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

Contest a Will in Minnesota: At a Glance
Here are the Minnesota facts that decide whether you can contest a will in Minnesota:
| Deadline to contest | For a will admitted to INFORMAL probate, a formal testacy proceeding to contest it must be commenced within the LATER of 12 months from the informal probate or 3 years from the decedent’s death — Minn. Stat. 524.3-108(3). For a will admitted in a FORMAL testacy proceeding, objections must be filed in the pleadings before the hearing (Minn. Stat. 524.3-401, 524.3-404); once the formal testacy order is entered it is final, and a petition to vacate must be filed within 12 months after entry of the order and before the earlier of the order approving final distribution or 6 months after a closing statement is filed, and never after the 524.3-108 outer limit — Minn. Stat. 524.3-412(3). The overall outer limit is 3 years from death, after which no original probate proceeding may be initiated — Minn. Stat. 524.3-108. |
| What starts the clock | Two clocks run and the later one controls: (1) the date the will was informally probated (12 months), and (2) the date of the decedent’s death (3 years) — Minn. Stat. 524.3-108(3). Where a formal testacy proceeding is used instead, the trigger is the notice of hearing on the petition for formal probate — objections must be stated in the pleadings before that hearing (Minn. Stat. 524.3-403, 524.3-404), and after the order the 12-month vacation clock runs from entry of the order (Minn. Stat. 524.3-412(3)). |
| Who can contest | Only an “interested person” may petition or object. Minn. Stat. 524.1-201(34) defines “interested person” to include heirs, devisees, children, spouses, creditors, beneficiaries, and any others having a property right in or claim against the estate that may be affected by the proceeding — which covers beneficiaries under a prior or later will. Minnesota expressly includes creditors in the definition. The meaning of “interested person” is determined according to the particular purposes of, and matter involved in, any proceeding, so the court evaluates standing issue by issue. |
| No-contest clause | YES, WITH A PROBABLE-CAUSE EXCEPTION. Minn. Stat. 524.2-517: “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.” So a no-contest (in terrorem) clause is generally given effect in Minnesota, but it cannot be enforced against a contestant who had probable cause to bring the challenge. A parallel provision for trusts appears at Minn. Stat. 501C.1013. |
| What the filing is called | A petition for formal testacy (a “petition for formal probate of will” or a petition to set aside/contest an informally probated will and for adjudication of intestacy) filed under Minn. Stat. 524.3-401 and 524.3-402; where someone else has already petitioned for formal probate, the contest is made by filing an Objection stating the grounds in the pleadings under Minn. Stat. 524.3-404. The Minnesota Judicial Branch publishes a probate Objection form and instructions (form PRO1001). Filed in the county where venue lies under Minn. Stat. 524.3-201 — generally the county of the decedent’s domicile at death. |
| Court | Minnesota District Court, which has exclusive original jurisdiction over probate matters. Larger counties route these to a probate division — Hennepin County Probate/Mental Health Court and Ramsey County Probate Court — while other counties hear probate in the general District Court. There is no separate statewide surrogate’s court in Minnesota. |
| Jury trial | LIMITED — generally NO in a will contest. Minn. Stat. 524.1-306(a) grants a jury trial only where a party has a constitutional right to one on the controverted fact question; Minn. Const. art. I, sec. 4 preserves jury trial for “cases at law,” and the Minnesota Supreme Court has held no jury-trial right attaches to equitable claims. Will contests in Minnesota probate are equitable in nature, so under Minn. Stat. 524.1-306(b) the court may in its discretion call a jury, but that verdict is advisory only and does not bind the court. Confirm the posture of a specific case with the court or a licensed Minnesota attorney. |
| Typical cost | UNVERIFIED — no Minnesota court, statute, or state agency publishes a typical cost range for a contested will case. Costs vary widely with the size of the estate, the grounds raised, discovery, expert testimony, and whether the matter settles. Check with the Minnesota Judicial Branch or a licensed Minnesota attorney for a case-specific estimate. |
The Deadline to Contest a Will in Minnesota
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 Minnesota
Minn. Stat. 524.3-407 names the recognized grounds a contestant may raise: lack of testamentary intent, lack of testamentary capacity, undue influence, fraud, duress, mistake, and revocation. Improper execution / lack of due execution is also contestable because the proponent must make prima facie proof of due execution under Minn. Stat. 524.3-407 and Minn. Stat. 524.2-502 (signed by the testator and by at least 2 witnesses).
Forgery is contestable and is an express exception to the self-proved will presumption under Minn. Stat. 524.3-406.
Who has to prove what: The CONTESTANT carries the burden. Minn. Stat. 524.3-407: “Contestants of a will have the burden of establishing lack of testamentary intent or capacity, undue influence, fraud, duress, mistake or revocation,” and each party bears the ultimate burden of persuasion on matters for which it has the initial burden.
