New Hampshire Prenuptial Agreement

‍

In re Estate of Hollett, 150 N.H. 39 (2003)

NH Supreme Court invalidated a prenup signed on the wedding morning by a wife (age ~28, high-school dropout with minimal assets) where the husband (age ~58, ~$6M estate) presented it less than two days before a 200-guest wedding and provided her an inexperienced attorney with no time to verify financials, holding that vast bargaining-power disparities require a "high standard of procedural fairness."

‍

MacFarlane v. Rich, 132 N.H. 608 (1989)

‍Foundational case establishing the three-prong invalidation test (fraud/duress/nondisclosure, unconscionability, or changed circumstances) and holding that prenup support provisions may be reformed where enforcement would cause "unconscionable hardship" due to unforeseen changed circumstances, while requiring spouses to exercise "the highest degree of good faith, candor and sincerity."

‍

In the Matter of Yannalfo, 147 N.H. 597 (2002)

‍NH Supreme Court enforced a narrow prenup signed a day before the wedding by two postal-service spouses covering only the husband's $70K down payment and wife's $5K closing-cost contribution on a $183,150 home, rejecting per se invalidation of last-minute agreements and holding that the threat that the marriage would not occur, standing alone, is insufficient to establish duress.

‍

In re Estate of Wilber, 165 N.H. 246 (2013)

‍NH Supreme Court reversed the probate court and enforced a postnup between spouses married ~50 years (despite no financial disclosures and no attorneys) where the wife's estate failed to prove fraud, duress, or unfairness, formally recognizing postnuptial agreements as enforceable in New Hampshire.

‍

In the Matter of Nizhnikov, 168 N.H. 525 (2016)‍

NH Supreme Court reversed the trial court and enforced a prenup signed the wedding day by a Russian wife who received the translated draft 11 days before an unscheduled marriage, distinguishing Hollett because the parties had comparable education and bargaining power (wife held a Russian law degree and managed the husband's 200-employee company) and the financial-disclosure waiver was knowing.

‍

In the Matter of Goddard, No. 2019-0735 (N.H. Nov. 2, 2020)‍

NH Supreme Court (Rule 20(3) order) affirmed enforcement of a prenup despite the wife's contributions of real-estate proceeds toward improvements on the husband's marital residence, holding that asset/income disparity alone does not render an agreement unconscionable, and affirmed the trial court's $250/month, four-year alimony award as consistent with the agreement's terms.

‍

In the Matter of Cicale, No. 2024-0370 (N.H. July 3, 2025)

‍NH Supreme Court (Rule 20(3) order) affirmed pretrial enforcement of a postnup awarding the wife (primary caregiver of two minor daughters) the marital home with all related expenses while splitting other assets equally, rejecting the husband's duress and unfairness challenges and confirming that postnup enforceability can be decided before the final divorce hearing.

1. Are prenuptial agreements enforceable in New Hampshire?

Yes. New Hampshire has authorized prenups since 1981 under RSA 460:2-a. A prenuptial agreement is presumed valid unless the party challenging it proves one of three grounds established in In the Matter of Yannalfo (2002) and In re Estate of Hollett (2003): (1) fraud, duress, mistake, misrepresentation, or nondisclosure of a material fact; (2) unconscionability; or (3) facts and circumstances so changed since signing that enforcement is now unconscionable. NH has not adopted the UPAA or UPMAA — enforcement is governed entirely by RSA 460:2-a plus case law from MacFarlane (1989) through Cicale (2025). Recent decisions in Nizhnikov (2016), Goddard (2020), and Cicale (2025) have all enforced prenups and postnups, making well-drafted agreements with full disclosure, independent counsel, and adequate lead time reliably enforceable.

