Contest a Will in North Dakota: At a Glance
Here are the North Dakota facts that decide whether you can contest a will in North Dakota:
| Deadline to contest | For a will admitted through INFORMAL probate, a contest must be commenced within the later of 12 months after the informal probate or 3 years after the decedent’s death — N.D.C.C. 30.1-12-08 (UPC 3-108). For a will admitted through FORMAL probate, written objections must be filed before or at the formal testacy hearing (jury demand no later than 7 days before the hearing) — N.D.C.C. 30.1-15-04 (UPC 3-404); once entered, a formal testacy order is final as to all persons under N.D.C.C. 30.1-15-12 (UPC 3-412) and can only be reopened on the narrow grounds listed there. Outside limit for any probate/testacy proceeding: 3 years after death — N.D.C.C. 30.1-12-08. |
| What starts the clock | Two clocks run and the later one controls in the informal-probate track: (1) the date the will was informally admitted to probate by the registrar (12 months), and (2) the date of the decedent’s death (3 years). In the formal-probate track the trigger is the date set for the formal testacy hearing — objections must be on file before the court enters its testacy order. Receipt of the personal representative’s notice or a filed Demand for Notice under N.D.C.C. 30.1-13-04 does not by itself shorten the statutory 12-month/3-year period, but it is what alerts an interested person that the clock is running. |
| Who can contest | Only an “interested person” may petition or object. N.D.C.C. 30.1-01-06(24) defines interested person to include heirs, devisees, children, spouses, creditors, beneficiaries, and any other person 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 statute expressly says the meaning “may vary from time to time and must be determined according to the particular purposes of, and matter involved in, any proceeding” — so a beneficiary under a prior or later will, an intestate heir, and in some matters a creditor may each qualify. |
| No-contest clause | YES, enforced but with a probable-cause exception. N.D.C.C. 30.1-20-05 (UPC 2-517/3-905): “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 contest brought without probable cause can still trigger forfeiture. |
| What the filing is called | A “Petition for Formal Testacy” (Petition for Formal Probate of Will / to set aside probate) under N.D.C.C. 30.1-15-01 and 30.1-15-02, or, where a formal proceeding is already pending, “Written Objections to Probate” under N.D.C.C. 30.1-15-04. Filed with the clerk of the North Dakota district court in the county where the estate is being administered (venue: N.D.C.C. 30.1-13-01). |
| Court | North Dakota district court. North Dakota has no separate probate or surrogate court — the district courts have original and exclusive subject-matter jurisdiction over all estate and probate matters under N.D.C.C. 30.1-02-02, and formal probate is heard by a district court judge. |
| Jury trial | YES. N.D.C.C. 30.1-15-04 (3-404) provides that in a contested formal testacy proceeding any party is entitled to a jury trial of all issues of fact by serving on all appropriate parties and filing a written demand for jury trial; the demand must be affixed to the pleading raising the issues of fact and may not be served and filed later than 7 days before the time set for hearing. This is a North Dakota addition to the uniform text. Missing the 7-day deadline waives the jury. |
| Typical cost | UNVERIFIED — North Dakota courts and the State Bar Association of North Dakota do not publish a cost range for contested will cases, and attorney fees vary by county, hourly rate, and whether the matter goes to a jury. North Dakota district court civil filing fees are set by N.D.C.C. 27-05.2-03. Check with the clerk of district court or a licensed North Dakota attorney for current figures. |
The Deadline to Contest a Will in North Dakota
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 North Dakota
Set out in N.D.C.C. 30.1-15-07 (UPC 3-407) — lack of testamentary intent, lack of testamentary capacity, undue influence, fraud, duress, mistake, revocation, or “other cause affecting its validity.” Improper execution/forgery is reached through the proponent’s burden under the same section (proponents must prove due execution per N.D.C.C. 30.1-08-02, the signing and witnessing requirements). Testamentary capacity requires the testator be 18 or older and of sound mind — N.D.C.C. 30.1-08-01.
Who has to prove what: Split under N.D.C.C. 30.1-15-07 (3-407). Proponents of the will have the burden of establishing prima facie proof of due execution in all cases, and of death, venue, and jurisdiction where relevant. Contestants then carry the burden of establishing lack of testamentary intent or capacity, undue influence, fraud, duress, mistake, or revocation.
