Ohio Revised Code Title XXI. Courts Probate Juvenile § 2109.24

The probate court at any time may accept the resignation of any fiduciary upon the fiduciary's proper accounting, if the fiduciary was appointed by, is under the control of, or is accountable to the court. The fiduciary may resign by filing a written statement with the court after giving at least fifteen days notice to the persons known to be interested in the estate. Upon notice or a motion of the fiduciary to resign, the court may set the matter for a hearing and may notify all interested persons. No fiduciary shall resign without an order of the court.

If a fiduciary fails to make and file an inventory as required by sections 2109.58, 2111.14, and 2115.02 of the Revised Code or to render a just and true account of the fiduciary's administration at the times required by section 2109.301, 2109.302, or 2109.303 of the Revised Code, and if the failure continues for thirty days after the fiduciary has been notified by the court of the expiration of the relevant time, the fiduciary may be removed by the court and shall receive no allowance for the fiduciary's services unless the court enters upon its journal its findings that the delay was necessary and reasonable.

The court may remove any fiduciary, after giving the fiduciary not less than ten days' notice, for habitual drunkenness, neglect of duty, incompetency, or fraudulent conduct, because the interest of the property, testamentary trust, or estate that the fiduciary is responsible for administering demands it, or for any other cause authorized by law.

The court may remove a testamentary trustee upon the written application of more than one-half of the persons having an interest in the estate controlled by the testamentary trustee, but the testamentary trustee is not to be considered as a person having an interest in the estate under the proceedings; except that no testamentary trustee appointed under a will shall be removed upon the written application unless for a good cause.

Upon the resignation or removal of the fiduciary, the court shall revoke all letters of authority for the fiduciary.
