(1) Sections 17 and 18, chapter 171, Laws of 1979 ex. sess. (RCW 74.20.320 and 74.20A.270), provide that a custodian of children or other person who receives support money which money was paid, in whole or in part, toward a support obligation under 42 U.S.C. 602 (a)(26)(A), sections 17 and 22, chapter 171, Laws of 1979 ex. sess., or RCW 74.20A.030 must remit that money to the division of child support (DCS) within eight days of receipt, and is indebted to the department for this amount of money.

DCS may use the collection procedures of chapter 74.20A RCW to collect this assigned delinquency, to satisfy a debt owed under subsection (1) of this section.

(5) DCS must give the CP or other person an account of actions taken under subsections (2) or (3) of this section.
