Which document is primarily used to command an individual to appear before the court?

The primary document used to command an individual to appear before the court is a subpoena. A subpoena is a legal order issued by the court that compels a person to attend a legal proceeding, such as a trial or hearing, and may also require them to produce evidence or documents requested by the court.

A subpoena serves as a fundamental tool in the judicial process, ensuring that necessary witnesses or evidence are available to facilitate a fair trial. It ensures that individuals who possess relevant information are required to testify, thereby contributing to the justice system's integrity.

In contrast, a warrant of arrest is specifically used to authorize law enforcement to take a person into custody, not to compel their appearance in court. An affidavit is a written statement of facts confirmed by oath or affirmation, primarily used as evidence rather than a command to appear. A complaint initiates legal action by outlining the plaintiff's grievances but does not directly summon individuals to court.
