Contract of insurance is vitiated?

By Jason Tenenbaum 8 min read

Key Takeaway

New York insurance law requires timely notice of claims. When insureds fail to provide proper notice, the entire insurance contract can be voided, leaving them without coverage.

Insurance contracts contain specific requirements that both parties must follow. One of the most critical obligations for policyholders is providing timely notice of potential claims to their insurance company. This requirement isn’t just a formality — failure to comply can have devastating consequences.

Under New York No-Fault Insurance Law, when an insured fails to provide proper notice of a claim, the insurance company can disclaim coverage entirely. This means the contract becomes void, and the policyholder loses their right to coverage for that incident. The courts have consistently upheld this harsh consequence, emphasizing that notice provisions are fundamental to how insurance contracts operate.

The timing of the insurance company’s response is equally important. Insurers must act quickly once they receive notice — they cannot sit on information and then later claim the notice was inadequate. This case demonstrates how these competing obligations work in practice, with both the insured’s duty to notify and the insurer’s duty to respond promptly playing crucial roles.

Jason Tenenbaum’s Analysis:

Ciampa Estates, LLC v Tower Ins. Co. of N.Y., 2011 NY Slip Op 03911 (1st Dept. 2011)

“An insured’s failure to comply with the notice of claim provision vitiates a contract of insurance (see Great Canal Realty Corp. v Seneca Ins. Co., 5 NY3d 742, 743 )”

“Furthermore, because defendant sent out its disclaimer of coverage within six days of ultimately receiving a notice of claim on behalf of Estates, the disclaimer was timely as a matter of law under Insurance Law § 3420”

Someone please explain this all to me… Coverage? Policy exclusion? Who knows? Who cares? Huh?

Key Takeaway

This case illustrates the strict enforcement of notice requirements in insurance contracts. When policyholders fail to provide timely notice of claims, courts will void the entire insurance contract, leaving them without any coverage. However, insurance companies must also act quickly — once they receive notice, they have limited time to disclaim coverage or risk waiving their right to do so.


Legal Update (February 2026): Since this 2011 post, New York’s no-fault insurance regulations under Insurance Law § 3420 may have been subject to amendments regarding notice requirements, disclaimer procedures, and insurer response timeframes. Practitioners should verify current statutory provisions and recent case law developments that may have modified notice obligations or the “vitiation” standards discussed in this analysis.

I’m still scratching my head in light of this Court’s ruling that an insurer never has to timely disclaim– or disclaim whatsoever– regarding any purported condition breach, merely because it concerns a No-Fault insurance. Chubb is just as clear as Insurance Law § 3420 and is even more controlling than statute because it’s an interpretation of an existing statute by the highest court of the State. Yet now, this Court is telling everyone– directly contrary to Chubb– that the insurer can sit on its purported defense as long as it wants, for no policy gain whatsoever. Still amazes me…
