What is a Subpoena? 

A subpoena is a document that orders a named individual to personally appear at a trial or hearing to:

2) to produce documents or objects to be used at a trial or hearing as evidence (known as a Subpoena Duces Tecum).


Subpoena Ad Testificandum – Use this subpoena when an individual's testimony at a trial or hearing is needed.
