How do I know whether I have a personal injury claim?

A potential claim may exist when another person, business, property owner, contractor, medical provider, or other party contributed to an injury through negligent or wrongful conduct. An attorney must evaluate responsibility, medical causation, damages, available insurance, and any defenses before determining whether a viable case exists.

Can more than one party be responsible for the same injury?

Yes. A single incident may involve several responsible parties, such as a negligent driver and vehicle owner, a property owner and maintenance contractor, or multiple companies involved in a construction project. Identifying every potentially responsible party is important because each may possess different evidence, insurance coverage, and legal obligations.

Can I recover compensation if I was partly responsible for the accident?

Potentially. In most New York personal injury cases, a claimant's percentage of fault reduces the damages recoverable rather than automatically eliminating the claim. A different rule now applies to certain motor-vehicle personal injury actions subject to Insurance Law Article 51, where recovery may be barred if the claimant is more at fault than the defendant or the combined defendants. The applicable rule depends on the type and timing of the case.

Common Questions

Nassau County Personal Injury FAQ

How much does a personal injury lawyer cost in Nassau County?

We work on a contingency fee — there’s no upfront cost and no fee unless we recover compensation for you. Clients may be responsible for case-related expenses.

Do I have a personal injury case?

If you were injured because of someone else’s negligence — in a crash, on a job site, on unsafe property, or through medical error — you may have a claim. The clearest way to find out is a free consultation to review the facts.

How long do I have to file a personal injury claim in New York?

New York generally allows three years from the date of injury for most personal injury claims, and two years for wrongful death — but shorter deadlines apply in some cases, such as claims against a government entity. Speak with an attorney promptly so deadlines aren’t missed.

What areas do you serve?

Case value depends on more than the initial medical bills. The analysis may include the severity and permanence of the injuries, treatment history, lost income, reduced earning capacity, future care, daily limitations, pain and suffering, liability evidence, and available insurance coverage.
