Okla. Stat. tit. 12A, § 8-202
Oklahoma Code Comment
Section 8-202 applies if an issuer alleges that a security is not valid. This Section governs the defenses to validity that such an issuer can assert against a purchaser for value and without notice of the defect in question. This follows the prevailing case law and clarifies, but does not substantively change, pre-revision Article 8.
