What is a notice period?
The notice period is the written notification that announces the end of a rental contract. Its duration varies depending on who is terminating, the type of lease, and the year of the contract. This guide details the applicable notice periods in 2026 and how to calculate them without error.
A notice period is a legal interval between the notification of the lease ending and the actual departure date. The rules apply to all types of rental contracts.
For the general rules on termination: termination hub.
Standard notice durations
| Type of termination | Notice |
|---|---|
| Tenant (9-year lease) | 3 months |
| Tenant (short-term lease) | 3 months |
| Tenant (student lease) | Variable (often 2 months) |
| Landlord (all grounds) | 6 months |
| Fixed-term contract | Specific clause in the lease |
The 3-month notice for the tenant and 6-month notice for the landlord is the standard for a 9-year primary residence lease.
Details for tenants: termination by tenant. Details for landlords: termination by landlord.
How to calculate your notice period
The notice period begins on the 1st day of the month following receipt of the registered letter. Not the date of posting, but the date of receipt.
Practical example: registered letter sent 12 March, received 15 March, 3-month notice begins 1 April, lease effectively ends 30 June.
Rent remains due throughout the notice period, even if the tenant leaves the property early. Keep the acknowledgement of receipt: it proves the notification date.
Fixed-term contracts: specific notice
For a fixed-term contract (student lease, lease with a set end date), the rules differ:
- Check the specific clause in the lease.
- Notice often shorter (1 to 2 months).
- Contractual compensation may apply.
- In the absence of a clause, the primary residence lease rules apply by default.
A student lease generally allows flexible termination. A short-term lease (3 years or less) has a 3-month notice period with reduced compensation (1.5 / 1 / 0.5 months depending on the year).
Notice and compensation: the connection
In the early years, a standard notice comes with compensation for a departing tenant.
| Year of lease | Compensation |
|---|---|
| 1st year | 3 months’ rent |
| 2nd year | 2 months’ rent |
| 3rd year | 1 month’s rent |
| 4th year onwards | None |
The amount is calculated on the indexed rent in force at the time of notice. On the landlord’s side, compensation (without grounds) amounts to 9 months’ rent (end of 1st triennium) or 6 months (end of 2nd triennium).
Who notifies whom?
The notification must go from one party to the other.
Tenant’s notice
Registered letter to the landlord (or their agency). Standard 3-month notice. No grounds needed for a primary residence lease.
Landlord’s notice
Registered letter to the tenant. 6-month notice. Legal grounds mandatory (personal occupation, works, or without grounds subject to compensation).
During the lease, the notice may also be replaced by a mutual agreement.
Notice for a furnished lease
A furnished lease follows the primary residence lease rules if the property is the tenant’s main residence. Standard 3-month notice, same compensation.
If the furnished property is rented short-term, the rules are more flexible.
Mandatory form of notice
Notice may only be given by:
- Registered letter with acknowledgement of receipt (standard).
- Electronic registered letter via eBox, bpost, Zendreq (same legal value).
- Bailiff’s writ (in case of refusal or dispute).
A text message, simple email, or verbal declaration does not suffice. Only the written registered form starts the notice period.
Common mistakes to avoid
- Wrong start date: calculate from receipt, not from posting.
- Missing mandatory details: identities, address, lease reference, grounds if landlord.
- Sending by email only: insufficient. Always back up with a registered letter.
- Notice too short: strictly respect 3 months (tenant) or 6 months (landlord).
- No acknowledgement of receipt: without proof, impossible to calculate correctly.
Termination by mutual agreement: no notice required
The notice period can be avoided if both parties sign a mutual agreement. This form of termination allows fixing a free end date, waiving compensation (if negotiated), and simplifying departure. The agreement must be written and signed by both parties.
