Key Takeaways
- You can file a third-party claim if someone other than your employer caused your workplace injury, allowing you to pursue compensation beyond standard workers’ compensation benefits.
- Third-party claims differ from workers’ comp because they require proving negligence. Still, they may allow recovery for full lost wages, pain and suffering, and other damages not covered by workers’ compensation.
- Common third parties include contractors, property owners, equipment manufacturers, and negligent drivers, especially in construction accidents, defective equipment cases, slip-and-fall cases, and work-related car accidents.
- You can pursue both workers’ compensation and a third-party lawsuit at the same time, but strict deadlines apply under N.Y. CPLR § 214, and workers’ comp insurers may have a lien on any third-party settlement.
Yes, you can seek compensation for a workplace injury from a third party if someone other than your employer caused your injury. This is done through a third-party claim that is separate from a workers' compensation claim under the workers' compensation system, which means you may have more legal options to recover damages beyond workers' comp benefits.

What Is a Third-Party Workplace Injury Claim?
A third-party claim is a personal injury claim filed against an outside company or person who is not your employer but whose actions caused your workplace injury, and this type of third-party liability allows injured workers to seek compensation beyond what workers' compensation benefits provide. These claims focus on fault and wrongdoing.
How It Differs From Workers’ Compensation
Workers' compensation is a no-fault system that provides basic benefits such as medical expenses and lost wages, even if no one is clearly at fault, while a third-party claim is based on negligence or wrongdoing, which means you must prove fault and show that the other party's negligence caused your injuries and damages.
Who Can Be a Third Party in a Workplace Injury Case?
In many workplace injury cases, a third-party can be any person or business that is not your employer but whose actions caused or contributed to your injuries, and these third-party liability claims often arise when an outside company, contractor, or negligent driver is involved in the accident.
Identifying the at-fault party is very important.
Contractors or Subcontractors
Contractors or subcontractors on construction sites may be held liable if their unsafe actions or failure to follow safety rules caused a workplace accident or construction site accident. These parties are often responsible for specific tasks and must follow safety standards at all times.
If they fail to do so, they may be held responsible for injuries caused. Their role in the project can be closely reviewed to prove fault.
Property Owners (Premises Liability)
A property owner may be responsible under premises liability if they failed to maintain a safe environment, and that failure caused your work injury. This includes failing to fix hazards or warn about dangerous conditions. Property owners must keep areas safe for workers and visitors. If they ignore risks, they may be held liable.
Equipment or Machinery Manufacturers
Manufacturers may be held responsible if defective equipment, a defective tool, or a design or manufacturing defect caused your injuries. These cases often involve unsafe products that fail during normal use. A manufacturing defect or design issue can lead to serious harm. The manufacturer may be held responsible for these failures.
Drivers in Work-Related Vehicle Accidents
A negligent driver or at-fault driver in motor vehicle accidents or a car accident caused during work, such as a delivery driver incident, may be liable for your injuries. These accidents can happen during job duties or travel between work sites. The at-fault party may be another driver or company. Proving fault is important in these cases.

Common Situations Where Third-Party Claims Apply
There are many common examples of third-party claims work situations where injured workers can file a third-party lawsuit, especially when an outside company or another party’s negligence contributed to the workplace accident. These situations often involve unsafe conditions, defective products, or motor vehicle accidents.
Construction Site Accidents
Construction site accidents often involve multiple parties, and a contractor or outside company may be held liable for unsafe work conditions or safety violations. These cases can be complex and require careful review.
Defective Equipment or Machinery
If defective equipment or a manufacturing defect caused your injury, the manufacturer or distributor may be held responsible. These claims often involve product liability laws.
Slip and Fall on Someone Else’s Property
A slip-and-fall on someone else's property may lead to a premises liability claim if the property owner failed to fix hazards. This can include unsafe floors or poor maintenance.
Car Accidents While Working
A car accident caused by another driver while you are working may allow you to file a third-party claim against the at-fault driver. These cases often involve insurance claims and liability issues.
Laws That May Apply to Third-Party Claims
Several laws apply to third-party claims, including general negligence and workers' compensation laws, which help determine how injured workers can pursue compensation and who may be held liable. Understanding these laws helps protect your rights.
Negligence Laws (General Personal Injury Principles)
Negligence laws require you to prove negligence by showing that the other party failed to act reasonably and that this party’s breach caused your injuries.
Workers’ Compensation Laws
Under N.Y. Workers’ Comp Law § 29, injured employees who receive workers' compensation benefits can still file a third-party claim and pursue additional compensation from the at-fault party.
Product Liability Laws
Product liability laws apply when defective equipment, toxic substances, or unsafe products cause injuries due to a design or manufacturing defect.
What Compensation Can You Recover From a Third Party?
A third-party claim allows injured workers to seek compensation that goes beyond workers' comp benefits, including full lost wages, pain and suffering, and other damages not covered by workers' compensation insurance. These claims can result in more compensation and a larger recovery.
Medical Expenses
You can recover medical expenses and medical bills related to your injury, including treatment, hospital care, and future care costs. These costs can add up quickly.
Lost Wages and Future Earnings
You may recover lost wages, lost income, and even full lost wages if your injury affects your ability to work in the future. This helps support your financial stability.
Pain and Suffering
You can seek compensation for physical pain, emotional distress, and the overall impact of the injury on your life. These damages reflect personal losses.
Disability and Long-Term Care Costs
You may recover costs for long-term care, disability, and ongoing medical needs if your injury leads to lasting harm. This helps cover future care needs.

Can You File Both Workers’ Comp and a Third-Party Claim?
Many injured workers ask if they can receive workers' compensation benefits and still file a third-party lawsuit, and the answer is yes in most cases, as long as another party’s negligence contributed to the accident. These claims often work together.
Yes, You Can Pursue Both Claims
You can receive workers' comp benefits through a workers' compensation claim and still pursue compensation through a third-party claim at the same time.
How the Claims Work Together
The workers' compensation insurer may cover initial costs, while the third-party claim seeks additional compensation from the at-fault party.
Workers’ Comp Lien and Reimbursement
The workers' compensation insurance carrier may place a lien on your third-party settlement to recover what it paid, which helps avoid double recovery.
How to Prove a Third-Party Claim
To succeed in a third-party claim, you must prove fault by showing that the other party’s negligence caused your workplace injury, and this requires strong evidence and a clear legal strategy. Proving fault is key to your case.
Establishing Negligence
You must show that the party failed to act safely and that this party’s negligence contributed to your injuries and damages.
Gathering Evidence
Strong evidence is needed to prove negligence and support your personal injury claim.
Some of the key evidence you may use includes:
- Accident reports and workplace records
- Medical documentation and medical bills
- Witness statements from a co-worker or other workers
- Photos or videos of the accident scene
- Proof of defective equipment or unsafe conditions
Using Expert Testimony
Experts may help explain how the accident occurred, prove fault, and show that the injuries resulted from the other party’s breach.
Statute of Limitations for Third-Party Claims
There are strict deadlines for filing a third-party lawsuit, and missing these deadlines can affect your ability to seek compensation and pursue your claim. Acting early is very important.
Personal Injury Deadline
Under N.Y. CPLR § 214, you generally have 3 years to file a personal injury lawsuit from the date of the workplace injury.
Shorter Deadlines for Government Claims
If your claim involves a government entity, you must file a notice of claim within 90 days, which is a much shorter deadline.
