The process of a real estate transaction, whether it involves a purchase, sale, or rental, entails a series of documents to be produced, verified, and signed. In recent years, online services have made it possible to carry out these real estate procedures without physical travel. The French regulatory framework, particularly the ALUR and ELAN laws complemented by the European eIDAS regulation, now recognizes the legal validity of most of these dematerialized procedures.
100% Digital Rental File: What the Legal Framework Really Allows
Rental agreements, inventory of fixtures, guarantee deeds: since January 1, 2022, the entire rental file can be signed electronically by both individuals and professionals, with full legal recognition. The ALUR and ELAN laws, combined with the eIDAS regulation, lay the foundation for this dematerialization.
Implementation decrees published between 2024 and 2025 have clarified the legal model for the inventory of fixtures and confirmed its validity when carried out and signed via an online application with advanced or qualified electronic signature. In practice, a landlord and a tenant can now conclude a lease, perform the entry inventory, and formalize the guarantee without any paper documents circulating.
However, this ability to conduct the process from start to finish remains underutilized. Many landlords and tenants are unaware that the joint guarantee itself can be signed remotely, provided that a signature level compliant with the eIDAS regulation is used. Platforms offering these online rental management services are gradually integrating these compliance levels, but not all do so with the same rigor.

Electronic Signature in Real Estate: Security Levels and Practical Limits
The electronic signature is not a monolithic block. The eIDAS regulation distinguishes three levels: simple, advanced, and qualified. For a sales mandate or a preliminary agreement, the advanced level is the minimum recommended by most professional organizations in the sector.
In contrast, for an authentic deed (final sale before a notary), a qualified electronic signature is mandatory, and only the notary can deploy it via the secure system of the profession. No public online platform currently allows for the signing of an authentic real estate sales deed.
What Can Be Signed Online and What Cannot
- Search or sale mandates, leases, inventories of fixtures, guarantee deeds: can be signed online with advanced or qualified signature
- Preliminary sales agreement (under private signature): can be signed online, but the parties retain a withdrawal period identical to the paper format
- Authentic sales deed: reserved for the notary, who uses their own qualified signature infrastructure
- Urban planning documents or technical diagnostics: produced by certified third parties, they can be transmitted digitally but their establishment remains subject to physical procedures (asbestos diagnosis, on-site energy performance diagnosis)
The confusion between these levels fuels legitimate distrust among some clients. A real estate agent offering online signing benefits from clearly explaining what type of signature is used and what legal guarantees arise from it.
Artificial Intelligence and French PropTech: A Rapidly Evolving Sector
The French PropTech ecosystem has seen a marked acceleration since 2025. According to recent sector analyses, approximately 35% of PropTech fundraising in France is related to the use of artificial intelligence. Automated property valuation, document sorting and analysis, generation of optimized listings: use cases are multiplying.
For individuals, these tools translate into concrete services. Some platforms offer a property valuation in just a few minutes by cross-referencing past transaction data with local parameters (proximity to transport, neighborhood development). Others automate the verification of the completeness of a rental file, reducing processing time for both agencies and prospective tenants.
Current Limits of AI Applied to Real Estate
Field feedback varies on the reliability of these automated valuations. An atypical property (non-standard size, degraded co-ownership, location in a redevelopment zone) often exposes the algorithms trained on average data. Algorithmic estimation remains a starting point, not a sale price.
The question of personal data protection also arises. Rental files contain sensitive information (tax notices, identity documents, pay slips). Online platforms handling these documents must comply with GDPR, but encryption levels and retention policies vary from one service to another. No unified sector label currently allows users to easily compare these practices.
Online Rental Management: What Platforms Change for Owners
Several online services now offer to handle rental management from start to finish: rent collection, reminders in case of unpaid rent, tax declarations, coordination of work. The business model generally relies on a percentage of the collected rent, lower than that practiced by a traditional agency.
The main advantage for an owner lies in centralization. Rather than juggling between an accountant, a tradesman, and a manager, a single interface brings together all flows related to the property. Rent receipts are generated automatically, and tax documents are pre-filled.
The available data do not allow for a conclusion that these platforms provide equivalent support in the case of complex disputes (eviction, severe damage, litigation in court). Human management, with a physical contact capable of traveling, retains an advantage in these tense situations. The choice between an online solution and a traditional agency therefore largely depends on the profile of the property and the level of rental risk.
The dematerialization of real estate procedures is progressing as the legal framework becomes clearer and tools gain maturity. For both individuals and professionals, checking the proposed signature level and compliance guarantees of a platform remains the first reflex before transferring sensitive documents.
