What is a New Jersey prenup?
Everything to know about New Jersey prenups.
Prenuptial agreements (or "antenuptial agreements" as they're called in New Jersey) are contracts entered into before marriage between a couple. They outline things like property ownership, property division, alimony, taxes, pets, rings, and many other topics. Prenups can be emotional documents as much as they are practical ones. They help set expectations and boundaries for a couple prior to entering into marriage, which in turn can create a stronger foundation for the marriage.
Prenuptial agreements in New Jersey are governed by the Uniform Premarital and Pre-Civil Union Agreement Act, N.J.S.A. 37:2-31 through 37:2-41, along with the relevant state case law that helps shape the laws around prenups. Below, everything you need to know, organized exactly the way a New Jersey family law attorney would walk you through it.
The controlling statute & cases
What law governs prenups in New Jersey?
New Jersey prenuptial agreements are governed by the Uniform Premarital and Pre-Civil Union Agreement Act, codified at N.J.S.A. 37:2-31 through 37:2-41. This statute sets out the formalities a prenup must meet, what it can include, and the specific grounds a court can use to throw out the agreement. After the New Jersey legislature adopted the Uniform Premarital Agreement Act in 1988, Hawxhurst v. Hawxhurst became a significant case interpreting the new statutory framework. The case upheld a prenuptial agreement where the husband's attorney drafted the agreement after consultations, the parties fully disclosed their assets and liabilities, and the agreement was the husband's own idea to protect his children's interests (Hawxhurst v. Hawxhurst, 318 N.J. Super. 72 (1998)).
Is New Jersey a UPAA state?
Yes, New Jersey has adopted its own version of the Uniform Premarital Agreement Act, expanded to also cover civil unions. The Legislature significantly amended the Act in 2013, adding more detailed enforcement standards than the original uniform model included, particularly around financial disclosure and access to legal counsel. So while New Jersey's law shares the same basic UPAA framework, its enforcement provisions are more layered than a bare-bones UPAA adoption.
Requirements for a New Jersey prenup
What are the requirements for a prenup in New Jersey?
Under N.J.S.A. 37:2-33, a premarital agreement in New Jersey must be in writing and signed by both parties, there must be a statement of assets attached to the agreement, and it is enforceable without any separate consideration. Beyond these basic formalities, New Jersey's enforcement statute, N.J.S.A. 37:2-38, sets a fairly detailed bar: the agreement must have been signed voluntarily, each party must have received full and fair disclosure of the other's income, property, and financial obligations (or knowingly waived that disclosure in writing), and each party must have either had the opportunity to consult independent legal counsel or knowingly and voluntarily waived that opportunity in writing. New Jersey does not require notarization or witnesses, and it doesn't set a fixed number of days that must pass between finishing the agreement and the wedding.
Requirements:
- In writing
- Signed by both parties
- Statement of assets attached
- Signed voluntarily
- Full and fair financial disclosure (or written waiver)
- Opportunity to consult independent counsel (or written waiver)
Does a prenup need to be notarized in New Jersey?
No, the Act doesn't require notarization for a prenuptial agreement to be valid. It's still a sensible extra step, often recommended by New Jersey prenup attorneys, since a notary's acknowledgment helps establish who actually signed the document and when, which can matter if the agreement is challenged later.
Do both parties need a lawyer for a prenup in New Jersey?
No, but each party needs to have had the opportunity to get one, which usually refers to the amount of time each party had after being presented with the agreement and their relative resources to do so. Under N.J.S.A. 37:2-38, a New Jersey prenuptial agreement is not enforceable if the party against whom enforcement is sought did not have the opportunity to consult with independent legal counsel and did not knowingly and voluntarily waive that opportunity in writing. A couple can technically proceed without both parties actually hiring an attorney, but the waiver of that opportunity has to be clear, informed, and in writing, or the agreement is exposed to a later challenge.
What makes a prenup invalid in New Jersey?
