What to know:
- New Hampshire never adopted the Uniform Premarital Agreement Act; its prenup statute, RSA 460:2-a, is one sentence long, and the rest of the rules come from court decisions.
- A New Hampshire prenup is presumed valid, and the partner challenging it must prove fraud, duress, misrepresentation, nondisclosure, unconscionability, or a major change in circumstances, per In re Estate of Hollett, 150 N.H. 39 (2003).
- Without a prenup, RSA 458:16-a directs a New Hampshire court to presume that an equal division is the equitable one, across everything either partner owns, however and whenever acquired.
- Hiring two attorneys in New Hampshire commonly runs $1,600 to $9,900 for a couple, billed at published New Hampshire firm rates of $150 to $400 an hour.
- First offers a fully online way to create a valid, enforceable New Hampshire prenup for a flat fee, with online notarization included, so couples can handle disclosure and timing on their own schedule.
You are planning a wedding in New Hampshire, and somewhere between the venue deposits and the guest list, the question of a prenup came up. Maybe one of you owns a home in Manchester. Maybe there is a business, or student debt, or a family inheritance you would like to keep clear. Whatever prompted it, you want to know what New Hampshire law says before you decide anything.
Here is the reassuring part. New Hampshire recognizes prenups and presumes they are valid, which means the law starts on the side of the agreement two partners signed. Hiring two attorneys to draft one commonly runs $1,600 to $9,900 for a couple, based on published New Hampshire firm rates of $150 to $400 an hour. There is also a fully online path. This guide walks through what makes a New Hampshire prenup valid, how the state divides property when there is no agreement, what one costs, and how to get one.
Are prenups valid in New Hampshire?
Yes. New Hampshire recognizes prenuptial agreements, and the statute that governs them is short. New Hampshire never adopted the Uniform Premarital Agreement Act, the model law used in 29 states plus the District of Columbia. Instead, the state's prenup statute, RSA 460:2-a, is one sentence long. It confirms that a couple contemplating marriage may agree in writing on how property will be handled, with one limit we will get to below.
Because the statute says so little, most of what makes a New Hampshire prenup work comes from court decisions rather than the code itself. The most important of those is In re Estate of Hollett, a 2003 New Hampshire Supreme Court case that laid out how courts treat these agreements. The headline from Hollett is favorable to couples who plan ahead: a New Hampshire prenup is presumed valid, and the person trying to set it aside carries the burden of proving it should not stand.
What makes a New Hampshire prenup enforceable?
Because the agreement starts out presumed valid, the question a court asks is whether the partner challenging it can knock it down. In In re Estate of Hollett, the New Hampshire Supreme Court identified the grounds a challenger must prove: fraud, duress, mistake, misrepresentation, or nondisclosure of a material fact; that the agreement is unconscionable; or that circumstances have changed so much since signing that enforcing it would work an injustice.
Unconscionable is a legal standard for an agreement so one-sided or unfair that a court will refuse to enforce it. It is a high bar, and a court does not reach it lightly. Most of the grounds circle back to two things a couple controls directly: whether each partner told the truth about their finances, and whether each partner had a fair chance to understand what they were signing.
That second point is about timing. New Hampshire has held that signing a prenup close to the wedding is not, by itself, duress, a point drawn from In the Matter of Yannalfo (2002) and cited in Hollett. Even so, Hollett called the timing of the agreement of paramount importance in deciding whether it was signed voluntarily, and set aside an agreement presented less than 48 hours before the wedding. Full financial disclosure is the other lever, and it is worth understanding why full disclosure matters so much before you start. An agreement built on complete disclosure and signed with time to spare is built to pass the Hollett test. If you want the broader picture, our guide on what makes a prenup enforceable covers the principles that apply across states.
How does New Hampshire divide property without a prenup?
To understand what a prenup does for you, it helps to see the default it replaces. Without a prenup, New Hampshire courts follow RSA 458:16-a, which presumes that an equal division is an equitable distribution of property. New Hampshire is an equitable distribution state rather than a community property state, and "equitable" does not always mean "equal." The statute lets a court divide property differently when the circumstances call for it, but the starting presumption is a 50/50 split.
What surprises many couples is how broad that division reaches. RSA 458:16-a defines property to include everything either partner owns, however and whenever it was acquired. That means assets you brought into the marriage, gifts, inheritances, and property held in one partner's name alone can all be on the table. A prenup is the tool that lets you agree, in advance and in writing, on a different arrangement, so that the home you owned before the wedding or the business you built stays defined the way the two of you intend.
What can a New Hampshire prenup cover?
