Belgium Property Disputes: Neighbour Nuisance and Co-ownership

Disputes over property in Belgium mostly play out between private parties and are civil, not criminal, matters. This section, part of the wider Belgian legal guide, covers the two that generate the most questions: friction between neighbours over noise and other disturbances, and the rules that govern life inside a shared apartment building.

Both topics were recodified into the new Burgerlijk Wetboek, the Code civil, with effect from 1 September 2021, and both are heard, when they reach a courtroom, by the same accessible local judge: the vrederechter, the juge de paix. This page orients you first; the two spoke pages below go into the detail.

Two civil tracks, one local judge

What ties this section together is the forum. Whether the dispute is with the neighbour next door or with the other owners in your building, the competent court is the vrederechter, the juge de paix, and it is competent regardless of the amount at stake (Judicial Code article 591). That makes these among the most accessible disputes in the Belgian system: there is no threshold amount to clear and no need to start at a higher court.

The two spokes then diverge. Neighbour nuisance is about the relationship between two separate properties. Co-ownership is about the shared ownership of one building, with its own association, manager and voting rules.

Neighbour noise and nuisance

Since 1 September 2021, article 3.101 of the Civil Code sets a no-fault rule: a neighbour is liable where a disturbance exceeds the normal inconveniences of the neighbourhood and is attributable to them. The judge weighs factors such as timing, frequency, intensity and who was there first, and can order compensation, reimbursement of mitigation costs, or an order to stop the disturbance.

Night noise, nachtlawaai or tapage nocturne, is a separate, municipal question, handled through a GAS / SAC fine and the police, and the two routes can be pursued at the same time. The neighbour noise and nuisance page sets out the test, the remedies and the separate night-noise track in full.

Co-ownership and the syndic

Living in a shared apartment building means belonging to an association of co-owners, the vereniging van mede-eigenaars, the association des copropriétaires, with legal personality of its own. A syndic, a syndicus, manages the building on a mandate capped at three years, and the general assembly takes the important decisions by a graduated majority ladder that runs from an absolute majority, through two-thirds and four-fifths, up to unanimity to change the ownership shares. The co-ownership and the syndic page explains the association, the base deed, the majorities and how to challenge an unlawful assembly decision.

The two spokes

Neighbour noise and nuisance covers article 3.101, the no-fault nuisance test, the three remedies, the role of the vrederechter, the juge de paix, and the separate municipal night-noise track.

Co-ownership and the syndic covers articles 3.84 to 3.100, the association of co-owners, the syndic, the general assembly majorities, the supervisory council and the four-month action to annul an unlawful decision.

The following questions come up most often about Belgian property disputes.
