Okla. Stat. tit. 6, § 6-910.8: Creditor process enforceability against bank

A. Subject to subsection B of this section, creditor process

with respect to a special deposit is not enforceable against the

bank holding the special deposit.

B. Creditor process is enforceable against the bank holding a

special deposit with respect to an amount the bank is obligated to

pay a beneficiary or a depositor if the process:

1. Is served on the bank;

2. Provides sufficient information to permit the bank to

identify the depositor or the beneficiary from the bank’s book and

records; and

3. Gives the bank a reasonable opportunity to act on the

process.

C. Creditor process served on a bank before it is enforceable

against the bank under subsection B of this section does not create

a right of the creditor against the bank or a duty of the bank to

the creditor. Other law determines whether creditor process creates

a lien enforceable against the beneficiary on a contingent interest

of a beneficiary, including a depositor as a beneficiary, even if

not enforceable against the bank.
