Rule 12.320. Depositions Upon Written Questions
(a) Serving Questions; Notice. After commencement of the action any party may take the testimony of any person, including a party, by deposition upon written questions. The attendance of witnesses may be compelled by the use of subpoena as provided in rule 12.410. The deposition of a person confined in prison may be taken only by leave of court on such terms as the court prescribes. A party desiring to take a deposition upon written questions must serve them with a notice stating
(1) the name and address of the person who is to answer them, 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 that person belongs, and
(2) the name or descriptive title and address of the officer before whom the deposition is to be taken.
Within 30 days after the notice and written questions are served, a party may serve cross questions on all other parties. Within 10 days after being served with cross questions, a party may serve redirect questions on all other parties. Within 10 days after being served with redirect questions, a party may serve recross questions on all other parties. The court may for cause shown enlarge or shorten the time.
(b) Officer to Take Responses and Prepare Record. A copy of the notice and copies of all questions served must be delivered by the party taking the depositions to the officer designated in the notice, who must proceed promptly to take the testimony of the witness in the manner provided by rules 12.310(c), (e), and (f) in response to the questions and to prepare the deposition, attaching the copy of the notice and the questions received by the officer. The questions must not be filed separately from the deposition unless a party seeks to have the court consider the questions before the questions are submitted to the witness.
