When you are served with court papers, they will include a date on which you must go to court. This date is called a first appearance. You must go to court on this date; if you don't, you will probably lose. At your first appearance, you can ask for a number of things, such as more time to move out, or for a settlement with your landlord. You can also ask for a trial. If you ask for a trial you will have to answer the landlord's complaint. When you file your answer (usually on the date of your first appearance), you will be given a trial date.
