Disputes over shared hedges are a common reason for court proceedings before the Nice and Grasse judicial courts. The independent building expert steps in to record breaches of the regulatory height limit, measure planting distances and assess neighbourhood disturbances. Cassini Expertise (Antibes, 04 22 46 06 04) supports property owners and co-owners through these technical disputes.
Legal Framework for Boundary Plantings: Article 671 of the Civil Code
Article 671 of the Civil Code sets out the rules governing plantings on a property boundary. The first paragraph requires a minimum planting distance of two metres for tall trees, measured from the boundary line to the centre of the trunk. The second paragraph allows planting closer than two metres, but then limits the maximum height to two metres, measured from the ground to the top of the plant.
These provisions apply in the absence of established local custom or a specific regulation. The Nice judicial court, like the one in Grasse, systematically examines whether a deviating local custom exists before applying the Civil Code’s requirements. The building expert verifies the actual planting distance through a joint measurement and records the actual height of the plants concerned.
Measuring the Planting Distance
The legal distance is measured from the boundary line to the centre of the trunk or the base of the hedge. The expert uses a laser or manual tape measure to establish this measurement precisely. Where a party wall exists, the boundary corresponds to the wall’s median axis. On bare land, prior boundary surveying by a licensed land surveyor is often necessary to determine the exact limit.
Cassini Expertise does not carry out boundary surveys, which are reserved for licensed land surveyors (géomètres-experts). The building expert’s involvement takes place after the plot boundary has been established, to record whether the plantings comply with legal requirements.
Measuring the Regulatory Height
Height is measured from the ground level of the neighbouring property to the top of the plant. On flat ground, the measurement is taken vertically. On sloping ground, the expert measures the height perpendicular to the natural ground level of the neighbouring plot, in line with the Court of Cassation’s settled case law. The instruments used include a laser rangefinder with a built-in inclinometer, allowing precise readings even on tall vegetation.
Obligations of the Hedge Owner
The owner of a hedge planted less than two metres from the boundary must keep its height at two metres or less. This obligation is continuous and permanent. A breach recorded by a bailiff or expert constitutes an abnormal neighbourhood disturbance, triggering civil liability under Article 1240 of the Civil Code, applicable as soon as damage is demonstrated.
The Neighbour’s Right to Trim
Article 673 of the Civil Code grants the neighbouring owner the right to compel their neighbour to cut back branches overhanging their land. This right is exercised through a formal notice, and, if refused, through legal action before the competent judicial court. The judge then orders the trimming at the planting owner’s expense. The court-appointed expert assessment precisely identifies the plants concerned and proposes a timetable for the work suited to pruning seasons.
Penalties for Failing to Respect the Distance Rules
The neighbour has the right to bring an action for removal or uprooting of non-compliant plantings. This action is not subject to any time-bar for as long as the plantings remain. The judge may order outright removal or, depending on the circumstances, require drastic pruning to keep the plants below the regulatory height. The technical expert assessment informs the court on the feasibility and cost of each solution.
Specific Rules for Municipalities in the Alpes-Maritimes
The municipalities of Nice, Antibes, Cannes, Grasse, Cagnes-sur-Mer, Valbonne and Mougins apply the Civil Code’s provisions in the absence of a documented, contrary local custom. Local urban plans (PLU) may impose additional requirements regarding green spaces, but generally do not override the distance rules set out in Article 671.
Areas classified as protected natural zones or within a forest fire risk prevention plan (PPRIF) may require mandatory brush clearing within 50 metres of buildings, independently of boundary rules. The building expert distinguishes these regulatory obligations from neighbourhood disputes falling under civil law.
Judicial Expert Assessment of Shared Hedges: Methodology
The expert appointed by the Nice or Grasse judicial court proceeds in stages: summoning the parties, a joint on-site visit, measurement of distances and heights, geo-referenced photographic records, and analysis of planning documents and title deeds. The expert’s report factually describes the findings, cites the applicable legal texts, and answers the questions raised in the appointment order.
On-Site Visit
The joint visit allows the parties to present their arguments and evidence. The expert measures distances and heights in the presence of the parties or their representatives. Lawyers frequently attend these proceedings to ensure both sides are heard. The site visit record captures each party’s statements, the measurements taken, and everyone’s observations.
Drafting the Report
The expert’s report details the methodology used, the measuring instruments employed, and the weather and access conditions on site. Measurements are shown on a site plan with a legend and scale. Dated, captioned photographs illustrate the findings. The technical conclusions answer the judge’s questions precisely, without ruling on matters of law, which remain the court’s exclusive competence.
Court Proceedings Before the Judicial Court
The claimant summons their neighbour before the judicial court with jurisdiction over the property’s location: the Grasse judicial court for Antibes, Cannes, Grasse and surrounding municipalities; the Nice judicial court for Nice and the eastern coastline. The procedure requires mandatory representation by a lawyer.
Interim Relief and Provisional Measures
The interim relief judge (juge des référés) may order an expert assessment or protective measures in cases of urgency or manifestly unlawful disturbance. Interim proceedings allow for a swift provisional decision, which can be appealed before the Aix-en-Provence Court of Appeal.
Judgment on the Merits
The judicial court rules after the investigation, the hearing and deliberation. The judgment may order trimming or removal, set a deadline for compliance under penalty, and order payment of court costs and non-recoverable legal fees (Article 700 of the Code of Civil Procedure). An appeal may be lodged before the Aix-en-Provence Court of Appeal within one month of notification of the judgment.
Cassini Expertise’s Role in Shared Hedge Disputes
Cassini Expertise acts as a court-appointed expert under a court order, or as an amicable expert instructed by one of the parties. An amicable expert assessment, carried out before any proceedings, objectively establishes the technical situation and encourages an amicable settlement. A judicial expert assessment takes place within ongoing legal proceedings.
The expert does not carry out boundary surveys, which remain the exclusive responsibility of the licensed land surveyor. The expert relies on existing survey plans, or waits for them to be established, before carrying out distance measurements. The assessment remains strictly technical and neutral, guaranteeing fairness and impartiality to both sides.
Preventing Disputes: Best Practices
Dialogue between neighbours is the first step in prevention. An amicable formal notice sent by registered letter with acknowledgement of receipt, recalling the legal obligations and proposing a reasonable deadline for compliance, is often enough to secure the trimming requested. If this fails, an amicable expert assessment objectively establishes the situation before any costly legal proceedings.
Consulting a lawyer specialising in property law beforehand allows you to assess how solid the case is and the chances of success. Legal costs, including lawyer’s fees, expert assessment fees and court costs, warrant a prior cost-benefit analysis. The building expert provides a precise costing of trimming or removal work, allowing you to anticipate the amount of any potential award.
