To Change (Modify) Child Support using the Simplified Process ("Simplified Mod")

You may use the forms on this page if the following factors apply to your situation :
  • You have a Maricopa County child support order and you believe the amount you pay or receive should be changed, AND,
  • You have completed a "Child Support Worksheet" and the result for Item 35 is different from the amount of your current order by at least 15%, OR
  • You want to assign responsibility or change who is responsible for medical insurance. A modification of the medical assignment or responsibility does not need to vary by 15% or more from the existing child support amount. Typically, this procedure is used when there has been a change in the income of the parent(s), OR
  • There are two or more children and support is no longer owed for one child but is still owed for others.¬†¬†Typically, this procedure is used when there has been a change in the income of the parent(s).

Use the easy-to-use child support calculator at ezCourtForms to create a Child Support Worksheet, Child Support Order, and Current Employer Information form.
