ToggleWe've Recovered Over 200 Million Dollars for Our Clients.
A workplace injury is hard enough. When someone other than your employer caused it, you may be entitled to far more than workers’ compensation alone can provide. If a contractor, equipment manufacturer, or another party’s negligence put you in harm’s way, Pennsylvania law gives you the right to pursue both workers’ compensation benefits and a separate third-party personal injury claim at the same time.
New Castle workers’ compensation lawyers Joseph A. George and Lawrence M. Kelly of Luxenberg Garbett Kelly & George P.C. represent injured workers across New Castle, Lawrence County, and Western Pennsylvania. The firm has over 90 years of combined experience in personal injury litigation. When it comes to third-party liability claims, the difference between recovering workers’ comp benefits alone and pursuing every available claim can be tens of thousands of dollars.
This guide explains what a third-party liability claim is, who qualifies as a third party, what types of compensation are available, how subrogation works, how the filing process unfolds, and how much time you have to act. Call Luxenberg Garbett Kelly & George P.C. at (724) 658-8535 to schedule a free consultation about your workers’ compensation claim and any potential third-party case.

Lawyers Are Standing By
A third-party liability claim is a personal injury lawsuit filed against someone other than your employer whose negligence caused or contributed to your workplace injury. Under Pennsylvania workers’ compensation law, you generally cannot sue your employer directly; workers’ comp is your exclusive remedy against them. However, that protection does not extend to outside parties whose negligence harmed you.
In most cases, a “third party” is someone other than your employer or a co-worker, such as another contractor, a property owner, a driver, or a product manufacturer. When a third party’s actions or failures caused your accident, Pennsylvania law allows you to pursue a separate civil claim for damages that workers’ compensation does not cover.
Third-party claims are governed by Pennsylvania’s personal injury statutes, not the Workers’ Compensation Act. As a result, the types of compensation available, the standard of proof required, and the timeline for filing are all different from what applies to a workers’ comp claim.
Key Takeaway: Pennsylvania workers’ compensation is your exclusive remedy for injuries caused by your employer’s negligence, but it does not protect third parties who contributed to your injury. A third-party claim is filed alongside, not instead of, your workers’ comp claim.
Contact Joseph A. George of Luxenberg Garbett Kelly & George P.C. to evaluate whether a third-party claim applies to your situation. Call (724) 658-8535 today for a free consultation.
Third parties responsible for workplace injuries in Pennsylvania fall into several well-established categories. Identifying the right parties is one of the most important tasks in any third-party case, and it requires careful investigation of who was on-site, what equipment was used, and what caused the accident.
Common third parties in work injury cases include:
Key Takeaway: Any individual or company that is not your employer – including equipment makers, site owners, contractors, or drivers – can be a third party whose negligence gives rise to a separate civil claim alongside workers’ compensation.
Luxenberg Garbett Kelly & George P.C. handles cases involving third-party defendants throughout Lawrence County, Allegheny County, Butler County, and the surrounding region. Call (724) 658-8535 to discuss who may be responsible for your injuries.

