You pay nothing until we win.

Published on June 26, 2026 by Ken Christensen

Burden of Proof

When you file a personal injury claim in Utah, you must present enough evidence to show that another party’s negligence more likely than not caused your injuries and damages. In civil cases like personal injury lawsuits, a lower burden of proof applies, and understanding what that means can help you feel more confident about your legal options. The evidence required to win a personal injury case is significantly less demanding than that required to prove a criminal case.

Good Guys Injury Law helps injured victims in Utah meet the burden of proof and build the strongest possible personal injury case. Our legal team knows what evidence is needed, how to gather it, and how to present it persuasively to a judge or jury. We handle every case on a contingency fee basis, so you pay nothing unless we win.

What Does “Burden of Proof” Mean in a Personal Injury Case?

In any court proceeding, one party must present evidence strong enough to convince a judge or jury that their version of events is correct.

In personal injury law, that responsibility falls on the injured person. Understanding how this works helps you know what your case needs to succeed.

Why the Burden of Proof Matters

The burden of proof determines how much evidence you need to win your case. If you cannot present sufficient evidence to meet the required legal standard, the defendant wins regardless of what actually happened. This is why gathering strong evidence from the very beginning of your personal injury case is so important.

Who Has the Burden of Proof?

In a personal injury lawsuit, the burden of proof lies with the plaintiff, who is the injured person. You must prove that the other party was negligent and that their negligence caused your injuries and damages.

What Must You Prove to Win a Personal Injury Case in Utah?

To win a personal injury case in Utah, you must prove four specific elements by a preponderance of the evidence. Each element builds on the last, and failing to prove any one of them can defeat your claim entirely.

The Defendant Owed a Duty of Care

You must show that the defendant had a legal responsibility to act reasonably toward you. For example, drivers owe a duty of care to other people on the road, and property owners owe a duty to keep their premises safe for visitors.

The Defendant Breached That Duty

You must show that the defendant failed to meet their duty of care by acting in a way that a reasonable person would not. A driver who ran a red light or a property owner who ignored a known hazard has likely breached their duty of care.

The Breach Caused Your Injuries

You must prove a direct link between the defendant’s breach and the injuries you suffered. It is not enough to show that the defendant was negligent. You must show that their specific negligence caused your specific harm.

You Suffered Damages

You must show that you suffered real, measurable losses as a result of your injuries, including medical bills, lost wages, pain and suffering, and other losses. Without provable damages, you cannot recover compensation even if the defendant was clearly at fault.

What Is the Standard of Proof in a Utah Personal Injury Lawsuit?

The standard of proof in a personal injury case is lower than in a criminal case but still requires enough evidence to persuade a judge or jury that your version of events is more likely true than not. Meeting this standard is the foundation of every successful personal injury claim.

Understanding “Preponderance of the Evidence”

Preponderance of the evidence means that your evidence must show it is more likely than not that the defendant’s negligence caused your injuries. Think of it as a scale that just barely tips in your favor. You do not need absolute certainty or clear and convincing evidence. You simply need enough evidence to show your account of events is more probable than the defendant’s.

How Civil Cases Differ From Criminal Cases

In criminal cases, the prosecution must prove guilt beyond a reasonable doubt, the highest legal standard.

Personal injury cases use a lower standard because the consequences are financial rather than criminal. The defendant will not be proven guilty or face jail time. Instead, they may be required to pay compensation to the injured person.

Examples of Meeting the Burden of Proof

Meeting the preponderance standard looks different depending on the type of personal injury case. Here are common examples of how plaintiffs satisfy this evidentiary standard:

  1. A car accident victim presents a police report, medical records, and a witness statement showing the other driver ran a red light and caused the crash
  2. A slip and fall victim provides surveillance footage showing a wet floor with no warning signs and medical records documenting injuries from the fall
  3. A dog bite victim presents photographs of injuries, a neighbor’s testimony about the dog’s prior aggression, and an emergency room report from the date of the attack

What Evidence Can Help Prove a Personal Injury Claim?

