A prenuptial agreement for a second marriage in Massachusetts costs $2,500 to $5,000 total for both spouses in 2026, requires compliance with the DeMatteo v. DeMatteo two-look test established in Mass. Gen. Laws ch. 209, § 25, and must be signed at least 30 days before the wedding to maximize enforceability. Massachusetts courts evaluate prenups at both the time of signing and at divorce, making proper drafting essential for protecting assets, children from previous marriages, and inheritance rights in blended families.

Why Second Marriages in Massachusetts Need Prenuptial Agreements
Second marriages in Massachusetts face a 58% divorce rate in the Northeast region, compared to approximately 40% for first marriages nationally, making prenuptial agreements critical financial planning tools for remarrying couples. Massachusetts law under Mass. Gen. Laws ch. 208, § 34 treats all property as divisible in divorce, including assets acquired before marriage, inheritances, and retirement accounts, meaning a spouse entering a second marriage without a prenup risks losing assets intended for children from a previous relationship. The DeMatteo v. DeMatteo framework established in 2002 provides a clear path to enforceable agreements when properly executed, but requires meeting requirements at both signing and enforcement.
Massachusetts is one of 22 states that has not adopted the Uniform Premarital Agreement Act (UPAA), instead relying on case law that gives judges significant discretion in evaluating prenuptial agreements. This judge-made law approach means Massachusetts courts can invalidate even properly signed prenups if enforcement would leave one spouse without sufficient property, maintenance, or appropriate employment to support themselves. For second marriages involving children from prior relationships, business interests, or significant pre-marital assets, this two-look framework makes professional legal drafting essential rather than optional.
Massachusetts Prenuptial Agreement Legal Requirements
A valid Massachusetts prenuptial agreement requires a written document signed by both parties, notarized signatures, full financial disclosure, and terms that are fair and reasonable at execution under Mass. Gen. Laws ch. 209, § 25. The statute permits couples to designate any property owned at the time of marriage as separate property that will remain with the original owner. Massachusetts courts have expanded these requirements through the DeMatteo two-look test, adding conscionability review at enforcement.
First Look Requirements (At Signing)
Massachusetts courts evaluate five elements when examining a prenup at the time of execution:
- Both parties signed voluntarily without duress, threats, or coercion
- Each party received full and fair financial disclosure of all assets, debts, income, and business interests
- The agreement is in writing with notarized signatures
- Terms are fair and reasonable, not stripping one party of substantially all marital interests
- Each party had opportunity to consult independent legal counsel
The financial disclosure requirement mandates listing all real estate, bank accounts, investments, personal property, debts, loans, credit cards, mortgages, income sources, and financial obligations. Failure to disclose the existence or value of a premarital asset is one of the most common reasons Massachusetts courts reject prenuptial agreements.
Second Look Requirements (At Divorce)
Massachusetts courts conduct a second evaluation when a divorcing spouse seeks to enforce a prenuptial agreement, applying a conscionability standard established in DeMatteo v. DeMatteo, 436 Mass. 18 (2002). A court may decline to enforce an otherwise valid prenup if enforcement would leave the contesting spouse without sufficient property, maintenance, or appropriate employment to support themselves.
Circumstances that can trigger second-look invalidation include:
- Deterioration of one spouse's mental or physical health during marriage
- Inflation negating the practical effect of fixed-dollar provisions
- Complete waiver of alimony leaving one spouse destitute after a long marriage
- Changed economic circumstances making original terms unconscionable
Importantly, valid agreements may be one-sided under Massachusetts law. A contesting party may have considerably fewer assets after divorce than during marriage. Courts only invalidate agreements when one party is essentially stripped of substantially all marital interests.
Protecting Children from Previous Marriage in a Prenup
A Massachusetts prenuptial agreement can designate specific assets as separate property intended for children from a prior relationship, preventing those assets from becoming divisible marital property under Mass. Gen. Laws ch. 208, § 34. Without this protection, Massachusetts courts can divide all property regardless of when or how it was acquired, potentially awarding a new spouse assets the remarrying parent intended for their biological children.
