Maura McDevitt is an associate in Mayer Brown’s New York office and a member of the Litigation & Dispute Resolution group, currently on secondment to the London office. Her practice focuses on complex commercial and financial services litigation and investigations. Maura's experience includes representing multinational corporations and other clients in securities and commodities litigation, including RMBS litigation and shareholder derivative lawsuits, cross-border government and internal investigations, and benchmark rate class actions. She also advises clients on the implementation of policies and procedures designed to assist in meeting information preservation and electronic discovery obligations, particularly in the UK and Europe. Many of Maura’s recent experiences resulted in Law360 recognizing Mayer Brown as a “Banking Group of the Year” in 2018 and 2017.

Maura has significant experience leading and coordinating all aspects of complex litigation at all stages of a case, including written motion practice, fact and expert discovery, and trial preparation in both bench and jury trials, including pre-trial submissions, dispositive motions, motions in limine, witness preparation, direct and cross-examination outlines, and proposed jury instructions and verdict forms.

Maura maintains an active pro bono practice at Mayer Brown. Recent successes include securing the highest compensable rating for a service-connected disability appeal before the Board of Veterans’ Appeals and the issuance of a nationwide preliminary injunction against the Trump Administration’s immigration fee waiver rule.

Maura joined Mayer Brown in 2015, after earning her JD from Columbia Law School, where she was awarded the Parker School Certificate of Achievement in International and Comparative Law, and spent six months at the Université de Paris I Panthéon-Sorbonne and Sciences-Po Paris where she studied European Union law, international litigation and arbitration, and competition law.

Maura was previously seconded to the litigation and enforcement divisions of two international financial institutions, Credit Suisse’s General Counsel Litigations and Investigations Group and HSBC’s Litigation and Regulatory Enforcement Group, where she worked on a variety of civil litigation and regulatory enforcement matters.
