Okla. Stat. tit. 12A, § 3-416
Oklahoma Code Comment
1. Generally, an instrument's transferor warrants that there is no forgery or alteration and the instrument is not subject to any defense or claim in recoupment, the theory being that no transferee would knowingly take an instrument that could not be enforced. However, the transferor makes no warranty as to the obligor's creditworthiness or the sufficiency funds in the drawer's account, except the warranty in sub section 3-416(a)(5) relating to bankruptcy. A similar warranty provision in Section 4-207 applies to transfers within the banking system. If an Article 4 warranty applies, then Article 3 warranties do not. See UCC § 4-102(a).
2. A claim for breach of warranty on grounds of an alteration or unauthorized indorsement may be precluded or mitigated pursuant to Sections 3-401 through 3-407, or Section 4-406. See, e.g., W.R. Grimshaw Co. v. First Nat'l Bank & Trust Co. of Tulsa, 563 P.2d 117 (Okla. 1977). If an indorsement was forged as part of a scheme involving theft of the instrument, then there may be additional remedies for recovery of the instrument, on the underlying obligation, or in conversion, under Sections 3-309, 3-310 or 3-420. Under pre-revision sub section 3-417(3), absolute liability for breach of the warranty that no defense was good against the transferor could be avoided by a transfer "without recourse," but current Section 3-416 changes this because disclaiming indorsement liability is not equivalent to disclaiming warranty liability See UCC § 3-416 Official Comment 3. In this regard, the 1992 UCC revisions to this Section changed the prior law. Compare Cressler v. Brown, 79 Okla. 170, 192 P. 417 (1920), with State Exchange Bank of E& City v. Traders' Nat'l Bank of Kansas City, Mo., 70 Okla. 266, 174 P. 799 (1918). Another change is that warranty liability can no longer be disclaimed, by any language, with respect to a check. UCC § 3-416(c).
