Ohio Rev. Code § 2107.181
If it appears that the instrument purporting to be a will is not entitled to admission to probate, the court shall enter an interlocutory order denying probate of the instrument, and shall continue the matter for further hearing. The court shall order that not less than ten days' notice of the further hearing be given by the applicant, the executor named in the instrument, the persons holding a power to nominate an executor as described in section 2107.65 of the Revised Code, or a commissioner appointed by the court, to all persons named in the instrument as legatees, devisees, beneficiaries of a trust, trustees, executors, or persons holding a power to nominate an executor, coexecutor, successor executor, or successor coexecutor as described in section 2107.65 of the Revised Code. Upon further hearing, witnesses may be called, subpoenaed, examined, and cross-examined in open court or by deposition, and their testimony reduced to writing and filed in the same manner as in hearings for the admission of wills to probate. Thereupon, the court shall revoke its interlocutory order denying probate to the instrument, and admit it to probate, or enter a final order refusing to probate it. A final order refusing to probate the instrument may be reviewed on appeal.
