Paternity or co-maternity established abroad

Language

Paternity or co-maternity established abroad may be recognised in Norway.

When paternity or co-maternity established abroad has been recognised in Norway, it should be used in all contexts where paternity or co-maternity is of importance.

When is it relevant to apply for recognition of paternity or co-maternity?

If paternity or co-maternity has been established outside the Nordic countries by a declaration, court or administrative decision, the parents may apply for recognition of the foreign decision in Norway.
Foreign decisions on change of paternity or acquittal for paternity may be recognised in the same way.
NAV has created a form, which is located under “Related information”. The application must be submitted to NAV together with:

  • The child’s birth certificate; an international or extended version if available
  • Documentation of how the paternity / co-maternity has been established, e.g. a declaration, judgment or administrative decision
  • Documentation of the identity of the parents and the child, e.g. a passport or valid identity card

Certificates must be original and affixed to the apostille stamp, or be legalized by the authorities of the country where the documents are issued.

If the applicant does not wish to submit original documents, NAV will accept documents stamped with the correct copy of the Norwegian foreign service mission.

NAV submits the decision to the Norwegian Tax Administration for registration if the paternity or the co-motherhood is recognized.

You do not need to apply for recognition when:

  • Paternity or co-maternity follows directly from foreign law. This mainly applies to paternity that follows from the “pater est” rule, i.e., the man who is married to the woman giving birth at the birth of the child is considered the child's father. The parents must contact the Norwegian Tax Administration if the marriage is entered into abroad, and this is not registered in Norway.
  • Paternity or co-maternity has been established by court judgment or declaration in one of the Nordic countries (Denmark, Finland, Iceland and Sweden). The parents must contact the Norwegian Tax Administration to have the paternity or co-maternity registered in Norway.
