The sound of a jail cell closing shut is not something anyone ever wants to hear, but now you've got to try and get yourself out of a bad situation. Fortunately, the justice system provides a way for some defendants to get out of jail pending their trial, and that's the opportunity to post bail. Bail can be expensive though, and that's why bail bond companies are in business. If you've never been in this situation before though, you might not be sure where to begin.
