Nev. Sup. Ct. R. 251
In all cases affecting the custody or visitation of minor children including, but not limited to actions seeking termination of parental rights, except cases arising in the juvenile courts, the district courts must resolve the issues affecting the custody or visitation of the child or children within six months of the date that such issues are contested by the filing of a responsive pleading that contests the custody or visitation issues. Extraordinary cases that present unforeseeable circumstances may be subject to extensions of time beyond the six-month period only upon entry by the court of specific findings of fact regarding the circumstances that justify the extension of time. If an appeal is taken to the Supreme Court from an order affecting the custody of minor children, the Supreme Court shall expedite its decision of the appeal.
