A tenant occupying a property without a written contract, rented by a landlord who does not declare rental income, does he have the same protections as a standard tenant? The answer depends on several distinct legal mechanisms, sometimes contradictory in their practical effects. This article compares the situation of a tenant with a written lease and that of a tenant without a lease, then analyzes the concrete levers available to the latter in the face of an undeclared rental.
Written lease, verbal lease, and undeclared rental: comparative table of protections
The law of July 6, 1989 requires a written contract for any rental for primary residence use. Since Law No. 2024-322 of April 9, 2024, the refusal to establish a compliant contract exposes the landlord to one year of imprisonment and a €20,000 fine. However, case law recognizes the validity of verbal leases if there is evidence of occupation and payment.
The table below summarizes the differences in protection based on the form of the lease and the tax status of the rental.
| Criterion | Declared written lease | Verbal lease (not written) | Undeclared rental |
|---|---|---|---|
| Legal validity of the lease | Full | Recognized if proof of payment exists | The lease remains valid; the tax irregularity is that of the landlord |
| Right to remain in the premises | Yes, with legal notice | Yes, same conditions | Yes, unchanged |
| Obligation for decent housing | Yes (law 1989, art. 6) | Yes | Yes |
| Annual rent adjustment | Possible if written clause | Impossible (no clause) | Impossible |
| Security deposit | Regulated by the lease | Difficult to prove | Difficult to prove |
| APL paid to the landlord | Yes | Yes if lease regularized | Direct payment to the landlord compromised in rental permit zones |
| Sanctions for the landlord | No specific | Fine up to €20,000 | Tax adjustment, fines, penalties |
The rights of the tenant without a lease do not disappear due to the irregularity of the landlord. Article L.635-8 of the Construction and Housing Code specifies that renting without authorization is “without effect on the lease”.
Proof of verbal lease: what the tenant must gather
Without a written contract, the burden of proof rests on the tenant who wishes to assert their rights. The Court of Cassation has repeatedly confirmed that regular transfers and continuous occupation are sufficient to establish the existence of a verbal lease.
The admissible elements before a court are specific:
- Bank statements showing regular monthly transfers to the landlord, with an identifiable description (even a simple recurring transfer constitutes a clue)
- Written exchanges (SMS, emails, messages on an app) mentioning the housing, rent, or terms of occupation
- Rent receipts, even informal, or handwritten receipts signed by the landlord
- Testimonies from neighbors, mail received at the housing address, energy or internet bills in the tenant’s name
A tenant with these proofs is considered to have a rental contract under the 1989 law. They can approach the departmental conciliation commission or the judicial court.
Lack of proof: a situation that weakens both parties
If the tenant pays in cash without a receipt, the demonstration becomes much more complex. Cash payment without written trace deprives the tenant of their main legal lever. In this case, the landlord cannot easily prove an unpaid rent to initiate an eviction procedure.
This deadlock rarely benefits the tenant in the long term. Without proof of payment, it is impossible to request the reimbursement of a security deposit or contest a rent amount.
Indecent housing and undeclared rental: a remedy that remains open
The undeclared nature of the rental does not eliminate the landlord’s obligation to provide decent housing. Article 6 of the law of July 6, 1989 applies regardless of the tax status of the rental.
A tenant occupying an unsanitary property, without functional heating or posing health risks can approach the court even if no written lease exists. The landlord’s administrative irregularity never suspends their obligation of decency.
A landlord attempting to invoke the absence of a lease to escape their repair obligations finds themselves in a disadvantageous position. The judge will recognize the existence of a verbal lease and apply the same rules as with a written contract.
Rental permit and consequences on housing assistance
In municipalities that have established a rental permit, the landlord’s failure to comply with this obligation can have an indirect consequence for the tenant: the payment of APL directly to the landlord may be blocked. The tenant retains their right to assistance but must receive it themselves, complicating rent management.
This situation creates additional pressure on the landlord, who loses a mechanism for securing their rental income.
Regularization of the lease and the tenant’s interest in acting
The tenant has the option to request the landlord to draft a written lease compliant with the law. This right exists at any time during the rental relationship. If the landlord refuses, the tenant can approach the court to obtain the formalization of the contract.
Regularization offers concrete advantages for the tenant:
- Facilitated access to housing assistance, including direct payment of APL to the landlord
- Regulation of the security deposit and its return at the end of the lease
- Ability to contest a notice not complying with legal notice periods
- Enhanced protection in case of sale of the property (right of first refusal)
For the landlord, regularizing the situation helps avoid the criminal sanctions introduced by the 2024 law and regain the ability to apply a resolutory clause in case of non-payment.
The tenant without a lease facing an undeclared rental retains all the protections provided by the 1989 law, as long as they can prove their occupation and payments. The landlord’s fiscal or administrative irregularity does not remove any rights from the tenant, but it complicates the procedures for both parties. Building a solid proof file remains the first action to undertake for any occupant in this situation.