‍

2. What invalidates a prenup in New Hampshire?

The most common grounds: (1) duress — a last-minute presentation combined with bargaining-power disparity, as in Hollett, where the court invalidated an agreement signed the wedding morning by a wife with minimal assets after only two days' notice; (2) inadequate or fraudulent financial disclosure; (3) lack of effective independent counsel for the disadvantaged party; (4) unconscionability at signing — terms so one-sided that no reasonable person would agree; or (5) changed circumstances making enforcement unconscionable at divorce, such as a spouse becoming destitute or eligible for public assistance. The challenging spouse bears the burden of proof on all five grounds. Yannalfo (2002) upheld a prenup signed a day before the wedding by postal-service spouses of comparable means — context matters more than timing alone.

‍

3. What is New Hampshire's "second look" doctrine, and why does it matter?

Most UPAA states review a prenup only at the time of signing. New Hampshire reviews it twice — at execution and at enforcement. Under MacFarlane v. Rich (1989), courts may refuse to enforce, or reform, provisions where changed circumstances make enforcement an "unconscionable hardship" at divorce. This means a prenup that was perfectly fair when signed can still be set aside years later if, for example, a serious illness, job loss, or other unforeseen event has fundamentally altered one spouse's circumstances. To reduce this risk, draft formula-based or capped provisions rather than absolute waivers, include periodic reaffirmation clauses, and attach updated financial disclosures throughout the marriage.

‍

4. How much does a prenup cost in New Hampshire?

Attorney-drafted prenups in NH typically run $3,000–$10,000 per couple ($1,500–$5,000 per side), with complex high-asset agreements reaching $15,000+. Hourly rates for NH family-law attorneys generally fall between $250 and $500. Online platforms with attorney review run roughly $600–$2,000 per couple but may not address NH-specific doctrines like the second-look test or Hollett's heightened procedural-fairness standard. The cost of not having a prenup can be far higher: without one, NH courts can divide all property — including premarital assets, inheritances, and business interests — under the 50/50 equitable presumption of RSA 458:16-a.

‍

5. Do both parties need their own attorney for a New Hampshire prenup?

Effectively yes. While RSA 460:2-a does not explicitly require independent counsel, NH case law treats it as a near-requirement where any disparity in education, assets, or sophistication exists. Hollett (2003) invalidated an agreement partly because the lower-asset spouse's attorney was a recent law-school graduate with no prenup experience, retained the day before the wedding. Both parties should retain separate counsel experienced in NH family law, early enough to verify financials and negotiate meaningful changes. If one party proceeds without an attorney, include a signed waiver-of-counsel provision — but understand that a court applying Hollett's "high standard of procedural fairness" may view the absence of effective counsel as a factor weighing against enforcement.

‍

6. How far before the wedding should a prenup be signed in New Hampshire?

There is no statutory minimum, but Hollett (2003) cites a 30-day pre-wedding presentation norm drawn from leading treatises as the floor to avoid involuntariness claims. We recommend signing 60+ days before the wedding for typical cases and 90+ days where there is significant asset or income disparity, with both parties having 2–3 weeks to review the final version. Start working with an attorney 4–6 months out. Hollett invalidated an agreement presented less than two days before a 200-guest wedding; Yannalfo (2002) upheld one signed a day before because the parties had comparable means and a narrow, easily understood agreement. The more complex or one-sided the prenup, the more lead time courts will expect.

‍

7. Does a New Hampshire prenup need to be notarized or witnessed?

RSA 460:2-a does not specifically require notarization or witnesses, but both are universal practice in NH and strongly recommended for evidentiary purposes. Notarization provides a verified record that each party personally appeared, showed identification, and signed voluntarily. NH practitioners typically have both parties' signatures notarized, with attorneys serving as witnesses at the signing. Skipping notarization creates an unnecessary evidentiary risk — if one party later claims they never signed, or signed under duress, a notary's certification is powerful rebuttal evidence.

‍

8. Why are prenups especially important in New Hampshire compared to other states?

New Hampshire is one of a small number of states that takes an "all property" approach to divorce. Under RSA 458:16-a, courts can divide any asset owned by either spouse — premarital savings, inheritances, gifts, family trusts, retirement accounts — regardless of when or how it was acquired. Most equitable-distribution states automatically protect "separate property" from division; NH does not. Without a prenup, the burden falls on each spouse to persuade the court why certain assets should be excluded. A prenup shifts that default: it designates specific property as separate, pre-allocates appreciation and income, and gives courts an enforceable framework under RSA 458:16-a, II(k), which lists prenup allocations as a statutory factor in property division.

