Do I have to register my protective order in New Hampshire in order to get it enforced?
No. New Hampshire state law gives full protection to out-of-state protection orders whether or not they’re registered. It does not have to be registered in order to be enforced by a New Hampshire police officer, as long as it seems to the officer that your order is real.1
While you do not have to register your out-of-state protection order in order to get it enforced, one benefit of registration is that you may be able to get your order enforced, even if you are not carrying a copy of the order with you when you call to report a violation of the order. Out-of-state protective orders that are registered in New Hampshire are kept in the New Hampshire State Protective Order Registry, and New Hampshire police officers should have access to this registry when they come on the scene.
