The qualifications of bail must be as follows:
(1) Each of them must be a resident and householder or freeholder within the county.
(2) Each must be worth the amount specified in the order of arrest or the amount to which the order is reduced, as provided in this chapter, over and above all the bail's debts and liabilities, exclusive of property exempt from execution. However, the judge or clerk, on justification, may allow more than two sureties to justify severally, in amounts less than that expressed in the order, if the whole justification is equivalent to that of two sufficient bail.