A New Hampshire prenup can address the financial picture the two of you are bringing into the marriage and how it will be handled going forward. That includes separate property each partner owned before the wedding, how assets and income acquired during the marriage will be treated, and how debts will be assigned. If one partner is carrying student loans or a business line of credit, the agreement can designate that debt as their responsibility rather than a shared obligation.
There is one clear limit in the statute. RSA 460:2-a prohibits a prenup from including any term that attempts to abrogate the statutory or common-law rights of minor children of the contemplated marriage. In plain terms, you cannot use a prenup to sign away a child's right to support. Child-related matters are decided by a court based on the child's best interests, whatever the agreement says. Everything on the property and debt side, though, is where a prenup does its work.
How much does a prenup cost in New Hampshire?
Cost is often what tips a couple from thinking about a prenup to deciding whether to get one, so here is a straight comparison of the two paths New Hampshire couples take.
The traditional route is two attorneys, one for each partner, because a single lawyer cannot represent both sides of the same agreement. Published New Hampshire family-law firm rates run $150 to $400 an hour, and once you account for both attorneys drafting, reviewing, and going back and forth, the total for a couple commonly lands between $1,600 and $9,900. The wide range reflects how much the complexity of your finances and the amount of negotiation drive the hours.
The online route is a flat fee. A prenup with First is $649 for the couple, with online notarization included. No hourly billing, no back and forth with attorneys, no PDFs to chase down. For a fuller picture of pricing across the market, our guide on how much a prenup costs breaks down the variables.
| Path | Typical cost for the couple | How it is billed | Notarization |
|---|---|---|---|
| Two independent attorneys | $1,600 to $9,900 | Hourly, $150 to $400 per hour, two attorneys | Arranged separately |
| First (online, flat fee) | $649 flat for the couple | One flat fee | Online notarization included |
Where in New Hampshire you live, whether that is Concord, Nashua, or a small town in the North Country, does not change the process or the price of the online path.
How do you get a prenup in New Hampshire?
Getting a prenup in New Hampshire comes down to a few steps, and the good news is that the most important ones are the ones you control.
Start with disclosure. Each partner lays out their finances in full: assets, income, debts, and anything of value. This matters because nondisclosure of a material fact is one of the grounds a challenger can raise under Hollett. Next comes the drafting itself, where you decide together how property, income, and debts will be handled and put it in writing.
Then think about timing. New Hampshire sets no statutory waiting period, and courts have strongly recommended signing well ahead of the wedding rather than in the final days before it. Signing months out removes the argument that anyone was rushed. Finally comes signing. New Hampshire does not require either partner to have an attorney, and it does not require notarization, for a prenup to be valid. What the law asks is that the agreement be in writing and signed freely by both partners, with full disclosure behind it. Notarizing it is still worth doing, because a notarized signature is straightforward evidence that both partners signed, and First includes online notarization at no extra cost. If you want to see how New Hampshire compares with other states, our state-by-state guide to how prenups vary puts it in context.
Frequently asked questions
Are prenups enforceable in New Hampshire?
Yes. New Hampshire presumes a prenuptial agreement is valid. The partner trying to undo it must prove fraud, duress, mistake, misrepresentation, or nondisclosure of a material fact; that the agreement is unconscionable; or that circumstances have changed so much it can no longer be enforced. An agreement built on full disclosure and signed with time to spare is built to pass that test.
Do both people need a lawyer for a prenup in New Hampshire?
No. New Hampshire does not require either partner to be represented for a prenup to be valid. What a court looks at is whether both people signed freely and knew what the other had. Disclosure and timing are within your control, and they matter more to a court than whether a lawyer was in the room.
Does a New Hampshire prenup have to be notarized?
No. New Hampshire does not require a prenup to be notarized for it to be valid. Notarizing it is still worth doing, because a notarized signature is straightforward evidence that both partners signed. First includes online notarization at no extra cost.
When should we sign a prenup in New Hampshire?
As early as you reasonably can. New Hampshire sets no waiting period, but how much time each partner had to read and consider the agreement matters if it is ever challenged. A late signing hands a partner who later challenges the agreement an argument. Signing months ahead removes the argument.
How much does a prenup cost in New Hampshire?
With First, a New Hampshire prenup is $649 flat for the couple, with online notarization included. Hiring attorneys instead commonly runs $1,600 to $9,900 for the couple, billed hourly at published New Hampshire rates of $150 to $400 an hour, because each partner retains their own attorney.
Can I do a New Hampshire prenup online?
Yes. Nothing in New Hampshire law treats an agreement differently because of how it was produced. What matters is that it is in writing and signed, that both partners disclosed their finances fully, and that both signed freely.
