Oklahoma Code Comment

1. Section 3-403 clarifies the rule when a payor pays or takes an instrument containing less than the required number of signatures. Subsection (b) specifies that if more than one signature is required to constitute the authorized signature of an organization, then the organization's signature is unauthorized if one of the required signatures is missing. The same result is reached if one of the required signatures is forged, pursuant to the definition of "unauthorized" in sub section 1-201(43) . Thus, for example, a paper bank that pays a check containing less than the required number of drawers' signatures or containing a forged drawer's signature has paid over an "unauthorized" signature, triggering the one-year limitation period for the customer's suit contained in sub section 4-406(f) (pre-revision sub section 4-406(4) ) . Section 3-403 resolves the split of authority on the issue found in Far West Citrus, Inc. v. Bank of America National Trust & Savings Association, 91 Cal. App. 3d 913,154 Cal. Rptr. 464 (1979) (payment was over "unauthorized" signature) and Pine Bluff National Bank v. Kesterson, 257 Ark. 813, 520 S.W.2d 253 (1975) (payment was over "authorized" signature).

2. Although the bank pays over an unauthorized signature, certain mitigating conditions may protect the bank from liability. Those conditions may include ratification of the unauthorized signature, estoppel or preclusion, or a valid defense. See, e.g., Eutsler v. First Nat'l Bank, Pawhuska, 639 P.2d 1245 (Okra. 1982) (ratification); Guaranty Bank & Trust Co. v. Federal Reserve Bank of Kansas City, 454 F.Supp. 488 (W.D. Okla. 1977) (ratification); W.R Grimshaw Co. v. First Nat'l Bank & Trust Co. of Tulsa, 563 P.2d 117, 122-23 (Okra. 1977) (estoppel); and the Oklahoma Comment to Section 4-401 .
