How to Change Your Name in France (2026): Minors, Parental Consent, Civil‑status Filings & Cross‑border Documents

Understanding how to change your name in France has become significantly more straightforward since the landmark reform that took effect on 1 July 2022, which introduced a simplified administrative route alongside the traditional decree procedure. Whether you are an adult seeking to adopt an ancestor’s surname, a parent filing a joint declaration for a minor child, or a dual national navigating apostille requirements for foreign documents, the process now follows clearly defined channels through the mairie (town hall), the Ministry of Justice, or, for persons born abroad, OFPRA.

This guide consolidates every route, required document, timeline and practical trap into a single resource, updated as of July 2026, to help French nationals, residents and cross‑border families file with confidence and avoid costly delays.

Quick Answer, Can You Change Your Name in France?

Yes. French law permits both first‑name (prénom) and surname (nom de famille) changes, but each follows a different procedure and is handled by a different authority.

• First‑name change. Filed at the civil status office France, specifically the mairie of your place of birth or residence. The registrar (officier de l’état civil) has the authority to approve the request directly, provided you demonstrate a legitimate interest (intérêt légitime).
• Surname change by simplified procedure. Since the 2022 reform, any adult may request, once in their lifetime, to bear the surname of the parent whose name they do not currently carry, or to combine both parents’ names. This is done by simple declaration at the mairie.
• Surname change by decree. For all other surname changes, such as adopting a different family name for reasons of public interest, ridiculousness, or foreign‑sounding character, the applicant must seek a name change decree France from the Ministry of Justice (Ministère de la Justice).

Eligibility checklist at a glance:

• You must be a French national (or, for first‑name changes, have your civil status registered in France).
• You need supporting documents: birth certificate extract, proof of identity, proof of domicile, and a written justification for the change.
• Filing takes place at the mairie of your birth or residence (first name or simplified surname), or with the Garde des Sceaux at the Ministry of Justice (decree route).

Which Route Applies to You, Quick Decision Guide

The correct procedure depends on whether you are changing a first name or a surname, whether you are an adult or a minor, and whether the change relates to marriage, adoption, or another cause. The following decision points will direct you to the right section of this guide.

• Changing your first name? → Route A (mairie procedure). If you were born abroad and your civil status is held by OFPRA, the request goes to OFPRA instead.
• Adding or substituting a parent’s surname (simplified procedure)? → Route B‑1 (mairie declaration under the 2022 reform). Adults only; minors require joint parental declaration (see the minors section below).
• Changing your surname for another legitimate reason (e.g., name is pejorative, historically linked to infamy)? → Route B‑2 (Ministry of Justice decree).
• Using a spouse’s name after marriage? → No formal civil‑status change is required. You may use your spouse’s name as a nom d’usage (usage name), but your birth surname remains unchanged on civil records. To change the name on French passport documents, see the identity‑documents section.
• Adoption‑related name change? → See the adoption section; the court judgment itself may alter the child’s surname.
• Non‑citizen or foreign resident? → French name‑change procedures generally apply only to French nationals or persons whose civil status is registered in France. Non‑citizens should consult the authorities of their country of nationality.

Route A, First Name (Prénom) Change via Mairie or OFPRA

Who Can Apply

Any person whose birth is registered in France, or whose civil status has been reconstituted by OFPRA, may request a first‑name change. Adults apply in their own right. Minors must be represented by their legal representative(s), and any minor aged thirteen or over must give personal consent to the change.

Required Documents

• Valid proof of identity, national identity card or passport.
• Full copy (copie intégrale) of the birth certificate, dated less than three months before filing.
• Proof of domicile, utility bill or tax notice.
• Written statement of reasons, a letter explaining why the change is sought and demonstrating a legitimate interest (e.g., first name is a source of ridicule, does not reflect gender identity, is excessively difficult to use in daily life).
• Supporting evidence, any documents that corroborate the justification (medical certificates, attestations, evidence of long‑standing use of the desired name).

Process and Timeline

The application is submitted to the civil status office France at the mairie of your place of birth or your place of residence. The officier de l’état civil reviews the file and either approves the change or refers it to the local procureur de la République (public prosecutor) if the legitimate interest appears doubtful. If the prosecutor opposes, the applicant may appeal to the tribunal judiciaire.

Processing times vary, but straightforward cases are typically resolved within one to three months at the mairie. Contested cases referred to the tribunal can take six months or longer. For applicants whose birth certificate is held by OFPRA, including refugees and stateless persons, the first‑name change request is addressed directly to OFPRA in Fontenay‑sous‑Bois, and the timeline is generally similar.

