Iowa District Courts by County: Jurisdiction and Locations
Iowa's district courts form the foundation of the state's trial court system, handling the overwhelming majority of civil, criminal, family, and probate matters that enter the Iowa judiciary each year. The state is organized into eight judicial districts, each encompassing a defined group of counties, with court locations and jurisdictional boundaries established under Iowa Code Chapter 602. This reference covers how those districts are structured, where courts sit, what case types fall within their authority, and where the limits of district court jurisdiction begin and end.
Definition and scope
Iowa's district courts are general-jurisdiction trial courts established under Iowa Code § 602.6101, which vests in them original jurisdiction over all civil and criminal cases not exclusively assigned elsewhere. The Iowa Judicial Branch administers 99 counties across eight judicial election districts, each of which contains at least one county seat courthouse and, in larger counties, additional courthouse facilities.
The eight districts are:
- First Judicial District — Black Hawk, Bremer, Buchanan, Chickasaw, Fayette, Grundy, and Howard counties (seat: Waterloo/Cedar Falls)
- Second Judicial District — Boone, Calhoun, Carroll, Greene, Hamilton, Hardin, Marshall, Pocahontas, Story, Webster, and Wright counties (seat: Boone/Nevada/Marshalltown)
- Third Judicial District — Buena Vista, Cherokee, Clay, Crawford, Dickinson, Ida, Lyon, Monona, O'Brien, Osceola, Plymouth, Sac, Sioux, and Woodbury counties (seat: Sioux City)
- Fourth Judicial District — Audubon, Cass, Fremont, Harrison, Mills, Montgomery, Page, Pottawattamie, and Shelby counties (seat: Council Bluffs)
- Fifth Judicial District — Adair, Adams, Clarke, Dallas, Decatur, Guthrie, Jasper, Lucas, Madison, Mahaska, Marion, Monroe, Polk, Ringgold, Union, Warren, and Wayne counties (seat: Des Moines)
- Sixth Judicial District — Benton, Iowa, Johnson, Jones, Linn, and Tama counties (seat: Iowa City/Cedar Rapids)
- Seventh Judicial District — Cedar, Clinton, Jackson, Muscatine, and Scott counties (seat: Davenport)
- Eighth Judicial District — Appanoose, Davis, Des Moines, Henry, Jefferson, Keokuk, Lee, Louisa, Mahaska [shared with Fifth], Van Buren, and Wapello counties (seat: Ottumwa/Burlington)
County assignments and courthouse locations are maintained by the Iowa Judicial Branch. District judges, district associate judges, and magistrates operate within these boundaries, with judicial elections organized at the district level under the Iowa merit selection system.

How it works
District courts accept filings at the county courthouse serving each county within a district. Under Iowa Rule of Civil Procedure 1.801, venue in civil cases is generally proper in the county where the defendant resides or where the cause of action arose. Criminal charges are filed in the county where the alleged offense occurred, consistent with Iowa Code § 803.1.
Case processing follows distinct procedural tracks depending on matter type:
- Civil cases (small claims excluded): Filed with the district court clerk; service of process required on all defendants; pretrial scheduling controlled by district court rules issued under Iowa Court Rule 1.900 series.
- Criminal cases: Initiated by trial information or indictment; initial appearance before a magistrate; arraignment and pretrial conference before a district or district associate judge.
- Family law matters: Governed by Iowa Code Chapter 598 for dissolution of marriage; Chapter 232 governs juvenile and child-in-need-of-assistance proceedings in specialized divisions.
- Probate and estate matters: Filed in the county where the decedent was domiciled, under Iowa Code Chapter 633A.
Electronic filing is administered through the Iowa Electronic Document Management System (EDMS), which became mandatory for attorney filers across all districts. Court records subject to public access are governed by Iowa Court Rule Chapter 16.
Common scenarios
District courts encounter a defined set of recurring matter categories that account for the bulk of annual filings across all eight districts:
Civil litigation: Contract disputes, personal injury claims, and property actions make up the core civil docket. Cases with amounts in controversy above $6,500 fall outside small claims jurisdiction and proceed on the standard civil track — see Iowa Small Claims Court for the lower-value alternative.
Criminal prosecution: Felony and serious misdemeanor cases are tried in district court. Class A felonies — which carry mandatory life sentences under Iowa Code § 902.1 — are heard exclusively at the district court level and cannot be resolved by magistrate.
Dissolution of marriage and custody: Iowa's no-fault dissolution framework under Iowa Code Chapter 598 requires district court approval of all final decrees. Contested custody matters often involve guardian ad litem appointments. Further framework detail appears at Iowa Family Law Legal Framework.
Landlord-tenant disputes: Forcible entry and detainer actions, governed by Iowa Code Chapter 648, originate in district court, with magistrates authorized to hear the initial proceedings. See also Iowa Landlord-Tenant Law.
Probate proceedings: Estate administration, guardianships, and conservatorships proceed through the probate division of the district court in the county of domicile. Iowa Code Chapter 633A, the Iowa Trust Code, governs trust-related proceedings in the same venue.
Decision boundaries
District court jurisdiction is broad but not unlimited. Several categories of matters fall outside district court authority or require alternative forums:
- Federal subject-matter jurisdiction: Claims arising under federal statutes, constitutional violations against federal actors, or matters between citizens of different states exceeding $75,000 in controversy (28 U.S.C. § 1332) belong in the U.S. District Courts for the Northern or Southern Districts of Iowa — not Iowa district courts. See Federal Courts in Iowa for that distinction.
- Administrative agency decisions: Initial review of Iowa state agency actions proceeds through administrative hearing processes under Iowa Code Chapter 17A before any district court review. Iowa Administrative Law and Agencies addresses that pathway.
- Tribal jurisdiction: Matters arising on federally recognized tribal lands in Iowa — including the Meskwaki Settlement — may fall under concurrent or exclusive tribal court jurisdiction. Iowa Tribal Law and Federal Jurisdiction covers those boundaries.
- Small claims ceiling: District court magistrates handle small claims only up to $6,500 in controversy (Iowa Code § 631.1). Claims above that threshold must proceed on the standard civil docket.
- Appellate review: District court judgments are appealed to the Iowa Court of Appeals or, in cases transferred by that court or accepted on certiorari, directly to the Iowa Supreme Court. District courts do not review their own final judgments through internal appeal; post-trial motions under Iowa Rule of Civil Procedure 1.904 are the correct mechanism for reconsideration.
Scope and coverage limitations: This page covers Iowa state district courts operating under Iowa Code Chapter 602 and Iowa Court Rules. It does not address federal district court proceedings, municipal infraction hearings held before city officials, or matters governed exclusively by federal administrative agencies. Iowa tribal courts, though operating within the geographic state, operate under separate sovereign authority and are not part of the Iowa Judicial Branch structure addressed here. Readers researching the broader Iowa Legal System should confirm which forum — state, federal, or tribal — has jurisdiction over a specific matter before initiating filings.
