Knowing what the bail amount is, is an important first step to knowing what it will cost to bail someone out of the Bexar County jail. The amount is set by a judge, either a magistrate or a county or district judge. The amount will usually depend on the gravity of the crime, as well as the flight risk. In the United States, the 8th Amendment of the Constitution prevents excess bail. This is based on the principle that everyone is innocent until proven guilty, and therefore entitled to freedom while awaiting a fair trial. If it is set too high, a motion can be filed to attempt to reduce the amount of even to try to obtain a personal recognizance bond. If you need to know what the amount is for a specific case, please give our office a call at 210-224-5245.
