About Sweeney Merrigan Law
Sweeney Merrigan works from Summer Street in Fort Point and names 18 people. Its own description claims more than $250 million recovered, which is the firm's figure and not one this directory has confirmed, so no amount appears on this profile.
Contingency fees, a free consultation and a 24 hour line, published, with every trust page pillar D looks for. 393 reviews at 4.9.
What this firm has earned Every one from a measured value, with the evidence behind it
LFL Verified 2026
Every eligibility gate this firm's state allows us to check has been checked and held: licensure, discipline, entity, website and footprint. Certification additionally requires a score of 70.
No public discipline
No attorney this firm names appears as the respondent in any of the 168 published discipline decisions of the Supreme Judicial Court of Massachusetts on the discipline of attorneys, on the recommendation of the Board of Bar Overseers, 1975 to 2025. Published decisions record what has been decided, so this covers a disbarment or suspension on the record and not whether a registration is current today.

A high rating is easy at low volume and hard to hold at this one. Pillar C scores it against the market rather than against five stars.

G1 LicensureNot published by MAMassachusetts does not publish an attorney register we can query, so licensure is not verified here. The state's own attorney search is the place to check it.
G2 DisciplineNo attorney this firm names appears as the respondent in any of the 168 published discipline decisions of the Supreme Judicial Court of Massachusetts on the discipline of attorneys, on the recommendation of the Board of Bar Overseers, 1975 to 2025. Published decisions record what has been decided, so this covers a disbarment or suspension on the record and not whether a registration is current today.
G3 Entity & officeNot published by MA1 physical location verified on Google Business Profile. Massachusetts publishes no business register we can query. The Secretary of the Commonwealth's corporate search answers a request for its robots file with a 403 and its search page with a redirect loop, and the state runs no open data portal carrying the register. This is a limit of the published record and not something the firm can change.
G5 WebsiteSite has served over HTTPS, a working phone number published, 18 named attorneys published.
G6 Footprint393 public client reviews across 1 Google listing, above the 10 minimum, and the firm's domain has been registered since 2010-10-20, so it has been operating for more than a year

What the firm publishes itself
Sweeney Merrigan Law, LLP lists 31 case results on its own website, across 8 case types. The page carries no disclaimer about past results. We have read the page and counted what is on it. We have not confirmed the amounts, so none are repeated here.
Results are specific to their facts and do not guarantee similar outcomes. Firms submit results through their claimed profile; only results we can substantiate are published with amounts.
The firm’s people the firm names its people without saying who among them practises law · 18 more people are named by the firm without a role, so we do not call them attorneys
Also named by the firm
The firm lists these people among its team and prints no role beside the names, so we do not describe them as attorneys.
