Everything engaged couples need to know about making a prenuptial agreement valid and enforceable in New Hampshire — in plain English, reviewed by attorney James Sexton, Esq.
Yes — prenuptial agreements are legal and enforceable in New Hampshire under RSA 460:2-a and the case-law standards built on it.
RSA 460:2-a authorizes two people in contemplation of marriage to enter a written interspousal contract, and it bars any term that would abrogate the statutory or common-law rights of the couple's minor children. New Hampshire never adopted the Uniform Premarital Agreement Act, so the enforceability test comes from the New Hampshire Supreme Court — most prominently In re Estate of Hollett, 150 N.H. 39 (2003), which set aside a prenup signed under last-minute pressure with hastily arranged counsel. A properly made agreement is presumed valid; the burden of proving otherwise falls on the spouse attacking it.
A New Hampshire prenup is presumed valid and fails only if the challenger proves fraud, duress, mistake, misrepresentation or nondisclosure of a material fact, unconscionability, or such changed circumstances that enforcement would be unfair.
RSA 460:2-a requires a written contract made in contemplation of marriage, signed by both parties. Oral prenups are not enforceable.
Hollett is the cautionary tale: an agreement first presented days before the wedding, with counsel arranged at the last minute, was held involuntary. Sign well in advance — the court has suggested roughly 30 days as the safe zone.
Nondisclosure or misrepresentation of a material fact — hiding an asset, understating income — is an independent ground to void the agreement. Exchange complete written financial disclosures.
Uniquely, New Hampshire courts can also refuse enforcement if the parties' circumstances have changed so dramatically since signing that holding them to the deal would be unfair. Reasonable, two-sided terms age far better than one-sided ones.
| Governing statute | RSA 460:2-a — with standards from In re Estate of Hollett, 150 N.H. 39 (2003) |
|---|---|
| Property division | Equitable distribution |
| Notarization | Recommended (not required by statute) |
| Waiting period | None required — but sign well before the wedding |
| Spousal support | Alimony can be set or waived if the agreement is fair and fully disclosed |

New Hampshire courts set prenups aside for fraud, duress, nondisclosure of a material fact, unconscionability, or — uniquely — changed circumstances that make enforcement unfair.
The presumption of validity does real work in New Hampshire: the spouse challenging the agreement carries the burden. But the Hollett decision shows how quickly a prenup collapses when the process was rushed — there, a wealthy husband's agreement was voided because his fiancée got it days before the wedding with no meaningful chance to negotiate. And because New Hampshire recognizes the changed-circumstances ground, an agreement should be drafted to stay fair over a long marriage, not just on the wedding day. Early signing, full disclosure, and balanced terms are the whole game.

No — RSA 460:2-a requires only a written contract; notarization is not mandated by statute. It is still recommended as proof of authenticity and is available as an add-on.
Yes — on grounds of fraud, duress, mistake, misrepresentation or nondisclosure of a material fact, unconscionability, or dramatically changed circumstances since signing. The challenger bears the burden, so a fairly made, fully disclosed agreement is presumed valid.
In re Estate of Hollett, 150 N.H. 39 (2003), is New Hampshire's leading prenup decision: the Supreme Court voided an agreement presented to the bride days before the wedding with last-minute counsel. It's the reason every New Hampshire prenup should be finalized and signed well in advance.
It's possible — New Hampshire is one of the few states where a court can decline to enforce a prenup if circumstances have changed so much since signing that enforcement would be unfair. Drafting terms that stay reasonable over time is the best protection.
Yes, alimony can be set or waived in a New Hampshire prenup, provided the agreement was fairly made with full disclosure and isn't unconscionable when the court examines it.
Yes — New Hampshire enforces properly executed prenuptial agreements regardless of how they were drafted. What matters is execution: a written agreement, voluntary signatures, full financial disclosure, and New Hampshire's signing formalities. The full picture is in are online prenups legally binding.
