What happened: A New York appeals court affirmed the voiding of a homeowner’s insurance policies after the insured property proved to be a three-family dwelling.
Who’s involved: Otsego Mutual Fire Insurance Company and a Long Island homeowner.
What’s at stake: The homeowner’s water damage coverage and the validity of the policies from inception.
Why it matters: Insurers can void policies ab initio when applicants misrepresent property use, even if a broker completed the application.
Where it stands: Affirmed by the Appellate Division, Second Department, on October 7, 2026; uncorrected slip opinion.
A broken pipe led to a water damage claim. The claim led to an investigation. The investigation cost a Long Island homeowner her insurance.
New York’s Appellate Division, Second Department, has affirmed a ruling that Otsego Mutual Fire Insurance Company was entitled to void the homeowner’s insurance policies after discovering the insured property in Bay Shore was a three-family dwelling - not the single-family home declared on the application.
The homeowner purchased the house in July 2015. Her broker filled out the insurance application, representing the number of families in the dwelling as one. Otsego issued a homeowners’ policy on that basis and renewed it in subsequent years.
In January 2020, a pipe broke and the homeowner filed a water damage claim. During its investigation, Otsego found something else entirely: three separate apartment units, each with its own kitchen, bathroom, living and sleeping space, and its own access to the outside. The insurer concluded the house was a three-family dwelling, disclaimed coverage, and voided the policy.
The homeowner sued for breach of contract in May 2021. Otsego counterclaimed, seeking a court declaration that the policies were void from the start - void ab initio, meaning they were treated as though they never existed.
Suffolk County Supreme Court granted Otsego’s motion for summary judgment and denied the homeowner’s cross-motion. The homeowner appealed.
The appellate court affirmed. Otsego’s Director of Underwriting submitted an affidavit alongside the company’s 2015 Downstate Underwriting Guidelines, establishing that the insurer did not insure three-family dwellings and would not have issued the policy had the correct information been disclosed. The court found the misrepresentation was material.
The homeowner argued the application question - which asked for the number of families - was ambiguous. The court disagreed, citing prior appellate decisions that found the same question unambiguous. Then came the detail that sealed it: the homeowner admitted she never read the application before signing it. She could not claim to have been misled by language she never saw.
A material misrepresentation on an insurance application can void coverage from inception - regardless of whether the applicant or her broker filled out the form. Property-use verification at the application stage remains the strongest safeguard against exactly this kind of post-loss dispute.
