Connecticut Prenuptial Agreement
Connecticut prenuptial agreements are governed by the Connecticut Premarital Agreement Act (C.G.S. § 46b-36a et seq.). Courts apply dual review — unconscionability is assessed at both signing and divorce, meaning more judicial review. Independent counsel is not required, though both parties must have the opportunity to retain it.
Bottom line: Connecticut earns a C grade. Dual review creates enforcement uncertainty. Execute cleanly and disclose fully — including income, not just assets. A prenup is still far better than none.

Connecticut Prenup Laws: Key Statutes Explained
Connecticut Premarital Agreement Act (1995)
Separate Property
All assets can remain separate property, avoiding costly divorce settlements. Joint assets and debts titled in both names are split 50/50 as marital property.
Unconscionability Dual Review
Connecticut reviews prenuptial agreements for unconscionability both at execution (signing) AND at enforcement (divorce), meaning courts can easily reject or modify agreements if circumstances change during marriage. This creates uncertainty regarding entering into prenuptial agreements and marriage.
Unconscionability Standard
A prenup is unenforceable if the challenging party proves: (1) involuntary execution; (2) unconscionability at signing OR enforcement; (3) inadequate financial disclosure; OR (4) no opportunity for independent counsel. Connecticut requires "an extremely high level of unfairness"—provisions that "surprise or shock the conscience."
Spousal Support Public Assistance Minimum
Maintenance waivers can be reviewed for unconscionability at both execution and enforcement. Courts may override spousal support waivers if enforcement would make one party eligible for public assistance, and if circumstances change during marriage, courts can require significantly more than public assistance.
Timing
No minimum specified, but we recommend signing the prenup 60+ days before the wedding, with both parties having 2-3 weeks to review the final version to minimize challenge risk. Reach out to an attorney at least 4-6 months before the wedding with your draft prenup. Better yet, sign the prenup before proposing.
Independent Counsel
Not required, but separate counsel dramatically strengthens enforceability if the agreement is later challenged. Both parties must at least have the opportunity to retain counsel.
Financial Disclosure
"Fair and reasonable" disclosure of all property interests required. Disclose all assets $1,000+ and income. A prenup disclosing approximate property holdings but insufficient income information was held unenforceable.
Medium Burden to Challenge
Challenging party bears the burden of proof by preponderance of evidence (standard burden, not higher clear and convincing threshold). Connecticut's dual-review unconscionability test and multiple enforcement grounds make prenups easier to modify or reject than stricter states.
Child Support and Custody
Child support and custody clauses are unenforceable and could undermine the entire agreement. Do not include.
Connecticut Prenuptial Agreement Court Cases
Peterson v. Sykes-Peterson, 133 Conn. App. 199 (2011)
Prenup with sunset provision expiring on seventh wedding anniversary was unenforceable where husband filed for divorce four months before anniversary but parties were still married on the anniversary date, as court found the unambiguous contract language voided the agreement based solely on reaching the anniversary while married, regardless of pending divorce proceedings.
Grabe v. Hokin, 341 Conn. 360 (2021) (Partially Modified)
Supreme Court enforced prenup where wife had $27.4 million and husband's assets dropped from $5 million to $2.1 million after house fire, yacht club destruction, and business failures, finding changed circumstances insufficient for unconscionability, but struck down the attorney fees provision requiring husband to pay over $1.5 million as unconscionable since it would financially cripple him.
Friezo v. Friezo, 281 Conn. 166 (2007)
Supreme Court enforced prenup limiting wife to $400,000 plus residence where draft was provided one week before wedding and she consulted attorney for 30 minutes three days before wedding, holding that "fair and reasonable disclosure" focuses on substance not timing, and "reasonable opportunity" for counsel means opportunity for consultation, not extensive review.
Crews v. Crews, 295 Conn. 153 (2010)
Supreme Court reversed the Appellate Court and enforced pre-1995 prenup despite 15+ year marriage with two children and substantial contributions by wife, holding that equitable considerations have no bearing on enforcement and courts cannot rewrite agreements based on changed circumstances unless they rise to unconscionability.
Winchester v. McCue, 91 Conn. App. 721 (2005)
Appellate Court enforced prenup after 15-year marriage despite husband's assets increasing approximately 430% during marriage, finding that even including husband's $200,000 pension, the disparity in parties' financial situations remained substantially the same at execution and enforcement.
Beyor v. Beyor, 165 Conn. App. 193 (2015)
Appellate Court enforced prenup where husband had $4.5 million net worth and wife had $26,000 at divorce, holding agreement not unconscionable where wife voluntarily married husband with full understanding that if marriage failed she would receive nothing, despite her having ceased working and husband's substantially greater financial means.
5-Step Checklist: How to Sign & Execute a Prenup in Connecticut
Step 1: Download and read the Connecticut prenuptial agreement
Start with our free template. It is written for Connecticut-specific statutes and case law under the Connecticut Premarital Agreement Act (C.G.S. § 46b-36a et seq.). Read it in full — know what you are getting into legally with marriage. The 15+ pages is written thoroughly to include rebuttals to common legal challenges and fallback provisions.
Step 2: Draft changes on your own
See a clause you don't like? Copy it into an AI like Claude, explain what you'd like to change or what you want the clause "to do." Save any changes as a separate alternate version — don't overwrite the original. Bring both versions to your attorney review. Note: AI is often gender-biased and crafts terms beyond what is legally required. Push back on its output.
Step 3: Find a lawyer in your state
Find a matrimonial or divorce attorney in your state. Avvo, Findlaw, and Justia are good. Look for someone with 10+ years experience. Call or email and ask them how much to review your draft prenup and help with signing. Send them your draft.
