Okla. Stat. tit. 6, § 6-910.11: Duties of bank

A. A bank does not have a fiduciary duty to any person with

respect to a special deposit.

B. When the bank holding a special deposit becomes obligated to

pay a beneficiary, a debtor-creditor relationship arises between the

bank and beneficiary.

C. The bank holding a special deposit has a duty to a

beneficiary to comply with the account agreement and this act.

D. If the bank holding a special deposit does not comply with

the account agreement or this act, the bank is liable to a depositor

or beneficiary only for damages proximately caused by the

noncompliance. Except as provided by other law of this state, the

bank is not liable for consequential, special, or punitive damages.

E. The bank holding a special deposit may rely on records

presented in compliance with the account agreement to determine

whether the bank is obligated to pay a beneficiary.

F. If the account agreement requires payment on presentation of

a record, the bank shall determine within a reasonable amount of

time whether the record is sufficient to require payment. If the

agreement requires action by the bank on presentation of a record,

the bank is not liable for relying in good faith on the genuineness

of the record if the record appears on its face to be genuine.

G. Unless the account agreement provides otherwise, the bank is

not required to determine whether a permissible purpose stated in

the agreement continues to exist.
