Nevada Revised Statutes Title 11. Domestic Relations § 130.614. Notice to issuing tribunal of modification

Within 90 days after the issuance of a modified child-support order, the party obtaining the modification shall file a certified copy of the order with the issuing tribunal that had continuing and exclusive jurisdiction over the earlier order and in each tribunal in which the party knows the earlier order has been registered. A party who obtains the order and fails to file a certified copy is subject to appropriate sanctions by a tribunal in which the issue of failure to file arises. The failure to file does not affect the validity or enforceability of the modified order of the new tribunal having continuing and exclusive jurisdiction.
