N.H. Rev. Stat. § 511-A:5
The order of the court may be filed with the register of deeds as to real estate or with the secretary of state as to personal property, by the plaintiff or his attorney, without further notice to the defendant. Where notice of such order needs to be given to any trustee, such order shall be served upon the trustee in such manner as may be prescribed by rules of the superior court. Such attachments shall be effective against any trustee, the defendant and all others, except bona fide purchasers for value, as of the time of service or as ordered by the court. Such attachments shall not be effective against bona fide purchasers for value until attachments of real estate have been recorded in the registry of deeds for the county or counties in which the real estate lies or until other attachments are filed with the secretary of state. Fees payable for such recordings or filings shall be in accordance with RSA 478:17-g. As between attaching creditors, all attachments made in conformity with this chapter shall have priority in the order of service of notice on the defendant as provided by RSA 511-A:2.
