Okla. Stat. tit. 18, § 18-491: Agreement between principal and surety for deposit of

monies and assets.

It shall be lawful for any party of whom a bond, undertaking or

other obligation is required, to agree with his surety or sureties

for the deposit of any or all monies and assets for which he and his

surety or sureties are or may be held responsible, with a bank,

savings bank, safe-deposit or trust company, authorized by law to do

business as such, or with other depository approved by a court or a

judge thereof, if such deposit is otherwise proper, for the

safekeeping thereof, and in such manner as to prevent the withdrawal

of such money or assets or any part thereof, without the written

consent of such surety or sureties, or an order of court, or a judge

thereof made on such notice to such surety or sureties as such court

or judge may direct; provided, however, that such agreement shall

not in any manner release from or change the liability of the

principal or sureties as established by the terms of the said bond.
