N.H. Cir. Ct. Dist. Div. R. 3.23 (pre-e-filing)

(a) Costs. Costs shall be allowed as of course to the prevailing party as provided by these rules, unless the Court otherwise directs.

(b) Taxation of Costs. The party claiming costs shall file with the Clerk an itemized, verified bill of costs. The Clerk shall revise the verified bill of costs to conform to these rules. No costs shall be taxed by the Clerk in any case except the fees of the Clerk, fees for the service of process, and witness fees, unless the same shall be agreed to in writing by the adverse party or the party's attorney. If a party objects to any costs allowed or not allowed by the Clerk, such party may by motion request that the Presiding Justice review the action of the Clerk. Any party aggrieved by the Presiding Justice's order concerning costs may appeal therefrom within 30 days from the date of notice of such order, regardless of whether an appeal concerning the underlying judgment is sought.

(c) Allowable Costs. The following costs shall be allowed to the prevailing party: Fees of the Clerk, fees for service of process, witness fees, expense of view, cost of transcripts, and such other costs as may be provided by law. The court, in its discretion, may allow the stenographic cost of an original transcript of a deposition, plus one copy, including the cost of videotaping, and may allow other costs including, but not limited to, actual costs of expert witnesses, if the costs were reasonably necessary to the litigation.
