Washington Order On Adequate Cause To Change A Parenting Or Custody Order is a court order issued by a Washington state court which grants permission for a parent to modify an existing parenting or custody order. This order is necessary when a parent wishes to modify provisions of an existing parenting or custody order, such as changing the visitation schedule, relocating with a child, or changing the amount of child support. There are two main types of Washington Order On Adequate Cause To Change A Parenting Or Custody Order: a Motion for Modification of Parenting Plan (MMPP) and an Order for Modification of Parenting Plan (MPP). An MMPP is used when a parent wants to modify existing provisions of a parenting plan, while an MPP is used when a parent wants to modify an existing custody order. Both of these orders require that the requesting parent demonstrate that there is adequate cause to change the existing order.
