How to Contest a Will in Utah — Deadline, Grounds, and Who Can File (2026)

✓ Verified September 2026

To contest a will in Utah, you file in the probate court within a fixed window and prove one of a short list of legal grounds. This guide gives the Utah answer in plain English, and it starts with the deadline, because that is the fact that ends more cases than any other. All facts are from Utah law, verified as of September 2026.

Contest a Will in Utah: At a Glance

Here are the Utah facts that decide whether you can contest a will in Utah:

Deadline to contest Two different clocks apply. (1) Informally probated will — a contest must be commenced within the LATER of 12 months from the date of the informal probate OR 3 years from the decedent’s death (Utah Code § 75-3-107(1)(c)). (2) Outer limit — no informal probate or formal testacy proceeding may be commenced more than 3 years after the decedent’s death, after which the presumption of intestacy becomes final (Utah Code § 75-3-107(1)). (3) Formally probated will — objections must be raised in the pleadings before/at the formal testacy hearing (Utah Code § 75-3-404); once entered, the formal testacy order is final and binding on all persons given notice and may be reopened only in the narrow circumstances listed in Utah Code § 75-3-412 (later-discovered will whose proponents were unaware of it or received no notice except by publication; omitted heirs unaware of the relationship, the death, or given no notice except by publication).
What starts the clock For an informally probated will, the clock runs from the date the will was admitted to informal probate (12 months) and, alternatively, from the date of death (3 years) — the contestant gets whichever date is later (§ 75-3-107(1)(c)). The absolute 3-year bar runs from the date of death (§ 75-3-107(1)). In a formal testacy proceeding, the operative trigger is the notice of hearing given under §§ 75-3-403 and 75-1-401 — notice must be mailed at least 10 days before the hearing, posted for 10 consecutive days in at least 3 public places in the county, or published at least 10 days before the hearing.
Who can contest Any “interested person” may commence a formal testacy proceeding or petition to set aside an informal probate (Utah Code § 75-3-401). “Interested person” is defined at Utah Code § 75-1-201 and includes heirs, devisees, children, spouses, creditors, beneficiaries, and any others having a property right in or claim against the estate of the decedent, plus persons having priority for appointment as personal representative and fiduciaries representing interested persons. The statute expressly provides that the meaning as applied to particular persons may vary from time to time and is determined according to the particular purposes of, and matter involved in, any proceeding — so standing is assessed proceeding-by-proceeding. Beneficiaries under a prior will and creditors are within the definition.
No-contest clause YES with a probable-cause exception. Utah Code § 75-2-515 (“Penalty clause for contest”) provides that a provision in a will purporting to penalize an interested person for contesting the will or instituting other proceedings relating to the estate is unenforceable if probable cause exists for instituting proceedings. A parallel provision governs distribution under Utah Code § 75-3-905. Practical effect: a no-contest clause in a Utah will is enforceable only against a contest brought without probable cause.
What the filing is called A “petition for formal testacy proceeding” (also called a petition to set aside an informal probate of a will, or a petition to prevent informal probate of a will that is the subject of a pending application) filed under Utah Code § 75-3-401. A party already before the court in a formal proceeding who opposes probate states the objections in a pleading — “written objections to probate” — under Utah Code § 75-3-404. Filed in the district court of the county where the decedent was domiciled at death, or the district court of the county where the decedent owned property.
Court The Utah District Court. Utah has no separate probate or surrogate court; the district courts exercise original jurisdiction over all civil matters, including probate and will contests (Utah Code § 78A-5-102; Utah Code § 75-1-302). Some judicial districts route probate matters through court commissioners for pretrial handling.
Jury trial YES. Utah Code § 75-1-306(1): “If duly demanded, a party is entitled to trial by jury in a formal testacy proceeding and any proceeding in which any controverted question of fact arises as to which any party has a statutory or constitutional right to trial by jury.” The demand must be duly made. If there is no such right, or it is waived, § 75-1-306(2) allows the court in its discretion to call a jury whose verdict is advisory only.
Typical cost UNVERIFIED — no Utah court, legislature, or state bar source publishes a cost range for contested will cases. Utah does publish court filing fees and offers fee waivers via a poverty affidavit for those who cannot afford court costs; you may be able to request a waiver. Check with the Utah district court clerk or a licensed Utah attorney for current fees and likely litigation costs.

