What to look for in a Boston prenup attorney

  • Bar-licensed in Massachusetts. Non-negotiable. An attorney from a neighboring state cannot represent you here.
  • Family-law focus, not generalist. Massachusetts prenup procedural rules (Mass. Gen. Laws ch. 209, §§25–26) are unforgiving; specialists handle them daily.
  • Active in Boston courts. Local court customs, scheduling, and judge familiarity matter when prenups get challenged.
  • Comfortable being one of two attorneys. Joint representation is one of the most common bases for invalidation later.
  • Flat-fee quote available. Boston rates are high enough that hourly billing can balloon; ask for a flat or capped fee once they\'ve scoped your situation.

Massachusetts applies the DeMatteo "two-look" fairness test: the agreement must be fair and reasonable at the time of execution AND not unconscionable at the time of enforcement. The dual review is uniquely demanding — agreements upheld in other states have been struck down in Massachusetts because circumstances at divorce made enforcement unconscionable.

Frequently asked questions

How much does a prenup lawyer cost in Boston?
In Boston, family-law attorney rates run $300–$480/hr. Total prenup fees range from $2,400 – $3,000 for a simple agreement to $6,000 – $12,000 for complex estates. Boston family-law rates run 15–25% above the Massachusetts state average. The DeMatteo "two-look" test applies statewide; high concentration of academic, biotech, and finance assets make Boston prenups particularly drafting-intensive.
How do I find a Boston prenup attorney?
Three reliable paths: (1) a vetted matching service like LegalMatch that screens family-law attorneys by Boston-metro practice; (2) the Massachusetts state bar's lawyer-referral service at https://www.massbar.org; (3) a referral from a family-law attorney you already know. Avoid general-practice attorneys — prenups have state-specific procedural rules best handled by specialists.
Do Boston courts apply different prenup rules than the rest of Massachusetts?
No — Massachusetts prenup law (Mass. Gen. Laws ch. 209, §§25–26) applies uniformly across the state, including Boston. What varies by metro: attorney rates, court backlogs, and the typical asset mix in local prenups. The substantive enforceability standard is the same statewide.
Can I sign a prenup in Boston and move to another state later?
Yes, but choice-of-law clauses don't always survive a move. If you later divorce in another state, that state's courts decide whether to apply Massachusetts law or local law. See the DeLorean v. DeLorean case for the textbook example. For couples with high relocation probability, drafting that satisfies multiple states' rules is the safer approach.
