Third-Party Work Injury Claims in Massachusetts (Section 15)
If someone other than your employer caused or contributed to your on-the-job injury in Massachusetts, you may be able to bring a separate personal injury lawsuit against that party — on top of your workers’ compensation benefits. At Shea Culgin Law, attorneys Robert Shea and Joseph Culgin bring more than 40 years of combined experience handling both the workers’ comp claim and the third-party case across Brockton, Plymouth County, and all of southeastern Massachusetts — a combination that can dramatically increase a worker’s total recovery.
This matters because workers’ compensation, by design, is limited. It pays a percentage of your wages and your medical bills, but it does not pay for pain and suffering, loss of enjoyment of life, or full lost earnings. A third-party negligence claim can. The right to pursue it is preserved by Massachusetts General Laws Chapter 152, Section 15, which governs how a work injury caused by a non-employer is handled alongside the comp claim.
These cases are powerful but technically complex — especially the workers’ comp insurer’s lien on your third-party recovery. Contact Shea Culgin Law today for a free consultation or call our Brockton office at 508-510-5107.

What Is a Third-Party Work Injury Claim?
A third-party claim is a personal injury lawsuit against someone other than your employer or a co-worker whose negligence caused or contributed to your work injury. You pursue it in court, separately from — and in addition to — your workers’ compensation claim through the Department of Industrial Accidents.
The key is that workers’ compensation is generally your exclusive remedy against your employer (you cannot sue your employer for negligence), but it does not bar a claim against a negligent third party. So when a stranger to the employment relationship causes your injury, two separate avenues of recovery open up at once.
Why It Matters: Workers’ Comp vs. a Third-Party Case
The two claims compensate very different things:
- Workers’ compensation pays: a percentage of lost wages (60–66.67%), reasonable and necessary medical treatment, and certain specific benefits — regardless of fault, but with no payment for pain and suffering.
- A third-party negligence claim pays: your full lost earnings, pain and suffering, emotional distress, loss of enjoyment of life, loss of consortium for your spouse, and other damages not available in comp — but only if you can prove the third party was negligent.
For a seriously injured worker, the third-party case is often where the bulk of the real compensation lies. Pursued together and coordinated correctly, the comp claim provides immediate, no-fault support while the third-party case pursues full damages.
Common Third Parties in Work Injury Cases
Third-party liability arises constantly on Massachusetts jobsites and routes. Common examples include:
- A negligent driver who hits you while you are driving or working for your job — one of the most common third-party scenarios. (See our car accident and truck accident pages.)
- A manufacturer of defective equipment or machinery — a malfunctioning press, saw, ladder, scaffold, or safety device — under product liability law.
- A general contractor or another subcontractor on a construction site whose negligence injured you, when they are not your direct employer.
- A property owner who failed to maintain safe premises where you were working.
- A negligent maintenance company responsible for equipment or the worksite.
The Workers’ Comp Lien Under Section 15
This is the part workers most need a lawyer for. Under MGL Chapter 152, Section 15, the workers’ compensation insurer that paid you benefits has a lien on your third-party recovery. In plain terms, if you win or settle the third-party case, the comp insurer is generally entitled to be reimbursed out of that recovery for the benefits it paid.
Two critical points:
- Settlement approval is required. A third-party settlement that affects the comp lien generally must be approved by a court or, in some circumstances, by the Department of Industrial Accidents — and the lien must be addressed.
- The lien is negotiable. The amount the insurer recovers is frequently reduced — for the insurer’s share of attorney’s fees and costs, and through negotiation — so that more of the recovery stays with you. Skilled handling of the lien can be worth tens of thousands of dollars to an injured worker.
Coordinating the timing of the comp claim and the third-party case, and structuring the settlement to minimize the lien’s bite, is precisely where experienced counsel adds the most value.
Your Employer’s Immunity — and Its Limits
The general rule is that workers’ compensation is your exclusive remedy against your employer: in exchange for no-fault benefits, you ordinarily cannot sue your employer in tort. But there are important nuances:
- Co-employees acting within the scope of employment generally share the employer’s immunity.
- Separate entities are fair game. A parent company, a property owner, a different subcontractor, or an equipment manufacturer is not your employer and can be sued.
