Ohio Revised Code Title LVIII. Trusts § 5806.02

(A) Unless the terms of a trust expressly provide that the trust is irrevocable, the settlor may revoke or amend the trust. This division does not apply to a trust created under an instrument executed before January 1, 2007.

(B) If a revocable trust is created or funded by more than one settlor, all of the following apply:

(C) The settlor may revoke or amend a revocable trust by substantial compliance with a method provided in the terms of the trust or, if the terms of the trust do not provide a method, by any method manifesting clear and convincing evidence of the settlor's intent, provided that a revocable trust may not be revoked or amended by a will or codicil, regardless of whether it refers to the trust or specifically devises property that would otherwise have passed according to the terms of the trust unless the terms of the trust expressly allow it to be revoked or amended by a will or codicil.

(D) Upon revocation of a revocable trust, the trustee shall deliver the trust property as the settlor directs.

(E) An agent under a power of attorney may exercise a settlor's powers with respect to revocation, amendment, or distribution of trust property only to the extent expressly authorized by both the terms of the trust and the power.

(F) A guardian of the estate of the settlor or, if no guardian of the estate has been appointed, a guardian of the person of the settlor may exercise a settlor's powers with respect to revocation, amendment, or distribution of trust property only with the approval of the court supervising the guardianship.

(G) A trustee who does not know that a trust has been revoked or amended is not liable to the settlor or settlor's successors in interest for distributions made and other actions taken on the assumption that the trust had not been amended or revoked.
