Oklahoma Will Requirements at a Glance
Here are the exact rules for making a valid will in Oklahoma:
| Minimum age to make a will | 18 |
| Witnesses required | 2 |
| Notarization required | NO — notarization is not required for a will to be valid in Oklahoma. However, notarization is needed if the testator wants to attach a self-proving affidavit under 84 O.S. § 55, which allows the will to be admitted to probate without live witness testimony. |
| Handwritten (holographic) will allowed | YES — Oklahoma recognizes holographic wills under 84 O.S. § 54. The will must be entirely written, dated, and signed in the testator’s own handwriting. No witnesses are required for a holographic will. The original document must be presented at probate — copies are not sufficient. |
| Self-proving affidavit available | YES — under 84 O.S. § 55, any will (other than a holographic or nuncupative will) and any codicil may be made self-proving at the time of execution or at any later date during the lifetimes of the testator and witnesses. The testator and the attesting witnesses must sign a sworn affidavit before an officer authorized to administer oaths (typically a notary public), and the certificate is attached to or affixed to the will. A self-proved will may be admitted to probate without the testimony of any subscribing witness, unless the will is contested. |
| Statutory will form | NO — Oklahoma does not provide an official statutory fill-in-the-blank will form. The state sets requirements for a valid will (84 O.S. § 55) but does not mandate or offer a specific statutory form. Oklahoma Legal Aid Services (oklaw.org) provides general guidance on making your own will. |
What a Oklahoma Will Does (and Doesn’t Do)
A valid Oklahoma will may name a personal representative (executor) to administer the estate, name a guardian for minor children, direct how probate assets are distributed among beneficiaries, create testamentary trusts, make specific bequests of personal property and real estate, and express wishes regarding burial or cremation.
What a Oklahoma will does NOT control: An Oklahoma will does not control assets that pass outside of probate, including life insurance proceeds with a named beneficiary, retirement accounts (401(k), IRA) with a named beneficiary, payable-on-death (POD) or transfer-on-death (TOD) bank and brokerage accounts, property held in joint tenancy with right of survivorship, and assets already placed in a living trust.
Oral wills in Oklahoma: YES — Oklahoma recognizes nuncupative (oral) wills under 84 O.S. § 46, but only under very narrow conditions: (1) the testator must be in actual military service in the field or doing duty on shipboard at sea, AND in actual contemplation, fear, or peril of death, or must be in expectation of immediate death from an injury received the same day;
(2) the estate bequeathed may not exceed 1000 in value; and (3) the oral declaration must be made before two witnesses.
How to Update or Revoke a Oklahoma Will
An Oklahoma will may be amended by executing a codicil, which must meet the same formalities as the original will (written, signed by the testator, attested by two witnesses) under 84 O.S. § 57. A codicil republishes the original will as modified.

A will may be revoked entirely by (1) executing a new will or written instrument declaring the revocation, executed with the same formalities as a will, or (2) by the testator or someone acting in the testator’s presence and at the testator’s direction burning, tearing, canceling, obliterating, or destroying the will with the intent to revoke it, under 84 O.S. § 101. Revoking a will also revokes all its codicils.
Other Oklahoma will-making rules: Oklahoma requires that the testator’s subscription (signature) appear at the end of the will. Witnesses must also sign at the end of the will, at the testator’s request and in the testator’s presence. Holographic wills must be entirely in the testator’s handwriting — any typed or printed text may invalidate the document.
If a will is destroyed by someone other than the testator, the testator’s direction and the fact of destruction must be proved by two witnesses under 84 O.S. § 101. Oklahoma also recognizes wills executed in other states or countries if valid under the laws of the place of execution.

Understanding Oklahoma Estate Planning
Getting started with Oklahoma estate planning is the single best gift you can give your family. A valid Oklahoma 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 Oklahoma estate planning, the real 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 Oklahoma estate planning is unclear, your state court’s self-help center can point you to the official forms and resources.
