What to do When Under Investigation For Money Laundering Defense

July 2026 · 6 min read · John D. Kirby, Former Federal Prosecutor

When you receive notification that a federal investigation related to money laundering under 18 USC 1956 has begun against you, your immediate reaction should be measured and thoughtful. Investigations typically start with preliminary inquiries by federal agencies such as the FBI, DEA, IRS-CI, or FinCEN, often prompted by suspicious activity reports filed by financial institutions.

The moment you become aware of an investigation, it is crucial to take several critical steps within the first 48 hours. First and foremost, seek legal counsel immediately from a reputable federal defense attorney who specializes in money laundering cases. Early representation can significantly impact the outcome of your case by allowing your lawyer to engage with investigators on your behalf before any formal charges are filed.

Do not attempt to communicate or cooperate directly with law enforcement without an attorney present, even if you feel that you have nothing to hide. Any voluntary disclosure or admission at this stage can be used against you in subsequent proceedings. Instead, focus on preserving all documents and communications relevant to the investigation, such as emails, financial records, and any electronic data.

It is imperative to understand what NOT to do during an investigation. Avoid making spontaneous decisions that might seem like efforts to mitigate the situation but could actually exacerbate it. This includes destroying or altering evidence, lying under oath, or attempting to flee from authorities. These actions can lead to additional charges and severe penalties.

Preservation of documents is a critical aspect of managing an investigation. Ensure all relevant files are secured in a safe location where they cannot be tampered with or destroyed accidentally. This includes both digital and physical records that may contain information pertinent to the case, such as transaction histories, business correspondence, and personal communications.

Remember, federal investigations involving money laundering under 18 USC 1956 can be complex and multifaceted, often requiring knowledge of intricate financial transactions and legal nuances. Your response must be equally sophisticated and carefully considered to protect your rights and interests throughout the investigative process.
