An Iowa Deposition Subpoena in a criminal case is a legal document that requires a person to appear in court to give testimony. The deposition subpoena is issued by a judge to the person or entity being subpoenaed. It orders that person to appear at a specified time and date to provide testimony in a criminal case. The deposition may be in-person or conducted via video conference. There are two types of Iowa Deposition Subpoena in a Criminal Case: a witness deposition subpoena and a deposition subpoena duces tecum. A witness deposition subpoena requires the witness to appear in court and provide testimony, while a deposition subpoena duces tecum requires the witness to bring documents or other physical evidence to court. Both types of deposition subpoena must be served on the person being subpoenaed according to Iowa law.
