Opposing a Motion for Summary Judgment in New York: Rules, Evidence, and Strategy

Meta description: Learn how to oppose a motion for summary judgment in New York, meet filing deadlines, present admissible evidence, and show why a genuine factual dispute requires a trial.

A motion for summary judgment asks a New York court to decide a claim or defense without a trial. An effective opposition does more than disagree with the moving party: it responds to the legal arguments, supports relevant facts with competent evidence, and explains why the court cannot resolve the dispute as a matter of law. Understanding the deadlines, evidentiary requirements, and burden-shifting process can help parties prepare a focused and persuasive response.

What a Summary Judgment Motion Seeks

Under New York Civil Practice Law and Rules (CPLR) 3212, a party may ask the court to grant judgment when the material facts are not genuinely disputed and the law entitles that party to win. The motion may concern an entire case, a particular claim, or a specific defense. A court can also grant partial summary judgment on issues that are established, leaving other issues for trial.

New York courts do not use summary judgment to choose which witness is more believable or decide disputed facts that matter to the outcome. The court generally views the evidence in the light most favorable to the party opposing the motion. The key question is whether the record presents a genuine, material factual dispute that requires a trial.

The word material matters. A disagreement about a fact is not enough if resolving it differently would not affect the legal result. The opposition should connect each claimed factual dispute to an element of a claim, an affirmative defense, or another issue the court must decide.

Check the Deadline and Filing Requirements First

Timing can determine whether an opposition is considered. CPLR 2214(b) generally requires answering papers to be served at least two days before the return date stated in the notice of motion. The notice of motion ordinarily must be served at least eight days before that date. Different rules, court orders, stipulations, or electronic-filing procedures may alter the practical schedule, so the notice and the assigned court’s rules should be checked immediately.

For a cross-motion, CPLR 2215 generally requires service at least three days before the time set for the original motion, unless the court directs otherwise. A cross-motion is not simply an opposition with a different label: it asks the court for affirmative relief and must satisfy applicable notice and filing requirements. A party seeking relief should confirm whether a cross-motion is appropriate and permitted in the case.

CPLR 3212(a) generally allows a summary judgment motion after issue has been joined—that is, after the relevant pleadings have been served—and no later than 120 days after the filing of the note of issue, unless the court sets another deadline. A late motion requires good cause for the delay. In Brill v. City of New York, 2 N.Y.3d 648 (2004), the Court of Appeals enforced the statutory good-cause requirement. Although a late motion may sometimes be considered when it is genuinely responsive to a timely motion, parties should not assume that exception applies.

New York Supreme Court and county-specific rules may require particular filing practices, working copies, page limits, or procedures for exhibits and oral argument. In e-filed cases, the New York State Courts Electronic Filing system (NYSCEF) rules and the court’s directives also matter. The assigned judge’s individual practices should be reviewed before papers are submitted.

Understand the Burden-Shifting Standard

The moving party has the initial burden. It must establish, with evidence, a legal right to judgment and show that no material factual issue requires trial. If the moving party fails to meet that burden, the court should deny the motion even if the opposition is weak. This rule is stated in Winegrad v. New York University Medical Center, 64 N.Y.2d 851 (1985).

If the moving party meets its initial burden, the opposing party must produce evidence showing a genuine dispute of material fact or another legal reason the motion should fail. In Alvarez v. Prospect Hospital, 68 N.Y.2d 320 (1986), the Court of Appeals explained this burden-shifting framework. Conclusory denials and unsupported allegations generally do not suffice.

In practice, the opposition should address the moving party’s proof point by point. It can identify evidence that contradicts a material assertion, demonstrate that a cited document does not establish the fact claimed, or explain why the moving party’s legal argument does not follow from the record. A strong response is specific: it identifies the disputed fact, cites the supporting record evidence, and explains why the dispute matters.

Use Evidence the Court Can Consider

CPLR 3212(b) requires the motion to be supported by evidence in admissible form. The same principle is central to an opposition. A factual assertion in a memorandum of law is not evidence, and an attorney’s argument cannot replace a witness with personal knowledge. The papers should cite evidence that could be presented in admissible form at trial, subject to applicable evidentiary rules.

Affidavits and affirmations

A witness affidavit should be based on personal knowledge, describe facts rather than unsupported conclusions, and be properly sworn. An attorney affirmation may organize the argument, identify the record, and attach or cite documents, but it normally cannot establish facts the attorney did not personally observe. In New York, an attorney affirmation may be used in place of an affidavit when permitted by CPLR 2106, as amended; the signer must meet the statute’s requirements.

Each statement should be precise. For example, a witness who personally saw a condition can describe its location and appearance. A statement that a property owner “must have known” about the condition, without a factual basis, is an inference or conclusion rather than firsthand proof. If the statement relies on information from another person, the opposition should address whether a hearsay exception or other evidentiary basis applies.

