Duces Tecum

take with you, bring to a court hearing (Latin)

A subpoena duces tecum (Latin for "bring with you under penalty of punishment") is a court summons to appear and produce tangible evidence for use at a hearing or trial. In law, a subpoena (literally "under punishment") is a court order requiring a person's appearance, also (in some jurisdictions) called a summons. A subpoena duces tecum is a specific form of subpoena requiring that a person bring certain documents or other evidence to the court. It is similar to subpoena ad testificandum (writ of summons to testify orally) but it includes clauses to bring in hand books, papers, etc. for the court.

Latin: bring with you. Used most frequently for a species of subpoena (as in subpoena duces tecum) which seeks not so much the appearance of a person before a court of law, but the surrender of a thing (eg. a document or some other evidence) by its holder, to the court, to serve as evidence in a trial. - (read more on Duces tecum)
