A Bail Bond is essentially collateral that a person or company posts on an individual's behalf to guarantee that an individual will show up for his/her court appearance. Posting collateral in the form of money or property in exchange for an individual's temporary release from jail pending a court appearance dates back to 13th century England where there was a greater need to create a balance among the rich, middle, and poor classes on temporary releasing someone from jail when individuals were accused of a crime.
In early England, only those who had enough money and property to post as security were fortunate enough to secure temporary release from jail pending a return to court for an appearance. Savvy individuals came to the conclusion that with enough capital, they could offer this security to the court in a defendant’s name after receiving a percentage of the amount as insurance. Thus, "Bondsmen" were created who would then accept a percentage of the bail needed and post the rest for someone who has been charged with a crime and is hoping to be released from custody pending appearances at future court dates. The "fees" involved when using a commercial bond service is how the Bondsmen earn their profit.
