Okla. Stat. tit. 16, § 16-72: Title subject to certain interests and defects

Such marketable record title shall be subject to:

(a) All interests and defects which are inherent in the

muniments of which such chain of record title is formed; provided,

however, that a general reference in such muniments, or any of them,

to interests created prior to the root of title shall not be

sufficient to preserve them, unless specific identification be made

therein of a recorded title transaction which creates such interest.

(b) All interests preserved by the filing of proper notice or

by possession by the same owner continuously for a period of thirty

(30) years or more, in accordance with Section 74 of this title.

(c) The rights of any person arising from a period of adverse

possession or user, which was in whole or in part subsequent to the

effective date of the root of title.

(d) Any interest relating to a title transaction which has been

recorded subsequent to the effective date of the root of title from

which the unbroken chain of title of record is started; provided,

however, that such recording shall not revive or give validity to

any interest which has been extinguished prior to the time of the

recording by the operation of Section 73 of this title.

(e) The exceptions stated in Section 76 of this title as to

rights of reversioners in leases, as to severed mineral or royalty

interests, as to easements and interests in the nature of easements,

and rights granted, reserved or excepted by instruments creating

such easements or interests, or restrictions or agreements which are

part of a subdivision development plan, and as to interests of the

United States.
