In our blog we will try and give updates on the law and cases throughout New Hampshire, as well as interesting events that occur throughout the country.
Yes, in the State of New Hampshire you are legally allowed to use non-deadly force when you reasonably believe that such force is necessary to prevent or terminate criminal trespass. The statute codifying this is NH RSA 627:7 - Use of Force in Defense of Premises.
"A person in possession or control of premises or a person who is licensed or privileged to be thereon is justified in using non-deadly force upon another when and to the extent that he reasonably believes it necessary to prevent or terminate the commission of a criminal trespass by such other in or upon such premises, but he may use deadly force under such circumstances only in defense of a person as prescribed in RSA 627:4 or when he reasonably believes it necessary to prevent an attempt by the trespasser to commit arson."
The statute is relatively narrow. Shooting at someone on your lawn, is not advisable.
