In real estate, the time lost between proposing a property and the actual signature translates directly into missed revenue: drop-outs, rentals that fall through, preliminary agreements that drag on. According to industry studies, electronic signatures deliver:

Electronic signatures in real estate fit into a precise legal framework. Certyneo covers every applicable statute.
The ALUR Act (2014) and its implementing decrees govern the content of the tenancy agreement and its annexes (energy performance certificate, risk assessment, information notice). Every mandatory document can be bundled into the same Certyneo envelope for simultaneous signing.
The ELAN Act explicitly recognised the validity of electronic private deeds in real estate and encouraged digitising the landlord-tenant relationship. Certyneo covers the whole lease lifecycle (signing, amendments, renewal, termination).
For the preliminary sales agreement on a residential property, the 10-day withdrawal period (Article L271-1 of the French Construction and Housing Code) starts from the first presentation of the signed document. Certyneo timestamps this date precisely and exports the evidence in the event of a dispute.
The Hoguet Act requires mandates to be retained for ten years. Our plans include this probative-value archiving by default. Article 1367 of the Civil Code recognises electronic signatures as equivalent to handwritten signatures.
Yes, without any ambiguity. The ELAN Act (2018) explicitly confirmed the validity of electronic leases, and Article 1367 of the Civil Code recognises electronic signatures as equivalent to handwritten signatures. Mandatory annexes (energy performance certificate, risk assessment, notice) can also be signed electronically.
Certyneo timestamps precisely the date on which both parties sign the preliminary agreement. The 10 calendar-day period (Article L271-1 of the French Construction and Housing Code) starts from that date. You can export the signature certificate with an RFC 3161 timestamp at any time to prove when the period began.
Yes. Since 1 January 2022, Article 1175 of the Civil Code no longer excludes guarantees from electronic signature. The guarantor must personally affix the statement provided for by Article 2297 of the Civil Code, to which Article 22-1 of the 1989 Act refers; in electronic form, the process must ensure that only the guarantor can affix it (Article 1174) — typed by the guarantor themselves, not pre-filled text or a copy-paste. Certyneo offers a mandatory entry field with validation and timestamping.
Yes. Certyneo offers an "in-person signing" mode: both parties sign successively from the same tablet or smartphone during the visit, with strong identification (SMS OTP) for each. The audit trail retains the timestamp and the geolocated IP.
Yes, through several integration channels: direct REST API, webhooks to push signature statuses, and Zapier/Make connectors covering these platforms. Our integrations team can also support a bespoke rollout tailored to your stack.
Our plans include ten-year probative-value archiving, which matches the Hoguet Act retention obligation for mandates and the usual durations for tenancy agreements. Documents remain downloadable at any time from your dashboard.
Our pricing starts with a free tier to trial the service. Paid tiers are based on the volume of envelopes sent per month, with bands designed for agencies (5, 20, 100 files per month). See our /pricing page for details.
Yes. A Certyneo envelope can contain several PDFs (lease + energy performance certificate + risk assessment + surety). The signer walks through them in a single flow, signs once at the end, and the audit trail covers the entire package.
