Oklahoma Will Contest Guide

Oklahoma gives two chances to challenge a will, and they run on different clocks. Any interested person may appear and contest the will at the probate hearing under 58 O.S. § 29. Once the district court admits the will, 58 O.S. § 61 leaves three months to file a sworn petition to revoke that probate.

Three months is short. It is shorter than the deadline most families expect, because Oklahoma is not a Uniform Probate Code state and does not carry the three-year window that UPC states use. Miss it and 58 O.S. § 67 makes the probate conclusive, with one narrow saving clause for infants and persons of unsound mind.

Every rule below was read in the Oklahoma Legislature's official compilation of Title 58, Probate Procedure, and Title 84, Wills and Succession, current through the 2025 session. This page explains how the mechanism works. It says nothing about whether a challenge fits your family's facts, and a licensed Oklahoma attorney is the person who answers that. If the estate has not opened yet, the Oklahoma probate guide walks through the case a contest interrupts.

The Two Windows to Contest an Oklahoma Will

The two windows do different work, and the second one is not a second bite at the first. A § 29 contest argues about a will nobody has yet accepted. A § 61 petition asks the court to undo something it already did, and the statute conditions it on evidence discovered since the probate.

One bridge runs between them. Under 58 O.S. § 29, a contest made by an attorney the court appointed does not bar a contest after probate by the party that attorney represented, so long as the later contest starts within three months from the date of admission. 58 O.S. § 710 is where those appointments come from: at or before the hearing, the court may appoint a competent attorney to represent devisees, legatees, heirs, or creditors who are minors with no general guardian in the county, who are nonresidents, or who are otherwise unrepresented.

One kind of will gets double the window. Oklahoma still recognizes a spoken, or nuncupative, will under 84 O.S. § 46, and 58 O.S. § 93 says contests of the probate of nuncupative wills run the same way as contests of written wills, except that double the period allowed for a petition to revoke the probate of a written will is allowed to petition for revocation of the nuncupative one. Six months instead of three, on a will that reached the court under the tight proof rules of 58 O.S. §§ 91 and 92.

Contesting Before the Will Is Admitted

When someone files a petition for probate, 58 O.S. § 25 has the court set a hearing not less than 10 nor more than 30 days out, with notice mailed to the heirs, legatees and devisees at least 10 days before that date. Under 58 O.S. § 28, the appearance in court of interested parties is itself a waiver of notice.

A contest at that stage follows 58 O.S. § 41 and it is a pleading exercise, not a speech at the podium. The contestant files written grounds of opposition to the probate and serves a copy on the petitioner and on other residents of the county interested in the estate. Any one or more of them may demur on any ground of demurrer allowed by law in civil actions. If the demurrer is sustained, the court must allow the contestant a reasonable time, not exceeding 10 days, to amend the written opposition. If it is overruled, the petitioner and other interested parties may answer jointly or separately.

The statute then names the issues of fact the court decides:

1. The competency of the decedent to make a last will and testament.
2. The freedom of the decedent at the time of the execution of the will from duress, menace, fraud, or undue influence.
3. The due execution and attestation of the will by the decedent or subscribing witnesses.
4. Any other questions substantially affecting the validity of the will.

On the trial the contestant is plaintiff and the petitioner is defendant. Under 58 O.S. § 42 the district court must set out its findings of fact and conclusions of law in writing and render judgment either admitting or refusing to admit the will, and the judgment and the will are recorded where the will is admitted.

An objection also changes the proof the proponent has to bring. With no contest, 58 O.S. § 30 lets the court admit a will on the testimony or affidavit of a single subscribing witness, and that shortcut does not apply to self-proved wills because they need no witness at all. Once someone contests, 58 O.S. § 43 requires all the subscribing witnesses who are present in the county and of sound mind to be produced and examined, and the death, absence or insanity of any of them must be shown to the court's satisfaction. Testimony taken at the probate hearing is preserved under 58 O.S. § 44 and is admissible in later proceedings about the will's validity.

