Ian Herbert represents global companies, executives, and trustees through government investigations and related litigation. Mr. Herbert has handled all aspects of multi-jurisdictional investigations, including complex legal analysis, global litigation strategy, and factual development. A member of the firm's Trust and Family Office and Anti-Money Laundering practice groups, Mr. Herbert has experience advising both individuals and entities, including multinational corporations, offshore trustees and financial services companies on a range of issues, including foreign bribery, tax fraud, and other financial crimes. 

Mr. Herbert has deep experience engaging with the Department of Justice (DOJ), Securities and Exchange Commission (SEC), and other federal and state regulators. Additionally, because his matters often involve a coordinated response to both U.S. and foreign regulators, Mr. Herbert is familiar with the relevant enforcement authorities outside the United States and is experienced in navigating the complex issues that occur in multi-jurisdictional investigations. Mr. Herbert has also represented individuals in federal district court on federal charges for racketeering, mail fraud, health care fraud, and obstruction of justice. 

Mr. Herbert maintains a robust pro bono practice focused primarily on representing individuals in criminal prosecutions and post-conviction proceedings. In 2017, he briefed, argued, and obtained a reversal of a criminal conviction in the D.C. Court of Appeals. In 2020, he secured the early release of another client under the First Step Act. 

Mr. Herbert writes regularly on issues related to white-collar criminal enforcement and money-laundering. He is an editor of both the Executives at Risk newsletter, which reports on noteworthy cases and investigations impacting corporate executives, and the Money Laundering Enforcement Trends newsletter, which focuses on developments in money laundering regulation and enforcement.