Important distinction: this route covers first‑name changes only. If you need to change your surname, you must use the simplified declaration or the decree procedure described below.

Route B, Surname Change (Nom de Famille) by Decree or Simplified Declaration

The 2022 Reform: Simplified Administrative Route

The reform that entered into force on 1 July 2022 created a new pathway allowing any adult to change their surname by simple declaration at the mairie, without needing a ministerial decree, provided the request falls within a specific scope: adopting the surname of the parent whose name the applicant does not carry, or combining both parents’ surnames in the order of their choice. Each person may use this simplified route only once in their lifetime. This reform significantly reduced the administrative burden for many applicants who previously had to petition the Ministry of Justice.

When the Decree Route Is Still Required

The traditional name change decree France route remains necessary when the desired surname does not fall within the simplified‑declaration scope, for example, when the applicant wishes to:

• Adopt a surname that is neither parent’s name (e.g., a grandparent’s surname to prevent extinction of a family line).
• Change a surname that is pejorative, ridiculing, or historically associated with infamy.
• Francise a foreign‑sounding surname.
• Address confusion created by homonymy with a public figure or convicted person.

The application is addressed to the Garde des Sceaux (Minister of Justice) and must include a detailed justification, a full birth certificate, proof of nationality, and any evidence supporting the legitimate interest. If approved, the change is enacted by a decree published in the Journal Officiel. Third parties have a two‑month window from publication to contest the decree before the Conseil d’État.

Timeline and Outcomes

The decree procedure is substantially longer than the simplified route. Industry observers report that the Ministry of Justice typically takes between twelve and eighteen months to process a decree application, though complex cases may take longer. Once published, the decree takes effect after the two‑month opposition period.

Costs, How Much Does a Name Change Cost in France?

The administrative filing for a first‑name change or a simplified surname declaration at the mairie is free of charge. There are no government fees for the decree route itself, although applicants may incur costs for certified copies of civil‑status documents and, if instructing a lawyer, professional fees. After the name change is finalised, updating identity documents carries standard renewal costs: passport and identity card renewal fees are set by ANTS and can be verified on the ANTS platform.

If you need to change your name after marriage France, the nom d’usage can usually be added to identity documents at no extra charge during a standard renewal, but a dedicated early renewal before the card’s expiry date may attract the applicable replacement fee.

Minors and Joint Declaration, Parental Consent and the Choice of a Child’s Surname

When a Minor’s Name Can Be Changed

A minor’s surname may be changed through the simplified declaration procedure, but it requires the involvement of both parents. The choice of a child’s surname by father and mother is a joint parental right, and any change must serve the child’s best interests. Minors aged thirteen or over must personally consent to the change.

Joint Declaration Procedure, Step by Step

When both parents agree, the procedure is as follows:

1. Both parents attend the mairie, either the child’s place of birth or the parents’ place of residence.
2. File a joint declaration, a written document signed by both parents, stating the desired surname (the other parent’s name, or a combination of both names in the chosen order).
3. Provide required documents, see the checklist table below.
4. The officier de l’état civil records the change, the child’s birth certificate is annotated accordingly.
5. The child’s consent is obtained, if aged thirteen or over, the child must sign a consent form.

Cross‑Border Issues When One Parent Is Foreign

When one parent resides abroad or holds a foreign nationality, collecting valid consent can be the most complex step. The foreign parent’s consent document must be:

• Authenticated, either apostilled (if the country is a signatory to the Hague Apostille Convention) or legalised by the French consulate in the parent’s country of residence.
• Translated, a certified French translation by a traducteur assermenté (sworn translator) is required.
• Dated and signed, the document must clearly identify the child and state the parent’s agreement to the specific name change.

If one parent refuses consent, the other parent may petition the juge aux affaires familiales (family judge) to authorise the name change, provided it is in the child’s best interest.

Required Documents for a Minor’s Name Change

Adoption and Name Effects, Simple Adoption vs Full (Plenary) Adoption in France

Simple Adoption, Legal Effect on Name

Under simple adoption France rules, the adopted person generally adds the adopter’s surname to their existing name, unless the court decides otherwise. The child retains legal ties, including inheritance rights, with the birth family. Parental authority may coexist between the adoptive parent and the birth parent(s), depending on the court order. The judge may authorise a full substitution of name in specific circumstances, but this is not the default.

Full (Plenary) Adoption, Complete Substitution of Filiation

Full adoption France creates a complete and irrevocable new filiation. The child’s birth certificate is redrawn as if they had been born to the adoptive parent(s). The birth surname is replaced by the adoptive parent’s surname (or a combination, at the parents’ choice). All legal ties with the birth family are severed, and the adoptive parent(s) exercise exclusive parental authority.

