A Tennessee Summons is a legal document used in the state of Tennessee to summon an individual to appear in court. It is issued by a judge or a court clerk, and can be used to bring a defendant to court to answer a complaint, have a hearing on a motion, or to testify in a case. There are three types of Tennessee Summons: service by certified mail, service by sheriff, and service by posting. Service by certified mail is when the Summons is sent to the defendant through the mail, and must be signed for by the defendant. Service by sheriff is when the Summons is delivered by a sheriff or a process server to the defendant in person. Service by posting is when the Summons is posted on the defendant's door.
