Creating a lease ranges from free to several hundred euros
You can create a lease for free by drafting it yourself, but you risk missing mandatory clauses. Online platforms like BailBelgique offer legally compliant lease creation at affordable prices. A notary or lawyer typically charges 300 to 600 EUR. Registration with the FPS Finance is free for residential leases (50 EUR for commercial leases).
Belgian law does not require a lease to be drafted by a professional. Any private agreement is valid as long as it contains the mandatory clauses required by regional legislation. However, the complexity of current housing laws — with region-specific annexes and mandatory mentions — makes professional assistance advisable.
The choice of creation method depends on your budget, legal knowledge, and the complexity of the rental situation. A written lease is mandatory for residential tenancies, so some cost is inevitable.
Cost comparison by creation method
| Method | Cost | Pros | Cons |
|---|---|---|---|
| Self-drafted | Free | No cost | High risk of missing clauses |
| Online template (generic) | Free to 30 EUR | Low cost | May not include regional annexes |
| Online platform (BailBelgique) | Varies | All clauses, e-signature, registration | Monthly or per-lease fee |
| Real estate agent | 150-400 EUR | Professional review | Not specialized in legal compliance |
| Notary | 300-600 EUR | Legal certainty | Expensive, slow process |
| Lawyer | 300-600 EUR | Custom clauses | Expensive, not always necessary |
The most important factor is not the cost but the completeness of the lease. A free but incomplete lease can lead to expensive disputes. Each region has specific mandatory annexes that must be included.
BailBelgique offers a complete lease creation experience: all mandatory clauses, regional annexes, electronic signature, and registration — all at a fraction of the cost of a notary.
Hidden costs to avoid
Beyond the lease creation itself, several additional costs should be considered:
| Cost | Amount | When |
|---|---|---|
| Lease registration | Free (residential) / 50 EUR (commercial) | Within 2 months of signing |
| EPC certificate | 150-300 EUR | Before advertising the property |
| Electrical inspection | 100-200 EUR | Required in Flanders |
| Inventory of fixtures | 150-500 EUR (if professional) | At lease start |
| Notarization | 300-600 EUR | Only if required |
None of these costs can legally be charged to the tenant (except the tenant’s share of the inventory of fixtures). The landlord bears the cost of lease creation, EPC, and registration.
Beware of free lease templates found online — many are outdated or do not comply with current regional legislation. Since 2018, all three regions have introduced new mandatory clauses and annexes. Using a notarized lease is not mandatory but can provide additional legal security.
Regional specifics
Brussels-Capital Region
Brussels requires specific mandatory annexes that increase the complexity (and potential cost) of lease creation. The Brussels Housing Code mandates a regional information annex and specific clauses on tenant protections.
Wallonia
Wallonia has its own set of required annexes under the Walloon Residential Lease Decree. The decree includes a mandatory explanatory guide that must be attached to every lease. Free templates are available from the Walloon region’s website.
Flanders
Flanders requires the most annexes (rights annex, EPC, electrical inspection report, flood zone information), making professional lease creation particularly valuable. The Flemish Housing Rental Decree lists all requirements.
Regional housing legislation defines mandatory clauses and annexes. Registration Duties Code governs registration fees. No federal law requires professional drafting of leases.