The Three-Month Petition After Probate

58 O.S. § 61 is the section most people mean when they ask how to contest an Oklahoma will. Within three months from the date the will was admitted to probate, any person interested may contest the will or its validity by filing, in the court where the will was proved, a sworn written petition setting out the material facts of evidence discovered since the probate. The petition must show one of four things:

• A later will. A will of a later date than the one proved, revoking or changing it, has been discovered and is offered.
• A missing jurisdictional fact. Some jurisdictional fact was wanting in the probate.
• A defect in the testator's mind or will. The testator was not competent, or not free from duress, menace, fraud, or undue influence, when the will allowed was made.
• A defect in the signing. The will was not duly executed and attested.

Read the lead-in as carefully as the list. The petition is framed around evidence discovered since the probate, so a § 61 filing is built on what came to light after the court acted rather than on an argument that was available and skipped at the hearing.

Filing starts a show-cause process. Under 58 O.S. § 62 the court issues a citation to the executors or the administrators with the will annexed, to all the legatees and devisees named in the will, and to the heirs residing in the state so far as the petitioner knows them, or to their guardians if any are minors or adjudicated incompetents, or to their personal representatives if any have died. Those people are called in to show cause why the probate should not be revoked, and a copy of the citation goes by mail to known nonresidents at least 10 days before the hearing. If the petition offers a competing will, 58 O.S. § 63 makes that part of the filing carry everything an original petition for probate would carry, with notice given the same way, except to the people already served with the citation.

58 O.S. § 64 then has the court try the issues the same way it would try an original contest. If the court decides the will is invalid for any reason alleged, or is not proved to be the last will of the testator, the probate must be annulled and revoked. If the court decides a new will is valid, it may admit that one to probate.

Who Counts as an Interested Person

Both sections open the door to a "person interested" rather than to a fixed list. 58 O.S. § 29 adds that devisees, legatees or heirs of an estate may contest through their guardians, or through attorneys they appoint themselves, or through attorneys the court appoints for that purpose. The people who usually hold a stake in setting a will aside are:

• Heirs at law, meaning the relatives who would take under Oklahoma intestate succession if no valid will governs the estate.
• Devisees and legatees under an earlier will, whose share shrank when the challenged document appeared.
• Devisees and legatees named in the challenged will, when an earlier document treated them better.
• A person offering a later will under 58 O.S. § 61(1), who is asking the court to swap one document for another rather than to send the estate into intestacy.

The Grounds Oklahoma Names

Capacity, and the Guardianship Trap

84 O.S. § 41(A) sets the standard for making a will at all: every person over the age of 18 years of sound mind may dispose of the estate, real and personal, by last will.

Subsection (B) carries a rule that catches Oklahoma families off guard. A guardianship or conservatorship does not stop a person from making a will, but a person subject to one must subscribe and acknowledge that will in the presence of a district court judge. The judge attests to the execution and has neither the duty nor the authority to approve or disapprove the contents. Signing before a judge does not save a will that would be invalid for another reason. Read the subsection the other direction too: a will signed by a person subject to a guardianship, without that judicial attestation, has not followed the procedure the statute sets out.

Duress, Menace, Fraud, and Undue Influence

84 O.S. § 43 is one sentence and it does two things. A will, or part of a will, procured to be made by duress, menace, fraud or undue influence may be denied probate. And a revocation procured by the same means may be declared void.

Both halves are useful. The first means a challenge can aim at a single provision rather than at the whole document. The second means the argument runs against a destroyed or replaced will as well as against a signed one, so a family arguing that someone pressured a parent into tearing up an older will is arguing under the same section.

What Title 84 does not do is define undue influence, menace or duress. The definitions and the proof standards come from Oklahoma case law, which is the point in the analysis where an Oklahoma probate litigator earns the fee.

Three features of the statutes set the bar that a challenge has to clear, and they are worth reading together before a contest is treated as a routine step. The contestant is the plaintiff and carries the case (58 O.S. § 41). There is no jury, so a judge decides the facts and issues written findings (§§ 41 and 709). And 58 O.S. § 66 puts the fees and expenses on the contesting party when the will in probate is confirmed. Family disagreement about how an estate was divided is not by itself one of the grounds the sections list, and whether a given set of facts reaches a statutory ground is a question for a licensed Oklahoma attorney rather than for a page.

