If the final decision of the department or courts on appeal is that the division of child support (DCS) has caused money or property that is exempt from satisfaction of the NCP's child support obligation to be withheld by the bank or delivered to the department, DCS must:

(1) Promptly release the order to withhold and deliver; or

(2) Refund the proportionate share of the funds having been identified as being exempt. The department is not liable for any interest accrued on any money withheld under RCW 74.20A.080.
