Administrative steps to change a name or first name
Changing a name or first name in France follows a strict and regulated procedure as outlined by the Civil Code. The reasons why a person may wish to change their name or first name are varied. They may be related to personal motivations, such as the desire to have a more French-sounding name, a dislike for the current name, or the wish to honor an ancestor.

First of all, it is appropriate to differentiate between changing a first name, which is often simpler, and changing a name, which usually requires more in-depth justification.
Steps to change a first name
Changing a first name falls under the jurisdiction of the civil status officer. To initiate this process, one must submit a request to their local town hall or place of birth. Here are the steps to follow:

- Write a motivation letter explaining the reason for the first name change.
- Attach to this letter supporting documents, such as a complete copy of the birth certificate and an identity document.
- The complete file is then sent to the public prosecutor for review. If the prosecutor deems the request legitimate and that it does not infringe on the rights of third parties, they authorize the change of first name.
Procedures to change a name
Changing a name is a longer and more complex procedure, requiring a request to the Ministry of Justice. French legislation allows for a name change for legitimate reasons, such as a difficult name to bear or the desire for a family name unity.
The main steps include:
- Write a request explaining the reason for the name change.
- Publish the name change request in the Official Journal and in a legal announcements newspaper to inform the public of this intention.
- Send the publication notices and the request to the Keeper of the Seals.
- The review of the file by the Chancellery can take several months. If the response is favorable, a decree is published in the Official Journal. This decree officially authorizes the name change.

Documents required to change a name or first name
Preparing a comprehensive file is crucial for changing a name or first name. The required documents vary slightly depending on whether it is a name or first name change, but several documents are invariably necessary.
The birth certificate
The birth certificate is at the core of the documents required for any name or first name change. This document, which officially establishes the person’s identity, must be presented in the form of a complete copy, meaning a full copy with all marginal notes. Without this certificate, the file cannot be considered.
Other essential documents
In addition to the birth certificate, here is a list of other commonly requested documents:
- A valid identity document (national identity card, passport).
- A recent proof of residence (EDF bill, rent receipt, etc.).
- The motivation letter detailing the reasons for the name or first name change.
- Legal publications (only for name changes).
Note: In some cases, additional documents may be required, such as medical certificates or testimonies to support the request.
From childhood to adulthood: specifics for minors and adults
The procedure for changing a name or first name also varies depending on the age of the applicant. For minors, the consent of the parents or legal guardian is mandatory. In contrast, for an adult, an individual request is sufficient.
For minors
Parents or the legal guardian must initiate the process on behalf of the minor. The consent of both parents is necessary, except in exceptional cases such as the loss of parental authority of one parent.
The procedure includes the following steps:
- Write a joint request signed by both parents or the legal guardian.
- Attach the usual supporting documents (birth certificate, identity documents of the parents).
- Submit the file at the town hall or to the Ministry of Justice, depending on whether the request concerns the first name or surname.
- In case of disagreement between the parents, the family court judge may be called upon to decide.
For adults
An adult can freely decide to change their name or first name while respecting the legal procedures. The process is carried out individually and follows the previously described steps.
It is essential to prepare the file well and provide all supporting documents in a timely manner to avoid any delays or refusals from the relevant administrations.
Precautions and impacts of changing a name or first name
Changing a name or first name can have significant repercussions on daily and professional life. Therefore, it is wise to carefully consider the implications of this process before proceeding.
Administrative and legal impacts
Once the name or first name change is made, it is imperative to update all identity and administrative documents. This includes:
- The national identity card and passport.
- The driver’s license.
- Property titles and other notarial acts.
- Bank accounts and credit cards.
You will also need to inform:
- Employers.
- Health and social security establishments.
- Schools and universities.
Personal and social consequences
Beyond the administrative aspects, changing a name or first name can influence self-perception and the perception of others. Moderation is necessary. Share this decision with your family and close friends to gain their support.
