We Sue Wall Street

Protecting Investors, Recovering Losses

TRUST US TO HANDLE YOUR CASE

Recover your Investment Losses

The Securities Lawyers fight every day for our clients in court and arbitration to recover those funds they have lost due to their stockbroker’s or financial advisor’s misconduct. 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 or financial advisor’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:

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

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 clients with a potential securities claim, we 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.

When I contacted Sean by email about my GWG investment Sean called me right away. We talked for about 30mins, that's when I found out it was about all the investments, I was wrongly put into. Sean Sweeney and his team mediated and recovered on my case. Sean stated it would take a year for the case to be completed and he stayed on time. Sean's team stayed in contact with me and kept me informed and answered all questions. During the hearing Sean was very accurate on how the hearing would go and advised me all the way through. Highly recommend Sean Sweeny with Halling & Cayo, Security Lawyer

Sean Sweeney and the entire team at Halling & Cayo were great to work with! They systematically handled my case and achieved a positive outcome. From the day I made initial contact with them, to the day they sent my settlement check was less than 4 months. They were very thorough and responsive with all communication every step of the way.

Sean was easy to work with. He really guided us through the process. However, we came up a little short on our expected settlement amount. We do admire him for having the courage to take on such a challenging legal battle. We will always be grateful for what he has done for us.

Great lawyers. Sean Sweeney and his staff where with us 100% of the way with our case and was resolved quickly. Loved the outcome and their due diligence. When the other party saw that these where experienced SEC attorneys they avoided mediation and agreed with our terms before a lawsuit was filed. The lack of a threat was not left out. Quick results after their first display of power. Very happy with results.
