  • You have completed a "Parent's Worksheet for Child Support" 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).

  • If your order is from a court outside this county (unless an attorney has advised you to);
  • If the amount of the change in the order is not at least 15%;
