At the time you are sentenced, the Judge and Clerk can set up installment payments. These payments are also set on the Pay or Appear docket. As long as payments are made according to the Pay or Appear agreement, then you will not be required to appear in Court.
If you fail to pay as agreed and also fail to appear in Court, a warrant can be issued for your arrest. If there is a problem with making the agreed upon payment and/or not being able to appear, contact the Court Clerk prior to your scheduled court date.
