How Do You File a Notice of Claim Against a City in New York?

Under New York General Municipal Law section 50-e, anyone injured by a dangerous condition on a city-owned street, sidewalk, or public property must serve a written Notice of Claim on the municipal corporation before starting a lawsuit. This requirement applies to claims against cities, counties, towns, villages, and many public authorities. It does not apply the same way to claims against a private landowner, which is why pothole and sidewalk cases involving a government entity follow a different set of rules than an ordinary slip and fall case.

Why Is a Claim Against a City Different From a Claim Against a Private Owner?

Municipal corporations are treated differently under New York law because they are public entities funded by taxpayers and responsible for maintaining an enormous amount of infrastructure. To manage the volume of potential claims and give the city a chance to investigate promptly, the legislature created procedural conditions that must be satisfied before a lawsuit can even be filed. Failing to meet these conditions, even where the underlying injury and negligence are clear, can prevent a claim from moving forward at all.

What Is a Notice of Claim and When Must It Be Filed?

A Notice of Claim is a formal written document that alerts the municipal corporation that a claim exists. Under General Municipal Law section 50-e(1)(a), the notice generally must be served within ninety days after the claim arises. This is far shorter than the time normally given to bring a negligence claim between private parties. The clock generally starts running on the date of the incident, not the date an injury is diagnosed or worsens.

What Must the Notice of Claim Contain?

General Municipal Law section 50-e(2) sets out what the notice must include. It must state the name and address of the claimant, the nature of the claim, the time, place, and manner in which the claim arose, and the injuries or damages claimed. A notice that is vague about the location of a defect, such as a pothole or a raised sidewalk slab, can create problems later if the city argues it never had a fair opportunity to investigate the specific spot at issue.

Does the City Have to Have Known About the Defect First?

For streets, sidewalks, and highways in New York City, the Administrative Code adds another layer beyond the Notice of Claim. Under Administrative Code section 7-201(c), sometimes called the prior written notice law, the city generally cannot be held liable for a defect in a roadway or sidewalk unless it received prior written notice of that specific condition, or unless the city itself created the dangerous condition through an affirmative act of negligence. This means that even a well-documented, serious pothole may not support a claim against the city if there is no record that the city was told about it in advance, and if the defect was not caused by the city's own work.

Who Is Responsible, the City or the Property Owner Next Door?

Not every sidewalk defect is the city's responsibility. Administrative Code section 7-210 shifts the duty to maintain and repair sidewalks in New York City to the owners of the abutting property in most cases. An important exception exists for owner-occupied properties with one, two, or three family homes that are used exclusively for residential purposes. Those small residential owners are generally not covered by section 7-210, and liability for a sidewalk defect in front of that kind of home may fall back on the city. Determining whether the responsible party is the city, a property owner, or both often requires reviewing property records, prior repair history, and any permits for work performed near the defect.

What Happens After the Notice of Claim Is Served?

Once a Notice of Claim is served, General Municipal Law section 50-h gives the municipal corporation the right to demand that the claimant appear for a sworn examination before any lawsuit is filed. This hearing allows the city to question the claimant about how the incident happened, the location of the defect, and the injuries claimed. Under General Municipal Law section 50-i, a lawsuit generally cannot be commenced until either this hearing has been held or thirty days have passed since the demand was made without the hearing taking place, and until at least thirty days have passed since the Notice of Claim was served, unless the city has explicitly refused or rejected the claim sooner.

What Are the Deadlines?

Several deadlines apply to a claim involving a city street or sidewalk defect, and the shortest one controls. The Notice of Claim itself must generally be served within ninety days of the incident under General Municipal Law section 50-e. Separately, General Municipal Law section 50-i sets an outer limit for actually commencing the lawsuit, generally within one year and ninety days of the date the claim arose. Claims involving a public entity therefore carry a much shorter notice requirement than the period ordinarily allowed for a negligence claim between two private individuals. Missing the ninety day notice window can bar a claim permanently, regardless of how much time might otherwise remain under a general limitations period, so the earliest applicable deadline is always the one that matters most.
