.

For this procedure:

• The assistance of a lawyer (avocat) is not mandatory but is highly recommended if the case is complex.
• You will ask the judge to order your neighbor to proceed with the trimming under an astreinte (daily penalty fine, for example, 50 € per day of delay).
• You can also claim damages if you prove direct and certain harm (broken gutters, damaged roof, abnormal loss of sunlight).

Deadlines, Costs, and Key Figures to Remember

To successfully carry out your procedures, here are the essential temporal and financial benchmarks:

• 2 meters: The minimum distance from the dividing line for trees over 2 meters in height.
• 0.50 meters: The minimum distance for trees or shrubs under 2 meters in height.
• 15 to 30 days: The usual timeframe to grant your neighbor in the mise en demeure letter to carry out the trimming work.
• 0 €: The cost of referring a case to a conciliateur de justice (the procedure is entirely free).
• 150 € to 300 €: The average cost of a constat de commissaire de justice (formerly huissier - bailiff's official report) if you wish to have the encroachment of the branches officially recorded before the trial. This cost can be charged to the losing neighbor under Article 700 of the Code de procédure civile (Code of Civil Procedure).
• 10 € to 100 € per day: The average amount of the daily penalty fine (astreinte) that a judge can order against the recalcitrant neighbor to force them to execute the work.
• 5 years: The limitation period (prescription) to take legal action in the event of an abnormal neighborhood disturbance (trouble anormal de voisinage) related to the height or location of trees (although the right to trim under Article 673 remains imprescriptible).

Concrete Examples of Tree Trimming Disputes

Example 1: The Martin Family's Century-Old Oak

The Martin family owns a house with a garden adjacent to that of Monsieur Bernard. A huge oak tree located on Monsieur Bernard's land has large branches overhanging the Martins' terrace. These branches block sunlight, and dead leaves constantly clog the Martins' gutters, causing water infiltration in their garage.

Monsieur Bernard refuses to cut the branches, claiming that the tree is a century old and part of the landscape. The Martin family has the encroachment recorded by a commissaire de justice (cost: 220 €), then contacts a conciliator. Faced with Monsieur Bernard's persistent refusal during conciliation, the Martins petition the Tribunal Judiciaire.

The judge strictly applies Article 673 of the Code civil: he orders Monsieur Bernard to have the branches overhanging the Martin property trimmed by a professional within 2 months, under penalty of an astreinte of 30 € per day of delay. Monsieur Bernard is also ordered to pay 800 € in damages for the cost of cleaning the gutters and loss of enjoyment, as well as to refund the 220 € in commissaire de justice fees.

Example 2: The Tenant and Sophie's Thuja Hedge

Sophie owns a suburban house that she rents to a young couple for 950 € per month. Sophie's neighbor complains that the thuja hedge planted on Sophie's land overhangs onto his property and has reached 3 meters in height, even though it is located only 40 centimeters from the fence.

The neighbor contacts Sophie's tenants directly to demand the trim. The tenants, not being the owners, forward the request to Sophie. As the landlord, it is up to Sophie to act because the hedge is planted at a non-regulatory distance (less than 50 cm from the boundary). Sophie must bear the costs of lowering the hedge to 2 meters in height (tree surgeon cost: 450 €). If the hedge had been correctly planted more than 2 meters from the boundary, the annual maintenance trimming would then have been the responsibility of the tenants as part of routine garden maintenance.

Mistakes to Avoid

• Cutting the branches yourself without written agreement: This is the most common mistake. Even if the neighbor turns a deaf ear, entering their property or cutting the branches from your garden without their written consent exposes you to prosecution for trespass (violation de domicile) or damage to another's property.
• Ignoring local urban planning rules (PLU): Before starting procedures based on the Code civil, always check with your town hall (mairie) to see if there is a specific municipal decree, local custom, or Plan Local d'Urbanisme (PLU). Some tree species are locally protected, and their trimming may be subject to authorization.
• Going directly to court without going through conciliation: Since the 2023 reform, the absence of a prior amicable conciliation attempt will result in the immediate rejection of your case by the judge, making you lose several months of proceedings.
• Failing to document the dispute: Do not rely solely on verbal assertions. Take high-quality photos from different angles, note the dates of your steps, keep all correspondence, and request written testimonies from neighbors if the nuisance is shared.

FAQ (Frequently Asked Questions)

My neighbor refuses to trim because it might kill their tree. What does the law say?

Article 673 of the Code civil is a matter of public policy (ordre public) and is absolute. The right to cut overhanging branches does not yield to the risk of the tree dying. The judge will order the trimming even if it compromises the survival or aesthetics of the neighbor's tree. It is up to the owner of the tree to hire a professional tree surgeon to carry out the operation under the best possible horticultural conditions.

Can I pick and keep the fruit from the neighbor's branches that overhang onto my property?

No. According to Article 673 of the Code civil, fruits hanging from the neighbor's branches still belong to the owner of the tree. You do not have the right to pick them directly from the branches overhanging your property. On the other hand, if these fruits fall naturally onto your ground, they become your property, and you can freely gather and consume them.

Who pays for trimming costs if the branches overhang onto a public road?

If the branches of a private tree overhang onto a street, sidewalk, or public path, it is up to the mayor, under their traffic police powers (Article L. 2212-2-2 of the Code général des collectivités territoriales [General Code of Local Authorities]), to issue a formal demand to the owner to trim. If the owner does not carry out the work, the municipality can have it carried out automatically at the owner's expense.

What should I do if the neighbor's tree threatens to fall on my house?

If the tree presents an imminent danger of falling (split trunk after a storm, uprooted tree), it is no longer just a question of trimming but of public safety. You must immediately contact your town hall. The mayor can issue a danger order (arrêté de péril) to compel the owner to fell or secure the tree urgently. In parallel, notify your home insurance company.
