I was granted temporary custody with my protective order. Will another state enforce this custody order?
Yes. Custody, visitation, and child support provisions that are included in a protective order can be enforced across state lines. Law enforcement and courts in another state are required by federal law to enforce these provisions as long as the protective order is good under federal law.* See How do I know if my protection order is good under federal law? for more information.
