Rental deposit in Belgium: the 3 options explained

The rental deposit: protection for both parties

The rental deposit is an amount that the tenant constitutes at the start of the lease to cover potential damage or unpaid rent. In Belgium, three legal options coexist, each with its own rules for constitution and release.

The legal framework is regionalised: Brussels, Wallonia and Flanders each set the maximum amounts and procedures. One common point: the landlord can never receive the deposit into their own account. This prohibition protects the tenant in the event of the landlord’s bankruptcy or bad faith.

Understanding the three options allows the landlord to guide their tenant towards the most suitable solution, and the tenant to know their rights. To draft a compliant lease including the deposit clause, see our lease agreement templates.

Option 1: the individualised blocked account

This is the most common option. The tenant deposits the guarantee into a blocked bank account in their name. Interest is capitalised in their favour.

How it works

1. The tenant opens a rental deposit account at the bank of their choice
2. They pay the agreed amount in a single payment
3. The bank issues a certificate of constitution
4. The tenant hands the certificate to the landlord

Maximum amounts

Advantages and disadvantages

Advantage: simplicity, interest for the tenant, no additional cost.

Disadvantage: the tenant must have the full amount available at the time of constitution. For a rent of 900 EUR, this represents 1,800 EUR in Brussels or 2,700 EUR in Flanders.

Option 2: the progressive bank guarantee

This option allows a tenant who does not have the full amount to constitute the deposit progressively, through instalments spread over the duration of the lease.

How it works

The bank guarantees the landlord an amount equivalent to 3 months’ rent maximum in all three regions. The tenant repays this guarantee in instalments, generally deducted automatically from their account.

Conditions

• The tenant must hold a current account at the bank granting the guarantee
• The bank cannot refuse on the grounds of the tenant’s financial situation (legal obligation)
• Instalments are spread over a maximum of 3 years

Cost

Some banks charge administration fees (30 to 80 EUR) or interest on the guarantee. Compare offers before committing.

Option 3: the CPAS/OCMW guarantee

The CPAS/OCMW (Public Centre for Social Welfare) can stand as guarantor for people in financial difficulty. This option is reserved for low-income households.

How it works

1. The tenant submits a request to the CPAS/OCMW of their municipality
2. The CPAS/OCMW assesses the applicant’s financial situation
3. If the request is accepted, the CPAS/OCMW constitutes the deposit with a financial institution
4. The tenant then repays the CPAS/OCMW, often without interest

Access conditions

Criteria vary by CPAS/OCMW, but the general conditions include:

• Income below the threshold set by the CPAS/OCMW (often close to the integration income)
• Insufficient savings to constitute the deposit alone
• Lease compliant with regional legislation

Must the landlord accept?

Yes. The landlord cannot refuse a tenant solely because their deposit is constituted via the CPAS/OCMW. Such a refusal constitutes discrimination prohibited by the law of 10 May 2007.

Comparison of the three options and release

Release procedure

At the end of the lease, the deposit is released according to one of the following procedures:

1. Amicable agreement: both parties sign a release document. The bank unblocks the funds within 5 to 15 working days.
2. Partial disagreement: the parties agree on a partial release (e.g.: 500 EUR retention for damage). The balance is released immediately, the dispute concerns the difference.
3. Full dispute: in the absence of agreement, the justice of the peace must be referred to. The deposit remains blocked until the court decision.

Choosing the right option

The choice of rental deposit option depends essentially on the tenant’s financial capacity. As a landlord, you cannot impose one option over another, but you can inform your prospective tenants of the available options.

Key points to remember:

1. The blocked account is the simplest and most common option
2. The bank guarantee is a tenant’s right that the bank cannot refuse
3. The CPAS/OCMW intervenes for people in financial difficulty — refusing it is illegal
4. Cash is prohibited in all three Belgian regions
5. Release is by amicable agreement or justice of the peace decision
