Okla. Stat. tit. 12A, § 3-310
Oklahoma Code Comment
1. Section 3-310 expands, but does not change, pre-revision Section 3-802 to cover situations in which an instrument other than a note or check is given for an obligation. Comparing prerevision Section 3-802 to this Section, sub sections 3-310(b)(1) and (b) ( 2) only deal with payment or certification. There are other ways to discharge an instrument, and any discharge on the instrument results in discharge of the underlying obligation Subsections (b)(l) and (b)(2) are too narrow and should not be regarded as exclusive, as there was no intent to change the law.
2. Under this Section, if a cashier's check or other similar check is taken for an obligation, the obligation is discharged. This does not, however, prevent suit against the obligor as an indorser of the check.
3. The holding of In re Hayman, 6 U.C.C. Rep. Serv. 928 (Bankr. W.D. Okla. 1969) is in accordance with subsection (b)(l). The court found that when payment of a personal check, accepted for a debt, was stopped, an action could be maintained on the original debt.
4. Subsection (b)(4) helps resolve the uncertain applicability of pre-revision Section 3-802 to cases where a check is stolen, the payee's signature is forged, and the forger obtains payment. In such instance, the obligation is suspended under subsection (b)(1), and the payee's cause of action is against the payor bank in conversion and against the drawer under Section 3-309 if the instrument is not available. See UCC § 3-309. If the instrument is available through legal process, such as replevin, the payee must obtain the instrument through legal process and sue on the instrument. The payee cannot sue the drawer on the underlying contract.
