In all cases not otherwise provided for in titles 2 to 6, inclusive, of NRS, where sureties are required to justify, they shall appear before the officer or person authorized to take the justification, and may be examined under oath by such officer or person and the adverse party, touching their qualifications as sureties, which examination shall be reduced to writing and subscribed by the sureties if required. If, upon such examination, it shall appear to such officer or person that the sureties, or either of them, have the necessary qualifications of such, the officer or person shall so endorse upon the statement, and cause the same to be filed, and thereupon the justification shall be complete.