‍

9. Can a New Hampshire prenup protect an inheritance, trust, or family wealth?

Yes — this is one of the strongest and most common uses. A prenup can designate expected inheritances, family trust distributions, and premarital assets as separate property, and can specify how appreciation and income from those assets will be treated during the marriage. This is especially important in NH because, without a prenup, inherited and gifted assets are subject to division under the all-property framework of RSA 458:16-a. Factor (n) of that statute considers "the value of any property acquired by gift, devise, or descent," but it is only one factor among 15 — not a guarantee of protection. A prenup converts a discretionary factor into a contractual obligation.

‍

10. Can a New Hampshire prenup protect a business or professional practice?

Yes. A prenup can classify a business interest — whether a sole proprietorship, LLC, partnership, or professional practice — as separate property and pre-define how to handle appreciation, goodwill, and income generated during the marriage. Without a prenup, NH courts can treat business value as divisible marital property, potentially forcing a sale, buyout, or valuation dispute at divorce. Best practice: include a valuation methodology (e.g., agreed-upon appraiser, multiple of revenue, book value) and specify whether active appreciation during the marriage is separate or marital. This avoids the most expensive and contentious part of a business-owner divorce — the valuation fight.

‍

11. Can a New Hampshire prenup waive alimony or spousal support?

Yes, but with meaningful risk. Alimony waivers are permitted, but under MacFarlane v. Rich (1989), NH courts may refuse to enforce — or reform — a waiver at divorce if enforcement would cause "unconscionable hardship" from changed circumstances. A waiver that leaves a spouse destitute or eligible for public assistance is highly vulnerable. NH also has a specific alimony guideline under RSA 458:19-a: 23% of the difference between the parties' gross incomes, for a maximum duration of 50% of the length of the marriage. Capped or formula-based alimony provisions that account for marriage duration and income changes are far safer than absolute waivers. If you include a waiver, add fallback language — e.g., a minimum monthly payment that prevents a destitution challenge.

‍

12. Can a New Hampshire prenup decide child custody or child support?

No. RSA 460:2-a explicitly prohibits any prenup term that "attempts to abrogate the statutory or common law rights of minor children of the contemplated marriage." Custody and child-support clauses are unenforceable, and including them risks undermining the credibility of the entire agreement. NH courts determine custody and support at divorce based on the children's best interests and the child-support guidelines in effect at that time. Do not include these provisions.

‍

13. Are postnuptial agreements legal and enforceable in New Hampshire?

Yes, since 2013. In re Estate of Wilber (165 N.H. 246) was the first NH case to formally enforce a postnuptial agreement, and In the Matter of Cicale (2025) reaffirmed enforcement and confirmed that postnup enforceability can be resolved before the final divorce hearing. Postnups are subject to at least the same three-prong scrutiny as prenups — fraud/duress/nondisclosure, unconscionability, and changed circumstances — and arguably a higher fairness standard given the existing fiduciary relationship between spouses. Wilber enforced a postnup between spouses married roughly 50 years despite no financial disclosures and no attorneys, because the challenging party failed to meet the burden of proof. That said, best practice is full disclosure, independent counsel, and adequate time — just as with a prenup.

‍

14. Does a prenup signed in another state hold up in New Hampshire?

Yes, generally. RSA 460:2-a expressly provides that NH courts "shall give the same effect to such contracts entered in other jurisdictions as would the courts of that other jurisdiction." A prenup valid under, say, Massachusetts or California law will typically be honored — subject to NH public-policy limits. Most importantly, child-support waivers remain unenforceable in NH regardless of where the prenup was signed, and NH courts retain the power to review for unconscionability at enforcement under the second-look doctrine. If you signed a prenup in a UPAA state and later divorce in NH, the agreement may face scrutiny it would not have faced in the originating state. Couples relocating to NH should have an NH attorney review the existing agreement for enforceability under NH case law.
