Roots from a tree planted on your neighbour’s property are invading your wastewater or stormwater pipes. Blockages keep recurring, drain clearing becomes routine, and the question arises: who is liable? Who pays? What does the law say? Article 673 of the French Civil Code allows you to cut the roots yourself, but the process requires a prior diagnosis, a formal notice, and sometimes legal action before the Judicial Court of [Grasse](https://cassini-expertise.fr/grasse-secheresse-argile-fissures-donnees-officielles/) (for [Antibes](https://cassini-expertise.fr/antibes-secheresse-argile-fissures-donnees-officielles/), Cannes, Grasse) or Nice (for Nice and the eastern part of the Alpes-Maritimes).

## The right to cut roots at the property line

Article 673, paragraph 2, of the Civil Code states: “If it is the roots, brambles or twigs that extend onto the neighbouring property, the owner of that property has the right to cut them at the boundary line.” This is a personal right: you do not need the tree owner’s permission to cut roots that encroach on your property, provided you respect two technical and legal limits.

- **Cut exactly at the property line.** You cannot enter your neighbour’s land to cut roots in their soil. The cut must be made directly above the cadastral boundary. Any excavation on the neighbouring plot constitutes a trespass.
- **Do not compromise the tree’s stability.** If cutting the roots causes the tree to decline or fall, the tree’s owner can hold you liable for fault. Case law requires a reasonable cut that does not harm the tree’s survival.

In practice, this right to cut is not enough once the roots have already caused material damage to the pipes. You then need to establish liability, repair the damaged pipework, and possibly take legal action to obtain compensation.

## Pipe damage: who is liable?

When roots have damaged your pipes (breakage, cracking, deformation, recurring blockages), liability depends on the condition of the pipe at the time the roots penetrated it. Case law distinguishes between two situations.

### Pipes that met current standards

If your pipes were in good condition, correctly installed and compliant with applicable technical standards (DTU 60.33 for sanitation), root penetration constitutes an abnormal neighbourhood disturbance. The tree’s owner is then liable, even without fault, and must compensate the damage suffered: cost of the camera inspection, drain-clearing fees, and repair or replacement of the damaged pipes. [Article 1240](https://www.legifrance.gouv.fr/codes/article_lc/LEGIARTI000032041571) of the Civil Code (formerly Article 1382) is the legal basis for this liability.

### Ageing or poorly jointed pipes

If the roots entered through faulty joints, pre-existing cracks or non-compliant materials (degraded asbestos-cement, non-watertight cast iron, cracked stoneware), the tree’s owner can argue there is no causal link. The roots merely exploited an existing flaw. In that case, each party bears its own costs: you pay for the pipe repair, the neighbour owes no compensation, but you retain your right to cut the roots at the property line.

Hence the absolute necessity of an independent technical diagnosis before any liability claim.

## Diagnosis by camera inspection of the pipes

Running a camera inspection through the pipes establishes three elements that are decisive for the rest of the process:

- **The exact location of the roots.** The camera identifies the blocked sections, the depth of penetration, and the distance from the property line.
- **The condition of the pipe.** The report must state whether the pipe complied with DTU 60.33 sanitation standards at the time of penetration: slope, diameter, joint tightness, suitable material.
- **The origin of the penetration.** Did the roots enter through a faulty joint, a crack, a poorly sealed connection, or did they pierce a sound pipe?

This diagnosis is carried out by a plumber or a sanitation professional. The video report must be timestamped, annotated, and include captioned screenshots. This technical document will determine whether your compensation claim is admissible.

## Amicable procedure: formal notice to the tree owner

Before any legal action, a formal notice is mandatory. It proves that you attempted to settle the dispute amicably, a condition often required by the judge when awarding costs.

### Content of the formal notice

The registered letter with acknowledgement of receipt must include:

- A summary of the facts: recurring blockages, findings of root penetration, location of the tree.
- The camera inspection report as an attachment, with video captures and a technical conclusion on the pipe’s condition.
- Itemised quotes for repairing or replacing the damaged pipe.
- A request to cut the roots at the property line, in accordance with Article 673 of the Civil Code.
- A claim for compensation for costs already incurred: diagnosis, previous drain clearing, additional maintenance costs.
- A reasonable deadline to respond and act: two weeks to one month depending on urgency.

