What the law actually targets
Money laundering law is aimed at financial transactions involving the proceeds of certain listed crimes, when the person conducting them knows the money came from some form of unlawful activity. Prosecutors usually do not have to show that you knew which specific crime produced the funds, and in many cases the question is whether a transaction was designed to conceal the source or to promote the underlying activity. Some courts allow deliberately avoiding the truth about where money came from to be treated much like knowing it. Federal law separately reaches certain larger transactions with criminal proceeds even without concealment, and it treats deliberately evading bank reporting rules as its own offense. New York has parallel state offenses, which state prosecutors use in fraud, narcotics, and organized theft cases. Because the statutes are broad, laundering counts are frequently added to a case that is mainly about something else.
Banks, reports, and the paper trail
Most laundering investigations are built from bank records. Financial institutions file reports on large cash transactions and on activity they consider suspicious, and they are generally not allowed to tell a customer that a suspicious activity report was filed. An account closure or a request for source-of-funds documents can therefore be the first visible sign that a bank has concerns. If that happens, keep the letters and statements you receive, and collect records showing where the money came from, such as invoices, payroll records, loan papers, sale contracts, and tax returns. Avoid moving funds around, splitting deposits, or asking others to hold money for you, since those steps can look like the conduct the law targets. Should an agent call or visit, it is fine to say politely that you will respond after speaking with a lawyer.
How a first review is organized
We begin by identifying which transactions are being questioned and what underlying activity is alleged, because a laundering theory depends on a predicate offense. Then we look at what you were told at the time, who asked you to move or receive the money, and whether you were paid for doing it. Some clients turn out to be witnesses, or people who were used by someone else; others face real exposure and need to think about forfeiture, parallel civil claims, and, for non-citizens, immigration consequences. We also sort out whether the matter is federal, state, or both. From there we discuss whether to engage with investigators, respond to a seizure, or wait for more information.
