This all depends on what type of claim you have. For basic negligence cases (accident cases against private entities), the statute of limitations is 3 years. For cases against the City of New York and other public municipalities, the statute of limitations is generally 1 year and 90 days. However, there are other deadlines that you must be aware of.
For example, for all car crash cases, there is a No-Fault deadline of 30 days. For all cases involving a public municipality, there is a 90 day Notice of Claim deadline. For general medical malpractice cases, the deadline is generally 2 ½ years from the last date of treatment with that provider. Please contact my office if you have any questions about what deadlines apply to your case.
