Bail and a bail bond are two very different things. Bail is the amount of money that is required by the court for a person to obtain early release after an arrest. Bail is set in one of two ways. The first way is through an arraignment hearing where the defendant goes in front of a judge and the details of the case are discussed. This include the severity of the crime, the defendant's past criminal history and whether or not the defendant poses a high risk of flight if they are allowed to get out of jail before their hearing.
A bail bond is the legal and binding contract between the bail bonds agent, the defendant and the co-signer. Per Nevada state law, there is a 15% non-refundable, non-negotiable premium that must be paid. The total cost of the premium is 15% of the total bail amount as well as any filing charges that are tacked on by the jail or court system. If bail is posted, the defendant is allowed to leave the jail and go home as long as they promise to return for their next scheduled court hearing.
