The New York office of Kasowitz Benson Torres LLP is home to a deep bench of securities litigators who handle both defense and plaintiff work but focus predominantly on the latter. The firm handles both direct securities fraud and opt-out cases, frequently acting for prominent hedge funds, mutual funds and pension funds in high-profile cases. It continues to be involved in cases concerning residential mortgage-backed securities, acting for trustees of RMBS transactions, and it is a key adviser to investment funds in disputes arising from the trillions of dollars in complex financial assets held in securitization trusts. Sheron Korpus, Michael Hanin and Stephen Tountas (who is ‘a talented securities lawyer – very knowledgeable and strategic and experienced‘) are the lead partners. Leading trial lawyer Marc Kasowitz, who scored a major victory for MBIA Insurance Corporation in an RMBS case by securing a $600m payout from Credit Suisse in 2020, also plays a central role in the practice. Uri Itkin left the firm in May 2022.
