California Citation To Appear is a legal summons used by courts in California to notify a person that they must appear in court. It is typically issued when someone fails to respond to a ticket or other court summons. There are two general types of Citation To Appear: a misdemeanor Citation To Appear and a felony Citation To Appear. The misdemeanor Citation To Appear is issued when a person has been charged with a misdemeanor offense, such as a DUI or a petty theft. The felony Citation To Appear is issued when a person has been charged with a felony offense, such as assault or murder. Once the Citation To Appear is issued, the person must appear in court on the date and time listed on the Citation To Appear. Failure to appear in court can result in an arrest warrant being issued.
