In civil law, what is the standard of proof required to determine liability?

• A. Beyond a reasonable doubt
• B. Clear and convincing evidence
• C. Preponderance of the evidence
• D. Probable cause

Answer: (C)

In civil cases, liability is determined when the plaintiff proves it is more likely than not that the defendant is responsible. This is called a preponderance of the evidence—the scales tilt just slightly in the plaintiff’s favor, meaning the probability of liability is greater than 50%. It’s a lower standard than criminal cases, which require proof beyond a reasonable doubt. Probable cause is about the basis for filing charges or making an arrest, not the trial’s burden of proof. Clear and convincing evidence is used only in specific civil contexts, not for ordinary liability determinations. So, the best answer is that liability is shown by a preponderance of the evidence.
