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.1 However, even if your custody order is enforceable in another state, you may need to seek a judge's permission before trying to leave. See I was granted temporary custody with my protective order. Can I take my kids out of the state?