Procedural Requirements and Consent

Both types of adoption require a court judgment from the tribunal judiciaire. Consent of the birth parents (or the family council) is required, as is the consent of the child if aged thirteen or over. The court evaluates whether the adoption serves the child’s best interests before issuing a judgment that takes effect on the civil register.

Updating Identity Documents and Travel Papers After a Name Change

How to Change Name on French Passport and National ID via ANTS

Once the name change is officially recorded on the civil register, the next step is to update identity documents. All applications for a new passport or national identity card (carte nationale d’identité) are submitted through the ANTS platform (Agence Nationale des Titres Sécurisés). You will need:

• Updated birth certificate, a copie intégrale or extract reflecting the new name, dated less than three months.
• Current identity document, the existing passport or ID card being replaced.
• Passport‑format photograph, compliant with ANTS requirements.
• Proof of domicile.
• Revenue stamps (timbres fiscaux), required for passport renewal; the amount is set by current regulations and can be purchased online via the timbres.finances.gouv.fr portal.

If You Live Abroad, Consular Procedure

French nationals residing outside France should contact their local French consulate. The consulate can process passport and identity card renewals and will coordinate with the Service Central d’État Civil (SCEC) in Nantes for updated civil‑status extracts. Apostille and translation requirements for supporting foreign documents apply as described in the cross‑border section below.

Notification Checklist, Who Else to Inform

After receiving new identity documents, update your records with the following bodies in the order suggested:

1. Employer or professional body (payroll and social contributions)
2. Tax authorities (impôts, update via impots.gouv.fr)
3. Social security / health insurance (CPAM or MSA)
4. Bank(s) and financial institutions
5. Driving licence authority (ANTS, separate application for permis de conduire update)
6. Utility providers, insurers, telecommunications
7. Educational institutions (if applicable)

Cross‑Border Issues: Foreign Documents, Apostille, Consular Consent and Translations

How to Validate a Foreign Parent’s Consent

When a parent or guardian is located outside France, any document they sign, whether a consent form, joint declaration, or statutory declaration, must be authenticated for use in France. If the issuing country is a member of the Hague Apostille Convention, an apostille from the competent authority of that country suffices. If the country is not a member, the document must be legalised by the French embassy or consulate in that country. In all cases, a certified French translation by a sworn translator is mandatory.

How French Civil Status Handles Foreign Judgments

A name change granted abroad (for example, by a foreign court after adoption or naturalisation) is not automatically recognised in France. The foreign judgment or civil‑status record must be transcribed into the French civil register via the SCEC in Nantes or, for births originally recorded by OFPRA, through OFPRA’s civil‑status division. The transcription process requires submission of the foreign act, its apostille or legalisation, and a certified translation.

Practical note for dual nationals: if you are a French–foreign dual national, a name change performed under the law of your other nationality does not automatically modify your French civil records. You must request transcription or, if the French authorities refuse to recognise the foreign change, pursue a separate French procedure.

Practical Timelines, Common Rejections and How to Avoid Delays

Timelines vary by route. First‑name changes at the mairie generally take one to three months. The simplified surname declaration under the 2022 reform can be processed within a few weeks, provided all documents are in order. The ministerial decree route for other surname changes commonly takes twelve to eighteen months.

The most frequent causes for rejection or delay include:

• Incomplete file, missing birth certificate, expired documents, or absent proof of legitimate interest.
• Missing parental consent, especially for minors when one parent has not signed or the foreign consent is not properly apostilled.
• Poor‑quality translations, translations must be produced by a traducteur assermenté registered with a French Court of Appeal; informal translations are rejected.
• Insufficient justification, particularly for the decree route, where the applicant must demonstrate a concrete and personal legitimate interest.

To minimise delays, compile all documents before filing, verify that every foreign document carries its apostille or legalisation, and use a sworn translator. Consider consulting a family‑law practitioner before submission if your case involves contested parental consent, cross‑border elements, or adoption‑linked complications.

When to Instruct a Lawyer

While straightforward name changes can be handled without legal representation, professional guidance becomes essential in several situations: when one parent opposes the change and court proceedings are required; when foreign documents are difficult to authenticate; when the name change is linked to adoption and the court judgment must specifically address naming; or when the decree procedure involves a complex justification (e.g., public‑figure homonymy). A family‑law practitioner experienced in French civil‑status matters can navigate these procedural obstacles, draft submissions to the Ministry of Justice, and represent applicants before the tribunal judiciaire or family judge.
