There is a very strict Law on Personal Names in demark that protects children from having a weird name given by their parents, so parents will have to choose from government-approved 7000 names for girls and boys.
However, If parents want to name their child something that isn’t on the list, they will have to get special permission from their local church, and the name is then reviewed by governmental officials.
Creative spellings of more common names are often rejected. The law states that girls and boys must have names that indicate their gender, you can’t use the last name as a first name, and unusual names may be rejected.
About 1,100 names are reviewed each year, 15-20% of the names are rejected. There are also laws in place to protect rare Danish last names.
