Home » Federal Criminal Defense » Federal Conspiracy – 18 U.S.C. § 371
Under 18 U.S.C. § 371, it’s a federal crime for two or more people to agree to break a U.S. law or defraud the federal government. The law requires two things: an agreement to commit a federal offense and at least one person taking a clear step (called an overt act) toward completing that plan. The government doesn’t need the crime to be finished to prosecute under this law.
Prosecutors favor this statute because it lets them charge people early. If they can show an agreement and one step toward the crime, that’s enough. It’s used across case types, especially where multiple people are involved or the actual crime is still in planning stages.
18 U.S.C. § 371 refers to a broad range when it comes to how it’s used. This section applies to white collar crimes, drug trafficking, immigration fraud, public corruption, and many others. If there’s any agreement to break a federal law or to defraud a government agency, it can trigger a conspiracy charge.
Conspiracy charges help prosecutors deal with group crime. They allow for early arrests and build pressure on individuals to cooperate with the government. In cases where organized planning is key, conspiracy becomes the main charge.
Even if the main crime doesn’t happen, you can still face charges. That makes conspiracy a powerful tool. As long as there’s proof of agreement and one overt act, prosecutors can move forward.
371 conspiracy is common in white collar fraud and large drug operations. Prosecutors don’t need to tie each person to the end result. They, however, focus on the agreement and the role each person played.
To convict someone, the government must prove there was a mutual plan between at least two people in the conspiracy. That plan doesn’t have to be written or spoken; actions, emails, or repeated conduct can show the existence of an agreement.
An overt act is known to be any step that helps move the plan forward. This might be buying materials, making a payment, or sending a message. The act doesn’t need to be illegal itself, just tied to the goal.
The statute encompasses two key angles: conspiring to break a law and conspiring to defraud the United States. Fraud here means obstructing or interfering with lawful government functions through deceit or dishonest means.
Even if the fraud isn’t committed, managers or CEOs who intend to change the books may still be charged. It is easier to bring several executives under one case when there is a 371 conspiracy involved.
Hackers or online scammers who plan data breaches or phishing attacks may be charged under this law, especially when they coordinate across state or national lines.
Drug rings, trafficking groups, or any operation involving multiple jurisdictions often face 18 U.S.C. § 371 charges when the federal government takes over the investigation.
Penalties under this statute follow federal guidelines. This includes factors like the role of the main accused in the plan, the seriousness of the intended crime to be committed, and whether the crime was completed or not.
A conviction can mean approximately five years in prison, heavy fines, and supervised release after serving time. For related crimes, those penalties can increase.
A felony conspiracy conviction can result in deportation for non-citizens. It can also lead to the loss of professional licenses or make it more challenging to work in regulated industries.
The defense may focus on showing there was no clear agreement or that the accused had no intent to join the conspiracy.
If someone can show that they left the plan and communicated this clearly before the overt act, it can weaken the government’s case.
Messages or behaviour can be misunderstood. A defense may argue that actions had innocent explanations.
Improper wiretaps, unlawful searches, or denied legal counsel can make key evidence inadmissible.
Statements by one accused person may be used against another accused. This can be a challenge if the person didn’t know about or approve of those actions.
Federal prosecutors often rely on people who testify in exchange for lighter sentences. Their motives may be questioned in court.
Being connected to a person involved isn’t proof of guilt. The government must prove that you were an active participant in the agreement.
If you’re being investigated or have received a federal subpoena, speak to an attorney immediately. Early steps can shape the case before charges are even filed.

Yes. The government only needs to prove an agreement and one overt act, not that the crime was finished. We challenge whether intent and agreement were truly established.
Most conspiracy charges have a five-year limit, but prosecutors may claim the conspiracy “continued.” We focus on showing when it ended to limit their reach.
Intent is critical—prosecutors must prove you knowingly joined an unlawful plan. We highlight the lack of knowledge or misunderstanding to weaken their case.
