North Dakota Will Contests

A North Dakota will contest is a formal testacy proceeding in district court: the grounds NDCC 30.1-15-07 names, who may file, and the deadlines.

By Settled Editorial

A North Dakota will contest is a formal testacy proceeding, which NDCC 30.1-15-01(1) defines as litigation to determine whether a decedent left a valid will. An interested person starts it by petition in the district court, a judge decides it after notice and a hearing, and NDCC 30.1-12-08 sets the deadline, which for an informally probated will is the later of twelve months from that probate or three years from the death.

Three features shape a North Dakota contest. The grounds sit in statute, because NDCC 30.1-15-07 names them while assigning the burden of proof, and the list ends with "other cause affecting its validity" rather than closing at revocation. A testator can have a will declared valid during life under chapter 30.1-08.1, which takes the usual contest questions off the table later. And the jury right comes with its own clock: a written demand no later than seven days before the hearing, under NDCC 30.1-15-04.

A contest is litigation with a high bar. The challenger carries the burden of proving a ground the statute names, the deadlines below are strict, a penalty clause can put a gift at risk, and many contests do not succeed.

This page describes the mechanism as the North Dakota Century Code states it. Every section quoted here was read on September 28, 2026, in the chapter files the North Dakota Legislative Council publishes at ndlegis.gov, which the Council says reflect all changes the 69th Legislative Assembly approved in 2025. It is general information and says nothing about whether a challenge fits your family's facts. A licensed North Dakota attorney is the person who answers that, and an early conversation leaves more of the deadline to work with. If the estate has not opened yet, the North Dakota probate process covers the proceeding a contest interrupts.

What a North Dakota Will Contest Is

NDCC 30.1-15-01(1) lets an interested person commence a formal testacy proceeding by filing one of three petitions:

  • To probate a will formally, asking the court to enter an order after notice and hearing, under NDCC 30.1-15-02(1).
  • To set aside an informal probate of a will, or to prevent informal probate of a will that is the subject of a pending application.
  • For an order that the decedent died intestate, under NDCC 30.1-15-02(2).

Under NDCC 30.1-15-01(2), a petition may seek formal probate of a will whether or not that will or a conflicting one has already been informally probated, and the proceeding may, but need not, include a request to appoint a personal representative. That matters when the fight is over the document rather than over who runs the estate.

The reason contests so often arrive late is built into the code. NDCC 30.1-01-06(26) defines informal proceedings as those the court conducts for probate of a will or appointment of a personal representative without notice to interested persons, and NDCC 30.1-02-06 lets the clerk of district court, without a written court order, sign the documents in an uncontested informal probate once at least 120 hours have passed since the death and the other conditions of that section are met. A family can learn about a will after it has already been admitted. The difference between formal versus informal probate is the difference between a case decided with notice and one decided without it.

Filing a formal proceeding changes the estate at once:

  • The court stops acting on informal requests. NDCC 30.1-15-01(3) says that while a formal testacy proceeding is pending, the court shall not act on any application for informal probate of any will of the decedent or for informal appointment of a personal representative.
  • Distribution stops. Under NDCC 30.1-15-01(4), a personal representative appointed earlier must refrain from making any further distribution of the estate once notice of the formal proceeding arrives, unless the petition also asks the court to confirm that earlier informal appointment. A petitioner who wants a different representative may also ask the court to restrain the sitting one and appoint a special administrator. Without that request, or if the court denies it, the sitting representative keeps every other power and duty described in North Dakota executor duties.

A contest is the wrong tool for a complaint about how an estate is being run. NDCC 30.1-16-02 lets any interested person petition for supervised administration at any time, and in an ordinary case the court orders it when it finds supervision necessary under the circumstances. If testacy has not been decided yet, the same section requires the court to adjudicate it in that proceeding, even when the request for supervision is denied.

The Deadline to Contest a North Dakota Will

North Dakota runs two clocks under one section, and the second is why a family that has just learned about an informal probate is often still in time.

