Iowa Code Title XV. Judicial Branch and Judicial Procedures [Chs. 595-686] § 622.84. Subpoenas--enforcing obedience

1. When, by the laws of this or any other state or country, testimony may be taken in the form of depositions to be used in any of the courts thereof, the person authorized to take the depositions may issue subpoenas for witnesses, which must be served by the same officers and returned in the same manner as is required in district court, and obedience to the subpoenas may be enforced in the same way and to the same extent, or the person may report the matter to the district court who may enforce obedience as though the action was pending in the district court.

2. If a witness is located in any other state or country and refuses to voluntarily submit to the deposition, the court of jurisdiction in this state may, upon the application of any party, petition the court of competent jurisdiction in the foreign jurisdiction where the witness is located to issue subpoenas or make other appropriate orders to compel the witness' attendance at the deposition.
