Ohio Rev. Code Ann. § 2109.27

When two or more fiduciaries have been appointed jointly to execute a trust and one or more of them dies, declines, resigns, or is removed, the title shall pass to the remaining fiduciaries who shall execute the trust, unless the creating instrument expresses a contrary intention or unless the probate court on the application of persons interested in the trust determines otherwise. The remaining fiduciaries shall within ninety days after the death, resignation, or removal of a cofiduciary, file in the court a complete account covering all matters to the time of such death, resignation, or removal.
