Municipal bonds must be executed in the name of and for the municipality issuing them, by its qualified officers, who for that purpose shall sign the same by manual or facsimile signatures in their official capacities, as follows:

1. For a county, the chairman of the board of county commissioners and the county auditor.

2. For a city, the mayor or president of the board of city commissioners and the city auditor.

3.    Repealed by S.L. 1967, ch. 323, § 285.

4. For any other municipality, the chairman or president of the governing board and the clerk or secretary thereof, or such other officer as the governing body thereof may determine.

The interest coupons attached to such bonds may be executed by the lithographed or engraved facsimile signature of such officers. The validity of every bond so executed remains unimpaired by the fact that any subscribing officer has ceased to be such officer before delivery to the purchaser. Bonds issued by a municipality having an official seal need not be sealed with such    seal. The city auditor, county auditor, clerk, or secretary or such other officer as the governing body of the municipality may determine shall sign an endorsement on the back of each bond certifying that the bond is issued pursuant to law and is within the debt limit of the municipality issuing the bond.
