The Washington Petition to Enforce Out-of-State Custody Order is a legal document used to enforce an out-of-state custody order in the state of Washington. This petition is used when a parent who has a valid out-of-state custody order has been denied their custodial rights. The petition requests that the Washington court recognize the out-of-state order and issue an enforcement order for the parent to be able to assert their custodial rights. There are two types of Washington Petition to Enforce Out-of-State Custody Order: one for a non-parent custodian and one for a parent custodian. The non-parent petition is filed by a person or entity who is not related to the child, but who has been granted custody in an out-of-state court. The parent petition is filed by a parent who has been granted custody in an out-of-state court. Both petitions must include the name and address of the custodian, the out-of-state court order, and a copy of the order.
