Chris Houpt is a co-chair of Mayer Brown's Banking & Finance Litigation group, concentrating on banking and finance matters, particularly cases involving cross-border issues; securitization, structured finance, and derivatives; and asset turnover. Recognized as a Leading Lawyer in Financial Services Litigation by Legal 500, and a Rising Star by Law360 (for Banking) and the New York Law Journal, Chris has represented securitization trustees and investors in and out of litigation. Those engagements include the first case against an RMBS trustee to go to trial, which resulted in a complete victory for the trustee, three appeals limiting trustee liability, and judicial instruction (Article 77) proceedings relating to some of the largest RMBS underwriting and servicing settlements. Partly as a result of those wins, plaintiffs in three cases against Chris’s trustee clients have simply walked away, after years of litigation. Chris is also active in securitization industry groups and was the co-chair of SFIG’s RMBS 3.0 Litigation and Arbitration Workstream.

Chris has also represented foreign banks in US litigation and is experienced in coordinating lawsuits in multiple forums. Most recently, he represented a German bank in a successful jury trial involving municipal bond reinvestment contracts.

Chris began in Mayer Brown's Supreme Court & Appellate practice. His appellate experience includes briefs in the US Supreme Court, federal Courts of Appeals, and state appellate courts, as well as oral arguments in the New York Appellate Division.

Chris joined Mayer Brown in 2005, after serving as a foreign law clerk for the Honorable Aharon Barak, President of the Supreme Court of Israel. During law school, Chris was an editor on the Harvard Law Review and a Teaching Fellow for the Harvard Economics Department. Previously, he worked in portfolio management at the D. E. Shaw Group and as a manager in the finance department of Covad Communications. Chris passed the National Futures Association’s Series 3 exam in 2000 and has completed the first two levels of the Chartered Financial Analyst® program.
