Hosting a relative, a friend, or a family member without asking for any financial contribution is a common act of generosity, but it is not without legal and tax consequences. In France, this situation is governed by strict rules that impact both the host and the guest, particularly regarding social benefits, taxes, and housing rights. Whether you are a homeowner, a tenant, or a foreign resident seeking to regularise your status, discover everything you need to know to host someone for free legally and without any unpleasant surprises.

Free housing (hébergement à titre gratuit) consists of making a property (or a portion of it) available to a person without requiring any rent in return. From a legal standpoint, this situation is akin to a loan for use (prêt à usage, historically called a commodat), governed by Articles 1875 et seq. of the French Civil Code (Code civil).
According to Article 1875 of the Civil Code, a loan for use is a contract by which one of the parties delivers an item to another to use it, on the condition that the borrower returns it after having used it. This free-of-charge nature is essential: if any financial contribution, even minimal, is required, the relationship can be reclassified as a standard residential lease, subject to the law of 6 July 1989, which grants the tenant very strong legal protection (particularly regarding lease duration and the winter eviction truce, the trêve hivernale).

Welcoming someone into your home for an extended period (generally more than 3 months) leads to important administrative changes for both parties.
This is often where the financial consequences are most significant and immediate.
> Practical Example No. 1: Impact on RSA and CAF Benefits
>
> Let us take the example of Pierre, who receives the basic RSA of approximately €635 per month and lives alone in his flat. Pierre decides to host his friend Thomas, who is unemployed and has no resources, for free for one year.
>
> Upon declaring this situation to the CAF, Thomas will be considered housed for free. The CAF will apply a housing deduction of approximately €77 (an amount that varies depending on the household composition) which will be deducted from Thomas's RSA if he applies for it, as he has no rent to pay. On his end, if Pierre was receiving housing benefits calculated solely on his single status, his entitlement might be reassessed by factoring Thomas's presence into the household, which could lead to a reduction in his own solidarity allowances.

A proof of accommodation certificate (attestation d'hébergement or certificat d'hébergement) is an official statement written on one's honour by the host. It serves as proof of address (justificatif de domicile) for the guest in their administrative procedures (opening a bank account, applying for an identity card, applying for a residence permit (titre de séjour), registering with France Travail (the French unemployment agency), etc.).
To be legally valid, the process must follow these precise steps:
The certificate alone is not enough. It must always be accompanied by three key documents:
1. A copy of a valid ID of the host (national identity card, passport, or residence permit).
2. A copy of an ID of the guest.
3. A recent proof of address (less than 3 months old) in the host's name (electricity, gas, water, landline telephone/internet bill, or the latest tax notice).
The certificate can be handwritten or typed, but it must imperatively be signed by the host's hand. It must contain the following information:
> DECLARATION OF ACCOMMODATION ON HONOUR
>
> I, the undersigned, Mr/Ms [Host's Surname and First Name], born on [Date of birth] in [Place of birth], residing at [Host's full address],
>
> Hereby certify on my honour that I am hosting at my home, free of charge, Mr/Ms [Guest's Surname and First Name], born on [Guest's date of birth] in [Guest's place of birth], of [Nationality] nationality, since [Start date of accommodation].
>
> I am aware of the criminal penalties incurred for making a false declaration.
>
> Signed in [City], on [Current Date].
>
> Signature of the host:

Hosting someone is an act of solidarity, but a lack of formal agreements can quickly lead to intractable conflicts.

> Practical Example No. 2: The Trap of Financial Contributions
>
> Marie is a tenant of a 3-room flat in Lyon with a rent of €900. She decides to host her cousin Lucas, a young worker. To help him out, she offers him rent-free housing but asks him to transfer €300 per month by bank transfer to "contribute to overall costs" (internet, electricity, food).
>
> After a year, the relationship deteriorates and Marie asks Lucas to leave within 2 weeks. Lucas refuses. In court, the regular monthly transfers of €300 without precise justification of actual costs are interpreted by the judge as disguised rent. The free housing is reclassified as an unauthorised sublet. Marie risks having her own lease terminated by her landlord and finds herself stuck, as she cannot evict Lucas without respecting the legal notice periods of the 1989 tenancy law.

There is no legal time limit under French law. You can host a person for a few days, several months, or years. The agreement between the host and the guest prevails. However, to prevent a permanent right of occupancy from establishing itself, it is highly recommended to sign a loan for use agreement specifying an end date or terms of notice (for example, a 2-month notice period).
Yes. In France, aid to irregular stay when it is purely humanitarian and without any counterparty (what was historically referred to as the "solidarity offence" or délit de solidarité) has been significantly relaxed. The free housing of an undocumented foreigner by an individual does not constitute a criminal offence, provided there is no financial or material counterparty (Article L. 823-1 of the Code on the Entry and Stay of Foreigners and the Right to Asylum - CESEDA).
If no written contract has been signed, the guest is considered an occupant without right or title (occupant sans droit ni titre) once you notify them of your wish to end the arrangement. You must send them a formal notice to leave the premises by registered letter with acknowledgment of receipt (lettre recommandée avec accusé de réception - LRAR). If they refuse to leave, you must under no circumstances change the locks or throw out their belongings (which would constitute unlawful entry/trespass, a crime punished by law). You must petition the judicial court (tribunal judiciaire) to obtain an eviction order, a procedure that requires the intervention of a bailiff (commissaire de justice, formerly huissier).
Yes, this is highly recommended. Even if they are covered for certain damages under the host's roof via the host's insurance, the guest should take out personal civil liability insurance (assurance responsabilité civile) to cover damages they might cause to third parties outside the home or to the host themselves.
