Bail refers to property or any asset that a plaintiff promises to a court. This is done in exchange for the right to get out of jail. However, bail requires that the person show up in court for trial, otherwise he forfeits the bail.
Usually, bail is granted to an individual if there is some time between his arrest and the court date. This will allow him to somehow live his normal life outside of jail during that period. Whether or not bail will be granted depends on several factors including the nature and severity of the crime and the jurisdiction. The same principle applies to the the determination of the price of the bail.
There are many cases wherein the price of the bail is so high that no average person will be able to afford it. This is where the concept of bail bonding comes into the picture. What happens then is that the person simply has to pay a smaller part of the total bail amount. He will then be allowed to leave jail, but has to pledge the total amount. Bail bondsmen have become the normal choice in this regard - they are professional who post the minimum amount required by court. The plaintiff then has to pay the bail bondsmen a smaller amount, together with the assurance that he will show up in court at a later date. It then becomes the bail bondsman’s responsibility to make sure that his client does not make a run for it.
