Plain-English Summary
Rule 45(a) spells out what every subpoena must state — the issuing court and county, the case title and civil action number, a command to appear, testify, or produce and permit inspection of specified material, and the text of the subpoena's protection, response, and contempt provisions. It issues from the county where the action is pending, or, for a deposition or production tied to an action pending elsewhere, from the county where the deposition, production, or inspection will happen. The Prothonotary issues a subpoena signed but otherwise blank to the requesting party to fill in, and a Delaware attorney, as an officer of the Court, can issue and sign one directly.
Rule 45(b) lets the sheriff or any non-party at least 18 years old serve a subpoena by delivering a copy to the person named, and requires prior notice of any commanded pre-trial document production or premises inspection to be served on every party under Rule 5(b). Rule 45(c) puts an affirmative duty on the party or attorney issuing the subpoena to avoid imposing undue burden or expense, backed by sanctions that can include lost earnings and attorney's fees. A person commanded only to produce documents doesn't have to appear in person unless also commanded to a deposition, hearing, or trial, and has 14 days after service (or less, if the compliance date is sooner) to serve a written objection; once an objection is served, the requesting party needs a court order to inspect or copy anything covered by it.
The Court must quash or modify a subpoena, on timely motion, if it doesn't allow reasonable time to comply, requires disclosure of privileged or otherwise protected material with no exception or waiver, or subjects a person to undue burden. Trade secrets, confidential commercial information, and an unretained expert's opinions get extra protection: the Court can quash or modify the subpoena, or, where the requesting party shows a substantial need that can't otherwise be met without undue hardship and assures reasonable compensation, order production only on specified conditions.
Rule 45(d) requires documents to be produced as they're kept in the ordinary course of business, or organized and labeled to match the categories in the demand, and requires any privilege or trial-preparation claim to be made expressly with enough description to let the other side contest it. Rule 45(e) treats a failure, without adequate excuse, to obey a subpoena as contempt of court.
