FAQ — Lease and contract
Registration, signature, termination, shared housing, commercial lease — all answers about lease contracts in Belgium.
-
No, a verbal lease is legally valid but strongly discouraged. Without a written document, it is nearly impossible to prove the agreed terms. Furthermore, an unwritten lease cannot be registered.
-
Yes, every lease for a primary residence must be registered within 2 months. Registration is free for residential leases and can be done online via MyRent.
-
Yes, in accordance with the eIDAS regulation. It is accepted by registration offices and Belgian courts.
-
A 9-year lease renews tacitly for 3-year periods if no one gives notice. A short-term lease renews once, then converts into a 9-year lease.
-
Both options are possible. A single lease with a joint liability clause better protects the landlord. Separate leases give more autonomy but complicate management.
-
Yes, the tenant can terminate at each triennial period (3, 6 years) with 6 months’ notice. The landlord can only terminate under strict conditions.
-
Yes, if the lease is registered, it is enforceable against the buyer. An unregistered lease can be terminated by the new owner.
-
As many as there are parties, plus one for registration. In practice, at least 3. With electronic signature, a single file is sufficient.
-
No, but strongly recommended for the landlord. Without it, each flatmate is only responsible for their share of the rent.
-
Yes, a prohibition clause is legal. Without an explicit clause, the tenant may keep a pet provided it does not cause nuisance.
-
Yes legally, but it cannot be registered and it is very difficult to prove the conditions in case of a dispute.
-
No, the signed electronic document has the same value as paper. It can be archived digitally and submitted as is for registration.
-
Registering a commercial lease costs 0.2% of the cumulative rent and charges over the full duration of the lease, with a minimum of €50.
-
Yes, the lease is transferred to the deceased tenant's heirs. The heirs can choose to continue the lease or terminate it under the conditions provided.
-
Yes in Brussels (mandatory since 2018). In Wallonia and Flanders, it is recommended but not required by law.
-
Yes, the sale is always possible. If the lease is registered, the buyer must respect the lease. That is why registration protects the tenant.
-
Several platforms allow you to create a compliant lease online, including BailBelgique. You fill in a guided form, regional annexes are generated automatically, and you can sign electronically.
-
Yes, the qualified electronic signature (itsme®, eID) is accepted as evidence before the justice of the peace, just like a handwritten signature.
-
By registered letter or bailiff's writ, between the 18th and 15th month before expiry. The landlord has 3 months to respond.
-
By an addendum to the lease signed by all parties (landlord + old and new flatmates). The addendum modifies the signatories without creating a new lease.
-
No, a private lease is sufficient for residential leases. A notarised lease is more common for commercial or emphyteutic leases but is not mandatory.
-
Yes, in Flanders the lease must be drafted in Dutch. A lease in French is not void but can be challenged before the court.
-
Yes, the intended use (primary residence, mixed use, professional) must be clearly stated. It determines the applicable legal regime.
-
Registration is free. Drafting can be done by yourself (free) or via an online service like BailBelgique (from €24.99) which generates a compliant lease with annexes.
-
Via a signature verifier (e.g. the EU's DSS). The certificate embedded in the PDF shows the signer, the date and whether the document was modified after signing.
-
No, the commercial lease law only applies to tradespeople and artisans in direct contact with the public. Liberal professions fall under general contract law.
-
In Flanders and Brussels, the pop-up lease has its own regime (max 1 year, renewable). In Wallonia, there is no specific framework — general contract law applies.
-
It is not mandatory but strongly recommended. The flatmate agreement regulates communal living (cleaning, noise, shared spaces) while the lease governs the relationship with the landlord.
-
The concept of a "trial period" does not legally exist in Belgian rental law. The tenant can terminate at any time with 3 months' notice, from the very first day.
-
The health index of the month preceding the lease anniversary is used. If the lease was signed on 15 March, the anniversary is 15 March each year, and the February index is used.
-
Registration is not mandatory but strongly recommended for the tenant. An unregistered lease is not enforceable against third parties, particularly in case of sale.
-
Yes. The European eIDAS regulation recognises three levels of electronic signature. The qualified signature (itsme®, Belgian eID) has the same value as a handwritten signature.
-
The tenant gives notice by bailiff's writ or registered letter, at least 6 months before the end of a triennial period. The landlord can only terminate under very strict conditions provided by law.
-
With a single lease: the flatmate gives notice under normal rules but remains jointly liable unless an addendum is signed. With separate leases: each person terminates their own independently.
-
The lease must be registered within 2 months of signing. Via MyRent, processing generally takes a few business days.
-
Yes, the tenant is entitled to 3 renewals of 9 years, provided the request procedure is followed (between 18 and 15 months before expiry).
-
Yes, several tenants can co-sign a commercial lease. As with residential shared housing, a joint liability clause is recommended.
-
Yes, but it is not in their interest. Without a signed inventory, the tenant is presumed to have received the property in good condition and will have to prove otherwise in case of a dispute.
-
The lease continues with the heirs. They have the same termination rights as the deceased landlord, including personal occupation.
