Essentially when the criminal case is over and the defendant has fulfilled their obligation to the court. When the court finishes with the defendant’s case, the bond will be known as being exonerated. At that time the defendant must pay all applicable court fees and the Las Vegas bail bonds will have been cleared. It is the responsibility of the defendant or co signer to deliver bond release documents to the bonding agent however. At that point, collateral is usually returned by the Las Vegas bail bondsman.
