You'll need to check in with your bail bond agency to check that you meet certain criteria to revoke your signature. After you have done that, your agency will advise you on the required paperwork through their contract management software and what evidence you need to give in order to be released from your agreement.
When a judge announces no bond, the defendant isn't eligible for release from county jail through bail as the judge has not set a bail amount. Instead, the arrested person has to remain in custody until the case concludes or a judge potentially sets bail at a later hearing.
California Penal Code Section 825 says that a person arrested in California must be brought before a judge within 48 hours to be charged or released. These rules prevent law enforcement from holding suspects indefinitely while providing sufficient time to collect evidence and decide whether to take the case forward.
Most states allow prosecutors up to 72 hours after an arrest to file charges, although some states, like California, allow only 48 hours. If the prosecutor fails to bring charges within this time limit, the court has to release you. Failure to do that is a violation of your rights.
