Citizenship by birth

If the parents are married, and either the mother or the father is Danish, the child is automatically a Danish citizen by birth no matter where the child is born.

If the parents are unmarried, the child automatically acquires Danish citizenship if the mother is Danish. If only the father is Danish, the child automatically acquires Danish citizenship only if it is born in Denmark on 1 February 1999 or later.

Citizenship by marriage after birth

A child, who has not acquired Danish citizenship by birth, can later acquire citizenship. If the child for example is born outside Denmark, and only the father is Danish, the child can get Danish citizenship if the parents marry before the child’s 18th birthday.

Citizenship by adoption

Adopted children under the age of 12 automatically acquire Danish citizenship if they are adopted by either one Danish citizen or a married couple where at least one of the parties is Danish.

Adopted children above the age of 12 can only acquire Danish citizenship by application. This can first take place when the child has been living in Denmark for at least two years.