SituationDeadlineStatute
Opening any informal probate or formal testacy proceedingNot more than 3 years after the death, subject to the exceptions below30.1-12-08
Contesting a will that was informally probatedThe later of 12 months from that informal probate or 3 years from the death30.1-12-08(3)
An earlier proceeding was dismissed over doubt about the fact of deathAny time after, on a finding that death came before the earlier proceeding and the petitioner did not delay unduly30.1-12-08(1)
Estate of an absent, disappeared, or missing person with a conservatorWithin 3 years after the conservator becomes able to establish the death30.1-12-08(2)
No proceeding of any kind within 3 years of the deathAn informal appointment or formal testacy proceeding may still begin, but the personal representative may possess assets only as needed to confirm title, and only administration-expense claims may be presented30.1-12-08(4)
Construing a probated will, or determining the heirs of an intestateThe limits do not apply30.1-12-08, closing paragraph

Read the second row twice. Because the window runs to whichever date falls later, an informal probate opened near the three-year mark still carries a full twelve months of contest exposure. A personal representative who treats the file as closed at the three-year anniversary has read half the subsection. The same dates sit beside every other dated duty on the North Dakota probate timeline.

Online summaries of North Dakota law put the contest window at "three years from admission" or "three months after the reading of the will." Neither phrase appears in the section. The text above is the rule.

What the Late-Filing Row Does and Does Not Allow

NDCC 30.1-12-08(4) is narrower than it first looks. It lets an informal appointment or a formal testacy proceeding begin after three years only when no proceeding concerning the succession or estate administration happened during the three-year period. A personal representative appointed that way has no right to possess estate assets beyond what it takes to confirm title in the successors, and claims other than expenses of administration may not be presented. A late filing can settle who owns what. It does not reopen the estate to creditors.

A separate exception, NDCC 30.1-12-08(5), lets a formal testacy proceeding begin at any time after three years to establish an instrument that controls property passing from someone other than the decedent, such as property the will appoints under a power of appointment.

Reopening an Order That Already Entered

A formal testacy order is final as to all persons on every issue the court considered or might have considered about whether the decedent left a valid will and who the heirs are, subject to appeal. NDCC 30.1-15-12 then opens two narrow doors:

  • Under 30.1-15-12(1), the court shall entertain a petition to modify or vacate its order and probate another will if the proponents of the later-offered will were unaware of its existence at the time of the earlier proceeding, or were unaware of that proceeding and received no notice of it except by publication.
  • Under 30.1-15-12(2), where intestacy was ordered, the determination of heirs may be reconsidered for a person who was omitted and who was unaware of the relationship, unaware of the death, or given no notice of any proceeding except by publication.

NDCC 30.1-15-12(3) caps both with three outer limits, and the earliest governs: the entry of an order approving final distribution, or six months after a closing statement is filed; the date under 30.1-12-08 when an original proceeding to probate a will is no longer possible; or twelve months after entry of the order the petitioner wants vacated. Separately, NDCC 30.1-15-13 lets the court modify or vacate an order in a formal testacy proceeding for good cause shown, within the time allowed for appeal.

Who Can Contest a North Dakota Will

Only an interested person may commence a formal testacy proceeding. NDCC 30.1-01-06(27) defines the term for the probate code, and for a decedent's estate the list reads: heirs and devisees; children; spouses; creditors; beneficiaries; any individual having a property right in or claim against a trust estate or the estate of a decedent, ward, or protected person; a person having priority for appointment as personal representative; and other fiduciaries representing interested persons.

The definition closes with a sentence that decides more arguments than the list does: the meaning as it relates to particular persons may vary from time to time and must be determined according to the particular purposes of, and matter involved in, any proceeding. Standing is answered proceeding by proceeding rather than once for the whole estate. NDCC 30.1-01-06 was last amended by 2025 Senate Bill 2291, so a summary of the definitions section written before that session is worth checking against the current text rather than quoted from memory.

Working from that definition, the people who most often have a stake in setting a will aside are:

  • Heirs at law, the relatives who would take under North Dakota intestate succession if no valid will governs.
  • Devisees under an earlier will, whose share was larger before the challenged document appeared.
  • Devisees under the challenged will, when an earlier document treated them better.
  • A person with priority for appointment, since NDCC 30.1-12-08(3) frames the contest as a proceeding to secure appointment of the person with legal priority if it succeeds.

The Grounds North Dakota Law Names

NDCC 30.1-15-07 states the grounds in a single sentence while assigning who must prove what: contestants of a will have the burden of establishing lack of testamentary intent or capacity, undue influence, fraud, duress, mistake, revocation, or other cause affecting its validity.

