Arizona Rules of Family Law Procedure

Rule 86. Harmless Error

Unless justice requires otherwise, an error in admitting or excluding evidence–or any other error by the court or a party–is not grounds for granting relief under Rule 83, or for vacating, modifying, or otherwise disturbing a judgment or order. At every stage of the proceeding, the court must disregard all errors and defects that do not affect any party’s substantial rights.
