All title policies issued by title insurers shall be subscribed by the president or a vice president and by the secretary or an assistant secretary of the corporation. All such title policies are as binding and obligatory upon the corporation as if executed over the corporate seal. The signatures of such officers, or any one of them, may be in their own handwriting or engraved, lithographed, printed, stamped, or otherwise affixed to such title policies. Any title policy so signed shall be presumed to be duly subscribed, and if the title policy provides for an additional signature and such signature appears thereon a like presumption shall apply.
