Ohio Rev. Code § 2113.05: Letters testamentary shall issue.

When a will is approved and allowed, the probate court shall issue letters testamentary to the executor named in the will or to the executor nominated by holders of a power as described in section 2107.65 of the Revised Code, or to the executor named in the will and to a coexecutor nominated by holders of that power, if the executor or coexecutor is suitable, competent, accepts the appointment, and gives bond if that is required.

If no executor is named in a will and no power as described in section 2107.65 of the Revised Code is conferred in the will, or if the executor named in a will or nominated pursuant to that power dies, fails to accept the appointment, resigns, or is otherwise disqualified and the holders of the power do not have authority to nominate another executor or the power is not conferred in the will, or if the power is conferred in a will but the power cannot be exercised because of the death of a holder of the power, letters of administration with the will annexed shall be granted to a suitable person or persons, named as devisees or legatees in the will, who would have been entitled to administer the estate if the decedent had died intestate, unless the will indicates an intention that the person or persons shall not be granted letters of administration. Otherwise, the court shall grant letters of administration with the will annexed to some other suitable person.
