Discovery and evidence

Subpoena

A subpoena is a court-backed command to appear and testify or to produce documents, and it can reach people who are not parties to the case.

A subpoena to testify brings a witness to a deposition, hearing, or trial. A subpoena duces tecum demands records, which is how banks, employers, and phone companies end up in litigation they have nothing to do with.

Recipients are not powerless. They can object, negotiate scope, or move to quash a subpoena that is unduly burdensome, seeks privileged material, or requires travel beyond the geographic limits of the rule.

Non-party subpoenas frequently produce their own mini-litigation, sometimes in a different court where the recipient is located. That is why records disputes involving a bank or a phone carrier can appear on a docket in a district with no other connection to the case.
