Either party may request the IV-D agency to provide the service of seeking the modification of a support order. Applicable fees will be charged to the requesting party in compliance with 8.50.125.10 NMAC. The IV-D agency may seek a modification if the non-custodial parent will be incarcerated for more than 180 calendar days. The IV-D agency will not review a support order for modification without request by a party, unless the custodial party is currently receiving public assistance. In accordance with federal and state laws, a modification of a support order is retroactive only to the time period that a petition or motion was filed with a court and was pending a decision.
