Unsecured bail bond means a bond that holds a defendant liable for a breach of the bond’s conditions. In an unsecured bail bond the defendant signs a contract and agrees to appear before the court. If s/he fails to do so, s/he promises to pay later the agreed bail bond amount before the court. An unsecured bail doesn't require that the money be offered up front. Further, an unsecured bail bond is not secured by a deposit of or lien on property. For instance, a bail bond executed before a court without deposit of or lien on property is an unsecured bail bond.
