How inaccurate property size listings impact rental agreements in Belgium

In the bustling real estate market, property listings serve as the primary source of information for potential tenants. These listings, whether for sale or rent, often highlight the property’s livable area, sometimes even detailing the space distribution among rooms. But what happens if there’s a discrepancy between the listed size and the actual size of the property? Can a tenant use this as a reason to claim the lease is invalid?

Is the lease null and void?

If a landlord advertises a property with an exaggerated size, a tenant might argue that they were misled during the lease’s conclusion, rendering the agreement null and void. However, in practice, this argument often doesn’t hold water, especially if the tenant had the opportunity to visit the property before signing the lease, which is typically the case. It’s reasonable to assume that during such a visit, the tenant could have noticed the property’s actual size, contrasting it with the advertised dimensions.

Terminating the lease

If a tenant decides to terminate the lease based on the size discrepancy (and the claim is deemed unjustified), it could lead to financial repercussions for the tenant. The landlord might argue that the tenant terminated the lease without a valid reason. In such a scenario, the tenant might owe the landlord compensation equivalent to the standard notice period and/or the legal termination fee applicable during the initial years of the lease.

Protecting both parties

For landlords: It’s crucial to ensure that property listings are accurate. Misrepresentations, even if unintentional, can lead to disputes and potential legal challenges. Using professional services or tools to measure the property can prevent such discrepancies.

For tenants: Always visit the property before signing the lease. This not only allows you to verify the property’s size but also helps in assessing other aspects like its condition, amenities, and neighborhood. If you have doubts about the listed size, consider using measurement tools or seeking expert advice.

Legal implications

While the Belgian legal system provides remedies for misrepresentations in property listings, it’s essential to approach such matters with caution. Both landlords and tenants should be aware of their rights and responsibilities. Consulting with legal professionals can offer clarity and guidance, ensuring that both parties are protected.


The real estate market thrives on trust and transparency. While discrepancies in property listings can lead to disputes, it’s essential for both landlords and tenants to approach such situations with understanding and diligence. By ensuring accurate listings, visiting properties before signing leases, and seeking legal advice when in doubt, both parties can enjoy a harmonious rental relationship.
