Okla. Stat. tit. 62 § 396
The clerk of every county, city, town, township, school district and board of education, issuing bonds under Sections 391 et seq. of this title shall register the same in his office. Such bonds shall also, in every case, be registered by the county clerk, showing the date, number and amount thereof, rate of interest, to whom payable, where payable, date of maturity, and, if optional, under what conditions; and all indebtedness refunded under this article shall have the words "paid in full" marked in a plain manner across the face of each bond, or warrant refunded; and such canceled obligations shall be carefully preserved in the office of the county clerk or destroyed by the county commissioners, a register of the number, amount and date of issue having been first made by the county clerk. The proper officer shall, at the time of issuing refunding bonds, make out and transfer to the State Auditor and Inspector a certified statement of all proceedings had by the proper board or city council as shown of record and that said bonds have been issued for value in all respects in conformity to this article for certain indebtedness to be surrendered, definitely describing the bonds issued and the indebtedness to be surrendered, in exchange therefor and that they have been duly registered by the attesting clerk and the county clerk as required herein; which statement shall be in such form and include such other information as the State Auditor and Inspector may require, and be signed by all the officers whose signatures are attached to such bonds, and attested by the proper clerk, with the corporate seal of the county, city, town, township, school district or board of education, if any, and duly acknowledged before the county clerk. And the State Auditor and Inspector shall, upon being satisfied that such bonds have been issued according to the provisions of this article, and that the signatures thereto of the officers signing the same are genuine, register the same in his office in a book kept for that purpose and shall, under his seal of office, certify upon such bonds the fact that they have been registered in his office according to law. Nothing in Sections 391 et seq. of this title shall be construed to prohibit options available under the Registered Public Obligations Act of Oklahoma.
