Served 123 LLC handles end-to-end subpoena domestication throughout Maryland under the UIDDA — Md. Code, Cts. & Jud. Proc. §§ 9-401 through 9-407, effective October 1, 2008 — filing with the clerk of the Circuit Court in the county where discovery is sought, across all 24 Maryland jurisdictions (23 counties plus Baltimore City). Every submission includes the Md. Rule 2-510.1 jurisdictional undertaking required since 2017 — the trap that most frequently causes out-of-state UIDDA submissions to be rejected by Maryland clerks.
Since April 2017, Maryland has required both the foreign party AND its attorney to execute a written jurisdictional undertaking as part of every UIDDA submission. Circuit Court clerks — especially Baltimore City and Montgomery — routinely reject submissions that lack the undertaking. Most UIDDA guides miss this rule.
Effective April 1, 2017, Maryland added Md. Rule 2-510.1 — a procedural layer on top of the UIDDA that is unique among UIDDA states. Rule 2-510.1(c) requires that both the foreign party seeking discovery and its attorney execute and file a written "undertaking" by which they submit to the jurisdiction of the Maryland Circuit Court for the limited purpose of complying with Maryland subpoena procedure and resolving any related motions (to quash, for protective order, for enforcement, for contempt, etc.). The form is available through the Maryland Electronic Courts (MDEC) system. Maryland Circuit Court clerks — Baltimore City and Montgomery County especially — routinely reject UIDDA submissions that lack the undertaking, causing out-of-state counsel to restart the clock. Served 123 LLC prepares the Rule 2-510.1 undertaking as part of every Maryland submission packet and routes it for attorney execution before filing. This single step is the difference between a 2-day turnaround and a 2-week restart.
Maryland operates Maryland Electronic Courts (MDEC), the state's statewide electronic filing and case management system, now covering Circuit Courts in all 24 Maryland jurisdictions. UIDDA submissions — including the Rule 2-510.1 undertaking — route through MDEC, enabling next-business-day issuance in most jurisdictions and removing the need for in-person clerk visits. Filing fees are confirmed at intake and advanced as part of every order. Served 123 LLC is registered on MDEC and files electronically as the default path on every Maryland order.
Maryland adopted the Uniform Interstate Depositions and Discovery Act effective October 1, 2008, codified at Md. Code, Cts. & Jud. Proc. §§ 9-401 through 9-407. Under § 9-402, a party submits a foreign subpoena to the clerk of the Circuit Court in the Maryland county (or Baltimore City) where discovery is sought. The clerk is directed to promptly issue a Maryland subpoena upon receipt, incorporating the terms of the foreign subpoena and containing the names, addresses, and telephone numbers of all counsel of record and unrepresented parties.
Maryland has 24 total jurisdictions — 23 counties plus Baltimore City, which functions as a county-equivalent with its own Circuit Court. Each jurisdiction has one Circuit Court with an elected clerk. The proper venue for UIDDA filing is the county where discovery is to be conducted — for depositions, where the witness resides, is employed, or regularly transacts business; for document production or premises inspection, where the documents or premises are located.
Beyond the UIDDA statute itself, Maryland adds two distinctive procedural layers. First, Md. Rule 2-510.1 (effective April 1, 2017) requires both the foreign party and its attorney to execute a written jurisdictional undertaking — this is Maryland's most commonly missed procedural trap. Second, subpoenas seeking medical records are subject to additional requirements under Md. Code Ann., Health-Gen. §§ 4-306 and 4-307 — mental health records require a court order, and medical records generally require patient notice and an opportunity to object. Served 123 LLC handles both layers at intake.
