Why should a real estate agent digitize?
The real estate agent holding professional card T (property transactions) or G (property management) is subject to strict contractual formalism imposed by the law of January 2, 1970 (known as the Hoguet Act) and its implementing decree of July 20, 1972. All acts signed with the client — mandate, amendment, termination — must contain precise mandatory provisions and be kept in a mandate register for 10 years (art. 72 of the decree). Digitization via advanced electronic signature makes it possible to: (1) save several days per file by avoiding physical signature meetings, (2) guarantee compliance with mandatory provisions through automatically controlled templates, (3) maintain a digital mandate register that is compliant and accessible in one click for any CCI or DGCCRF inspection.
Why sign electronically?
All digitized Hoguet acts
Simple sale mandate, exclusive mandate, property management mandate, commercial lease, residential lease, amendments, terminations, sales agreement. The Certyneo landing component natively covers each act with its specific legal framework and mandatory provisions.

Audit trail enforceable against DGCCRF

Frequently asked questions
- Can a real estate agent sign their mandates electronically?
- Yes, without restriction. No Hoguet provision requires handwritten signature. Article 1366 of the Civil Code recognizes electronic writing as having the same probative force as paper writing. Certyneo''s advanced signature (AES) meets probative requirements in case of dispute over commission or powers.
- How to maintain a compliant digital mandate register?
- Article 72 of the decree of July 20, 1972 requires maintaining a register with continuous numbering. Certyneo automatically assigns a number to each mandate (in order of signature), preserves the PDF + audit trail, and allows compliant Excel export. Compatible with CCI inspections.
- What to do in case of co-ownership or married couple?
- All co-owners must sign under penalty of partial nullity (art. 815-3 Civil Code for co-ownership, art. 1424 for community). Our multi-signatory flow handles sequential or parallel signature, each co-owner signing from their phone with individual SMS OTP.
- Does the exclusive mandate have a different legal regime?
- Yes — article 78 of the decree of July 20, 1972 requires that the exclusivity clause appear in a separate box on the front of the mandate, with mention of the period of irrevocability. Our exclusive mandate template automatically respects this formatting.
- What signature level for a real estate mandate?
- Advanced signature (AES) recommended given the financial stakes (commission, exclusivity penalty clause). It provides the presumption of reliability (art. 1367 Civil Code) enforceable without further demonstration.
- How long must mandates be retained?
- 10 years (art. 72 decree of July 20, 1972). Certyneo automatically archives each mandate + its audit trail for this duration, accessible in one click for any inspection or dispute.
- How much does electronic signature cost for a real estate agency?
- A free plan allows testing on 5 envelopes per month. Beyond that, paid plans start at a rate compatible with client refactoring (integration into agency fees). The rate includes 10-year archiving, eIDAS audit trail and digital mandate register.
- Are electronically signed acts enforceable in court?
- Yes — French case law unanimously recognizes eIDAS-compliant electronic signature. The presumption of reliability of art. 1367 Civil Code makes advanced signature (AES) enforceable without further demonstration, provided the eIDAS audit trail is produced (automatically delivered by Certyneo).
