When a court or administrative order does not contain language regarding abatement based on incapacitation of the person required to pay support and the department receives notice that the person is currently undergoing court-ordered behavioral health treatment, the department must refer the case to the appropriate forum for a determination of whether the order should be modified or amended to:
(1) Contain abatement language as provided in RCW 26.09.345; and
(2) Abate the person's child support obligation due to current incapacitation in accordance with RCW 26.09.345.