What a Prenup Can Protect for Your Children
Massachusetts prenups for second marriages commonly address:
- Real estate acquired before remarriage
- Retirement accounts and pension benefits
- Business ownership interests
- Investment and brokerage accounts
- Life insurance policy designations
- Inheritance rights and expected future inheritances
- Family heirlooms and collectibles
- College savings plans (529 accounts)
Massachusetts uniquely considers future inheritances in divorce proceedings through Vaughan affidavits, making prenuptial protection of expected family wealth particularly important for second marriages.
Combining Prenups with Estate Planning
A prenuptial agreement works alongside wills and trusts to protect children's inheritance. Massachusetts elective share laws allow a surviving spouse to claim a portion of the deceased spouse's estate regardless of the will. A prenup can include a waiver of elective share rights, ensuring assets pass to children as intended. The recommended approach combines:
- Prenuptial agreement designating specific assets as separate property
- Revocable trust holding assets for children's benefit
- Pour-over will directing remaining assets to the trust
- Beneficiary designations on retirement accounts and life insurance
The Commingling Risk
Inherited assets and separate property can lose their protected status if commingled with marital funds. Depositing inherited money into a joint bank account or using premarital assets to purchase a jointly owned home may convert separate property to marital property. A Massachusetts prenup should include provisions addressing how to handle inadvertent commingling and establishing procedures for tracing separate property.
Massachusetts Prenuptial Agreement Costs for Second Marriages
A prenuptial agreement for a second marriage in Massachusetts costs $2,500 to $5,000 total for both spouses with moderate asset complexity, based on attorney hourly rates ranging from $250 to $500 per hour in 2026. Boston-area family law specialists command rates at the higher end, while attorneys in Springfield, Worcester, and other cities outside Greater Boston charge $200 to $350 per hour.
| Complexity Level | Estimated Cost | Typical Situations |
|---|---|---|
| Simple | $1,500-$2,500 | Few assets, no business interests, no children |
| Moderate | $2,500-$5,000 | Second marriage, children from prior relationship, retirement accounts |
| Complex | $5,000-$10,000 | Business ownership, significant investments, multiple properties |
| High-net-worth | $10,000-$15,000+ | Business valuations required, trusts, international assets |
Business valuations add $3,000 to $10,000 to prenup costs when a Massachusetts business owner needs independent appraisal of company value. Flat-fee arrangements provide cost certainty: simple prenups typically run $1,500 to $2,500 as a flat fee per attorney.
Online prenup services like HelloPrenup offer Massachusetts-specific templates for $599 per couple, but these carry enforceability risks under the DeMatteo two-look test because no independent attorney reviews the terms with each spouse.
What Massachusetts Prenups Can and Cannot Include
Massachusetts prenuptial agreements under Mass. Gen. Laws ch. 209, § 25 can address property characterization, division provisions, and certain spousal support terms, but cannot override court authority over children or include unconscionable provisions.
Enforceable Prenup Provisions
- Designation of property as separate or marital
- Division of property in event of divorce
- Alimony/spousal support terms (subject to second-look review)
- Waiver of elective share inheritance rights
- Responsibility for premarital debts
- Treatment of income earned during marriage
- Distribution of appreciation on premarital assets
- Pet ownership arrangements
Unenforceable Prenup Provisions
Massachusetts courts will not enforce:
- Any limitation on child support obligations
- Custody or parenting time provisions (courts retain full authority)
- Lifestyle clauses penalizing weight gain, appearance changes, or infidelity
- Provisions violating public policy
- Terms requiring illegal conduct
- Unconscionable provisions leaving one spouse destitute
Alimony Waivers in Massachusetts Prenups
Massachusetts courts generally uphold alimony waivers in otherwise valid prenuptial agreements, but the second-look doctrine provides important protection. An absolute waiver of alimony that would leave one spouse unable to support themselves after a long marriage may be modified or invalidated at divorce. The emerging reality is that most probate and family court judges will only invalidate a prenuptial agreement if enforcement would leave a party in fairly extreme financial distress.
