Okla. Stat. tit. 60, § 60-1606.2: Settlor's powers — Power of withdrawal

A. To the extent a trust is revocable by a settlor, a trustee

may follow a direction of the settlor that is contrary to the terms

of the trust. To the extent a trust is revocable by a settlor in

conjunction with a person other than a trustee or person holding an

adverse interest, the trustee may follow a direction from the

settlor and the other person holding the power to revoke even if the

direction is contrary to the terms of the trust.

B. To the extent a trust is revocable and the settlor has

capacity to revoke the trust, rights of the beneficiaries are

subject to the control of, and the duties of the trustee are owed

exclusively to, the settlor.

C. During the period the power may be exercised, the holder of

a power of withdrawal has the rights of a settlor of a revocable

trust under this section to the extent of the property subject to

the power.
