Name Change
Written in plain language for general understanding. This is educational content, not legal advice. Based on Danish Acts of Parliament (love), executive orders (bekendtgørelser), and official government guidance.
Danish National Law
What is this right?
Denmark's Name Act governs first names, middle names, and surnames:
- Free choice of surname on marriage: Either spouse can take the other's surname, keep their own, or use a hyphenated combination.
- General name change: You can change your first name or surname through Familieretshuset — some changes are automatic (e.g., taking a spouse's name), others require approval.
- Protected surnames: Surnames used by fewer than 2,000 people in Denmark are protected — you cannot adopt them without a family connection.
- Children's names: Parents must register a child's name within 6 months of birth. First names must be from an approved list or individually approved.
When does it apply?
- You are getting married or divorced and want to change your name.
- You want to change your first name, middle name, or surname for any reason.
- You need to register a newborn's name.
What should you do?
- Apply through Familieretshuset or the church (folkekirken) if it relates to a birth registration.
- For marriage-related changes, the name change can be processed as part of the marriage or divorce application.
- If you want an unusual first name, check whether it is on the approved names list — if not, you must apply for individual approval.
What should you NOT do?
- Don't miss the 6-month deadline for naming a newborn — the church or municipality will follow up.
- Don't assume any name is available — protected surnames and unapproved first names require special permission.
- Don't use a changed name in official documents before it is registered — the change is effective from the date of registration.
