Okla. Stat. tit. 11, § 11-36-221: Collection of payments - Bond of clerk - Special fund

The municipal clerk shall be required to execute a good and

sufficient bond, with sureties, and in an amount to be approved by

the governing body, payable to the municipality, conditioned for the

faithful performance of the duties conferred upon the clerk as

collector of the assessments.

The municipal clerk shall keep an accurate account of all

assessment collections made by him, and shall pay to the municipal

treasurer daily the amounts of the assessments collected by him. The

amounts so collected and paid to the municipal treasurer shall

constitute a separate, special fund to be used and applied to the

payment of the bonds and interest coupons which are issued against

the assessments. After the payment of all bonds and interest

thereon, any surplus remaining in the fund shall be used for the

purpose of repairing and maintaining any improvement for which

assessments have been levied, and for no other purpose whatsoever.
