This article was published May 20, 2011. Corrected September 22, 2026: the earlier text cited Thibeault v Travelers Ins. Co., 37 AD3d 1000, as a Second Department decision. The official reporter shows it is a Third Department decision, decided February 22, 2007, on appeal from Supreme Court, Saratoga County (Rose, J.; Mercure, J.P., Peters, Carpinello and Lahtinen, JJ., concurring). The text below states the rule as verified.
Proving Insurance Notice Delivery: When Incomplete Addresses Matter
In insurance litigation, an insurer that has to prove it sent a notice (a cancellation, a denial, a verification request, an examination notice) usually proves it by describing the office practice it uses to make sure such notices are properly mailed. Once it does, a presumption arises that the notice was received, and the burden shifts to the insured to rebut it (Nassau Ins. Co. v Murray, 46 NY2d 828 (1978), as applied in Thibeault). A bare denial of receipt does not rebut the presumption.
Thibeault v Travelers Ins. Co., 37 AD3d 1000 (3d Dept 2007), decided February 22, 2007, shows what does. The insureds made a fire loss claim under a homeowner’s policy. The insurer denied it on the ground that the policy had been canceled for nonpayment before the fire, and proved its mailing practice for cancellation notices. The insureds answered with proof that the address the insurer used left out the name of the business under which their post office box was registered, and that under United States Postal Service practice a mailing addressed to them without the business name would not be delivered to that box. The Third Department held that this evidence rebutted the presumption and raised a question of fact on delivery, and it reversed the summary judgment the insurer had won.
The same rule decides no-fault disputes over whether a denial or an examination notice was ever mailed: proof of the office practice raises the presumption, and only evidence that the mailing as addressed could not have been delivered, not a denial of receipt alone, defeats it.

“While it is true that an insured’s denial of receipt, standing alone, is insufficient to rebut the presumption (see id. at 829-830), here there is additional evidence that an omission in the address as stated on the Thibeaults’ policy application and used by defendant prevented delivery of the notice. There is no dispute that the address was incomplete, inasmuch as it left out the name of the Thibeaults’ business under which the post office box was registered. Because the Thibeaults submitted evidence that a mailing addressed solely to them, without the name of the business, would not be delivered to the post office box due to United States Postal Service practices, they succeeded in rebutting the presumption and raising a question of fact as to delivery of the notice”
Key Takeaway
Denying receipt of an insurance notice is not enough to overcome the presumption of delivery that arises from proof of the insurer’s mailing practice. Evidence that a defect in the address prevented delivery, such as a missing business name that postal practice required, rebuts the presumption and creates a question of fact on whether the notice was received.

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 2,600 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.
About This Topic
Proof of Mailing in New York No-Fault Practice
Proof of mailing is a foundational issue in no-fault litigation. Insurers must prove timely mailing of denial forms, verification requests, and EUO scheduling letters, while providers and claimants must prove timely submission of claim forms and bills. Establishing a standard office mailing procedure through business records — and the presumption of receipt that follows — is heavily litigated. These articles examine the evidentiary standards for proving and challenging mailing in New York no-fault cases.

Why is proof of mailing important in no-fault litigation?
Proof of mailing matters because many no-fault defenses depend on showing that a denial, verification request, or examination notice was actually sent on time. Under 11 NYCRR 65-3.8(c) the insurer must pay or deny a claim within 30 calendar days after receiving proof of claim, so an insurer that cannot prove a timely mailing loses that defense. Courts presume a properly mailed notice was received once the sender proves its office mailing practice. In Thibeault v Travelers Ins. Co., 37 AD3d 1000 (3d Dept 2007), a denial of receipt alone did not rebut the presumption, but proof that the address used was incomplete and undeliverable raised a question of fact.

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.