A Signing That Missed a Step

An execution challenge argues the document never satisfied 84 O.S. § 55. That section requires the will to be subscribed at the end by the testator, or by another person in the testator's presence and by the testator's direction; the subscription to be made in the presence of the attesting witnesses or acknowledged to them; the testator to declare to those witnesses that the instrument is his will; and two attesting witnesses to sign at the end at the testator's request and in the testator's presence. Oklahoma will requirements walks through every route a will here can take to validity, including the handwritten route at 84 O.S. § 54, which needs no witnesses at all if the document is entirely written, dated and signed by the testator's hand.

Two rules blunt this ground more than families expect. 84 O.S. § 56 tells a witness to write a place of residence alongside the signature and then says a violation of that section does not affect the validity of the will. And 84 O.S. § 143 voids a beneficial gift to a subscribing witness unless two other competent subscribing witnesses signed the same will, which strikes the gift rather than the document. A witness who loses a gift that way may still take up to its value under 84 O.S. § 144 if that witness would have inherited had the will failed.

Revocation and a Competing Document

84 O.S. § 101 allows only two ways to revoke a written will. One is another will or a writing of the testator declaring the revocation, executed with the same formalities a will would need. The other is burning, tearing, canceling, obliterating or destroying the will with intent and for the purpose of revoking it, done by the testator or by someone in the testator's presence and by the testator's direction.

Four companion sections decide most competing-document fights:

• A destruction someone else carried out needs corroboration. 84 O.S. § 102 requires the testator's direction and the fact of the injury or destruction to be proved by two witnesses.
• A partial obliteration counts under 84 O.S. § 103 if the material part is so obliterated as to show an intention to revoke, but an obliteration made to substitute a new disposition fails unless that new disposition is legally effected.
• A later will does not automatically wipe out an earlier one. 84 O.S. § 105 revokes the prior will only where the later one expressly revokes it or contains provisions wholly inconsistent with it, and otherwise the prior will remains effectual so far as it is consistent.
• Destroying a later will does not revive the earlier one under 84 O.S. § 106 unless the terms of the revocation show that intent, or the testator republishes the prior will afterward.

Divorce works automatically. 84 O.S. § 114 revokes all provisions in favor of a spouse the testator later divorced, treats that former spouse as having predeceased the testator for every purpose under the will, and gives an annulment the same effect. The section does not apply if the decree is vacated, if the testator remarries the former spouse, or if the testator executes a new will or codicil that is not revoked or held invalid. It reaches the will of any decedent dying on or after November 1, 1987.

If the document itself has gone missing, the path is 58 O.S. §§ 81 through 83 rather than a contest. 58 O.S. § 82 will not let a lost or destroyed will be proved unless it existed at the testator's death or was fraudulently destroyed during the testator's lifetime, and unless its provisions are clearly and distinctly proved by at least two credible witnesses.

What a Self-Proving Affidavit Does Not Do Here

In many states a self-proving affidavit closes the execution question for good. Oklahoma writes the opposite rule into the statute itself.

84 O.S. § 55(7) says a self-proved testamentary instrument is admitted to probate without the testimony of any subscribing witness, unless contested, and that otherwise it is treated no differently than a will or codicil that is not self-proved. The subsection closes by saying such an instrument may be contested as a will not self-proved. Pair that with 58 O.S. § 43, which calls every available subscribing witness to the stand once a contest is on foot, and the affidavit turns out to buy an uncontested shortcut rather than a shield.

No Jury, and No Statute on No-Contest Clauses

Two structural facts shape how an Oklahoma contest feels.

There is no jury. 58 O.S. § 41 says the issues raised in a will contest must be tried and determined by the court, and 58 O.S. § 709 generalizes it: all issues of fact joined in a probate proceeding must be tried by the court, the party affirming is plaintiff and the one denying or avoiding is defendant, and after the hearing the court gives its findings of fact and conclusions of law in writing. Where the pleadings do not frame the issues well enough, § 709 has the court settle and frame them on notice to the other side.

And the code is silent on no-contest clauses. Reading Title 58 and Title 84 end to end in the official compilation turns up no section on penalty clauses, no-contest clauses or in terrorem clauses, and no probable-cause escape hatch of the sort other states legislate. Oklahoma case law governs the question instead, which is a real limit on what a page like this one can tell you. If the will you are looking at contains a forfeiture clause, that clause is a question for an Oklahoma attorney before anything gets filed.

