N.H. Cir. Ct. Dist. Div. R. 3.16 (pre-e-filing)

A. The signatures and indorsements of all written instruments declared on will be considered as admitted unless the defendant shall file a notice within thirty days after the return day at which the writ is entered that they are disputed.

B. Any party desiring to obtain admission of the signature on or the genuineness of any relevant document or of any relevant facts which he believes not to be in dispute, may, after the return day of the action without leave of Court, serve an original request therefor, accompanied by any documents involved, to the adverse party or his attorney. Each of the matters, of which an admission is requested, shall be deemed admitted unless within thirty days after such service the party requested serves a copy thereof to the party requesting such admission, or his attorney, either a sworn denial thereof or a written objection on the ground of privilege or that it is otherwise improper.

C. If objection is made to part of a request, the remainder shall be answered within the time limit, and when good faith requires that a party qualify his answer or deny only a part of a matter, he shall specify so much of it as is true and qualify or deny the remainder.

D. Any party who without good reason or in bad faith denies under this subsection or subsection (A) of this rule any signature or fact which has been requested and which is thereafter proved or who without good reason or in bad faith requests such admission under this rule and thereafter fails to prove it may, on motion of the other party, be ordered to pay the reasonable expense, including attorney's fees, incurred by such other party in proving the signature or fact or in denying the request, as the case may be.
