There is no single legal framework for moving certificates in France. No Cerfa form is specifically dedicated to them, and no national standard sets out their mandatory contents. This regulatory uncertainty leaves some flexibility in how they are drafted, but also calls for formal care to ensure the document is accepted by its recipient, whether an employer, landlord or public body.
Legal status of a sworn statement of moving
A moving certificate drafted as a sworn statement makes the signatory legally responsible for its contents. Making a false sworn statement is a criminal offence punishable by law. This is often underestimated: the document is not a mere administrative formality, but a statement in which the declarant certifies facts under their own responsibility.
This certificate is not proof of address in the strict sense. An organisation (CAF, health insurer, bank) may accept it as temporary evidence of a change of address, but it often also requires a separate supporting document, such as an energy bill, council tax notice or proof of occupancy for the new home.
We recommend always checking with the recipient organisation whether a sworn statement is sufficient or needs to be accompanied by additional proof. A properly structured moving certificate template can help avoid back-and-forth, but does not remove the need to check in advance.
Required information for a valid moving certificate
The absence of an official form does not mean the content is unrestricted. For a certificate to be accepted, it must include a minimum set of details that clearly identify the declarant, the addresses concerned and the moving dates.
- Full identity of the declarant: surname, first name, date and place of birth, and identity document number (national ID card or passport). Omitting the identification number is a common reason for rejection.
- Departure address (previous residence) and arrival address (new residence), written in full with street number, postcode and town or city.
- Actual moving date or, if not yet known, the planned departure date and move-in date if they differ.
- An explicit sworn statement, for example: “I, the undersigned, [name], solemnly declare that I moved from [old address] to [new address] as of [date].”
- Place and date of signing, followed by the declarant’s handwritten signature.
Including a copy of both sides of the identity document as an attachment strengthens the document’s credibility. Some employers require it as standard when processing a request for moving leave.
Drafting errors that lead to rejection
Three reasons for rejection come up regularly. The first is omitting the phrase “on my honour”, which deprives the document of its status as a formal declaration. The second is an incomplete address (a town or city without a postcode, or no street number). The third is an imprecise date: writing “sometime in October” instead of an exact date makes the certificate unusable for an organisation that needs to record a change of circumstances.
Moving certificate and proof of address: two separate documents
Confusing these two documents causes most administrative delays. The certificate declares a fact; proof of address verifies it.
A sworn statement of moving is a self-declared document. Proof of address, on the other hand, is issued by a third party (an energy supplier, telecoms provider or tax authority) and confirms that the declarant actually lives at the stated address.
In practice, after a recent move, a new tenant or homeowner may not yet have a bill in their name for the new home. This is precisely when a sworn statement is useful: it serves as temporary documentation while they wait to receive their first proof of address.
Documents accepted as proof of address after a move
Once you have moved in, several documents can supplement or replace the original certificate:
- A gas, electricity or water bill issued within the last six months in the declarant’s name and showing the new address.
- A signed tenancy agreement for the new home or proof of ownership.
- A tax notice or certificate of non-taxation showing the current address.
- Home insurance certificate for the new residence.
A certificate of accommodation, sometimes confused with a moving certificate, applies to a different situation: it is written by a third party who confirms that the declarant is staying at their home. It does not replace a moving certificate and serves a different purpose.
Special cases: moving from abroad and municipal certificates
Returning to France after a stay abroad is not subject to the same rules as an ordinary move within the country. A certificate of change of residence issued by a consulate or embassy confirms the transfer of residence to France, but its scope is limited to this specific situation. Presenting it as proof of address in France would be a mistake.
Some municipalities (Cergy, Noisy-le-Grand, among others) offer local certificates of change of residence. We have found that these documents are not standardised nationwide: whether they are accepted depends on the recipient organisation and its internal policy. Before visiting the town hall, it is best to confirm that the organisation concerned recognises this type of certificate.
No town hall is required to issue a moving certificate. Where this service is available, it is offered at the municipality’s discretion. A sworn statement drafted by the declarant therefore remains the most universally usable basic document while they wait for formal proof of address.
The deadline for notifying the main organisations (social security, tax authorities, pension fund) of a change of address is generally one month after the move. Preparing the certificate before moving day and entering the planned date makes it possible to start the process without waiting for the first bills at the new address.
