N.D. Cent. Code § 14-20-42: (607) Limitation - Child having presumed father

1.Except as otherwise provided in subsection 2, a proceeding brought by a presumed father, the mother, or another individual to adjudicate the parentage of a child having a presumed father must be commenced not later than two years after the birth of the child.

2.A proceeding seeking to disprove the father-child relationship between a child and the child's presumed father may be maintained at any time if the court determines that:

a.The presumed father and the mother of the child neither cohabited nor engaged in sexual intercourse with each other during the probable time of conception; and

b.The presumed father never openly held out the child as his own.

3.For purposes of this section and section 14-20-43, an action to establish support for a child is a proceeding to adjudicate parentage if the child's presumed father raises nonpaternity as a defense to the action.
