Okla. Stat. tit. 58, § 58-1254: Revocation or change of grantee beneficiary - Effect of

will.

A. A designation of the grantee beneficiary may be revoked at

any time prior to the death of the record owner, by executing,

acknowledging and recording in the office of the county clerk in the

county where the real estate is located an instrument revoking the

designation. The signature, consent or agreement of or notice to

the grantee beneficiary or beneficiaries to the revocation is not

required.

in accordance with the Nontestamentary Transfer of Property Act may

not be revoked by the provisions of a will.
