The PDF you download is in French — that is the language it has to be filed in, so it is not translated. Everything on this page is here to tell you what it says.
For an unmarried couple without a PACS who are asked to prove they live together: by an insurer, a health fund, an employer, a landlord, a pension fund or a foreign authority. Both partners declare on their honour that they live together in a stable and continuous way (article 515-8 of the French Civil Code), since when and at which address, and enclose their ID and proof of address. The French document recalls the penalty for a false declaration (article 441-7 of the French Criminal Code).

Common questions
- Is a sworn declaration of cohabitation enough proof in France?
- Usually yes, with documents that back it up: proof of a shared address (lease, energy bill, tax notice), a joint account or a joint insurance policy. The body asking for it sets its own requirements: some health funds or foreign authorities want several documents. Some town halls issue a cohabitation certificate (certificat de concubinage); no law obliges them to, and the sworn declaration remains the commonest proof.
- What is the risk of signing a false declaration of cohabitation in France?
- Making a declaration stating facts that are materially untrue is an offence punishable by one year's imprisonment and a €15,000 fine (article 441-7 of the French Criminal Code), for each person who signs it. The body misled can also claim back any sums wrongly paid, such as a benefit or a refund. So give only the real date you started living together and the address where you actually live together.
- Does cohabitation give rights like marriage or a PACS in France?
- No. The law defines cohabitation (article 515-8 of the French Civil Code) but attaches almost no effects between the partners: no duty of support, no property regime, no right to inherit from the other without a will. Some bodies take it into account, such as insurers, health funds or the CAF, which counts the couple's joint resources. To organise the couple's property and expenses, a cohabitation agreement can complement this declaration.

Related documents
- Witness statement for court, model to copy by hand (France)
For someone giving written evidence in a civil case in France: a dispute between neighbours, at work or in the family, an accident. Article 202 of the French Code of Civil Procedure requires the statement to be written, dated and signed in the witness's own hand, so this document is not the statement itself but a model in French, filled with your details, to copy by hand on plain paper or on the official form Cerfa 11527, which is free and optional. It holds every compulsory statement. Enclose a copy of a signed ID document.
- Referral to the CADA after a refused document request (France)
For someone to whom a French administration refused a document, or did not answer within a month. The Commission d'accès aux documents administratifs (CADA) is approached free, preferably through the online form on its website. This letter, in French under French law, refers the matter by post: it names the administration, the date of the request, the documents and the answer received, and asks for a favourable opinion. Referral within two months of the refusal is compulsory before the administrative court.
- Sworn statement — attestation sur l’honneur (France)
For declaring in writing, on your own responsibility, a fact about yourself when an administration, employer, school, bank or landlord in France asks for it: family situation, lack of income, residence, a lost document, the accuracy of information. In French under French law, the statement identifies the declarant, sets out the facts, names the recipient if you wish and recalls the penalties for a false statement (article 441-7 of the French Criminal Code). For evidence in court, use the witness statement instead.
- Power of attorney for a specific act (France)
For asking someone to do one specific thing in your place when you cannot be there: collect a document, sign a lease or a contract, sell or buy a vehicle, represent you at an appointment. You describe the act, and the power covers that act only, until the date you choose (articles 1987 and 1989 of the French Civil Code). A voting proxy is made free on maprocuration.gouv.fr, and, for an act before a notary, the notary provides the power of attorney required. Signed by the principal, with a copy of their ID.
- Designation of a trusted person — personne de confiance (France)
For any adult who wants to name a relative, someone close or their GP as their trusted person: that person accompanies them in their dealings and medical appointments if they wish, and is consulted if they can no longer express their will (article L. 1111-6 of the French Public Health Code). The designation is written and co-signed by the person named; hospitals offer their own free form on admission. This French document is sold blank, filled in by hand, and revocable at any time.
- Revocation of a power of attorney, with notice to third parties (France)
For ending a power of attorney, general or for one act, given to a relative or anyone else. The French document holds two letters, sent the same day by registered post with proof of receipt: the revocation to the agent, asking for the original back and an account of what was done (articles 1993 and 2004 of the French Civil Code), and the notice to the bank or body that knows of the power. Without that second letter, third parties unaware of the revocation may still rely on the power (article 2005).
