Child Support Questionnaire

Child Support Modifications

The filing fee for post-adjudication (if you already have an existing case in Maricopa County Superior Court) petitions (i.e. motion to enforce or change child support)is $84.00.  If it is a new case that has not been filed in Maricopa County Superior Court, the filing fee is $338.00.

Child Support Guidelines (with instructions):  This amount is then divided by the ratio of each parent's monthly income to the parents' total combined income (i.e. if Mother makes 40% and Father makes 60% and Mother is ordered to pay child support, then Mother would pay 40% of the child support amount).
