Prenuptial Agreement Requirements in Vermont

At a glance

Requirements one by one

Vermont uses a Statute of Frauds plus case law

Vermont has no comprehensive Uniform Premarital Agreement Act. The writing rule comes from 12 V.S.A. § 181, and the Vermont Supreme Court's Lacroix v. Rysz, 2025 VT 16, supplies the current statement of the enforceability framework first developed in Bassler v. Bassler.

The ordinary divorce statutes remain the backdrop. 15 V.S.A. § 751(a) gives the court equitable-property authority, and § 752(a)-(b) supplies the maintenance framework unless an enforceable agreement changes the parties' rights.

The charged party must sign a writing

Section 181 bars an action on an agreement made in consideration of civil marriage unless the agreement, or a memorandum or note of it, is in writing and signed by the party to be charged. Enforcement against both spouses therefore normally calls for both signatures, but the statute itself is phrased in terms of the person against whom enforcement is sought.

Marriage supplies the contemplated consideration. No separate payment or exchange is required merely to support the premarital bargain.

No special notary or witness formality applies

Section 181 requires a writing and the charged party's signature. Vermont has not added a prenup-specific notary, acknowledgment, witness, oath, attestation, or recording requirement for basic enforcement between spouses.

A deed or another instrument used to carry out a real-property provision may have its own formalities. That does not convert those rules into universal prenup execution requirements.

Fair financial disclosure is an affirmative requirement

Lacroix restates the first Bassler factor: each spouse must make fair and reasonable disclosure of financial status. Vermont's controlling case-law test does not replace disclosure with the UPAA alternatives of an express written waiver or actual or constructive adequate knowledge.

Disclosure is assessed with the rest of the formation process, but it remains a separate enforceability requirement rather than merely evidence bearing on unconscionability.

Counsel and signing time are assessed through voluntariness

Vermont has no fixed statutory counsel mandate or pre-wedding review period. The second Lacroix/Bassler factor asks whether each spouse entered the agreement voluntarily and freely.

In Lacroix, the signer received the proposed agreement about two weeks before the wedding, retained independent counsel, negotiated terms, received full disclosure, and signed one day before the ceremony against counsel's advice. The trial court's finding of voluntary execution was not disputed on appeal. That fact pattern is not a one-day safe harbor; it illustrates Vermont's case-specific approach.

Lacroix separates fairness from unconscionability

The fairness source is case law. Lacroix identifies four requirements: fair financial disclosure, voluntary execution, substantively fair property terms, and an agreement that was not unconscionable when made. It treats substantive fairness and unconscionability as distinct inquiries.

Unconscionability is measured at execution. Lacroix rejected the proposition that leaving each spouse in the premarriage financial position automatically “vitiates” marriage or makes the agreement unconscionable.

Maintenance may be waived, subject to public-charge policy

A prenup may eliminate maintenance. Lacroix reversed a ruling that treated the lack of a significant property award or maintenance as inherently unconscionable and explained that preserving premarital assets is a central purpose of these agreements.

The divorce-time limit is narrower. Bassler, reaffirmed in Lacroix, bars enforcement when the agreement would leave a spouse a public charge or close to it. Vermont does not use a general enforcement-time unconscionability review to rebalance every harsh support waiver.

Child support and parental rights remain with the court

Section 654 requires a child-support guideline and makes the calculated amount the presumptive total parental obligation. 15 V.S.A. § 665(a)-(b) requires the court to order parental rights and responsibilities and directs it to the child's best interests.

Those statutory duties prevent a premarital agreement from conclusively fixing child support or binding the court's parental-rights decision.

Later modification follows ordinary contract rules

Vermont has no prenup-specific amendment or revocation statute. In Gamache v. Smurro, the Supreme Court stated that the parties remained free to modify the agreement whether or not it contained a modification clause. A later deed and the parties' conduct superseded the inconsistent earlier property term.

The route therefore depends on ordinary contract law and the subject of the change, not a universal notarized-amendment formality.

What trips people up

• Fairness and unconscionability are separate. Lacroix treats them as two distinct requirements and measures unconscionability at execution.
• One day before the wedding is not a statutory deadline. The full circumstances in Lacroix supported voluntariness; Vermont has no one-day safe harbor.
• The public-charge test is not a general second look. It protects the public and the dependent spouse without authorizing a complete rewrite based only on later inequality.

Common questions

Does a Vermont prenup need notarization?

The governing Statute of Frauds requires a writing signed by the party charged. It does not require notarization or witnesses for the prenup itself.

Can a maintenance waiver be enforced?

Yes, if the agreement otherwise satisfies Lacroix and Bassler. But public policy prevents enforcement that would leave the spouse a public charge or close to it at divorce.

Must both prospective spouses have lawyers?

No statute or controlling case makes actual separate counsel a universal condition. Counsel, negotiation, timing, disclosure, and understanding can be important evidence of voluntary and fair execution.
