Offer to purchaseOffre d'achat

A written, signed offer from the buyer to buy a named property at a stated price, with a validity date and usually a loan condition. If the seller accepts it in writing without changes, the sale is concluded. The parties then sign a compromis de vente and, later, the notarial deed.

Use it after a visit, when you want to buy and want to state your price and conditions in writing. The law does not require it, but an accepted offer binds you: you cannot withdraw once the seller accepts. Send it to the seller or to the estate agent. For a flat, ask for the co-ownership documents from the syndic before you sign the offer.

Key facts

Applies to
Whole country. The text is in French and written for the Brussels-Capital Region; the offer rules come from the federal Civil Code and apply in all three regions.
When an offer binds
It must contain all essential terms, at least the property and the price (Civil Code art. 5.19).
Withdrawal by the buyer
Not possible once the seller accepts without changes (Notaire.be).
Validity period
Irrevocable for the period stated in the offer, or for a reasonable period if none is stated (art. 5.19).
Acceptance
The sale forms when the acceptance reaches the buyer (art. 5.21). Changes make it a new offer. Silence is not acceptance (art. 5.20).
Deposit
Usually 5% to 10% of the price, paid at the compromis into the notary's escrow account, never to the seller (Notaire.be).
Co-ownership information
Syndic's documents due before the offer is signed. The statement of debts is due within 30 days (Civil Code art. 3.89, § 5).
Brussels tenant's right of preference
A 9-year main-residence tenant has 30 days from notification to buy at the same price and terms (Brussels Housing Code art. 247/2).

      This is a promise to pay later. The escrow account protects the deposit if the sale fails or the seller has creditors.

Formalities

  1. No form, witness or notary is required.
  2. Sign and date the offer. Keep proof of the date the seller received it: a registered letter, an email with a reply, or a copy the agent signs for receipt.
  3. The seller must accept in writing.
  4. Pay no money to the seller with the offer. The deposit comes later, at the compromis, into the notary's escrow account.
  5. For a lot in a co-ownership, the seller or the agent must give you the syndic's information before you sign the offer (Civil Code art. 3.94).
  6. In Brussels, a home let under a 9-year main-residence lease carries the tenant's right of preference. Any sale is conditional on the tenant not using it.
  7. In Flanders and Wallonia the offer rules are the same. Registration duties and the seller's certificates differ.

Common mistakes

  • Making an offer without a loan condition when you need a loan. If the seller accepts, the sale is concluded and you must pay the price.
  • Leaving out the validity date. Without one, the offer stays irrevocable for a reasonable period, which may be long (art. 5.19).
  • Paying a deposit to the seller or the agent with the offer. Pay nothing until the compromis, and then only into the notary's escrow account.
  • Offering on a flat before you have the syndic's documents: reserve fund, arrears, works voted and the general meeting minutes of the last 3 years.
  • Treating a seller's reply with a new price as an acceptance. It is a counter-offer, and nothing is agreed until you accept it.
  • Negotiating by text message. A message can be used as a start of proof that you made an offer.
  • Ignoring a sitting tenant in Brussels. If the home is let under a 9-year lease, the tenant can buy in your place at the same price.
