(1) Unless otherwise specified in a court or administrative order, the support order is automatically reinstated as follows:

(a) Effective the first day of the fourth full month after the NCP is released from confinement, support is reinstated at fifty percent of the support amount provided in the underlying order, but not less than the presumed minimum obligation of $50 per month per child; and

(b) Effective one year after release from confinement, support is reinstated at one hundred percent of the support amount provided in the underlying order.

(2) DCS informs the parties in writing at their last known address when reinstating support at fifty percent and one hundred percent.

(3) If the support order is modified under RCW 26.09.170 or RCW 74.20A.059 during the period of abatement, this provision regarding reinstatement of support at fifty percent in subsection (1) of this section does not apply. DCS enforces the modified support obligation.
