What does a subpoena require?

A subpoena is a legal document that commands an individual to appear and testify as a witness in court. It serves as a tool for enforcing the legal obligation to attend court proceedings and provide testimony relevant to a case. When a person receives a subpoena, they are summoned to provide their account of events or information pertinent to legal matters being litigated. Complying with a subpoena ensures that the judicial process can move forward with necessary evidence and testimonies.

The other options do not accurately describe the primary purpose of a subpoena. While financial documentation or maintaining silence may be relevant in other legal contexts, those are not functions of a subpoena itself. The main intention remains focused on securing witness testimony to uphold the integrity and thoroughness of the judicial process.
