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 to Do If You Want to Change Your Name or Your Child's Name in Denmark

  • 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.
