You never use your registered name and everyone knows you by another. Or your surname causes ridicule, or endless trouble to pronounce. In those situations a forename or surname can be changed by court order.
Article 27 of the Civil Code provides that a change of name may be sought from the judge on good cause. So the process is judicial, not administrative: you do not apply to the registry to change a name; you bring proceedings.
What Counts as Good Cause
The Act does not define it, leaving the assessment to the judge. The grounds accepted in practice:
- The name is not used in fact: the person is known by a different name in their community, at work and socially. This is the ground most often accepted.
- A name that is ridiculous, wounding or carries a negative association.
- Difficulty of pronunciation or spelling causing constant confusion.
- Confusion with others of the same name — particularly in enforcement, criminal record or bank records.
- Religious or cultural reasons, a change of religion or of nationality.
- A change in family ties: adoption, a judicial declaration of paternity, or correction of parentage.
Simply disliking the name, or fashion, is usually not enough. The request must also be made in good faith: proceedings brought to escape creditors, to distance oneself from a criminal record or to conceal identity are dismissed.
Where the Claim Is Brought, and Against Whom
The court is the civil court of first instance, and the venue is the claimant's place of residence.
The population registry is named as defendant. That is mandatory: a claim brought without it is dismissed for want of a proper defendant. Once the judgment is final, the registry makes the correction.
The court usually requires: the population register extract, the criminal record, proof of residence and the documents supporting the request. Witness evidence is decisive in most files — especially where the ground is being known by another name.
The judgment must become final. The register is not corrected without the certificate that it is final, so either the appeal period must expire or the parties must waive the right to appeal.
What Is Different About Surnames
Two points need care with surnames.
First, the effect: a change of forename concerns only the claimant, while a change of surname as a rule extends to the spouse and minor children. So the claim should set out the family circumstances.
Second, the surname acquired by marriage is a separate subject and not the business of these proceedings. A married woman's wish to use her own surname alone rests on a different legal basis.
On divorce a woman as a rule takes back the surname she had before the marriage. Continuing to use the former husband's surname, where the conditions are met, is a separate application under Article 173.
After the Judgment
Once the judgment is final and the register corrected, the work is not over. Every record tied to the old name has to be updated:
- identity card, passport and driving licence
- land registry and vehicle registration records
- bank accounts, loans and credit cards
- social security and tax records, and the personnel file at work
- diplomas and educational certificates
- pending court and enforcement files
That last point matters: failing to notify a change of name in a pending case or enforcement file causes problems with service and can cost you a right.
A change of name does not end your existing legal relationships: debts, contracts and the criminal record all continue. Only the name changes.
The register is corrected only on a judgment carrying the certificate that it is final. Do not apply for a new identity card as soon as the decision is given: obtain that certificate first, then go to the registry.
Frequently Asked Questions
Can I change my name at the registry?
No. A change of name requires a court order on good cause; only spelling and letter corrections are dealt with administratively.
Which court, and against whom?
The civil court of first instance for your place of residence, with the population registry as defendant. Without that defendant the claim fails.
What is the strongest ground?
Being known by a different name in fact — supported by witnesses and by documents showing the name you actually use.
Does a surname change affect my family?
Yes. As a rule a change of surname extends to the spouse and minor children, so set out the family circumstances in the claim.
Do my debts disappear with my old name?
No. Debts, contracts and the criminal record continue unchanged; only the name changes.
