White Collar Criminal & Federal Defense Attorneys Trusted Nationwide
Allegations involving violations of U.S. sanctions and embargo laws are among the most serious matters a business or individual can face. Even a single misstep can trigger sweeping investigations, crippling fines, criminal exposure, and years of regulatory scrutiny. Beyond the legal consequences, OFAC matters place reputations, careers, and global operations at immediate risk.
At Chapman, Dowling & Mallek, we approach OFAC matters with discretion, precision, and a clear objective: protecting our clients while controlling exposure at every stage of the process.
OFAC defense is not a one-size-fits-all exercise. From a legal standpoint, it is a highly strategic, multi-layered effort designed to defend individuals, executives, and companies accused of violating economic sanctions administered by the Office of Foreign Assets Control.
In many cases, effective defense begins before formal allegations are made. This may include proactive compliance reviews, internal investigations, and risk assessments intended to identify and contain potential exposure early.
When enforcement action is underway, the focus shifts to a rigorous defense strategy that may include:
OFAC enforcement actions often arise from routine international activity that becomes legally perilous due to sanctions restrictions. Common allegations include:
OFAC investigations are led by the Office of Foreign Assets Control, which has broad civil enforcement authority. However, OFAC matters frequently expand into multi-agency investigations, including:

Executives, officers, and organizations trust us because we understand complex financial investigations, move quickly to protect leadership and enterprise value, and focus on achieving the best possible outcome with minimal disruption to business operations and reputations.
OFAC enforcement is unforgiving. Regulators expect precision, speed, and compliance—and they penalize hesitation and missteps. Attempting to navigate a sanctions investigation without seasoned legal counsel often compounds the damage.
At Chapman, Dowling & Mallek, we defend OFAC matters with the discretion, technical command, and strategic discipline these cases demand. Our role is to protect your rights, limit exposure, preserve your reputation, and pursue the most favorable resolution possible—whether through early intervention, negotiation, or aggressive defense.
If sanctions exposure is even a possibility, early legal guidance is not optional. It is decisive.
Defense in cases involving healthcare fraud, false claims, and regulatory violations.
Quiet. Strategic. Decisive.
Every federal case is built long before the courtroom—and often ends before it ever reaches one. Led by a former federal prosecutor and U.S. Marine Corps Judge Advocate—supported by former federal investigators—our process is designed to resolve matters quietly, strategically, and with precision.
We engage early, often before formal charges are filed. By understanding how federal agencies build cases, we work to shape the investigation, limit exposure, and control the narrative from the start.
Our credibility and insight into federal procedure allow us to communicate effectively with prosecutors and investigators—often achieving resolution through dialogue rather than litigation.
We combine investigative experience with advanced data analytics and AI to uncover patterns, test government theories, and identify weaknesses in complex financial, digital, or regulatory evidence.
Whether through negotiation or trial, our approach is tailored to secure the best outcome — quietly, strategically, and decisively, with every step focused on protecting our clients’ reputations and results.
