Okla. Stat. tit. 62 § 475
It is hereby made the duty of the treasurer of the county, city, or town to whom a warrant, certificate of indebtedness or bond is directed for payment, to register the same by entering the number, the date, the name of the payee, the fund upon which it is drawn and the amount, and by writing on the warrant or evidence of indebtedness, the date of registration, his name and official title. All warrants, certificates of indebtedness or bonds, shall be registered in the order in which they have been issued, and when so registered shall be returned to the clerk of the county, city or town. No warrant, certificate of indebtedness or bond shall be a valid charge until registered by the treasurer of the municipality issuing the same as herein provided. Nothing herein shall prevent the appointment and compensation from time to time by the governing body of any county, city, or town of a registrar or transfer agent to effect the transfer of ownership or change of payee of any certificate of indebtedness or bonds issued by such county, city, or town and to maintain books and records relating thereto. Nothing in this section shall prohibit any governing board from using automated recordkeeping procedures or methods and recording different information in lieu of the information specified in this section, provided the information required in this section can be accessed. Warrants and all evidences of indebtedness shall draw a rate of interest to be fixed by the governing board not to exceed the maximum rate provided by Section 498.1 of this title from and after its registration by the treasurer, unless there is cash on hand to pay the same when presented for registration and then the treasurer shall make the same "payable" after registering the same, and no interest shall be computed or allowed thereon when paid. When the treasurer has money on hand to pay warrants duly registered, the treasurer shall publish notice thereof in one issue of a newspaper, or by posting five notices in public places, and interest shall cease on the warrants after thirty (30) days from the date of the publication or posting of said notice.
