In 2026, a prenup typically costs between $600 and $10,000 or more per couple, depending on how the agreement is created.
A DIY online template runs about $600, software-drafted agreements with attorney review run $2,000 and up, and a traditional attorney billing hourly typically costs $2,500 to $10,000 or more.
At Prenups.com, a prenup is a flat $3,500. No hourly billing.
| 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 Connecticut’s enforceability rules is a fundamentally different product from an online template. A $3,500 agreement that holds up in court is worth more than a $600 template that does not.
Key Takeaways
- In 2026, a prenup in Connecticut typically costs between $600 and $10,000 or more per couple, depending on how it is created. Prenups.com charges a flat $3,500, with no hourly billing.
- Under Conn. Gen. Stat. § 46b-36g, a Connecticut prenup can be challenged on four independent grounds: it was not voluntary, it was unconscionable, disclosure was inadequate, or a spouse had no reasonable opportunity to consult counsel.
- Connecticut has a built-in second look. Unconscionability can be tested at signing or at enforcement, which is unusual among states that follow the uniform act.
- Witnesses are not required, but the reasonable opportunity to consult counsel is its own ground, so independent review for your partner is worth planning for.
- Connecticut’s 2023 divorce rate was 2.6 per 1,000 residents, according to CDC/NCHS. Most couples never test their agreement, and for those who do, it is judged against four grounds and a second look.
What a Prenup Costs in Connecticut
A prenup in Connecticut typically runs between $2,500 and $10,000 when an attorney bills hourly. The low end usually means a simple agreement between two people with uncomplicated finances, and at the very bottom of that range you are often paying for a near-form document from an attorney who does not specialize in these agreements. Add a business, significant premarital assets, children from a prior relationship, or heavy negotiation, and the number climbs toward the top of the range.
Put the price in context. Connecticut’s 2023 divorce rate was 2.6 per 1,000 residents, according to CDC/NCHS data, so most couples will never put their agreement to the test. For the couples who do, the agreement is measured against a standard that gives a challenger more room than most states do. That is what you are paying to prepare for.

What You Are Opting Out Of
Without an agreement, a Connecticut court divides property under equitable distribution, meaning the judge decides what is fair, which is not always the same as equal. Connecticut is an all-property state, so the court’s reach is not limited to what you acquired during the marriage. Assets you owned before the wedding can be part of the conversation.
A prenup replaces that open question with terms you chose. In Connecticut it also has to be built to withstand a statute with several ways to attack it.
Four Grounds, Each Enough on Its Own
Connecticut’s Premarital Agreement Act, Conn. Gen. Stat. §§ 46b-36a to 46b-36j, lists the grounds on which an agreement can be set aside, and they are independent of each other. Under § 46b-36g, a challenger can succeed by showing the agreement was not signed voluntarily, that it was unconscionable, that disclosure was inadequate, or that a spouse did not have a reasonable opportunity to consult independent counsel. The burden sits on the challenger, and witnesses are not required.
The structure matters because the grounds are not paired. In states that follow the standard uniform test, a challenger has to show unconscionability and inadequate disclosure together. In Connecticut, each ground can stand by itself. An agreement with perfect disclosure can still be challenged as unconscionable, and an agreement with fair terms can still be challenged because a spouse never had a reasonable chance to consult a lawyer.
The Built-In Second Look
Connecticut also tests unconscionability at two points in time. The agreement can be reviewed at signing or at enforcement, and Crews v. Crews, 295 Conn. 581 (2010), confirmed that terms are tested at enforcement as well as at execution. Most states that follow the uniform act judge an agreement only as of the day it was signed.
Here, the substance of the terms keeps mattering for years. An agreement that looked balanced when both spouses had similar careers can be examined again after one has stepped back from work, and a court can ask whether enforcing it now would be unconscionable.
Thinking about a prenup?
Talk to an attorney before you decide. A 30-minute consultation is $150, credited toward your agreement if you move forward.
