What Is Money Laundering under New York Law?

The statute requires that funds or property originate from a "specified unlawful activity," which encompasses felonies including drug trafficking, fraud, theft, extortion, and numerous other serious crimes. Courts have held that the government must prove the predicate crime by clear and convincing evidence or, in some procedural contexts, by a preponderance of the evidence depending on the stage of proceedings. The nexus between the property and the predicate offense must be direct; merely suspecting criminal origin is insufficient, and a defendant's genuine but mistaken belief that funds are legitimate can negate the requisite knowledge element.

Prosecution for money laundering requires proof of knowledge, not mere negligence or recklessness. A defendant must either know that property represents proceeds of specified unlawful activity or act with intent to promote the underlying crime or conceal the criminal source. This heightened mental state distinguishes money laundering from structuring (breaking deposits into smaller amounts to avoid reporting thresholds), which carries separate penalties and different proof burdens. Defense counsel often challenge the government's evidence on knowledge and intent, particularly when a defendant claims reliance on representations from third parties or lack of awareness of the criminal source.

Banks, money services businesses, and other financial institutions face affirmative compliance duties under the Bank Secrecy Act and the USA PATRIOT Act. These entities must maintain customer identification programs, file Suspicious Activity Reports (SARs) when transactions exceed certain thresholds or exhibit indicators of criminal origin, and implement anti-money laundering (AML) programs. Failure to implement adequate anti-money laundering controls can result in civil penalties, enforcement actions by federal regulators, and criminal liability for responsible officers. Compliance defects can also create evidentiary gaps that prosecutors exploit in criminal cases.

In New York County Criminal Court and similar trial-level forums, money laundering charges often proceed alongside predicate felony counts. Prosecutors must establish the predicate offense through evidence such as witness testimony, financial records, or controlled substance lab reports before the jury can consider the money laundering count. Courts have held that a verdict of acquittal on the predicate offense does not automatically bar conviction on money laundering if sufficient evidence exists of the defendant's knowledge of criminal source from other sources. However, procedural defects in establishing the predicate (such as late disclosure of exculpatory evidence or failure to comply with discovery obligations) can create grounds for suppression or mistrial, particularly when the defense lacks adequate time to investigate and challenge the government's theory.

Effective compliance requires ongoing assessment of customer risk profiles and transaction patterns. High-risk indicators include cash-intensive businesses, frequent international wire transfers without clear commercial purpose, transactions with customers in jurisdictions with weak anti-money laundering frameworks, and use of shell companies or complex ownership structures. Documented risk assessments and written policies create a defense against charges of willful blindness or reckless indifference. When a business discovers suspicious activity, prompt filing of a SAR and cessation of the relationship demonstrates good-faith compliance effort and may limit liability exposure.
