Bail is initially set by the arresting officer or the watch commander. It is usually set according to a bail schedule published by the Court in each county. Many defendants will receive an "own recognizance" (O.R.) release and will not have to post bail.
Bail reduction motions can first be made at the arraignment. There are also other (but limited) opportunities to bring a motion to reduce bail.
Bail is made with cash or a bond. A bond requires a 10% fee to a bondsman plus collateral. The 10% is the bondman's fee and will not be returned. Cash bail is returned, less a small administrative fee, when the case is over. We often can help you find a bondsman who will work diligently to arrange bail (often including payments on their fee) with eased collateral requirements.
