Okla. Stat. tit. 12A, § 3-206
Oklahoma Code Comment
Official Comment 3 to this Section notes that the Section does not displace the law of waiver as it may apply to restrictive indorsements. In O'Petro Energy Corp. v. Canadian State Bank, 837 P.2d 1391 (Okla. 1992), the court found that where a check bore the restrictive indorsement "for deposit only," but was deposited into an account different than that of the named party on the front of the check, the depositary bank nonetheless was not liable. Under the circumstances, the court determined that the accompanying deposit slip (directing deposit to the different account) had "canceled the [restrictive] indorsement out the same as if [the person indorsing the check and making the deposit, with authority to do so] had drawn a line through the restriction and further negotiated the check with his personal indorsement." O'Petro, 837 P.2d at 1394. Further, the court noted, "Of course if a bank fails to abide by a restrictive endorsement (sic) per se, absent a waiver, it does so at its peril." Id. (citing Rutherford v. Darwin, 95 N.M. 340, 622 P.2d 245 (Ct. App. 1980)). See also UCC § 3-201, Oklahoma Comment.
