There are three requirements for obtaining a Judicial Court Bond: Submit an application and signed indemnity agreement supplied by the surety broker/agent; Provide a copy of the court papers for the applicable action being filed; and. Provide collateral, usually in the form of an Irrevocable Letter of Credit.
Depending on the type of crime the suspect is arrested for, the bond amount may be given right after booking or the suspect may have to sit in jail for a couple days before a bond hearing before a judge.
