N.H. Rev. Stat. § 358-A:5
At least 10 days prior to commencement of any action under RSA 358-A:4, the attorney general shall notify the person of the attorney general's intended action, and give the person an opportunity to confer with the attorney general, or agent, in person or by counsel or other representative as to the proposed action. Said notice shall be given by mail, postage prepaid, sent to the person's usual place of business, or, if none, to the person's last known address. Such notice need not be given if the attorney general has reason to believe that any potential recipient of such notice may after receipt thereof destroy or move or cause to be destroyed or cause to be moved any assets which might otherwise be available to claims of restitution, leave the state or cause material witnesses to leave the state, or take other action or omit to perform other duties to the immediate and irreparable harm of the public.
