St. Louis City Courts and Judicial System

The judicial system serving the City of St. Louis operates through a layered structure of courts with distinct jurisdictions, procedures, and governing authorities. This page covers the composition of those courts, how cases move through the system, the types of matters each court handles, and the boundaries that separate city court jurisdiction from adjacent county and state systems. Understanding how these institutions interrelate is essential for residents, businesses, and practitioners navigating civil disputes, criminal proceedings, traffic matters, and municipal ordinance violations.

Definition and scope

St. Louis City's court system encompasses two primary institutions: the 22nd Judicial Circuit Court and the St. Louis Municipal Court. These courts operate under Missouri's unified court system, which is administered statewide by the Missouri Supreme Court under Article V of the Missouri Constitution.

The 22nd Judicial Circuit Court is the city's court of general jurisdiction. It handles felony criminal cases, civil litigation, family law matters, probate proceedings, and appeals from the Municipal Court. As one of Missouri's 45 circuit courts, it sits within the state judiciary but serves exclusively the geographic boundaries of the City of St. Louis — not St. Louis County, which maintains its own separate circuit court.

The St. Louis Municipal Court operates as a division of the circuit court structure. Its jurisdiction is limited to violations of city ordinances — including traffic infractions, minor code violations, and misdemeanor-level ordinance offenses — as opposed to state criminal statutes.

Scope and coverage limitations: This page applies to courts physically and jurisdictionally situated within the City of St. Louis, an independent city that has operated separately from St. Louis County since the 1876 separation — detailed further at the St. Louis City-County Separation reference page. Courts in St. Louis County, municipalities such as Clayton, Kirkwood, or Ferguson, or courts in Illinois metro counties are not covered here. Missouri state appellate courts — the Missouri Court of Appeals, Eastern District, and the Missouri Supreme Court — are state institutions and fall outside the scope of municipal court administration.

How it works

Missouri's court system uses a four-tier structure: circuit courts (trial courts of general jurisdiction), courts of appeals (5 districts), and the Supreme Court of Missouri at the top (Missouri Courts, mocts.gov). The City of St. Louis's courts occupy the circuit court tier.

Cases move through the system in a sequence governed by Missouri Supreme Court Rules and local court rules:

1. Case initiation — A charge or civil petition is filed with the Circuit Clerk of the 22nd Circuit. Criminal cases begin by arrest, summons, or information filed by the St. Louis Circuit Attorney's Office. Civil cases begin with plaintiff petition filing.
2. Arraignment or initial appearance — In criminal matters, the defendant appears before a judge for formal charge reading and entry of plea. Bail determinations follow under Missouri's pretrial release statutes (RSMo Chapter 544).
3. Pretrial proceedings — Motions, discovery, and scheduling occur under court supervision. Felony cases may proceed through a grand jury or preliminary hearing.
4. Trial or disposition — Cases are resolved by bench trial, jury trial, guilty plea, or dismissal. The 22nd Circuit maintains specialized divisions including a Drug Court, Family Court, and Probate Division.
5. Sentencing and post-conviction — Felony sentencing follows Missouri sentencing guidelines. Appeals from the 22nd Circuit go to the Missouri Court of Appeals, Eastern District, located in St. Louis.

Municipal Court proceedings are simpler: defendants appear for arraignment on ordinance violations, may pay fines, contest charges before a municipal judge, or appeal adverse rulings to the circuit court within 10 days under Missouri Supreme Court Rule 37.

The St. Louis City Sheriff's Office provides courthouse security and executes court orders, including civil process service and prisoner transport, connecting law enforcement operations directly to the judicial system.

Common scenarios

Residents and businesses encounter St. Louis City courts across a predictable set of situations:

• Traffic and parking violations — Contested traffic citations issued within city limits are adjudicated in Municipal Court. Fines, points, and license suspension matters are resolved here before any circuit court appeal.
• Landlord-tenant disputes — Unlawful detainer (eviction) actions and rent-escrow proceedings fall within the 22nd Circuit's civil division. Missouri's landlord-tenant law under RSMo Chapter 441 governs these proceedings.
• Felony criminal charges — Offenses such as assault, robbery, and drug trafficking are prosecuted in the 22nd Circuit by the Circuit Attorney's Office. Jury pools are drawn from registered voters and licensed drivers within city boundaries.
• Probate and estate matters — Wills, guardianship petitions, and administration of decedents' estates go through the 22nd Circuit's Probate Division, which operates under RSMo Chapter 472.
• Domestic relations — Divorce, child custody, and child support cases are filed in the Family Court division of the 22nd Circuit.
• Municipal ordinance enforcement — Code violations related to property maintenance, nuisance abatement, and business licensing originate with city enforcement agencies and are adjudicated in Municipal Court.

Decision boundaries

The most consequential decision boundary is jurisdiction: whether a matter belongs in St. Louis City courts, St. Louis County courts, or a municipal court in one of St. Louis County's 88 municipalities.

City vs. County jurisdiction turns entirely on where the alleged act or transaction occurred. An offense committed in Creve Coeur or Florissant falls under St. Louis County Circuit Court authority, not the 22nd Circuit. An offense committed within the city limits — regardless of where the defendant resides — belongs in the 22nd Circuit or Municipal Court depending on whether the charge is a state statute violation or a city ordinance violation.

Circuit Court vs. Municipal Court distinction governs the severity threshold. State-law misdemeanors and all felonies belong in circuit court. City ordinance violations — even when they mirror state offenses in substance — are municipal court matters carrying ordinance-level penalties rather than state criminal penalties. This distinction affects whether a conviction appears on a state criminal record.

Venue in civil matters follows Missouri's venue statutes under RSMo Chapter 508. A plaintiff suing a defendant who resides or does business in the city may file in the 22nd Circuit, but multiparty cases or matters involving county-based defendants may require transfer or concurrent filing.
