Electronic Signature in Real Estate: Deposits and Rentals on the Move

The challenge of immediate closing in the real estate sector

In the real estate market, time is a critical factor. When a client finds the right property, whether for purchase or rental, interest is at its peak. However, the formalisation process is usually plagued by administrative delays: coordinating buyers’ and sellers’ schedules, printing dense deposit or rental contracts, and forcing parties to travel physically to the agency office.

This traditional flow generates clear inefficiencies and risks for the business:

1. Risk of deal collapse: Every hour between verbal agreement and contract signing is an opportunity for the client to cool off, keep searching or hear offers from competing agencies.
2. Operational costs and unnecessary travel: Sales agents lose valuable time printing copies, travelling to collect handwritten signatures and scanning documents to archive them in the system.
3. Lack of order in the legal file: Keeping visit sheets, exclusivity contracts and rental mandates in physical filing cabinets makes regulatory control difficult and exposes the agency to document loss.

The solution for optimising agency and developer commercial activity lies in equipping agents with electronic signature tools integrated into their real estate CRM to operate 100% on the move.

On-site deal closing: Simplicity and legal adaptability

Implementing a digital strategy allows real estate advisors to formalise any document directly from their smartphone or tablet during the property visit (under the BYOD approach), adapting signature level to operation risk:

1. Simple electronic signature: Instant for visit sheets and handover reports

For everyday procedures requiring immediate agility —such as the mandatory visit sheet clients sign before viewing a property, or key handover—, simple electronic signature is the ideal option. The agent shows the document on their mobile screen and the client signs with a quick finger stroke. The process takes seconds, eliminates paper entirely and leaves immediate legal record in the system.

2. Advanced electronic signature with OTP: Protection for deposit and rental contracts

When the procedure involves financial transactions or long-term commitments —such as a reservation contract, deposit agreement or definitive lease contract—, the flow is automatically elevated to advanced electronic signature with OTP verification. Parties sign remotely or in person by entering a one-time PIN code received by SMS on their mobile phones. This guarantees robust identity linkage that protects the agency and parties against any subsequent dispute.

3. API integration and unified signature envelopes

Through the signature API, the real estate CRM generates the contract by automatically filling in property, owner and tenant data. Through signature envelope functionality, the contract, photographic inventory of the property and SEPA direct debit mandate for monthly collection are unified in a single send.

Immutable evidence against non-payment or fee claims

Besides accelerating closings, contract digitalisation provides absolute legal protection for the agency legal department, especially useful for defending fee collection against clients attempting to bypass agency mediation.

Upon completion of the signing flow, the platform automatically generates a cryptographically sealed Evidence Document or Audit Trail. This technical certificate collects immutable timestamps of delivery, reading and signing, signatory IP addresses and cryptographic hashes of the original PDF. Integrated via webhooks, the final contract and its evidence are natively archived in the property record in the CRM, ready to be presented in court under the European eIDAS Regulation in case of conflict.

Frequently asked questions (FAQs)

Is it legally valid to sign a deposit or rental contract from a mobile?
Yes, it is completely valid and binding. The eIDAS Regulation grants full legal validity to simple and advanced electronic signature for real property contracting (excepting those procedures requiring notarial public deed by law, such as definitive purchase and sale).

How do several people sign a rental contract when they are not in the same place?
The platform, whether via console or API, allows configuring sequential or parallel signature flows. The CRM sends the contract automatically to the first owner; once they sign, the document goes to the second owner and finally to the tenants. The process completes 100% digitally without anyone meeting physically.

What happens if the lease contract includes an annex with the furniture inventory?
With signature envelope functionality, multiple files can be packaged (the contract PDF and an annex document with furniture photos) so the tenant reviews and validates the entire package in a single continuous consent flow.

Conclusion

Competitiveness in the modern real estate sector depends on execution speed and the ability to offer a comfortable experience to clients and owners. Continuing to manage contracts and visit sheets on traditional paper is an operational inefficiency that slows sales, raises administration costs and weakens operation control.

Implementing a flexible simple and advanced electronic signature strategy integrated into your management tools transforms your agency into a high-efficiency engine. The organisation eliminates bureaucracy, secures its commissions with irrefutable evidence and allows its agents to close deals immediately in the field.