- Serious and willful misconduct. Where an employer’s serious and willful misconduct causes injury, MGL Chapter 152, Section 28 can allow double compensation — an enhanced comp remedy.
- Uninsured employers. If an employer illegally failed to carry workers’ comp insurance, different rules apply, and additional remedies — including the state’s Workers’ Compensation Trust Fund — may come into play.
Determining who can and cannot be sued requires sorting out the corporate and contractual relationships on the jobsite — something we investigate at the outset of every work-injury case.
Deadlines
- Third-party personal injury lawsuit: generally three years from the date of injury, under MGL Chapter 260, Section 2A — a different, often shorter clock than the workers’ comp claim.
- Workers’ compensation claim: generally four years from awareness of the work connection (MGL Chapter 152, Section 41).
Because the third-party deadline can run sooner, it is important to identify potential third-party defendants early. Waiting can forfeit the larger of your two potential recoveries.
Why You Need a Lawyer Who Handles Both Claims
The greatest value comes from handling the workers’ comp claim and the third-party case together, under one roof:
- Identifying every potentially negligent third party at the outset
- Keeping the comp benefits flowing while the third-party case develops
- Proving the third party’s negligence to recover pain and suffering and full lost earnings
- Negotiating down the Section 15 lien so more of the recovery stays with you
- Securing the required settlement approvals and coordinating the two cases so they reinforce rather than undercut each other
At Shea Culgin Law, our firm handles both the workers’ compensation and the personal injury sides of work-injury cases, so nothing falls through the cracks. We serve injured workers throughout Brockton, Plymouth County, and southeastern Massachusetts.
Frequently Asked Questions About Third-Party Work Injury Claims in Massachusetts
Can I sue someone for a work injury and still collect workers’ comp?
Yes. Workers’ compensation is generally your exclusive remedy against your employer, but it does not bar a lawsuit against a negligent third party — someone other than your employer or a co-worker. You can collect no-fault comp benefits and pursue a separate third-party negligence claim at the same time. The comp insurer will have a lien on the third-party recovery under MGL Chapter 152, Section 15.
Why bring a third-party claim if I already have workers’ comp?
Because workers’ comp does not pay for pain and suffering, loss of enjoyment of life, or your full lost wages — only 60–66.67% of wages plus medical benefits. A third-party negligence claim can recover those additional damages, and for a seriously injured worker it is often where most of the real compensation comes from.
What is the workers’ comp lien?
Under MGL Chapter 152, Section 15, the insurer that paid your comp benefits has a lien on your third-party recovery — meaning it is generally entitled to be reimbursed from your settlement or verdict for what it paid. The lien is negotiable and is typically reduced for the insurer’s share of attorney’s fees and costs, so experienced handling can keep more of the recovery in your pocket. Third-party settlements affecting the lien generally require court or DIA approval.
Can I sue my employer directly for a work injury?
Generally no — workers’ compensation is the exclusive remedy against your employer, so you ordinarily cannot sue your employer for negligence. Exceptions exist, including the employer’s serious and willful misconduct (which can allow double compensation under Section 28) and an employer that illegally failed to carry comp insurance. But you can sue separate third parties such as equipment manufacturers, other contractors, property owners, or negligent drivers.
How long do I have to file a third-party work injury lawsuit?
Generally three years from the date of injury under MGL Chapter 260, Section 2A — a separate and often shorter deadline than the four-year workers’ comp claim period. Because the third-party clock can run out sooner, it is important to identify potential third-party defendants early.
What are common examples of third-party work injury cases?
A negligent driver who hits you while you are working or driving for the job; a manufacturer of defective machinery, tools, ladders, or safety equipment; a general contractor or another subcontractor on a construction site who is not your employer; a property owner who failed to keep the premises safe; and negligent maintenance companies. Each is a non-employer who can be held liable in addition to your comp claim.
Injured at Work by Someone Other Than Your Employer? You May Have Two Claims.
A third-party case can recover the pain and suffering and full lost wages that workers’ comp leaves on the table. The attorneys at Shea Culgin Law handle both sides — and have spent over 40 years maximizing recoveries for injured workers in Brockton and across Massachusetts.
