Okla. Stat. tit. 18, § 18-381.47: Notice and payment of withdrawals

With respect to deposit accounts, an association may require

such minimum advance notice of withdrawal as is specified by federal

regulations or such longer advance notice period of not more than

thirty (30) days as its bylaws may provide. The payment of

withdrawals from deposit accounts, in the event an association does

not have funds available to pay all withdrawals when due, shall be

subject to such rules and procedures as may be prescribed by the

State Banking Commissioner, but any association which, except as

authorized in writing by the Commissioner, fails to make full

payment of any withdrawal when due shall be deemed to be in an

unsafe or unsound condition to transact business within the meaning

of Section 381.74 of this title.