Under N.J.S.A. 37:2-38, a New Jersey court can decline to enforce a premarital agreement if the challenging party proves any of several things: that they didn't sign voluntarily; that the agreement was unconscionable; that they weren't given full and fair disclosure of the other party's income, property, and financial obligations and didn't waive that disclosure in writing; or that they weren't given the opportunity to consult independent counsel and didn't knowingly waive that opportunity in writing. An agreement that was never reduced to writing or signed by both parties also fails to meet the basic formalities under N.J.S.A. 37:2-33.
How long before the wedding should I sign a prenup in New Jersey?
New Jersey's statute doesn't specify a minimum number of days between finalizing the agreement and the ceremony. Even without a fixed rule, signing with real lead time matters, because a rushed, last-minute signing can support an argument that the agreement wasn't entered into voluntarily or that one party didn't have a genuine chance to review the terms or the "opportunity" to consult counsel, both of which go directly to enforceability under N.J.S.A. 37:2-38. For example, the most prominent New Jersey case involving timing of a prenuptial agreement signing is DeLorean v. DeLorean, where the wife signed the antenuptial agreement only a few hours before the marriage ceremony was performed, and the husband allegedly threatened to cancel the marriage if she did not sign. Despite these circumstances, the court upheld the agreement as valid, finding that the wife had signed voluntarily after privately consulting with an attorney who had actually advised her not to sign. The court's analysis focused on whether the wife had access to independent legal counsel and whether her decision to sign was ultimately her own, not on the mere hours between signing and the ceremony (DeLorean v. DeLorean, 211 N.J. Super. 432 (1986)).

Does cheating void a prenup in New Jersey?
No, not on its own. New Jersey allows couples to divorce on the no-fault ground of irreconcilable differences, but it also retains traditional fault grounds, including adultery (N.J.S.A. 2A:34-2). Even so, the New Jersey Supreme Court has held that marital fault generally isn't relevant to related financial issues like alimony, except in narrow situations, where the fault affected the couple's economic status, or where the misconduct was so egregious that ignoring it would offend basic notions of decency (Mani v. Mani, 183 N.J. 70 (2005)). Against that backdrop, a prenup clause imposing a flat financial penalty for infidelity is still at real risk of being challenged as unconscionable, since it functions as exactly the kind of fault-based financial punishment New Jersey courts have generally tried to avoid outside those narrow exceptions.
Are infidelity clauses enforceable in New Jersey?
They're on shaky ground. According to New Jersey-licensed attorney, Daniel Kokhba, "New Jersey is a no-fault divorce state, so infidelity clauses in prenuptial agreements are generally unenforceable. That said, some couples still include them to set expectations for the marriage and serve as a deterrent, even if a court is unlikely to enforce the provision."
Can a prenup include child custody in New Jersey?
No. Custody in New Jersey is determined according to the best-interest-of-the-child factors laid out in N.J.S.A. 9:2-4, and that determination has to reflect the child's actual circumstances at the time custody is at issue. A premarital agreement signed before a couple even has children cannot lock in custody arrangements years in advance. The analysis is meant to be done at the time of the custody dispute to ensure that the terms still make sense for the current-day situation.
Can a prenup protect a business in New Jersey?
Yes. N.J.S.A. 37:2-34 allows engaged couples to contract with respect to the rights and obligations of each party in property, including property acquired in the future, which covers business ownership interests. A New Jersey prenup can specify that a business owned before the marriage or created during the marriage, along with its future growth or any eventual buyout proceeds, remains separate property belonging to the business-owning spouse rather than becoming part of the marital estate subject to equitable distribution.
Can a prenup protect inheritance in New Jersey?
Yes. New Jersey's equitable distribution statute already treats property acquired by one spouse through gift or inheritance from a third party as exempt from distribution, but that exemption can weaken if the inherited assets are commingled with marital funds or if the other spouse contributes to their growth. A prenuptial agreement lets a couple spell out clearly, in advance, that inherited or gifted property, and any appreciation on it, will remain separate throughout the marriage.
