Notice of Claim Deadlines and Procedures for Suing a Government Entity in New York

Suffering an injury is difficult enough. When that harm happens on public property or through the actions of a government agency, the path to compensation involves rules that are far stricter—and far less forgiving—than a typical personal injury case.

Whether you slipped in a city park, were hit by an MTA bus, or were hurt by unsafe conditions in a NYCHA building, special procedural requirements apply before you can even file a lawsuit. Missing a single deadline can permanently bar you from recovering damages, no matter how serious your injuries.

Hill & Moin LLP has decades of experience guiding injured New Yorkers through these government claims procedures. This guide breaks down the Notice of Claim process, how it differs depending on which government entity is involved, and the mistakes that most often derail a valid claim.

You deserve a law firm that prioritizes your safety and recovery.

Why Government Claims Are Different from Standard Personal Injury Cases

In an ordinary personal injury case against a private individual or business, New York generally allows up to three years from the date of the accident to file a lawsuit. Claims against government entities operate under a completely different framework, rooted in the legal doctrine of sovereign immunity, which historically shielded government bodies from lawsuits unless the law specifically allowed them.

Today, several statutes waive that immunity for certain injury claims, but only if strict procedural steps are followed first. The most important of these is the Notice of Claim: a formal written document that must typically be filed within 90 days of the incident, long before any lawsuit is filed in court.

What Is a Notice of Claim?

A Notice of Claim is a written statement that formally alerts a government agency to your injury and your intent to seek compensation. It generally must include:

• The date, time, and location where the incident occurred
• A description of how the injury happened and the negligence involved
• The nature and extent of your injuries
• The names of any known witnesses

Service typically must be made by personal delivery or certified mail to the correct office. Sending it to the wrong department, missing required details, or misidentifying the responsible agency can jeopardize the claim before it even begins.

How the Process Differs by Government Entity

Not all government claims follow the same rules. The correct procedure depends on which entity you’re pursuing.

New York City and City Agencies

Claims against the City of New York and its agencies (such as the Department of Transportation, Department of Parks and Recreation, or NYPD) are governed by General Municipal Law §§ 50-e and 50-i. These require a Notice of Claim within 90 days of the incident, served on the New York City Comptroller’s Office. In many sidewalk cases, additional rules under the NYC Administrative Code and prior written notice requirements also apply. Our related guide on defective sidewalk claims against the city explains how these overlapping rules affect liability.

Counties, Towns, and Local Public Corporations

Similar to New York City, most counties, towns, villages, and local public corporations are also governed by General Municipal Law §§ 50-e and 50-i, requiring a 90-day Notice of Claim served on the appropriate municipal clerk or governing body before a lawsuit can proceed.

The MTA, NYC Transit Authority, and Other Public Authorities

Public authorities such as the Metropolitan Transportation Authority (MTA), New York City Transit Authority, and Triborough Bridge and Tunnel Authority are governed by the Public Authorities Law, which layers its own notice provisions on top of the standard 90-day requirement. Because these authorities often relate to multiple subsidiaries, correctly identifying the right entity to name in your notice is critical. Our detailed breakdown of MTA bus accident Notice of Claim procedures covers this in greater depth.

NYCHA (New York City Housing Authority)

NYCHA is treated as a municipal entity for Notice of Claim purposes, requiring the same 90-day window under General Municipal Law. NYCHA cases frequently turn on whether the agency had actual or constructive notice of a hazardous condition, such as a broken elevator, unsafe stairwell, or inadequate security. See our guide on filing a claim against NYCHA or the DOT for a closer look at these agency-specific rules.

State Agencies

Claims against New York State agencies and departments fall under the exclusive jurisdiction of the New York State Court of Claims, established by the Court of Claims Act. Rather than a standard Notice of Claim, these cases require filing a claim or notice of intention directly with the Court of Claims, generally within 90 days, and the case is litigated in that specialized court rather than a typical civil courtroom.

