Correction: This Is Trial/IAS Part 27, Not an ADR Part
An earlier version of this page described Judge Reilly as presiding over an ADR/ES Conference Part devoted to settlement. That was wrong. The current published Part Rules on nycourts.gov are captioned "Honorable Margaret C. Reilly, Supreme Court Justice, Trial\IAS Part 27," and the part runs a conventional motion and conference calendar. We corrected the page on August 5, 2026.
Note on the Bench Move
The same nycourts.gov file that now carries the Part 27 rules previously carried Judge Reilly's rules as Nassau County Surrogate. Those Surrogate's Court rules are obsolete for this part, and they differ materially: the Surrogate's rules set motions returnable on Wednesdays at 11:00 a.m. and routed adjournments through the Surrogate's Calendar Department. If you are working from a saved copy of her rules, check the caption before you rely on it.
Motion Practice
Motions are returnable on any business day at 9:30 a.m. The court decides motions on submission, so counsel do not appear on the return date. The published exception is disclosure motions.
Form of Papers
Papers must be e-filed unless the case is a paper case. Every physical paper filed with the court must be single-sided, and the court reserves the right to reject a double-sided filing.
Adjournments
A request to adjourn a motion must be e-filed in NYSCEF and emailed. The court will consider the request on good cause shown and with the consent of all parties, and the requesting party must propose a date certain that all parties have consented to at the time the adjournment is sought. Where consent cannot be obtained, the requesting party may file in NYSCEF and email chambers to request a conference call with the Principal Law Clerk about the adjournment request.
Conferences
Preliminary conferences are conducted on the Lower Level of the courthouse, and counsel must follow the court rules governing them.
Practitioner Intelligence
From attorneys who have appeared before this judge. Last updated: April 2026.
The notes below were collected while this page described the part as an ADR settlement part, and we have not re-verified them against Part 27. Read them as practitioner impressions of settlement conferences, not as a description of the part calendar. The published rules above control, and on a motion return date the court decides on submission.
What to Expect
Judge Reilly is actively engaged in settlement discussions. She understands the business aspects of litigation and works collaboratively with counsel to move cases toward resolution. Be prepared for frank conversations about case value and settlement feasibility.
Tips for Success
- Come prepared to discuss settlement. Judge Reilly takes ADR seriously. Have realistic settlement parameters in mind.
- Bring decision-makers or authority. She expects to negotiate with those who can make binding commitments.
- Be candid about your position. Judge Reilly respects honest assessments of case strengths and weaknesses.
- Understand your damages. Have supporting documentation for damage calculations if discussing monetary resolution.
- If settlement stalls, expect a return date. When a settlement demand has been communicated but opposing counsel cannot reach their client, the court will adjourn to a specific date for a settlement status update. If the matter does not settle at that point, the parties return to discuss discovery.
