A tenant signs their lease on the 15th of the month but only receives the keys on the 1st of the following month. From when should they start paying rent? And when does the lease actually end, on the day they return the keys or at the expiration of the notice period? These two moments, signing and taking possession, do not always coincide, and the confusion between the two regularly generates conflicts between landlords and tenants.
Rent and taking possession: the costly gap
The effective date of the lease corresponds to the moment when the contract produces its legal effects. In practice, it is the date from which the tenant is liable for rent and charges. It must be included in the rental agreement.
This date does not necessarily correspond to the signing date. A lease can be signed several days, or even weeks, before moving into the property. When the gap is short (a few days), it is not necessary to redo the contract. The lease simply states an effective date different from the signing date.
When the delay exceeds a week and is due to the tenant, the landlord can demand payment of the rent from the effective date specified in the contract, even if the tenant has not yet moved in. Understanding the effective date of the lease and key handover helps anticipate this type of situation before it escalates.
If the delay is attributable to the landlord (unfinished work, property not available), the situation reverses: the tenant owes nothing as long as they do not have access to the property, and the effective date must be adjusted accordingly.
Key handover at the end of the lease: what really stops the rent
Are you leaving your property and thinking that returning the keys is enough to settle everything? The legal reality is more nuanced.
Notice period and key return are not the same
A ruling from the Court of Cassation on June 4, 2026, clarified a point often misunderstood. The exit inventory and the key handover only prove the physical release of the property. They do not demonstrate that the landlord waives the remaining rent due until the end of the notice period.
In other words, a tenant who returns their keys two weeks before the end of their notice period remains liable for rent until the scheduled expiration. The early return of the keys does not automatically shorten the payment period.
To whom to return the keys for it to be valid
The keys must be returned to the landlord in person or to their authorized representative with a valid mandate (a real estate agency, for example). Returning the keys to the building caretaker does not count as a return. If the landlord disputes having received the keys, it is up to the tenant to prove that they were indeed returned.
To secure this step, several concrete precautions are necessary:
- Have a key handover report signed, mentioning the date, number of keys, and the identity of the recipient
- Send the keys by registered mail with acknowledgment of receipt if the landlord refuses to come or is unreachable
- Keep a copy of the exit inventory signed by both parties, associated with the return document
Security deposit: the deadline starts from the keys
The handover of the keys marks the starting point for the security deposit return period. For residential leases, the landlord has one month if the exit inventory matches the entry inventory, and two months in case of observed damages.
The deadline starts from the actual date of key handover, not from the end of the notice period or from the exit inventory date if they do not coincide. This detail changes everything when a landlord delays in retrieving the keys: the tenant has an interest in proving the exact date of return.
Commercial lease: different rules since 2026
For commercial leases, the law simplifying economic life has modified the deadlines. The landlord must return the guarantees within a maximum of three months from the key handover. This deadline extends to six months for non-monetary guarantees such as a bank guarantee or a mortgage.
This reform establishes the key handover as the legal starting point for the return deadline in the Commercial Code (article L.145-40 modified). Before this amendment, the ambiguity regarding the starting point fueled long and costly disputes.
Exit inventory and end of rental obligations
The exit inventory and the key handover are two distinct acts, even if they often occur on the same day. The inventory assesses the condition of the property. The key handover ends the occupation.
When both occur before the end of the notice period, this does not relieve the tenant of their obligation to pay the remaining rent. Only the expiration of the notice period ends the obligation to pay rent.
In case of a dispute regarding the condition of the property at the time of exit, the tenant who has not received their copy of the exit inventory retains recourse. The absence of the document’s handover by the landlord can work in favor of the tenant before a judge, as the burden of proof for damages then rests on the landlord.
- The exit inventory must be contradictory, conducted in the presence of both parties or their representatives
- If the landlord refuses to conduct the inventory, the tenant can call upon a bailiff, whose fees are shared
- Any disagreement regarding damages must be noted on the document before signing
The end of a rental lease is based on a precise chronology where each act produces different legal effects. Confusing notice, key handover, and exit inventory exposes both the tenant and the landlord to financial losses. Keeping a written record of each step remains the best protection for both parties.
