Can I change the gender marker on my civil status in Luxembourg?
Yes — and since 2018 it is a simple administrative step, free of charge, with no surgery or medical certificate. The law of 10 August 2018 replaced the old court procedure with an application based on self-determination. The text says it in black and white: not having undergone medical treatment, surgery or sterilisation cannot justify a refusal. The application goes to the Minister of Justice (in writing, through a lawyer, or online on MyGuichet.lu) for any adult with legal capacity; it is also open to minors from age 5 (with the parents' agreement, and the consent of a child aged 12 or over). You must show, through a body of facts, that the recorded sex does not match the lived reality. The myth: "you need surgery or medical proof and a court case" — false since 2018: no operation, no certificate, no judge for a capable adult; the decision is a simple ministerial order.
📋 The rules
- Law of 10 August 2018: changing the gender marker is an administrative step, based on self-determination.
- No surgery or certificate: the absence of medical treatment, surgery or sterilisation cannot justify a refusal.
- Application to the Minister of Justice: in writing, through a lawyer or online on MyGuichet.lu; the procedure is free.
- Body of facts: you must show, through a set of elements, that the recorded sex does not match the lived gender.
- Decision by order: the minister grants or refuses by ministerial order; a refusal is challenged before the administrative court.
🔓 Exceptions
- Minors: a minor aged 5 or over applies to the ministry; below that, to the district court; a child of 12 or over must consent.
- Protected adult: an adult under guardianship or curatorship goes through the district court, not the minister.
- Spouse or partner: a married or partnered person must inform their partner beforehand, by a bailiff's writ.
⚠️ Penalties & fines
Here there is no criminal sanction: the risks are refusal, annulment and the administrative burden. The minister can refuse if the body of facts is judged insufficient, and can annul by order a change obtained through false statements, concealment of important facts or fraud, after inviting the person to explain. A refusal is challenged by an administrative appeal and then before the administrative court, within 3 months. Once the change is granted, it is not over: you must, on your own initiative, have your passport, identity card, driving licence and social-security card redone, on presentation of the new birth certificate and the order. Note too: a child conceived after the change has filiation established on the biological sex, and the tie with children already born is unchanged — effects to know before starting.

❓ Frequently asked
Do you need surgery to change the gender marker?
No, the law of 10 August 2018 expressly forbids requiring surgery, medical treatment or sterilisation as a condition. The change rests on the person's self-determination, who need only show through a set of facts that the recorded sex does not match their reality.
Who do you send the application to?
For an adult with legal capacity, the application goes to the Minister of Justice, in writing, through a lawyer or online via MyGuichet.lu. Adults under guardianship or curatorship, for their part, must go through the competent district court.
Is the procedure free?
Yes, the procedure for changing the gender marker and first names is entirely free in Luxembourg. The only possible costs are those of a lawyer, if you choose to use one, and the renewal of your identity documents once the change is granted.
Can a minor change their gender marker?
Yes, a minor aged at least five applies to the Ministry of Justice, with the agreement of the holders of parental authority. Below five, it is the district court that decides, and from age twelve the child must personally give their consent.
Does the change affect the tie with my children?
No, changing a parent's gender marker changes nothing in the filiation with children already born or in the rights that flow from it. However, a child conceived or born after the change will have their filiation established on the basis of the parent's biological sex.