Step 4: Meet your lawyer 4–6 months before the wedding
Our recommendation: sign the prenup before proposing. That way, you both get the legal work out of the way, and you know this is the right person to marry. Already proposed? 4–6 months before the wedding should leave you enough time to give your spouse 1–2 weeks to review the final draft and have it signed 60+ days before the wedding. Connecticut has no statutory minimum waiting period, but Friezo confirmed that adequate time to consult counsel is a legal requirement — presenting a prenup days before the wedding means it can easily be rejected by a court later.
Step 5: Sign, notarize, and store the agreement
Execute the agreement with both attorneys present — their witness signatures carry more enforceability weight than a standalone notary. Connecticut law requires only a writing signed by both parties (§ 46b-36c) — notarization is not mandated by statute, but it authenticates signatures and provides evidence of voluntariness, the most frequently litigated issue. Each party keeps a signed original, and so should each party's attorney. Store yours somewhere secure like a safety deposit box. Create a .pdf and save it via a backup drive and email.
Connecticut Prenuptial Agreement: Frequently Asked Questions (2026)
What is a prenuptial agreement?
A legal contract signed before marriage that determines how assets, debts, and finances are handled in the event of divorce, instead of state laws which the couple is unaware of and are often punitive. In our prenup, assets and debts are kept separate, unless held jointly, where they are split 50/50. Alimony is modified to incentivize larger families and longer marriages, rather than divorce. A privacy clause allows the growth of an intimate, trusting relationship. A dispute resolution clause moves proceedings out of a courtroom and into mediation or arbitration, preserving an ongoing relationship.
How much does a prenup cost in Connecticut?
Attorney-drafted from scratch: $1,500–$5,000+ per side. The smarter approach: start with our free Connecticut template, make changes with an AI like Claude, then hire an attorney only to review and assist with signing. The bill should be around $500 per side.
Are prenups enforceable in Connecticut?
Yes, but Connecticut earns a C rating. Courts review unconscionability at both signing and divorce, giving judges two opportunities to modify or reject provisions. The challenging party bears the burden of proof under four independent grounds: involuntary execution, unconscionability at signing or enforcement, inadequate financial disclosure, or no reasonable opportunity to consult counsel. Even though Connecticut doesn't have the strongest laws, prenup is still far better than no prenup.
What makes a prenup invalid in Connecticut?
Under C.G.S. § 46b-36g(a), any one of four grounds is enough: involuntary execution, unconscionability at signing or at divorce, failure to disclose the amount, character, and value of property, financial obligations, and income, or no reasonable opportunity to consult independent counsel. Crucially, income disclosure is a standalone requirement — one Connecticut appellate court invalidated a prenup that disclosed approximate asset holdings but failed to adequately disclose income (132 CA 609). Also, leave out sunset clauses: in Peterson, a prenup with a 7th-anniversary expiration date was voided because the anniversary arrived while the marriage was still technically intact, even though divorce was already pending. Leave child custody and support out entirely.
Do I need a lawyer to get a prenup in Connecticut?
Not technically — Connecticut requires only that each party have a reasonable opportunity to consult independent counsel, not that they actually retain one (§ 46b-36g(a)(4)). Friezo confirmed that a 30-minute consultation three days before the wedding, after having the draft for one week, satisfied this standard. That said, both sides having separate attorneys is by far the strongest protection against a voluntariness challenge and dramatically increases enforceability. Use the template to cut drafting costs — don't skip the attorney.
What should a Connecticut prenuptial agreement include?
Our Connecticut template is built around six core principles:
- Separate property — assets and debts stay with the party who acquired them, minimizing conflict
- Joint assets and debts — anything both parties sign for together is split 50/50
- Marital home — ownership is tracked as a percentage of contribution, so each party gets back what they put in
- Spousal support — structured to incentivize larger families and longer marriages, not divorce
- Full financial disclosure — all assets, debts, and income over $1,000, listed in the exhibits, satisfying C.G.S. § 46b-36g(a)(3)
- Privacy clause — keeps financial and personal details private, supporting a trusting relationship
Leave out child custody and support entirely — Connecticut courts will not enforce them and they can invalidate the rest of the agreement.
Why does Connecticut's property law make a prenup especially important?
Connecticut is an all-property equitable distribution state — one of the most aggressive property division regimes in the country. Without a prenup, a court can divide virtually everything both spouses own at divorce, including assets brought into the marriage, inheritances received during the marriage, and gifts. There is no statutory "separate property" protection. A judge decides what is "fair" using broad discretion, which produces unpredictable outcomes and expensive litigation. A prenup is the only reliable way to establish in advance which assets stay with each party.
How far in advance should I get a prenup in Connecticut?
Sign 60+ days before the wedding. Give your spouse at least two weeks to review with their own attorney — Connecticut courts require a "reasonable opportunity to consult counsel" and have upheld prenups where one week's notice and a brief attorney consultation were sufficient (Friezo), but closer to the wedding increases challenge risk. Contact an attorney 4–6 months before the wedding. Best practice: sign before proposing — no time pressure, and you'll ensure this is the person who is really after marriage, not divorce.
Can a prenup be challenged at the time of divorce in Connecticut?
Yes — this is Connecticut's most significant enforceability risk. Under C.G.S. § 46b-36g(a)(2), a prenup can be challenged as unconscionable at the time enforcement is sought, not just at signing. This means a court can revisit your agreement at divorce and strike provisions it finds grossly unfair given how circumstances changed during the marriage. In Grabe (2021), the Supreme Court upheld the core prenup despite the husband's substantial financial reversal — but struck the attorney fee provision as unconscionable.
