N.H. Rev. Stat. § 358-H:8
A rental referral agency shall post a surety bond of not less than $20,000 with the attorney general, department of justice. The type of surety bond shall be designated by the attorney general. No bond shall be accepted for filing unless it is with a surety company authorized to do business in this state. The surety may cancel the bond at any time upon giving 30 days' written notice to the attorney general. Any person who is damaged by any violation of this chapter, or by the rental referral agency's breach of the contract subject thereto, may bring an action against the bond to recover damages suffered and any other amounts allowable by law. The attorney general, in an action brought under this chapter or any other applicable provision of law, may likewise proceed against the bond. In no event shall the aggregate liability of the surety for all claims exceed the bond amount.