Workers’ compensation in Pennsylvania covers a limited range of losses: medical expenses and a portion of your lost wages. It does not compensate you for pain and suffering, emotional distress, loss of enjoyment of life, or the full scope of your lost earning capacity. A third-party civil lawsuit can recover all of these.
| Category of Compensation | Workers' Compensation | Third-Party Civil Claim |
|---|---|---|
| Medical expenses | Yes (covered) | Yes (can be claimed) |
| Lost wages (partial) | Yes, generally about two-thirds of your average weekly wage | Yes (full wage loss) |
| Pain and suffering | No | Yes |
| Emotional distress | No | Yes (often as part of pain and suffering, when supported) |
| Permanent disfigurement | Limited | Yes |
| Loss of consortium (spouse) | No | Yes |
| Punitive damages | No | Possible in rare cases (e.g., reckless or outrageous conduct) |
The ability to recover non-economic damages, particularly pain and suffering, is one of the most significant advantages of a third-party claim. A serious workplace injury in New Castle or Lawrence County can affect your quality of life for years. Workers’ compensation alone rarely reflects that full impact.
Key Takeaway: Workers’ compensation covers basic medical costs and partial wage replacement. A third-party claim can recover your full wage loss, pain and suffering, emotional damages, and more, making the combined recovery substantially larger in serious injury cases.
Joseph A. George of Luxenberg Garbett Kelly & George P.C. can evaluate the full value of your claims in both legal tracks. Call (724) 658-8535 for a free case review.
Not every work injury involves a third party, but certain types of accidents almost always raise the question. If you were hurt in any of the following situations, a third-party claim may be available alongside your workers’ compensation claim.
Lawrence County’s industrial history means that workers in New Castle and surrounding areas often work on job sites with multiple employers, contractors, and vendors present. When one company’s employees or equipment injures a worker from a different company, a third-party claim is likely. Construction remains a high-risk industry in Pennsylvania. In 2023, the construction sector had the highest number of workplace fatalities in the state. OSHA also identifies falls, struck-by incidents, caught-in/between hazards, and electrocutions as the ‘Focus Four’ construction hazards.
Common third-party scenarios on work sites include:
If you drive as part of your job, including deliveries, service calls, or travel between job sites, and another driver causes an accident, that driver is almost certainly a third party. This is one of the most straightforward third-party situations. Your employer’s workers’ compensation carrier covers your medical expenses and partial wages. At the same time, the at-fault driver’s auto insurance (and potentially your own underinsured motorist coverage) becomes the source of additional recovery.
Workers who use tools, machinery, and industrial equipment on the job face risks when those products are defectively designed or manufactured. Under Pennsylvania product liability law, a manufacturer can be held responsible for injuries caused by a defective product regardless of whether the manufacturer acted carelessly. If the product was unreasonably dangerous, liability may attach. This includes hand tools, power equipment, safety gear, chemical products, and industrial machinery.
Key Takeaway: Construction accidents involving multiple contractors, on-the-job vehicle crashes, and defective equipment failures are three of the most common sources of third-party liability claims for Pennsylvania workers.

We only work with clients and cases we truly believe in, we take your case because we genuinely believe in both you and your case’s importance.
When you receive both workers’ compensation benefits and a third-party settlement, Pennsylvania law requires coordination between those two recoveries through a process called subrogation. Under 77 P.S. § 671 of the Pennsylvania Workers’ Compensation Act, your employer’s workers’ compensation carrier acquires a right to be reimbursed from your third-party recovery for the benefits they already paid.
Subrogation works as follows: if your employer’s insurer paid $50,000 in workers’ comp benefits, and you later recover $150,000 from a third-party lawsuit, the insurer typically asserts a subrogation lien against the third-party recovery for benefits already paid, subject to a pro-rata share of attorney’s fees and costs. However, the law also requires that attorneys’ fees and legal costs be prorated between you and the insurer, reducing the lien proportionally.
Handling both a workers’ compensation claim and a third-party lawsuit simultaneously is legally complicated, and the interaction between them directly affects how much money you ultimately keep. An attorney who handles only workers’ comp cases, or only personal injury cases, may not understand how to properly negotiate subrogation liens, structure settlements, or argue that the lien should be reduced based on the facts of the case.
Insurers have a statutory right to reimbursement, but they cannot force you to file a third-party lawsuit on their behalf. Pennsylvania appellate courts have held that an employer/insurer generally cannot bring a direct action against the third-party tortfeasor solely to recover its subrogation lien. In practice, the injured worker usually controls whether a third-party lawsuit is filed.
Key Takeaway: Pennsylvania’s subrogation law requires your workers’ comp insurer to be reimbursed from your third-party settlement, but attorney’s fees are prorated, and the lien can sometimes be negotiated downward. Coordinating both claims requires an attorney who handles both types of cases.
Lawrence M. Kelly and Joseph A. George of Luxenberg Garbett Kelly & George P.C. handle both workers’ compensation and personal injury claims in-house. Call (724) 658-8535 to discuss how subrogation may affect your recovery.
Pennsylvania law sets firm deadlines for third-party claims, and missing them can permanently eliminate your right to additional compensation. In most workplace injury cases, the two-year deadline to file a third-party lawsuit starts on the date of injury. Limited exceptions can apply in certain circumstances, so it’s safest to treat the injury date as the starting point and act quickly.
Additionally, physical evidence disappears quickly on work sites. Employers and other defendants often clear accident scenes rapidly, and surveillance footage, if any exists, is typically overwritten within days or weeks. Witness memories also fade. For these reasons, reaching out to an attorney as early as possible after a workplace injury gives your legal team the best chance to preserve evidence before it is gone.
If the potential defendant is a government unit, Pennsylvania law generally requires written notice within six months of the injury (with specific content and service requirements).
Key Takeaway: Pennsylvania law gives injured workers two years from the date of a workplace accident to file a third-party civil lawsuit. Acting promptly protects both the legal deadline and the physical evidence needed to support your claim.
Filing a third-party claim alongside a workers’ compensation case involves a multi-stage process.
Immediately after a workplace accident, report your injury to your employer and seek medical attention. Pennsylvania law requires injury reporting within 120 days, and your workers’ compensation claim must be filed within three years of the injury. Accepting workers’ compensation benefits does not prevent you from filing a third-party claim.
An experienced attorney will investigate the circumstances of your accident to identify every party whose negligence may have contributed. This may involve reviewing safety records, inspecting the accident scene, obtaining witness statements, and consulting with experts in engineering, product safety, or workplace safety standards.
Work sites in New Castle and throughout Western Pennsylvania are often cleaned up, modified, or rebuilt quickly after an accident. Your attorney should take immediate steps to preserve physical evidence, request that employers and third parties preserve surveillance footage, and document conditions before they change.
A personal injury lawsuit is filed in the appropriate Pennsylvania court. Depending on the facts, the Lawrence County Court of Common Pleas may be the proper venue for a third-party lawsuit. Cases involving large commercial defendants or federal questions may proceed in the U.S. District Court for the Western District of Pennsylvania.
Third-party cases typically involve depositions, document requests, and expert witnesses. In product liability cases, engineering experts may testify about defective design. In construction accident cases, workplace safety experts may evaluate Occupational Safety and Health Administration (OSHA) compliance and standard industry practices.
Most third-party cases resolve through negotiated settlements. When settlement is not appropriate, the attorneys at Luxenberg Garbett Kelly & George P.C. are prepared to take cases to trial. Lawrence M. Kelly has been named to the Pennsylvania Super Lawyers list continuously since 2006, has earned the Champion of Justice award from the Western Pennsylvania Trial Lawyers Association, and is Board Certified as a Civil Trial Specialist.
Key Takeaway: Third-party claims involve investigation, evidence preservation, litigation, and negotiation, all while a parallel workers’ compensation case proceeds. An attorney who understands both systems can coordinate a strategy to maximize your total recovery.
Our Family is Here to Help Yours
A workplace injury is already disruptive – and finding out that a third party’s negligence caused it can leave you with questions about what to do next. Workers’ compensation will cover some of your losses, but Pennsylvania law may entitle you to far more through a separate civil claim. The key is acting quickly and working with attorneys who understand both legal systems.

