N.Y. Civil Practice Law & Rules § 3107: Notice of taking oral questions

Rule 3107. Notice of taking oral questions. A party desiring to take

the deposition of any person upon oral examination shall give to each

party twenty days' notice, unless the court orders otherwise. The notice

shall be in writing, stating the time and place for taking the

deposition, the name and address of each person to be examined, if

known, and, if any name is not known, a general description sufficient

to identify him or the particular class or group to which he belongs.

The notice need not enumerate the matters upon which the person is to be

examined. A party to be examined pursuant to notice served by another

party may serve notice of at least ten days for the examination of any

other party, his agent or employee, such examination to be noticed for

and to follow at the same time and place.
