A New Jersey Third-Party Summons is a legal document issued by a court in the state of New Jersey for the purpose of bringing a third party into a legal dispute. This type of summons is typically used to bring in someone who was not a party to the original dispute, but whose presence is necessary for the court to make a decision. There are two types of New Jersey Third-Party Summons: a Non-Party Summons and a Subpoena. A Non-Party Summons is issued to a person or entity who is not a party to the original lawsuit, but may have information relevant to the dispute. A Subpoena is issued to a person or entity who is a party to the original lawsuit, but is not present in court.
