Verbal lease in Belgium: evidence and consequences
How to prove a verbal lease in Belgium, legal and tax consequences, and how to regularise an oral lease. Companion to the verbal lease validity guide.
How to prove the existence of an oral lease
In the absence of writing, the burden of proof falls on the person invoking the lease. Here are the elements accepted by the Belgian Justice of the Peace, ranked by probative value:
| Evidence | Strength | Example |
|---|---|---|
| Regular bank transfers | Strong | Monthly payments with “rent” mention |
| Written correspondence | Strong | Emails/SMS mentioning the rental |
| Municipal address registration | Strong | Residence certificate at the address |
| Utility bills | Medium | Water, gas, electricity in the tenant’s name |
| Testimonies | Subsidiary | Neighbours, family, colleagues |
| Photos/videos | Subsidiary | Presence of personal belongings |
The judge has sole discretion in assessing each element. A body of concordant evidence is generally sufficient: regular transfers + address registration + bills at the address constitute quasi-irrefutable proof.
For the basic principles of the oral lease in Belgium, consult our dedicated guide.
If you are in an oral lease, systematically keep all documents proving the existence of the rental relationship: bank statements, messages, bills. In case of dispute, this evidence will be decisive.
Legal consequences of an oral lease
Duration
The oral lease is automatically a 9-year (3-6-9) lease. The tenant benefits from all statutory protections: 3-month notice (2 in Brussels), termination compensation, tacit renewal.
Registration
Registration is impossible without a written document. Consequence: the oral lease is not enforceable against a buyer in case of sale of the property. This is the main risk.
Lease conditions
Without writing, the conditions (rent, charges, clauses) are those agreed orally. In case of dispute, the judge determines the conditions based on available evidence (transfer amounts = rent amount).
Taxation
The landlord must declare rental income in their tax return, whether the lease is written or not. The FPS Finance can cross-reference address registration data with the return to detect undeclared income.
Regularising an oral lease
Step 1: Agreement of the parties
Both parties agree to put the lease in writing. Neither the landlord nor the tenant can be forced to sign a written lease, but both have an interest in doing so.
Step 2: Drafting the lease
The written lease restates the existing conditions:
- Current rent (corresponding to transfers)
- Start date of occupation (move-in date)
- Duration: 9 years from the start date
- Standard clauses (insurance, deposit, property inventory)
Step 3: Registration
The written lease is registered with the FPS Finance within 2 months. Registration is free for primary residence leases.
Step 4: Property inventory
A property inventory can be drawn up at any time, even during the lease. It protects both parties in case of dispute on departure.
