How to Make a Valid Ohio Will
Ohio Revised Code §§ 2107.02 through 2107.06

§ 2107.02 Who may make will.

A person who is eighteen years of age or older, of sound mind and memory, and not under restraint may make a will.

§ 2107.03 Method of making will.

Except oral wills, every will shall be in writing, but may be handwritten or typewritten. The will shall be signed at the end by the testator or by some other person in the testator's conscious presence and at the testator's express direction. The will shall be attested and subscribed in the conscious presence of the testator, by two or more competent witnesses, who saw the testator subscribe, or heard the testator acknowledge the testator's signature.

For purposes of this section, "conscious presence" means within the range of any of the testator's senses, excluding the sense of sight or sound that is sensed by telephonic, electronic, or other distant communication.

§ 2107.04 Agreement to make a will.

No agreement to make a will or to make a devise or bequest by will shall be enforceable unless it is in writing. The agreement shall be signed by the maker or by some other person at the maker's express direction. If signed by a person other than the maker, the instrument shall be subscribed by two or more competent witnesses who heard the maker acknowledge that it was signed at the maker's direction.

§ 2107.05 Incorporation by reference.

An existing document, book, record, or memorandum may be incorporated in a will by reference, if referred to as being in existence at the time the will is executed. That document, book, record, or memorandum shall be deposited in the probate court when the will is probated or within thirty days after the will is probated, unless the court grants an extension of time for good cause shown. A copy may be substituted for the original document, book, record, or memorandum if the copy is certified to be correct by a person authorized to take acknowledgments.

§ 2107.06 Age requirement for witnessing will.

No person under eighteen years of age shall witness a will executed pursuant to section 2107.03 of the Revised Code or an agreement to make a will or to make a devise or bequest by will pursuant to section 2107.04 of the Revised Code.
