N.H. Super. Ct. Civ. R. 13

(a) A non-moving party may object or otherwise respond to a motion within 10 days after filing thereof unless: (1) the party is responding to a Motion for Summary Judgment, see RSA 491:8-a; or (2) another deadline is established by court order.

(b) Unless a party requests oral argument or an evidentiary hearing on any motion filed by the party, or on any objection thereto by another party, setting forth by memorandum, brief statement or written offer of proof the reasons why the oral argument or evidentiary hearing will further assist the court in determining the pending issue(s), no oral argument or evidentiary hearing will be scheduled and the court may act on the motion on the basis of the pleadings and record before it. Except with respect to motions that fall within Rules 13(a)(1) and (2) above, such memorandum, brief statement or written offer of proof shall be filed within 10 days after the filing of the motion. With respect to motions that fall within Rule 13(a)(1), such memorandum, brief statement or written offer of proof shall be filed within 30 days after the filing of the motion. With respect to motions that fall within Rule 13(a)(2), such memorandum, brief statement or written offer of proof shall be filed within the deadline established by court order. Failure to object shall not, in and of itself, be grounds for granting the motion.
