A purchase offer travels today by email, by WhatsApp, sometimes on a paper form signed at the end of a viewing. It is valid that way: Belgian law imposes no particular form. The problem is not its validity, it is everything around it - who received it, when, what was passed on to the seller, and what can still be shown six months later. A digital offer does not change the law. It changes the trace.
The starting point: a link, not an account
The agency generates a link and a QR code per property. The prospective buyer finds them on the listing, in the viewing booklet or in the window, and opens them on their phone.
They download nothing. They choose no password. Many buyers will make a single offer in their lifetime: asking them to create an account for that means losing half of them before the first question. Identification goes through itsme, which they already use for their bank and their taxes.
What the buyer fills in
The form carries what an offer must contain to be usable:
- the price offered;
- the validity period of the offer, after which it lapses;
- the suspensive conditions chosen from the list the agency has authorised, with their amount and their deadline;
- any co-buyers, each invited to sign separately.
The wording itself is not written by the platform. It comes from the agency's template, loaded once and editable from its own workspace. That is a deliberate boundary: drafting an offer clause is legal advice, and a badly written clause costs tens of thousands of euros. The agency keeps its template, and the responsibility for its content.
The template is versioned. Each offer records the exact version that produced it, so that a later edit never rewrites what a buyer signed.
Signature, then delivery
Each buyer signs with itsme. The signature seals the document: it establishes who signed, what, and at what time. That is the subject of a separate guide, what an itsme signature proves.
From the last signature, the offer goes to the seller. Not the next day, not after review: the same second. The agent can neither filter it nor delay it. This is a deliberate transfer of power, and it reads both ways - the day a seller accuses their agent of having hidden an offer, the agent has the timestamped log that shows otherwise.
What the seller sees
The seller has their own workspace. There they see every offer made on their property, in order, with the time of signature and the associated proof. They accept, refuse or counter from that screen.
It is the seller who signs the acceptance. The agent advises. An acceptance signed by the agent exists only where a written, recorded and logged power has been granted: never by default, never implicitly.
Deadlines, once the offer is accepted
Acceptance forms the sale, but the file does not stop there: the financing condition runs, with its amount and its expiry. The circuit tracks those deadlines and warns before they lapse. It is the least spectacular and the most useful part - a forgotten financing deadline collapses a sale nobody wanted to lose.
Where the circuit stops
It stops at acceptance and at the tracking of conditions. On the way out, the platform produces a structured summary that the agent or the notary picks up to draft the preliminary contract.
Kiadah drafts neither preliminary contract nor deed, and is not an estate agent: the company negotiates no transaction and never holds funds. The preliminary contract calls for documents whose list differs from one region to the next - soil certificate, planning information, asbestos, building-management documents, pre-emption rights. That is the notary's trade, and that is where it begins.
