Protecting Investors, Recovering Losses

Trust Us To Handle Your Case


— Since 1970 —

The Securities Lawyers protect investors by lobbying Congress and working with FINRA (the Financial Industry Regulatory Authority) to enact laws and regulations that prevent retirement funds from being lost in the first place. At the same time, we fight every day for our clients in court and arbitration to recover those funds they have already lost. Our primary focus is to help our clients get back on track towards the retirement they were building by recovering the funds that were lost or stolen as a result of their broker’s conduct.

Decades Of Experience


Our team of Securities attorneys have extensive experience, helping our clients recover millions of dollars in losses — with a majority of our cases involving the recovery of retirement funds. We only get paid if we win, and offer personalized, hands-on involvement in every case. The head of our securities and litigation group, Sean Sweeney, serves on FINRA’s National Arbitration and Mediation Committee, which helps make the rules for the FINRA Arbitration Forum. We are on the inside. And we are also on YOUR side.

Trusted Team of Attorneys


Our Securities Litigation Team

Attorney Sean M. Sweeney is the Head of the Securities Litigation Group that works alongside a talented team of attorneys on a wide range of cases, including securities fraud, stock broker employment disputes, and FINRA arbitration. A strong commitment and focus is placed on providing the personalized attention that one would receive at a small law firm, while still receiving high-quality representation. When you retain us for your case, you will receive personalized, hands-on involvement from a partner-level attorney.

“WE ONLY GET PAID IF WE WIN.
Our Fee is a percentage of what we actually recover for you. There is no upfront fee.”

THE SECURITIES LAWYERS

Our Fees


For any client with a potential securities claim, we will provide:

  1. Free consultation to discuss and review your claim.
  2. An explanation of the time, commitment, and process for FINRA arbitration (the most common forum for these claims).
  3. WE ONLY GET PAID IF WE WIN. Our fee is a percentage of what we actually recover for you. There is no upfront fee.

We understand that by the time you realize what has happened in your account, the last thing you want to do is throw more money at a lawyer trying to recover what was lost. That is why we work on a contingent fee basis for these claims. This aligns our interests with yours, which is to resolve the matter as quickly as possible for as large of a recovery as possible.

Nationwide Services


The Rules of FINRA Arbitration…

dictate that the final hearing takes place in the FINRA service location closest to where the claimant (the investor) lives. However, every other aspect of the proceeding is handled on the FINRA web portal and over the phone. This means we can represent investors nationwide. We represent clients in a broad range of cases, including: misrepresentations, customer specific and reasonable basis unsuitability, breach of fiduciary duty, uniform securities law violation, unjust enrichment, and negligence/unsuitable recommendations.
