Neighbor Refuses to Pay for Shared Wall Repairs in Marseille — Legal Remedies (Art. 655 Civil Code)

PROPERTY LAW — PARTY WALLS

Your shared wall is cracking, or leaning dangerously, but your neighbor in Marseille flatly refuses to contribute to the repair costs. You own a building in Le Panier or a villa in Les Goudes. Article 655 of the French Civil Code requires costs to be split 50/50. But when the other party stonewalls, you need a methodical approach. Here is exactly how to proceed, from formal notice through to enforced execution.

1. The legal framework: Article 655 of the Civil Code

The law is clear: repair and rebuilding of a shared (party) wall are the responsibility of everyone entitled to it, in proportion to their share of ownership. That means 50% for each owner in the case of full party-wall ownership (Art. 655 Civil Code; Cass. 3e civ., 24 Jan. 2007, no. 06-10.350).

What the law doesn’t cover: what to do when one party refuses. The solution goes through the courts, but intermediate steps can often avoid a trial altogether.

2. The preliminary survey (a key step)

Before taking any action, have the wall surveyed by an independent building expert — not your neighbor’s. The surveyor will assess:

• The cause of the damage (deterioration, construction defect, abnormal neighborhood disturbance…)
• The cost of the necessary work (repair or rebuilding)
• The urgency and any safety risks

Cost of a survey in Marseille: budget €800 to €1,500 for a standard party wall. This surveyor can be jointly appointed by agreement or designated by a judge in summary proceedings.

3. Formal notice via bailiff (huissier)

A registered letter isn’t always enough. To apply real pressure, have a bailiff’s notice (exploit) served on your neighbor. Cost: around €120. This notice:

• Officially records the request
• Sets a deadline (typically 30 days) to respond
• States the threat of legal action with a request for a daily penalty (astreinte)

4. Legal action before the Marseille Judicial Court

If the neighbor keeps refusing, take the case to the Marseille Judicial Court (tribunal judiciaire). The procedure runs as follows:

• Filing by summons: a lawyer is mandatory. Legal fees for this type of dispute run €1,500 to €3,000.
• Case management hearing: within 2 to 4 months. The judge may order a court-appointed expert survey (cost: €2,000 to €5,000, advanced by the claimant).
• Judgment: if the expert confirms the work is necessary, the judge will order the neighbor to pay their share (50%), backed by a daily penalty of €50 to €200 for late payment.
• Enforcement: if the neighbor still doesn’t pay, you can have the judgment enforced by a bailiff. The neighbor can be compelled to sell the property to pay the debt.

5. What if it’s urgent? (summary proceedings)

If the wall is at risk of collapsing, apply to the summary proceedings judge (juge des référés) at the Marseille Judicial Court. No lawyer required, by simple request (fast-track procedure). Timeline: 8 to 15 days to obtain a court order authorizing emergency work at the uncooperative neighbor’s expense. We obtained such an order in 11 days for a cracked load-bearing wall threatening an 18th-century building.

6. Getting reimbursed for your advance payment

You can carry out the work yourself (to prevent a collapse) and seek reimbursement afterward:

• Article 656 of the Civil Code: if the neighbor refuses to contribute, you can advance the cost and sue them for payment.
• The reimbursement claim has a 5-year limitation period (Art. 2224 Civil Code).
• Keep every invoice and the survey report.

Case study: On a building on the Cours Julien in Marseille, the party wall collapsed over 4 meters after a storm. The neighbor, a shop owner, refused to pay their share. The survey estimated the work at €12,000. After formal notice, summary proceedings, and judgment, the neighbor was ordered to pay €6,000 plus 5% annual interest from the date of formal notice, plus costs (survey, legal fees, bailiff).