The Deadline to Contest a Will in Utah

⚠ Deadline to contest a will in Utah: Two different clocks apply. (1) Informally probated will — a contest must be commenced within the LATER of 12 months from the date of the informal probate OR 3 years from the decedent’s death (Utah Code § 75-3-107(1)(c)). (2) Outer limit — no informal probate or formal testacy proceeding may be commenced more than 3 years after the decedent’s death, after which the presumption of intestacy becomes final (Utah Code § 75-3-107(1)). (3) Formally probated will — objections must be raised in the pleadings before/at the formal testacy hearing (Utah Code § 75-3-404); once entered, the formal testacy order is final and binding on all persons given notice and may be reopened only in the narrow circumstances listed in Utah Code § 75-3-412 (later-discovered will whose proponents were unaware of it or received no notice except by publication; omitted heirs unaware of the relationship, the death, or given no notice except by publication).. The clock starts at For an informally probated will, the clock runs from the date the will was admitted to informal probate (12 months) and, alternatively, from the date of death (3 years) — the contestant gets whichever date is later (§ 75-3-107(1)(c)). The absolute 3-year bar runs from the date of death (§ 75-3-107(1)). In a formal testacy proceeding, the operative trigger is the notice of hearing given under §§ 75-3-403 and 75-1-401 — notice must be mailed at least 10 days before the hearing, posted for 10 consecutive days in at least 3 public places in the county, or published at least 10 days before the hearing.. Missing it usually ends the case regardless of how strong the grounds are.

The window is short in some states and long in others, and it is measured from a specific event rather than from the day you learned about the will. That is why the first thing to find out is the date the will was admitted and whether you received formal notice. If the deadline has not run, everything else on this page is available to you.

If it has, the remaining options are narrow and usually involve proving you never got the notice the law required.

Grounds to Contest a Will in Utah

Utah Code § 75-3-407 identifies the grounds a contestant must prove: lack of testamentary intent, lack of testamentary capacity, undue influence, fraud, duress, mistake, and revocation. Improper execution is also contestable, but as a failure of the proponent’s prima facie case — the proponent of the will always carries the burden of establishing prima facie proof of due execution (§ 75-3-407).

Forgery is addressed separately: a self-proved will’s signature compliance is conclusively presumed unless there is proof of fraud or forgery affecting the acknowledgment or affidavits (§ 75-3-406).

Who has to prove what: Split burdens under Utah Code § 75-3-407. The proponent of a will has the burden of establishing prima facie proof of due execution in all cases, and, if also the petitioner, prima facie proof of death and venue. Petitioners seeking to establish intestacy have the burden of prima facie proof of death, venue, and heirship.

Contestants then carry the burden of establishing lack of testamentary intent or capacity, undue influence, fraud, duress, mistake, or revocation. Except where a presumption is operable, parties have the ultimate burden of persuasion as to matters on which they carry the initial burden; where one or more presumptions are operable, the ultimate burden of persuasion is determined in accordance with the Utah Rules of Evidence.

Presumption: under Utah case law, undue influence is presumed where a confidential relationship exists between the testator and a beneficiary who benefits under the will, shifting the burden to the beneficiary.

Utah appellate decisions have applied a preponderance-of-the-evidence standard to will contest grounds generally, but the specific standard applied to a given ground and presumption should be confirmed with a licensed Utah attorney — UNVERIFIED as to a single statutory standard, because § 75-3-407 sets no numeric standard and defers to the Utah Rules of Evidence.

Who Can Contest a Will in Utah

Any “interested person” may commence a formal testacy proceeding or petition to set aside an informal probate (Utah Code § 75-3-401). “Interested person” is defined at Utah Code § 75-1-201 and includes heirs, devisees, children, spouses, creditors, beneficiaries, and any others having a property right in or claim against the estate of the decedent, plus persons having priority for appointment as personal representative and fiduciaries representing interested persons.

The statute expressly provides that the meaning as applied to particular persons may vary from time to time and is determined according to the particular purposes of, and matter involved in, any proceeding — so standing is assessed proceeding-by-proceeding. Beneficiaries under a prior will and creditors are within the definition. Being unhappy with the will is not standing; losing something because of it is.

Check the earlier will and the intestate rules for Utah before filing, because they decide whether you are an interested person.

No-Contest Clauses in Utah

YES with a probable-cause exception. Utah Code § 75-2-515 (“Penalty clause for contest”) provides that a provision in a will purporting to penalize an interested person for contesting the will or instituting other proceedings relating to the estate is unenforceable if probable cause exists for instituting proceedings. A parallel provision governs distribution under Utah Code § 75-3-905.

Practical effect: a no-contest clause in a Utah will is enforceable only against a contest brought without probable cause.

The Steps to Contest a Will in Utah

Step one is the deadline check above. Step two is evidence: the medical records around the signing date, the names of the witnesses, the drafting lawyer’s file, and the financial records that show who benefited.

