North Dakota Prenuptial Agreement
North Dakota prenuptial agreements are governed by the UPMAA (N.D.C.C. ch. 14-03.2), adopted by only one other state (Colorado). Courts apply single review only — unconscionability is assessed at signing, not additionally at divorce — and challengers must prove one of four statutory defects: involuntary execution, no access to counsel, missing notice-of-rights waiver, or inadequate disclosure. Spousal support waivers are enforceable; the alimony floor is "substantial hardship" (N.D.C.C. § 14-03.2-08(5)–(6)), likely slightly above public assistance eligibility.
Bottom line: North Dakota earns an A- grade. Single review, a four-part challenge standard, and a well-defined alimony floor make North Dakota one of the stronger states for prenup enforceability.

Uniform Premarital and Marital Agreements Act (UPMAA) N.D.C.C. ch. 14-03.2
Separate Property
All assets can remain separate property, avoiding costly divorce settlements. Joint assets and debts titled in both names can be split 50/50 according to a prenuptial agreement.
Unconscionability Single Review (Pro-Prenup)
North Dakota reviews prenuptial agreements for unconscionability ONLY at execution (signing), not at enforcement (divorce). UPMAA eliminated the prior three-time review (execution, separation, enforcement) that produced cases like Sailer and Lutz, providing greater certainty and discouraging litigation challenges.
Unconscionability Standard—N.D.C.C. § 14-03.2-08 Four-Prong Test
A prenup is unenforceable if the challenging party proves: (1) involuntary execution or duress; (2) lack of access to independent legal representation; (3) absence of a notice-of-rights waiver where the party was unrepresented; OR (4) inadequate financial disclosure without a valid written waiver.
Limited Hardship Safety Valve—N.D.C.C. § 14-03.2-08(5)–(6)
Courts may refuse to enforce a single term, like a waiver or modification of alimony, if unconscionable at signing OR causing "substantial hardship" from a post-signing material change. For alimony, courts can rewrite support up to a hardship floor — covering disability, serious illness, or primary caregiving — but not marital lifestyle. Untested in ND; safest practice is a modest scheduled alimony benefit with "hardship" contractually defined.
Timing
No minimum specified, but we recommend signing the prenup 60+ days before the wedding, with both parties having 2-3 weeks to review the final version to minimize challenge risk. Reach out to an attorney at least 4-6 months before the wedding with your draft prenup. Better yet, sign the prenup before proposing. Olson (2024) enforced an agreement signed two days pre-wedding, but earlier signing remains the safer practice.
Independent Counsel
UPMAA requires that each party had access to independent legal representation. If a party was unrepresented, a separate written notice-of-rights waiver is required. In practice, retaining separate counsel is the cleanest path to enforceability.
Financial Disclosure
Reasonable disclosure of property, debts, and income required under N.D.C.C. § 14-03.2-08, or a valid written waiver. PerfectPrenup includes both.
Moderate Burden to Challenge
Challenging party must prove one of the four statutory defects by a preponderance of the evidence. North Dakota courts under UPMAA apply the statutory test directly and do not import equitable second-look doctrines from prior case law.
Child Support and Custody
Child support and custody clauses are unenforceable and could undermine the entire agreement. Do not include.
North Dakota Prenuptial Agreement Court Cases
Reiser v. Reiser, 2001 ND 6, 621 N.W.2d 348
Court enforced the prenup's reservation of husband's retirement account "as of 10-05-95" but held the appreciation in the account during marriage was marital property subject to equitable distribution, because the agreement used a date-specific valuation rather than a categorical exclusion.
Jangula v. Jangula, 2005 ND 203, 706 N.W.2d 85
Prenup was held inapplicable to the marital home because husband had used premarital funds (CRP and farm insurance proceeds) commingled with marital purchase funds and had executed a quit claim deed converting the home to joint tenancy, defeating the agreement's separate-property provisions.
Sailer v. Sailer (Sailer I), 2009 ND 73, 764 N.W.2d 445
Court reversed enforcement and remanded for unconscionability findings where wife was left with no assets, no spousal support, and on public assistance after a 15-year marriage with three children, holding the trial court must make complete factual findings on the parties' relative property values and the spouse's foreseeable needs at the time of enforcement.
