A range of the largest national investment banks, insurance companies, and mortgage and consumer lenders employ Mayer Brown‘s counsel on complex disputes in the financial services sector, in both high-stakes antitrust and post-transactional litigation as well as regulatory investigations. The firm has notable experience at the appellate and Supreme Court levels in civil lawsuits. Christopher Houpt and Matthew Ingber are the main names in advisory work for banks, financial service providers, and commercial SPVs on mandates against investors, creditors, and class action groups. Acclaimed as ’the go-to lawyer for civil litigation in the financial and banking sectors‘, Mark Hanchet has led on complicated cross-jurisdictional fraud cases for international banks, and Chicago’s Greg Deis is the firm’s investigations specialist, handling both regulatory and criminal investigations into charges of fraud, money laundering, market manipulation, and trade surveillance. Unless otherwise mentioned, all attorneys are based in New York.
