Carelessness alone does not win a case. New York makes an injured person prove specific things before anyone has to pay. Lawyers call that proof "negligence."
The rules are learnable. Four elements decide liability, deadlines decide whether you can file at all and a fault rule decides what happens when you share some blame.
Here is each piece in plain terms: what you must prove, how your own fault changes the math, and why the calendar matters more than people expect.
The Four Elements of Negligence
Every New York negligence case rests on four elements.
First, duty. The other party owed you a legal obligation to use reasonable care. A driver owes that duty to everyone on the road. A store owner owes it to customers. A property owner owes it to visitors.
Second, breach. The party failed to meet that duty. Running a red light is a breach. So is leaving a spill on a supermarket floor for an hour.
Third, causation. The breach actually caused your injury. Many cases turn on this element. The defense will blame your back problem on age, a prior accident, or anything except the collision. Your treating physicians' independent findings, built into the medical record, answer that argument.
Fourth, damages. You suffered real harm. The main categories are medical bills, lost wages, and pain and suffering. Without measurable harm there is no case, even against an obviously careless defendant.
Every element needs evidence. Photographs, witness statements, records, and consistent medical documentation carry the proof. A true story without support loses to a documented one.
Shared Fault: Two Different Rules in New York
Being partly at fault does not automatically end a case. The rule depends on the type of case.
For motor vehicle cases, CPLR § 1411 now sets a modified comparative fault rule under subsection (b). You recover nothing if your share of fault exceeds the combined fault of the parties you are suing. If it does not, you recover, reduced by your percentage. A driver found 30 percent at fault with $100,000 in damages recovers $70,000. This rule applies to actions started on or after May 26, 2026.
Outside the motor vehicle system, pure comparative fault under CPLR § 1411(a) still governs. A fall on someone's property or a construction injury follows that rule. Partial fault reduces recovery but never bars it, whatever the percentage.
Two more car-case wrinkles. Under Insurance Law § 5104, the jury must decide fault before deciding whether the injury qualifies as serious. A separate provision also caps non-economic damages at $100,000 for certain at-fault injured people, such as a driver who was required to insure the vehicle and did not.
The Serious Injury Threshold in Car Accident Cases
Proving negligence is step one in a crash case, not the finish line. New York restricts the right to sue for pain and suffering after a motor vehicle accident. You must show a serious injury as defined in Insurance Law § 5102.
Under current law, the qualifying categories are: death, dismemberment, significant disfigurement, fracture, loss of a fetus, permanent loss of use of a body organ, member, function or system, permanent consequential limitation of use of a body organ or member, and significant limitation of use of a body function or system.
Older articles describe a 90/180-day category based on disrupted daily activities. That category was repealed in New York's 2026 tort reform, and does not apply to newly filed cases.
The threshold is why early, steady medical treatment matters. These categories turn on what the record shows over time. Gaps in care make permanence or significant limitation harder to prove. If you were recently hit, our guide to the deadlines, calls, and offers coming your way covers the first weeks in detail.
The Deadlines That Control Everything
Strong claims can expire before anyone files them. Three deadlines control most cases.
The general statute of limitations for personal injury is three years from the accident under CPLR § 214. Wrongful death is shorter: two years under EPTL § 5-4.1.
After a car accident, the no-fault application must be filed within 30 days to preserve up to $50,000 in basic benefits. Those benefits include medical bills and wage replacement of 80 percent of earnings, up to $2,000 per month.
When a city, county, or state vehicle or property is involved, a Notice of Claim is generally due within 90 days under General Municipal Law § 50-e. That window closes while most people are still in treatment and have not considered a claim.
Work injuries follow their own rules. A hurt worker usually cannot sue the employer, but claims against owners and general contractors often remain. Those cases are explained on our construction accidents page and in our discussion of when you can sue beyond workers' comp.
How Insurers Evaluate a Negligence Claim
An adjuster works through the same four elements a jury would. The police report and witness accounts answer liability. The medical record answers causation and severity. Available coverage tells the company what is actually at stake.
That review starts early, often within days of the report. A statement given before the full picture is known can lock in a version of events that is hard to fix later. Gaps in treatment get read as proof the injury resolved. None of that is a trick. It is how claims are valued, and knowing it helps you decide what to say and when.
A claim with consistent documentation, prepared for trial, gets priced differently than one without. The work behind the file moves the number, not volume or noise.
How Schwartzapfel Holbrook Builds Negligence Cases
Schwartzapfel Holbrook is selective about the negligence cases it accepts across New York City, Nassau County, and Suffolk County. When we take a case, we investigate liability and damages fully before anyone offers an opinion on value. We identify every applicable policy. We follow the medical record as it develops through the treating physicians' independent findings. We prepare every case expecting it may need to be proven in a courtroom. That preparation is why most of our cases resolve without a trial, and why the ones that do not are ready for one.
