Once bail has been set, the defendant or a third party can post the bail to secure the defendant's release from custody. If the defendant cannot afford to post bail, they may seek the assistance of a bail bondsman.
No - if you signed the bond it doesn't matter whether you have a job or not - or whether the bondsman asked you if you did. You are liable as surety on the bond - having a job or not has nothing to do with your liability. Sorry.
Most bond agreements include travel restrictions, confining you to a specific geographic area such as your county or state. These limitations are designed to ensure your availability for court dates. If travel is necessary, you must seek prior approval from the court or your bail bondsman.
