Ohio Rev. Code Ann. § 5905.12

If any guardian fails to file with the probate court any account as required by section 5905.11 of the Revised Code, or by an order of the court, when any account is due, or within thirty days after citation issues as provided by section 2109.31 of the Revised Code, or fails to furnish the veterans' administration a true copy of any account, petition, or pleading as required by sections 5905.01 to 5905.19, inclusive, of the Revised Code, the court may remove such guardian for such failure.