Marital property in New Jersey
Is New Jersey a community property state?
No, New Jersey is an equitable distribution state. Rather than presuming that everything acquired during the marriage is automatically split 50/50, a New Jersey court divides marital property according to what it determines is fair given the specific facts of the marriage, which can be an equal split but doesn't have to be.
How is property divided in a divorce in New Jersey without a prenup?
New Jersey courts divide property under N.J.S.A. 2A:34-23.1, weighing a list of statutory factors, including the length of the marriage, each spouse's contributions (financial and otherwise) to the marital estate, the standard of living during the marriage, and each spouse's economic circumstances at the time the division takes effect. Assets acquired during the marriage are generally subject to equitable distribution regardless of whose name they're held in (Painter v. Painter, 65 N.J. 196 (1974)). Property owned before the marriage, or received by one spouse individually through gift or inheritance, is typically treated as separate and excluded from that division.
Does a prenup override equitable distribution in New Jersey?
Yes, a valid and enforceable prenuptial agreement can reshape how property would otherwise be divided under New Jersey's equitable distribution framework. Because N.J.S.A. 37:2-34 lets couples define their own property rights, a couple can specify in advance which assets are separate, how future acquisitions will be characterized, and how anything built together will be divided, effectively replacing the court's default discretionary analysis with terms the couple chose themselves, so long as the agreement holds up under N.J.S.A. 37:2-38.
What is separate property in New Jersey?
New Jersey doesn't use a single tidy statutory label the way some states do, but its equitable distribution law and case law consistently treat property owned before the marriage, along with gifts and inheritances received by one spouse individually, as separate property that isn't subject to division. That protection can erode if the property is commingled with marital assets or if the other spouse contributes meaningfully to its growth or upkeep, which is one reason a premarital agreement is often used to reinforce and clearly define what stays separate.
Spousal support in New Jersey
Can a prenup waive spousal support in New Jersey?
Yes. N.J.S.A. 37:2-34 specifically allows couples to contract for the modification or elimination of spousal support. As with other provisions in a New Jersey prenup, a support waiver still has to satisfy the enforcement standard under N.J.S.A. 37:2-38, meaning both parties need to have received adequate financial disclosure and had a genuine opportunity to consult independent counsel (or knowingly waived that opportunity in writing) before the waiver will be enforced.
Does a prenup prevent spousal support in New Jersey?
It can, if the agreement is written to do so and it satisfies New Jersey's enforcement standard. Since spousal support can be modified or eliminated by agreement under N.J.S.A. 37:2-34, a properly drafted and disclosed waiver gives a New Jersey court a strong basis to deny a later support claim. Because unconscionability and disclosure remain live issues under N.J.S.A. 37:2-38, a support waiver that was fairly negotiated with full financial transparency is far more durable than one that wasn't.
How is alimony determined in New Jersey without a prenup?
Without a prenup stating otherwise, New Jersey courts award alimony under N.J.S.A. 2A:34-23. Depending on the length of the marriage and the circumstances, a court may award open durational alimony, limited duration alimony, rehabilitative alimony, or reimbursement alimony, guided by factors such as:
- The actual need of one spouse and the other spouse's ability to pay
- The duration of the marriage
- Each spouse's age and physical and emotional health
- The standard of living established during the marriage
- Each spouse's earning capacities, education, and employability
- Parental responsibilities for the children
- The equitable distribution of property and any income it will generate
- The tax treatment of the alimony award
How much does a prenup cost in New Jersey?
How much does a prenup cost in New Jersey?
According to New Jersey prenup attorney, Daniel Kokhba, "For an attorney-drafted prenuptial agreement in New Jersey, couples can generally expect to pay $7,500 or more. Costs can scale much higher depending on the complexity of their assets and how much negotiation is involved." Costs vary based on the complexity of a couple's finances and which attorneys are involved. New Jersey couples with business interests, significant real estate holdings, or more involved negotiation between the parties should expect costs on the higher end of that range or beyond it.
