Signature électronique immobilier — clés d'appartement et mandat

Real estate use cases

All documents in the life of a real estate agency or property manager can be electronically signed on Certyneo, from transaction to rental management.

Residential lease

Furnished or unfurnished lease, Civil Code or July 6, 1989 law: send the contract electronically signed by the landlord, tenant and potentially the guarantor. All mandatory annexes (energy certificate, risk assessment, move-in inspection) can be integrated.

Move-in and move-out inspection

Sign remotely or on-site from a tablet: the joint inspection is signed by both parties, archived, and automatically linked to the initial lease.

Sales mandate

Simple or exclusive mandate, with or without right of first refusal: send it to the seller, collect their advanced electronic signature (AES) and archive for 10 years in compliance with Hoguet law obligations.

Property management mandate

Multi-year management mandate signed by the owner, with limited power of attorney delegation. Automatic renewal reminders before expiration.

Purchase agreement

Purchase agreement signed remotely by buyer and seller, with deposit mentioned and SRU 10-day withdrawal period automatically timestamped by the audit trail.

Joint guaranty deed

Guarantor commitment signed by the guarantor with legal handwritten notices (article 22-1 of the 1989 law) converted into electronically signed fields and traced in the audit trail.

Why Certyneo for real estate

Six concrete benefits for your transaction, management and property administration teams.

File completed in 48 hours

Instead of multiple back-and-forth mailings or physical appointments, the entire file (lease, guaranty, move-in inspection, annexes) is signed by all parties in 24 to 48 hours.

Reduction in logistics costs

No more printing, registered mail, scanning or travel expenses. According to FNAIM studies, digitization saves between €15 and €30 per rental file.

Optimized mobile signature

Your tenants and buyers sign from their phone in 2 minutes, without downloading an app. French-language experience, accessible and reassuring.

Enhanced probative value

Advanced signatures (AES) compliant with eIDAS: dual OTP identification via email + SMS, timestamped audit trail, evidence admissible in all courts.

10-year archiving included

All your mandates, leases and purchase agreements are archived for 10 years with probative value, a duration compliant with the document retention obligations of regulated real estate professions.

Intelligent multi-signatory

Two roommate tenants, a landlord and their agent, a joint guarantor: Certyneo orchestrates all signatories (in series or in parallel) with automatic reminders.

Time saved per file

In real estate, the time lost between a property proposal and actual signature represents a direct loss of income: cancellations, leases falling through, sales agreements dragging on. According to sector studies, electronic signature enables:

-70% administrative time per lease file, according to FNAIM studies on digitalization.
€15–30 saved per file on logistics costs (printing, certified mail, scanning, travel).
Cancellation rate cut in half thanks to signature speed — less delay means fewer opportunities for another property to attract the tenant or buyer.

Compliance with ALUR, ELAN, SRU, and Hoguet law

Electronic signature in real estate operates within a specific legal framework. Certyneo covers all applicable regulations.

July 6, 1989 law & ALUR law

The ALUR law (2014) and its implementing decrees govern the content of residential leases and appendices (EPC, risk disclosure, information notice). All mandatory documents can be bundled in a single Certyneo envelope for simultaneous signature.

ELAN law (2018)

The ELAN law explicitly recognized the validity of electronically signed private acts in real estate and encouraged digitalization of lease relationships. Certyneo enables the entire lease lifecycle (signature, amendments, renewal, termination).

SRU law — withdrawal period

For the compromise of sale of a residential property, the 10-day withdrawal period (CCH Article L271-1) begins from the first presentation of the signed document. Certyneo timestamps this date precisely and exports proof in case of dispute.

Hoguet law & Civil Code

The Hoguet law requires retention of mandates for 10 years. Our plans include this archiving with probative value by default. Article 1367 of the French Civil Code recognizes electronic signature as equivalent to handwritten signature.

Frequently asked questions in real estate

Is a residential lease signed electronically legal in France?

Yes, without ambiguity. The ELAN law (2018) explicitly confirmed the validity of leases in electronic form, and article 1367 of the French Civil Code recognizes electronic signature as equivalent to handwritten signature. Mandatory annexes (EPC, risk assessment, notices) can also be signed electronically.

How do I comply with the SRU 10-day withdrawal period for a compromise?

Certyneo precisely timestamps the date of signature of the agreement by both parties. The 10-calendar-day period (article L271-1 of the French Housing Code) runs from that date. You can export at any time the signature certificate with qualified timestamp to prove the start date of the period.

Are handwritten guarantor joint-and-several notes possible electronically?

Yes. French case law admits that handwritten notes required by Article 22-1 of the 1989 law can be entered and signed electronically, provided the guarantor actually reproduces them themselves (not a pre-filled copy-paste). Certyneo offers a mandatory input field with validation and timestamping.

Can two people sign a condition report in the same location?

Yes. Certyneo offers an "in-person signature" mode: both parties sign successively from the same tablet or smartphone during the visit, with strong ID (SMS OTP) for each. The audit trail preserves the timestamp and geolocated IP.

Is Certyneo compatible with Hektor, AC3, SPI, Immo-Facile?

Yes, via Zapier, Make, and our webhooks — there is no certified native connector on these software yet. Certyneo exposes a direct REST API and real-time webhooks to feed signature status back into your CRM. A native connector on one of these software is available on request: our integration team can support a custom deployment based on your stack and volume.

How long are signed leases and mandates archived?

Our plans include 10-year archival with probative value, which meets the document retention obligations under the Hoguet Law for mandates and standard durations for residential leases. Documents remain downloadable at any time from your dashboard.

How much does Certyneo cost for a real estate agency?

Our pricing starts with a free plan to test the service. Paid plans are based on the volume of envelopes sent per month, with tiers designed for agencies (5, 20, 100 files/month). See our /pricing page for details.

Can you have multiple documents signed in a single envelope?

Yes. A Certyneo envelope can contain multiple PDFs (lease + DPE annexes + risk assessment + security deposit). The signer reviews them in a single flow, signs once at the end, and the audit trail covers the entire package.