Timing and Process for Massachusetts Prenups
Massachusetts couples should begin the prenup process at least 3 to 6 months before the wedding date to ensure adequate time for negotiation, financial disclosure, and attorney review. While Massachusetts law does not specify a minimum timeframe, signing closer than one week before the wedding creates duress concerns that may invalidate the agreement.
Recommended Timeline
| Timeframe Before Wedding | Action Item |
|---|---|
| 6 months | Begin initial discussions with future spouse |
| 5 months | Each party retains independent attorney |
| 4 months | Exchange complete financial disclosures |
| 3 months | Draft agreement and begin negotiations |
| 2 months | Finalize terms and address concerns |
| 1 month | Sign and notarize final agreement |
| 30+ days | Buffer period before wedding |
Step-by-Step Process
- Initial consultation with family law attorney ($250-$500 for first meeting)
- Gather financial documents: tax returns, bank statements, property deeds, retirement account statements, business records
- Complete financial disclosure schedule listing all assets and debts
- Exchange disclosures with future spouse
- Negotiate terms through attorneys or directly
- Draft formal agreement with all required provisions
- Review final draft with respective attorneys
- Sign in presence of notary public
- Each party retains original signed copy
Massachusetts Property Division Without a Prenup
Massachusetts follows equitable distribution under Mass. Gen. Laws ch. 208, § 34, but uniquely makes all property divisible regardless of when or how it was acquired. Unlike most states that protect premarital assets, Massachusetts courts can divide property brought into the marriage, gifts received by one spouse, and even inheritances.
Factors Courts Consider
Massachusetts judges evaluate these factors when dividing property without a prenup:
- Length of the marriage
- Conduct of the parties during marriage
- Age, health, and occupation of each party
- Amount and sources of income
- Vocational skills and employability
- Estate, liabilities, and needs of each party
- Opportunity for future acquisition of capital assets and income
- Present and future needs of dependent children
- Contribution of each party to the acquisition of marital property
- Contribution as homemaker
There is no presumption of 50/50 division in Massachusetts. Courts have broad discretion to award any percentage deemed equitable based on the circumstances. Property division is final and not modifiable after divorce, unlike alimony or child support.
Special Considerations for Massachusetts Second Marriage Prenups
Blended Family Financial Planning
Second marriages involving children from both spouses' previous relationships require careful prenup provisions addressing:
- Which assets will fund each set of children's education
- How life insurance benefits will be allocated
- Whether the family home will pass to children or surviving spouse
- Retirement account beneficiary designations
- Treatment of child support received or paid to former spouses
Existing Alimony Obligations
If either party pays alimony to a former spouse, the prenup should address:
- How alimony payments affect available income
- What happens if the obligation terminates
- Whether new marriage income will be shielded from modification claims
Debt Protection
Second marriages often involve existing debt from prior divorces. A Massachusetts prenup can:
- Designate premarital debt as individual responsibility
- Protect one spouse from the other's student loans
- Address credit card debt carried into marriage
- Establish procedures for handling joint debt incurred during marriage
How to Challenge or Defend a Massachusetts Prenup
A Massachusetts prenuptial agreement may be challenged on procedural grounds (problems at signing) or substantive grounds (unconscionable at enforcement) under the DeMatteo two-look framework.
Common Grounds for Invalidation
- Lack of full financial disclosure
- Duress, coercion, or undue pressure to sign
- Insufficient time to review before wedding
- One party lacked mental capacity
- Agreement was not in writing
- Missing notarization
- Unconscionable terms at time of divorce
- Changed circumstances making enforcement unjust
Strengthening Prenup Enforceability
To maximize enforceability of a Massachusetts second marriage prenup:
- Both parties should have independent attorneys
- Sign at least 30 days before the wedding
- Include detailed financial disclosure schedules
- Avoid provisions that strip all assets from one party
- Include sunset clause for very long marriages
- Consider periodic review and amendment provisions
- Document that both parties read and understood all terms
Massachusetts Residency and Filing Requirements
While prenuptial agreements do not require filing with any court, understanding Massachusetts divorce requirements provides context for prenup planning. Under Mass. Gen. Laws ch. 208, §§ 4-5, if the cause of divorce occurred within Massachusetts, the filing spouse need only be domiciled in the state at filing. If the cause occurred outside Massachusetts, the filing spouse must have lived continuously in the Commonwealth for one year before filing.
