Okla. Stat. tit. 12A, § 3-311
Oklahoma Code Comment
1. Under Oklahoma common law, acceptance could be under protest. See White v. 32 Okla. 479, 122 P. 156 (1912). This principle was incorporated into the Code by Section 1-103 and pre-revision Section 1-207 . Section 1-207 , however, does not apply to accord and satisfaction.
Thus, Section 3-311 changes the current law in Oklahoma, if this Section is deemed to have displaced White, which likely was the intent. See the Official Comments to this Section. This Section is based on the requirement that the claim be unliquidated and subject to a bona fide dispute. Accepting the instrument for less than the full amount under these circumstance provides consideration for a new agreement which modifies the previous agreement. If the claim is liquidated, there is no consideration, and thus no new agreement modifying the old agreement.
The current law requires intent and mutual assent to the new agreement, and the material facts must be known to both parties. See Saulsbury Oil Co. v. Phillips Petrol Co., 142 F.2d 27 (10th Cir. 1944), cert. denied, 323 U.S. 727(1944) . Under subsection (b), there is an irrebutable presumption that if the instrument contains a conspicuous statement to the effect it is tendered in full satisfaction of the claim, and if the payee negotiates the instrument and receives payment, there is mutual assent.
2. Under subsection (c), the result of subsection (b) does not apply to organizations if certain specified procedures are followed. Organizations have the tendency to handle numerous transactions and have less opportunity to review conspicuous statements on the instrument.
3. Even if there is a statement on the instrument that it is being presented in full payment the presentation of the instrument for payment will not cause an accord and satisfaction under Section 3-311 if the amount of the claim is liquidated. See Metropolitan Life Ins. Co. v. Richter, 173 Okla. 489, 49 P.2d 94 (Okla. 1935) Polin v. American Petrofina Co., 589 P.2d 240 (Okla. Ct. App. 1978).
4. The provisions of sub section 3-311(c) are not the exclusive methods for preventing the payment of a check constituting an accord and satisfaction. This Section, like most sections of Article 3, may be varied by agreement. See UCC § 1-102. The parties may establish by agreement the procedures for effecting an accord and satisfaction. The agreement may, for example, prohibit the use of a conspicuous statement to accomplish an accord and satisfaction entirely. If the handing of such instruments has been addressed in an agreement, then neither the "conspicuous notice" of subsection (c)(l) nor the return of the instrument under subsection (c)(2) would be necessary to prevent an accord and satisfaction.
