In OCGA 14-5-7 (a), the legislature imposed a limitation on the specific types of corporate officers who could execute instruments for real estate conveyances other than those releasing security agreements. Consequently, the Court must presume that the legislature's failure to include similar limiting language in OCGA 14-5-7 (b) "was a matter of considered choice." Transp. Ins. Co. v. El Chico Restaurants, 271 Ga. 774, 776 (524 SE2d 486) (1999). OCGA 14-5-7 (a) provides: Instruments executed by a corporation conveying an interest in real property, when signed by the president or vice-president and attested or countersigned by the secretary or an assistant secretary or the cashier or assistant cashier of the corporation, shall be conclusive evidence that the president or vice-president of the corporation executing the document does in fact occupy the official position indicated; that the signature of such officer subscribed thereto is genuine; and that the execution of the document on behalf of the corporation has been duly authorized. Any corporation may by proper resolution authorize the execution of such instruments by other officers of the corporation.
