A dispute with the neighbours: noise, trees, boundaries

Neighbour disputes are the most common civil matters there are, and the cheapest to resolve badly. Two things decide how they go: whether you can describe the problem factually, and whether you use the conciliation route before the positions harden.

The standard is not "annoying"

Belgian law does not require neighbours to be silent, invisible or convenient. What it protects against is a nuisance that goes beyond the ordinary inconveniences of living side by side — measured against what is normal for that place, at that time of day, in that kind of neighbourhood. A workshop in an industrial street and the same workshop in a residential cul-de-sac are judged differently, and correctly so.

That is why a diary matters more than an adjective. Dates, times, duration, and what was happening. A few weeks of that is worth more than a page of complaint.

The recurring three

Noise, which is about frequency and hour rather than volume alone. Trees and hedges, where the rules on planting distances and overhanging branches are specific and old, and where the remedy is often a trim rather than a felling. And boundaries, which are a factual question first: a surveyor establishing where the line actually runs resolves a large share of these before any legal argument begins.

Building works and permits are a separate track: a complaint about a permit goes to the administration and its appeal procedure, not to a civil court.

Start with conciliation

The justice of the peace hears neighbour disputes and offers a free conciliation hearing. Both parties are invited, nobody is obliged to attend, and no judgment follows unless an agreement is reached and recorded. It is quick, it costs nothing, and it works more often than people expect — partly because it is the first time the two sides have had to state the problem in front of someone neutral.

When to involve a lawyer

For a single letter, often not. For a recurring nuisance, a boundary in genuine doubt, or a neighbour who has already instructed someone, take the diary, the photographs, the title deeds and any correspondence to a practice that does property work, and ask what a realistic outcome looks like before you ask what it costs.

This page is general information about how these matters usually work in Belgium. It is not legal advice about your own case, and only a lawyer who has read your documents can give you that.
