I have a temporary restraining order (TRO). Can it be enforced in another state?
Yes. A temporary restraining order can be enforced in other states as long as it meets the requirements listed in How do I know if my protection order is good under federal law?
Note: The state where you are going generally cannot extend your ex parte temporary order or issue you a permanent order when the temporary one expires. If you need to extend your temporary order, you will have to contact the state that issued the order and arrange to be at the hearing in person or by telephone (if that is an option offered by the court). However, you may be able to reapply for one in the new state that you are moving to if you meet the requirements for getting a protective order in that state – but, if you apply for one in a new state, the abuser would know what state you are living in, which may put you in danger.
