Okla. Stat. tit. 68, § 231.2

Upon a final determination by a court of competent jurisdiction that a tax levied or collected by the state is delinquent, the Oklahoma Tax Commission may issue an order attaching the assets, up to the amount of tax liability, of any bank accounts maintained within this state by the delinquent taxpayer. The Tax Commission shall mail a certified copy of the attachment order to the banks in which the accounts are maintained. Upon receipt of such order the banks shall be liable to the Tax Commission in an amount equal to any attached funds released from the accounts without the written permission of the Tax Commission. The Tax Commission may release funds from the accounts to effectuate payment of the tax liability or to protect the interests of the state and shall release the account within thirty (30) days of full payment of the tax liability.
