Changing your first name is no longer the judicial obstacle course it once was. Since the Modernisation of 21st Century Justice Act, the procedure has been considerably simplified and decriminalised, transferring the authority directly to civil status officers. Whether it is to remedy a disadvantage linked to a ridiculous first name, to formalise long-term usage, or to align your identity with your gender, the process is now carried out at the town hall. Here is the complete and updated guide to successfully changing your first name in 2024.

The principle of the immutability of surnames and first names is a pillar of French civil law, but it includes strictly regulated exceptions. To obtain a change of your first name, you must justify a legitimate interest (intérêt légitime).
The procedure is primarily governed by *Article 60 of the Code civil (French Civil Code)*. This article states that:
> “Any person may request to change their first name. The request is submitted to the civil status officer of the town hall of their place of residence or their place of birth.”
Law No. 2016-1547 of 18 November 2016 on the modernisation of 21st-century justice transferred this jurisdiction from the juge aux affaires familiales (JAF - French family court judge) to the officier d'état civil (civil status officer, i.e., the mayor or their delegated deputies).
Legitimate interest is the cornerstone of your application. The civil status officer has sole discretion to assess the reasons invoked. In 2024, the reasons generally accepted as legitimate are:

For your application to be admissible, you must follow a precise administrative path. Here are the 5 essential steps to successfully complete your application in 2024.
You have a legal option. You can submit your application file:
Note for French citizens born abroad: You must send your request by post to the Service central d'état civil (SCEC - Central Civil Status Service) of the Ministry of Europe and Foreign Affairs, located in Nantes.
You must fill out the official Cerfa form (generally *Cerfa No. 1622301** for adults). This form must be accompanied by several mandatory supporting documents:
1. A full copy of your birth certificate (copie intégrale de l'acte de naissance) dating back less than 3 months (or less than 6 months if issued by a consulate or the SCEC).
2. A valid proof of identity (national identity card, passport, or titre de séjour - French residence permit).
3. A recent proof of address (justificatif de domicile), such as an electricity bill, non-handwritten rent receipt, or tax notice. If you are being housed by someone else, provide an accommodation certificate (attestation d'hébergement), along with the host's ID and proof of address.
4. All documents proving your legitimate interest (see below).
This is the most important part of your application. You must provide material and tangible evidence. For example:
The application must be submitted in person. Many town halls now require you to book a prior appointment for this procedure. Upon submission, the civil status officer will check that the file is complete and may ask you a few questions to understand your motivations.
If the civil status officer deems the request legitimate, they will approve the change. They will then proceed to update your birth certificate. Once your birth certificate is modified, other civil status records concerning you (marriage certificate, birth certificates of your children or spouse) will also be updated automatically.

The request to change a minor's first name must be submitted by their legal representatives (parents or guardian).
A foreigner legally residing in France can request a change of first name at the town hall, provided that their foreign birth certificate is held by a French authority (for example, if they have refugee or stateless status with the OFPRA - French Office for the Protection of Refugees and Stateless Persons).
For other foreign nationals, the request must in principle be made to the consular authorities of their country of origin. However, if the foreigner has acquired French nationality, they can request the Frenchification of their first name within one year following the acquisition of nationality.

The removal of this procedure from the court system has drastically reduced costs and, to a lesser extent, processing times.

Although the procedure at the town hall is free, changing your identity can generate indirect costs linked to updating your daily life.
Camille, 28, has used the first name "Camille" daily since her teenage years, while her birth certificate states "Jean-Marc". She submits her request to the town hall of Lyon.
Youssef, recently naturalised as a French citizen, wishes to Frenchify his first name to "Joseph" to facilitate his professional endeavors. He submits his request to the town hall of his home in Bordeaux.

To maximise your chances of having your application accepted on the first attempt, avoid these common mistakes:
---
If the civil status officer believes that your request is not based on a legitimate interest, they cannot reject your application directly. They must *refer the matter to the procureur de la République*** of the competent judicial court and inform you of this action.
The prosecutor then has two options:
1. They approve your request: The civil status officer then records the change of first name.
2. They oppose the change: You will receive a reasoned notification of refusal.
In the event of a refusal by the public prosecutor, you have a right of appeal. You must then *refer the matter to the juge aux affaires familiales (JAF) of the judicial court. For this judicial phase, representation by a lawyer is mandatory*. The judge will re-examine your file and make a final ruling.

In theory, the choice of first name is free. However, the civil status officer can oppose a first name if they believe it is contrary to the interests of the person (a ridiculous or vulgar name, or one creating unwanted gender confusion) or if it harms the rights of third parties (usurping a famous surname).
It is possible to change the order of your first names, delete some, add new ones, or modify the spelling of an existing first name. There is no strict limit set by law, but each modification or addition must be justified by a distinct legitimate interest.
Yes, this is a practical obligation. Once you have obtained your new birth certificate, you must inform the Social Security (CPAM), the family allowance fund (CAF), the tax office, your bank, your employer, your insurers, and utility providers. You will need to provide them with a copy of your new birth certificate or your new identity document.
The law does not prohibit making multiple requests during your lifetime. However, the legitimate interest will be examined with increased scrutiny by the civil status officer during a second request, in order to prevent abuse or instability of civil status records.
