Any adopted person who is 18 years of age or older is entitled to information on his or her biological parents. Such information can be obtained by contacting the Ministry or the County Governor that granted the adoption.

Pursuant to the Norwegian Adoption Act dated February 28, 1986, only the relevant County Governor or Ministry is authorized to provide information on biological parents to an adopted person.

In the period from 1917 through 1933, adoptions were primarily granted by the Norwegian Ministry of Justice, and subsequently by the County Governors. The relevant Ministry or County Governor may have deposited the relevant archival material with either the National Archives or the local regional state archive. If an adopted person wishes to obtain information on his or her biological parents, the individual should contact the relevant Ministry or County Governor. Said entities will gather any pertinent information in the holdings of the National Archives or relevant regional state archive and forward such data to the petitioner.

All adoptions that have taken place from 1917 to the present are recorded in the Central Adoption Registry. This registry is currently maintained by Norwegian Directorate for Children, Youth and Family Affairs (Bufetat).Further information can be obtained by submitting a request to:
