Civil Liability of Landlord and Tenant in Belgium

A water leak flooding the downstairs neighbour's flat. A roof tile flying off and smashing the windscreen of a car parked outside the building. A fire starting in the living room and gutting the entire floor. In these moments, one question demands an answer: who pays? The answer depends on a distinction that many Belgians still confuse — the difference between the civil liability of the landlord and that of the tenant. In Belgium, property law allocates obligations between landlord and tenant in a precise, if not always intuitive, way. The Civil Code, the Act of 6 July 1989 on residential leases, and the regional decrees adopted following the regionalisation of the matter in 2014 (Flanders, Wallonia and the Brussels-Capital Region each have their own rules) paint a complex picture. The result: costly disputes, poorly chosen insurance policies and avoidable legal proceedings. This article untangles the respective liabilities of the landlord and the tenant, the compulsory or strongly recommended insurance policies, and the steps to take when a loss occurs. Whether you are a landlord or a tenant, understanding these rules could save you thousands of euros in unwelcome surprises.

Civil Liability of Landlord and Tenant in Belgium

Compulsory Insurance: Civil Liability for Landlords and Tenants

Here is a reality that surprises many tenants: in Belgium, fire insurance for tenants is not required by federal law in every case. In practice, however, it has become virtually indispensable for covering your civil liability.

Tenant liability insurance: compulsory in all three regions

Since the regional legislation of 2017 and 2018, a tenant of a residential property is legally required to take out insurance covering their rental liability.

In practice:

  • Wallonia (Decree of 15 March 2018): the tenant must be covered against fire risks for the duration of the lease
  • Brussels (Ordinance of 27 July 2017): the same obligation applies, with the possibility for the landlord to take out the insurance themselves and pass the cost on to the tenant in the rent if the tenant fails to do so
  • Flanders (Vlaams Woninghuurdecreet of 24 October 2018): the landlord may require proof of fire insurance

In practice, this cover costs between €80 and €200 per year depending on the size of the property, the insured value of the contents and the insurer. A small price to pay for protection against a loss that can run to several tens of thousands of euros.

The landlord's insurance: building owner liability

For landlords, no federal law formally requires property owner civil liability insurance. But going without building owner liability cover is playing with fire — both literally and figuratively.

This insurance covers your liability as an owner for damage caused by the building to third parties:

  • A tenant injured by a defective handrail
  • A neighbour suffering water damage originating from your building
  • A passer-by struck by an object falling from your façade

Average cost: between €150 and €400 per year for a standard flat, depending on the rebuilding value of the property.

Questions fréquentes

Is a tenant required to take out insurance in Belgium?

Yes, in all three Belgian regions (Wallonia, Brussels and Flanders), a tenant of a residential property is legally required to hold insurance covering their rental liability. In practice, this takes the form of fire insurance with tenant liability cover. The landlord may request proof of the policy, and in certain cases (Brussels in particular), the landlord may take out the insurance themselves and pass the cost on to the tenant in the rent.

Who pays in the event of water damage in a rented flat?

It depends on the source of the leak. If it originates from an ageing defective pipe or a construction fault, the landlord is liable. If it results from a tap left running or a seal that the tenant should have replaced, the tenant is liable. Where damage is caused to neighbours, the tenant's rental liability insurance or the landlord's property owner liability insurance will intervene depending on the circumstances.

Can the landlord retain the rental deposit to cover repairs without the tenant's agreement?

No. The landlord cannot unilaterally use the rental deposit to fund repairs. If the tenant contests the matter, the landlord must obtain either the tenant's consent or a decision from the Justice of the Peace. The deposit is held in a separate bank account and may only be released by agreement of both parties or by court order.

What is the landlord's liability for 'ruin of a building' under Article 1386 of the Civil Code?

Article 1386 of the Belgian Civil Code establishes strict liability for the owner of a building whose ruin — owing to lack of maintenance or a construction defect — causes damage. The owner is presumed liable without the victim having to prove fault. The owner can only escape liability by proving force majeure or the exclusive fault of a third party.

Within what time limit must I notify my insurer of a loss?

Under the Belgian Insurance Code (Act of 4 April 2014), you have 8 working days to report a fire, water damage or explosion. For theft, the deadline is 3 working days, with a police report required. For natural disasters, the deadline may be reduced to 5 days. These deadlines must be strictly observed — a delay can result in a reduction or refusal of compensation.

Are tenant repair obligations the same in all regions of Belgium?

No. Since the regionalisation of tenancy law in 2014, each region has adopted its own legislation. Wallonia (Decree of 15 March 2018), Brussels (Ordinance of 27 July 2017) and Flanders (Vlaams Woninghuurdecreet of 24 October 2018) each have specific rules on tenant repairs, maintenance obligations and insurance. The address of the rented property determines which regional legislation applies.

What should I do if my insurer refuses to compensate me after a loss?

Start by contacting your insurer's internal mediation service. If that fails, refer the matter to the Insurance Ombudsman (ombudsman.as) — a free procedure. At the same time, you can challenge the assessment by appointing an independent expert of your choice. If the dispute persists, you can bring a claim before the competent court (the Justice of the Peace for smaller amounts, the Court of First Instance for larger claims). Consult a specialist lawyer if the financial stakes are significant.

Is the tenant liable for an accidental fire that they did not negligently cause?

Under Article 1733 of the Civil Code, the tenant is presumed liable for fires occurring during the tenancy, even accidental ones — unless they prove that the fire originated on a neighbour's property or in the common parts, or that it was due to a construction defect. This is precisely why tenant liability insurance is essential: it covers this statutory liability.
