The Massachusetts Child Support Guidelines Worksheet is a form used to calculate the amount of child support that should be paid by one parent to the other. The worksheet considers the income of both parents, the number of children in the family, and the amount of time each parent spends caring for the children in order to determine a fair amount of support. There are two types of Massachusetts Child Support Guidelines Worksheet available: the short form and the long form. The short form is for when both parents have similar incomes and the time spent caring for the children is equal. The long form is for when the incomes or parenting time differ significantly between the two parents. The long form also allows for other factors to be taken into consideration, such as health insurance costs, day care expenses, and other special needs of the children.
