If there is only one (1) surety, that surety shall be worth the amount specified in the bond exclusive of the amount of any other undertaking on which the surety may be principal or surety, and exclusive of property exempt from execution and over and above liabilities. If there are several sureties they shall in the aggregate be worth that amount exclusive of the amount of other undertakings, and of the exemptions and liabilities mentioned above. Any person authorized to take bail shall refuse any surety offered in a bail bond to be taken by that person who is, in that person’s opinion, insufficient.