Estate of Lutz, 1999 ND 121, 595 N.W.2d 590 (interim)
Court dismissed an interlocutory appeal challenging the trial court's invocation of N.D.C.C. § 14-03.1-06(2) (requiring the estate to provide supplemental support to keep the surviving spouse off public assistance) as improvidently certified under Rule 54(b), leaving in place the lower court's modification of the agreement's effect.
Olson v. Olson, 2024 ND 224
Court affirmed enforcement of a prenup signed two days before the wedding under the UPMAA despite a 30:1 net-worth disparity ($11.59M vs. $387K), finding the wife had access to independent counsel, received adequate disclosure, voluntarily consented, and the agreement was not substantively unconscionable.
Tschider v. Tschider, 2019 ND 112, 926 N.W.2d 126
Court reversed a $6,500/month-for-5-years-then-$4,000/month-for-2-years spousal support award, holding the prenup's spousal support waiver was enforceable and not unconscionable where the wife left the marriage with roughly $3M of a $14M estate.
Sailer v. Sailer (Sailer II), 2010 ND 185, 788 N.W.2d 604
On remand from Sailer I, the Court again reversed, holding the trial court still failed to make required findings about the wife's earning capacity and foreseeable needs as of the date of divorce — but the agreement itself remained presumptively enforceable subject to those findings.
Brummund v. Brummund, 2010 ND 119, 785 N.W.2d 182
Court enforced a prenup's broad separate-property language as covering the appreciation in value of husband's premarital farmland during the marriage, distinguishing Reiser because the agreement contained no date-specific valuation reservation.
Binek v. Binek, 2004 ND 5, 673 N.W.2d 594
Court enforced a prenup signed two days before the wedding despite a roughly 20:1 asset disparity ($600K vs. $30K), finding voluntary execution and adequate awareness of the other spouse's finances, while remanding for reconsideration of spousal support to avoid public-assistance eligibility.
Estate of Lutz, 2000 ND 226, 620 N.W.2d 589 (Lutz II)
Court affirmed enforcement of the premarital agreement against the surviving spouse, holding that lack of independent counsel is a significant factor but not a prerequisite to enforceability and that the three-times unconscionability framework (execution, dissolution, enforcement) governs the analysis.
Estate of Lutz, 1997 ND 82, 563 N.W.2d 90 (Lutz I)
Foundational case establishing that under the UPAA an agreement may be voluntarily and validly executed yet still be substantively unconscionable as enforced, with unconscionability turning on factual findings about relative property values, financial circumstances, and ongoing needs — remanded for those findings.
5-Step Checklist: How to Sign & Execute a Prenup in North Dakota
Step 1: Download and read the North Dakota prenuptial agreement
Start with our free template. It is written for North Dakota-specific statutes and case law under N.D.C.C. ch. 14-03.2 (Uniform Premarital and Marital Agreements Act). Read it in full — know what you are getting into legally with marriage. The 15+ pages is written thoroughly to include rebuttals to common legal challenges and fallback provisions.
Step 2: Draft changes on your own
See a clause you don't like? Copy it into an AI like Claude, explain what you'd like to change or what you want the clause "to do." Save any changes as a separate alternate version — don't overwrite the original. Bring both versions to your attorney review. Note: AI is often gender-biased and crafts terms beyond what is legally required. Push back on its output.
Step 3: Find a matrimonial or divorce lawyer in North Dakota
Find a matrimonial or divorce attorney in your state. Avvo, Findlaw, and Justia are good. Look for someone with 10+ years experience. Call or email and ask them how much to review your draft prenup and help with signing. Send them your draft.
Step 4: Meet your lawyer 4–6 months before the wedding
Our recommendation: sign the prenup before proposing. That way, you both get the legal work out of the way, and you know this is the right person to marry. Already proposed? 4–6 months before the wedding should leave you enough time to give your spouse 1–2 weeks to review the final draft and have it signed 60+ days before the wedding. North Dakota's UPMAA does not impose a minimum waiting period, and Olson (2024) enforced an agreement signed two days pre-wedding — but voluntariness and access to counsel are statutory defects, so earlier signing remains the safer practice.
