1. A person or other entity for whom support is being collected pursuant to NRS 31A.025 to 31A.190, inclusive, shall notify the enforcing authority of a change of address within a reasonable time after the change. The notice must be sent by first-class mail or electronically.

The enforcing authority shall notify the income payer to discontinue withholding.
