Where a bond is tendered by a guardian with personal sureties, there shall be at least two (2) sureties and they shall file with the court a certificate under oath which shall describe the property owned, both real and personal, and shall state that each is worth the sum named in the bond as the penalty thereof over and above all his or her debts and liabilities and the aggregate of other bonds on which he or she is principal or surety and exclusive of property exempt from execution. The court may require additional security or may require a corporate surety bond, the premium on the bond to be paid from the ward‘s estate.
