Federal Money Laundering Charges and Defenses
The charge that transforms every other count on a federal indictment is money laundering. A wire fraud case carrying a sentencing range of twelve to eighteen months becomes, with the addition of a Section 1956 count, a case in which the court is contemplating a decade or more. Federal prosecutors understand this arithmetic, and they have understood it for some time.
What most defendants do not perceive, until they are seated across the table from counsel reviewing the indictment for the first time, is that the money laundering charge is not about elaborate offshore accounts or layered shell corporations. In the majority of federal cases, the conduct alleged as money laundering is something far less remarkable: depositing a check, compensating a vendor, transferring funds between two accounts at the same institution. The statute reaches further than the popular imagination of it, and that distance is where the government constructs its case.
Section 1956 and Section 1957
The federal money laundering statutes occupy two sections of Title 18, and the difference between them is not academic. Section 1956 carries a maximum sentence of twenty years per count. Section 1957 carries ten. The paradox is that Section 1956, the harsher provision, demands more of the government to prove.
Under Section 1956, the prosecution must demonstrate that the defendant engaged in a financial transaction involving proceeds of what the statute terms “specified unlawful activity,” and that the defendant acted with a particular intent: to promote further unlawful activity, to conceal the nature or source of the funds, or to avoid a transaction reporting requirement. That intent element is, if we are being precise, the load-bearing wall of a Section 1956 case. Without it, the structure does not hold.
Section 1957 asks less. The government need only prove that the defendant conducted a monetary transaction exceeding ten thousand dollars in criminally derived property. No intent to conceal is required. No intent to promote. The bare act of spending or depositing money derived from a qualifying offense, in a sufficient amount, constitutes the violation.
The list of qualifying offenses is itself worth attention. The statute designates certain federal crimes as “specified unlawful activities,” and the catalogue is extensive: mail and wire fraud, drug trafficking, RICO violations, healthcare fraud, tax evasion, and a range of other federal offenses that runs to several pages of the United States Code. The breadth is not incidental.
A fraud defendant who deposited the proceeds of a wire fraud scheme into a business account has, under the government’s theory, committed a financial transaction designed to promote unlawful activity. A tax evasion defendant who spent unreported income on business expenses has conducted a monetary transaction in criminally derived property. The statute does not require that the defendant did anything unusual with the money. It requires that the money touched the financial system at all.
The Knowledge the Government Claims It Does Not Need
For a conviction under either statute, the government must prove that the defendant knew the funds were derived from some form of unlawful activity. The natural assumption is that this requirement provides meaningful protection: if you did not know the money was illicit, you cannot be guilty of laundering it.
The willful blindness doctrine has, in practice, rendered that assumption unreliable.
Federal courts have held, and the Supreme Court affirmed in Global-Tech Appliances, Inc. v. SEB S.A., that a defendant who deliberately avoids learning facts that would confirm the illicit origin of funds is as culpable as a defendant who possesses actual knowledge. The doctrine requires two conditions: the defendant must have believed there was a high probability that the funds were criminally derived, and the defendant must have taken deliberate action to avoid confirming that belief. In practice, the second condition is satisfied by silence. By not asking.
Whether this doctrine has expanded beyond its original justification is a question the courts have not answered with the clarity practitioners would prefer. The original rationale, formulated in the context of drug courier cases, was that a person who carries a sealed package across a border and declines to examine its contents should not escape liability by claiming ignorance. The extension of that logic to financial transactions, where the “package” is a wire transfer and the person is a business owner processing payments, is a matter on which reasonable attorneys disagree, though the disagreement tends to confirm the rule rather than unsettle it. The practical effect, however, is not in dispute. A defendant who received payments from a source that exhibited red flags, who processed those payments without inquiry, and who cannot demonstrate affirmative due diligence will face a jury instruction equating that silence with knowledge.
The instruction itself is worth pausing over. It tells the jury that they may treat the defendant’s deliberate avoidance of knowledge as the legal equivalent of actual knowledge. This is not a presumption the defendant can rebut with character testimony or assertions of good faith. It is a factual determination left to twelve people who have already heard the government’s evidence about what the defendant should have known. The instruction does the rest of the work.
The Merger Problem
The most serious structural challenge to the government’s use of money laundering charges is one that most defendants never encounter until their attorney raises it. It is called the merger problem, and it concerns the relationship between the money laundering statute and the predicate offense that generated the funds.
The problem operates as follows. If every expenditure of criminal proceeds constitutes a separate money laundering offense, then virtually any crime that generates revenue will “merge” with money laundering. An illegal gambling operation that compensates its employees has laundered money. A fraud scheme whose operator deposits receipts in a bank account has laundered money. The predicate crime and the laundering charge become the same act charged twice, with the laundering charge carrying a sentence that dwarfs the original.
