Before marriage, parties may make a written contract concerning property or rights of action held when marriage occurs; its limitations take effect upon marriage as if in a deed.
Changed circumstances may make enforcement unconscionable if they leave a spouse without sufficient property, maintenance, or employment capacity for self-support.
Massachusetts has no UPAA-style general amendment section; a claimed change must satisfy the agreement, contract doctrine, and transaction-specific writing, deed, probate, or recording rules.
Massachusetts property schedule and recording rule
A clearly descriptive property schedule must be annexed, and the contract and schedule recorded before marriage or within ninety days afterward in the specified registry and where affected land lies.
Massachusetts recognition of divorce-related premarital settlements
Massachusetts recognizes premarital settlement of divorce-related property and spousal-support consequences, subject to validity, conscionability, and nonwaivable limits.
Rudnick found enforcement unconscionable where breached title promises and the agreement left an elderly spouse without marital property, alimony, or sufficient resources.
Austin enforced a negotiated waiver after finding execution validity and enforcement-time conscionability because meaningful assets and resources remained.
Courts retain authority over custody, care, maintenance, and education of minor children under child-focused standards and continuing modification power.
A postjudgment child-support agreement cannot bar modification without statutory findings, including guideline consistency and the child's best interests.
A premarital agreement cannot eliminate statutory authority to award funds or expenses needed to litigate validity and the domestic-relations proceeding.
Stacy enforced plain premarital language waiving claims to identified separate property at death and excluded it from the surviving spouse's intestate-share calculation.
Massachusetts disclosure and knowledge requirement
The waiving party must be informed of the other's worth or have adequate knowledge, and disclosure must permit a reasonable decision whether to proceed.
Massachusetts has no fixed waiting period; courts assess delivery, drafts, negotiation, counsel work, wedding pressure, and understanding on the full chronology.
These examples show how document facts can intersect with the cited sources. They do not predict a court result.

Does Massachusetts require a written agreement?

Massachusetts property schedule and recording rule

Nonrecording has the statute's stated third-party consequences; section 26 is not a universal divorce-enforcement rule.

DeMatteo v. DeMatteo, 436 Mass. 18, 762 N.E.2d 797 (2002)
Massachusetts execution-time fairness review
The first look considers knowledge, disclosure, waiver language, counsel, review opportunity, understanding, and absence of overreaching.
One-sidedness alone is insufficient, but stripping substantially all marital interests presents a serious issue.

DeMatteo v. DeMatteo, 436 Mass. 18, 762 N.E.2d 797 (2002)
Massachusetts independent-counsel factor
Separate counsel and meaningful review opportunity strongly inform knowing and voluntary execution but are not categorical execution formalities.
Counsel participation does not automatically cure deficient disclosure, misunderstanding, or pressure.

Massachusetts public-charge and child-interest limits
Potential public-charge consequences and conflict with a child's best interests exemplify limits private premarital terms cannot conclusively control.
These examples require current facts and law; they do not automatically invalidate the entire agreement.
Rudnick found enforcement unconscionable where breached title promises and the agreement left an elderly spouse without marital property, alimony, or sufficient resources.
Rudnick is fact-specific and creates no categorical age or duration rule.

Massachusetts support-waiver application
Austin enforced a negotiated waiver after finding execution validity and enforcement-time conscionability because meaningful assets and resources remained.
Austin supplies no universal formula for an enforceable support waiver.

Massachusetts contract interpretation of premarital terms
An enforceable agreement remains a contract whose language, definitions, schedules, triggers, and integrated obligations must be construed.
Validity and interpretation are separate; a valid agreement may not reach the asserted asset or remedy.

For a qualifying written property contract, limitations upon property rights take effect when marriage occurs as if contained in a deed.
This is specific to section 25, not a uniform-act applicability schedule.

Massachusetts child-support guideline boundary
Child-support orders follow current law and the guideline presumption, subject to lawful deviation findings rather than a prospective private waiver.
An agreement cannot freeze a future child's support entitlement.
A postjudgment child-support agreement cannot bar modification without statutory findings, including guideline consistency and the child's best interests.
Section 13 concerns postjudgment agreements, not general prenup execution.
