18 U.S.C. 1957 makes it a federal crime to knowingly conduct a monetary transaction of more than $10,000 through a financial institution using money that came from certain serious federal offenses. A conviction carries up to ten years in prison, fines that can reach twice the value of the funds involved, and mandatory forfeiture of the property tied to the transaction. Unlike the broader money laundering statute at 18 U.S.C. 1956, this one does not require the government to prove you were trying to hide anything or promote further crime. Knowledge that the money was dirty, plus a qualifying transaction, is enough.
What the Government Has to Prove
Three elements, each beyond a reasonable doubt.
First, you knowingly engaged or attempted to engage in a monetary transaction. The statute defines that as a deposit, withdrawal, transfer, or exchange of funds through a financial institution. You do not need to know the transaction was illegal. You do need to know you were carrying it out.
Second, the transaction involved criminally derived property worth more than $10,000, and those proceeds trace back to a “specified unlawful activity” defined by cross-reference to section 1956. You do not have to be the person who committed the underlying crime. Knowingly moving someone else’s drug proceeds through a bank account creates the same exposure as moving your own.
Third, the transaction passed through a financial institution. The definition, borrowed from 31 U.S.C. 5312, is broad: banks, credit unions, broker-dealers, casinos, insurance companies, and many other entities are covered. This requirement is what separates section 1957 from section 1956 and what makes the statute so useful to prosecutors going after money that touches the legitimate financial system.
How Section 1957 Compares to Section 1956
Section 1956 is the traditional money laundering statute, and it demands more from prosecutors. To convict under 1956, the government must show you knew the funds came from illegal activity and that you intended to promote further criminal activity, conceal the source of the money, or avoid a reporting requirement.
Section 1957 drops that intent requirement almost entirely. A drug trafficker who deposits $15,000 of drug proceeds into a checking account has violated section 1957 the moment the deposit clears, whether or not the deposit was designed to hide anything. The tradeoff for prosecutors is a lower ceiling: ten years under section 1957 versus twenty years under section 1956.
The $10,000 Threshold and the Tracing Problem
The $10,000 floor is fixed by statute and is not adjusted for inflation. It applies transaction by transaction, not cumulatively. Five separate $5,000 deposits do not add up to a section 1957 offense on their own, though breaking transactions up deliberately to stay under reporting thresholds can violate the anti-structuring statute at 31 U.S.C. 5324.
The real fight in many cases is tracing. When dirty money sits in the same account as legitimate funds, the government cannot simply point to a large withdrawal and call it a section 1957 violation. It has to prove the specific transaction involved more than $10,000 in criminally derived property. In United States v. Rutgard, the Ninth Circuit reversed section 1957 convictions in a medical fraud case because prosecutors could not show the challenged withdrawals consisted of more than $10,000 in fraud proceeds rather than legitimate money that happened to be in the same account. The court noted that commingling can defeat the statute when the charge is built around a withdrawal, unless the government can show the entire account was made up of criminal proceeds.
That tracing weakness is often the most productive ground for the defense.
Which Crimes Count as Predicates
Not every offense qualifies. Section 1957 borrows its list of “specified unlawful activities” from section 1956(c)(7), which covers more than 250 federal and foreign offenses grouped into several broad categories:
- Racketeering predicates listed in the federal RICO statute, including fraud, bribery, extortion, gambling, and counterfeiting.
- Drug trafficking offenses under the Controlled Substances Act, including continuing criminal enterprises.
- Crimes against foreign nations, such as drug trafficking, violent crimes, foreign bank fraud, public corruption, export control violations, and human trafficking, when the transaction touches the United States.
- Federal health care fraud and related offenses.
- Certain federal environmental crimes.
- A long list of additional federal offenses including terrorism, bank fraud, wire fraud, mail fraud, immigration violations, and theft from federally funded programs.
Prosecutors do not need to separately convict you of the underlying crime. They only need to prove the funds trace back to one of these activities.
Prison Time and Fines
The maximum prison sentence is ten years. Actual sentences turn on the U.S. Sentencing Guidelines, which weigh the dollar amount involved, the defendant’s role, prior criminal history, and any aggravating circumstances. Terms are often substantial when the underlying conduct involves large-scale fraud, drug trafficking, or public corruption.
Fines follow a “greatest of” formula. The court picks the highest of three options: the standard Title 18 fine (up to $250,000 for an individual or $500,000 for an organization), or up to twice the value of the criminally derived property involved in the transaction. Multiple counts stack, and total exposure can reach the millions quickly.
Mandatory Forfeiture
Forfeiture is not discretionary. Under 18 U.S.C. 982, a section 1957 conviction requires the sentencing court to order the defendant to forfeit any property involved in the offense and any property traceable to it. Bank accounts, vehicles, real estate, and other assets tied to the transaction are all in play.
The government can also pursue civil forfeiture separately. That path lets the government sue the property itself, without a criminal conviction, on a preponderance-of-the-evidence standard. A claimant can contest the seizure, raise an innocent owner defense, and recover legal fees if they substantially prevail.
The Attorney-Fee Exception
The statute carves out one narrow exception you should know about. Transactions “necessary to preserve a person’s right to representation as guaranteed by the sixth amendment” are excluded from the definition of monetary transaction. A criminal defendant can pay a lawyer with funds that would otherwise be criminally derived, and the lawyer accepting those fees does not commit a section 1957 offense by depositing them. Without this carveout, anyone accused of a financial crime could be effectively blocked from hiring private counsel, because any legal fee over $10,000 from tainted funds would expose both the client and the attorney.
When to Get a Lawyer
If you handle large transactions and have any reason to doubt the source of the funds, talk to counsel before the transaction, not after. The knowledge bar under section 1957 is lower than most people assume. You do not need to know exactly which crime produced the money. You do not need to intend anything illegal. If you knew the funds came from some form of criminal activity and you processed a transaction over $10,000 through a financial institution, you have exposure.
A white-collar defense attorney can assess whether a specific transaction creates risk, build compliance practices that catch problems before they become charges, and attack the government’s proof if charges come. The tracing requirement is often the strongest point of attack: if prosecutors cannot show the specific funds in the transaction were criminally derived rather than legitimate money sitting in the same account, the count fails. In parallel forfeiture proceedings, counsel can contest seizures through administrative claims or in court and raise the innocent owner defense where the facts support it.
