An Indiana Subpoena to Testify at a Deposition in a Civil Action is a legal document issued by a court of law in Indiana, requiring a witness to appear before the court and give testimony as part of a civil action. The subpoena is issued by the court clerk and delivered to the witness, usually by mail, and may be accompanied by a summons or other court documents. The subpoena to testify at a deposition in a civil action is typically used to gather testimony in advance of a trial, and the witness must appear in person to give testimony. There are two types of Indiana Subpoena to Testify at a Deposition in a Civil Action: a subpoena ad testificandum and a subpoena duces tecum. A subpoena ad testificandum is an order to appear in court to give testimony, whereas a subpoena duces tecum requires the witness to bring documents or other items to court in order to provide evidence.
