NRS 126.101: Parties.

1. If the court determines that it is necessary for the child to be made a party to the action, the court may make the child a party to the action. If the child is a minor and the court determines that it is necessary to appoint a guardian ad litem to represent the child, the court may appoint a guardian ad litem for the child. The child’s mother or father may not represent the child as guardian or otherwise.

2. The natural mother and a man presumed to be the father under NRS 126.051 must be made parties, but if more than one man is presumed to be the natural father, only a man presumed pursuant to subsection 2 or 3 of NRS 126.051 is an indispensable party. Any other presumed or alleged father may be made a party.

3. The court may align the parties.