Timeline: From Incident to Lawsuit

Step	Typical Deadline
Incident occurs	Day 0
Notice of Claim served on the correct agency	Generally within 90 days
Government’s investigation period (50-h hearing may be requested)	Agency has time to investigate before litigation
Agency accepts, denies, or fails to respond to the claim	Varies by entity
Lawsuit must be commenced in court	Generally within 1 year and 90 days of the incident for many municipal claims

This timeline is a general framework; exact deadlines and procedures vary depending on the specific government entity involved, so it’s important to confirm the applicable rules for your case as early as possible.

Common Mistakes That Can Jeopardize a Government Claim

Because the process is so procedurally strict, small errors can have outsized consequences. Frequent mistakes include:

• Missing the 90-day window entirely, which can permanently bar the claim
• Serving the wrong office or agency, especially in cases involving overlapping jurisdiction between the city, a public authority, and a state agency
• Failing to include required details, such as a precise description of how and where the injury occurred
• Ignoring a 50-h hearing request, a pre-litigation examination the city or agency is often entitled to before a lawsuit is filed
• Misidentifying the responsible party, such as naming the city when a public authority or private contractor was actually responsible

Late Notice of Claim Applications and Other Exceptions

New York law does provide limited relief in some situations. Under General Municipal Law § 50-e(5), a court has discretion to permit a late Notice of Claim in certain circumstances, considering factors such as:

• Whether the government entity had actual knowledge of the facts within the 90-day window or shortly after
• Whether the delay would substantially prejudice the agency’s ability to investigate
• The reason for the delay, including cases involving a claimant’s infancy, incapacitation, or death

These exceptions are narrow and are not guaranteed. Courts have significant discretion, and outcomes vary widely, which makes it especially important to consult an attorney immediately after an incident rather than relying on the possibility of a late-filing exception.

Don’t wait—your future starts with one phone call.

Building a Strong Government Claim

Beyond timing, negligence claims against government entities require proving the same core elements as any personal injury case: a duty of care, a breach of that duty, causation, and damages. Useful evidence includes:

• Photographs of the unsafe condition or public property
• Witness statements from bystanders or fellow passengers
• Medical records documenting your injuries and treatment
• Maintenance logs, prior complaint records, or internal agency reports, when obtainable

For example, if NYCHA ignores a broken stairwell railing and a resident falls, prior complaint records and internal maintenance logs can be central to proving the agency knew about the hazard. Cases involving premises liability principles often overlap significantly with government claims when the hazard exists on public or agency-managed property.

Frequently Asked Questions

1. How long do I have to file a Notice of Claim in New York? In most cases involving New York City, counties, NYCHA, or public authorities like the MTA, you generally have 90 days from the date of the incident to serve a Notice of Claim.
2. What happens if I miss the Notice of Claim deadline? Missing the deadline can permanently bar your claim, though in limited circumstances a court may allow a late Notice of Claim under General Municipal Law § 50-e(5).
3. Is the process different for claims against the MTA versus New York City? Yes. While both generally require a 90-day Notice of Claim, the MTA and its subsidiaries are governed by the Public Authorities Law and involve their own internal procedures, separate from claims against city agencies.
4. Do claims against New York State agencies work the same way? No. Claims against state agencies are handled by the New York State Court of Claims under the Court of Claims Act, rather than through the municipal Notice of Claim process.
5. Can I still sue if the government denies my claim? Yes. If a claim is denied or the agency fails to respond, you may proceed to file a lawsuit in the appropriate court, provided you do so within the applicable statute of limitations.
6. What is a 50-h hearing? A 50-h hearing is a pre-litigation examination that a municipal entity is often entitled to request, allowing the agency to question the claimant under oath about the incident before a lawsuit is filed.
7. Why should I hire an attorney instead of filing the Notice of Claim myself? The technical requirements for identifying the correct agency, serving the notice properly, and meeting overlapping deadlines are easy to get wrong, and a single mistake can permanently end an otherwise valid claim.
