Okla. Stat. tit. 68, § 68-2891: Homestead exemption - Forms

On or before January 1st of each year, the Oklahoma Tax

Commission shall prescribe suitable blank forms to be used by all

claimants for homestead exemption. Such forms shall contain

provisions for the showing of all information which the Oklahoma Tax

Commission may deem necessary to enable the proper county officials

to determine whether each claim for exemption should be allowed. It

shall be the duty of the county assessor of each county in this

state to furnish such forms, upon request, to each person desiring

to make application for homestead exemption on property located

within that county. The forms so prescribed shall be used uniformly

throughout the state and no application for exemption shall be

allowed unless the applicant uses the regularly prescribed form in

making his or her application.
