Marin County Superior Court

About the Marin County Superior Court

California unified its trial courts in 1998, after voters approved Proposition 220. Before that, the state had separate superior and municipal courts. Now the work is combined in one superior court per county. The Superior Court of California, County of Marin hears criminal, civil, family, juvenile, probate, mental health, traffic, and small claims matters. The court administration page lists 12 superior court judges, one commissioner, and one referee.

That single-court structure is why a District Court page would be the wrong name for California. The trial court here is the Superior Court, and it sits inside the Hall of Justice at the Marin County Civic Center.

One court does not mean one judge. The bench spreads across lettered courtrooms, each assigned to a subject area, with supervising judges over the larger divisions. A commissioner handles child support, and a referee handles traffic and small claims. That structure lets a single court manage everything from a felony trial to a name change without separate courthouses for each type of case.

Marin County Superior Court Judicial Assignments

The court assigns judges to courtrooms by subject matter, and each department has a public phone line. Assignments change over time, so confirm a judge and courtroom before a hearing. The table below reflects the court's published assignments by judge, courtroom, and subject.

Divisions of the Marin County Superior Court

The court is organized into divisions that match the kinds of cases it hears. The Civil Clerk handles disputes over money, property, contracts, and civil rights, classified as limited or unlimited based on the amount at stake. Family Law covers divorce, support, custody, parentage, adoption, and domestic violence. The Criminal Division handles felonies, misdemeanors, and infractions, while Probate handles estates, trusts, guardianships, and conservatorships.

Two more divisions round out the trial work. Traffic handles cases that start with a citation, and the Juvenile Division handles dependency and justice matters that are confidential by law. Small claims sits with the court as well, often on the traffic referee's calendar.

The division split affects where a record lives and who can see it. Civil and probate files are largely open. Juvenile and mental health files are not. Family files are public in part but often limited on sensitive detail. Knowing the division tells you, before you even search, whether a file is likely to be open, restricted, or sealed. That single fact saves people from chasing a record that the law keeps closed.

Filing and Records at the Superior Court

Filing happens at the Civic Center, with most civil, family, and probate work taking place at the Room 113 clerk windows. Documents can be filed in person, by mail, through the drop box, or by electronic filing. A court order now requires electronic filing in non-criminal cases, so civil, family, and probate filers should expect to file online unless an exception applies. New-case filings should arrive before the afternoon cutoff, since documents received after 3:30 p.m. are processed the next court business day.

Records access runs through the same building. The public can search cases and calendars on the court's ePortal, and view public documents at the Room 113 kiosk. For copies and certified documents, the court's records process applies. The full how-to is on the court records page and the Clerk of the Superior Court page. Because divisions share the same clerk windows, the case type you give the clerk decides how the request is handled and which staff pull the file.

How a Marin County Case Moves Through the System

A case starts and usually ends in the Superior Court, but it can move up if a party appeals. The flow below shows the path for most Marin matters.

Case flow: Superior Court of Marin › California Court of Appeal, First Appellate District › Supreme Court of California

Most cases never leave the first step. A trial judgment or order is the end of the road unless someone files an appeal. Certain limited civil, misdemeanor, and infraction appeals are handled within the superior court's own appellate division rather than the Court of Appeal.

Trial Court vs Appellate Courts

The three levels do different jobs, and people often confuse a trial with an appeal. The Superior Court hears evidence and decides cases. The Court of Appeal reviews those decisions for legal error. The Supreme Court takes a smaller set of cases, mostly by its own choice. The comparison below lays out the roles.

Appeals From the Marin County Superior Court

An appeal is not a second trial. It is a review of whether the trial court followed the law. Most appeals from Marin go to the California Court of Appeal, First Appellate District, which covers the Bay Area region. From there, a party can ask the Supreme Court of California to review the decision, but that court takes only a fraction of the petitions it receives.

Some matters skip the Court of Appeal. Limited civil cases, misdemeanors, and infractions are reviewed within the superior court's appellate division. The right path depends on the case type, so the rules and the clerk are the guide before filing.

Specialty Courts in Marin County

The Superior Court runs several problem-solving calendars for people whose cases tie back to addiction, mental health, or military service. Adult Drug Court sits in Courtroom K, and Veteran's Treatment Court in Courtroom M. The court also lists a STAR Court in Courtroom J and a Community Court in Courtroom H.

These programs combine treatment, supervision, and regular check-ins with a judge. The court's published material does not spell out every eligibility rule, so screening usually runs through defense counsel, the Public Defender, the District Attorney, or probation. For the criminal-case side, see the arrest records page.

Marin County Courthouse Address

The court is in the Hall of Justice wing of the Marin County Civic Center, the landmark Frank Lloyd Wright complex in San Rafael. Different tasks happen in different rooms, so the room number matters as much as the street address.

The court's judicial assignments and contact details are kept current on its judicial assignments page and its contact page.

History of the Marin County Superior Court

The court grew up inside the Civic Center, designed by Frank Lloyd Wright. Wright chose to bridge the hills with arches rather than level them, and his foundation finished the work after he died. The Hall of Justice opened in 1969, with circular courtrooms, curved seating, and a central lectern, a clear break from the old square courtroom. The 1998 court unification then folded the municipal court into the superior court, giving the county the single trial court it has today. The underground county jail, added in 1994, connects to the court areas through a tunnel, so the Hall of Justice ties courtrooms, the District Attorney, and custody functions into one wing of the campus.
