I was granted temporary custody with my order for protection. Will another state enforce this custody order?
Yes. Custody, visitation, and child support provisions that are included in an order for protection can be enforced across state lines. Law enforcement and courts in another state are required by federal law to enforce these provisions.1 However, before leaving the state, it is important to talk to a lawyer to make sure that leaving the state would not violate any laws such as parental kidnapping (custodial interference) laws, or any laws that your state may have regarding not removing a child from the state during a court case.
