In New York, you have three years to file a car accident lawsuit. However, certain circumstances can shorten this deadline. For instance, if you’ve been injured due to the negligence of a municipality or someone working on behalf of a municipality, you must file a notice of claim within 90 days of the accident and then file a lawsuit within one year and 90 days. Additionally, if you are injured in a car accident in New York, you have a 30-day deadline to file with your insurance company to apply for no-fault insurance benefits. These benefits will cover your medical treatment and lost wages up to $50,000, and potentially more.
