Served 123 LLC domesticates and serves out-of-state subpoenas across all three Delaware counties under the Uniform Interstate Depositions and Discovery Act (10 Del. C. § 4311). We prepare the Delaware subpoena, file with the Superior Court Prothonotary, and serve under Superior Court Civil Rule 45.
Your out-of-state subpoena is unenforceable in Delaware until the Prothonotary reissues it as a Delaware subpoena. Serve your home-state subpoena directly on a Delaware registered agent or witness and it carries no weight. We get the Delaware subpoena issued first, then serve under Rule 45.

To domesticate a subpoena in Delaware, file your out-of-state subpoena, a completed Delaware “Out of State Subpoena,” and the $75 fee with the Prothonotary of the Superior Court in the county where discovery is sought — New Castle, Kent, or Sussex. Under 10 Del. C. § 4311 the Prothonotary promptly issues the Delaware subpoena; there is no hearing, and the request is not an appearance in Delaware’s courts. Delaware requires no reciprocity. We prepare the state’s official Out of State Subpoena form and handle filing and service end to end.
Delaware adopted the Uniform Interstate Depositions and Discovery Act as 10 Del. C. § 4311, effective July 12, 2010 — a statute, codified in a single section of the Delaware Code. It lets an out-of-state litigant obtain an enforceable Delaware subpoena for depositions, testimony, documents, and inspection of premises, without a new lawsuit, a motion, or a hearing.
Under § 4311(c), you submit the foreign subpoena to the Prothonotary of the Superior Court in the Delaware county where discovery is sought, together with a completed Delaware subpoena and the $75 fee, and the Prothonotary promptly issues the Delaware subpoena. The statute is explicit that the request does not constitute an appearance in Delaware’s courts. Because most U.S. companies are incorporated in Delaware, the majority of these subpoenas seek business records from entities served through their registered agent — work Served 123 LLC manages across all three counties.
From intake to affidavit — exactly what happens on every Delaware order.
Use the order form above or email info@served123.com. Include the originating state, the Delaware county where discovery is sought (New Castle, Kent, or Sussex), and your subpoena as a PDF. We confirm the matter qualifies under § 4311 at intake.
We prepare a completed Delaware Out of State Subpoena (the Superior Court form) that incorporates the discovery commanded in your foreign subpoena and carries the names, addresses, and telephone numbers of all counsel of record and any unrepresented party, exactly as § 4311(c)(3) and the Prothonotary’s filing instructions require.
We file the cover letter, the original and a copy of your foreign subpoena, and the completed Delaware subpoena with the Prothonotary of the Superior Court in the correct county, and pay the $75 fee (advanced and included). Issuance is administrative — no motion, no hearing, no appearance.
The Prothonotary signs and seals the Delaware subpoena and returns it; our authorized representative waits at the counter for issuance and retrieves it in person, then sends you a copy. No court appearance is required.
We dispatch through our licensed Delaware process-server network under Superior Court Civil Rule 45, with up to three diligent attempts per address — including service on a Delaware registered agent when the target is an entity. Statutory witness fees ($2/day plus $0.03/mile round-trip, 10 Del. C. § 8903) are tendered when a witness must appear and quoted in advance.
You receive a signed, court-ready affidavit (Declaration of Server) confirming completion in full compliance with Delaware law — ready for immediate filing in your home-state case.
Before July 2010, reaching a Delaware witness or records custodian for an out-of-state case meant a commission and a court order. The UIDDA replaced that with a single Prothonotary filing.
The complete § 4311 framework, the Superior Court Civil Rule 45 provisions that govern form, service, and objections, and the statute that sets witness fees — the authority we work from on every Delaware order.

A Prothonotary’s refusal to issue, a defective service, or a motion to quash can cost weeks and blow your discovery window. These are the Delaware-specific errors we screen out before anything is filed.
Your home-state subpoena has no force in Delaware until the Prothonotary reissues it. We get the Delaware subpoena issued first.
§ 4311(c)(3) requires the names, addresses, and telephone numbers of all counsel of record and any unrepresented party. We assemble the full set.
The Delaware subpoena must incorporate the discovery actually commanded in the foreign subpoena. We mirror it exactly.
Filed somewhere other than where discovery occurs — New Castle, Kent, or Sussex. We file in the discovery county.
An attendance subpoena requires tendering the 10 Del. C. § 8903 witness and mileage fees with service. We tender them.
The $75 fee must be paid to the Prothonotary Office in the correct county. We advance it and confirm the office.

Every major subpoena type we domesticate in Delaware under § 4311.
Requires a person to produce documents, records, or ESI for inspection and copying. Business-records subpoenas are expressly authorized under § 4311(b)(5).
Requires personal appearance and testimony. Witness and mileage fees ($2 per day plus $0.03 per mile round-trip, 10 Del. C. § 8903) apply.
Requires a witness to appear for a recorded deposition under § 4311 — often combined with document production in a single subpoena.
Directs an entity in Delaware to designate a representative to testify. Because most U.S. corporations are Delaware-incorporated, these are often served on a registered agent; the subpoena can also compel inspection of premises under the entity's control (§ 4311(b)(5)).
