Ohio Will Requirements at a Glance
Here are the exact Ohio estate planning rules for making a valid will:
| Minimum age to make a will | 18 |
| Witnesses required | 2 |
| Notarization required | NO — Ohio does not require notarization for a valid will. However, notarization may be used if the testator and witnesses sign affidavits before a notary, though Ohio does not formally recognize the self-proving affidavit process that most other states use. |
| Handwritten (holographic) will allowed | NO — Ohio does not recognize holographic (unwitnessed handwritten) wills. A will may be handwritten or typewritten under ORC 2107.03, but it still must be signed by the testator and attested by two competent witnesses. However, under ORC 2107.24 (the “harmless error” doctrine), a probate court may treat a document as a valid will by clear and convincing evidence even if it does not fully comply with execution formalities — but this is discretionary and not guaranteed. |
| Self-proving affidavit available | NO — Ohio is one of the few states that does not provide a self-proving affidavit procedure. Witnesses may need to testify or provide proof of the will’s validity at probate. The probate court has discretion under ORC 2107.18 to require witness testimony or may admit the will based on what appears on its face. |
| Statutory will form | NO — Ohio does not offer an official state-provided statutory fill-in-the-blank will form. The Supreme Court of Ohio provides probate administration forms (such as the Application to Probate Will) at supremecourt.ohio.gov, but not a form for creating a will itself. You may wish to consult a licensed attorney or use a reputable legal service. |
What an Ohio Will Does (and Doesn’t Do)
In Ohio, a valid will may name an executor (called a “fiduciary” in Ohio) to manage the estate through probate, name a guardian for minor children, direct how probate assets are distributed among beneficiaries, make specific bequests of personal property or real estate, and establish testamentary trusts.
What an Ohio will does NOT control: An Ohio will does not control assets that pass outside of probate, including life insurance proceeds with a named beneficiary, retirement accounts (401k, IRA) with designated beneficiaries, jointly held property with survivorship rights, payable-on-death (POD) or transfer-on-death (TOD) bank and brokerage accounts, and assets already held in a living trust.
Oral wills in Ohio: YES with narrow conditions — under ORC 2107.60, an oral (nuncupative) will is valid only for personal property (not real estate), must be made during the testator’s last sickness, must be reduced to writing and subscribed by two competent disinterested witnesses within 10 days of the testamentary words being spoken, the testator must have called upon someone present to bear testimony, and the oral will must be offered for probate within 3 months of the testator’s death.
How to Update or Revoke an Ohio Will
Under ORC 2107.33, an Ohio will may be amended by executing a codicil, which is a written supplement that must be signed and witnessed under the same formalities as the original will (two competent witnesses). A will may be revoked by: (1) tearing, canceling, obliterating, or destroying it with the intent to revoke, (2) having another person destroy it at the testator’s request and in their conscious presence, (3) having another person destroy it pursuant to the testator’s express written direction, or (4) executing a later will or codicil that revokes the prior one.
The testator must have the same legal capacity required to make a will in order to revoke one. If a will has been deposited with a probate court, a petition must be filed to revoke it.

Other Ohio will-making rules: Ohio uses a “conscious presence” standard for witnessing under ORC 2107.03 — witnesses must be within the range of any of the testator’s senses, but this specifically excludes sight or sound transmitted by telephonic, electronic, or other distant communication (with an exception for remote witnessing enacted by Senate Bill 131, effective June 2023, which permits real-time audiovisual witnessing if all parties are physically located in Ohio).
Ohio also has an interested-witness rule: if one of the two required witnesses is a beneficiary under the will, that witness’s bequest is void and they receive only what they would have inherited under intestacy.
Additionally, Ohio follows the “harmless error” doctrine under ORC 2107.24, allowing a probate court to treat a noncompliant document as a valid will if clear and convincing evidence shows the decedent prepared it, signed it, and intended it to be their will.

Make sure your coverage and beneficiaries are current so your plan does what you intend.
Understanding Ohio Estate Planning
Getting started with Ohio estate planning is the single best gift you can give your family. A valid Ohio will lets you decide who inherits, name an executor, and name a guardian for your children — instead of leaving it to a default state formula.
When people look into Ohio estate planning, the answer comes down to the state’s execution rules: your age, the number of witnesses, and whether you make it self-proving.
If any part of Ohio estate planning is unclear, your state court’s self-help center can point you to the official forms.