Divorce filing fees total $215 to $305 (base fee plus surcharges) as of January 2026 at Massachusetts Probate and Family Court. The divorce process includes a 90-day nisi period before the divorce becomes final, plus time for negotiation if the prenup provisions are contested.
Frequently Asked Questions
How much does a prenup cost for a second marriage in Massachusetts?
A Massachusetts prenuptial agreement for a second marriage costs $2,500 to $5,000 total for both spouses with moderate complexity in 2026, based on attorney hourly rates of $250 to $500. Complex prenups involving business valuations or substantial assets can exceed $10,000 to $15,000 per side.
Can a Massachusetts prenup completely waive alimony?
Massachusetts courts generally enforce alimony waivers in valid prenuptial agreements, but the DeMatteo second-look doctrine allows judges to modify or invalidate provisions that would leave one spouse unable to support themselves after a long marriage. Partial limitations are more likely to survive than absolute waivers.
Does Massachusetts require both parties to have separate lawyers for a prenup?
Massachusetts does not legally require both parties to have independent attorneys for a valid prenuptial agreement under Mass. Gen. Laws ch. 209, § 25. However, the DeMatteo framework gives courts discretion to invalidate agreements where one party lacked legal counsel and did not fully understand the terms. Hiring independent counsel significantly increases enforceability.
How far in advance should we sign a Massachusetts prenup before the wedding?
Massachusetts couples should begin the prenup process 3 to 6 months before the wedding and sign the final agreement at least 30 days before the ceremony. While no specific timeframe is required by statute, signing within days of the wedding creates duress concerns that may invalidate the agreement.
Can a Massachusetts prenup protect my children from a previous marriage?
Yes, a Massachusetts prenuptial agreement can designate specific assets as separate property intended for children from a prior relationship, preventing those assets from becoming divisible marital property. This protection is particularly important because Massachusetts courts can divide all property including premarital assets and inheritances.
What makes a Massachusetts prenup invalid?
A Massachusetts prenuptial agreement may be invalidated if it lacks full financial disclosure, was signed under duress or coercion, is not in writing, is missing notarization, contains unconscionable terms, or if changed circumstances make enforcement unjust under the DeMatteo two-look test.
Can we include child custody arrangements in a Massachusetts prenup?
No, Massachusetts courts retain full authority over child custody and parenting time regardless of prenuptial terms. Any prenup clause attempting to predetermine custody arrangements or limit child support obligations is void and unenforceable.
Is Massachusetts a community property or equitable distribution state?
Massachusetts follows equitable distribution under Mass. Gen. Laws ch. 208, § 34, meaning assets are divided fairly but not necessarily equally. Unlike most equitable distribution states, Massachusetts makes all property divisible, including assets acquired before marriage, making prenuptial protection especially valuable.
Can I use an online prenup service for my Massachusetts second marriage?
Online prenup services like HelloPrenup offer Massachusetts templates for approximately $599, but these carry enforceability risks under the DeMatteo two-look test because no independent attorney reviews terms with each spouse. Given the 58% divorce rate for second marriages in the Northeast, professional drafting provides better protection for the additional cost.
What happens if my spouse refuses to sign a prenup in Massachusetts?
If your future spouse refuses to sign a prenuptial agreement, you must decide whether to proceed with marriage without asset protection. Massachusetts law cannot force anyone to sign a prenup. Consider whether the refusal reveals incompatible financial values worth addressing before marriage.
