Can I adopt a child in Luxembourg?
Yes, but adoption always goes through a court judgment — and the framework has just been modernised. Luxembourg has two forms: full adoption, which severs the ties with the birth family and is irrevocable, and simple adoption, which keeps those ties while adding rights in the adoptive family. The application is brought before the district court by a lawyer's petition, examined in chambers with the prosecutor, in the sole interest of the child. In principle the adopter is at least 25 and 15 years older than the child. A reform passed by the Chamber of Deputies on 2 April 2025 opens both adoptions to partners and cohabitees, opens full adoption to single people, and makes the consent of a child capable of discernment compulsory. The myth: "only married couples adopt" — false, and beware: some official pages have not yet taken in the whole reform.
📋 The rules
- Two forms: full adoption (irrevocable, it replaces the birth filiation) and simple adoption (it keeps the ties of origin).
- Court decision: the application is made by a lawyer's petition before the district court, in chambers and with the prosecutor present.
- Age conditions: the adopter must be at least 25 (21 for the second member of a couple) and 15 years older than the child, 10 years for a spouse's child.
- Child's interest: the judge chiefly checks that the adoption is in the interest of the child, a condition that prevails over everything else.
- Reform of 2 April 2025: it opens adoption to partners and cohabitees, full adoption to single people, and requires the consent of a child capable of discernment.
🔓 Exceptions
- Adopting a spouse's child: no age condition is required and a 10-year gap is enough; the birth filiation towards that parent remains.
- Single person: full adoption is open to a single person, provided they are neither married, nor partnered, nor cohabiting.
- Official pages lagging: in mid-2025 the justice.lu page still showed the old "under 16" threshold; check the up-to-date Civil Code on Legilux.
⚠️ Penalties & fines
Here the risk is not criminal: it is the judge's refusal and irreversibility. The court dismisses the application if the legal conditions are not met or if the adoption does not serve the child's interest, after an investigation that can take months. Full adoption is irrevocable: once granted, it permanently severs the ties with the birth family, with no way back, which explains the judge's caution. Simple adoption, by contrast, can be revoked on serious grounds, but leaves two families coexisting, with inheritance and maintenance effects to anticipate. Add the uncertainty of the timetable tied to the 2025 reform: until the codified text is settled on Legilux, a file built on an outdated page can be knocked back, and a poorly prepared international adoption risks not being recognised in Luxembourg.

❓ Frequently asked
What is the difference between simple and full adoption?
Full adoption severs all ties with the birth family, is irrevocable and treats the child as one born to the adopters. Simple adoption, by contrast, keeps the birth filiation, adds rights in the adoptive family and can be revoked on serious grounds.
Do you have to be married to adopt in Luxembourg?
No: a single person can adopt, and the reform passed on 2 April 2025 also opens adoption to people in a registered partnership and to cohabiting couples. Adopting the child of a spouse, partner or cohabitee is likewise possible.
What age do you have to be to adopt?
In principle the adopter must be at least 25, reduced to 21 for the second member of a couple, and 15 years older than the child. That gap falls to 10 years for a spouse's child, and the judge may now depart from it for good reasons.
Who decides on the adoption?
It is the district court that rules, seized by a lawyer's petition to the Court, after an investigation in chambers and with the prosecutor present. The judge checks above all that the planned adoption is genuinely in the best interest of the child.
Is the official information on adoption reliable?
It is reliable on the principles, but the 2025 reform was not yet reflected everywhere: in mid-2025 the justice.lu page still mentioned the old under-16 threshold. It is best to check the codified text of the Civil Code on Legilux and confirm the date of entry into force.