Where the Case Runs and What It Costs

Oklahoma has no separate probate court. 58 O.S. § 1(A)(1) gives the district court probate jurisdiction to open and receive proof of wills, to admit them to proof, and to revoke the probate of them. All 77 counties are served by their district court, and Oklahoma probate courts by county lists the courthouse and court clerk for each.

Venue comes from 58 O.S. § 5. For a decedent who died a resident of Oklahoma, it is the county of residence at death, regardless of where the death occurred. For a nonresident, it runs first to the county where the decedent died leaving an estate there, then to any county holding part of the estate, then to the county of death. 58 O.S. § 7 makes the first county's jurisdiction coextensive with the state and excludes every other county, which is why a contest does not move to where the heirs live.

Filing fees are set statewide by statute. 28 O.S. § 152(A)(6) charges $43.00 for any proceeding to revoke the probate of a will, against $135.00 for the probate case itself under § 152(A)(3). Several assessments ride along: $25.00 to the Oklahoma Court Information System under § 152(C), $10.00 to Oklahoma court-appointed special advocates under § 152(D), $2.00 for judicial complaints and courtroom interpreters under § 152(E), and, until November 1, 2027, another $10.00 for records management under § 152(G). 12 O.S. § 1809(A) taxes a further $7.00 for the alternative dispute resolution system in all civil cases.

Two of the add-ons do not attach to a revocation proceeding. The $6.00 law library assessment in § 152(B) and the county-option courthouse security charge of up to $10.00 in § 152(F) are both keyed to specific paragraphs of subsection A, and paragraph 6 is not among them. Adding the charges that do apply comes to $97.00 as of this writing, but that arithmetic is ours rather than a figure any statute prints, so confirm the current total with the court clerk. § 152(H) sets out the in forma pauperis route for a litigant who cannot pay.

Then there is the loser-pays rule, which is the number that actually matters. 58 O.S. § 66 makes the contestant pay the fees and expenses if the will in probate is confirmed. If the probate is annulled and revoked, costs fall on the party who resisted the revocation, or come out of the decedent's property, as the court directs.

What Happens If the Contest Succeeds

When the court annuls and revokes a probate, 58 O.S. § 65 ends the powers of the executor or the administrator with the will annexed. That person is not liable for acts done in good faith before the revocation, which protects a personal representative who paid a funeral bill or filed a tax return while the case was pending. The remaining duties, and who picks them up next, are covered in Oklahoma executor duties.

Where the estate goes depends on what is left standing. If the court admits a later will under 58 O.S. § 64, that document controls. If no valid will remains, the estate passes under Oklahoma's descent and distribution statute, described in Oklahoma intestate succession. Either way the calendar stretches, and the Oklahoma probate timeline shows what the ordinary schedule looks like before a dispute lands on it. Creditor deadlines keep running through all of it, as Oklahoma creditor claims explains.

Problems That Look Like Contests But Are Not

Several common complaints have their own remedy under a different section, so a contest is not the mechanism that addresses them, and the three-month § 61 window keeps running while one is pending.

• A child left out of the will. 84 O.S. § 132 gives a child, or the issue of a deceased child, whom the testator omitted to provide for the same share as if the testator had died intestate, unless it appears the omission was intentional. 84 O.S. § 131 does the same for a child born after the will was made and left unprovided for. 84 O.S. § 133 sets where that share is taken from.
• A surviving spouse cut down. 84 O.S. § 44(B) bars a spouse from devising away from the other so much of the estate that the survivor receives less than an undivided one-half interest in the property acquired by the joint industry of the husband and wife during coverture, and gives the survivor a right of election to take that half in lieu of everything the will leaves. The election has to be made affirmatively in writing, filed in the district court administering the estate on or before the final date for hearing the petition for final distribution, and in a writing separate from every other pleading. Failure to substantially comply voids the attempt, though the spouse may try again inside the same period.
• A gift to one of the witnesses. 84 O.S. § 143 voids the gift, not the will.
• A complaint about how the estate is being run. Objecting to the personal representative, to an accounting, or to a sale is a different motion inside the same case, and none of it turns on whether the will is valid.

Appeals and Reopening

58 O.S. § 721 lists what can be appealed from a district court in a probate cause, and three of its paragraphs cover this ground: an order granting, refusing or revoking letters testamentary; an order admitting or refusing to admit a will to probate; and an order against or in favor of the validity of a will or revoking the probate of one. Paragraph 10 sweeps in any other order in a probate cause affecting a substantial right. Under 58 O.S. § 722 a party may not appeal from an order made on that party's own default.

