The most basic definition of an appearance bond is money you pay to get out of jail under a promise that you will appear in court at your scheduled court date. If you get arrested for something, you might not be able to go to court immediately. Often times, there are at least a couple of days before your court date.
The defendant has two options for these bonds. First is to pay the entire amount of the bail set by the Judge to the court. (EX: $ 10,000 bond = $10,000 to the court). The second option is that a state licensed bail bond agency can post the bond on the defendant’s behalf for 10% of the set bond amount.
