Desk Appearance Ticket (D.A.T.)
A Desk Appearance Ticket (D.A.T.) is a written notice to appear in Court for Arraignment—where criminal defendants are formally advised of their charges and asked to enter a plea. D.A.T’s are often issued after an arrest for a Violation or Misdemeanor instead of being placed in jail. They are occasionally issued for Felonies. A D.A.T. must be taken seriously as it is not a get out of jail free card. The arraignment is only a first appearance in court, and jail time, fines, probation, community service, and more may follow.
