New Hampshire is best classified as statutory stand-your-ground. New Hampshire provides by statute that a person need not retreat if anywhere they have a right to be and were not the initial aggressor before using otherwise justified deadly force. Civil immunity is available for justified force. That is what separates New Hampshire stand-your-ground and the duty to retreat from a generic national summary. Read N.H. Rev. Stat. Ann. § 627:4 before the background sections below. Justified force also carries meaningful civil-immunity protection.
