A criminal charge of aiding and abetting is known as an accomplice crime, and may be brought against anyone who helps with the commission of a crime. Aiding and abetting charges vary from state to state (and under federal law), but generally require that the defendant knowingly and intentionally aided and abetted the principal(s) in each essential element of the underlying crime. A person charged with aiding and abetting is often not present when the underlying crime is committed, but has knowledge of the crime before the crime is committed, and assists with the commission of the crime by providing information, action, or financial support. If the person aiding and abetting has a sufficient degree of involvement in the crime, the participation may rise to the level of being a conspiracy to commit the underlying crime.

In Nevada, aiding and abetting is addressed under the state's accomplice liability laws. According to Nevada Revised Statutes (NRS), a person can be charged with aiding and abetting if they intentionally help, encourage, or facilitate the commission of a crime. This assistance can be through actions, advice, or financial support. The individual charged with aiding and abetting does not need to be present at the scene of the crime but must have knowledge of the criminal intent and act with the purpose of helping the crime succeed. The charge of aiding and abetting in Nevada carries the same penalties as the principal offense, meaning that an accomplice can face the same consequences as the person who directly committed the crime. Additionally, if the involvement is significant enough, the charge can escalate to conspiracy, which is a separate offense and involves an agreement to commit a crime and an overt act towards its completion.
