Ohio Revised Code Title LVIII. Trusts § 5817.13

(A) After a declaration of a trust's validity under division (B)(1) of section 5817.10 of the Revised Code, the trust may be modified, terminated, revoked, or reformed under sections 5804.10 to 5804.16 of the Revised Code, or other applicable law.

(B) The modification, termination, revocation, or reformation by a new trust or other document of a trust that has been declared valid under division (B)(1) of section 5817.10 of the Revised Code does not affect the trust or the prior declaration of its validity if the later trust or other document is found by a court of competent jurisdiction to be invalid due to the settlor's lack of capacity, or undue influence, restraint, or duress on the settlor, or otherwise.

(C) An amendment of a trust that has been declared valid under division (B)(1) of section 5817.10 of the Revised Code does not affect the trust or the prior declaration of its validity except as provided by the amendment. However, the amendment is not considered validated under this chapter unless its validity is also declared as provided in this chapter.
