Real estate rental generates the majority of disputes handled by the departmental conciliation commission. A significant portion of these conflicts is based on checks that neither the landlord nor the tenant carried out before signing the lease. We observe that the most costly disputes do not concern the rent itself, but rather overlooked documentary points beforehand.
Verification of the landlord’s identity and rental fraud
Before any payment, even a simple security deposit, the landlord’s identity must be formally verified. When the owner is a natural person, the correspondence between the title of ownership and the presented identity document is the minimum requirement. When the landlord is a real estate investment company (SCI), we recommend a search in the national business register (INPI) to confirm the legal existence of the structure and the identity of its manager.

Recent recommendations also emphasize verifying the notary possibly mentioned in the advertisement, via the official directory of the Chamber of Notaries. This reflex remains marginal among prospective tenants, even though it neutralizes the majority of fraud attempts, particularly those multiplying on classified ad platforms. Content that details these verifications in a methodical approach, such as the practical guide on Info Immobilier, remains rare compared to the mass of general articles.
A technical point often overlooked: if the advertisement mentions a management mandate entrusted to an agency, ask for the professional card number (carte G) and verify it with the issuing Chamber of Commerce. The absence of this number on contractual documents constitutes an irregularity that justifies not proceeding with the process.

DPE ranking and rental restrictions
The energy performance diagnosis now conditions the very possibility of renting a property. Gradual restrictions on energy-inefficient properties are changing landlords’ strategies well beyond a simple display obligation. A poorly rated property can no longer be subject to a rent increase, and the most energy-consuming properties are gradually being removed from the legal rental market.
For the tenant, checking the DPE ranking before signing the lease is not just a matter of comfort. It is a leverage for direct negotiation on the rent amount and a protection against disproportionate energy charges. A property rated F or G implies heating bills that can represent a budget item as heavy as the rent itself in certain areas.
For landlords, the question arises in terms of financial arbitration:
- Engaging in energy renovation work to keep the property on the rental market, with a return on investment that heavily depends on the geographic area and the type of property
- Accepting a longer rental vacancy if the property no longer meets regulatory criteria, incorporating this cost into the profitability calculation
- Revising the rent positioning downward to compensate for an unfavorable DPE and attract candidates nonetheless
We recommend that owners do not wait for the regulatory deadline to initiate an energy audit. Anticipating the work allows for smoothing its cost and avoiding a sharp depreciation of the property.
Lease and inventory: clauses that truly protect
The standard lease imposed by the ALUR law has reduced the drafting leeway, but has not eliminated the gray areas exploited by some landlords. The resolutory clause for unpaid rent, for example, only takes effect if it is drafted in the exact terms provided by the text. An approximate formulation renders it unenforceable.
The inventory remains the most underestimated document in the rental relationship. An imprecise entry inventory deprives the landlord of any recourse in case of degradation. The mentions “good condition” or “correct condition” are not sufficient. Each element (floor coverings, walls, sanitary equipment, joinery) must be described with its actual condition, ideally accompanied by dated photographs.
For the tenant, vigilance focuses on one specific point: any reservation not mentioned at entry will be presumed to be their responsibility upon exit. The timeframe to complete the inventory after handing over the keys exists, but its use remains unknown. It allows for reporting defects not visible during the initial visit (humidity issues that appear after a few days, heating malfunctions detectable only during the heating period).
Formalization of exit and return of the security deposit
The end of the lease concentrates a high proportion of rental disputes. Recent administrative guides emphasize the rigorous formalization of the exit process, as this is when the absence of precise documents costs the most.
The notice given by the tenant must respect the applicable notice period (variable depending on the area and type of rental). A notice sent by simple mail, even received by the landlord, does not trigger the legal deadline. Only registered mail with acknowledgment of receipt, a bailiff’s act, or hand delivery against signature are legally valid.
The return of the security deposit follows strict deadlines:
- One month after the exit inventory if it is consistent with the entry inventory
- Two months in case of discrepancies, with the landlord required to justify each deduction with quotes or invoices
- Beyond these deadlines, the tenant can claim an increase in the amount due, calculated based on the monthly rent
We observe that the majority of abusive deductions from the security deposit thrive due to hastily conducted entry inventories. The best investment of time for a tenant remains the thirty minutes spent detailing the inventory on the day of key handover.

Real estate rental does not forgive documentary approximation. A well-drafted lease, a verified DPE, a confirmed landlord identity, and a thorough inventory form a foundation that prevents nearly all common disputes. The time spent on these checks beforehand is always less than that absorbed by a dispute once it has begun.
