Workers’ compensation is often the first, and sometimes the only, resource an injured employee thinks of after a workplace accident. But in certain situations, Montana law allows an injured worker to pursue additional compensation beyond what workers’ comp provides, through a separate claim against a party other than the employer.
How Workers' Compensation Normally Works
Workers’ compensation generally provides medical benefits and partial wage replacement regardless of who was at fault for the accident, but in exchange, it typically prevents an employee from suing their employer directly for additional damages like pain and suffering. This tradeoff is often called the exclusive remedy rule, and it applies to claims against your own employer specifically.
When a Third-Party Claim May Apply
If someone other than your employer or a coworker contributed to your injury, you may be able to pursue a separate personal injury claim against that third party, in addition to your workers’ comp benefits. Common third-party scenarios include a defective piece of equipment made by an outside manufacturer, a subcontractor’s negligence on a job site, or a car accident that happens while you’re driving for work.
Why Third-Party Claims Matter
Workers’ compensation benefits are often limited compared to what a full personal injury claim could recover, since workers’ comp generally doesn’t include pain and suffering. A third-party claim can fill that gap, potentially recovering compensation that workers’ comp alone doesn’t provide, particularly for injuries that cause lasting pain, scarring, or reduced quality of life.
Comparative Fault in Third-Party Claims
Montana’s modified comparative fault rule applies to third-party workplace injury claims. You can recover damages as long as you were less than 51% at fault, with your award reduced by your percentage of responsibility.
Examples of Third-Party Workplace Claims
- A defective tool or machine that malfunctioned due to a manufacturing defect
- A delivery driver injured in a car accident caused by another driver
- An employee of one company injured by the negligence of a different company’s employee on a shared job site
Can You Pursue Both Workers' Comp and a Third-Party Claim?
In many cases, yes. Workers’ comp and a third-party claim address different sources of responsibility, though there can be coordination requirements between the two, including potential reimbursement of workers’ comp benefits from a third-party settlement. This reimbursement, sometimes called a subrogation lien, is something an attorney can help negotiate down so it doesn’t consume an unfair share of your recovery.
Multi-Employer Job Sites
Construction and industrial sites often involve workers from several different companies working alongside one another. When an employee of one company is injured due to the negligence of another company’s crew or supervisor, that separate company is generally treated as a third party, even though everyone was working toward the same project, opening the door to a claim beyond workers’ comp.
The Statute of Limitations
A third-party personal injury claim generally follows Montana’s standard 3-year statute of limitations, separate from any workers’ comp filing deadlines, so it’s important to track both timelines carefully and not assume one filing satisfies the other.
Talk to an Attorney About Your Options
If your workplace injury involved a third party’s negligence, an attorney can help you understand whether a claim beyond workers’ compensation is available and how the two processes interact, so you don’t leave compensation on the table by only pursuing one path.
How a Subrogation Lien Is Handled
When a third-party claim succeeds, the workers’ comp insurer that already paid your medical bills and wage benefits often has a legal right to be reimbursed from that settlement, known as a subrogation lien. Negotiating the size of that lien is a routine part of resolving a third-party claim, and an experienced attorney can often reduce it so more of the settlement stays with you rather than going back to the workers’ comp carrier.
Reporting Requirements You Shouldn't Skip
Even when a third-party claim looks likely, it’s still important to report the injury to your employer and file for workers’ comp benefits promptly, since missing that separate deadline can jeopardize your medical coverage and wage benefits while the third-party case is still being developed. The two processes run on their own timelines and require their own notice, even though they’re connected to the same underlying injury.
What If You're Not Sure Whether a Third Party Was Involved
Many injured workers don’t immediately realize a third party played a role in their accident, especially when the workplace itself seems like the obvious setting for the injury. An attorney reviewing the details of how an accident happened, including any equipment involved, other companies present at the job site, or vehicles used in the course of employment, can often spot a third-party angle that wasn’t obvious at first glance.
Deadlines Matter Even When You're Not Sure Yet
Because it can take time to determine whether a third party contributed to a workplace injury, it’s worth having a case reviewed well before Montana’s 3-year filing deadline approaches, rather than waiting until you’re certain a third-party claim exists. Evidence about equipment condition, job site staffing, and vehicle maintenance records can all become harder to obtain the longer a claim sits unexamined.
