Third Party Workers’ Compensation Claims in Massachusetts
When you are injured at work, workers’ compensation provides important benefits — but it is not always your only legal remedy. In many workplace accidents, a third party (someone other than your employer) may also bear responsibility for your injuries. At Shea Culgin Law, our attorneys help injured workers in Brockton and throughout southeastern Massachusetts pursue both workers’ compensation benefits and third party personal injury claims to maximize their total recovery.
What Is a Third Party Workers’ Compensation Claim?
A third party claim is a personal injury lawsuit brought against a party other than your employer who contributed to your workplace injury. Unlike workers’ compensation — which is a no-fault system and does not allow you to sue your employer for negligence — a third party claim allows you to seek damages based on negligence and can result in significantly greater compensation.
Importantly, pursuing a third party claim does not affect your right to workers’ compensation benefits. You can receive both simultaneously, though Massachusetts law does require the workers’ compensation insurer to be reimbursed from any third party recovery.
Who Can Be a Third Party?
Common third parties in Massachusetts workplace injury cases include:
- Contractors and subcontractors: On construction sites and other worksites with multiple employers, a negligent contractor or subcontractor who is not your direct employer can be sued as a third party.
- Equipment and product manufacturers: If defective machinery, tools, or safety equipment caused or contributed to your injury, the manufacturer may be liable under product liability law.
- Property owners: If you were injured on someone else’s property due to hazardous conditions, the property owner may be liable under premises liability law.
- Negligent drivers: If your job involves driving and you were injured in a car accident caused by another driver, that driver and their insurance company can be sued.
- Staffing agencies: If you were placed by a staffing agency and injured due to conditions at the host employer’s site, the agency or host employer may be liable.
- Maintenance companies: Third-party maintenance or janitorial companies that created dangerous conditions may also be liable.
What Additional Damages Can You Recover in a Third Party Claim?
Workers’ compensation benefits are valuable but limited. They do not compensate you for pain and suffering, full lost wages, or loss of future earning capacity. A third party lawsuit can recover:
- Full lost wages — not just the 60% available through workers’ comp TTD benefits
- Pain and suffering — compensation for physical pain, emotional distress, and reduced quality of life
- Loss of consortium — damages for the impact on your relationship with your spouse
- Future medical expenses — all projected future care costs beyond what workers’ comp will cover
- Loss of future earning capacity — if your injuries prevent you from returning to your previous level of work
- Punitive damages — in rare cases involving particularly reckless conduct
The Relationship Between Workers’ Comp and Third Party Claims
When you receive workers’ compensation benefits and later recover from a third party, Massachusetts law gives the workers’ compensation insurer a lien on your third party recovery. This means the insurer has the right to be reimbursed from your lawsuit proceeds for the benefits already paid. Our attorneys carefully manage these liens to minimize their impact on your net recovery and ensure you keep as much compensation as possible.
Common Third Party Workplace Injury Scenarios
Construction Site Accidents
Construction sites are among the most dangerous workplaces in Massachusetts. When multiple contractors, subcontractors, and property owners are present, third party liability is common. Falls, equipment failures, and being struck by objects are frequent causes of serious construction injuries. See our page on construction injury claims for more information.
Motor Vehicle Accidents on the Job
Delivery drivers, sales representatives, and other workers who drive for their jobs are frequently injured by negligent motorists. If another driver caused the accident, you can file a workers’ compensation claim with your employer AND pursue a third party claim against the at-fault driver.

Defective Equipment Claims
Machinery and equipment that malfunctions due to a design defect, manufacturing defect, or failure to warn can result in catastrophic injuries. The equipment manufacturer, distributor, or seller may all be liable under Massachusetts product liability law.