Step 5: Review and sign the prenup with your attorney
Both attorneys present can serve as the two witnesses and notarize on the spot, satisfying all requirements in one signing ceremony. We HIGHLY recommend having the prenup reviewed and signed with an attorney; under UPMAA, if a party is unrepresented, a separate written notice-of-rights waiver is required. If you don't have an attorney, you at least need the signatures to be notarized. Each party keeps a signed original, and so should each party's attorney.
North Dakota Prenuptial Agreement: Frequently Asked Questions (2026)
1. Are prenuptial agreements enforceable in North Dakota?
Yes. North Dakota enforces prenuptial agreements under the Uniform Premarital and Marital Agreements Act (UPMAA), codified at N.D.C.C. ch. 14-03.2, effective August 1, 2013. North Dakota and Colorado are the only two states to have adopted UPMAA. The statute creates one of the most pro-enforcement frameworks in the country: unconscionability is assessed only at signing (not at divorce), and the challenging party bears the burden of proving a specific statutory defect.
2. How much does a prenup cost in North Dakota?
A North Dakota attorney typically charges $1,500–$4,000 per party for a custom prenuptial agreement, with complex or high-net-worth agreements running $5,000–$10,000+. Using a template (like PerfectPrenup) plus attorney review at signing typically costs $500–$1,000 per party. Each party needs their own attorney, so double the per-party figure for total household cost.
3. What makes a prenup invalid in North Dakota?
Under N.D.C.C. § 14-03.2-08, a prenup is unenforceable only if the challenging party proves one of four statutory defects: (1) involuntary execution or duress; (2) lack of access to independent legal representation; (3) absence of a notice-of-rights waiver where the party was unrepresented; or (4) inadequate financial disclosure without a valid written waiver. Substantive unfairness alone is not grounds for challenge — the agreement must fail one of these four procedural tests.
4. Do both spouses need a lawyer for a prenup in North Dakota?
Not strictly required, but each party must have had access to independent counsel under the UPMAA. If a party signs without a lawyer, a separate written notice-of-rights waiver is required under N.D.C.C. § 14-03.2-08(3). This waiver must include conspicuous language warning the signer they may be giving up rights to support, property, and legal fees. Missing this waiver is a standalone ground for invalidation. Retaining separate counsel eliminates this requirement entirely and is the safest path.
5. How long before the wedding should a prenup be signed in North Dakota?
No statutory minimum. Olson v. Olson (2024 ND 224) enforced a prenup signed two days before the wedding under the UPMAA, and Binek v. Binek (2004 ND 5) enforced one signed two days before the wedding under the prior UPAA. But voluntariness and access to counsel are statutory defects, so earlier signing reduces challenge risk. We recommend signing 60+ days before the wedding, with each party having 2–3 weeks to review the final version. Reach out to an attorney 4–6 months before the wedding. Better yet, sign before proposing.
6. Can a prenup waive alimony or spousal support in North Dakota?
Yes, but with a limited safety valve. Under N.D.C.C. § 14-03.2-08(5), if an alimony waiver would cause a party to become eligible for public assistance at the time of divorce, the court can order support sufficient to avoid that eligibility. Separately, under § 14-03.2-08(6)(b), the court may refuse to enforce any single term — including an alimony waiver — if enforcement would cause "substantial hardship" from a material change in circumstances after signing. A modest scheduled alimony benefit is safer than a full waiver, and contractually defining "substantial hardship" in the agreement is the best practice.
7. Does North Dakota review prenups at signing or at divorce?
Signing only. This is one of the UPMAA's biggest advantages over the prior UPAA, which allowed unconscionability challenges at three points: execution, separation, and enforcement. Under N.D.C.C. § 14-03.2-08(6)(a), substantive unconscionability is assessed as of the date of signing. The only post-signing review is narrow: a court may refuse to enforce a single term if it would cause "substantial hardship" from a material change in circumstances (§ 14-03.2-08(6)(b)), or if an alimony waiver would put a party on public assistance (§ 14-03.2-08(5)). This single-review framework gives North Dakota prenups significantly more durability than agreements in states that apply a "second look" at divorce.