Step three is the filing — A “petition for formal testacy proceeding” (also called a petition to set aside an informal probate of a will, or a petition to prevent informal probate of a will that is the subject of a pending application) filed under Utah Code § 75-3-401.

A party already before the court in a formal proceeding who opposes probate states the objections in a pleading — “written objections to probate” — under Utah Code § 75-3-404. Filed in the district court of the county where the decedent was domiciled at death, or the district court of the county where the decedent owned property..

Step four is discovery and, in most cases, a settlement conference; the small minority that reach trial are decided by a jury if requested.

Settling Instead of Fighting

YES.

Utah Code § 75-3-912 (Private agreements among successors to decedent binding on personal representative) allows competent successors to agree among themselves, in a written contract executed by all who are affected, to alter the interests, shares, or amounts to which they are entitled under the will or under the laws of intestacy; the personal representative must abide by the terms, subject to the obligation to administer the estate for creditors,

to pay all taxes and costs of administration, and to protect successors who are not parties.

Such agreements remain subject to the rights of creditors and taxing authorities. The Utah State Courts also provide alternative dispute resolution and mediation for probate cases: https://www.utcourts.gov/en/about/miscellaneous/mediation/adr-prob.html

Other Utah rules: (1) NO ante-mortem / living probate in Utah — pre-death judicial validation of a will is available only in Alaska, Arkansas, Delaware, Nevada, New Hampshire, North Carolina, North Dakota, Ohio, and South Dakota; Utah is not among them.

(2) Self-proved wills: under Utah Code § 75-3-406, if the will is self-proved, compliance with signature requirements for execution is conclusively presumed and other execution requirements are presumed subject to rebuttal, without the testimony of any witness, unless there is proof of fraud or forgery affecting the acknowledgment or affidavits — this is a materially higher bar for an execution-based contest.

Under Utah Code § 75-2-504, a signature affixed to a self-proving affidavit attached to a will counts as a signature affixed to the will if needed to prove due execution. (3) Non-self-proved attested wills: in contested cases, the testimony of at least one attesting witness is required if that witness is within the state, competent, and able to testify; due execution may otherwise be proved by other evidence (§ 75-3-406).

(4) Holographic wills are valid in Utah without witnesses if the signature and material portions of the document are in the testator’s handwriting (Utah Code § 75-2-502) — authenticity of handwriting is a common contest issue. (5) Waiting period: an informal probate may not be filed until 120 hours (5 days) have passed since the death.

(6) Formal testacy orders are final and binding on all persons given notice, subject only to the narrow reopening grounds in § 75-3-412 — a person who receives notice and does not object generally loses the ability to contest later.

The Evidence That Wins or Loses a Will Contest

Capacity cases turn on the weeks around the signing: the medical chart, prescriptions, a dementia diagnosis, and what the drafting lawyer and the witnesses saw that day. A will signed in a lawyer’s office with two disinterested witnesses and a self-proving affidavit is hard to attack; a will signed at a kitchen table with the main beneficiary present is not.

Undue influence cases turn on the relationship — who drove the parent to the appointment, who chose the lawyer, who was in the room, and whether the new will departed sharply from earlier ones and from what the parent said to other people.

Improper execution is the narrowest ground and the cleanest: Utah sets exact witness and signature rules, and a will that misses them fails regardless of what the signer intended. Before you contest a will in Utah, gather the prior wills, the medical releases, and the names of everyone at the signing.

Most of that evidence has to be requested formally once the case is filed, and the deadline does not wait for it.

What to Expect When You Contest a Will in Utah

A will contest is a lawsuit about the document, not about fairness. When you contest a will in Utah, the court asks whether the person who signed it had capacity, signed it freely, and signed it correctly. It does not ask whether the split was reasonable. That is why the strongest cases rest on medical records and witness accounts from the weeks around the signing.

Most families who contest a will in Utah settle. Courts encourage it, many states have family settlement rules that let the heirs agree to a different division, and a settlement avoids the cost and delay of trial. The deadline, the grounds, and the no-contest clause above are the three facts that set your bargaining position before any of that begins.

You don’t have to do this alone

If you are settling a loved one’s estate in Utah, your state’s probate court self-help center and free legal-aid offices can walk you through the process at no cost. For an active probate or a deadline, talk to a licensed probate attorney in your state.

Key Takeaways: Contest a Will in Utah

  • The deadline is everything: the window to contest a will in Utah closes on a fixed schedule, and the court cannot reopen it for a late but valid claim.
  • Grounds are specific: you contest a will in Utah on capacity, undue influence, fraud, duress, or bad execution, never on unfairness alone.
