N.H. R. Cir. Ct. Prob. Div. 40
When a statute requires notice of the taking of depositions to be given to the adverse Party, it may be given to such Party or to the Party's Attorney of record. In cases where the action is in the name of a nominal Party and the Petition, Motion, Pleading, or docket discloses the real Party in interest, notice shall be given either to the real Party in interest or to the Attorney of record. Notices given pursuant to this Rule may be given by mail or by service in hand. If a subpoena duces tecum is to be served on the deponent, the notice to the adverse party must be served before service of the subpoena, and the materials designated for production, as set out in the subpoena, must be listed in the notice or in an attachment.
