What is Burden of Proof?

The duty to prove disputed facts, which in civil cases means proving claims by a preponderance of the evidence (more likely than not).

Understanding Burden of Proof

The plaintiff bears the burden to prove all elements of their claims. "Preponderance of the evidence" means greater than 50% likelihood - much lower than the criminal standard of "beyond a reasonable doubt." The burden may shift for affirmative defenses.

Examples

  • 1Proving defendant's negligence caused injuries
  • 2Showing damages exceed $50,000
  • 3Establishing all elements of medical malpractice
