North Dakota Century Code Title 14. Domestic Relations and Persons § 14-15-20. Adoption and legitimation by conduct

Notwithstanding the other provisions of this chapter, the biological father of an illegitimate minor adopts and legitimates a minor by publicly acknowledging the minor as that man's child, receiving the minor into that man's home, with the consent of that man's wife, if that man is married, and otherwise treating the minor as if the minor were legitimate. Thereafter, the minor is deemed the legitimate child of the father for all purposes from the time of birth of the minor, the same as if the adoption had been finally decreed pursuant to this chapter.