Lack of Testamentary Intent or Capacity

Intent asks whether the decedent meant the paper to operate as a will at all. Capacity asks whether the decedent had the mental ability to make one when signing. The section names both and leaves their content to the courts. Chapter 30.1-08 opens with NDCC 30.1-08-01: any adult who is of sound mind may make a will. NDCC 14-10-02 sets adulthood at eighteen, and a contestant carries the burden of showing the sound-mind condition was missing.

Undue Influence, Fraud, and Duress

These three attack how the will came to say what it says. Undue influence claims that someone substituted their wishes for the testator's. Fraud claims the testator was deceived about the document or about facts that shaped it. Duress claims the testator was forced. The statute names each ground and does not define any of them, so the proof needed for each comes from North Dakota case law, which is a question for the attorney handling the case.

Mistake and Revocation

A contestant can argue the will reflects a mistake, or that the testator revoked it. Revocation often surfaces when a later will turns up. NDCC 30.1-15-07 settles the order of battle for that case: if a will is opposed by a petition to probate a later will revoking it, the court determines first whether the later will is entitled to probate. If a will is opposed by a petition for a declaration of intestacy, the court determines first whether the will is entitled to probate.

Improper Execution

A signing defect is argued against the proponent's burden rather than proved by the contestant. NDCC 30.1-15-07 gives proponents of a will the burden of establishing prima facie proof of due execution in all cases. What that proof looks like depends on how the will was signed, under NDCC 30.1-15-06:

How the will was signedWhat happens when execution is contestedSubsection
Self-proved under NDCC 30.1-08-04Meets the execution requirements on filing, without witness testimony, unless there is evidence of fraud or forgery affecting the acknowledgment or affidavit30.1-15-06(1)
Acknowledged before a notary but not self-provedA rebuttable presumption that the will was properly executed, on filing30.1-15-06(2)
Witnessed only, not notarized or self-provedTestimony of at least one attesting witness is required if a witness is in North Dakota, competent, and able to testify; other evidence, including a witness affidavit, can also prove it, and a signed attestation clause raises a rebuttable presumption that the events it recites occurred30.1-15-06(3)

The signing rules themselves, including the notary option and handwritten wills, are covered in what makes a will valid. North Dakota has no harmless error rule in chapter 30.1-08, so a will that misses a required step gets no rescue on proof of intent alone. The difference between a missing statutory step and a formality the statute excuses is one of the questions a court weighs when execution is disputed.

The Separate Rule for a Killer

A beneficiary's role in the death is not a formal ground to set a will aside, but it can strip that person's gifts. NDCC 30.1-10-03(2) says an individual who intentionally and feloniously kills the decedent forfeits all benefits under Title 30.1 with respect to the estate, and 30.1-10-03(3) revokes revocable gifts to the killer and the killer's nominations as personal representative, trustee, or agent. Under 30.1-10-03(7), a final conviction settles the question. Without one, the court decides it on an interested person's petition under the preponderance of the evidence standard. North Dakota's section reaches killing only; it does not add the financial-exploitation forfeiture some states have written into the same Uniform Probate Code provision.

No-Contest Clauses in North Dakota

Some wills say a beneficiary who challenges the document loses their gift. NDCC 30.1-20-05 limits that threat: 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.

Two consequences follow. Where probable cause existed, the section makes the penalty clause unenforceable, even if the contest itself fails. Where it did not, the clause can operate against the gift it targets. The section does not define probable cause, so whether a given challenge clears that bar is a judgment a licensed North Dakota attorney makes on the actual evidence.

Heading Off a Contest During Life

North Dakota offers a tool most states do not. Chapter 30.1-08.1 lets the person who signed a will ask the court, while still alive, to declare it valid.

  • What it covers. NDCC 30.1-08.1-01 lets a testator bring a proceeding under chapter 32-23, the declaratory judgment chapter, for a judgment declaring the will valid as to the signature, the required number of witnesses and their signatures, and the testator's testamentary capacity and freedom from undue influence.
  • Who must be joined. Under NDCC 30.1-08.1-02, every beneficiary named in the will and all the testator's present intestate successors must be named parties and served under Rule 4 of the North Dakota Rules of Civil Procedure.
  • What a finding does. Under NDCC 30.1-08.1-03, if the court finds the will properly executed and the testator had the requisite capacity and freedom from undue influence, it declares the will valid and orders it placed on file. For purposes of NDCC 30.1-12-02, that finding is an adjudication of probate, and the will binds in North Dakota unless the testator signs a new will and brings a new proceeding.
  • Where its facts can be used. NDCC 30.1-08.1-04 limits the findings to proceedings in North Dakota that determine the validity of a will.