8. Can a prenup protect a business or inheritance in North Dakota?
Yes — and in North Dakota, protection is especially important. Unlike most states, North Dakota is a "kitchen sink" equitable distribution state: courts can divide all property held by either spouse, including assets acquired before marriage, inherited during the marriage, and gifts. Inheritances are not automatically protected in a North Dakota divorce. Without a prenup, a court applying the Ruff-Fischer guidelines has discretion to award part or all of an inheritance or business to the other spouse. A properly drafted prenup under the UPMAA removes this discretion by designating specific assets as separate property.
9. Can a prenup protect farmland in North Dakota?
Yes, but drafting matters. In Brummund v. Brummund (2010 ND 119), the court enforced a prenup's broad separate-property language as covering the appreciation in value of premarital farmland during the marriage. In Reiser v. Reiser (2001 ND 6), the court held that a date-specific reservation ("as of 10-05-95") only protected the value at that date, leaving appreciation as marital property. The lesson: use categorical language designating the farmland and all appreciation, proceeds, and reinvestments as separate property — never a date-specific valuation. Avoid commingling farm funds with joint accounts; in Jangula v. Jangula (2005 ND 203), commingling premarital funds and executing a quit claim deed to joint tenancy defeated the prenup's protections entirely. The same principles apply to CRP payments, crop insurance proceeds, oil royalties, and mineral rights.
10. What financial disclosure is required for a North Dakota prenup?
N.D.C.C. § 14-03.2-08(4) requires that each party receive a reasonably accurate description and good-faith estimate of value of the other party's property, liabilities, and income. Alternatively, a party may sign a separate written waiver of disclosure, or the court may find the party had adequate knowledge from other sources (for example, years of cohabitation and shared financial management, as in Olson (2024)). Best practice is full schedules of assets, liabilities, and income attached as exhibits — even if a waiver is also signed. Inadequate disclosure is one of the four statutory grounds for invalidation, and it is the most commonly litigated.
11. Can child support or custody be included in a North Dakota prenup?
No. Under N.D.C.C. § 14-03.2-09(2)(a), any term that adversely affects a child's right to support is unenforceable. Subsection (3) provides that terms defining parental rights and responsibilities are not binding on the court. Including child support or custody provisions in a prenup risks undermining the credibility of the entire agreement. Leave these issues out entirely.
12. Are prenups signed before 2013 still enforceable in North Dakota?
Yes, but they are governed by the prior Uniform Premarital Agreement Act (former N.D.C.C. ch. 14-03.1) and its three-time unconscionability review — at execution, at separation, and at enforcement. This is a more challenger-friendly standard. Cases like Sailer v. Sailer (2009 ND 73), Binek v. Binek (2004 ND 5), and Estate of Lutz (1997 ND 82) remain controlling for pre-2013 agreements. Agreements signed on or after August 1, 2013 are governed by the UPMAA's single-review framework. If you signed a prenup before 2013, consider executing a postnuptial amendment under the UPMAA to update the enforceability standard.
13. Can a prenup be modified or revoked after marriage in North Dakota?
Yes. Under N.D.C.C. ch. 14-03.2, a premarital agreement can be amended or revoked after marriage by a written agreement signed by both parties. The UPMAA calls such post-marriage agreements "marital agreements" and subjects them to the same enforceability standards as prenups — including the requirements for disclosure, access to counsel, and the notice-of-rights waiver for unrepresented parties. North Dakota's adoption of the UPMAA (which expressly covers marital agreements, not just premarital ones) gives postnuptial agreements the same statutory footing as prenups. This is not true in every state.
14. What happens in a North Dakota divorce without a prenup?
Without a prenup, North Dakota courts divide all property under the Ruff-Fischer guidelines — a 12-factor equitable distribution test applied at the court's discretion. North Dakota is a "kitchen sink" state, meaning everything is on the table: premarital assets, inheritances received during the marriage, gifts, retirement accounts, farmland, and business interests. The court starts with a presumption of equal division but can depart based on marriage duration, earning ability, health, conduct, and each spouse's contributions. Unlike many states, North Dakota does not automatically protect separate or inherited property. A prenup is the only reliable way to remove specific assets from this discretionary analysis.
