What can a real estate developer sign electronically?
Real estate promotion involves two distinct registers of deeds. The AUTHENTIC DEED OF SALE in the state of future completion (VEFA) is obligatorily received by a notary (art. L261-11 of the Construction and Housing Code): it falls under notarized electronic authentic deed, not covered by Certyneo — exactly as for conventional sales. On the other hand, the RESERVATION CONTRACT (or preliminary contract of the VEFA, art. L261-15 CCH), which precedes the sale and commits the reservatary, is a deed under private seal: it can be perfectly signed electronically. The same applies to all private seal deeds of the developer: commercialization mandates entrusted to agencies, subcontracting and supplier contracts, commercial leases of new premises, amendments. Certyneo dematerializes this entire private seal contractual chain with an eIDAS level of evidence, by precisely time-stamping the starting point of the reservatary''s legal withdrawal period.
Why sign electronically in real estate promotion?
Reservation contract signed remotely
The preliminary reservation contract (art. L261-15 CCH) is signed online by the reservatary from their home, with identity verified by SMS OTP. The guarantee deposit and mandatory mentions (estimated price, execution deadline, housing characteristics) are secured in the flow.
Time-stamped withdrawal period
The reservatary has a 10-day withdrawal period (art. L271-1 CCH). Qualified time-stamping precisely dates the first presentation of the signed contract, providing irrefutable proof of the starting point of the period in case of dispute.
Industrialized multi-lot commercialization
A new program consists of dozens of lots to reserve. Reusable templates and multi-document envelopes allow reservation contracts to be issued in sequence, and real-time monitoring of the commercialization status lot by lot.
Enforceable audit trail
Each deed is delivered with a proof PDF: signatory identity verified by SMS OTP, qualified time-stamping, SHA-256 hash, IP. Enforceable in case of dispute with a reservatary, a commercialization representative or a subcontractor, and archived for 10 years.
4-step procedure
From reservation to archival, in less than 5 minutes per lot.
1. Prepare the reservation contract
Preliminary VEFA contract (art. L261-15 CCH) pre-filled: designation of the dwelling, estimated price, execution deadline for works, guarantee deposit amount, restitution conditions. Mandatory mentions locked.
2. Add the reservatary(ies)
Reservatary(ies), co-buyers, possible guarantor. As a couple or in undivided ownership, add each signatory under penalty of partial nullity. Each receives a personal secure link with SMS OTP.
3. Advanced signature + time-stamping
Identity verification by SMS OTP, unique certificate, qualified time-stamping compliant with art. 26 of the eIDAS regulation. The signature date opens the countdown of the 10-day withdrawal period.
4. Monitoring and archiving
The signed contract and its audit trail are archived for 10 years with probative value. The marketing schedule is updated batch by batch. The final VEFA sale is then transmitted to the notary for the authentic deed.
Frequently asked questions
- Can a VEFA reservation contract be signed electronically?
- Yes. The reservation contract (preliminary contract for sale in future completion state, art. L261-15 CCH) is a private deed: no provision requires a handwritten signature. Article 1367 of the Civil Code recognizes electronic signatures as having the same value as handwritten signatures. Advanced signature (AES) is recommended given the deposit and the reservee''s commitments.
- Can the final VEFA sale deed be signed on Certyneo?
- No. Sale in future completion state must be established by authentic deed received by a notary (art. L261-11 CCH). The authentic deed of sale thus falls under notarized electronic authentic deed, outside Certyneo''s scope. Certyneo covers everything that precedes and surrounds this sale: reservation contract, marketing mandates, supplier contracts.
- How to secure the reservee''s 10-day withdrawal period?
- The reservee has a 10-day withdrawal period (art. L271-1 CCH), which runs from the first presentation of the signed contract. Qualified timestamping precisely dates this signature; you can export the certificate to prove the start of the period in case of dispute.
- Can the deposit be framed within the electronic contract?
- The reservation contract frames the deposit (capped by art. R261-28 CCH according to the completion timeline). Certyneo locks the mandatory provisions of the preliminary contract, but the collection of the deposit on escrow account remains managed by your notary or your banking establishment according to applicable regulations.
- Can marketing mandates be signed by agencies?
- Yes. Marketing mandates entrusted to agencies (holders of the T card) are private deeds, perfectly signable electronically in advanced signature. They are archived with their audit trail and, where applicable, numbered in the agency''s mandate register.
- What signature level for a reservation contract?
- Advanced signature (AES) recommended given the stakes (deposit, forecast price, completion timeline). It provides the presumption of reliability (art. 1367 Civil Code) enforceable without further demonstration, provided the eIDAS audit trail is produced.
- How long must reservation contracts be kept?
- At least 10 years (general statute of limitations), or more for documents from a program giving rise to warranties (perfect completion, decennial). Certyneo automatically archives each deed + its audit trail for 10 years, extension available.
- Are electronically signed reservation contracts enforceable?
- Yes — French case law unanimously recognizes electronic signatures compliant with eIDAS. The presumption of reliability of art. 1367 Civil Code makes advanced signature (AES) enforceable without further demonstration, provided the eIDAS audit trail delivered automatically by Certyneo is produced.
