There are four primary types of bonds: Cash Only, Secured, Unsecured, and Signature or Own Recognizance sometimes called "OR").
Cash Only: The defendant,
a co-signer, and/or a bondsman must pay a designated amount of money directly
to the Court. The defendant and/or a co-signer, where applicable, must also
sign a bond order guaranteeing the appearance of the defendant at all further
Secured: The defendant must pay a designated amount of money or provide the Court or the bonding agent with security, such as title to property, stock certificates, etc., with a value equivalent to the prescribed bond amount. In addition, the defendant, and/or the co-signer, or the bonding agent, as applicable, must then sign a bond order guaranteeing the defendant's appearance for all further Court proceedings.
Unsecured: Defendants sign a bond, quite often with bonding agents, guaranteeing their appearance at all further Court hearings, subject to the understanding that if the accused don't appear, they will be responsible for paying the Court a designated amount of money. In certain instances, a hearing officer may require a responsible third party, such as a defendant's relative; sign the bond on behalf of the accused.
Signature Bond or Release on the Defendants' Own Recognizance ["ROR"]: The defendants sign bond orders personally guaranteeing their appearances at all proceedings. Signature Bonds are typically issued in lower risk situations, where
 The defendant's established reputation and stature in the community strongly suggest reliability,
 The charges are relatively unsubstantiated, especially in light of the defendant's ability to mount an aggressive defense,
 Even the consequences of a conviction can't justify the destructive impact certain to result from fugitive flight to avoid prosecution.
BAIL REFUNDABLE AFTER THE CASE IS FINISHED?
The percentage of the total bond amount that you pay to the bail bond agency, technically referred to as the premium, represents the fee the bondsman charges to pay or pledge the full bond amount to the court. Like a premium payment on any insurance policy, the premium on a surety bond is non-refundable. This fee is what allowed the defendant to get out of jail and is fully earned once the defendant is released from custody.
