When are New York reply affidavits due after a proper demand?

Confirm the original motion was served with the qualified sixteen-day notice and demand. This statutory one-day reply requirement belongs to that branch.

Preserve the actual return date, return time and any separate reply direction. Do not count from service of the opposition papers.

Responsible actor. The party serving reply or responding affidavits in the qualified demand branch. The one-calendar-day reply branch after independently verified sixteen-day notice and demand. Personal service and actual open-day return, without a different order or unsupported method.

1. Confirm the original motion was served with the qualified sixteen-day notice and demand. This statutory one-day reply requirement belongs to that branch.
2. Preserve the actual return date, return time and any separate reply direction. Do not count from service of the opposition papers.
3. Exclude the actual return day and count 1 calendar days backward. Intermediate weekends and public holidays remain in the count. General Construction Law 25-a permits the next succeeding business day for a closed final statutory day.
4. Serve the reply or responding affidavits by the selected statutory boundary and furnish required court papers. A rolled return-day date does not excuse the actual hour or a different order.

General Construction Law 20 excludes the event day. Its closed-intervening-day exception applies to an exact two-day period, not to a one-day period. Intermediate weekends and public holidays count in other calendar-day periods. Section 25-a expressly includes statutory periods before which an act is due and permits the next succeeding business day for a closed final day. Rollover can place a backward boundary on the return date; preserve the stated hour and actual court directions. Roberts, a separately identified uncorrected Supreme Court decision concerning opposition to a cross-motion, applied section 25-a to a Sunday boundary before a Monday return. It is corroboration of that final-day treatment, not a different universal briefing rule.

The independently derived 2026 and 2027 calendar follows General Construction Law 24 and Election Law 8-100. It includes Lincoln’s Birthday, Flag Day on the second Sunday in June, Juneteenth, general election day and the other specified holidays. Section 24 adds the next day when a listed holiday falls on Sunday, except Flag Day. A Saturday holiday is not automatically observed on Friday under this provision. Additional appointed holidays and actual court or system closures require separate proof.

These calculators cover established events and final dates within January 1, 2026 through December 31, 2027. They require the disclosed statutory branch, independently valid service, no unsupported method addition, no different actual court order and no additional closure. Backward presets require an actual open-day return date. Earlier editions, the 2020 executive-order toll and dates beyond the retained calendar require separate review and receive no computed or paid date. This software coverage boundary does not establish that an actual act is late.

Fictitious example

The one-calendar-day reply branch after independently verified sixteen-day notice and demand. Personal service and actual open-day return, without a different order or unsupported method. Fictitious established event on the input date. The one-calendar-day reply branch after independently verified sixteen-day notice and demand. Personal service and actual open-day return, without a different order or unsupported method.

Fictitious established facts. The result does not prove valid service, the required exception, actual filing, preserved jurisdiction or a granted court extension. The applicable hour and actual court directions remain separate checks.

Calendar day, not business day

General Construction Law 20 does not exclude intermediate closed days from a one-day period. Its closed-intervening-day exception is exact two days only.

Closed final statutory day

General Construction Law 25-a permits the next succeeding business day, including statutory backward periods. A rolled date may be the return date. Establish the actual hour and court directions.

Without qualified demand

CPLR 2214(b) does not provide this same fixed one-day reply branch without the qualifying demand. Obtain the actual court or part schedule instead.

Orders to show cause

A show-cause order specifies its own time and manner. Do not substitute this ordinary noticed-motion preset.

• In the applicable Supreme Court NYSCEF program, rule 202.5-b(d)(3)(i) permits transmission day or night and identifies recorded transmission with required fee information or permitted actual later payment as the filing event. Interlocutory service under (f)(2) depends on the transmitted NYSCEF notification reaching the proper participating addresses. Filing initiating papers does not itself establish defendant service. Under (h)(2), the clerk’s entry notification is not party service of notice of entry. Preserve the actual document, proof, timestamp, fee event, recipients and court requirements. Paper filing requires the applicable office procedure and receipt. The qualifying technical-failure and emergency hard-copy branches in (i) and (d)(1)(iii) require their actual conditions and later electronic filing; they are not presumed here.
