Oklahoma: Petition to Probate a Will Requirements

Requirements one by one

District court, venue, petitioner, and petition contents

Oklahoma uses a district-court petition to prove the will. Under § 5, a
resident decedent's proceeding belongs in the county of residence at death.
For a nonresident, the statute gives first place to an Oklahoma county of death
where the decedent left an estate, then an estate county under its stated
fallbacks, and finally the Oklahoma county of death when the decedent left no
estate in the state.

Section 22 permits the named executor, a named devisee or legatee, or any
other interested person to petition at any time after death. Filing eligibility
is therefore broader than eligibility to receive letters as the will's executor.

The written petition must be signed by the applicant or counsel. 58 O.S. § 23
requires jurisdictional facts; the named executor's consent or renunciation;
the known names, ages, and residences of heirs, legatees, and devisees; the
estate's probable value and character; and the person for whom letters are
requested. The section does not require verification or notarization.

Paper, missing, and electronic wills

The petition route in § 22 is available whether the will is in the petitioner's
possession or not, is lost or destroyed, lies outside Oklahoma, is written, or
is nuncupative. That breadth does not erase the separate production duty:
§ 21 makes the will's custodian deliver it to the district court or the
named executor within 30 days after receiving information of the death.

Oklahoma also has an electronic-will route. Under 84 O.S. § 908, an
individual may certify under penalty of perjury that a paper copy is a complete,
true, and accurate copy of the electronic will. If the electronic will was
self-proved, the certified copy must include the self-proving affidavits.

Two different 30-day clocks

The custodian's § 21 delivery clock is not a universal petition deadline.
Section 22 says an authorized petitioner may file at any time after death.

A different consequence applies to the nominee. Under § 108, a named
executor who knows both of the death and the nomination but does not petition
for probate and letters for 30 days may be held to have renounced the right to
letters unless good cause explains the delay.

Proof depends on self-proving status and contest

For an uncontested non-self-proved will, § 30 permits the testimony or an
affidavit made after filing from one subscribing witness. The evidence must
satisfy the court that execution met the law and that the testator was of sound
mind.

A paper will self-proved under 84 O.S. § 55 is admitted without subscribing-
witness testimony unless contested. An electronic will may be executed,
attested, and made self-proving together under 84 O.S. § 907, with the
testator's acknowledgment, witness affidavits, and the authorized officer's
sealed certificate.

Hearing, notice, and objections

The hearing is mandatory. 58 O.S. § 25 requires the court to set it 10 to 30
days after filing. Notice is mailed at least 10 days before the hearing to the
required heirs, legatees, and devisees. If a required name or address is unknown,
or a described recipient survived the testator but died before filing and no
personal representative is known, notice is also published once in a newspaper.

58 O.S. § 26 additionally requires the same notice and proof for a named
executor who did not petition and for a known nonpetitioning coexecutor. Under
§ 28, the court ordinarily requires notice proof at the hearing before
hearing will testimony; an interested party's court appearance waives notice.
Any interested person may appear and contest under § 29.

Qualification, oath, local agent, bond, and letters

After the will is proved and allowed, § 101 directs letters to the named
executor who is competent, appears, and qualifies. 58 O.S. § 102 disqualifies
a minor, a person whose crime causes the court to withhold fiduciary trust, and
a person adjudged unable to perform because of drunkenness, improvidence, or
lack of understanding and integrity.

The executor must take the statutory oath before letters issue under § 161.
A nonresident executor must file a written appointment of a county-resident
process agent before acting under § 162.

Bond ordinarily precedes receipt of letters under § 171, although the court
may order no bond when the circumstances show none is necessary. If the will
expressly waives bond, § 178 permits letters without bond unless the court
requires one for good cause.

What trips people up

• The two 30-day periods belong to different people and have different
  effects. A custodian faces a delivery duty and damages; a named executor may
  lose appointment priority unless good cause supports the delay.
• A signed petition is not automatically a sworn petition. Section 23 says
  written and signed, but does not add a verification or notary requirement.
• Self-proof removes ordinary subscribing-witness testimony, not the hearing
  or the possibility of contest. Sections 25 and 29 still apply.
• An electronic will uses a certified-paper-copy route. Treating the case as
  though only an original paper will can be offered misses § 908.

Common questions

Does a formal defect in the petition automatically void probate?

No. Section 23 says a defect of form, or a defect in stating jurisdictional
facts that actually existed, does not make the probate void.

Must trust beneficiaries receive separate hearing notices?

Not merely because a devise or bequest goes to their trust. Section 25 says
notice to the trustee is enough unless a beneficiary is independently entitled
to notice as an heir or as a legatee or devisee of property outside the trust.

Does a court-appointed attorney's pre-probate contest always bar the represented person later?

No. Section 29 preserves a represented party's own post-probate contest if it
is commenced within three months after admission of the will.
