Indefinite-term lease: is it possible in Belgium?
Can you conclude an indefinite-term lease in Belgium? Legal framework, consequences, differences with the 3-6-9 lease and alternatives for landlords and tenants.
Open-ended leases in Belgian law
In Belgium, the concept of an open-ended lease is limited to certain types of leases. For primary residence leases, the law imposes minimum durations that make an open-ended lease impossible.
The Belgian system distinguishes three regimes:
| Type of lease | Duration | Open-ended possible? |
|---|---|---|
| Primary residence | 3-6-9 years or short-term | No |
| Commercial | Minimum 9 years | No |
| Ordinary law (garage, office, secondary residence) | Free | Yes |
The ordinary law lease is the only one that can be concluded without a fixed duration. It is the residual regime of the Belgian Civil Code, applicable when no specific legislation applies.
Primary residence lease: never open-ended
The rule
Since the law of 20 February 1991 (and its regional amendments), every primary residence lease has a statutory duration:
- No duration mentioned — automatically 9 years
- Duration mentioned of 3 years or less — short-term lease
- Duration mentioned between 3 and 9 years — reclassified as 9-year lease
- Duration mentioned of 9 years or more — lease of the agreed duration
There is no possibility of concluding an open-ended primary residence lease in Belgium. Even an oral lease (legal but inadvisable) is automatically a 9-year lease.
This rule protects the tenant: they always know how long they are committed and when they can leave. The landlord is also protected because they know the possible termination deadlines.
Ordinary law lease: open-ended is possible
Scope
The ordinary law lease applies to:
- Garages and parking spaces (unless accessory to a residential lease)
- Offices without public contact
- Secondary residences
- Warehouses and storage premises
- Unbuilt land
Termination
In an open-ended ordinary law lease, each party may terminate at any time subject to a notice period:
| Duration of occupation | Minimum notice |
|---|---|
| Less than 1 year | 1 month |
| 1 to 3 years | 3 months |
| 3 to 6 years | 3 months |
| More than 6 years | 6 months |
Termination is effected by registered letter or bailiff’s writ. There is no termination compensation.
Which duration to choose for your lease?
For a primary residence
You have no choice: the lease is 9 years (or short-term if less than 3 years). Prefer the 9-year lease for stability, or the short-term lease if you anticipate recovering the property quickly.
For an ordinary law property
An open-ended lease offers flexibility but little security for either party. Prefer a fixed-term lease (3, 6 or 9 years) to avoid surprises.
In all cases, put the lease in writing and register it with the FPS Finance. To create a lease suited to your situation, use our online lease generator.
