What Is A Subpoena?

In U.S. Law, “subpoena” from the Latin term meaning “under penalty,” is a written document and command from the courts requiring a person to take a certain action like appearing as a witness or handing over a piece of evidence.

There are two primary types of subpoenas:

subpoena ad testificandum (pronounced “ad test-tee-fee-kan-doom”)

This is a written request for an individual to appear in court, via phone, or video to testify about specific claims or events.

subpoena duces tecum (pronounced “doo-seez tay-koom”)

This is a written demand for a person to produce physical evidence such as documents, photos, or videos.

Subpoenas are typically delivered by a process server, sheriff, or bailiff. As the Latin phrase “under penalty” suggests, failing to respond to a subpoena within the designated timeframe can lead to fines or even imprisonment.

A subpoena originates in the courtroom, drafted by a clerk, lawyer, or authorized court officer. It is then served to the relevant individuals, often through a sheriff to ensure its official delivery. Upon receipt, the recipient must act promptly or face legal consequences. The purpose of a subpoena is to obtain crucial information for a case that may not be accessible through a simple request.