What is the cheapest way to get a prenup in New Jersey?
The most cost-effective approach is generally to build the agreement through an online prenup platform and then have a New Jersey-licensed attorney review the completed draft at a flat rate, rather than paying an attorney hourly to draft the entire document. Platforms like HelloPrenup let couples complete a guided questionnaire to generate the agreement and then connect with licensed New Jersey attorneys for the review, disclosure discussion, and counsel documentation that New Jersey's enforcement statute expects.
How much does a prenup lawyer cost in New Jersey?
On average, New Jersey attorneys charge $363 per hour. Family law attorneys handling prenuptial agreements in New Jersey typically charge somewhere around that average, between $350 and $500 per hour or more, with rates in and around the New York City metro corridor often running toward the higher end. A simple agreement with modest, easily categorized assets generally takes fewer billable hours than one involving business interests, trusts, or extended negotiation between each side's attorney.

How do I get a prenup in New Jersey?
Couples in New Jersey generally take one of two paths: (1) each partner hires a separate attorney, with one drafting the agreement and the other reviewing and negotiating changes, or (2) the couple uses an online prenup platform to build the agreement and then brings in New Jersey attorneys for review and to document each party's access to counsel. Given New Jersey's specific requirements under N.J.S.A. 37:2-38, waiving your right to an attorney or involving an attorney at some point in the process is especially important.
Can I write my own prenup in New Jersey?
Technically, yes, but New Jersey's enforcement standard makes this a riskier path than in some other states. Because N.J.S.A. 37:2-38 requires that each party either had the opportunity to consult independent counsel or knowingly and voluntarily waived that opportunity in writing, a fully self-drafted agreement with no attorney involvement at all is more exposed to a later challenge on exactly that ground, in addition to the usual risks around unclear language or incomplete disclosure.
How long does it take to get a prenup in New Jersey?
Most couples should expect the process to take anywhere from a few weeks to a couple of months. Full financial disclosure is a central piece of New Jersey's enforcement standard, so gathering account statements, property records, and debt information properly the first time is worth the extra effort. If either party plans to consult an attorney, scheduling time with counsel for review and discussion can add to the overall timeline as well. With HelloPrenup, New Jersey couples can get a prenup same-day, sometimes within hours or a few days, depending on how committed they are to the process.
Do I need a lawyer to get a prenup in New Jersey?
You don't strictly have to hire one, but you do need to have had the opportunity to consult independent counsel, or have knowingly and voluntarily waived that opportunity in writing, for the agreement to be enforceable under N.J.S.A. 37:2-38. New Jersey courts have consistently applied this framework. In Dobre v. Dobre, the Appellate Division invalidated a prenuptial agreement specifically because the record lacked any convincing evidence that the defendant had consulted with independent counsel or that he had voluntarily and expressly waived, in writing, the opportunity to consult with independent legal counsel. The court's reasoning makes clear that the written waiver is a permissible substitute for actual representation, and the agreement failed not because counsel was absent, but because no written waiver existed (Dobre v. Dobre, App. Div. 2018).
Caselaw & enforceability
Are prenups enforceable in New Jersey?
Yes, prenuptial agreements are enforceable in New Jersey as long as they satisfy the requirements of N.J.S.A. 37:2-33 and 37:2-38. A party trying to avoid enforcement of a New Jersey prenup carries the burden of proving involuntariness, unconscionability, inadequate financial disclosure, or a lack of opportunity to consult independent counsel without a valid written waiver.
How hard is it to break a prenup in New Jersey?
