New York discovery sanctions: CPLR 3126's threshold, and why "wilfully" does the work
New York procedure · Last verified August 17, 2026
New York separates compelling disclosure from punishing its absence, and puts a meaningful threshold in front of the second. Understanding where that threshold sits explains most of what happens in a New York discovery dispute.
Compelling a response — CPLR 3124
The whole provision is one sentence:
If a person fails to respond to or comply with any request, notice, interrogatory, demand, question or order under this article, except a notice to admit under section 3123, the party seeking disclosure may move to compel compliance or a response.
Broad coverage — any request, notice, interrogatory, demand, question or order in the disclosure article. One express exclusion: a notice to admit under CPLR 3123, which has its own machinery.
CPLR 3124 sets no deadline for the motion, no meet-and-confer requirement, and no certification. Those come from the Uniform Rules for the trial courts — most notably the requirement of an affirmation of good faith effort to resolve the dispute, which appears in 22 NYCRR § 202.7 rather than in the CPLR. Individual parts add their own conference requirements. Checking the part rules before moving is the practical step the statute doesn't mention.
The sanctions threshold — CPLR 3126
CPLR 3126 opens by defining who it reaches and what they must have done:
If any party, or a person who at the time a deposition is taken or an examination or inspection is made is an officer, director, member, employee or agent of a party or otherwise under a party's control, refuses to obey an order for disclosure or wilfully fails to disclose information which the court finds ought to have been disclosed pursuant to this article, the court may make such orders with regard to the failure or refusal as are just …
Two alternative triggers, and both are demanding:
Refusal to obey an order. There must be an order, and it must have been disobeyed. This is why a CPLR 3124 motion so often precedes a 3126 application — the order it produces creates the predicate.
Wilful failure to disclose. No prior order is needed here, but the failure must be wilful, and the court must find the information ought to have been disclosed. Ordinary lateness, negligence or disorganization does not meet the standard as written.
That threshold is the main structural difference from the federal rules. FRCP 37(a)(5) shifts fees almost automatically on a granted motion to compel, and FRCP 37(c)(1) excludes undisclosed evidence unless the failure was substantially justified or harmless — neither requires wilfulness. CPLR 3126 does.
The three named sanctions
The section lists them "among" the just orders available, so the list is illustrative rather than exhaustive:
- Resolution of issues. "[A]n order that the issues to which the information is relevant shall be deemed resolved for purposes of the action in accordance with the claims of the party obtaining the order."
- Preclusion. An order prohibiting the disobedient party "from supporting or opposing designated claims or defenses, from producing in evidence designated things or items of testimony, or from introducing any evidence of the physical, mental or blood condition sought to be determined, or from using certain witnesses."
- Striking, staying, dismissal or default. An order "striking out pleadings or parts thereof, or staying further proceedings until the order is obeyed, or dismissing the action or any part thereof, or rendering a judgment by default against the disobedient party."
They escalate, and the third contains the case-ending remedies. Because the list is prefaced by "such orders … as are just," courts routinely impose lesser or conditional relief — a conditional order of preclusion or dismissal that takes effect only if compliance doesn't follow by a stated date is a common New York disposition, and it is authorized by the "as are just" language rather than by any enumerated item.
Protective orders — CPLR 3103
CPLR 3103(a) lets the court, on motion of any party or of any person from whom or about whom discovery is sought, or on its own initiative, make a protective order "denying, limiting, conditioning or regulating the use of any disclosure device," designed to prevent unreasonable annoyance, expense, embarrassment, disadvantage, or other prejudice to any person or the courts.
Two features are worth knowing.
Standing is broad. Not just parties — any person from whom or about whom discovery is sought.
CPLR 3103(b) is a stay by operation of the statute. Service of a notice of motion for a protective order suspends disclosure of the particular matter in dispute. Moving for protection stops the clock on that item without a further order.
CPLR 3103(c) covers improperly obtained disclosure: if it appears that disclosure was improperly or irregularly obtained so that a substantial right of a party is prejudiced, the court may make an appropriate order, including one that the information be suppressed.
What is discoverable in the first place
CPLR 3101(a) sets the scope: "There shall be full disclosure of all matter material and necessary in the prosecution or defense of an action, regardless of the burden of proof."
"Material and necessary" is New York's formulation, and it is construed liberally. The subdivision then lists who is subject to disclosure — parties, officers and employees, and, on the showings the paragraphs require, non-parties.
CPLR 3101(b) makes privileged matter not obtainable. CPLR 3101(c) does the same for attorney work product. CPLR 3101(d) governs trial preparation materials and expert disclosure, with the conditional protection for materials prepared in anticipation of litigation.
The practical sequence
- Check the part rules first. The affirmation of good faith and any conference requirement come from the Uniform Rules and the individual part, not from the CPLR.
- Move to compel under CPLR 3124. No deadline in the statute; no notice-to-admit disputes.
- Get an order. It is the predicate that makes CPLR 3126's first trigger available.
- If it is disobeyed — or the failure was wilful without an order — move under CPLR 3126, and ask for relief proportionate to the failure. Conditional orders are the norm.
- If you are the one resisting, CPLR 3103(b) means serving the protective-order motion suspends disclosure of that matter immediately.
Where this differs from what we cover elsewhere
| New York | Federal | California | |
|---|---|---|---|
| Motion to compel | CPLR 3124, no deadline stated | FRCP 37(a), certification required in the motion | 45 days from a verified response for further responses; no limit for no response |
| Meet and confer | Uniform Rules, not the CPLR | FRCP 37(a)(1), in the rule | CCP 2016.040 declaration, in the statute |
| Fee shifting on the motion | not automatic | FRCP 37(a)(5), presumptive both ways | CCP 2030.300(d) etc., presumptive both ways |
| Sanctions threshold | refusal to obey an order, or wilful failure | failure to obey an order; separately, non-disclosure unless substantially justified or harmless | failure to obey; waiver on a late response |
| Automatic consequence for lateness | none | FRCP 36 admissions; FRCP 37(c)(1) exclusion | waiver of all objections including privilege |
New York is the most forgiving of the three about lateness alone, and the most demanding about what must be shown before real sanctions issue.

The Uniform Rules for the New York State trial courts, and individual part rules, supply the conferral and motion-practice requirements the CPLR leaves open. This page explains what the CPLR says. It isn't legal advice.
