We Sue Wall Street

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


We have the experience and knowledge to handle your securities case.

Our team of Securities attorneys has decades of experience suing Wall Street, recovering millions of dollars in losses for our clients. While we handle many types of securities cases, most involve recovering retirement funds. We offer personalized, hands-on involvement in every case. We will tirelessly fight to recover your losses.


The Securities Lawyers have three main goals:

  1. To fight every day for our clients in court and arbitration to recover lost funds.
  2. To help clients get back on track by recovering funds lost or stolen as a result of their broker’s conduct.
  3. To 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.

Trusted Team of Attorneys


Our Securities Litigation Team

The head of our securities and litigation group, Sean Sweeney, served for four years on FINRA’s National Arbitration and Mediation Committee, which helps make the rules for the FINRA Arbitration Forum. Sean works alongside a talented team of focused and committed attorneys who provide personalized attention and high-quality representation. When you retain us for your case, you will receive personalized, hands-on involvement from a partner-level attorney.

Our team can handle numerous types of securities cases:

  • Securities fraud
  • FINRA arbitration.
  • Suitability Claims
  • Investment Fraud
  • Alternative Investment Claims

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

Our Fees


We only get paid if we win.

Our fee is a percentage of what we recover for you. There is no upfront fee. We understand that the last thing you want to do is take the risk of paying your lawyer’s fees upfront while 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 for as large of a recovery as possible.


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. Adherence to the rules of FINRA arbitration, which 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/zoom, allowing us to represent investors nationwide.

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.