Documents, records, and deposition testimony

Attach relevant documents in an organized way and explain their significance. Business records often require a foundation under CPLR 4518, typically through testimony or an appropriate certification establishing that the record was made and kept in the regular course of business. Merely attaching a document does not always establish that it is authentic or admissible.

Deposition testimony can be important, but the transcript should be properly prepared and submitted in a form the court can consider. Check applicable rules governing the transcript, including whether it was signed or whether the parties waived signature. Cite page and line numbers so the court can locate the testimony quickly. The same care applies to contracts, photographs, emails, medical records, and other exhibits: authenticate them where needed and provide context.

Expert proof

When a claim or defense depends on specialized knowledge, a qualified expert may need to explain the relevant standard, methodology, or causal connection. An expert affidavit should state the expert’s qualifications, identify the materials reviewed, and provide a reasoned explanation rather than a bare conclusion. The opinion should address the specific argument raised by the motion and be grounded in the record.

Build the Opposition Around the Record

A useful opposition typically includes a memorandum of law, an affidavit or affirmation from a person with relevant knowledge, and exhibits cited in the papers. The exact components depend on the case and the court’s rules. A separate response to the moving party’s statement of material facts may also be required by local rules or a judge’s individual practices.

A clear structure helps the court evaluate the response. One practical approach is to:

• Identify the legal test. State the claim, defense, or rule that controls the motion.
• Respond to each material assertion. Admit, deny, or qualify the assertion and cite specific evidence.
• Explain why the evidence matters. Connect the disputed fact to an element, defense, or legal issue.
• Address weaknesses directly. Explain gaps or inconsistencies in the moving party’s proof without overstating the record.
• Request precise relief. Ask the court to deny the motion, deny a particular portion, or grant other relief supported by the papers.

For example, in a negligence case, a disagreement about whether a hazard existed may be material if the claim depends on that condition. A witness’s sworn description, a properly supported photograph, or deposition testimony may create a factual issue. By contrast, a general assertion that “the defendant was negligent,” without evidence of the relevant conduct or circumstances, is unlikely to be enough.

When More Discovery Is Needed

If essential facts are unavailable because discovery is incomplete, CPLR 3212(f) may provide a basis to ask the court to deny the motion or defer its determination. The request should explain what facts remain unavailable, why they are material to the motion, and what discovery is expected to produce them. A general statement that discovery is unfinished is usually less persuasive than identifying a specific witness, document, inspection, or deposition and explaining its relevance.

Courts may reject a request that appears to rely on speculation or to delay a decision when the party has had a fair opportunity to obtain the evidence. The opposition should show that the missing information is important and that reasonable steps have been taken to obtain it. If appropriate, it can ask for a limited adjournment or targeted discovery rather than an open-ended delay.

Use Partial Summary Judgment and Limited Relief Strategically

Opposing every part of a motion is not always the best approach. CPLR 3212(e) allows summary judgment on part of a claim or defense, while CPLR 3212(g) permits a court to identify facts that are not genuinely disputed and treat them as established for trial. The opposition can acknowledge an undisputed point while explaining why it does not resolve the remaining claim or defense.

This approach can improve clarity and credibility. If the record establishes one fact but leaves causation, notice, damages, intent, or another material issue disputed, the opposition should distinguish the established point from the unresolved issue. The requested relief should match that analysis—for example, denial of the motion in full, denial only as to a particular claim, or a ruling that leaves specified factual issues for trial.

Common Mistakes That Weaken an Opposition

• Relying on pleadings alone. Allegations in a complaint or answer are not a substitute for evidence once a properly supported summary judgment motion is made.
• Using conclusory statements. Broad claims that a party acted unlawfully or that a dispute exists do not show what evidence supports the position.
• Ignoring the moving party’s evidence. The response should address the specific proof and legal arguments presented, not simply repeat the complaint’s allegations.
• Submitting unsupported documents. Records may need authentication, a business-record foundation, or another basis for admissibility.
• Overlooking the deadline or local rules. Late papers, missing exhibits, or failure to follow a judge’s procedures can create avoidable problems.
• Failing to explain materiality. A factual disagreement matters only if it can affect the legal outcome.

How Courts Evaluate the Papers

New York courts examine the submissions as a whole, including pleadings, affidavits or affirmations, deposition transcripts, admissions, and other proof. In Zuckerman v. City of New York, 49 N.Y.2d 557 (1980), the Court of Appeals emphasized that a party opposing summary judgment must produce evidentiary proof in admissible form rather than rely on conclusory assertions.

The court generally does not resolve credibility disputes on a summary judgment motion. If competent evidence supports competing accounts of a material event, that conflict may require a factfinder at trial. But a dispute must be grounded in the record; unsupported speculation, minor inconsistencies, or differences unrelated to the legal elements may not prevent judgment.

Because procedural rules and evidentiary issues can be fact-specific, parties should verify current statutes, court rules, and judge-specific procedures before filing. A New York attorney can assess whether the motion is timely, whether the evidence is admissible, and which factual disputes are legally significant.
