A corporation may, but need not, have a corporate seal, and the use or nonuse of a corporate seal does not affect the validity, recordability, or enforceability of a document or act. If a corporation has a corporate seal, the use of the seal by the corporation on a document is not necessary.
If a corporation has a corporate seal, the seal may consist of a mechanical imprinting device, or a rubber stamp with a facsimile of the seal affixed thereon, or a facsimile or reproduction of either. The seal need include only the word "Seal," but it may also include a part or all of the name of the corporation and a combination, derivation, or abbreviation of either or both of the phrases "a Minnesota Corporation" and "Corporate Seal." If a corporate seal is used, it or a facsimile of it may be affixed, engraved, printed, placed, stamped with indelible ink, or in any other manner reproduced on any document.