### The neighbour’s response and negotiation

If the neighbour disputes liability, they can request a counter-expert opinion or propose an amicable cost-sharing arrangement. If both parties agree on a split (for example: the neighbour cuts the roots at their own expense, you repair the pipe at yours), a signed written agreement avoids any later dispute. If the neighbour refuses or does not respond, an interim or full court action becomes necessary.

## Legal action: interim relief or full proceedings

### Interim relief for urgent measures

If the roots cause imminent damage or a clearly unlawful disturbance (a pipe about to fail, sewage backing up into the home), you can apply to the summary proceedings judge (juge des référés) of the competent Judicial Court. For Antibes, Cannes, Grasse and Vallauris, this is the Judicial Court of Grasse. For Nice and the eastern Alpes-Maritimes, it is the Judicial Court of Nice.

The summary proceedings judge can order:

- The cutting of the roots at the property line, with a daily penalty if the neighbour refuses.
- A court-ordered expert assessment if the parties dispute the origin of the damage.
- A temporary ban on any further backups, along with protective measures (pumping, emergency works).

Interim relief does not rule on final liability but allows you to obtain prompt provisional measures.

### Full proceedings for complete compensation

To obtain full compensation for the damage (cost of works, loss of use, distress if sewage backed up), you must sue the neighbour on the merits before the Judicial Court. The summons must include:

- The legal basis: Article 673 of the Civil Code, Article 1240 of the Civil Code (liability for abnormal neighbourhood disturbance).
- Supporting evidence: the camera report, quotes, drain-clearing invoices, photos of the root network if accessible.
- The itemised amount of damages, broken down: diagnosis, previous drain clearing, repairs, loss of use if the home was temporarily uninhabitable.
- A request for enforcement under penalty if the neighbour refuses to cut the roots after being ordered to do so.

The length of proceedings varies, from six to eighteen months depending on the court’s caseload and the complexity of the case.

## Special cases: protected or listed trees

Some trees are subject to regulatory or heritage protection (local urban plan, classified woodland, remarkable trees). In that case, cutting the roots may be prohibited or subject to authorisation from the town hall. You must then adapt your approach: repair the pipe without cutting the roots, share the costs with the neighbour, or apply for a justified exemption from the local authority.

If the exemption is refused, the judge can order the pipe repair to be split between the parties, or require the neighbour to pay compensation if the protected tree causes an abnormal neighbourhood disturbance.

## The role of the independent building expert

An independent building expert can step in at two stages of the process:

- **Before any legal action.** The expert reviews the camera report, checks the pipe’s compliance with DTU 60.33, identifies the tree species, estimates the cost of the work, and drafts a preliminary technical report usable during the amicable phase.
- **During proceedings.** If the judge orders a court expert assessment, the appointed expert maps the root network, verifies the property line, establishes the timeline of the damage, and proposes how liability should be apportioned.

Independent expertise allows you to negotiate on solid technical grounds, prepare an admissible claim, or challenge an incomplete court-ordered expert report.

## Common practical questions

### Can I cut the roots without notifying my neighbour?

Legally, yes – Article 673 of the Civil Code entitles you to do so. In practice, however, it is advisable to notify the neighbour in writing: this avoids hostile reactions, makes it easier to negotiate repair costs later, and serves as proof of good faith should the dispute end up in court.

### Can my neighbour stop me from cutting the roots?

No. Article 673 of the Civil Code is a matter of public policy: the neighbour cannot override it through a contractual clause, a verbal agreement, or a formal notice. They can, however, ask you not to compromise the tree’s stability, and hold you liable if the cut causes the tree to fall or die.

### What if the roots grow back after cutting?

Cutting the roots at the property line does not permanently solve the problem if the tree is vigorous. Two complementary solutions: install a root barrier along the property line (waterproof geotextile membrane, buried rigid panels), or replace the damaged pipe with a watertight PVC system with lip-seal joints, compliant with DTU 60.33 and less vulnerable to future root penetration.
