In short
Entrusting the sale of your property to an estate agency (agence immobilière / vastgoedmakelaar) requires a written contract, the brokerage (or intermediation) contract (contrat de courtage / bemiddelingsovereenkomst). A Royal Decree of 28 September 2023 sets the mandatory clauses when the client is a consumer. With exclusivity, the contract lasts 6 months maximum. Without exclusivity, it can be open-ended with a notice period of 2 months maximum. You have 14 calendar days to withdraw. The text below follows the summary published by the IPI (Professional Institute of Estate Agents), which refers to the Royal Decree itself as the reference text.
Exclusive or non-exclusive
- Non-exclusive: you can entrust your property to several agencies, or sell it yourself. The contract can be open-ended, provided the notice period is stated and does not exceed 2 months.
- Exclusive or co-exclusive: only this agency (or this group of agencies) can represent you. The IPI writes that “the term of the contract is a maximum of 6 months”.
A penalty clause can sanction a breach of exclusivity (for example if you sell through another channel). It cannot exceed 75% of the commission.
Tacit renewal
A fixed-term contract can be extended automatically. The clause must then:
- appear on the first page, in bold, in a separate box;
- state the last date for objecting to it, at the latest 1 month before the end of the contract.
Once extended, you can end it at any time, without compensation, with a notice period of at most 1 month if the initial term was 3 months or less, or at most 2 months if it was longer.
Terminating the contract
The contract must always allow you to terminate “without having to give a reason”. Any compensation is capped:
| Situation after termination | Compensation cap |
|---|---|
| Property not sold within 6 months, termination in the first 3 months | 50% of the commission |
| Property not sold within 6 months, later termination | 25% of the commission |
| Property sold within 6 months, by you or a third party | 75% of the commission |
| Same, if the buyer had received specific, individual information from the agent | up to 100% of the commission |
These caps are maximums set by the decree. The contract can provide for less. If the agency introduced candidates and a commission is due for a sale to one of them, it must give you their names “within 7 working days” after the end of the contract.
The 14-day right of withdrawal
You have 14 calendar days to withdraw, without giving reasons. A clause that removes this right is void. If the contract is concluded at a distance or off-premises, the agent must attach a model withdrawal form, which you are not obliged to use.
You can ask in writing for the agent to start work during this period. You then acknowledge, in a separate signed statement, that you lose the right to withdraw once the assignment has been fully performed. Only sign this statement if you are sure you want to start straight away.
Remuneration
The contract must state the agent’s commission as a total price: VAT included, with all other taxes and all mandatory service charges. So compare amounts including all taxes. The pages consulted do not set a percentage: the rate is a clause of the contract.
Other mandatory points:
- if the commission is due on receipt of a valid offer, that offer must be made on a durable medium;
- the contract must state that no fee or commission is charged if the sale fails because of a suspensive or resolutive condition;
- you are informed at least once a month, on a durable medium, of the progress of the assignment.
What the contract must describe
- the agent’s assignment and powers, under a single heading: can the agent sign on your behalf? which advertising channels will be used?
- the exact date and address of signing (commune, street, number), not a pre-printed mention;
- as an annex, the list of required certificates, such as the EPB certificate (PEB).

What it costs
The cost is the commission written in the contract, VAT included. It is a negotiable clause between you and the agency: ask for several offers, with the total amount including all taxes and the detail of the services included. To compare, add the costs you bear in any case (EPB certificate, electrical inspection). See also purchase costs for what the buyer will add to the price.
Which professional to consult
Before signing, you can check the estate agent with the IPI. A notary can review the brokerage contract and the sale agreement that will follow: see the sale agreement. For a clause that seems unfair to you, a legal adviser can help.
Frequently asked questions
How long does an exclusivity last?
Six months at most, according to the IPI summary.
Can I terminate before the end?
Yes. The contract must allow you to terminate without giving a reason. Capped compensation may be provided for.
Do I have to pay if my sale falls through?
The contract must state that no fee or commission is charged if the sale fails because of a suspensive or resolutive condition.
Can I sell myself during the exclusivity?
Not without risk: a penalty clause of at most 75% of the commission can sanction a breach of exclusivity. Reread your contract.
Can I sell without an agency?
