Served 123 LLC handles end-to-end subpoena domestication throughout Connecticut under the Connecticut Interstate Depositions and Discovery Act (CIDDA) — C.G.S. §§ 52-655 through 52-660. We provide in-house Connecticut-licensed counsel, handle all e-filing requirements, and coordinate State Marshal service statewide across all 8 judicial districts.
Per C.G.S. § 52-657(c)(2), the Application for Issuance (JD-CL-166) must be signed by the applicant party, not by counsel. Submitting with only counsel's signature is the most common cause of CIDDA rejection. Served 123 LLC coordinates directly with you to ensure the application is executed correctly before filing.
Under C.G.S. § 51-88 and Connecticut Practice Book § 2-44A, a Connecticut-licensed attorney must bring the CIDDA action on behalf of any represented party. Unlike most UIDDA states, you cannot simply file these documents yourself or have out-of-state counsel file directly. Served 123 LLC includes in-house Connecticut-licensed counsel with every order — so you don't need to hire separate local counsel. This is our key differentiator for Connecticut domestications.
Connecticut enacted the Connecticut Interstate Depositions and Discovery Act (CIDDA), codified at C.G.S. §§ 52-655 through 52-660, effective July 1, 2023. CIDDA applies to civil and probate actions pending on or after that date and eliminates the old pre-CIDDA requirement of obtaining a court commission and demonstrating materiality — a major procedural simplification.
Under CIDDA, an out-of-state party files three forms with the Connecticut Superior Court in the judicial district where the subpoena recipient is located: a JD-CL-12 Appearance, a JD-CL-166 Application (signed by the applicant), and a JD-CL-167 Proposed Foreign Subpoena — all submitted via e-filing. The $100 filing fee is paid electronically. The clerk then promptly issues the Connecticut subpoena without judicial involvement.
Once issued, service must be completed by a Connecticut State Marshal, either in-hand or at the recipient's usual place of abode, per C.G.S. § 52-148e. The compliance date specified in JD-CL-167 must be within 60 days of issuance, and recipients may serve a written objection within 15 days of service per C.G.S. § 52-148e(f)(2).
Appearance — filed by CT-licensed counsel on behalf of the applicant.
Application — must be signed by the applicant party, not counsel. Includes affidavit of pending proceeding.
Proposed Foreign Subpoena — incorporates terms of foreign subpoena; compliance date within 60 days of issuance.
From intake to affidavit — Connecticut's CIDDA process under C.G.S. § 52-657, with in-house CT counsel included.
Use the order form at the top of this page or email info@served123.com. Include the originating state, Connecticut judicial district of service (based on where the recipient is located), and your foreign subpoena as a PDF. Note whether you need deposition testimony, document production, or both.
Served 123 LLC's Connecticut-licensed in-house counsel takes over. Per C.G.S. § 51-88 and Practice Book § 2-44A, a CT-licensed attorney must file the CIDDA action for represented parties. Our in-house counsel reviews the matter, determines the correct Superior Court judicial district, and prepares all three required forms.
We coordinate with you to ensure the JD-CL-166 Application is signed by you (the applicant party) as required by C.G.S. § 52-657(c)(2). The affidavit confirms the foreign proceeding is pending and identifies the foreign court, docket number, and case name. Only the applicant or their CT-licensed attorney may sign — out-of-state counsel signing alone causes rejection.
Our CT-licensed counsel electronically files the JD-CL-12 Appearance, JD-CL-166 Application, and JD-CL-167 Proposed Foreign Subpoena with the Connecticut Superior Court via the e-filing system under case type M75 (civil) or F75 (family/probate). The $100 filing fee is paid electronically. A new miscellaneous action docket number is generated by the court.
Per C.G.S. § 52-657(b), the clerk has no discretion to reject a legally compliant submission and must promptly issue the Connecticut subpoena. The issued subpoena incorporates the terms of your foreign subpoena. We retrieve it and provide you a copy immediately upon issuance.
We coordinate a Connecticut State Marshal authorized in the relevant county to serve the subpoena per C.G.S. § 52-148e — either in-hand or by leaving it at the recipient's usual place of abode. The compliance date must be within 60 days of issuance. Recipients have 15 days after service to serve a written objection.
You receive a signed, court-ready affidavit of service confirming full compliance with Connecticut's CIDDA requirements and C.G.S. § 52-148e — ready for immediate filing in your originating state court.
