What is a "subpoena"?

A subpoena is indeed a court order compelling an individual to appear in court or produce specific documents, records, or evidence relevant to a legal case. This legal tool is essential in the discovery phase and throughout the trial process, as it allows parties to gather necessary information and testimonies that could affect the outcome of the case.

The function of a subpoena emphasizes its importance in maintaining the integrity of the legal process by ensuring that relevant witnesses and documents are available when needed. Compliance with a subpoena is mandatory, and failing to do so can lead to legal penalties, including the possibility of contempt of court.

The other choices do not accurately describe a subpoena. A divorce finalization is unrelated to subpoenas, as it pertains to the conclusion of marital legal proceedings. Evidence presented in a trial encompasses a broader category than just documents or witness appearances, and a summary of a case's arguments does not reflect the compelling nature of a subpoena within legal proceedings. Each of these alternatives addresses different facets of legal processes but does not capture the specific and imperative role of a subpoena.
