A.M. Med. Servs., P.C. v Liberty Mut. Ins. Co., 2010 NY Slip Op 20416 (App. Term 2d Dept. 2010)

“Defendant argued that the default judgment had been obtained through plaintiff’s fraud, misrepresentation or misconduct since the claim forms plaintiff had annexed to its motions contained handwritten notations which were not on the original claim forms included with the complaint and provided to defendant, and the motions were supported by affidavits containing false statements”

By the way, this “intrinsic fraud” was discussed in:  P__DG Psychological, P.C. v. State Farm Ins. Co., 9 Misc.3d 172 (Civ. Ct. Queens Co. 2005).

Here is the rule of law: “CPLR 5015 (a) (3) provides that a judgment may be vacated on the ground of “fraud, misrepresentation, or other misconduct of an adverse party.” When a defendant’s CPLR 5015 (a) [*2](3) motion alleges intrinsic fraud – – i.e., that the plaintiff’s allegations are false – – the defendant must also provide a reasonable excuse for its default (see Bank of NY v Stradford, 55 AD3d 765 ; Bank of NY v Lagakos, 27 AD3d 678 ).

In support of its motion, defendant argued that plaintiff had submitted affidavits which contained false statements and that plaintiff had annexed to its motion papers false documentation. Defendant was, thus, alleging that plaintiff had obtained the default judgment through “intrinsic fraud” (Bank of NY v Lagakos, 27 AD3d at 679). Consequently, defendant was required to show a reasonable excuse for its default (see Bank of NY v Stradford, 55 AD3d at 765-766), which defendant failed to do. The affirmation of defendant’s attorney did not show that counsel had personal knowledge of any facts pertaining to the alleged law office failure and, therefore, the affirmation was insufficient to establish an excuse for the default (see Incorporated Vil. of Hempstead v Jablonsky, 285 AD2d 553, 554 ). Further, since defendant’s attorney’s “supplemental” affirmation was, in fact, a reply affirmation, the factual allegations asserted for the first time therein must be disregarded (see McNair v Lee, 24 AD3d 159 ; Juseinoski v Board of Educ. of City of New York, 15 AD3d 353, 355 ).”

There was a dissent that unearthed certain issues regarding what comprised the law office failure.  The attorneys named in the dissent are competent and good attorneys, having worked with both of them.   As those who practice no-fault or other types of mass collection practices know, the nature and volume of these types of practices sometimes causes things to go awry.


Legal Update (February 2026): Since this 2010 post, CPLR 5015 motion practice and standards for vacating defaults based on intrinsic fraud may have evolved through subsequent appellate decisions and procedural amendments. Practitioners should verify current case law interpretations regarding the reasonable excuse requirement and documentation standards for fraud-based motions to vacate default judgments.

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.

Default Judgments in New York Practice

Default judgments arise when a party fails to answer, appear, or respond within required time limits. Vacating a default under CPLR 5015 requires showing a reasonable excuse for the failure and a meritorious defense or cause of action. In no-fault practice, defaults occur frequently in arbitration and court proceedings, and the standards for granting and vacating defaults have generated substantial case law. These articles analyze default practice, restoration motions, and the circumstances under which courts excuse procedural failures.

Common Questions

Frequently Asked Questions

What is a default in New York civil litigation?

A default occurs when a party fails to respond to a legal action within the required time frame — for example, failing to answer a complaint within 20 or 30 days of service under CPLR 320. When a defendant defaults, the plaintiff can seek a default judgment under CPLR 3215. However, a defaulting party can move to vacate the default under CPLR 5015(a) by showing a reasonable excuse for the delay and a meritorious defense to the action.

What constitutes a 'reasonable excuse' to vacate a default?

Courts evaluate reasonable excuse on a case-by-case basis. Accepted excuses can include law office failure (under certain circumstances), illness, lack of actual notice of the proceeding, or excusable neglect. However, mere neglect or carelessness is generally insufficient. The movant must also demonstrate a meritorious defense — meaning they have a viable defense to the underlying claim that warrants a determination on the merits.

Understanding New York Defaults Law

New York has a unique legal landscape that affects how defaults cases are litigated and resolved. The state's court system includes the Civil Court (for claims up to $25,000), the Supreme Court (the primary trial court for unlimited jurisdiction), the Appellate Term (which hears appeals from lower courts), the Appellate Division (divided into four Departments, with the Second Department covering Long Island, Brooklyn, Queens, Staten Island, and several upstate counties), and the Court of Appeals (the state's highest court). Each court has its own procedural requirements, local rules, and case-assignment practices that can significantly impact the outcome of your case.

For defaults matters on Long Island, cases are typically filed in Nassau County Supreme Court (at the courthouse in Mineola) or Suffolk County Supreme Court (in Riverhead). No-fault arbitrations are heard through the American Arbitration Association, which assigns arbitrators throughout the metropolitan area. Workers' compensation claims go to the Workers' Compensation Board, with hearings at district offices across the state. Understanding which forum is appropriate for your case — and the specific procedural rules that apply — is essential for a successful outcome.

The procedural landscape in New York also includes important timing requirements that can affect your case. Most civil actions are subject to statutes of limitations ranging from one year (for intentional torts and claims against municipalities) to six years (for contract actions). Personal injury cases generally have a three-year deadline under CPLR 214(5), while medical malpractice claims must be filed within two and a half years under CPLR 214-a. No-fault insurance claims have their own regulatory deadlines, including 30-day filing requirements for applications and 45-day deadlines for provider claims. Understanding and complying with these deadlines is critical — missing a filing deadline can permanently bar your claim, regardless of how strong your case may be on the merits.

Attorney Jason Tenenbaum regularly practices in all of these venues. His office at 326 Walt Whitman Road, Suite C, Huntington Station, NY 11746, is centrally located on Long Island, providing convenient access to courts and offices throughout Nassau County, Suffolk County, and New York City. Whether you need representation in a no-fault arbitration, a personal injury trial, an employment discrimination hearing, or an appeal to the Appellate Division, the Law Office of Jason Tenenbaum, P.C. brings $24+ years of real courtroom experience to your case. If you have questions about the legal issues discussed in this article, call (516) 750-0595 for a free, no-obligation consultation.

New York's substantive law also presents distinct challenges. In motor vehicle cases, the no-fault system under Insurance Law Article 51 provides first-party benefits regardless of fault, but limits the right to sue for non-economic damages unless the plaintiff establishes a "serious injury" under one of nine statutory categories. This threshold — codified at Insurance Law Section 5102(d) — requires medical evidence showing more than a minor or subjective injury, and courts have developed detailed standards for each category. Fractures must be documented through imaging studies. Claims of permanent consequential limitation or significant limitation of use require quantified range-of-motion testing with comparison to norms. The 90/180-day category demands proof that the plaintiff was unable to perform substantially all of their usual daily activities for at least 90 of the 180 days following the accident.

In employment discrimination cases, the legal standards vary depending on whether the claim arises under state or local law. The New York State Human Rights Law employs a burden-shifting framework: the plaintiff must first establish a prima facie case by showing membership in a protected class, qualification for the position, an adverse employment action, and circumstances giving rise to an inference of discrimination. The burden then shifts to the employer to articulate a legitimate, non-discriminatory reason for its decision. If the employer meets this burden, the plaintiff must demonstrate that the stated reason is pretextual. The New York City Human Rights Law, by contrast, applies a broader standard, asking whether the plaintiff was treated less well than other employees because of a protected characteristic.
