About

Provided by León Cosgrove Jiménez, LLP

León Cosgrove Jiménez, LLP is a litigation firm comprised of former federal law clerks and top-tier trial lawyers from AmLaw 100 firms. Since January 2013, the firm's national litigation platform and special proficiency in financial services litigation has led to the firm being chosen to handle over 1,000 of JPMorgan Chase’s matters in Florida. Highly focused and trial-ready teams represent clients in high-stakes plaintiff and defense matters across a wide range of practice areas, industries, and venues throughout the United States—often going up against and defeating, established global legal brands.


León Cosgrove Jiménez, LLP is the litigation powerhouse for one of the world’s largest banks, several large global retailers, energy companies, as well as domestic and foreign governments. Its lawyers have litigated for defrauded plaintiffs in the Scott Rothstein Ponzi scheme and for Bank of NY Mellon in a case brought by the Russian Federation. They recovered $120 million for CDR Creances (an instrumentality of the French government) after a French bank was defrauded in a sophisticated international scheme involving dozens of shell companies to hide the collateral for a defaulted bank loan. They recovered $76 million in a construction defect and fraud case on behalf of a large energy company in an international arbitration. The firm has also represented the state of Florida in a dispute involving $30 million owed the state annually under its landmark 1997 tobacco settlement.