In United States v. Santos, decided in 2008, the Supreme Court confronted this problem directly. The defendant, who operated an illegal lottery in Indiana, had been charged with money laundering based on payments to his runners and to winning bettors; Justice Scalia, writing for the plurality, interpreted the statute’s use of the word “proceeds” to mean “profits” rather than “gross receipts,” reasoning that the alternative would effectively double the punishment for every revenue-generating crime in the federal code by collapsing the predicate offense into the laundering charge without any additional culpable conduct. The Court found no indication that Congress intended this result.
Santos was, for defense attorneys, a brief window of light. Congress responded by amending Section 1956 to define “proceeds” as any property derived from or obtained through the commission of the specified unlawful activity. The amendment did not resolve the merger concern so much as legislate past it. The tension persists.
Courts in several circuits have continued to hold that the money laundering offense and the underlying offense must be meaningfully distinct to support separate convictions. In the Tenth Circuit, that principle is stated explicitly. In others, the question surfaces in motions to dismiss, at sentencing, and in appellate opinions that acknowledge the problem without reaching a settled resolution. Whether the court intended to leave this gap or merely failed to close it is worth considering.
Three cases in this office alone, over the last eighteen months, turned on whether the financial transaction alleged as laundering was genuinely separate from the specified unlawful activity that produced the funds. In each, the government’s theory was that the defendant promoted the underlying offense by depositing its receipts. In each, the defense argued that depositing receipts is not a distinct act of laundering; it is the unremarkable mechanics of possessing money. The distinction sounds abstract until the sentencing exposure hinges on it.
Whether the current statutory language forecloses the merger defense entirely or merely narrows it is a question I am less certain about than the preceding paragraphs might suggest. The case law is fractured, and the circuits do not agree.
Forfeiture
Before a money laundering case reaches trial, the government has the authority to freeze the defendant’s assets. Under 18 U.S.C. Section 1956(b), a federal court can issue a restraining order preserving any property subject to forfeiture, which includes property involved in or traceable to the offense. The practical consequence is that a defendant can lose access to bank accounts, real property, and vehicles before the government has proven anything at all.
The forfeiture provisions are broad. If criminal proceeds were commingled with legitimate funds in a single account, the government will argue that the entire account is tainted. If proceeds were used as a partial down payment on a property, the property itself becomes subject to forfeiture. The government’s theory in these cases is not proportional.
A defendant who requires those assets to retain counsel, to sustain a business, or to maintain a household is, at the moment the restraining order issues, in a position that determines every subsequent decision in the case. The forfeiture does not wait for conviction. It arrives with the indictment.
What a Defense Requires
The standard enumeration of money laundering defenses includes lack of knowledge, lack of intent, constitutional violations, and procedural challenges under the Federal Rules. These are accurate as categories; they are insufficient as strategies.
A defense in a federal money laundering case begins with the specified unlawful activity. If the government cannot prove the predicate offense, the money laundering charge collapses entirely. This is not a secondary point. In cases where the predicate is weak (a mail fraud charge built on ambiguous evidence, a tax evasion theory that depends on the government’s reading of contested deductions), the money laundering defense is a defense of the underlying case. We approach these cases by treating the predicate as the primary target.
The knowledge element presents its own ground. The government must prove, even under the willful blindness standard, that the defendant was aware of facts creating a high probability of criminal origin. In cases involving legitimate businesses that process large volumes of transactions, the question of what the defendant knew is often genuinely contested. Bank records, email correspondence, compliance protocols, and the testimony of employees become relevant. We retain forensic accountants early, not because every case requires one, but because the government will have already retained its own. The narrative those numbers construct is difficult to displace once the jury has absorbed it.
The transaction itself must qualify as a “financial transaction” affecting interstate or foreign commerce. Not all transfers of money satisfy this definition. The requirement is technical, and in a small number of cases, it provides an opening. The statute of limitations is five years. In investigations that extend over years before an indictment is returned, the limitations question demands attention to the dates of specific transactions.
Constitutional challenges surface where they are expected: the Fourth Amendment governs searches of financial records, the Fifth Amendment governs compelled testimony and self-incrimination, and the Sixth Amendment right to counsel intersects with forfeiture in ways that determine whether a defendant can afford the representation the case requires. The intersection is not something most defendants anticipate.
A money laundering charge does not describe what a person did with money. It describes what the government believes the person intended by doing it. The distance between those two propositions is where a defense is constructed.
Every federal money laundering prosecution is, at its foundation, two cases: the case for the predicate crime and the case for what happened to the money afterward. The government benefits from treating these as a single narrative. The defense benefits from separating them.
The separation requires counsel who comprehends not only the statutes but the arithmetic of federal sentencing, the mechanics of forfeiture, and the particular pressure a money laundering charge places on a defendant’s capacity to mount a defense at all. A first consultation is where that understanding begins. It costs nothing, and it assumes nothing except that the situation warrants examination.
