Denmark's Rules for Naming Your Baby Explained

Parents in Denmark have six months to name their newborn child. You can register the name on borger.dk. You can also name your child through a christening in a folk church. If you miss the six-month deadline, the child takes the mother's surname. Parents must select a first name or face financial fines. A popular myth claims unnamed babies receive royal names like Frederik. That myth is false.

Denmark enforces strict rules on first names. First names must come from an approved list managed by the Agency of Family Law. Boys cannot receive girls' names and girls cannot receive boys' names. Parents can apply to add new names to the approved list. Authorities review applications to ensure names are suitable. For instance, inappropriate words or object names like Fridge will be rejected.

Middle names offer more flexibility under Danish law. A girl may hold a traditional boy's middle name. Middle names appear as a second first name on Danish passports. However, Denmark allows only one official surname per person. Free surnames belong to more than 2000 people. Surnames with fewer than 2000 holders are protected by law.

Parents may use a protected surname under specific legal conditions. For example, family lineage or written permission from existing holders can qualify. Foreign surnames require prior official approval before registration. Parents can also choose a hyphenated double-barreled surname. Matching these rules with foreign naming laws requires careful planning.
