Okla. Admin. Code § 325:75-1-4
The breeder or owner of a horse that is eligible for participation in the Oklahoma-Bred Program may accredit such horse with the Oklahoma Horse Racing Commission by submitting a Commission-approved application, all required documents, and the appropriate fee to the official Registering Agency. Failure to submit either the required fee or a Commission-approved application will result in the immediate rejection of the application. Failure to complete the accreditation process of a racing stock by submitting all required documentation, including the original or replacement Certificate of Registration, to the Commission by December 31 of the horse's three-year-old year will result in the application being rejected with no refund of fee. Failure to complete the accreditation process of a broodmare or stallion by submitting all required documentation to the Commission within one (1) year from submitting the original application will result in the application being rejected with no refund of fee. In such event, a new application along with the necessary documentation and applicable fees must be submitted to the Commission in order to accredit the horse in the Oklahoma-Bred Program. The Commission may contract with and designate an official Registering Agency to implement the accreditation of Oklahoma-Bred horses. [3A:208.3(C)].
