Self-Proving Affidavit for Wills Requirements in Oklahoma

At a glance

Requirements one by one

Availability and governing law

Oklahoma offers two paper routes under 84 O.S. § 55(5): a sworn officer route and a no-officer written-declaration route. Both apply to an ordinary witnessed will and to a codicil, including a codicil to a holographic will. The section excludes the holographic or nuncupative will itself from self-proof.

Section 907 supplies a separate self-proof procedure for an electronic will.

Who signs or swears

Each route uses the testator and both attesting witnesses. In the officer route, the testator acknowledges and the witnesses give affidavits after all are sworn. In the written-declaration route, the testator and witnesses make and sign their declarations under penalty of perjury. The electronic form again uses the testator's acknowledgment and both witnesses' affidavits.

When it may be made

A paper will may be self-proved at execution or on a later date, but only during the lifetimes of the testator and the witnesses. Section 907 authorizes an electronic will to be simultaneously executed, attested, and made self-proving; it states no later electronic route.

Officer, oath and seal

Paper route (a) uses an officer authorized under Oklahoma law both to take deed acknowledgments and administer oaths. The officer's certificate must carry the official seal. Paper route (b) dispenses with the officer and seal by using signed declarations under penalty of perjury.

Electronic self-proof uses an officer authorized to administer oaths under the law of the execution state or an officer acting under the Oklahoma Remote Online Notary Act. The certificate and official seal must be affixed or logically associated with the electronic will.

Required recitals and form

Substantial compliance with the statutory forms is enough. The paper forms cover the instrument's identity as the will or codicil, willing execution as a free and voluntary act, the witnesses' signatures at the testator's request and in the testator's presence, and the testator's age of at least 18 and sound mind.

The electronic form adds that the testator and witnesses were under no constraint or undue influence and records each signer's city and state.

Attachment to the will

For paper route (a), the sealed officer certificate is attached or annexed to the testamentary instrument; both statutory forms refer to the annexed or foregoing instrument. For an electronic will, the sealed certificate and affidavits are affixed or logically associated. Under § 908, a certified paper copy of a self-proved electronic will must include the affidavits.

Electronic, remote and out-of-state rules

Section 907 expressly supports physical or electronic presence and Oklahoma remote online notarization. It also permits an oath officer authorized by the law of the state where execution occurs. The paper statute states no blanket rule automatically recognizing another state's self-proving form.

Probate effect and exceptions

Section 55(7) directs admission without any subscribing witness's testimony unless the instrument is contested. It then says the self-proved instrument is otherwise treated no differently: it may still be contested, revoked, or amended by codicil in the same way as an instrument that is not self-proved.

If there is no affidavit

For an uncontested will, 58 O.S. § 30 permits admission on the testimony or an affidavit made after filing from one subscribing witness. The court must be satisfied that the witness establishes every required execution particular and the testator's sound mind at execution.

What trips people up

The no-notary form is a separate statutory route

A paper will does not always need the officer affidavit to become self-proved. Section 55(5)(b) separately authorizes substantially statutory written declarations signed by the testator and witnesses under penalty of perjury.

Later paper self-proof has a lifetime cutoff

The delayed paper route disappears once the testator or a required witness has died. Electronic self-proof is narrower still because § 907 only states a simultaneous execution-time procedure.

Common questions

Can a codicil to a holographic will be made self-proving?

Yes. Although § 55(5) excludes the holographic will itself, it expressly includes “every codicil” to a holographic will in the paper self-proof procedure.

What happens if a witness signs the no-notary declaration falsely?

Current § 55(6) makes a knowingly false witness declaration or fraudulent identity misrepresentation a perjury offense classified as a Class D1 felony when the section's intent requirement is met.