58 O.S. § 724 says a probate appeal is taken the way appeals in other cases are taken, which routes it to 12 O.S. § 990A(A): a petition in error filed with the Clerk of the Supreme Court of Oklahoma within 30 days from the date the judgment or appealable order is filed with the trial court clerk.

An appeal does not freeze the estate. 58 O.S. § 731 lets letters issue during an appeal from an order admitting a will to probate where the judge finds that preserving the estate requires it, though those letters confer no power to sell real property under the will, to pay legacies, or to distribute to the next of kin until the appeal is finally determined.

There is also a narrower door. 58 O.S. § 723 lets a person interested in the estate who was not a party to the proceeding, but who was entitled by law to be heard, move to reopen the judgment within 30 days of the decree or order, supported by an affidavit filed with the motion. The same right belongs to someone who acquired a qualifying interest after the order was made.

Frequently Asked Questions

How long do you have to contest a will in Oklahoma?

Three months after the will is admitted, and there is an earlier window too. 58 O.S. § 29 lets any interested person appear and contest the will at the probate hearing itself. Once the court admits the will, 58 O.S. § 61 gives any person interested three months from the date of admission to file a sworn petition to revoke that probate. 58 O.S. § 67 then makes the probate conclusive if nobody contests within those three months, saving to infants and persons of unsound mind a period of one year after their respective disabilities are removed.

What are the grounds to contest a will in Oklahoma?

58 O.S. § 41 lists the issues tried in a pre-probate contest: the competency of the decedent to make a will, the freedom of the decedent at the time of execution from duress, menace, fraud, or undue influence, the due execution and attestation of the will, and any other question substantially affecting the validity of the will. 58 O.S. § 61 lists four causes after probate: a later will has been discovered and is offered, a jurisdictional fact was wanting, the testator was not competent or free from duress, menace, fraud, or undue influence, or the will was not duly executed and attested. 84 O.S. § 43 supplies the substantive rule that a will or part of a will procured by duress, menace, fraud or undue influence may be denied probate.

What court hears an Oklahoma will contest?

The district court that has the probate. Oklahoma has no separate probate court. 58 O.S. § 1(A)(1) gives the district court power to receive proof of wills, admit them to proof, and revoke the probate of them. Venue under 58 O.S. § 5 is the county where the decedent lived at death, regardless of where the death happened, and for a nonresident it runs first to the county where the decedent died leaving an estate. 58 O.S. § 7 then makes that county's jurisdiction coextensive with the state and excludes every other county.

Can you get a jury trial in an Oklahoma will contest?

No. 58 O.S. § 41 says the issues raised in a will contest must be tried and determined by the court, and 58 O.S. § 709 says all issues of fact joined in a probate proceeding must be tried by the court. The judge then gives written findings of fact and conclusions of law. On the trial the contestant is plaintiff and the person offering the will is defendant.

Do no-contest clauses work in Oklahoma?

The statutes do not answer this. A full-text reading of Title 58, Probate Procedure, and Title 84, Wills and Succession, in the Oklahoma Legislature's official compilation turns up no section on penalty clauses, no-contest clauses, or in terrorem clauses, and no probable-cause safe harbor of the kind other states write into their codes. That silence means Oklahoma case law governs the question, so ask a licensed Oklahoma attorney what a specific clause does before filing anything.

Does a self-proving affidavit stop an Oklahoma will contest?

No, and Oklahoma says so on the face of the statute. 84 O.S. § 55(7) admits a self-proved will without the testimony of any subscribing witness unless contested, and then adds that it is treated no differently than a will that is not self-proved and may be contested as a will not self-proved. 58 O.S. § 43 completes the picture: once a will is contested, all subscribing witnesses who are present in the county and of sound mind must be produced and examined.

Who pays the costs of an Oklahoma will contest?

58 O.S. § 66 splits it by outcome. If the will in probate is confirmed, the fees and expenses are paid by the party who contested the validity or the probate of the will. If the probate is annulled and revoked, the costs are paid by the party who resisted the revocation, or out of the property of the decedent, as the court directs.
