Did you know that on a child support calculator there are items that are "discretionary" and not "mandatory" to include? This includes such things as "support of other natural or adopted children" (referred to sometimes as after-born children). In a recent case in Arizona a Judge ruled that these "other children" were not to be included in a child support worksheet in a family law case since the parties had equal parenting time and equal pay. Make sure you know the right way to complete a child support worksheet in your case.
