✓ Verified September 2026

To contest a will in Hawaii, you file in the probate court within a fixed window and prove one of a short list of legal grounds. This guide gives the Hawaii 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 Hawaii law, verified as of September 2026.

Contest a Will in Hawaii: At a Glance

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

Deadline to contest For a will admitted by INFORMAL probate, a contest must be commenced by the EARLIEST of: 90 days after receiving notice of the informal proceeding, 12 months from the date the will was informally admitted to probate, or 30 days from entry of a formal order approving the accounts and settlement of the estate by an informally appointed personal representative — HRS 560:3-108(a)(3). For a will admitted in a FORMAL testacy proceeding, the order is final as to all persons, and a petition to modify or vacate it must generally be filed within 12 months after entry of the order — HRS 560:3-412(3). Outer limit: no informal probate or formal testacy proceeding may be commenced more than 5 years after the decedent’s death — HRS 560:3-108(a). Where an informal proceeding was closed informally and the court finds notice of the informal probate was NOT given, the court has discretion to allow a late contest so long as not more than 5 years have elapsed since death — HRS 560:3-108.
What starts the clock Three separate triggers run concurrently and the shortest controls: (1) the date the interested person RECEIVES NOTICE of the informal probate proceeding (90 days), (2) the date the will was ADMITTED TO PROBATE informally (12 months), and (3) ENTRY OF THE FORMAL ORDER approving the accounts and settlement of the estate (30 days) — HRS 560:3-108(a)(3). For formal probate the trigger is ENTRY OF THE FORMAL TESTACY ORDER (12 months) — HRS 560:3-412(3). The 5-year outer bar runs from DATE OF DEATH — HRS 560:3-108(a).
Who can contest Only an “interested person” may petition — HRS 560:3-401 (formal testacy proceedings may be commenced by an interested person, including a petition to set aside an informal probate or to prevent informal probate). “Interested person” is defined at HRS 560:1-201 to include heirs, devisees, children, spouses, reciprocal beneficiaries, creditors, beneficiaries, and any others having a property right in or claim against the estate, plus persons having priority for appointment as personal representative and fiduciaries representing interested persons; the meaning is determined according to the particular purposes of and matter involved in any proceeding. Hawaii appellate decisions construing HRS 560:1-201 have held that a person with no property right in or claim against the estate, no familial relationship, and no appointment priority is NOT an interested person and lacks standing (e.g., denial of media intervention as “interested persons”). Beneficiaries under a prior or later will and intestate heirs who would take if the will fails therefore have standing; a stranger to the estate does not.
No-contest clause YES with a PROBABLE-CAUSE exception. HRS 560:3-905 (“Penalty clause for contest”): a provision in a will purporting to penalize any interested person for contesting the will or instituting other proceedings relating to the estate is UNENFORCEABLE IF PROBABLE CAUSE EXISTS for instituting the proceedings. The parallel trust/nonprobate-transfer provision is HRS 560:2-517. So a no-contest clause is given effect against a contestant who sues without probable cause, but is not enforced against a contestant who had probable cause.
What the filing is called A “Petition for Formal Testacy Proceeding” — specifically a petition to set aside the informal probate of a will, or a petition to prevent informal probate of a will that is the subject of a pending application, or a petition for formal probate of a different will together with an objection to the offered will — filed under HRS 560:3-401 and HRS 560:3-402 in the probate division of the circuit court. Under the Hawai’i Probate Rules, a party may also file an OBJECTION to a pending petition; once a matter becomes contested the court may assign it to the civil trials calendar under Hawai’i Probate Rule 20, after which the Hawai’i Rules of Civil Procedure and the Rules of the Circuit Courts apply to the referred petition.
Court The Circuit Court of the State of Hawai’i, Probate Division. The circuit courts have exclusive original jurisdiction over probate matters (HRS 560:1-302 and HRS 603-21.6), sitting in Hawaii’s four judicial circuits: First Circuit (Oahu, Honolulu), Second Circuit (Maui, Molokai, Lanai), Third Circuit (Hawai’i Island), and Fifth Circuit (Kauai and Niihau). Procedure is governed by the Hawai’i Probate Rules. There is no separate “surrogate’s court” in Hawaii.
Jury trial LIMITED — not a general right. HRS 560:1-306(a): “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 constitutional right to trial by jury.” Because will contests are historically equitable, the practical effect is that a jury is available only where a constitutional jury right independently exists for the controverted fact question. HRS 560:1-306(b): if there is no such right, or the right is waived, the court in its discretion may call a jury whose verdict is ADVISORY ONLY. Hawai’i Probate Rule 20 confirms that assignment of a contested matter to the civil trials calendar does NOT itself create a right to jury trial where none exists in the underlying proceeding. Practical answer for most Hawaii will contests: NO — tried to the probate judge.
Typical cost UNVERIFIED — no Hawaii Judiciary, Hawaii State Bar Association, or Hawaii statutory source publishes a typical dollar range for a contested will case. Filing fees for probate petitions are set by the Hawai’i Judiciary fee schedule; attorney fees are set by private agreement and vary widely. Check with the circuit court clerk or a licensed Hawaii attorney for current figures.