The proponent of the will has the burden of prima facie proof of due execution (and, if also the petitioner, prima facie proof of death and venue); a petitioner seeking to establish intestacy bears prima facie proof of death, venue, and heirship.
On undue influence, Minnesota case law requires the contestant to prove it by CLEAR AND CONVINCING evidence, using the factors set out in In re Estate of Reay/In re Estate of Peterson: opportunity to exercise influence, a confidential relationship between the testator and the alleged influencer, active participation in preparing the will, disinheritance of those the testator would be expected to remember, singularity of the will’s provisions,
and actual exercise of influence or persuasion.
A confidential relationship is one factor supporting a finding of undue influence rather than an automatic statutory burden-shifting presumption. If the will is self-proved, compliance with the signature requirements is conclusively presumed and the other execution requirements are presumed subject to rebuttal, absent proof of fraud or forgery affecting the affidavit — Minn. Stat. 524.3-406.
Who Can Contest a Will in Minnesota
Only an “interested person” may petition or object. Minn. Stat. 524.1-201(34) defines “interested person” to include heirs, devisees, children, spouses, creditors, beneficiaries, and any others having a property right in or claim against the estate that may be affected by the proceeding — which covers beneficiaries under a prior or later will. Minnesota expressly includes creditors in the definition.
The meaning of “interested person” is determined according to the particular purposes of, and matter involved in, any proceeding, so the court evaluates standing issue by issue. Being unhappy with the will is not standing; losing something because of it is. Check the earlier will and the intestate rules for Minnesota before filing, because they decide whether you are an interested person.
No-Contest Clauses in Minnesota
YES, WITH A PROBABLE-CAUSE EXCEPTION. Minn. Stat. 524.2-517: “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.” So a no-contest (in terrorem) clause is generally given effect in Minnesota, but it cannot be enforced against a contestant who had probable cause to bring the challenge.
A parallel provision for trusts appears at Minn. Stat. 501C.1013.
The Steps to Contest a Will in Minnesota
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 (a “petition for formal probate of will” or a petition to set aside/contest an informally probated will and for adjudication of intestacy) filed under Minn. Stat. 524.3-401 and 524.3-402; where someone else has already petitioned for formal probate, the contest is made by filing an Objection stating the grounds in the pleadings under Minn. Stat. 524.3-404.
The Minnesota Judicial Branch publishes a probate Objection form and instructions (form PRO1001). Filed in the county where venue lies under Minn. Stat. 524.3-201 — generally the county of the decedent’s domicile at death.. 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. Minn. Stat. 524.3-1101 authorizes a written compromise agreement resolving a controversy over admission of an instrument to probate, the construction/validity/effect of a probated will, the rights or interests of successors, or estate administration; when approved by the court in a formal proceeding it binds all parties, including persons unborn, unascertained, or who cannot be located, and may bind a trust or an otherwise inalienable interest. Minn. Stat.

524.3-1102 sets the procedure: the written agreement is executed by all competent persons and by parents acting for affected minors, submitted by any interested person, and after notice to all interested persons the court approves it if it finds the contest or controversy is in good faith and the effect on interests represented by fiduciaries is just and reasonable. Court-annexed ADR, including mediation, is also available under Minn. R. Gen.
Prac. 114.
Other Minnesota rules: (1) NO ante-mortem / pre-death will validation in Minnesota — Minnesota is not among the states with a living-probate statute, so a will generally cannot be validated by a court during the testator’s lifetime. (2) Self-proved will presumption — under Minn. Stat.
524.2-504 and 524.3-406, if the will carries a self-proving acknowledgment and witness affidavits, compliance with the signature requirements is CONCLUSIVELY presumed and the remaining execution requirements are presumed subject to rebuttal, without witness testimony, unless there is proof of fraud or forgery affecting the acknowledgment or affidavit — this makes a pure “improper execution” contest very difficult against a self-proved Minnesota will.
(3) Signature on a self-proving affidavit counts as a signature on the will itself if needed to prove due execution — Minn. Stat. 524.2-504.
(4) Minnesota’s two-track system matters: an informally probated will can be challenged later (up to the 12-month/3-year outer limits of 524.3-108), while a formal testacy order is final as to all issues the court considered or might have considered, subject only to appeal and the narrow 12-month vacation route of Minn. Stat. 524.3-412 and 524.3-413.
(5) The 524.3-108 limits do NOT apply to proceedings to construe a probated will, to determine heirs of an intestate, or to determine descent. (6) Contesting a will does not by itself forfeit a bequest where the contestant had probable cause — Minn. Stat. 524.2-517. (7) Minnesota also has a separate proceeding to determine descent for estates where the decedent died more than 3 years before the filing (Minn. Stat.
525.31), which is the usual route once the 3-year probate window has closed.
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: Minnesota 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 Minnesota, 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 Minnesota
A will contest is a lawsuit about the document, not about fairness. When you contest a will in Minnesota, 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 Minnesota 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.
