Find Suffolk County Supreme Court Records

Suffolk County Supreme Court Overview

New York uses the name Supreme Court for its main trial court of general jurisdiction, not its highest court. In Suffolk, the Supreme Court hears the biggest civil matters: high-dollar suits, foreclosure, Article 78 proceedings, matrimonial cases, and guardianships. The top state court is the Court of Appeals, and appeals from Suffolk trial courts go to the Appellate Division, Second Department.

Suffolk sits in the 10th Judicial District with Nassau County. Matrimonial and guardianship proceedings take place predominantly in Central Islip, while other civil matters are heard in Riverhead. To search Supreme Court cases, use WebCivil Supreme, covered on the court records page.

The naming trips up many people, so it is worth stressing. In New York, a case being in the Supreme Court does not mean it reached the top of the system. It means the case is in the main trial court. The actual high court, the Court of Appeals, hears only a small set of cases at the end of the line. For most Suffolk residents, Supreme Court is where a serious civil case begins.

Where the Suffolk Supreme Court Sits

The court runs from two main campuses. In Riverhead, the Hon. Alan D. Oshrin Supreme Court Building at 1 Court Street handles non-matrimonial civil matters, and the broader court campus along Center Drive includes the Arthur M. Cromarty Criminal Court Complex. In Central Islip, the Hon. Marquette L. Floyd Supreme Court Building at 400 Carleton Avenue handles matrimonial and guardianship work.

County Court, District Court, and the Lower Courts

Several courts sit below the Supreme Court, and each has a clear job. County Court runs felony criminal trials and limited civil cases up to $25,000. It also hears Extreme Risk Protection Order applications. District Court is the local civil and criminal court, but only in the five western towns.

Family Court hears child and family cases at locations in Riverhead and Central Islip. Surrogate's Court handles estates and wills. In the eastern towns, town and village justice courts handle local civil, criminal, and traffic matters, since District Court does not reach them. This east-west split is unusual and is the key to finding the right Suffolk court.

That split is the single most useful fact for a Suffolk court search. If your matter sits in Babylon, Brookhaven, Huntington, Islip, or Smithtown, the District Court likely applies. If it sits in an eastern town like Southampton, East Hampton, Riverhead, Shelter Island, or Southold, a town or village justice court may apply instead. The County Court and Surrogate's Court, by contrast, serve the whole county from Riverhead.

Supreme Court Versus County and District Court

The three trial courts handle different cases. Knowing the split tells you where a case lives. The comparison below lays it out.

How a Case Moves Through the System

A case can climb the ladder of courts as it proceeds. The path depends on whether it is civil or criminal and where it starts. The flow below shows the usual route for an appeal.

Case flow: Town/Village or District Court › County Court › Supreme Court › Appellate Division, Second Department › New York Court of Appeals

A felony, for example, may begin with a District Court arraignment, move to County Court for trial, and reach the Appellate Division on appeal. A major civil case starts in Supreme Court and appeals the same way. Not every case touches every rung, but the order holds.

The Six District Court Districts

District Court in Suffolk is split into six districts. The First District covers all five western towns and holds the central criminal term in Central Islip, where arraignments run every day of the year in Courtroom D-11. Districts 2 through 6 each cover one town: Babylon, Huntington, Smithtown, Islip, and Brookhaven.

Outlying civil locations keep narrower money windows than their public windows, so check hours before a payment visit.

District Court History Since 1964

The District Court has a specific origin. It became operational in January 1964. Before that, the five western towns each ran their own justice courts, like the eastern towns still do. The Uniform District Court Act transferred that authority to the new court and built a courthouse in each district plus a central First District location.

The central building moved into the Cohalan Court Complex in Central Islip in 1993, and the First District Civil Division opened in Ronkonkoma in 1998. The Uniform District Court Act still supplies the court's authority and fee provisions.

Fees and Forms

District Court publishes its own fee and form pages. Fees cover civil filings, small claims, and copies, separate from the County Clerk schedule. Small claims let individuals 18 or older sue for money up to $5,000, and the court notifies the defendant. Commercial small claims have a five-per-month statewide limit.

The District Court fee page lists the civil and copy fees.

Federal Court in Central Islip

Suffolk is also home to a major federal court. The county sits in the U.S. District Court for the Eastern District of New York, which covers Brooklyn, Queens, Staten Island, Nassau, and Suffolk. The Central Islip courthouse, the Alfonse M. D'Amato U.S. Courthouse, houses the District Court, Bankruptcy Court, and several federal offices.

This is a state-versus-federal distinction worth keeping straight. Suffolk's District Court is a state local court and is unrelated to the federal U.S. District Court. Federal cases and dockets live in PACER, not the state portals.

The Central Islip federal courthouse is also a local landmark. The court page describes it as the second largest courthouse in the country and the largest structure on Long Island. It houses the District Court, the Bankruptcy Court, pretrial services, probation, the U.S. Marshal, and U.S. Attorney offices, along with several state court offices, all under one roof.
