The Arizona Petition To Modify Support Order (Standard Process) is a legal process used to change an existing court-ordered support order. This process is available to people who are already involved in an Arizona family law case and have an existing support order. The petitioner must provide evidence of a substantial and continuing change of circumstances that was not foreseeable at the time the order was entered. The types of Arizona Petition To Modify Support Order (Standard Process) include spousal maintenance, child support, medical support, and educational support. The process involves filing a petition with the court, serving the other party with notice, and attending a hearing. After the hearing, the court will issue a new order to reflect the changes.