Each party bears the ultimate burden of persuasion on the matters for which it has the initial burden of proof. The standard is the ordinary civil preponderance of the evidence, and North Dakota Supreme Court decisions treat testamentary capacity and undue influence as findings of fact reviewed for clear error.
North Dakota case law recognizes that a confidential or fiduciary relationship combined with suspicious circumstances can support an inference of undue influence, but North Dakota does not shift the statutory burden off the contestant by statute — the contestant retains it. A self-proved will under N.D.C.C. 30.1-08-04/30.1-08-05 satisfies the execution requirements without live testimony from the witnesses, so a contestant attacking a self-proved will must overcome that presumption.
Where a later will is offered to revoke an earlier one, the court determines first whether the later will is entitled to probate (30.1-15-07).
Who Can Contest a Will in North Dakota
Only an “interested person” may petition or object. N.D.C.C. 30.1-01-06(24) defines interested person to include heirs, devisees, children, spouses, creditors, beneficiaries, and any other person 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 statute expressly says the meaning “may vary from time to time and must be determined according to the particular purposes of, and matter involved in, any proceeding” — so a beneficiary under a prior or later will, an intestate heir, and in some matters a creditor may each qualify. Being unhappy with the will is not standing; losing something because of it is.
Check the earlier will and the intestate rules for North Dakota before filing, because they decide whether you are an interested person.
No-Contest Clauses in North Dakota
YES, enforced but with a probable-cause exception. N.D.C.C. 30.1-20-05 (UPC 2-517/3-905): “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 contest brought without probable cause can still trigger forfeiture.
The Steps to Contest a Will in North Dakota
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” (Petition for Formal Probate of Will / to set aside probate) under N.D.C.C.
30.1-15-01 and 30.1-15-02, or, where a formal proceeding is already pending, “Written Objections to Probate” under N.D.C.C. 30.1-15-04. Filed with the clerk of the North Dakota district court in the county where the estate is being administered (venue: N.D.C.C. 30.1-13-01).. 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. N.D.C.C. 30.1-20-12 (UPC 3-912) allows competent successors to agree among themselves in a written contract executed by all affected persons 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 the duty to administer the estate for creditors, pay taxes and administration costs, and protect non-party successors.

Rights of creditors and taxing authorities are not affected. In addition, N.D.C.C. 30.1-15-11 (UPC 3-411) permits compromise of controversies over testacy and will construction to be approved by court order binding on all parties including unborn, unascertained, and incompetent persons, and North Dakota district courts may order mediation or other alternative dispute resolution in civil cases.
Other North Dakota rules: (1) No ante-mortem/pre-death will validation — North Dakota has no statute allowing a testator to have a will judicially validated during life; contests happen only after death. (2) Jury trial as of right in contested formal testacy, with a hard 7-day-before-hearing written demand deadline — a North Dakota-specific addition to UPC 3-404 that many UPC states do not have. (3) Self-proved wills — N.D.C.C.
30.1-08-04 (2-504) and 30.1-08-05 (2-505) let a will be self-proved by acknowledgment before a notary at signing or later; a self-proved will is conclusive as to signature requirements absent evidence of fraud or forgery, so a contestant generally cannot attack execution formalities alone. (4) Holographic wills are valid in North Dakota if the signature and material portions are in the testator’s handwriting, whether or not witnessed — N.D.C.C. 30.1-08-02(2).
(5) Electronic wills are recognized — North Dakota enacted the Uniform Electronic Wills Act at N.D.C.C. ch. 30.1-08.1, adding execution-validity questions unique to those instruments. (6) A Demand for Notice may be filed under N.D.C.C. 30.1-13-04 by any interested person, which forces notice of any order or filing in the estate and is the practical way to avoid being surprised by an informal probate.
(7) There is no separate probate court — district court handles everything, and informal probate can be opened by a registrar with no hearing at all, so many contests begin only after an interested person learns of the informal admission. (8) Deposit of a will with the court during the testator’s lifetime is permitted under N.D.C.C. 30.1-13-02 (2-515).
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: North Dakota 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 North Dakota, 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 North Dakota
A will contest is a lawsuit about the document, not about fairness. When you contest a will in North Dakota, 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 North Dakota 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.
