Where are the statutory rights and obligations in commercial leases to be found?

Commercial lease law in Belgium is spread across several legal sources, which often makes it unclear to tenants and landlords where exactly their rights and obligations are set out. This article gives a clear overview of commercial lease legislation in Belgium, including the relationship between the Commercial Lease Act, the Civil Code and case law.

A tenant or landlord who wants to take action must first know their rights. But where exactly are they to be found? Commercial lease legislation in Belgium is spread across various sources, so it is not always clear which rules apply and which provisions take precedence. This article brings clarity.

In this article you will discover, among other things:

  • where the general lease rules are found in the Civil Code;
  • exactly which provisions are found in the Commercial Lease Act of 1951;
  • what protection the commercial tenant receives through specific derogations from the general law of lease;
  • how case law supplements and clarifies commercial lease legislation; and
  • why these dispersed sources together form the complete framework for commercial leases.

Where are the rules on commercial leases to be found?

The rules on commercial leases are spread across three major legal pillars: the general lease regime, the specific Commercial Lease Act of 1951, and case law. Below is an overview in clear language.

The general lease regime

The basic rules for leasing immovable property are found in the Civil Code. These rules are called the general law of lease. They apply only insofar as they do not conflict with the specific provisions of the Commercial Lease Act.

At present these rules are still found in the Old Civil Code:

  • Art. 1708–1712: general provisions on lease
  • Art. 1714–1762bis: rules on the lease of immovable property

In future these provisions will move to the new Civil Code, more specifically Book 7 – Special contracts. The bill (document 56-746/001) can be consulted on the website of the Belgian Chamber of Representatives.

The specific commercial lease regime

The Commercial Lease Act of 30 April 1951 forms the heart of commercial lease legislation. This Act applies only to classic commercial premises: shops, hairdressing salons, hospitality businesses and other places to which customers have physical access.

What does the Commercial Lease Act regulate?

The Act contains rules on, among other things:

  • a minimum term of 9 years (art. 3);
  • the tenant’s right to carry out certain alterations (art. 7–9);
  • the right to transfer or sublet together with the business (art. 10–11);
  • protection upon sale of the premises (art. 12);
  • up to three lease renewals of 9 years each (art. 13–15 and 18–20);
  • restrictions on refusal by the landlord (art. 16, 21–24);
  • eviction compensation in certain cases (art. 25).

Why does this matter?

The Commercial Lease Act primarily protects the commercial tenant, so that they can:

  • build up a customer base;
  • recoup investments;
  • not be suddenly evicted from the premises.

The Act also creates certainty for the landlord: commercial premises usually remain let for a long time and retain their value.

A baker who sells their business may transfer their commercial lease to the new baker. Even if the agreement prohibits this, this right continues to apply under the Commercial Lease Act.

The role of case law

Not every situation is covered word for word in the Act. That is why case law plays an important role in interpreting commercial lease rules.

Courts rule on, among other things:

  • disputes about rent review;
  • conflicts over alteration work;
  • interpretation of the conditions for a commercial lease;
  • questions concerning transfer, subletting and eviction.

Case law has no formal legislative force, but it does provide guidance for applying the Commercial Lease Act in practice.

The contract

Although the lease contract is strictly speaking not a statutory source, it naturally does contain provisions on the specific arrangements between tenant and landlord. Importantly, these contractual rules may not deviate from the mandatory provisions of commercial lease legislation. A clause that conflicts with the law is in principle not valid.


Frequently asked questions (FAQ)

To which commercial activities does the Commercial Lease Act apply, and when does it not?

The Act applies where the premises mainly serve retail trade or a craft activity with customer contact. It does not apply to mere storage or office work. Our specialists can examine with you whether your activity falls under the Commercial Lease Act.

What if there is no written contract?

An oral commercial lease also falls under the Commercial Lease Act when the conditions are met.

Does commercial lease law also apply to pop-up shops?

Not always. For written contracts of less than one year, the Commercial Lease Act does not apply. Special legislation then applies.

What if the premises are partly residential and partly commercial?

Then the main use is decisive.

How can one prove that the Commercial Lease Act applies?

By all means of evidence: bank statements, e-mails, witnesses, invoices, etc.