Building a strong personal injury case requires presenting the right evidence to meet the burden of proof. The stronger and more complete your evidence, the harder it is for the defendant to challenge your claim.

Key types of evidence include:

  • Medical Records and Bills: Documentation of your injuries, the treatment you received, and the costs you incurred connects your harm directly to the accident and establishes the value of your damages.
  • Accident Reports: Police reports and incident reports create an official record of what happened, who was involved, and any initial fault determinations made at the scene.
  • Witness Testimony: Statements from people who saw the accident or are familiar with the conditions that caused it can corroborate your account and make your claim more persuasive to a jury.
  • Photographs and Video Evidence: Photos of the accident scene, visible injuries, property damage, and hazardous conditions provide powerful visual proof that supports your version of events.
  • Expert Witness Opinions: Medical professionals, accident reconstruction experts, and other specialists can provide testimony that explains complex issues to a jury and strengthens the causation and damages elements of your claim.

How Defendants Try to Challenge the Burden of Proof

Defendants and their insurance companies rarely accept liability without a fight. They look for weaknesses in the evidence presented and raise arguments designed to create doubt about your claim.

Disputing Liability

The defendant may argue that they did not owe you a duty of care or that they acted as a reasonable person would under the circumstances, meaning no breach occurred. Disputing liability is the most direct way to defeat a personal injury claim before it reaches the damages stage.

Challenging Causation

Even if the defendant admits a dangerous condition existed, they may argue that it did not cause your specific injuries. They might suggest that a pre-existing condition, a separate incident, or your own actions were the real cause of your harm rather than their negligence.

Questioning the Severity of Injuries

Defendants frequently argue that your injuries are not as serious as you claim or that you have not suffered the damages you are seeking. They may point to gaps in medical treatment, inconsistencies in medical records, or social media activity to suggest your injuries are exaggerated.

Arguing That Another Party Was Responsible

In some cases, the defendant argues that a third party, not themselves, was responsible for the accident. This shifts attention away from their own conduct and may reduce or eliminate the percentage of fault assigned to them.

How Does Utah’s Comparative Fault Law Affect the Burden of Proof?

Under Utah Code § 78B-5-818, Utah uses a modified comparative fault system. You can recover compensation in a personal injury case as long as your share of fault is less than 50%.

However, your total compensation is reduced by your percentage of fault. If you are 30% at fault, your compensation drops by 30%. At 50% or more, you recover nothing.

Proving the Defendant’s Percentage of Fault

When comparative fault is at issue, you must present evidence showing that the defendant bears the greater share of responsibility for the accident. The stronger your evidence of the defendant’s negligence, the harder it is for them to shift significant fault onto you.

Responding to Comparative Fault Allegations

When a defendant claims you were partly responsible, your attorney must present all the evidence needed to counter that argument. Witness statements, video footage, and expert testimony are often critical in pushing back against attempts to assign you an unfair share of fault.

How Shared Fault Can Impact Compensation

Because every percentage of fault assigned to you reduces your recovery, defendants have a strong financial reason to argue that you contributed to the accident. Working with an experienced personal injury lawyer who understands how to counter these arguments is one of the most important steps you can take to protect the full value of your claim.

Common Challenges in Proving a Personal Injury Case

Even strong personal injury cases face obstacles. Knowing the most common challenges helps you and your attorney prepare for them in advance.

  • Lack of Evidence: Without photos, witness statements, or other documentation from the accident scene, proving what happened becomes much harder. Acting quickly to preserve evidence after an accident is critical.
  • Delayed Medical Treatment: Waiting days or weeks to see a doctor gives the defense a strong argument that your injuries were not serious or were not caused by the accident. Seek medical attention immediately after any accident.
  • Pre-Existing Injuries: If you had prior injuries to the same part of your body, the defendant will argue your current condition is not their fault. Medical records that document a clear change after the accident are essential to overcoming this defense.
  • Conflicting Witness Statements: When witnesses give different accounts of what happened, it creates doubt that the defense will exploit. Your attorney must work to establish which version of events is most consistent with all the evidence presented.
