What Is the Burden of Proof in a Texas Personal Injury Case?
Written and legally reviewed by Greg Baumgartner | Founder & Lead Trial Lawyer, Baumgartner Law Firm | 40+ years of personal injury experience
In most Texas personal injury cases, the injured person must prove the claim. The usual standard is a preponderance of the evidence. In practical terms, the evidence must show that the facts supporting the claim are more likely true than not true. This is a lower standard than “beyond a reasonable doubt” in a criminal case, but it still requires credible proof.
A serious injury alone does not prove liability. The plaintiff generally must prove why the injury happened, who was legally responsible, how that conduct caused the injury, and the damages that followed. That is why our personal injury lawyers in Houston focus on preserving evidence early instead of waiting for an insurance company to decide what happened.
“After more than 40 years handling injury cases, I have learned that the severity of an injury and the strength of the proof are two different questions. A life-changing injury matters, but we still have to prove who was responsible and connect that conduct to the harm.” — Greg Baumgartner |
Who Has the Burden of Proof in a Texas Personal Injury Case?
The plaintiff — the person bringing the injury claim — usually has the initial burden of proof. The plaintiff must present enough evidence to establish each required part of the claim. In a negligence case, that normally means proving duty, breach of duty, causation, and damages.
The defendant can challenge that evidence and may raise defenses of its own. Some defenses carry their own proof requirements. But the basic point for an injured person is simple: don’t assume the insurance company or defendant will fill gaps in your proof.
A drunk-driving crash shows why the difference between civil and criminal proof matters. An injured person may have a valid civil claim even when the driver was never convicted of DWI. Learn how we investigate civil claims after a drunk-driving accident and develop evidence independently of the criminal prosecution.
What Does “Preponderance of the Evidence” Mean?
Preponderance of the evidence means the credible evidence weighs more in your favor. It is often described as “more likely than not.” It is not a head count of witnesses or a count of documents. One reliable video, record, or witness can matter more than several weak pieces of evidence.
The real question is whether the evidence, taken as a whole, persuades the judge or jury that the fact you must prove probably occurred.
What Must an Injured Person Prove?
Most Texas injury cases are negligence cases. Our guide to negligence in Texas explains the legal concept in more detail. At a basic level, the plaintiff usually must prove four things:
Element | What it means | Examples of proof |
Duty | The defendant owed a legal duty to act with reasonable care. | Traffic laws, safety rules, contracts, policies, or the parties’ relationship. |
Breach | The defendant failed to meet that duty. | Video, photographs, witness testimony, electronic data, records, admissions, or physical evidence. |
Causation | The breach actually and legally caused the injury. | Medical records, treating-doctor opinions, reconstruction evidence, symptom timing, and other facts connecting the event to the harm. |
Damages | The plaintiff suffered compensable losses because of the injury. | These include medical bills and records, wage proof, tax records, photographs, testimony, and evidence of future needs. |
Causation is often one of the most contested issues, especially when a prior condition existed or symptoms developed over time. See our guide to causation in personal injury claims and our discussion of medical evidence used to prove a Texas injury claim.
Serious Injuries Do Not Automatically Prove Liability
One of the most important distinctions in an injury case is the difference between liability and damages. Liability asks who is legally responsible. Damages ask what harm resulted and what compensation the law allows.
For example, a person may have a clearly documented surgery after a car accident, but the defense may still dispute who caused the crash or whether the collision caused the condition that required surgery. In a Houston truck accident case, the injury may be obvious while responsibility is spread among a driver, trucking company, maintenance contractor, or another party. Proof has to address both sides of the case.
What Evidence Can Help Meet the Burden of Proof?
The best evidence depends on how the injury happened. Useful proof may include:
- Scene photographs and video, including nearby surveillance or dash-camera footage.
- 911 recordings, body-camera footage, crash reports, and witness statements.
- Vehicle data, phone records, GPS information, and other electronic evidence when relevant.
- Company records, training materials, maintenance documents, and safety policies in commercial cases.
- Medical records, diagnostic imaging, physician opinions, and rehabilitation records.
