(1) If the department is providing or has provided cash assistance to the family, parties to a court order must give the division of child support (DCS) twenty calendar days prior notice of the entry of any final order and five days prior notice of the entry of any temporary order in any proceeding involving child support or maintenance, because the department has a financial interest based on an assignment of support rights under RCW 74.20.330 or the state has a subrogated interest under RCW 74.20A.030.

(2) Either party may serve notice on DCS, by personal service on, or mailing by any form of mail requiring a return receipt to, the office of the attorney general.

(3) If you don't give sufficient notice before entering the support order, DCS may ask the prosecuting attorney or attorney general to vacate the terms of the support order.

(4) DCS or the department are not entitled to terms for a party's failure to serve the department within the time requirements for this section, unless the department proves that the party knew that the department had an assignment of support rights or a subrogated interest and that the failure to serve the department was intentional.
