The Commercial Lease Act does not apply to liberal professions
The Commercial Lease Act of 30 April 1951 does not apply to liberal professions (doctors, lawyers, architects, accountants, etc.). These professionals use a standard civil lease (bail de droit commun). This means they do not benefit from commercial tenant protections such as the right to renewal or the 9-year minimum term.
The Commercial Lease Act applies specifically to leases for premises used for retail trade or craftmanship where there is direct contact with the public. Liberal professionals, by definition, do not engage in commercial trade — they provide intellectual or scientific services.
This distinction has significant practical consequences. Liberal professionals who lease premises do not benefit from:
- The 9-year minimum lease duration
- The right to 3 lease renewals
- The compensation framework for landlord-initiated termination
- Protection against property sale
Instead, the lease is governed by the Civil Code and any regional residential or general lease provisions that may apply.
What type of lease should liberal professionals use
| Profession | Applicable law | Lease type |
|---|---|---|
| Doctor, dentist | Civil Code | Standard civil lease |
| Lawyer, notary | Civil Code | Standard civil lease |
| Architect, engineer | Civil Code | Standard civil lease |
| Accountant, tax advisor | Civil Code | Standard civil lease |
| Pharmacist | Commercial Lease Act | Commercial lease (retail activity) |
| Optician with shop | Commercial Lease Act | Commercial lease (retail activity) |
Key features of a standard civil lease for professionals:
- Duration freely negotiated (no 9-year minimum)
- No automatic right to renewal
- Termination rules per contract terms
- No statutory compensation framework
- Registration optional but recommended
BailBelgique offers specific lease templates for liberal professions. These include protective clauses that compensate for the absence of the Commercial Lease Act’s tenant protections, such as longer notice periods and renewal options.
Exceptions and grey areas
The boundary between commercial and liberal activities is not always clear:
- A pharmacist sells products directly to the public and typically falls under the Commercial Lease Act
- An optician with a retail shop engages in commercial trade and may benefit from commercial lease protections
- A doctor with a publicly accessible clinic may argue for commercial lease treatment if client access is similar to retail
- A lawyer sharing office space in a commercial building remains under civil lease law
The key criteria Belgian courts examine are:
- Is there direct contact with the public in the premises?
- Does the activity involve commercial trade or craftmanship?
- Is the location essential for attracting clientele?
If you are a liberal professional, be careful about signing a “commercial lease” — the Commercial Lease Act’s restrictions (9-year term, triennium termination only) will apply even though the protections may not be available to you as a non-commercial tenant. Ensure the lease type matches your actual legal situation.
Regional specifics
Brussels-Capital Region
The distinction between commercial and liberal professions is federal law. Brussels courts have developed significant case law on borderline cases, particularly for medical practitioners and consultants with high-profile offices.
Wallonia
Walloon courts apply the same federal distinction. The rise of medical centres and multi-practitioner offices in Wallonia has created new questions about whether collective professional premises qualify for commercial lease protection.
Flanders
Flemish courts apply the same federal framework. Flanders has seen increased discussion about the status of veterinary clinics and dental practices with retail components (product sales), which may partially fall under commercial lease law.
