Okla. Stat. tit. 19 § 866.13
From and after the adoption of a plan for major streets or highways as a part of the comprehensive plan for the physical development of the area and the adoption of the rules and regulations governing subdivision of land no plat or deed or other instrument of a subdivision of land within the area shall be accepted for record in the office of the county clerk until it shall have been approved by such commission as being in accordance with the officially adopted rules and regulations of the commission and such approval endorsed in writing on the plat.
The approval of the commission required by this section or the refusal to approve shall take place within forty-five (45) days from and after the submission of the subdivision of land for final approval; otherwise said subdivision of land shall be deemed to have been approved and the certificate of said commission as to the date of the submission of the subdivision of land for approval and as to the failure to take action thereon within such time shall be sufficient in lieu of the written endorsement or evidence of approval herein required. The ground of refusal of any subdivision of land submitted, including citation to or reference to the rules or regulations violated by the subdivision of land shall be stated upon the record of the commission.
Whoever, being the owner or agent of the owner of any land within the area, transfers or sells or agrees to sell, or negotiates to sell any land by reference to or exhibition thereof, or by other use of a plat of a subdivision or a contract for deed or other instrument before such plat or deed or instrument has been approved by the commission and filed of record in the office of the county clerk, or whoever, being the owner or agent of the owner of a parcel of ground, transfers, or sells or agrees to sell, or negotiates to sell any tract of land of less than ten (10) acres, except in counties adjoining a county having a cooperative planning commission formed under the provisions of 19 O.S. 1961, Section 863.2, in which case upon order or rule of the city-county cooperative planning commission a tract of less than two and one-half (2 1/2) acres where such tract was not shown of record in the office of the county clerk as separately owned at the effective date of the regulations hereinafter provided for and not located within a subdivision approved according to law and filed of record in the office of the county clerk, or if so located, not comprising at least one entire lot as recorded, without first obtaining the written approval of the commission by its endorsement on the instrument of transfer, or contract of sale or other agreement to transfer, shall be subject to the penalties by this act provided; and such transaction shall be unlawful and shall not be recorded by the county clerk; provided that a tract of land which has not been subdivided, a tract of more than ten (10) acres, except in counties adjoining a county having a cooperative planning commission formed under the provisions of 19 O.S. 1961, Section 863.2, in which case upon order or rule of the city-county cooperative planning commission a tract of more than two and one-half (2 1/2) acres, may be transferred by the owner thereof to any person without complying with the provisions of this act and such transfer shall be duly recorded by the county clerk; and provided, further, that such person may further transfer such tract without complying with the provisions of this act, so long as such transfer involves the whole of such tract and the transfer shall be recorded by the county clerk, and thereafter any transfer shall be subject to existing law. Provided further, all deeds of record as of January 1, 1963, which convey tracts of land not portions of an approved or disapproved plat or subdivision, are hereby validated insofar as the filings of the same are concerned, whether or not first approved by the commission.
In its consideration of such transfers, referred to as "lot-splits" the commission shall apply the same regulations as are applied to subdivisions in order to accomplish the purpose of planning as herein provided. No city board of adjustment or county board of adjustment or any office representing such boards shall require that easements be given to the city or county for major street usages serving approval on a lot-split deed, and approving such deeds shall not be deemed consideration for the transfer of easements for road purposes, except in the case of streets platted and dedicated by the owner in approved subdivision plans.
