Ohio Revised Code Title XXI. Courts Probate Juvenile § 2107.60

An oral will, made in the last sickness, shall be valid in respect to personal property if reduced to writing and subscribed by two competent disinterested witnesses within ten days after the speaking of the testamentary words. The witnesses shall prove that the testator was of sound mind and memory, not under restraint, and that the testator called upon some person present at the time the testamentary words were spoken to bear testimony to the disposition as the testator's will.

No oral will shall be admitted to record unless it is offered for probate within three months after the death of the testator.
