A party may compel the witness to attend the deposition on written questions by serving the witness with a subpoena under Rule 176. If the witness is a party or is retained by, employed by, or otherwise subject to the control of a party, however, service of the deposition notice upon the party's attorney has the same effect as a subpoena served on the witness.
The deposition officer must: take the deposition on written questions at the time and place designated; record the testimony of the witness under oath in response to the questions; and prepare, certify, and deliver the deposition transcript in accordance with Rule 203. The deposition officer has authority when necessary to summon and swear an interpreter to facilitate the taking of the deposition.
