What Is a Third Party in an Injury Case?
A third party is someone outside the main relationship in a claim. Who counts depends on the context:
- Work injuries: anyone other than you and your employer
- Insurance: a claim against another person’s policy rather than your own
- Lawsuits: a person or company a defendant brings into the case
Third-Party Claims After a Work Injury
This is the most common use of the term. Texas workers’ compensation pays medical bills and part of lost wages, but it does not pay for pain and suffering. When an employer has workers’ comp, you generally cannot sue the employer for negligence.
You may still sue an outside party whose negligence contributed. Examples include:
- A driver who hits you while you are making deliveries
- A subcontractor that leaves a hazard on a construction site
- A manufacturer of defective machinery or tools
- A property owner who failed to fix a dangerous condition
Proving and Valuing a Third-Party Claim
A third-party claim is a standard negligence case. You must show the party owed you a duty, breached it, and caused your injury. Texas modified comparative fault applies, so your recovery is reduced by your share of fault and barred above 50%.
Unlike workers’ comp, a third-party claim can include full lost wages, future medical care, and non-economic damages such as pain and mental anguish.
Responsible Third Parties and Other Parties Brought Into a Case
Defendants often point to someone else. Under CPRC §33.004, a defendant can designate a responsible third party, and the jury may assign that person a percentage of fault. A defendant can also bring a new party into the suit directly, sometimes called impleader.
These moves can shift liability and change who pays. Identifying every responsible party early, within the two-year filing deadline, protects your claim.

Frequently Asked Questions
What is a third-party claim, by definition?
It is a claim brought against a party outside the core relationship in a case. For injured workers, that means someone other than the employer. In insurance, it means a claim against another person's policy rather than your own. In a lawsuit, it can also mean a defendant bringing a new party into the case.
Can I file a third-party claim for a work injury in Texas?
Often, yes. If a negligent driver, subcontractor, property owner, or equipment manufacturer contributed to your on-the-job injury, you may have a claim against them even while receiving workers' compensation. Your workers' comp carrier may have a right to be repaid from that recovery.
What is a responsible third party in Texas?
Under Section 33.004 of the Civil Practice and Remedies Code, a defendant can ask the court to designate a person who is not a party to the suit as partly responsible for the harm. The jury can then assign that person a share of fault, which may reduce what the defendant owes.
How long do I have to file a third-party injury claim?
Most Texas personal injury lawsuits, including third-party claims, must be filed within two years of the injury under CPRC §16.003. Claims involving a government entity can require written notice within six months or less. Starting early also helps preserve evidence.
