Everything engaged couples need to know about making a prenuptial agreement valid and enforceable in New Jersey — in plain English, reviewed by attorney James Sexton, Esq.
Yes — prenuptial agreements are legal and enforceable in New Jersey under the state's Uniform Premarital Agreement Act.
New Jersey adopted the Uniform Premarital Agreement Act in 1988, codified at N.J.S.A. 37:2-31 through 37:2-41. Under N.J.S.A. 37:2-33, the agreement must be in writing with a statement of assets annexed, signed by both parties, and it is enforceable without consideration. A 2013 amendment (L.2013, c.72) significantly strengthened enforceability: unconscionability is now measured only at the time of execution, so a prenup that was fair when signed can no longer be reopened at divorce just because life turned out differently.
A New Jersey prenup is enforceable unless the challenger proves, by clear and convincing evidence, that it was signed involuntarily or was unconscionable when executed — including for lack of disclosure or lack of independent counsel that wasn't waived in writing.
N.J.S.A. 37:2-33 requires more than a signature: a written statement of each party's assets must be attached to the agreement itself. A missing asset schedule is New Jersey's most avoidable drafting failure.
Both parties must sign free of duress or coercion. Present the agreement early — not during wedding week — so voluntariness is never in doubt.
Under N.J.S.A. 37:2-38, an agreement is unenforceable if the challenger wasn't given full and fair disclosure of the other party's earnings, property, and financial obligations — unless disclosure was voluntarily and expressly waived in writing.
New Jersey's enforceability analysis asks whether each party consulted independent counsel — or voluntarily waived that opportunity in writing. Getting the waiver (or the lawyer) documented is cheap insurance.

|---|---|
| Property division | Equitable distribution |
| Notarization | Recommended (not required by statute) |
| Waiting period | None required — but sign well before the wedding |
| Spousal support | Can be modified or waived if not unconscionable when signed |

New Jersey courts invalidate prenups only when the challenger proves, by clear and convincing evidence, involuntary signing or unconscionability at the time of execution — including inadequate disclosure or an unwaived lack of independent counsel.
The 2013 amendment to N.J.S.A. 37:2-32 and 37:2-38 moved New Jersey from one of the friendlier states for prenup challengers to one of the stricter ones: courts now look only at the circumstances when the agreement was signed. 'Unconscionable' is defined narrowly — an agreement that would leave a spouse without reasonable support or make them a public charge. The compliance checklist is concrete: annex both asset statements, exchange full disclosure, document independent counsel or its written waiver, and sign early. Do that, and a New Jersey prenup is among the most durable in the country.

No — N.J.S.A. 37:2-33 requires a signed writing with a statement of assets annexed, but not notarization. Notarizing is still recommended as proof of authenticity and is available as an add-on.
Yes, but the bar is high: under N.J.S.A. 37:2-38 the challenger must prove by clear and convincing evidence that the agreement was signed involuntarily or was unconscionable when executed. Since 2013, how things look at divorce is irrelevant to unconscionability.
N.J.S.A. 37:2-33 requires a written statement of each party's assets to be attached (annexed) to the prenup itself. It's a formality unique to a handful of states — and skipping it is one of the easiest ways to render a New Jersey prenup vulnerable.
L.2013, c.72 amended N.J.S.A. 37:2-32 and 37:2-38 so that unconscionability is judged only at the time the agreement was executed, not at enforcement. Before 2013, a spouse could attack a prenup because circumstances had changed by the time of divorce; now a fairly signed agreement stays enforceable.
Not strictly — but New Jersey's enforceability test asks whether each party consulted independent counsel or voluntarily waived that right in writing, so the choice must be documented. Trusted Prenup offers an optional attorney-review add-on for New Jersey couples.
Yes — New Jersey 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 Jersey's signing formalities. The full picture is in are online prenups legally binding.
