Ohio Rev. Code § 1313.41
If the assignor or a creditor files in the probate court a written requisition on the assignee or trustee for the benefit of creditors to disallow any claims presented which he has not reported as disallowed, and enters into bond to said assignee or trustee in such amount and with such sureties as the court approves, conditioned to pay all the costs and expenses of contesting them by the order of the court, such claims shall be disallowed, although theretofore allowed by the assignee or trustee. The assignee or trustee must forthwith give written notice thereof to the creditors, or their attorneys, whose claims are so disallowed. Thereupon the same proceedings shall be had as required in other cases of disallowance under sections 1313.39 and 1313.40 of the Revised Code.
