Part Rules
Source: nycourts.gov Part 2 rules, updated April 20, 2026 | Last verified: August 5, 2026
Justice Maslow presides over IAS Part 2 at the Jay Street courthouse in Brooklyn, not at 360 Adams Street. The courtroom is 15.58. The published rules name Principal Law Clerk Jennafer Mukofsky, Assistant Law Clerk Kristin Hazelton, and Part Clerk Alberta Lyght. The rules are long and specific, and the requirements below are the ones counsel most often trip over.
Contacting the Part
Section A2 directs scheduling and logistical questions to the Part Clerk by email rather than by telephone, and not to chambers. The rules permit a telephone call only within 24 hours of a scheduled appearance. Section A4 prescribes the format of the email subject line, and section A5 lists questions the part will not answer. Read those three sections before you write to anyone in the part.
Hard Copies
Section C3 requires hard copies only where a party’s NYSCEF papers cumulatively exceed 200 pages. When that threshold is crossed, the hard copies must include a list of contents and must be divided into segments no thicker than two inches. The movant’s hard copies are due seven days before the date on which the motion is calendared, and hard copies of opposition and reply must be received by the day those papers are filed on NYSCEF. Papers are mailed to Hon. Aaron D. Maslow, 320 Jay Street, Courtroom 15.58, Brooklyn, NY 11201, and proof of compliance is filed on NYSCEF. Below 200 pages, NYSCEF filing alone is sufficient.
Appearance Form
Section D11 requires two business cards or two completed appearance forms at argument, one for the court and one for the court reporter. The court will not permit counsel to complete an appearance form at counsel table, so fill it out before you leave for the courthouse. A Word version is available from the Part Clerk.
AI Certification
Section C15 requires a certification on all motion submissions stating either that no generative artificial intelligence was used, or that artificial intelligence was used and all generated text, including citations, quotations, and legal analysis, was reviewed for accuracy.
Motions and Argument
Under section D6, all motions are presumptively argued in person. The court may decide a motion on submission, but only after giving at least two days’ notice of that determination, and a party may ask for non-submission by emailing the Part Clerk and the law clerks at least 10 days in advance. Section D7 sets the motion calendar day as Friday, with certain complex motions usually heard on a Thursday. Under section D9, calendars are first called at 9:30 a.m., with a second call if all parties are not present before 10:15 a.m. Section D11 provides that all argued motions are heard on the record.

What to Expect
Judge Maslow’s courtroom moves slowly and operates with strict adherence to rules. This is not a part where informality or shortcuts will be tolerated. The judge expects attorneys to know the applicable procedural rules and to follow them precisely.
Tips
- Know the rules cold. Judge Maslow is very rule-oriented. If the CPLR or local Part Rules specify a procedure, follow it exactly. Deviations, even minor ones, will be noted and may work against you.
- Plan for a long wait. This part is very slow. Do not schedule anything else for the same morning or afternoon.
- Jay Street courthouse, Courtroom 15.58. This part sits at 320 Jay Street, not at 360 Adams Street.
- Be prepared on procedure. Substantive arguments matter, but procedural compliance is the baseline. Come prepared to explain your filing history, compliance with discovery orders, and adherence to deadlines.
- Fill out the appearance form before you leave. Section D11 requires two business cards or two completed appearance forms, and the court will not let counsel complete a form at counsel table.
- Count your pages before you print anything. The hard-copy requirement in section C3 is triggered only when a party’s NYSCEF papers cumulatively exceed 200 pages. Above that line, the movant’s hard copies are due seven days before the calendar date, and opposition and reply hard copies are due the day they are e-filed.
- Include the AI certification. Section C15 requires a certification on every motion submission addressing the use of generative artificial intelligence.
- Email the Part Clerk, do not call. Section A2 routes scheduling and logistics to the Part Clerk by email, and permits a telephone call only within 24 hours of an appearance.
Recent Field Notes (Spring 2026)
- The judge writes and posts the order. On contested motions decided on the record, Judge Maslow often drafts the written order himself and posts it to NYSCEF after the appearance. Counsel should not assume an oral disposition is the final word and should monitor NYSCEF for the written order before treating the matter as decided.
- Interest from date awards on contract collections. On breach of contract motions where damages are clear, the part has issued orders awarding principal plus statutory interest running from a specific accrual date. Build the date of breach into your moving papers so the court can fix interest without holding another conference.
- Late discovery and MDJ filings can be cured at the conference. Counsel who file the required document (a missing MDJ, a stipulation, a supplemental affirmation) shortly before the conference and then report compliance on the record have had matters move forward without sanction. File first, then report.
