Served 123 LLC handles end-to-end subpoena domestication throughout Illinois under the Uniform Interstate Depositions and Discovery Act — 735 ILCS 35/1 et seq., effective 2015 — including form preparation, Circuit Court filing across all 102 counties, and service per Illinois Supreme Court Rules 204 and 237. Cook County Law Division requires mandatory eFiling with specific court forms and a $388 filing fee. No local Illinois counsel required.
Under 735 ILCS 35/3(c), the Illinois subpoena must have identical case names, captions, addresses, and telephone numbers of all parties and attorneys — and must name the same document custodian with the same terms and substance of requested material as the foreign subpoena. Any discrepancy can result in the subpoena being rejected or quashed.
Cook County's Circuit Court Law Division requires mandatory eFiling of three specific court forms combined into a single PDF: the Civil Action Cover Sheet (CCL 0520), the Subpoena for a Foreign Action Cover Sheet (CCL 0015), and the Illinois Subpoena in A Civil Matter (CCG N106). The case type is "Petitions to Issue Subpoena – Other Actions," the filing creates a new Illinois case number, and the filing fee is approximately $388 as of 2024. Out-of-state attorneys use Cook County Attorney Code 99500. These requirements are specific to Cook County's Law Division and differ from downstate county procedures — Served 123 LLC handles both.
Under 735 ILCS 35/3.5, if your subpoena seeks documents or information related to lawful health care activity (as defined in the Lawful Health Care Activity Act) or is related to enforcing another state's law that would interfere with rights under Illinois's Reproductive Health Act, you must include a sworn attestation signed under penalty of perjury confirming that an applicable exemption applies. The clerk cannot issue the subpoena without this attestation for qualifying matters. A false attestation carries a $10,000 per-violation statutory penalty, and submission subjects the attestor to Illinois court jurisdiction. This requirement is unique to Illinois and is separate from the DC § 13-449 requirement.
Illinois adopted the Uniform Interstate Depositions and Discovery Act (UIDDA), codified at 735 ILCS 35/1 et seq., effective July 20, 2015. The act allows out-of-state attorneys to submit a foreign subpoena to the Clerk of the Circuit Court in the Illinois county where discovery is sought. Illinois's UIDDA implementation has important procedural nuances — particularly in Cook County — that set it apart from most other UIDDA states.
The Illinois subpoena form must be identical to the foreign subpoena: same case names, captions, attorney contact information, document custodian, and substance of requested material. It must also list all counsel of record and unrepresented parties per 735 ILCS 35/3(c). Any discrepancy between the Illinois and foreign subpoenas is a basis for rejection or a motion to quash.
Once issued, service must comply with Illinois Supreme Court Rules 204 and 237 and 735 ILCS 5/2-1101. Service may be made by certified mail or by a licensed Illinois process server. A critical geographic limit: an Illinois UIDDA subpoena may not require compliance outside the deponent's county of residence in Illinois. This means the subpoena must be filed and served in the county where the recipient lives — with 102 counties statewide, getting this right matters.
