Short answer: In Belgium your deposit is normally held on a blocked account in your own name — your landlord cannot simply keep it. It is released only when both of you sign the release, or when a judge (the Justice of the Peace) decides. There is no fixed legal deadline, but stalling well beyond about a month after you return the keys is considered unreasonable. If your landlord refuses, you escalate — for free — to the Justice of the Peace.
Where your deposit actually is
In most Belgian leases the security deposit (huurwaarborg / garantie locative) is not the landlord's money to spend. It sits on a blocked bank account opened in the tenant's name, and the interest belongs to you. The landlord cannot withdraw from it on their own — not at the start, and not at the end. (The maximum deposit is capped and depends on your region: typically 2 months' rent in Brussels and Wallonia on a blocked account, and up to 3 months in Flanders or where a bank guarantee is used — check your region's current rule.)
This matters, because it means a landlord "keeping" your deposit almost always requires your signature or a court order — they cannot legally just take it.
How the deposit is released
At the end of the lease the deposit is unblocked in one of two ways:
- You both sign a release form agreeing how much each side gets. The bank then pays out — usually within a couple of weeks.
- A judge decides. If you cannot agree, the Justice of the Peace (vrederechter / juge de paix) rules on it.
Belgian law does not set an exact deadline for return, but a delay much beyond ~30 days after you hand back the keys is generally treated as unreasonable. A landlord who simply goes quiet is not on solid ground. In Brussels, for leases entered into or renewed since 1 November 2024, the landlord must return the deposit within two months of the end of the lease — or owe 10% of the monthly rent for each month of delay.
What your landlord can — and cannot — deduct
A landlord may only hold back money for specific, justified reasons:
- Allowed: unpaid rent or charges, and damage beyond normal wear and tear, supported by the move-in vs move-out inventory.
- Not allowed: normal wear (faded paint, minor scuffs), pre-existing issues already noted at move-in, or routine maintenance.
The decisive document is the inventory of fixtures (plaatsbeschrijving / état des lieux) — the joint report, ideally with photos, made at move-in (within the first month) and again at move-out. Without a move-in inventory, it is very hard for a landlord to prove that any damage is new. This is why your photos and reports are worth more than any argument.
What to do if your landlord will not return it
- Ask in writing. Send a dated message (a registered letter carries the most weight) requesting the signed release and, if they are withholding anything, a written justification with amounts.
- Compare the inventories. If they claim damage, line the move-out report up against the move-in one. Anything not documented as new is normal wear.
- Escalate — it is free. If they still refuse, take it to the Justice of the Peace of the property's district. Conciliation there is free and often resolves it without a full case. Regional housing services and a tenants' union (huurdersbond / syndicat des locataires) can help you prepare.
Frequently asked questions
Can my landlord keep my deposit without my agreement in Belgium?
Generally no. The deposit is usually on a blocked account in your name and can only be released with both parties' signatures or by a Justice of the Peace decision. A landlord cannot unilaterally take it.
How long does a landlord have to return the deposit?
Belgian law sets no exact deadline, but a delay well beyond about 30 days after you return the keys is considered unreasonable. Release happens once you both sign or a judge decides.
What can a landlord deduct from the deposit?
Only justified amounts: unpaid rent or charges and damage beyond normal wear and tear, evidenced by the move-in vs move-out inventory. Normal wear and pre-existing issues cannot be deducted.
My landlord never did a move-in inventory — can they still deduct for damage?
It is very difficult for them to. Without a move-in inventory (plaatsbeschrijving) to compare against, a landlord usually cannot prove that damage is new rather than pre-existing.
What if my landlord simply refuses to sign the release?
Ask in writing, then take it to the Justice of the Peace of the property's district — conciliation is free. Tenants' unions and regional housing services can help you prepare your file.
Keep the evidence that wins this in one place
Deposit disputes are won on documentation — the dated inventory, the photos, the written requests. ImmoDesk keeps a tenant's lease, inventory, photos and messages with the landlord in one shared, timestamped place, and the deposit release becomes something you and your landlord settle together rather than argue over. Renting from a landlord who isn't on ImmoDesk yet? Create your free tenant account and invite them, so everything about your rental — including the deposit — lives in one record.
