If you have children who are younger than 18 or 18 but still enrolled in and attending high school, you will need to prepare a child support worksheet.
The worksheet will calculate child support based upon the date entered into the worksheet. The amount of child support calculated by the worksheet is called the presumptive amount, but it can be changed upward or downward in appropriate circumstances.
