Child Support Worksheets
Use Worksheet A when one parent (or a third party) has primary physical custody of all of the children for whom support is being determined. A parent (or third party) has primary physical custody of a child if the child lives with that parent (or custodian) for at least 243 nights during the year. Primary physical custody is determined without regard to whether a parent has primary, shared, or joint legal custody of a child. Do not use Worksheet A when (a) a parent has primary custody of one or more children and the parents share custody of one or more children [instead, use Worksheet B] or (b) when primary custody of two or more children is split between the parents [instead, use Worksheet C]. In child support cases involving primary physical custody, a child support obligation is calculated for both parents but the court enters an order requiring the parent who does not have primary physical custody of the child to pay child support to the parent or other party who has primary physical custody of the child.
Use Worksheet B when (a) the parents share custody of all of the children for whom support is being determined, or (b) when one parent has primary physical custody of one or more of the children and the parents share custody of another child. Parents share custody of a child if the child lives with each parent for at least 123 nights during the year and each parent assumes financial responsibility for the child's expenses during the time the child lives with that parent. A parent does not have shared custody of a child when that parent has visitation rights that allow the child to spend less than 123 nights per year with the parent and the other parent has primary physical custody of the child. Shared custody is determined without regard to whether a parent has primary, shared, or joint legal custody of a child. Do not apply the self-sufficiency reserve incorporated into the shaded area of the schedule when using Worksheet B.
