Act fast and in writing. Send a reminder, then a formal notice by registered letter, then, if payment does not follow, apply to the justice de paix (peace court), which can order payment or end the lease. The two-month deposit (Wallonia, since 1 June 2023) covers only part of the arrears, so early action matters.
Unpaid rent is the risk every landlord fears, and in Wallonia the response is a defined escalation. The moment a payment is late, send a friendly written reminder. If it is ignored, follow with a formal notice (mise en demeure) by registered letter, setting a clear deadline and stating that legal steps will follow. Prompt, documented action protects your position.
If the arrears persist, the dispute goes to the justice de paix, the local peace court that handles residential lease matters in Belgium. The judge can order the tenant to pay, validate an end to the lease, and in the last resort authorise eviction. The court often begins with a free conciliation attempt, which can resolve matters faster and more cheaply than a full hearing.
The rental deposit is your first cushion but a limited one. In Wallonia the deposit is capped at two months of rent (in force since 1 June 2023, Droits Quotidiens), so it will not cover a long run of arrears plus any damage. That cap is precisely why speed matters: waiting three or four months before acting lets the debt outgrow the security.
The counter-intuitive lesson is that prevention beats cure. Careful tenant screening at the outset, a clear entry inventory of fixtures, and, where appropriate, rent-guarantee insurance do more to protect income than any court action after the fact. A landlord who reacts on day one of non-payment, rather than day sixty, almost always limits the loss, and a management partner can run this process for you.
