Resolving Disputes in Belgian Co-ownership: Justice of the Peace and Mediation

Disputes in co-ownership are among the most common forms of civil litigation in Belgium. Whether the conflict involves unpaid charges, a contested general assembly resolution, or a neighbour's noisy renovation, Belgian law provides specific mechanisms for resolution. For international owners unfamiliar with the Belgian judicial system, understanding these mechanisms is essential to protecting your rights.

Common Types of Co-ownership Disputes

Belgian co-ownership disputes typically fall into four categories:

Between co-owners: noise complaints, unauthorised modifications to private lots affecting common parts, encroachment on common areas, short-term rental disagreements.
Co-owner vs syndic: failure to execute GA resolutions, opaque financial management, neglected maintenance, refusal to convene a general assembly.
ACP vs defaulting co-owner: recovery of unpaid service charges, enforcement of internal rules, removal of unauthorised structures.
ACP vs third parties: claims against contractors for defective works, insurance disputes, disputes with utility providers.

Justice of the Peace: Exclusive Jurisdiction

Art. 577-12 Belgian Civil Code grants the justice of the peace (juge de paix / vrederechter) exclusive jurisdiction over all co-ownership disputes. This is a significant advantage: unlike ordinary civil courts, the justice of the peace has no upper limit on the value of claims in co-ownership matters.

The justice of the peace is a local judge, sitting in each judicial canton. The competent court is the one for the canton where the building is located. Key characteristics:

Speed: typical proceedings last 3 to 6 months, significantly faster than the civil court of first instance (often 12-24 months).
Lower costs: court fees are modest (€50-200 for a summons), and legal representation is not mandatory, though it is advisable for complex matters.
Conciliation role: the justice of the peace often attempts to mediate before issuing a judgment, which can lead to faster, mutually acceptable outcomes.
Provisional measures: the justice of the peace can order urgent provisional measures (e.g., suspending works, appointing a provisional syndic) pending a final decision.

Proceedings are initiated by a summons (citation / dagvaarding) served by a bailiff, or in some cases by a voluntary appearance (comparution volontaire).

Mediation as an Alternative

Before or during court proceedings, parties may opt for mediation. Belgium has a structured mediation framework:

Mediators must be accredited by the Federal Mediation Commission (Commission fédérale de médiation).
Sessions typically cost €150-300 per hour, shared between parties.
A mediated agreement, once approved (homologué) by the justice of the peace, has the force of a court judgment.

Mediation is particularly effective for disputes between co-owners or between the council of co-ownership and the syndic, where preserving an ongoing relationship matters. It is less suitable for arrears recovery, where a court judgment with enforcement powers is usually needed.

Challenging General Assembly Resolutions

Any co-owner who voted against a resolution, abstained, or was absent may challenge that resolution before the justice of the peace. Art. 577-9 §2 Belgian Civil Code sets strict conditions:

Deadline: the action must be filed within 4 months of the date the minutes were communicated (or the date the owner became aware, if absent).
Grounds: the three accepted grounds are:
1. Procedural defect: inadequate convocation (less than 15 days, missing agenda items), quorum not verified, minutes not signed.
2. Illegality: the resolution violates the Belgian Civil Code, the co-ownership regulations, or mandatory legislation.
3. Abuse of majority: the majority used its voting power to benefit itself at the expense of the minority, or the decision is manifestly unreasonable (e.g., refusing necessary repairs to keep charges artificially low).

If the justice of the peace annuls a resolution, the matter returns to the general assembly for a new vote. The court does not substitute its own decision for that of the GA.

The Formal Notice: A Prerequisite

Before initiating court proceedings, Belgian practice requires sending a formal notice (mise en demeure in French, ingebrekestelling in Dutch). This registered letter puts the other party on notice of the claim and demands compliance within a reasonable period (typically 15-30 days).

While not always a strict legal requirement, the formal notice serves three purposes: it demonstrates good faith to the court, it starts the clock on certain legal interest calculations, and it often resolves the dispute without litigation. Many co-ownership disputes — particularly unpaid charges — are settled after a well-drafted formal notice.
