The Washington Child Support Schedule Worksheet is a legal form used by the state of Washington to calculate the amount of child support to be paid by a noncustodial parent. This worksheet is used to determine the amount of money to be paid in monthly child support payments. The worksheet is based on the Washington State Child Support Schedule, which is a set of guidelines that takes into account the income of both parents, the number of children involved, and the amount of time each parent will have with the child(men). There are two different types of Washington Child Support Schedule Worksheets: the Basic Worksheet and the Alternate Worksheet. The Basic Worksheet is used to calculate the basic child support obligation for situations that involve one or two children, and the Alternate Worksheet is used for more complex situations involving three or more children.
