How the deadline works

Under CPLR 3123(a), the matters set out in a notice to admit are deemed admitted unless, within 20 days after service, the responding party serves a sworn statement denying the matters or setting forth in detail the reasons it can neither truthfully admit nor deny, or serves objections. Because admission is automatic, this is among the most dangerous New York deadlines to miss.

Service by mail within New York adds 5 days under CPLR 2103(b)(2). A deadline landing on a weekend or court holiday rolls to the next business day.

  • Admission is automatic No motion is required for the matters to be admitted — silence past the deadline is enough.
  • Served by mail? Add 5 days under CPLR 2103(b)(2) by selecting "Service by mail" above.