The Deadline to Contest a Will in Hawaii

⚠ Deadline to contest a will in Hawaii: For a will admitted by INFORMAL probate, a contest must be commenced by the EARLIEST of: 90 days after receiving notice of the informal proceeding, 12 months from the date the will was informally admitted to probate, or 30 days from entry of a formal order approving the accounts and settlement of the estate by an informally appointed personal representative — HRS 560:3-108(a)(3).

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 Hawaii

Under HRS 560:3-407 the contestant may establish: lack of testamentary intent or testamentary capacity, undue influence, fraud, duress, mistake, and revocation. Improper execution / failure to meet the signing and witnessing formalities of HRS 560:2-502 (or the harmless-error / clear-and-convincing route in HRS 560:2-503) is also a ground, because proponents carry the burden of due execution under HRS 560:3-407.

Forgery is litigated in Hawaii as a failure of due execution and as fraud. On undue influence Hawaii courts apply the “SODR” factors (susceptibility, opportunity, disposition, result) recognized in In re Will of Notley and In re Estate of Afong, and applied in In re Estate of Herbert, 90 Hawai’i 443 (1999).

Who has to prove what: Split under HRS 560:3-407. PROPONENTS of a will have the burden of establishing prima facie proof of DUE EXECUTION in all cases, and, if they are also petitioners, proof of death, venue, and heirship. CONTESTANTS then have the burden of establishing lack of testamentary intent or capacity, undue influence, fraud, duress, mistake, or revocation.

Parties have the ultimate burden of persuasion as to matters they have the burden to establish. The civil standard — preponderance of the evidence — applies to these elements (note HRS 560:2-503 separately requires CLEAR AND CONVINCING evidence to excuse a formality defect under the harmless-error rule).

PRESUMPTION: where a will or trust proponent stood in a fiduciary or confidential relationship with the testator, Hawaii case law raises a presumption of undue influence and shifts the burden to the proponent to show the absence of undue influence — see In re Estate of Herbert, 90 Hawai’i 443 (1999). Hawaii also applies the “SODR” factors from In re Will of Notley and In re Estate of Afong.

Who Can Contest a Will in Hawaii

Only an “interested person” may petition — HRS 560:3-401 (formal testacy proceedings may be commenced by an interested person, including a petition to set aside an informal probate or to prevent informal probate).

“Interested person” is defined at HRS 560:1-201 to include heirs, devisees, children, spouses, reciprocal beneficiaries, creditors, beneficiaries, and any others having a property right in or claim against the estate, plus persons having priority for appointment as personal representative and fiduciaries representing interested persons; the meaning is determined according to the particular purposes of and matter involved in any proceeding.

Hawaii appellate decisions construing HRS 560:1-201 have held that a person with no property right in or claim against the estate, no familial relationship, and no appointment priority is NOT an interested person and lacks standing (e.g., denial of media intervention as “interested persons”).

Beneficiaries under a prior or later will and intestate heirs who would take if the will fails therefore have standing; a stranger to the estate does not. Being unhappy with the will is not standing; losing something because of it is. Check the earlier will and the intestate rules for Hawaii before filing, because they decide whether you are an interested person.

No-Contest Clauses in Hawaii

YES with a PROBABLE-CAUSE exception. HRS 560:3-905 (“Penalty clause for contest”): a provision in a will purporting to penalize any interested person for contesting the will or instituting other proceedings relating to the estate is UNENFORCEABLE IF PROBABLE CAUSE EXISTS for instituting the proceedings. The parallel trust/nonprobate-transfer provision is HRS 560:2-517.

