N.H. Rev. Stat. § 511-A:3
When a defendant objects to the making of attachments, the court shall set a hearing on such objection within 14 days of the receipt of such objection. Upon hearing, the burden shall be upon the plaintiff to show that there is a reasonable likelihood that the plaintiff will recover judgment including interest and costs on any amount equal to or greater than the amount of the attachment. Upon satisfying said burden, the plaintiff shall be entitled to the attachment unless the defendant establishes to the satisfaction of the court that his assets will be sufficient to satisfy such judgment with interest and costs if the plaintiff recovers same. Such hearings shall not be bound by the rules of evidence. The court may appoint such masters, referees or magistrates as may be necessary to conduct such hearings.
