Oh man, how many times do you get an EBT or EUO transcript that has an errata sheet that actually rewrote the examination? I will one of these days put on here an EUO I did where EIP admitted that he was a ULD (unlisted driver) and then in his errata sheet changed all of the answers.
Here is the case: Ashford v Tannenhauser, 2013 NY Slip Op 05508 (2d Dept. 2013)
“In his post-deposition errata sheet, the injured plaintiff radically changed much of his earlier testimony, with the vague explanation that he had been “nervous” during his deposition. CPLR 3116(a) provides that a “deposition shall be submitted to the witness for examination and shall be read to or by him or her, and any changes in form or substance which the witness desires to make shall be entered at the end of the deposition with a statement of reasons given by the witness for making them.” Since the injured plaintiff failed to offer an adequate reason for materially altering the substance of his deposition testimony, the altered testimony could not properly be considered in determining the existence of a triable issue of fact as to whether a defect in, or the inadequacy of, the ladder caused his fall (see Garcia-Rosales v Bais Rochel Resort, 100 AD3d 687; Shell v Kone El. Co., 90 AD3d 890; Thompson v Commack Multiplex Cinemas, 83 AD3d 929; Kuzimin v Visiting Nurse Serv. of N.Y., 56 AD3d 438, 439). In the absence of the proposed alterations, the injured plaintiff’s deposition testimony was insufficient to raise a triable issue of fact with respect to the defectiveness or inadequacy of the ladder so as to warrant the denial of summary judgment. Likewise, in opposition to the defendants’ prima facie showing that the trust was an out-of-possession landlord with no duty to repair or maintain the ladder or the floor, the plaintiffs failed to raise a triable issue of fact. Therefore, the Supreme Court erred in denying the defendants’ motion for summary judgment dismissing the complaint.”

Legal Update (February 2026): Since this 2013 post, the standards governing errata sheet submissions and acceptable reasons for testimony changes under CPLR 3116(a) may have evolved through subsequent appellate decisions and procedural amendments. Practitioners should verify current judicial interpretations of what constitutes “adequate reason” for material alterations to deposition testimony, as courts have continued to refine the boundaries between permissible corrections and impermissible substantive changes.
Legal Context
Why This Matters for Your Case
New York law is among the most complex and nuanced in the country, with distinct procedural rules, substantive doctrines, and court systems that differ significantly from other jurisdictions. The Civil Practice Law and Rules (CPLR) governs every stage of civil litigation, from service of process through trial and appeal. The Appellate Division, Appellate Term, and Court of Appeals create a rich and ever-evolving body of case law that practitioners must follow.
Attorney Jason Tenenbaum has practiced across these areas for over 24 years, writing more than 1,000 appellate briefs and publishing over 2,353 legal articles that attorneys and clients rely on for guidance. The analysis in this article reflects real courtroom experience — from motion practice in Civil Court and Supreme Court to oral arguments before the Appellate Division — and a deep understanding of how New York courts actually apply the law in practice.

Discovery Practice in New York Courts
Discovery is the pre-trial process through which parties exchange information relevant to the dispute. In New York, discovery practice is governed by CPLR Article 31 and involves depositions, interrogatories, document demands, and physical examinations. Disputes over the scope of discovery, compliance with demands, and sanctions for noncompliance are frequent in both no-fault and personal injury cases. These articles analyze discovery rules, court decisions on discovery disputes, and strategies for effective discovery practice.

Frequently Asked Questions
What is discovery in New York civil litigation?
Discovery is the pre-trial phase where parties exchange relevant information and evidence. Under CPLR Article 31, discovery methods include depositions (oral questioning under oath), interrogatories (written questions), document demands, requests for admission, and physical or mental examinations. Discovery in New York is governed by the principle of full disclosure of all relevant, non-privileged information — but courts can issue protective orders to limit discovery that is overly broad or burdensome.
What happens if a party fails to comply with discovery requests?
Under CPLR 3126, a court can impose penalties for failure to comply with discovery, including preclusion of evidence, striking of pleadings, or even dismissal of the action or entry of a default judgment. Before seeking sanctions, the requesting party typically must demonstrate a good-faith effort to resolve the dispute and may need to file a motion to compel disclosure under CPLR 3124.
What are interrogatories and how are they used in New York litigation?
Interrogatories are written questions served on the opposing party that must be answered under oath within a specified timeframe. Under CPLR 3130, interrogatories in New York are limited — a party may serve a maximum of 25 interrogatories, including subparts, without court permission. Interrogatories are useful for obtaining basic factual information such as witness names, insurance details, and factual contentions. Objections must be specific and timely or they may be waived.
What is a bill of particulars in New York personal injury cases?
A bill of particulars under CPLR 3043 and 3044 provides the defendant with the specific details of the plaintiff's claims — including the injuries sustained, the theory of liability, and the damages sought. In personal injury cases, it must specify each injury, the body parts affected, and the nature of the damages claimed. An amended or supplemental bill may be served to include new injuries or updated information discovered during the course of litigation.
What is an Examination Before Trial (EBT)?
An EBT, commonly called a deposition, is a pre-trial discovery tool under CPLR 3107 where a witness answers questions under oath. In personal injury and no-fault cases, EBTs are used to lock in testimony, assess witness credibility, and uncover facts relevant to the case. Both plaintiffs and defendants can be deposed, along with medical experts, claims adjusters, and other witnesses. EBT testimony can be used at trial for impeachment or as evidence if the witness is unavailable.

The Appellate Division, Second Department (which covers Long Island, Brooklyn, Queens, and Staten Island) and the Appellate Term (which hears appeals from lower courts) each have distinct procedural requirements and precedents that affect litigation strategy.
