Workers’ Comp Isn’t Always Enough: How a Third-Party Claim Can Recover What Your Employer’s Insurance Won’t Pay

Key Takeaways

When someone other than your employer or another immune party — a contractor, equipment manufacturer, property owner, or negligent driver — contributed to your workplace injury in South Carolina, you may be able to pursue a third-party lawsuit alongside your workers’ comp claim. A third-party workplace injury claim can recover damages workers’ comp never covers, including pain and suffering and the full value of lost wages. A South Carolina workplace injury lawyer can evaluate whether your situation supports a separate lawsuit and help you pursue every source of compensation available.

You got hurt at work. You filed a workers’ compensation claim and now you’re waiting — for the adjuster to call back, for the doctor visit to be approved, for the check that covers two-thirds of what you used to bring home. Workers’ comp does what it was designed to do, but it was never designed to do everything. If someone other than your employer caused or contributed to your injury, South Carolina law may give you a path to the compensation that workers’ comp leaves behind.

What Is a Third-Party Workplace Injury Claim?

Workers’ compensation is the exclusive remedy against your employer and certain other parties protected by workers’ comp immunity for a work-related injury. That means you generally cannot sue your employer directly, even if the company was careless. Workers’ comp pays regardless of fault — you don’t have to prove anyone did anything wrong to receive benefits — but it cannot compensate you for pain and suffering or replace the full value of your lost wages. As our FAQ on what South Carolina workers’ compensation covers explains, benefits are limited by design.

A third-party claim is different. It is a personal injury lawsuit filed against someone outside your employer — a company, a manufacturer, a property owner, or an at-fault driver — whose negligence played a role in your injury. If the defendant is not protected by workers’ comp immunity, the exclusivity rule does not apply. You can pursue both claims at the same time, and each follows its own procedural rules and deadlines.

Who Can Be Held Liable in a Third-Party Workplace Injury Claim?

South Carolina courts recognize a range of third parties whose negligence can give rise to a separate lawsuit after a workplace injury. Common defendants include:

Contractors and Subcontractors

Construction sites and industrial workplaces often involve multiple companies working side by side. If a contractor or subcontractor working on the same project acted carelessly and caused your injury, that company is not your employer and may not be shielded by workers’ comp exclusivity. A lawsuit against the negligent contractor may recover damages your employer’s policy never will.

Equipment and Machinery Manufacturers

Defective tools, machines, and safety equipment injure workers across every industry. If a piece of equipment malfunctioned due to a design or manufacturing defect, you may have a product liability claim against the manufacturer — or against the outside company hired to service and maintain it. This is true even if workers’ comp has already paid your medical bills. Our page on South Carolina personal injury claims describes how product liability claims are evaluated.

Property Owners

Not every workplace injury happens on your employer’s property. If you were hurt on a client’s premises, at a vendor’s facility, or on property your company does not own, the property owner may be liable for hazardous conditions. Wet floors left by an outside cleaning crew, unmarked drop-offs, or poorly maintained stairwells are common examples.

At-Fault Drivers

If your job requires you to drive — deliveries, sales calls, service calls, or operating a company vehicle — and another motorist caused the crash, you have the same right to pursue that driver as any other accident victim would. A third-party auto claim against the at-fault driver is separate from your workers’ comp claim and is not limited to two-thirds of your wages. Our South Carolina car accident lawyers handle these claims alongside workers’ comp cases.

Toxic Substance Manufacturers

Workers exposed to asbestos, industrial chemicals, or other hazardous substances may be able to file suit, depending on when the injury was discovered, the applicable deadlines, and the product history. These cases require careful investigation of product history and exposure records, and when successful, may result in recoveries that go beyond what workers' comp benefits provide.

What Does a Third-Party Claim Recover That Workers’ Comp Does Not?

Workers’ comp generally pays authorized medical care and wage benefits of about two-thirds of average weekly wages, subject to statutory limits. A successful third-party lawsuit can pursue:

• The remaining unreimbursed lost income workers’ comp does not replace
• Compensation for physical pain and emotional suffering
• Loss of enjoyment of life — the activities, hobbies, and family experiences your injury has taken away
• Future medical costs and future lost earning capacity if your injury is permanent
• Punitive damages, when legally available in cases involving willful, wanton, or reckless conduct

For a closer look at how the two types of claims compare, our FAQ on filing a third-party lawsuit alongside a workers’ comp claim walks through the key distinctions.

How Do the Two Claims Work Together?

Pursuing both a workers’ comp claim and a third-party lawsuit at the same time is procedurally complex but entirely permitted under South Carolina law. There are a few important rules to understand.

First, you cannot collect duplicate compensation for the same injury. South Carolina’s subrogation rules give your employer’s workers’ comp insurer a right to be reimbursed from your third-party recovery for benefits it already paid. Your attorney may be able to negotiate a reasonable repayment amount that protects the value of your settlement. Our FAQ on filing a third-party suit and receiving workers’ comp benefits explains how that process works in practice.

Second, the two actions have different deadlines. Workers’ comp has a 90-day reporting window and a two-year filing deadline. A third-party personal injury lawsuit generally must be filed within three years, though some claims have shorter or different deadlines. Missing a deadline can eliminate your right to recover.

Why Third-Party Claims Require a Different Kind of Investigation

Workers’ comp claims are primarily administrative. Third-party claims are litigation. To succeed, you must prove the defendant’s negligence caused your injury — you do not have to prove fault in workers’ comp. That means gathering evidence, identifying witnesses, retaining experts, and building a case before the trail goes cold. Our page on South Carolina workers’ compensation explains how our attorneys approach both sides of these cases simultaneously.

If your injury resulted in a long-term disability — a traumatic brain injury or spinal cord damage — the value of what a third-party claim can recover increases substantially. Workers’ comp may provide important medical and wage benefits, but it was not built to provide full tort damages such as pain and suffering or the full value of lost earning capacity.

What South Carolina Law Says About Negligence in Third-Party Cases

Proving negligence requires establishing four elements: the defendant owed you a duty of care, breached it, your injury resulted from that breach, and you suffered real damages. South Carolina also follows a modified comparative fault rule — your recovery is reduced by your share of fault, and you cannot recover at all if you are more than 50 percent responsible. Our article on negligence in South Carolina workers’ comp cases explains how that standard applies when a third party is involved.

The South Carolina Workers’ Compensation Commission oversees the workers’ comp side of these cases, while the third-party lawsuit proceeds in civil court. Navigating both systems simultaneously is one of the more complex scenarios a workplace injury attorney handles.

How Soon Should You Look Into a Third-Party Claim?

Early investigation matters. Physical evidence disappears. Witnesses move on. Surveillance footage gets overwritten. The moment you suspect your injury involved someone other than your employer, the question worth asking is whether a third-party lawsuit is also warranted.
