A third party claim workers compensation case is a separate lawsuit an injured worker files against someone other than their employer whose carelessness helped cause the work injury. Workers’ comp pays your medical bills and part of your lost wages, no matter who was at fault. However, it does not pay for pain and suffering. A third party claim may cover what workers’ comp leaves out. Knowing this term early can help you protect money you may be owed.
What Third Party Claim Workers Compensation Means
In most states, workers’ comp is a trade-off. You get benefits without proving fault. In return, you generally cannot sue your employer. This is often called the “exclusive remedy” rule. However, that rule only protects your employer and, in many states, your co-workers. It does not protect outside parties. As a result, if someone else caused your injury, you may be able to sue them.
The “third party” is anyone outside the worker-employer relationship. For example, it could be a delivery driver who rear-ended your company truck. It could be the company that built a defective ladder. It could be a property owner who ignored a broken stair. A third party claim workers compensation case runs alongside your comp claim. It does not replace it.
How Third Party Claim Workers Compensation Works in a Real Claim
Here is a simple example. Maria drives a van for a bakery. A driver runs a red light and hits her. She breaks her arm and misses 10 weeks of work. Workers’ comp pays her medical bills and part of her weekly wages. However, it pays nothing for her pain or her full lost income. So Maria also files a claim against the at-fault driver’s auto insurance.
Now the money question comes in. The bakery’s comp insurer already paid Maria’s bills. In most states, the insurer gets a “lien” on her third party recovery. That means it can be paid back from her settlement. This repayment right is called “subrogation.” In many cases, the insurer must also share in the cost of her attorney fees. Some states also give the insurer a credit against future comp benefits.
Typically, the worker still comes out ahead. That is because a third party claim workers compensation case can include damages comp never pays. These may include pain and suffering and full lost wages. Any settlement figures you hear are illustrative only. Every case is different. Confirm the exact numbers with your state board and a licensed attorney.
How It Varies by State
Every state allows some form of third party claim workers compensation recovery. However, the rules on repayment, consent, and timing differ a lot. Some states require the insurer’s approval before you settle. Others limit repayment unless you were fully compensated. In some states, if you wait too long, the insurer can file the lawsuit itself.
The table below shows how five states handle the third party claim workers compensation process. These are summaries of each state’s statute. Laws change, so always check with your state workers’ comp board before relying on them.
| State | Statute | How the insurer gets repaid | Key timing or consent rule |
|---|---|---|---|
| New York | Workers’ Comp Law Section 29 | Lien on recovery, reduced by its share of legal costs; credit against future benefits | Carrier consent or court approval needed to settle, or future benefits may be lost |
| California | Labor Code Sections 3852-3861 | Employer or insurer lien on recovery for benefits paid | Employee must notify employer when filing; employer may join the suit |
| Florida | Statute Section 440.39 | Lien that may be reduced for comparative fault and limited recovery | Carrier may sue if the worker does not file within 1 year |
| Georgia | O.C.G.A. Section 34-9-11.1 | Lien only if the worker is fully and completely compensated | Employer may sue if the worker does not file within 1 year |
| Pennsylvania | Workers’ Comp Act Section 319 | Subrogation, reduced by a share of attorney fees and costs | Insurer’s lien attaches to the recovery; future credit may apply |
What to Do When You Hear This Term
First, take a breath. Hearing about a “third party claim” does not mean your comp claim is in trouble. It usually means someone thinks there may be more money available to you. Write down what happened and who was involved. Save photos, witness names, and any police or incident reports. Keep receiving medical care, and keep filing your comp paperwork on time.
Next, do not sign any settlement or release with an outside insurer before getting advice. In some states, settling without the comp insurer’s consent can cut off future benefits. A licensed attorney can explain how the lien and fees work in your state. For more terms like “subrogation” and “lien,” see our workers’ comp glossary. Then confirm the details with your state workers’ comp board.

Frequently Asked Questions
Can I get workers’ comp and file a third party claim at the same time?
Yes, in most cases you can do both. Your comp benefits typically continue while the third party claim workers compensation case moves forward. However, the comp insurer may be repaid from your third party recovery.
Do I have to pay back workers’ comp from my settlement?
In most states, the insurer has a lien on your third party recovery for benefits already paid. Many states reduce that lien by the insurer’s share of attorney fees. A few states, such as Georgia, limit repayment unless you were fully compensated.
Can I sue my employer instead of a third party?
In most cases, no. Workers’ comp is generally the exclusive remedy against your employer. A third party claim workers compensation case must be against someone outside that relationship, such as a driver or equipment maker.
