Child support services are provided under the Office of the Attorney General, Child Support Services Division. The amount of child support is determined through guidelines that use factors such as the income of the parents, number of payments sent or received through other custody arrangements, public benefits, medical expenses and insurance costs. There is also a provision for “extraordinary” medical expenses that are accrued while raising the child. Additional considerations are made for self-employment and the taxable income generated through self-employment. Through this comprehensive formula, guidelines will be determined that will give both parents an idea of how much child support will need to be paid. Payments can be made by mail or online through an electronic payments automated clearing house network. Different PO boxes are maintained for different types of support payments to be made by parents, employers and state agencies.
