How to Serve an Out-of-State Subpoena in Missouri

No. As of August 2026, Missouri has not adopted the Uniform Interstate Depositions and Discovery Act. Nationally, the UIDDA has been enacted in 48 states and the District of Columbia; New Hampshire’s enactment (HB 1489, Chapter 172, signed June 19, 2026) takes effect January 1, 2027, leaving Massachusetts and Missouri as the only non-adopting states. In Missouri, foreign subpoenas cannot simply be handed to a clerk for ministerial reissuance.

Missouri’s General Assembly has considered UIDDA repeatedly — SB 1005 (2022), SB 394 (2023), HB 1452 (2024), HB 128 (2025), and in 2026 HB 1711 with companion bills SB 1180 and SB 1386 — all proposing the model act as new RSMo Chapter 510 sections. None became law; the 2026 measures were postponed in committee and died when the legislature adjourned sine die on May 15, 2026. Some legal-industry sources still list Missouri as a UIDDA adopter based on those bills’ proposed effective dates; that is wrong, and filing on that assumption gets the package rejected. Background on the model act is in our Nationwide UIDDA Subpoena Domestication Guide and our UIDDA explainer.

Missouri Supreme Court Rule 57.08. When a deposition is to be taken in Missouri under another state’s laws for use there, the circuit court in the county where the deponent is found may, on ex parte application, order issuance of a subpoena as provided in Rule 57.09.

The application is ex parte — no adversarial hearing is required — but it is a court filing that results in a court order, not a clerk counter transaction. Where a UIDDA clerk will promptly issue on the foreign subpoena alone, the Missouri subpoena packet the party submits includes multiple documents: the ex parte application, the trial state’s authorization for out-of-state discovery (a commission, letters rogatory, or the deposition notice or subpoena your home state’s law provides), a copy of the foreign subpoena, and the proposed Missouri subpoena — best practice is to include the names, addresses, and telephone numbers of all counsel of record as well. Rule 57.08 operates only where the deposition is to be taken “pursuant to the laws of another state,” and once issued, discovery conducted in Missouri must comply with Missouri’s Rules of Civil Procedure — Rule 57 for depositions and Rule 58 for the production of documents and things — so the proposed subpoena should track those rules, not the discovery mechanics of the home jurisdiction. The court may also enter such orders as it could enter if the deposition were for a Missouri case, having due regard for the foreign jurisdiction’s laws and rules. The rule text is published at courts.mo.gov, Rule 57.08. A commission-based path under RSMo Chapter 492 also exists for depositions on commission from the foreign court.

Yes. Because Rule 57.08 requires an application to a Missouri circuit court, and filing in Missouri court is the practice of law, a Missouri-licensed attorney must prepare and file the application. This is the defining operational difference from UIDDA states, where requesting issuance is expressly not an appearance.

This is where non-UIDDA cost and friction concentrate: retaining counsel, preparing the ex parte application, and conforming the proposed Missouri subpoena to Rules 57 and 58 practice. Countrywide Process maintains Missouri attorney relationships and packages the application so out-of-state counsel never has to source, brief, and manage a Missouri lawyer for a single subpoena.

File the ex parte application with the circuit court clerk of the county where the deponent or records custodian resides or is found — Rule 57.08. The two classic venue mistakes are geographic: treating the City of St. Louis and St. Louis County as one jurisdiction, and forgetting that Kansas City spans both Missouri and Kansas.

Common pitfalls — Missouri geography. First: the City of St. Louis and St. Louis County are separate jurisdictions with separate circuit courts — the City is an independent city served by the 22nd Judicial Circuit, while St. Louis County is the 21st Judicial Circuit in Clayton. A packet delivered to the wrong clerk’s office does not get forwarded; it gets returned. Second: the Kansas City metro spans both Missouri and Kansas jurisdictions and state lines. A witness in Kansas City, Missouri may sit in Jackson, Clay, Platte, or Cass County — each its own circuit — while a witness in Kansas City, Kansas (Wyandotte County) is not a Missouri matter at all — that subpoena runs through Kansas procedure instead, and Rule 57.08 has nothing to do with it. Confirming the deponent’s exact address before anything is filed is the cheapest step in the entire process.

Budget three components: the circuit court deposit (set locally — e.g., St. Louis County lists $105.50 for a subpoena to take an out-of-state deposition; Jackson County lists $112.50), Missouri counsel’s fee for the Rule 57.08 application, and the $25.00/day witness fee plus mileage under RSMo § 491.280 at service.

Deposits are set circuit by circuit and change with posted fee schedules; the two figures above come from the circuits’ official published schedules and should be re-confirmed at intake. Missouri’s dollars go less to the court and more to the mandatory attorney layer — the deposit is the small part of the bill.

Obtain the trial-state commission or authorization; engage Missouri counsel; counsel files the ex parte Rule 57.08 application in the circuit court where the deponent is found; the court orders issuance of a Missouri subpoena under Rule 57.09; serve it per Rule 57.09(d) with the $25.00/day witness fee tendered — and at least 10 days before compliance for non-party document subpoenas.

Operational pro-tip — build the counsel step into your discovery calendar. Missouri’s timeline is dominated not by the court but by counsel logistics: sourcing a Missouri attorney, conflicts-checking, and preparing the ex parte application. Attorneys who treat Missouri like a UIDDA state and calendar a few days for “clerk issuance” routinely blow deposition dates. Start the Missouri workstream the moment the witness is identified, and expect the court-order step itself to be the fast part once the application is on file.

How does a Missouri non-party object to a subpoena?

Two protections do most of the work: a non-party document subpoena must be served not fewer than 10 days before the compliance date under Rule 57.09(c), and motions for protective orders, or to quash or modify, are filed in the issuing Missouri circuit court under Rules 56.01(c) and 57.09 — through Missouri counsel.

Missouri’s procedural rules govern all disputes relating to subpoenas issued in Missouri, and enforcement runs the same direction: a subpoena for documents must be served at least ten days before the compliance date under Missouri Rule 57.09(c), and if the witness or custodian fails to comply, the remedy is a motion to compel or enforce filed in the issuing circuit court — not in the trial state’s court, which has no power over the Missouri non-party. Because any of that motion practice is a Missouri court appearance, the Missouri counsel engaged for the initial application typically stays on for the enforcement phase. In day-to-day practice, most compliance failures in Missouri trace to service defects — a missed fee tender under Rule 57.09(d) or a document subpoena served inside the 10-day window — which is why professional service with a documented tender is the cheapest enforcement insurance available.

How does Missouri’s procedure compare with a UIDDA state’s?

In a UIDDA state, a clerk issues the local subpoena ministerially, no local counsel is needed, and turnaround runs days. In Missouri, a circuit judge must order issuance on an ex parte application filed by Missouri-licensed counsel, supported by the trial state’s authorization — more steps, more cost, more calendar.
