If a court or an administrative entity orders past support that covers a period in which the obligee was on cash assistance, the amount for that period is assigned to the state and the Title IV-D Agency shall distribute collections in accordance with A.R.S. § 46-408 and disburse support in accordance with this Article. If a child covered by the order was receiving Title IV-E foster care maintenance payments for any of the period covered by the judgment, the amount for that period is assigned to the state and collections shall be distributed in accordance with R6-7-608. A past support judgment ordered on and after September 26, 2008 does not accrue interest.
