What is an exclusive real estate mandate?

The exclusive mandate (or "exclusive sales mandate") is a real estate sales mandate that grants a single real estate agent the exclusive right to present and sell the property for a period of irrevocability (often 3 months). During this period, the owner cannot mandate another agent or sell directly without paying the commission. Article 78 of decree no. 72-678 of 20 July 1972 requires that the exclusivity clause appear in a separate box on the front of the mandate, with mention of its irrevocability duration.

Why sign the exclusive mandate electronically?

Traced exclusivity clause

The legal challenge of an exclusive mandate is the traceability of consent to exclusivity. Advanced electronic signature (AES) precisely timestamps the moment of consent and captures the signatory''s identity, making exclusivity enforceable against the owner even in case of later dispute.

Multi-signatories (couple, co-ownership)

If the property belongs to multiple co-owners, all must sign the exclusivity clause under penalty of partial unenforceability. Our flow handles sequential or parallel signature, with each co-owner signing from their phone with their individual SMS OTP.

10-year archival included

In accordance with article 72 of the decree of 20 July 1972, the real estate agent must retain the mandate for 10 years. Certyneo automatically archives the mandate + its eIDAS audit trail for this entire duration — useful for producing the exclusivity clause in case of commission dispute.

Enforceable eIDAS audit trail

Each exclusive mandate is delivered with a proof PDF: identity of signatories, qualified timestamp, SHA-256 hash, IP geolocation, SMS OTP. Enforceable in case of dispute over the exclusivity clause, its irrevocability duration, or the commission due.

Frequently asked questions

What is the difference between a simple mandate and an exclusive mandate?
