Citizenship declaration for a child born abroad whose parent is a Finnish citizen

Submit this declaration to apply for Finnish citizenship for a child under 18 years of age if:

  • the child is born outside marriage in a country other than Finland and only the child’s father is a Finnish citizen, or
  • the child is born in a country other than Finland and has 2 mothers and only the non-birth mother is a Finnish citizen.

You can submit a citizenship declaration for a child only if you have custody of the child or have been appointed as the child's legal guardian.

If you are the child’s parent and a Finnish citizen, your paternity or maternity must be established abroad before you submit the declaration.

A child will automatically become a Finnish citizen if 1 of the child’s parents is a Finnish citizen and the parents have married each other after the child was born. In such a case, a citizenship declaration for the child is not required. Instead, the Digital and Population Data Services Agency will enter the child’s Finnish citizenship in the Population Information System of Finland. 

You will find the declaration form at the foot of this page. Please read the instructions on this page first before filling in the form.
