Served 123 LLC domesticates and serves out-of-state subpoenas across every Connecticut judicial district under the Connecticut Interstate Depositions and Discovery Act (Conn. Gen. Stat. §§ 52-655 to 660). Connecticut requires a licensed attorney to bring the application — so we file it through our in-house Connecticut counsel, prepare the JD-CL-166 and JD-CL-167 forms, and serve by state marshal.
Connecticut is not a hand-it-to-the-clerk state. CIDDA is a Superior Court action that a licensed Connecticut attorney must file — an appearance plus the JD-CL-166 and JD-CL-167 forms, e-filed under a new docket. Connecticut also bars standalone document subpoenas, so records must ride with a deposition subpoena. We clear both: our in-house Connecticut counsel files it, and a state marshal serves it.

To domesticate a subpoena in Connecticut you do not simply file it with a clerk — the Connecticut Interstate Depositions and Discovery Act (CIDDA) makes it a Superior Court action. A licensed Connecticut attorney files an Appearance with an Application for Issuance of Foreign Subpoena (JD-CL-166) and a Proposed Foreign Subpoena (JD-CL-167) in the judicial district where the witness lives or works, pays the $100 fee, and the clerk issues a Connecticut subpoena under Conn. Gen. Stat. § 52-657. It is then served by a Connecticut state marshal. Served 123 LLC files it through in-house Connecticut counsel, so you do not need your own. Connecticut has worked this way since the CIDDA took effect on July 1, 2023.
Connecticut was one of the last states to modernize interstate discovery. On July 1, 2023, the Connecticut Interstate Depositions and Discovery Act (CIDDA) took effect — Conn. Gen. Stat. §§ 52-655 to 52-660 (P.A. 22-26) — replacing the old regime that required a commission from the out-of-state court, Connecticut local counsel, and a showing that the discovery was material. CIDDA covers both civil and probate actions and lets an out-of-state litigant reach a Connecticut witness for testimony, documents, or a premises inspection.
But Connecticut did not adopt the simple hand-it-to-the-clerk model. Under § 52-657, domestication is a miscellaneous Superior Court action: an Appearance, an Application for Issuance of Foreign Subpoena (JD-CL-166), and a Proposed Foreign Subpoena (JD-CL-167) are e-filed in the judicial district where the witness is located, under a new docket. And the Judicial Branch requires that a licensed Connecticut attorney bring the action for any represented party (Conn. Gen. Stat. § 51-88; Practice Book § 2-44A). Served 123 LLC clears that hurdle for you: our in-house Connecticut counsel files the application, and a Connecticut state marshal serves the issued subpoena.
From intake to the marshal's return — exactly what happens on every Connecticut order.
Use the order form above or email info@served123.com. Include the originating state, the Connecticut judicial district where the witness lives or works, and your subpoena as a PDF. We confirm the matter qualifies under §§ 52-655 to 660 and check that any records demand is paired with a deposition subpoena, as Connecticut requires.
We prepare the Application for Issuance of Foreign Subpoena (JD-CL-166) and the Proposed Foreign Subpoena (JD-CL-167), listing the applicant as plaintiff and the recipient as defendant, attaching your original out-of-state subpoena, and setting a compliance date within 60 days as § 52-657 requires.
Our in-house Connecticut counsel e-files an Appearance with the application in the Superior Court for the correct judicial district, opening a new miscellaneous case, and advances the $100 filing fee (§ 52-259). The clerk then issues the Connecticut subpoena under § 52-657(b). The request is not an appearance in the underlying matter.
Under § 52-658, the issued subpoena is served by a Connecticut state marshal (consistent with § 52-148e), within Connecticut. We dispatch through our marshal network statewide and keep the 60-day compliance window in view. Witness fees are paid to the witness on the day of appearance under § 52-260.
You receive the marshal’s signed return of service confirming completion under Connecticut law — ready for your home-state file. Any motion to quash, modify, or enforce is handled in the Connecticut action under § 52-659.
Most states let a clerk reissue your subpoena over the counter. Connecticut does not. The CIDDA is a Superior Court action that a licensed Connecticut attorney must file on behalf of any represented party (Conn. Gen. Stat. § 51-88; Practice Book § 2-44A). Out-of-state firms usually have to find and retain Connecticut counsel just to get the subpoena issued. With Served 123 LLC, you don’t — our in-house Connecticut counsel brings the action.
We open a miscellaneous Superior Court action in the judicial district where the witness lives or works, e-filing an Appearance (JD-CL-12), the Application for Issuance of Foreign Subpoena (JD-CL-166), and the Proposed Foreign Subpoena (JD-CL-167) with your original out-of-state subpoena. The court opens a new docket and the clerk issues the Connecticut subpoena. The request does not constitute an appearance, so you are not submitting to Connecticut jurisdiction.
Appearance + JD-CL-166 + JD-CL-167 → issued subpoenaBecause the Judicial Branch requires a licensed Connecticut attorney to bring the action for a represented party, most vendors quietly leave that to you — or get it wrong. Served 123 LLC files the application through in-house Connecticut counsel and advances the $100 statutory fee (§ 52-259), so an out-of-state firm clears the one real hurdle CIDDA leaves without retaining its own Connecticut lawyer.
In-house CT counsel · $100 filedConnecticut does not allow a pure records subpoena. Under Practice Book § 13-28(c), a document demand must accompany a deposition subpoena — the witness appears and produces. The proposed subpoena’s compliance date must also fall within 60 days of issuance. We draft the subpoena correctly so it isn’t rejected or rendered unenforceable.
Before July 2023, reaching a Connecticut witness for an out-of-state case was a genuine ordeal. The CIDDA streamlined the substance — though Connecticut still routes it through a court action and a Connecticut attorney.
