Creating a lease online is fully legal in Belgium
You can create a legally compliant lease online in Belgium in about 15 minutes. Online platforms like BailBelgique generate documents that include all mandatory clauses required by regional legislation. The resulting lease has the same legal value as a paper document drafted by a notary or estate agent.
Belgian law does not require a lease to be drafted by a professional. Any private agreement between landlord and tenant is valid, provided it contains the legally mandatory clauses specific to each region. Online lease creation tools ensure compliance by guiding users through a structured form.
The key advantage of creating a lease online is the reduction of errors and omissions. Regional housing legislation has become increasingly complex, with mandatory annexes (EPC, fire safety, soil certificates) varying by region. An online tool keeps these requirements up to date.
A written lease is mandatory for residential tenancies in Belgium, so using an online platform is an efficient way to fulfil this obligation.
Step-by-step guide to creating a lease online
- Choose the lease type: primary residence, student housing, shared housing, or commercial
- Enter the parties’ details: name, address, national register number
- Describe the property: address, type, surface area, EPC rating
- Set the financial terms: monthly rent, charges (flat-rate or actual), rental deposit amount
- Add specific clauses: pet policy, smoking, permitted works, garden maintenance
- Review and sign: electronically via itsme or eID, or print and sign manually
- Register: submit to MyRent for registration
BailBelgique includes all region-specific mandatory clauses automatically. You can add a shared housing agreement, generate the inventory of fixtures, and register the lease — all from a single platform.
What must be included in a Belgian lease
Every lease in Belgium must contain certain mandatory elements:
| Element | Details |
|---|---|
| Identity of the parties | Full name, address, national register number |
| Property description | Address, type, surface area, must mention surface area |
| Rent and charges | Amount, payment method, charge calculation |
| Duration | Start date, end date, lease type |
| Rental deposit | Amount, type of account, deposit rules |
| EPC certificate | Mandatory annex in all regions |
| Regional annexes | Vary by region (fire safety, soil certificate, etc.) |
An incomplete lease may be challenged in court and certain clauses may be deemed unwritten. Always ensure your lease includes all mandatory regional annexes. Using an online lease creation tool significantly reduces the risk of omissions.
