Prenuptial Agreement in
Massachusetts

Massachusetts is notable because it has not adopted the UPAA or UPMAA — instead, Massachusetts courts evaluate prenuptial agreements under a long-standing common law standard developed through case law. Under the leading case of Rosenberg v. Lipnick, a prenuptial agreement is enforceable if it was fair and reasonable at the time of execution, the parties had reasonable financial disclosure, and it remains fair and reasonable at the time of enforcement. This two-stage fairness review makes careful drafting especially important in Massachusetts.

How Massachusetts handles marital property

Equitable Distribution

Massachusetts follows equitable distribution and is an "all property" state, meaning courts can consider all property in a divorce, not just marital property.

Legal framework

State-specific in Massachusetts

State-specific

Massachusetts has not adopted the UPAA or UPMAA. Prenup enforceability is governed by case law, particularly the DeMatteo v. DeMatteo standard. The agreement must be fair and reasonable at the time of execution and not be unconscionable at the time of divorce.

Massachusetts applies a "second look" doctrine: the prenup must be fair both when signed and at the time of divorce. This is more protective than many other states. Full financial disclosure and independent counsel are strongly recommended.

Requirements

What makes a prenup valid in Massachusetts

Understanding these requirements helps ensure your agreement will hold up when it matters most.

Notarization

Notarization is strongly recommended. While not always strictly required, it significantly strengthens enforceability.

Witnesses

Witnesses are strongly recommended to establish voluntariness.

Timing

No specific statutory timing requirement. Courts consider whether both parties had adequate time and opportunity to review the agreement and consult counsel.

Spousal Support

Spousal support waivers are enforceable but subject to a "second look" at the time of divorce. Courts may refuse to enforce a waiver if it would be unconscionable given changed circumstances.

The Law

What Massachusetts law actually says

Massachusetts antenuptial agreement statute and common law

Mass. Gen. Laws ch. 209, § 25; DeMatteo v. DeMatteo, 436 Mass. 18 (2002)

  • The agreement must be in writing and signed by both parties before the marriage.
  • Each party must fairly disclose their assets, income, and liabilities — attaching financial schedules is standard practice.
  • Both parties must sign voluntarily, with time to consider the terms; the opportunity to consult a lawyer strengthens the agreement but is not mandatory.
  • The agreement must be fair and reasonable at signing and conscionable when enforced.
  • Notarization and witnesses are not required by statute, though notarizing is commonly done.

How Massachusetts courts treat prenups

Massachusetts applies the well-known "two-look" test from DeMatteo v. DeMatteo (2002). First look: was the agreement fair and reasonable when signed? The SJC set a forgiving bar — an agreement is valid unless it essentially strips the contesting spouse of substantially all marital interests, and full disclosure plus voluntary signing carry most of the weight. Second look: at divorce, the judge asks whether enforcement is conscionable now, given how circumstances actually unfolded during the marriage — an agreement that would leave a spouse unable to support themselves can be set aside even if it was fine at signing. This second look makes Massachusetts one of the more protective states at enforcement time.

Coverage

What your Massachusetts prenup can address

A prenuptial agreement in Massachusetts can cover a wide range of financial and property matters.

Protection of pre-marital real estate throughout Massachusetts and on Cape Cod or the Islands
Separation of business interests in professional practices, technology ventures, and financial services firms
Spousal support provisions, including amount, duration, and modification conditions
Treatment of retirement accounts, investment portfolios, and pension benefits accumulated before marriage
Allocation of pre-marital student loan debt, particularly common given Massachusetts' large graduate-school population
Rights to intellectual property, patents, and licensing royalties developed before or during the marriage
Financial rights if one spouse pauses a career to raise children, including compensation provisions

Best practices

Tips for a strong prenup in Massachusetts

Following these best practices helps ensure your agreement is clear, fair, and enforceable.

Massachusetts uses a unique two-stage fairness test — at signing and at enforcement — so avoid extremely one-sided terms that could look unreasonable if circumstances change over time.

Provide complete financial disclosure in writing; Massachusetts courts look closely at whether both parties had enough information to make an informed decision.

Execute the agreement several weeks before the wedding so the timing cannot be used to suggest duress or insufficient review time.

Both spouses should retain independent Massachusetts-licensed attorneys, as independent legal counsel is particularly significant evidence of voluntariness under Massachusetts case law.

Consider including provisions for how career sacrifices — such as one spouse reducing work hours for childcare — will be acknowledged financially, since Massachusetts courts factor these contributions into their fairness analysis.

Cost

How much does a prenup cost in Massachusetts?

The cost of a prenuptial agreement in Massachusetts varies depending on how you create it and the complexity of your financial situation.

Traditional attorney

$2,500–$10,000+

Per spouse. Involves multiple consultations, document drafting, negotiation rounds, and review. Each party typically needs their own attorney, so total costs can reach $5,000–$20,000+ for the couple.

