1. What New York Courts Require to Prove Negligence
New York law requires a plaintiff to establish four specific elements to succeed in any personal injury claim. A gap in any one of them can defeat an otherwise strong case, regardless of how clear the other party's fault may appear.
- Duty of care: The defendant owed a legal obligation to act with reasonable care toward the plaintiff.
- Breach: The defendant's conduct fell below the standard a reasonable person would have followed under the same circumstances.
- Causation: The breach was both the actual ("but-for") cause and the proximate (foreseeable) cause of the injury.
- Damages: The plaintiff suffered measurable harm as a direct result of the breach.
Duty, Breach, and the Reasonable Person Standard
Duty arises from the relationship between the parties: a property owner owes a duty to maintain safe conditions, a driver owes a duty to operate a vehicle with reasonable care, and an employer owes a duty to provide a safe workplace. Courts evaluate breach against the specific facts of the incident, not a generalized standard, which is why scene photographs, witness statements, and physical measurements taken immediately after the event are critical. My firm dispatches investigators quickly to document conditions before they change, because that early record often becomes the foundation of the entire claim.
Causation, Foreseeability, and the Eggshell Plaintiff Doctrine
Proving causation requires two showings: the breach must be the actual cause of the injury, and the injury must have been a foreseeable consequence of the breach. New York also follows the eggshell plaintiff doctrine, meaning a defendant who triggers a severe injury in a person with a pre-existing condition cannot reduce liability by pointing to that vulnerability. Insurance carriers routinely attempt to attribute severity to prior injuries, so building a clear medical baseline early is one of the most important steps an attorney takes to protect the client's full recovery.
2. How New York'S Pure Comparative Fault Rule Affects Recovery
Unlike many states that bar recovery once a plaintiff exceeds 50 percent fault, New York follows pure comparative negligence under CPLR Article 14-A, Section 1411. Every percentage point of assigned fault directly reduces the final award, so challenging the fault allocation is as important as proving the initial negligence.
| Plaintiff's Assigned Fault | Total Damages | Recoverable Amount |
| 0% | $500,000 | $500,000 |
| 20% | $500,000 | $400,000 |
| 50% | $500,000 | $250,000 |
| 80% | $500,000 | $100,000 |
Figures are illustrative only.
Insurance adjusters collect early recorded statements specifically to build a narrative of shared fault, and I have seen those statements used to inflate a client's assigned percentage far beyond what the evidence supported. Never provide a recorded statement to any opposing insurer without first speaking with an attorney.
3. New York Statutory Deadlines
Missing a filing deadline in New York permanently ends any right to recovery, regardless of injury severity or how clearly the other party was at fault.
| Claim Type | Statute | Deadline |
| Most personal injury | CPLR §214(5) | 3 years from incident date |
| Wrongful death | EPTL §5-4.1 | 2 years from date of death |
| Medical malpractice | CPLR §214-a | 2 years and 6 months |
| Government entity (Notice of Claim) | GML §50-e | 90 days from incident |
| Government entity (lawsuit) | GML §50-i | 1 year and 90 days |
What the 90-Day Government Notice Requirement Means in Practice
When a municipality, transit authority, public school district, or other government-operated entity contributed to the injury, General Municipal Law Section 50-e requires a formal Notice of Claim within 90 days of the incident. The notice must identify the claimant, describe the nature of the claim, and specify the time, date, and location with reasonable accuracy. Courts rarely grant late-notice applications, so evaluating government entity involvement is one of the first steps taken after any accident on public property or involving a public vehicle.
4. Building the Evidence Record New York Courts Require
The strength of a New York injury case depends almost entirely on what is documented in the first 72 hours. Evidence that is not secured immediately is often gone permanently.
- Police reports: Provide a contemporaneous official account and identify witnesses whose recollections become critical months later.
- Medical records: Establish the causal link between the incident and the injuries; gaps in treatment are used by defense attorneys to argue the injuries were minor or unrelated to the accident.
- Photographs and video: Surveillance footage from commercial properties and traffic cameras is typically overwritten within 72 hours; a litigation hold letter must be served before that window closes.
- Accident reconstruction: Reconstructionists analyze vehicle data, skid marks, and impact geometry to establish speed, braking behavior, and fault allocation in complex cases.
- Expert medical testimony: Connects clinical findings to the mechanism of injury, countering defense arguments that pre-existing conditions caused the documented harm.
I have seen cases turn entirely on surveillance footage that would have been deleted within days had we not served a preservation demand immediately after the client called.
5. From Investigation to Resolution
Most New York personal injury cases settle before trial, but every case must be prepared as though it will go before a jury, because settlement offers track the opposing side's assessment of jury value. Non-economic damages, including pain and suffering and loss of enjoyment of life, carry no statutory cap in New York personal injury cases, which means the quality of the narrative built around the client's daily losses matters as much as the medical bills.
What "Full Damages" Means in New York
- Past and future medical expenses
- Lost wages and reduced earning capacity
- Life care plan costs (surgery, rehabilitation, assistive equipment, home modifications)
- Pain and suffering
- Emotional distress
- Loss of enjoyment of life
When direct negotiation stalls, mediation provides a structured alternative: a neutral third party facilitates discussion without binding either side unless a written agreement is reached, and the option to proceed to trial remains fully open if the process fails. I evaluate every settlement offer against the complete damages picture, including projected future care costs, before advising clients whether to accept or continue toward trial.
