An Arizona Petition To Modify Child Support Order (Standard Procedure) is a legal document that is used to request a change in the amount of child support a parent pays or receives. The petition must be filed with the court in the county where the original child support order was issued. There are two types of Arizona Petition To Modify Child Support Order (Standard Procedure): 1. Petition for Child Support Modification: This petition is used when the parent wants to increase or decrease the amount of child support paid to or received from the other parent. 2. Petition for Child Support Enforcement: This petition is used when a parent is not paying the court-ordered amount of child support. In either case, the parent filing the petition must provide the court with their financial information and provide evidence supporting their claim. The court will review the petition and make a decision based on the best interests of the child.
