Ohio Revised Code Title XXI. Courts Probate Juvenile § 2109.34

If an interest in an estate or trust is or may be possessed by persons who will compose a certain class upon the happening of any future event, the unborn members of that class shall be considered to be represented in any hearing upon a fiduciary's account required by section 2109.32 of the Revised Code, if any living member of the class is made a party to that proceeding or if a trustee for the proceeding is appointed by the probate court. The unborn members of the class need not be served by publication. An order made in the proceeding shall be binding upon all members of the class, except that the order may be vacated for fraud as provided in section 2109.35 of the Revised Code.

If the beneficiaries, both present and future, of a charitable trust are not represented by a trustee or an existing corporation or other organization, they shall be represented in any proceeding under this section by the attorney general if the attorney general is made a party to the proceeding. Any order made in the proceeding shall be binding upon those beneficiaries, except for fraud.
