New York Summons — Third Party, in a Civil Action is a legal document issued by a court of law in a civil action so that an individual or entity outside the plaintiff and defendant can be called upon to provide testimony and/or documents relating to the case. The third-party summons is typically issued when the court believes that the third party has information that is relevant to the trial. There are two types of New York Summons — Third Party, in a Civil Action: the Summons and Notice, and the Subpoena. The Summons and Notice requires the third party to appear in court and provide testimony, while the Subpoena requires the third party to produce documents or other tangible evidence. Both documents must be served in the manner prescribed by law, and the third party has the right to object to the summons.
