Except as otherwise provided in subsection (c) of Section 1-9-340 of this title, and unless the bank otherwise agrees in a signed record, a bank's rights and duties with respect to a deposit account maintained with the bank are not terminated, suspended, or modified by:
Okla. Stat. tit. 12A, § 1-9-341
Oklahoma Code Comment
Section 9-341 is designed to ensure that security interests in deposit accounts will not interfere with bank deposit transactions or the bank payment system or other rules governing deposit accounts and will not otherwise "clog" the payments system. The rules of 9-341 are entirely new and are well described by the Official Comments. See also revised section 9-104 , and sections 9-330 B9-332, 9-340, and 9-342 .
