Okla. Stat. tit. 12A, § 12A-1-9-304: Law governing perfection and priority of security

interests in deposit accounts.

LAW GOVERNING PERFECTION AND PRIORITY OF

SECURITY INTERESTS IN DEPOSIT ACCOUNTS

(a) The local law of a bank's jurisdiction governs perfection,

the effect of perfection or nonperfection, and the priority of a

security interest in a deposit account maintained with that bank

even if the transaction does not bear any relation to the bank's

jurisdiction.

(b) The following rules determine a bank's jurisdiction for

purposes of this part:

(1) If an agreement between the bank and its customer governing

the deposit account expressly provides that a particular

jurisdiction is the bank's jurisdiction for purposes of this part,

this article, or the Uniform Commercial Code, that jurisdiction is

the bank's jurisdiction.

(2) If paragraph (1) of this subsection does not apply and an

agreement between the bank and its customer governing the deposit

account expressly provides that the agreement is governed by the law

of a particular jurisdiction, that jurisdiction is the bank's

jurisdiction.

(3) If neither paragraph (1) nor paragraph (2) of this

subsection applies and an agreement between the bank and its

customer governing the deposit account expressly provides that the

deposit account is maintained at an office in a particular

jurisdiction, that jurisdiction is the bank's jurisdiction.

(4) If none of the preceding paragraphs of this subsection

applies, the bank's jurisdiction is the jurisdiction in which the

office identified in an account statement as the office serving the

customer's account is located.

(5) If none of the preceding paragraphs applies, the bank's

jurisdiction is the jurisdiction in which the chief executive office

of the bank is located.
