Texas Comparative Negligence Law and the 51% Rule

Under Texas comparative negligence law, you can still recover money for your injuries if you are partly to blame for the accident, but only if your share of the fault is 50 percent or less. If a jury puts you at 51 percent or higher, you recover nothing. If your fault stays at or below 50 percent, the court reduces your award by whatever percentage the jury assigns to you. These rules live in Chapter 33 of the Texas Civil Practice and Remedies Code, and they drive almost every decision in a Texas personal injury case.¹

The 50 Percent Line Decides Everything

The rule is binary at the threshold. A plaintiff found 51 percent responsible walks away with the same result as one found 99 percent responsible: zero.¹ The size of your medical bills, the permanence of the injury, the sympathy of the facts, none of it rescues the case once the fault number crosses the line.

The jury assigns a whole-number percentage of fault to every person involved, and the percentages must total 100.² That single number next to your name decides whether you collect anything and, if you do, how much. Because the stakes jump from “reduced award” to “no award” at a single percentage point, insurance adjusters and defense lawyers push every piece of available evidence toward pushing you past 50 percent during settlement talks.

How Your Damages Get Reduced

If your fault is 50 percent or less, the court takes your total damages and subtracts your percentage share.³ A $200,000 verdict with 30 percent fault assigned to you becomes a $140,000 recovery. The reduction applies across the board: medical bills, lost wages, pain and suffering, every category. The judge has no discretion to soften the math.

A second reduction kicks in if you already settled with any party before trial. The court subtracts the dollar amount of those settlements from what remains after the fault reduction.³ Imagine the same $200,000 verdict reduced to $140,000 for your 30 percent fault. If you had earlier taken $50,000 from one defendant to settle, the judgment against the remaining defendants drops to $90,000. Early settlements can still be the right call, but the offsets mean you need to run the numbers before signing anything.

Seat Belts Don’t Count Against You

Texas does not let defendants argue that your failure to wear a seat belt makes you more at fault or that your damages should be cut because of it. Your seat belt status at the time of the crash stays out of the proportionate-responsibility calculation.

When Comparative Negligence Doesn’t Apply

Chapter 33 governs most tort claims, including car wrecks, slip and falls, medical malpractice, product-liability claims involving defective or unreasonably dangerous products, and claims under the Texas Deceptive Trade Practices Act.⁴ A few situations fall outside the rules entirely:

Workers’ compensation claims operate under a separate system. If your employer carries workers’ comp and you were hurt on the job, the fault framework described here does not control your claim.⁴
Exemplary (punitive) damages are not reduced by your fault percentage, even when Chapter 33 governs the rest of the case.
Claims arising from methamphetamine manufacturing fall under a different chapter.

The workers’ comp carve-out trips people up most often, so confirm which system applies before you plan around the 50 percent rule.

Fault Among Multiple Parties and the Responsible Third-Party Trap

Most accidents involve more than two people, and Texas requires the jury to assign a share of fault to everyone who contributed to the harm. That includes you, the defendants, any party who settled earlier, and any designated responsible third party.² A court cannot submit a fault question for anyone unless there is enough evidence to support it.

The responsible third-party designation is the piece that quietly costs plaintiffs the most money. A defendant can file a motion to designate someone who contributed to the harm but was never sued, generally at least 60 days before trial.⁵ Courts can allow late filings for good cause. Once the designation is in, the jury can put a share of the fault on that person. The problem is that the designated third party is not a defendant, so nobody collects anything from them. Whatever percentage lands on them simply disappears from your recovery. Twenty-five percent on a designated third party means 25 percent you will never see.

The designation itself does not impose liability on the third party and cannot be used against them in a separate lawsuit.⁵ After discovery, you can move to strike the designation if there is no real evidence the person was responsible. Expect defendants to use the tool aggressively.

When One Defendant Can Be Made to Pay the Whole Judgment

The default rule is that each defendant pays only their share. A defendant assigned 20 percent of a $500,000 verdict owes $100,000, period. If another defendant goes bankrupt or disappears, you generally cannot shift that loss onto anyone else.⁶

The exception matters. When a single defendant’s fault exceeds 50 percent, that defendant becomes jointly and severally liable for the entire judgment. You can collect the full amount from them, and chasing contribution from the others becomes their problem rather than yours. A narrower trigger also exists for defendants who acted with specific intent to cause harm in concert with another person in connection with certain serious criminal offenses.⁶

What Actually Moves the Fault Percentage

Because that one number controls the outcome, the evidence used to set it carries real weight. A few sources tend to dominate:

Event data recorders. Most modern vehicles capture speed, braking, steering input, and airbag deployment in the seconds around a crash. The data comes straight from the vehicle, so it is hard to argue with.
Accident reconstruction experts. Engineers and forensic investigators use scene evidence, damage patterns, photos, video, and EDR data to rebuild the collision, often with simulations or 3D models for the jury.
Police reports. The investigating officer’s conclusions do not bind the jury, but insurers lean on them heavily in settlement talks.
Surveillance and dashcam video. When it exists, video tends to overrule conflicting witness memories.

In serious cases, both sides retain competing reconstruction experts. The plaintiff’s expert emphasizes the defendant’s speed; the defense expert points to the plaintiff’s missed blind-spot check. A few percentage points of movement can mean tens of thousands of dollars, or the loss of the entire case at the 51 percent line.

The Two-Year Filing Deadline

None of this matters if you file late. Texas gives you two years from the date of the injury to file a personal injury lawsuit. For wrongful death, the two-year clock starts on the date of death rather than the date of the accident.⁷ Two years passes faster than most people expect when treatment is ongoing and insurance negotiations stretch out. Filing the lawsuit preserves the claim even if you later settle. Missing the deadline forfeits the claim no matter how strong the facts are.