George of Luxenberg Garbett Kelly & George P.C. represent injured workers throughout New Castle, Ellwood City, and Lawrence County in both workers’ compensation proceedings and third-party personal injury cases.

Yes. Pennsylvania law allows injured workers to pursue both a workers’ compensation claim and a third-party civil lawsuit simultaneously. Accepting workers’ compensation benefits does not waive your right to sue a negligent third party. The two claims run in parallel, though the subrogation lien from your workers’ comp carrier will apply to any third-party recovery.
Pennsylvania follows a modified comparative negligence rule. Under this standard, you can recover damages as long as your share of fault is not greater than the combined fault of the defendant(s), though your recovery is reduced by your percentage of fault. If you are found to be 30 percent at fault, your total recovery would be reduced by 30 percent. Workers’ compensation, by contrast, is a no-fault system. Your own negligence does not affect your eligibility for workers’ comp benefits.
Generally, no. Pennsylvania workers’ compensation law grants fellow employees immunity from personal injury lawsuits for work-related injuries, with very limited exceptions. The immunity does not extend to third parties who are not employed by your employer.
If the third party is uninsured or underinsured, your own employer’s workers’ compensation policy still covers your medical expenses and lost wages. Additionally, if a vehicle was involved, your employer’s commercial auto policy or your personal underinsured motorist coverage may provide additional recovery. An attorney can evaluate all available sources of compensation.
Most third-party cases take between one and three years to resolve, depending on the complexity of the case, the seriousness of the injuries, and whether the matter goes to trial. Cases involving catastrophic injuries, disputed liability, or multiple defendants typically take longer than straightforward vehicle accident cases.
Filing a third-party lawsuit does not reduce or eliminate your workers’ compensation benefits. However, if your third-party case results in a settlement or verdict, your employer’s workers’ compensation insurer has a right to be reimbursed for benefits already paid, under the subrogation provisions of the Pennsylvania Workers’ Compensation Act. Your attorney can negotiate to reduce the amount of the lien.
