A prenup typically costs between $600 and $10,000 or more per couple, depending on how the agreement is created.
A do-it-yourself online template runs about $600, but carries real enforceability risk. Pairing an online template with attorney review generally costs $2,000 and up. A traditional attorney billing hourly typically runs $2,500 to $10,000 or more, depending on complexity and negotiation.
A flat-fee, attorney-drafted prenup costs $3,500 at Prenups.com, with no hourly billing and no surprises.
| Approach | Typical cost (per couple) | When a lawyer gets involved | Best for |
|---|---|---|---|
| DIY online template | $600 | Never | Simple finances, no major assets, willing to risk enforceability |
| Software-drafted + attorney review | $2,000 and up | After the document is generated | Couples who have already agreed on every term and want it documented |
| Attorney-drafted, flat fee (Prenups.com) | $3,500 flat, plus independent review for your partner | From the first conversation, before anything is drafted | Couples who want an attorney to design the agreement around their goals, at a predictable price |
| Traditional hourly attorney | $2,500 to $10,000+ | From the first conversation | Couples with an existing attorney relationship, open-ended budget |
A prenup drafted by a licensed attorney who knows New Jersey’s specific formalities is a fundamentally different product from an online template. A $3,500 agreement that holds up in court is worth more than a $600 agreement that does not.
New Jersey Locked In Pro-Enforcement Rules in 2013, But Added Two Formalities That Trip Up Templates
New Jersey changed its own law in 2013 in a way that matters more than most legislative amendments do. Before then, an agreement could be revisited years later if circumstances changed enough to make it unfair by the time of divorce. The 2013 amendment eliminated that second look entirely: New Jersey now judges an agreement’s fairness only as of the day it was signed, which makes the state notably pro-enforcement once an agreement clears that one moment in time.
That same law added two specific formalities a generic template is unlikely to get right. A statement of both spouses’ assets has to be physically annexed, attached, to the agreement itself, not just referenced or filed separately. And if one spouse goes unrepresented, that spouse needs a written waiver acknowledging they had the opportunity to consult their own attorney and chose not to. Skip either one and you’ve handed a future challenger exactly the kind of technical defect New Jersey’s otherwise pro-enforcement standard doesn’t protect you from.
Key Takeaways
- A prenup in New Jersey generally costs between $2,500 and $10,000 with hourly billing, or a flat $3,500 through Prenups.com, once you move past a bare-bones DIY template.
- New Jersey’s 2013 amendment locked fairness review to the date of signing, eliminating the second-look review some other states still apply at divorce, which makes New Jersey genuinely pro-enforcement once an agreement is properly executed.
- Two formalities are unique to New Jersey and easy for a generic template to miss: a statement of assets must be physically annexed to the agreement, and an unrepresented spouse needs a written waiver of their opportunity to consult counsel.
- A challenger has to prove unconscionability at signing by clear and convincing evidence, a demanding standard that favors whichever spouse is relying on the agreement.
- The real comparison is not template versus attorney. It is the cost of a solid, correctly formatted agreement now versus a technical defect that undoes an otherwise strong agreement later.
What Determines the Price
A handful of factors move a New Jersey prenup up or down the cost scale. The complexity of your finances is the biggest driver: two people early in their careers with straightforward assets need a simpler agreement than a couple bringing a business, real estate, or significant premarital assets into the marriage.
Whether one spouse consults independent counsel matters specifically in New Jersey, since an unrepresented spouse needs a documented written waiver rather than just going without a lawyer informally. Handling that correctly takes a small amount of extra drafting care that a generic template typically skips entirely.
The amount of negotiation is the final variable. A couple aligned on the terms moves quickly. A couple negotiating spousal support or how a business is treated will spend more time, and under hourly billing, more time means more money.
Hourly Billing vs. Flat-Fee Pricing
Most New Jersey family law attorneys bill by the hour, which means your final cost depends on variables you can’t predict at the outset: how many rounds of revision, how long negotiation runs, how much time goes into getting the formalities right. The number you hear on day one rarely matches the invoice at the end.

Schedule a Consultation →Prenups.com drafts New Jersey prenups on a flat fee of $3,500, covering the full process from the first consultation through final signing, including handling the annexed asset statement and any required counsel waiver correctly the first time, with no hourly charges and no surprise add-ons.
Is a Prenup in New Jersey Worth the Cost?
New Jersey’s standard is clearly favorable to a properly executed agreement. Because the 2013 amendment locked review to the date of signing, a couple doesn’t have to worry about a court reopening the substance of their agreement years later based on how circumstances changed. A challenger has to show the agreement was unconscionable at signing, by clear and convincing evidence, which is a high bar.
That favorable standard only protects you if the execution itself was done right. An agreement missing the annexed asset statement or the written counsel waiver hands a challenger a technical argument that has nothing to do with whether the terms themselves were fair. Set against the cost of a contested divorce fought over exactly that kind of defect, the fee for a correctly executed agreement is not really a cost. It’s the price of making sure New Jersey’s pro-enforcement standard actually works in your favor.

Frequently Asked Questions
How much does a prenup cost in New Jersey?
A New Jersey prenup typically costs between $2,500 and $10,000 with hourly billing, depending on complexity and negotiation. Prenups.com offers a flat-fee New Jersey prenup for $3,500.
What changed with New Jersey’s 2013 prenup law?
The 2013 amendment locked an agreement’s fairness review to the date it was signed, removing the second look some states apply years later at divorce. This makes New Jersey notably pro-enforcement once an agreement is properly executed.
What is the “annexed statement of assets” New Jersey requires?
It’s a document listing both spouses’ assets that must be physically attached to the prenup itself, not just referenced or kept in a separate file. Missing this formality is a technical defect a challenger can raise regardless of whether the agreement’s terms were otherwise fair.
Do both spouses need a lawyer for a New Jersey prenup?
Not strictly, but if one spouse goes without independent counsel, that spouse needs to sign a written waiver acknowledging they had the opportunity to consult an attorney and chose not to. Skipping that documentation creates the same kind of technical vulnerability as missing the asset statement.
How hard is it to challenge a prenup in New Jersey?
Harder than in many states. A challenger has to prove the agreement was unconscionable at the time of signing, using clear and convincing evidence, and cannot rely on how circumstances changed later since New Jersey eliminated that second look in 2013.
Is a cheap online prenup template a good deal in New Jersey?
Rarely, and New Jersey is a state where the gap shows up in a very specific way. A generic template is unlikely to include the annexed asset statement or a properly worded counsel waiver, and either omission can undo an agreement regardless of how fair its actual terms are.
