§ 580-315 Nonparentage as defense

This law says that if a court has already legally decided someone is a child's parent, that person cannot later try to argue they are not the parent to get out of a support case. Once parentage has been established through a legal process, that decision stands.

This matters because child support cases often depend on who the legal parents are. Without this rule, someone could keep bringing up the same question over and over, even after a judge already settled it. The law stops people from reopening that issue just to avoid paying support or fulfilling other parental duties.

In short, if your parentage has already been legally decided, you cannot use "I'm not the parent" as a defense in a later support case. That question is considered closed.
