N.C. Gen. Stat. § 1-423: Qualifications of bail.

The qualifications of bail must be as follows:

(1) Each of them must be a resident and freeholder within the State

(2) They must each be worth the amount specified in the order of arrest, exclusive of property exempt from execution; but the judge, on justification, may allow more than two bail to justify severally in amounts less than that expressed in the order, if the whole justification is equivalent to that of two sufficient bail. (C.C.P., s. 164; Code, s. 306; Rev., s. 740; C.S., s. 781.)