- Employment records, tax documents, and other proof of lost income or earning capacity.
- Expert analysis when a medical, engineering, reconstruction, or economic issue requires specialized knowledge.
“I look first for evidence that does not depend only on someone’s memory. Video, electronic data, photographs, physical evidence, company records, and medical records created close in time to the event can make a disputed case much clearer.” — Greg Baumgartner |
In Texas courts, thorough preparation and professional presentation of this evidence are critical. Weak or missing evidence can lead to claim denials or verdicts in favor of the defense.
How Comparative Responsibility Can Affect the Case
Texas uses a proportionate-responsibility system. Under Texas Civil Practice and Remedies Code Section 33.001, a claimant may not recover damages if the claimant’s percentage of responsibility is greater than 50%. If the claimant is 50% or less responsible, the recovery is generally reduced by that percentage.
That rule gives defendants a reason to shift blame. Evidence about speed, lane position, traffic signals, reaction time, visibility, phone use, and the conduct of every involved party can become important. Our Texas comparative-fault guide explains the 51% rule in more detail.
Do Punitive Damages Require a Higher Burden of Proof?
Yes. Ordinary negligence claims generally use the preponderance standard, but Texas law imposes a higher standard for exemplary damages. Under Texas Civil Practice and Remedies Code Section 41.003, a claimant seeking exemplary damages must prove the required conduct by clear and convincing evidence.
That means ordinary carelessness is not enough. The statute addresses fraud, malice, and gross negligence. If those issues may be present, see our guide to punitive damages in Texas injury cases.
When Expert Testimony May Be Needed
Some facts can be shown with photographs, records, and eyewitness testimony. Other issues require expert help. A physician may explain medical causation or future treatment. An accident-reconstruction expert may analyze speeds, impact forces, or vehicle movement. An economist or vocational expert may address future income loss.
The Texas Rules of Evidence include Rule 702, which governs testimony by qualified expert witnesses. The need for an expert depends on the facts and the issues the defense chooses to contest.
The Same Proof Principles Matter in Wrongful Death Cases
A fatal loss does not remove the need to prove responsibility. In a Houston wrongful death case, the family may need evidence showing how the death occurred, who was responsible, causation, and the losses suffered by the eligible family members. Because key evidence may be controlled by a business, employer, trucking company, property owner, or other defendant, early investigation can be especially important.
Why Preserving Evidence Early Matters
Evidence can disappear long before a lawsuit reaches trial. Surveillance video may be overwritten. Vehicles may be repaired or sold. Electronic data can be lost. Employees change jobs, and witness memories fade. A strong case often starts with identifying what evidence exists and taking reasonable steps to preserve it.
“Waiting does not make a difficult proof problem easier. When a case is serious, I want to know early what evidence exists, who controls it, and what needs to be preserved before it changes or disappears.” — Greg Baumgartner |
Frequently Asked Questions About the Burden of Proof
Who has the burden of proof in a Texas personal injury case?
The injured plaintiff usually has the burden of proving the facts needed to establish the claim and the damages sought.
What does preponderance of the evidence mean?
It means the greater weight of credible evidence shows that a fact is more likely true than not true.
Is a police report enough to prove an injury case?
Not usually by itself. A report can be useful, but liability and causation may also depend on photographs, video, witnesses, physical evidence, medical proof, electronic data, and other records.
Can I prove a case without an eyewitness?
Yes. Many cases are proved with circumstantial and documentary evidence, such as video, vehicle damage, electronic data, medical records, physical evidence, and expert analysis.
Do I have to prove my medical damages?
Yes. A plaintiff seeking medical-expense or injury damages needs evidence supporting the injury, the connection to the incident, and the losses claimed.
Does being partly at fault automatically prevent recovery?
No. Under Texas proportionate-responsibility law, a claimant may still recover if the claimant is 50% or less responsible, although the recovery is reduced by the assigned percentage of responsibility.
Whether you were injured in a motor vehicle accident or another type of accident, starting your injury case promptly can help you gather the necessary evidence. This evidence is crucial to proving your case and securing a win.
