Prenuptial Agreement Attorney Fees in Boston
Prenuptial agreement lawyer fees in Boston, Massachusetts average about $3,700 — roughly 148% of the U.S. average and in line with the Massachusetts state average of $3,700.
What this typically includes
Consultation, drafting or reviewing the agreement, exchanging the required financial disclosures, and revisions through signing. Because nothing is filed with a court, there are no court costs — the fee is for legal work only.
Massachusetts has not adopted the Uniform Premarital Agreement Act, so prenup enforceability is governed by Massachusetts’s own statutes and case law, which can apply stricter or different requirements.
Prenuptial agreement attorneys in Massachusetts usually charge a flat fee to draft or review the agreement, and for it to hold up each spouse generally needs independent counsel and full financial disclosure. Because a prenup is not filed with a court, there are no court costs. State enforceability rules vary and evolve, so confirm the current requirements locally.
