New York County Supreme Court, Civil Branch:
The Four-Building Guide to New York County Litigation.

Four Buildings. Know Which One You Need.

The most common avoidable error for out-of-county firms appearing in New York County is misidentifying the courthouse. New York County Supreme Court, Civil Branch operates across four facilities, and not all of them are next to each other.

60 Centre Street (“The Rotunda”). The administrative heart of New York County Supreme Court. Home to the Commercial Division (Uniform Rule 202.70), the General Clerk’s Office (Room 119) for processing motions on notice, the Ex Parte Office (Room 315, 646-386-3125) for OSC and TRO applications, the County Clerk's Office (Room 141B, 646-386-5955), and the Commercial Division Support Office (Room 119A, 646-386-3020). The General Clerk's Office number is 646-386-3030. If your matter involves commercial litigation, document filing, or emergency applications, this is where you need to be. Note that the Commercial Division is not confined to this building; Part 55 sits at 71 Thomas Street.

80 Centre Street. Connected to 60 Centre via Worth Street. This is the engine room of discovery. The DCM Courtroom is Room 103, and the Differentiated Case Management programs run the discovery lifecycle for City tort cases and Motor Vehicle cases out of that room. The City and Transit Parts (Part 21 and Part 62) and the Motor Vehicle Part (Part 22) also sit in this building. If your appearance is a compliance conference, preliminary conference, or discovery dispute, check whether it is in this building.

111 Centre Street. Houses general IAS parts. Part 30 (Justice Grieco) and Part 47 (Justice Katsanos) sit here, and both are general IAS parts rather than specialized benches.

71 Thomas Street. Located approximately a five-minute walk from the Foley Square courthouses, 71 Thomas Street houses a substantial share of the bench, and not only general IAS parts. The current listing places Part 56, the Medical Malpractice IAS Part before Justice Kelley, here, along with Part 55 of the Commercial Division before Justice D'Auguste, Part 36 Complex Litigation before Justice Saunders, Part 27 Guardianship before Justice Ramirez, and the general IAS Parts 18, 46, and 58. This is NOT in the Centre Street complex. If your appearance is at 71 Thomas Street, do not go to 60, 80, or 111 Centre Street first. Because of the distance, stacking a 71 Thomas Street appearance with a Centre Street appearance on the same morning requires careful timing. Let us know if you have multiple New York County appearances on the same day so we can plan accordingly.

The Judges You Need to Know.

Part assignments in New York County change, and the individual part rules govern. The assignments below are taken from the Judicial Assignments and Locations listing published by New York County Supreme Court, Civil Term. We read the assigned justice’s current part rules before every appearance, because the requirements differ part by part.

80 Centre Street

Hon. Christopher Chin, Part 22, Courtroom Room 136. Motor Vehicle IAS Part. Courtroom 646-386-3271.

Hon. Richard Tsai, Part 21, Courtroom Room 280. City and Transit IAS Part. Courtroom 646-386-3738.

Hon. Ariel D. Chesler, Part 62, Courtroom Room 328. City and Transit IAS Part. Courtroom 646-386-3274.

111 Centre Street

Hon. John C. Katsanos, Part 47, Courtroom Room 1021. General IAS Part. Courtroom 646-386-3743. Part 47 uses its own preliminary conference, compliance conference, and status conference order forms, together with a stipulation form and a case assignment and scheduling notice, all posted with the part listing. The Part 47 Rules themselves are marked "Forthcoming" on the court's listing, so there is no published rule set for this part yet. Work from the posted forms and the Case Assignment and Scheduling Notice.

Hon. Matthew V. Grieco, Part 30, Courtroom Room 623. General IAS Part. Courtroom 646-386-3275.

60 Centre Street (Commercial Division)

Hon. Joel M. Cohen, Part 3, Courtroom Room 208. Commercial Division. Courtroom 646-386-3287. The part rules were revised June 2, 2026, and the preliminary conference order was revised December 22, 2025, so check the posted version before you draft anything for this part.

Hon. Andrew Borrok, Part 53, Courtroom Room 238. Commercial Division. Courtroom 646-386-3304.

Hon. Melissa Crane, Part 60, Courtroom Room 248. Commercial Division. Courtroom 646-386-3310.

The Discovery Engine. Know the Protocol.

The Differentiated Case Management programs handle the discovery phase for City tort cases and for Motor Vehicle cases in New York County. The procedures there are different from a typical IAS part or a Brooklyn CCP appearance. The DCM Courtroom is Room 103 at 80 Centre Street, 646-386-3683. The City Case DCM Program is reachable at 646-386-3687 and the Motor Vehicle DCM Program at 646-386-3682.

Two points decide most DCM outcomes. Conferences are held before the Law Secretary of the assigned Justice or a specially designated Court Attorney, and a problem that cannot be resolved there is referred to the assigned Justice. If a party is aggrieved by another party’s failure to meet a Case Scheduling Order deadline, that party must inform the DCM Program of the dispute promptly, before the deadline in question and before making a motion.

For the full DCM protocol, see our dedicated guide: Mastering the DCM Matrix: 80 Centre Street Protocols.

Rule 202.70 and the Commercial Division Playbook.

The Commercial Division at 60 Centre Street operates under its own set of rules (Uniform Rule 202.70) that are distinct from general IAS practice. Filing requirements, motion practice, and conference protocols all differ from standard Supreme Court procedure. The Manhattan threshold is $500,000.

For a detailed breakdown of Commercial Division practice, see: The Commercial Division Playbook: Rule 202.70 Strategy. For the substantive causes of action that typically travel through the Commercial Division, see: Business Disputes Overview, Breach of Contract, Partnership and LLC Disputes, and Shareholder Disputes.