It's difficult, but New Jersey's statute gives challengers more specific grounds to work with when attempting to "break" a prenup. Beyond arguing involuntariness or unconscionability, a spouse can also argue that they weren't given full and fair financial disclosure, or that they weren't given a real opportunity to consult independent counsel and never validly waived that opportunity in writing. Because New Jersey's enforcement statute lists these grounds explicitly, disputes tend to focus closely on exactly what disclosure was made and what each party understood about their right to counsel at the time of signing.
Can a judge throw out a prenup in New Jersey?
Yes, but only on one of the specific grounds set out in N.J.S.A. 37:2-38, not simply because the outcome seems lopsided years later. A judge will look closely at whether both parties had full and fair financial disclosure, whether each had a genuine opportunity to consult independent counsel, and whether the agreement was unconscionable. New Jersey courts, informed by decisions like Pacelli v. Pacelli, 319 N.J. Super. 185 (App. Div. 1999), tend to take a close, fact-specific look at these questions rather than treating a signed agreement as automatically final.
What can void a prenup in New Jersey?
A New Jersey premarital agreement can be found unenforceable if:
- It was not in writing or not signed by both parties
- It was not entered into voluntarily
- It was unconscionable
- One party was not given full and fair disclosure of the other's income, property, or financial obligations, and didn't waive that disclosure in writing
- One party did not have the opportunity to consult independent legal counsel and didn't knowingly waive that opportunity in writing
- A provision violates public policy or requires an illegal act
Outside of these grounds, New Jersey courts generally hold couples to the terms of their agreement.

Start your prenup for freeDuration & after-marriage
How long does a prenup last in New Jersey?
A valid New Jersey premarital agreement remains in effect for the duration of the marriage unless the couple builds in an end date. Some couples include what is called a "sunset clause" which effectively ends some or all of the agreement's terms after a set number of years or on a specific anniversary, such as on the 20th wedding anniversary, often to reflect that a long marriage has grown far more financially intertwined than it was at the start.
Can you get a prenup after marriage in New Jersey?
No, a prenuptial agreement has to be signed before the marriage or civil union by definition. Couples who are already married and want a similar arrangement typically look at a mid-marriage or postnuptial agreement instead. New Jersey courts generally hold these agreements to close scrutiny, often applying disclosure and fairness principles similar to those used for premarital agreements, given that spouses already owe each other a higher degree of trust and fair dealing once married than two people who are merely engaged. In addition, postnups in New Jersey must show that there was a true breakdown in the marriage that led to the negotiation of the agreement.
Can you change a prenup in New Jersey?
Yes. Under N.J.S.A. 37:2-37, a New Jersey prenup agreement may be amended or revoked only by a written agreement signed by both spouses, and no separate consideration is required for the amendment to be enforceable. Couples may want or need to get a prenup amendment due to a significant change in circumstances, such as starting a business that is not addressed in the original agreement, an unexpected large inheritance, or a significant change in lifestyle, such as one party staying home with the children.
Cross-border & recognition
Is a prenup signed in another state valid in New Jersey?
Under N.J.S.A. 37:2-34, New Jersey law allows couples to include a choice of law provision in their premarital agreement, specifying that another state's law will govern how the agreement is interpreted. A New Jersey court asked to enforce an out-of-state prenup will still evaluate whether the agreement meets New Jersey's own enforcement standards, particularly its disclosure and counsel requirements under N.J.S.A. 37:2-38, and whether enforcing a specific provision would conflict with New Jersey public policy, even where the agreement designates another state's law.
What happens to my New Jersey prenup if I move to another state?
This depends on how the new state treats choice-of-law provisions and its own premarital agreement law. Many states will generally respect a New Jersey choice-of-law clause and apply New Jersey's standards to interpret the agreement's terms, particularly for couples with a meaningful connection to New Jersey when they signed. Other states may still apply their own public policy limits to specific provisions, even while otherwise deferring to the parties' choice of law. For couples who live in New Jersey now but may relocate later, a clearly drafted choice-of-law clause improves the odds that New Jersey law will continue to govern the agreement, though it isn't a guarantee in every jurisdiction.