So a no-contest clause is given effect against a contestant who sues without probable cause, but is not enforced against a contestant who had probable cause.

The Steps to Contest a Will in Hawaii

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” — specifically a petition to set aside the informal probate of a will, or a petition to prevent informal probate of a will that is the subject of a pending application,

or a petition for formal probate of a different will together with an objection to the offered will — filed under HRS 560:3-401 and HRS 560:3-402 in the probate division of the circuit court.

Under the Hawai’i Probate Rules, a party may also file an OBJECTION to a pending petition; once a matter becomes contested the court may assign it to the civil trials calendar under Hawai’i Probate Rule 20, after which the Hawai’i Rules of Civil Procedure and the Rules of the Circuit Courts apply to the referred petition..

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

Settling Instead of Fighting

YES. Two express statutory routes. (1) HRS 560:3-912 — competent successors may 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 intestacy; the personal representative must abide by the agreement, subject to creditors, taxes, costs of administration, and the interests of successors who are not parties.

(2) HRS 560:3-1101 and HRS 560:3-1102 — a COMPROMISE of any controversy as to admission of an instrument to formal probate, the construction, validity, or effect of a governing instrument, the rights or interests of any successor, or the administration of the estate, IF APPROVED in a formal proceeding in the court for that purpose, is binding on all parties including persons unborn, unascertained, or who could not be located,

and binds even trusts and inalienable interests; it does not impair the rights of creditors or taxing authorities who are not parties.

HRS 560:3-1102 sets the procedure (written agreement executed by all competent persons and parents acting for minor children, plus petition, notice, and court findings). Mediation is also routinely used for contested probate matters referred to the civil trials calendar under Hawai’i Probate Rule 20.

Other Hawaii rules: (1) NO ante-mortem / pre-death will validation in Hawaii — a will cannot be judicially validated during the testator’s lifetime; contests arise only after death. (2) Hawaii DEPARTS from the standard Uniform Probate Code outer limit: HRS 560:3-108 uses FIVE YEARS after death, not the UPC’s three years.

(3) Rare late-contest safety valve — if an informal proceeding was closed informally and the court determines notice of the informal probate was not provided, the court in its DISCRETION may allow a contest after the limitations period has expired, provided not more than 5 years have elapsed since death (HRS 560:3-108).

(4) SELF-PROVED WILLS — HRS 560:2-504 permits a will to be simultaneously executed, attested, and made self-proved by the testator’s acknowledgment and witnesses’ affidavits before a notary; HRS 560:3-406 provides that if the will is self-proved, compliance with signature requirements is CONCLUSIVELY PRESUMED and other execution requirements are presumed, subject only to contest on the grounds of fraud or forgery affecting the acknowledgment or affidavit.

This makes a Hawaii self-proved will substantially harder to attack on execution grounds. (5) HARMLESS ERROR — HRS 560:2-503 lets a defectively executed document be treated as a valid will if the proponent establishes by CLEAR AND CONVINCING evidence that the decedent intended it as a will; Hawaii also recognizes holographic wills under HRS 560:2-502(b).

(6) HRS 560:3-108 limits do NOT apply to proceedings to construe probated wills or to determine heirs of an intestate. (7) Hawai’i Probate Rule 20 governs referral of contested matters to the civil trials calendar and expressly does not create a jury-trial right. (8) “Reciprocal beneficiaries” are expressly included in the HRS 560:1-201 definition of interested person — a Hawaii-specific status category.

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: Hawaii 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 Hawaii, 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 Hawaii

A will contest is a lawsuit about the document, not about fairness. When you contest a will in Hawaii, 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 Hawaii 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 Hawaii, 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 Hawaii

  • The deadline is everything: the window to contest a will in Hawaii 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 Hawaii on capacity, undue influence, fraud, duress, or bad execution, never on unfairness alone.
  • Standing first: only an interested person can contest a will in Hawaii; check whether you inherit under the prior will or the intestate rules.
  • Read the no-contest clause: whether the state enforces it decides how much risk it takes to contest a will in Hawaii.

  • Notice defects are a lifeline: if you never got the required notice, you may still contest a will in Hawaii after the ordinary deadline.
