The Burden of Proof in Personal Injury Cases
In Texas civil law, the burden of proof in personal injury cases lies with the injured plaintiff. To prevail, the plaintiff must prove their claims by a “preponderance of the evidence.” The plaintiff must prove that it is more likely than not—over 50 percent —that the defendant’s actions caused their injuries. Unlike criminal cases that require proof “beyond a reasonable doubt,” personal injury claims operate on this lower evidentiary threshold. However, this standard still requires credible, organized, and persuasive evidence to convince a judge or jury.
Key Elements the Plaintiff Must Prove
Four essential elements must be established to meet the burden of proof in a personal injury case:
- Duty of Care: The victim must show that the defendant owed a legal duty of care. In many cases, this is straightforward. For example, drivers owe others a duty to operate vehicles safely. Property owners must maintain safe premises.
- Breach of Duty: The plaintiff must show that the defendant breached the duty through negligent or intentional actions. A breach can be proven in various ways, including expert testimony and eyewitness accounts.
- Causation: Causation links the breach of duty to the plaintiff's injuries. Texas law requires proof of two things: actual cause and proximate cause. Actual cause means that "but for" the defendant's action, the injury would not have happened. Proximate cause means that the harm was a likely result of the action. Medical records, accident reconstruction, and expert witness opinions are often vital in establishing this connection. Insurance defense attorneys understand the burden of proof and use the burden to their maximum advantage.
- Damages: Finally, the plaintiff must prove actual damages—economic or non-economic—resulting from the incident. The damages can include medical bills, lost wages, lower earning ability, pain, suffering, emotional distress, and other related costs. Receipts, tax documents, employment records, therapy notes, and doctor evaluations all support this claim. In cases involving permanent injuries, vocational and life care planners may be called to testify.
Types of Evidence That Strengthen a Personal Injury Claim
Meeting the burden of proof requires compelling documentation and testimony. Effective evidence includes:
- Medical records and diagnostic imaging
- Police and accident reports
- Eyewitness statements
- Photographs and video footage of the scene
- Employment and wage documentation
- Property damage appraisals
- Expert testimony (medical, engineering, vocational)
- Defendant's admissions or statements
- Cell phone or GPS data, when applicable
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 Negligence Affects the Burden of Proof
Texas follows a modified comparative fault rule under the Civil Practice and Remedies Code § 33.001. If the injured party is found to be more than 50 percent at fault for the accident, they cannot recover damages. If they are 50 percent or less at fault, their damages are reduced in proportion to their percentage of fault.
As a result, defendants often attempt to shift some or most of the blame to the injured party. The plaintiff must be prepared to counter these claims with strong, specific evidence to maintain eligibility for full or partial compensation.
Shifting the Burden in Product Liability and Res Ipsa Loquitur
In some cases, the burden of proof may partially shift. In product liability claims under the Texas Civil Practice and Remedies Code, Chapter 82, once a defect and resulting injury are established, the manufacturer may need to demonstrate that the product was misused or altered.
Similarly, under the doctrine of res ipsa loquitur (“the thing speaks for itself”), the court may infer negligence when an injury occurs under circumstances that ordinarily would not happen without negligence, such as surgical tools being left inside a patient. This legal doctrine allows plaintiffs to prevail even in the absence of direct evidence of negligence.
The Role of Expert Witnesses in Meeting the Burden of Proof
Expert witnesses are often indispensable in complex personal injury litigation. Medical experts explain the extent of injuries and future prognosis. Accident reconstruction experts analyze the mechanics of collisions. Economists estimate lost earning capacity. Their credibility and qualifications play a major role in how persuasively a plaintiff can meet their burden of proof.
Texas Rule of Evidence 702 governs the admissibility of expert testimony. Attorneys must ensure the expert’s methods are scientifically sound and relevant to the issues in dispute.
How Insurance Companies Use the Burden of Proof Against You
Insurance adjusters know that the injured party must prove their case. Sometimes, it can be hard to show who is at fault. Adjusters may delay claims, dispute causation, or question the severity of injuries. Adjusters often request unnecessary documentation and argue that the medical treatment was excessive or unnecessary.
An experienced trial lawyer expects these tactics. They built a strong case from the outset, supported by evidence. Meeting the burden of proof requires quick legal action
Securing and preserving evidence is a time-sensitive process. Witness memories fade, physical evidence may disappear, and deadlines under Texas’s two-year statute of limitations (Tex. Civ. Prac. & Rem. Code § 16.003) can cut off your right to file.
Acting timely is crucial to collecting and presenting the evidence necessary to prove your claims.
