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.

Tenancy agreement

Furnished or unfurnished lease, Civil Code or 6 July 1989 law: send the contract electronically signed by the landlord, tenant and possibly the guarantor. All mandatory annexes (EPC, risks, inspection report) can be integrated.

Entry and exit inspection report

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

Sale 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 accordance with Hoguet law obligations.

Rental management mandate

Multi-year management mandate signed by the owner, with framed power of attorney. Automatic reminders for renewals before expiry.

Sales agreement

Agreement signed remotely by buyer and seller, with deposit mentioned and 10-day SRU withdrawal period automatically time-stamped by the audit trail.

Joint guarantee deed

Guarantor commitment signed by the guarantor with mandatory handwritten particulars (article 22-1 of the 1989 law) converted to 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 within 48 hours

Instead of multiple postal exchanges or physical meetings, the entire file (lease, guarantee, inspection report, annexes) is signed by all parties within 24 to 48 hours.

Reduction in logistics costs

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

Optimised mobile signature

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

Enhanced probative value

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

10-year archiving included

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

Intelligent multi-signer

Two co-tenants, a landlord and their representative, a joint guarantor: Certyneo orchestrates all signers (in series or in parallel) with automatic reminders.

Time saved per file

In real estate, time lost between a property proposal and actual signature represents direct lost revenue: withdrawals, rentals that fall through, compromises that drag on. According to sectoral studies, electronic signature enables:

  • 70% reduction in administrative time per rental file, according to FNAIM studies on paperless management.
  • £15 to £30 saved per file on logistics costs (printing, registered mail, scanning, travel).
  • Withdrawal rate cut in half thanks to signature speed — less delay means fewer opportunities for another property to attract your tenant or buyer.

Compliance with ALUR, ELAN, SRU and Hoguet laws

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

Law of 6 July 1989 & ALUR law

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

ELAN law (2018)

The ELAN law explicitly recognised the validity of electronic private deeds in real estate matters and encouraged paperless rental relationships. Certyneo enables the entire lease lifecycle (signature, amendments, renewal, termination).

SRU law — withdrawal period

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

Hoguet law & Civil Code

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

Frequently asked questions in real estate

Is a residential lease signed electronically legally valid in France?

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

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

Certyneo precisely timestamps the date of signature of the compromise by both parties. The 10-calendar-day period (article L271-1 of the CCH) runs from this date. You can export the signature certificate with qualified timestamping at any time to prove the start of the period.

Are handwritten guarantor statements possible electronically?

Yes. French case law accepts that the handwritten statements required by article 22-1 of the 1989 law can be typed 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 at 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 identification (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 for these software yet. Certyneo exposes a direct REST API and real-time webhooks to feed signature statuses back into your CRM. A native connector for one of these software is available on request: our integration team can support you with custom deployment based on your stack and volume.

How long are signed leases and mandates archived for?

Our plans include 10-year archiving with probative value, which meets the storage obligations of the Hoguet Law for mandates and standard periods 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). Visit our /pricing page for details.

Can you sign multiple documents in a single envelope?

Yes. A Certyneo envelope can contain multiple PDFs (lease + DPE schedules + 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.
