Which term defines someone who represents themselves in legal proceedings?

The correct term for someone who represents themselves in legal proceedings is "pro se." This term is derived from Latin, meaning "for oneself." Individuals who choose to represent themselves do so without the guidance of an attorney, which can occur in various types of legal matters, including civil cases, small claims, and even some criminal proceedings.

The use of "pro se" emphasizes the individual’s decision to act on their own behalf rather than relying on legal counsel. This self-representation can be driven by diverse reasons, such as financial constraints, a desire for direct involvement, or a belief that they can effectively advocate for themselves.

The other terms refer to different roles within the legal system. A defendant is a person accused of a crime or being sued in a civil action. An amicus curiae refers to a "friend of the court," someone who is not a party to a case but offers information or expertise to assist the court in its decision-making. A plaintiff is the party who initiates a lawsuit by filing a complaint against another party. Thus, while these terms are relevant in legal contexts, they do not capture the essence of self-representation as accurately as "pro se."
