(a) When Depositions May Be Taken. After commencement of the action, any party may take the testimony of any person, including a party, by deposition upon oral examination. Leave of court, granted with or without notice, must be obtained only if the plaintiff seeks to take a deposition prior to the expiration of 30 days after service of the summons and complaint upon any defendant except that leave is not required (1) if a defendant has served a notice of taking deposition or otherwise sought discovery, or (2) if special notice is given as provided in subsection (b)(2) of this rule. The attendance of witnesses may be compelled by subpoena as provided in rule 45.
(b) Notice of Examination: General Requirements; Special Notice; Nonstenographic Recording; Production of Documents and Things; Deposition of Organization.
(1) Notice in General. A party desiring to take the deposition of any person upon oral examination shall give reasonable notice in writing to every other party to the action. The notice shall state the time and place for taking the deposition and the name and address of each person to be examined, if known, and, if the name is not known, a general description sufficient to identify the person or the particular class or group to which the person belongs. If a subpoena duces tecum is to be served on the person to be examined, the designation of the materials to be produced as set forth in the subpoena shall be attached to or included in the notice.
(2) Nonstenographic Recording. The party taking the deposition shall state in the notice the method by which the testimony shall be recorded. Unless the court orders otherwise, it may be recorded by sound, sound-and-visual, or stenographic means, and the party taking the deposition shall bear the cost of the recording. Any party may arrange for a transcription to be made from the recording of a deposition taken by nonstenographic means.
