Understanding How Jurisdictional Defenses Can Be Waived Through Defendant Conduct

In New York civil litigation, defendants often attempt to challenge a court’s jurisdiction over them as a defense strategy. However, courts have consistently held that certain actions by defendants can waive these jurisdictional challenges, even when the defendant later claims the court lacked authority to enter judgment. A recent appellate decision demonstrates how seemingly innocent communications with opposing counsel can destroy an otherwise valid jurisdictional defense.

The concept of waiver in jurisdictional matters is particularly significant because it shows how defendants’ own conduct can undermine their legal position. Unlike other defenses that must be explicitly abandoned, jurisdictional defenses can be waived through implicit acknowledgment of the court’s authority or through unreasonable delays in asserting the defense.

“Nevertheless, a lack of jurisdiction claim will be deemed waived where a defendant has implicitly acknowledged the validity of a default judgment or has unreasonably delayed in moving to vacate the judgment (see Cadlerock Joint Venture, L.P. v Kierstedt, 119 AD3d 627, 628 ; Taveras v City of New York, 108 AD3d 614, 617 ; HSBC Bank USA, N.A. v A & R Trucking Co., Inc., 66 AD3d 606 ). Here, it is undisputed that seven years before moving to vacate the judgment, defendant had called plaintiff’s attorney’s office in order to negotiate payment of the judgment. Defendant thereby implicitly acknowledged the existence of the judgment and demonstrated a lack of good faith by dilatorily asserting his rights.”

Key Takeaway

This case illustrates that defendants cannot have it both ways — they cannot negotiate payment of a judgment while simultaneously claiming the court lacked jurisdiction to enter that judgment. The seven-year delay between the defendant’s acknowledgment and the motion to vacate demonstrated bad faith and resulted in waiver of the jurisdictional defense. This principle applies broadly beyond jurisdictional defects to various procedural challenges in New York courts.

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.

New York law varies by jurisdiction — court decisions in one Appellate Division department may not be followed in another, and local court rules in Nassau County Supreme Court differ from those in Suffolk County Supreme Court, Kings County Civil Court, or Queens County Supreme Court. 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.
