Before an action shall be brought by a plaintiff other than the state or body politic named in the bond, leave shall be obtained of the district court of the county in which the action is triable, or a judge thereof, by the production of a copy of the bond and an affidavit showing the delinquency; and, if the delinquency be such that, if established on the trial, it would entitle the applicant to recover, leave shall be granted. Upon the execution issued on a judgment recovered upon the official security of a public officer, against the officer and a surety, there shall be endorsed a direction to the officer to whom the same is delivered to collect the same out of the property of the principal, if sufficient can be found, and, if not, out of the property of the surety.
