In Belgium

An exclusive mandate (mandat exclusif) is a contract giving a single estate agent the exclusive right to sell or rent a property for a defined period. In Belgium, the agent must be registered with the IPI (Institute of Estate Agents).

Advantages. The agent invests more effort (professional photos, virtual tours, premium listings) knowing their commission is guaranteed. A single point of contact simplifies communication for the owner.

Disadvantages. The owner cannot market the property themselves or through another agent during the mandate period. If the agent underperforms, the owner is locked in until expiry.

How it works

Duration. Typically 3 to 6 months, renewable. Belgian consumer protection rules require the mandate to have a defined end date.

Commission. For sales: typically 3% of the sale price (+ VAT). For rentals: typically 1 month’s rent (+ VAT).

Termination. The owner can terminate at expiry by not renewing. Early termination may incur a compensation fee as defined in the contract.

Good to know
An exclusive mandate must be in writing and clearly state its duration. In Belgium, a mandate agreed outside the agent’s office (e.g. at your home) benefits from a 14-day cooling-off period under consumer protection law.

Practical example

Christine wants to sell her apartment in Antwerp. She signs an exclusive mandate with an IPI-registered agent for 4 months. The agent produces professional photos, a virtual tour and lists on all major platforms. The apartment sells within 6 weeks at 95% of the asking price. Commission: 3% of 285,000 EUR = 8,550 EUR + VAT.
