Cal. CCP § 996.020

(a) If a bond is given other than in an action or proceeding and it is shown by affidavit of a credible witness or it otherwise comes to the attention of the officer that the bond is or has from any cause become insufficient because the sureties are insufficient or because the amount of the bond is insufficient, the officer may serve an order on the principal to appear and show cause why the officer should not make a determination that the bond is insufficient. The order shall name a day not less than three or more than 10 days after service.

(b) If the principal fails to appear or show good cause on the day named why a determination that the bond is insufficient should not be made, the officer may determine that the bond is insufficient and order a sufficient new, additional, or supplemental bond to be given.

(c) If a sufficient bond is not given within 10 days after the order, the officer shall make an order vacating the rights obtained by giving the original bond, including declaring vacant any office and suspending or revoking any license or certificate for which the bond was given. Any office vacated, license suspended or revoked, or any other rights lost, for failure to give a new, additional, or supplemental bond, shall not be reinstated until a new, additional, or supplemental bond is given.
