What Is Preponderance of Evidence 

Preponderance of Evidence is a standard of proof used in most civil trials, including family law cases. This standard is met when a party convinces the court that there is a greater than 50% chance that their claim is true. It is a lesser standard of proof compared to criminal law standards, emphasizing the likelihood over the certainty of a claim being true.


Unlike "Beyond a Reasonable Doubt," the highest standard used primarily in criminal trials, Preponderance of Evidence does not require the proof to be so conclusive. "Beyond a Reasonable Doubt" demands a high level of certainty, as it deals with the potential deprivation of personal liberties in criminal cases. In contrast, Preponderance of Evidence is used in civil cases where the stakes, typically involving property or personal rights rather than freedom, are considered lower.

How is Preponderance of Evidence Applied in Personal Injury Cases?

The application of this standard can be somewhat subjective, as it involves weighing the evidence to see which side is more convincing. For example, in a car accident case, if the plaintiff alleges that the defendant ran a stop sign leading to the accident, the plaintiff must prove, through evidence such as witness testimony and documents, that it is more likely than not that the defendant breached their duty to drive safely.


It's important to note that in certain situations, a higher standard of proof, known as "Clear and Convincing Evidence," might be applied. This standard is used in cases involving fraud, claims for punitive damages, potential loss of parental rights, restraining orders, requests to withdraw life support, and in matters concerning wills or conservatorships. Under this standard, the evidence must be substantially more convincing than in the Preponderance of the Evidence standard.

Key Aspects of Preponderance of Evidence in Personal Injury



  • Nature of the Standard: It requires the evidence to tilt in favor of the plaintiff’s argument, showing that there is a greater than 50% chance that the claim is true.
  • Application in Case Types: This standard is applied in various personal injury cases, including car accidents, slip and fall incidents, medical malpractice, and more.
  • Evidential Requirements: The plaintiff must present evidence that makes their version of events more probable than not. This could include witness testimonies, medical reports, expert opinions, and other relevant documentation.
  • Role in Decision Making: Judges or juries weigh the evidence presented by both parties. The side with the more convincing and substantial evidence, meeting the preponderance threshold, usually prevails.
  • Comparative Fault Considerations: In some instances, the defendant may argue comparative fault, suggesting that the plaintiff shares some responsibility for the incident. The standard of Preponderance of Evidence applies to these claims as well.
  • Importance of Legal Representation: Given the nuances of presenting and arguing evidence effectively, legal representation becomes crucial.
