White Collar Criminal & Federal Defense Attorneys Trusted Nationwide
Allegations involving OFAC sanctions or export control violations are not routine regulatory issues—they are treated as national security matters. These cases often imply exposure to terrorism financing, nuclear proliferation, or dealings with hostile foreign actors, placing individuals and companies under immediate and intense federal scrutiny.
The Office of Foreign Assets Control (OFAC) administers and enforces U.S. economic and trade sanctions designed to protect U.S. foreign policy and national security interests. When violations are alleged, investigations move quickly, penalties escalate rapidly, and reputations are placed at risk long before any formal charges are filed.
At Chapman, Dowling & Mallek, we understand that these cases demand discretion, technical mastery, and a defense strategy calibrated for regulators and prosecutors—not headlines.
Effective defense in this arena requires far more than reacting to enforcement actions. It demands a proactive, layered strategy built to contain exposure, preserve credibility, and resolve matters efficiently.
Our defense approach includes:

Key legal authorities include:
Understanding how these laws intersect is essential to mounting a credible defense.