Schedule a Consultation →What the Four Grounds Mean for Drafting
A careful Connecticut agreement is built to answer all four grounds, not just the one a challenger is likely to choose. Voluntariness means enough time and no ultimatum around the signing. Disclosure means full, current information about assets, debts, and income. The counsel ground means each spouse has a real, documented opportunity to consult their own attorney before signing. And the second look means the terms have to stay reasonable over time.
“Connecticut gives a challenger four separate ways to attack a prenup, and the unconscionability test can be run at signing or at enforcement, so the agreement has to be built to answer all four, for the long haul,” says Aaron Thomas, Esq., founder of Prenups.com.
No agreement can promise how a particular court will rule, and anyone who says otherwise is overselling. A prenup that is enforceable in court in Connecticut closes each door as far as it can: voluntary signing, complete disclosure, documented access to counsel, and terms that stay balanced.
What Moves the Price
Complexity does most of the work. Two people early in their careers with straightforward assets need a simpler agreement than a couple bringing a business, real estate, retirement accounts, or equity compensation into the marriage. Couples are also marrying later. The U.S. Census Bureau reports a 2025 median age at first marriage of 30.8 for men and 28.4 for women, so many people arrive with years of financial history already built.
Negotiation is the second lever, since an aligned couple moves quickly and a couple working out support or a business spends more time. Independent review for your partner is the third. Connecticut does not require a lawyer for each spouse, but because the opportunity to consult counsel is its own ground for challenge, it is the piece of the process that answers a whole category of attack.
Why a Fixed Price Fits a Statute With Four Doors
Most Connecticut family law attorneys bill prenups by the hour. That is hard to budget for, because the final bill depends on how many revisions you want and how long a negotiation runs, none of which you can know on day one. It also creates a quiet temptation to trim the steps that answer the four grounds when the meter feels high.
Prenups.com charges $3,500 for a Connecticut prenup, with no hourly billing, so the price is known before the work begins. An attorney is also in the conversation from the first call, before anything is drafted, which is where disclosure, review time, and the counsel opportunity get built in.
Starting the Process
The process begins with a consultation to understand your situation and goals, followed by financial disclosure from both people, drafting, a round of review and revisions with a documented chance for each spouse to consult counsel, and signing. Connecticut does not require witnesses, so signing is straightforward once the agreement is ready. For the full picture of what the flat fee covers, see the flat-fee pricing.

Frequently Asked Questions
How much does a prenup cost in Connecticut?
In 2026, a prenup typically costs between $600 and $10,000 or more per couple, depending on how it is created. A traditional attorney billing hourly usually runs $2,500 to $10,000 or more. At Prenups.com, a Connecticut prenup is a flat $3,500, with no hourly billing.
What are the four grounds for challenging a Connecticut prenup?
Under Conn. Gen. Stat. § 46b-36g, a challenger can show the agreement was not voluntary, that it was unconscionable, that disclosure was inadequate, or that a spouse had no reasonable opportunity to consult independent counsel. Each ground is independent of the others.
Does Connecticut take a second look at a prenup at divorce?
Yes. Unconscionability can be tested at signing or at enforcement, and Crews v. Crews confirmed that terms are tested at enforcement as well as at execution. That is unusual among states that follow the uniform act.
Does a Connecticut prenup need witnesses or a lawyer for each partner?
Connecticut does not require witnesses. A reasonable opportunity to consult independent counsel is an independent ground for challenge, so it matters in practice. The $3,500 flat fee is for the agreement itself, and independent review for your partner is separate.
Is a $600 online template enough in Connecticut?
Rarely. A template does not build the disclosure record, the documented counsel opportunity, or terms designed to hold up over time, and it comes with no attorney to do so. A flat $3,500 agreement that holds up in court is worth more than a $600 template that does not.
Can we sign a postnup in Connecticut?
Yes. Under Bedrick v. Bedrick, postnuptial agreements are enforceable in Connecticut but must be fair and equitable when signed and not unconscionable at dissolution.
