The Department of Social Services is a party in interest and is subrogated to the right of any dependent child or custodian to prosecute or maintain any support action or execute any administrative remedy existing under the laws of this state to obtain reimbursement of public money expended for or on behalf of the child. If a court order, administrative order, or final decree of divorce enters judgment for an amount of support to be paid by a parent or other responsible person, the department is subrogated to the debt created by such order, and any money judgment shall be in favor of the department.
