When a decision regarding paternity or co-maternity established abroad has been recognized in Norway, it will apply as if it had been established in Norway. It shall then be used in all contexts where paternity or co-maternity is of importance. 

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

If paternity or co-maternity for your child has been established outside of the Nordic countries, you may apply for recognition of the foreign decision in Norway. You may also apply for recognition of foreign decisions on alteration of paternity or acquittal of paternity. 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 was established, e.g. a declaration, court order or administrative decision
  • Documentation of the identity of the parents and the child, e.g. a passport or valid identity card

The decision or other documentation of the estabishment must either be in original and affixed the apostille stamp, or be legalized by the authorities of the country where the documents are issued. Other documentation must either be in original or confirmed copy.  We can return the original documents to you if you ask us to.  Documents in other languages must be translated to Norwegian or English by a state-authorized translator.  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:

  • You and the other parent were married when the child was born. Paternity or co-maternity will follow directly from marriage in most countries. This is called the “pater est” rule.  Paternity or co-maternity is then considered to follow directly from foreign law. 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 order or declaration in one of the Nordic countries (Denmark, Finland, Iceland and Sweden). You must then contact the Norwegian Tax Administration to have the paternity or co-maternity registered in Norway.
