Oklahoma recognizes attested wills and holographic wills

Oklahoma Statutes — Execution of Wills

Okla. Stat. tit. 84, § 55

What the rule says

Oklahoma provides two pathways to a valid will:

Attested wills (Okla. Stat. tit. 84, § 55)

A valid Oklahoma attested will requires:

1. A writing. 2. The testator's signature at the end of the will. 3. Two competent witnesses. Two witnesses must sign the will in the testator's presence.

Holographic wills (Okla. Stat. tit. 84, § 54)

An Oklahoma holographic will is valid if:

1. Entirely written, dated, and signed by the testator's hand. 2. The date is essential — without a date, the holographic will is invalid.

Oklahoma's holographic will requirement of a date matches Louisiana's olographic testament requirement and is stricter than some states' holographic frameworks.

Self-proving affidavits

Under Okla. Stat. tit. 84, § 55, a will accompanied by a self-proving affidavit can be admitted to probate without requiring witness testimony.

What you can do about it

For an Oklahoma attested will:

- Have the testator and at least two competent witnesses present. - Use the self-proving affidavit. - Sign at the end of the document. - Avoid using beneficiaries as witnesses.

For an Oklahoma holographic will:

- Write the entire substantive document in the testator's handwriting. - Date the document. This is critical — without a date, the holographic will fails. - Sign the document.

Who this affects most

Oklahoma's two-pathway framework provides flexibility through attested and holographic options. The required-date feature for holographic wills is a stricter requirement than many states.
