(1) Whenever the Department of Human Services has accepted custody of a child under the provisions of ORS 418.015 and is required to provide financial assistance for the care and support of the child, the state shall, by operation of law, be assignee of and subrogated to any right to support from any other person including any sums that may have accrued, up to the amount of assistance provided by the department. If the right to support is contained in a judgment or order that requires a single gross monthly payment for the support of two or more children, the assignment and right of subrogation shall be of such child's proportionate share of the gross amount. The assignment shall be as provided in ORS 412.024.