A family worried about a later fight can raise this with the drafting attorney. It does not answer every ground: fraud, duress, mistake, and a later revocation sit outside the list in 30.1-08.1-01.

How a North Dakota Contest Moves Through Court

NDCC 30.1-02-04 applies the Rules of Civil Procedure, including the rules on vacation of orders and appellate review, to formal proceedings under Title 30.1 unless the title says otherwise.

Filing and Notice

NDCC 30.1-15-02(1) tells a petition for formal probate what to contain: a request for an order as to testacy in relation to a particular instrument and determining the heirs, the statements an informal application would carry, and a statement of whether the original will is in the court's possession or accompanies the petition. If neither the original nor an authenticated copy from another jurisdiction is available, the petition must state the contents of the will and say that it is lost, destroyed, or otherwise unavailable. That is the route for a lost-will case.

The court then fixes a time and place of hearing under NDCC 30.1-15-03(1). The petitioner gives notice to the surviving spouse, children, and other heirs; to the devisees and executors named in any will probated or offered for probate in the county, or known to have been offered elsewhere; to any personal representative whose appointment has not ended; and to anyone who filed a demand for notice. The petitioner also gives notice by publication to unknown persons and to known persons whose addresses are unknown.

NDCC 30.1-03-01 sets the method. Notice is mailed at least fourteen days before the hearing by certified or ordinary first-class mail, or delivered personally at least fourteen days before. Where an address or identity cannot be found with reasonable diligence, the notice runs once a week for three consecutive weeks in a newspaper of general circulation in the county of the hearing, with the last publication at least ten days before the hearing. The court may order a different method or time for good cause, and proof of notice must be filed on or before the hearing.

The code also provides a way onto the notice list early. NDCC 30.1-13-04 lets anyone with a financial or property interest in the estate file a demand for notice at any time after the death. After that filing, no order or filing to which the demand relates may be made or accepted without notice to the demandant.

Venue follows NDCC 30.1-13-01: the county where the decedent was domiciled at death, or, for a nonresident, any county where the decedent's property was located. Later proceedings stay in the court where the first one began unless it was transferred. The North Dakota probate courts page lists the district court for each county.

Objections and the Jury Demand

Anyone who opposes the will has to say so on the record. NDCC 30.1-15-04 requires any party to a formal proceeding who opposes probate of a will, for any reason, to state the objections in the pleadings.

The same section carries the jury right and its deadline. 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 with the court, a written demand for jury trial. The demand must be attached to the pleading of the party that raises the issues of fact, and it may not be served and filed later than seven days before the time set for the hearing. The section provides no route for a demand served or filed after that date.

Appeals

NDCC 30.1-02-06.1 sends appeals to the North Dakota Supreme Court under the rules for appeals in equity cases from the district court, except that where a jury trial was had as a matter of right, the rules on scope of review in jury cases apply.

What Happens If the Contest Succeeds

If the challenged will falls, the estate passes under an earlier valid will if one exists, and otherwise under North Dakota intestate succession. A surviving spouse's homestead, exempt property, and family allowance sit outside the fight over the will's terms, and North Dakota surviving spouse rights covers them. A contest also stretches the calendar for everyone waiting on a distribution.

A will contest does not reach property held in a revocable trust. Chapter 59-10.1 governs a trust contest, and NDCC 59-10.1-03 bars one after the earliest of 120 days after the trustee's notice, three years after the settlor's death, the will-contest period when the trust was revocable at death and named in the settlor's last will, or the date the right was otherwise precluded. How a North Dakota revocable living trust works covers the trust side.

Before any of that, four narrow questions decide whether a North Dakota contest is even available: whether the person filing is an interested person under NDCC 30.1-01-06(27), whether the NDCC 30.1-12-08 window is still open, whether the facts line up with a ground NDCC 30.1-15-07 names, and whether the will carries an NDCC 30.1-20-05 penalty clause. A licensed North Dakota attorney answers all four against the actual documents.