Process

How to get a prenup in Massachusetts

Follow these steps to create an enforceable prenuptial agreement that meets Massachusetts's legal requirements.

1

Start the conversation early

Bring up the topic of a prenup with your partner well before the wedding — ideally at least 2–3 months ahead. No specific statutory timing requirement. Courts consider whether both parties had adequate time and opportunity to review the agreement and consult counsel. Starting early shows both parties entered the agreement without pressure.

2

Gather your financial information

Both partners should prepare a complete picture of their finances: assets, debts, income, and any expected inheritances. Massachusetts requires full financial disclosure for a prenup to be enforceable.

3

Draft the agreement

Create your prenuptial agreement using prenups.ai's guided questionnaire, which is specifically tailored to Massachusetts's equitable distribution system and State-specific requirements. The AI drafts a comprehensive, jurisdiction-aware document in minutes.

4

Review with independent attorneys

Witnesses are strongly recommended to establish voluntariness. While Massachusetts may not strictly require each party to have their own attorney, independent legal review significantly strengthens enforceability and ensures both spouses understand the terms.

5

Sign and execute properly

Notarization is strongly recommended. While not always strictly required, it significantly strengthens enforceability. Both parties must sign the agreement voluntarily. Keep the original in a safe place and provide copies to both spouses and their attorneys.

FAQ

Common questions about prenups in Massachusetts

What legal standard applies to prenuptial agreements in Massachusetts?

Massachusetts does not follow the UPAA or UPMAA. Instead, courts apply a common law standard requiring that the agreement was fair and reasonable at execution, that both parties had adequate financial disclosure, and that it remains fair and reasonable at the time of enforcement.

What is the two-stage fairness test in Massachusetts?

Under Massachusetts case law, a prenup must pass a fairness review both at the time it was signed and at the time it is enforced. This means a court can decline to enforce provisions that were reasonable when signed but have become inequitable due to unforeseen changes in circumstances.

Does Massachusetts require independent legal counsel for a prenup?

Massachusetts does not mandate independent counsel by statute, but courts give significant weight to whether both parties had their own attorneys when evaluating voluntariness. Independent representation is strongly recommended.

Can a Massachusetts prenup waive alimony?

Yes, but Massachusetts courts will scrutinize such waivers closely under both stages of the fairness test. If enforcing a spousal support waiver would leave one spouse in severe financial hardship, a court may decline to enforce it.

Can a prenup be thrown out in Massachusetts?

Yes, under either prong of the two-look test. A Massachusetts prenup can fail at the "first look" if it wasn't fair and reasonable when signed — typically because of missing financial disclosure, duress, or terms stripping one spouse of virtually everything. It can also fail at the "second look" if enforcing it at divorce would be unconscionable, for example leaving a spouse without means of self-support after a long marriage. Well-disclosed, voluntarily signed agreements with non-extreme terms routinely survive both looks.

How do I get a prenup in Massachusetts?

Start early — months before the wedding, not days. Exchange complete financial disclosures (assets, debts, income), decide together how you want property, appreciation, and support handled, and put the terms in a written agreement both of you sign before the ceremony. You can create the document yourselves or online; notarizing the signatures is a sensible extra step. Each of you having an independent attorney review it is optional, but it strengthens the agreement against later challenge.

How much does a prenup cost in Massachusetts?

Massachusetts is among the pricier states for attorney-drafted prenups: Boston-area family lawyers commonly quote $3,000 to $8,000, and negotiated agreements involving businesses, trusts, or significant premarital wealth can exceed $10,000 across both parties' counsel. Building the agreement online for a flat $349 — with full financial schedules attached — and then optionally hiring a local attorney for an hourly review gives couples a DeMatteo-conscious document without the four-figure drafting bill.

How long does it take to get a prenup in Massachusetts?

With prenups.ai, you can have a draft prenuptial agreement in under 20 minutes. Traditional attorney routes in Massachusetts typically take 2–6 weeks due to scheduling, drafting, negotiation, and review. No specific statutory timing requirement. Courts consider whether both parties had adequate time and opportunity to review the agreement and consult counsel. We recommend starting the process at least 2–3 months before your wedding to allow time for review and any revisions.

Can I create a prenup without a lawyer in Massachusetts?

Yes. Massachusetts does not require you to have an attorney to create a valid prenuptial agreement. However, having each party consult with independent legal counsel significantly strengthens enforceability. Many couples use prenups.ai to create the initial draft and then have it reviewed by attorneys, which is much more affordable than starting from scratch.

What happens if I don't get a prenup in Massachusetts?

Without a prenup, Massachusetts's default equitable distribution rules apply. Massachusetts follows equitable distribution and is an "all property" state, meaning courts can consider all property in a divorce, not just marital property. A prenup lets you define your own terms instead of leaving these decisions to state law or a judge's discretion.
