Real Estate: A Sector with High Contract Volume
Sales mandates, property management mandates, leases, purchase agreements, inventory reports, amendments: a real estate agency processes hundreds of documents per month. Electronic signature drastically shortens transaction cycles.
Commonly Signed Documents
- Sales Mandate (exclusive, non-exclusive, semi-exclusive)
- Property Management Mandate
- Residential Lease (unfurnished, furnished)
- Commercial lease, professional lease
- Purchase agreement / promise of sale (if entrusted to the agency, otherwise notary)
- Entry and exit inventory reports
- Joint guarantor contracts
- Lease amendments (tenant change, rent adjustment)
Recommended Level
For a mandate or a lease, advanced signature (AES) is the standard — significant contractual stake, long-term rental relationship. Inventory reports can be in simple electronic signature (SES).
Purchase agreements generally go through the notary who issues their own qualified signature.
Benefits for the Agency
- Remotely signed mandates: no need for an appointment at the agency to collect the seller's signature
- Accelerated leases: a file validated in the morning, lease signed in the afternoon, tenant in place the next day
- Fewer no-shows: the signature rate increases significantly when the tenant can sign from their couch
- Centralized complete file: lease + guarantee + inventory reports in one space
Integration with Real Estate Software
Agencies use Apimo, Hektor, PERISCOPE, Immofacile. Modern electronic signature interfaces via API to generate documents, send for signature, and retrieve the signed PDF into the client file.
Common Mistakes
- Sending a lease without mandatory annexes (EPC, diagnostics, information notice)
- Using SES for an exclusive mandate (weak proof in case of dispute)
- Not keeping the audit trail (lease duration + 5 years)
- Having the lease and guarantee signed separately (risk of inconsistency)
Concrete Case: Remote Lease Signature
An apartment in Paris assigned to a tenant based in Lyon. Timeline:
- Monday morning: file validated by the agency
- Monday 10am: sending via AES of lease + annexes + joint guarantee (3 signers: tenant, guarantor, landlord)
- Monday 3pm: all signed
- Tuesday: key handover
Three weeks gained compared to the traditional paper cycle.
