Elements of Comparative Fault

Quick Answer

What are the elements of Comparative Fault?

Comparative fault is a legal principle used in tort law that assigns fault to both the plaintiff and the defendant in an accident or injury case. This assessment determines each party’s percentage of fault and influences the damages awarded to the plaintiff.

Required Elements

1. Plaintiff's Negligence

The plaintiff must demonstrate that they acted negligently in a way that contributed to their injuries.

What to prove: It must be shown that the plaintiff's actions fell below the standard of care expected, helping to cause the accident or injury.

2. Defendant's Negligence

The plaintiff must establish the defendant's negligent behavior that led to the incident.

What to prove: Evidence must point to the defendant's failure to act as a reasonable person would under similar circumstances.

3. Apportionment of Fault

The total fault for the injury must be divided among all parties involved, including the plaintiff.

What to prove: An accurate determination of fault percentages for both the plaintiff and defendant must be shown to warrant damage calculation.

Burden of Proof

The burden of proof rests with the defendant to establish the plaintiff's comparative fault, usually by a preponderance of the evidence standard.

Available Defenses
  • Contributory Negligence
  • Assumption of Risk
  • Last Clear Chance
Common Fact Patterns
  • A car accident where both drivers were speeding, prompting an analysis of each driver's share of fault.
  • A slip and fall case where the plaintiff was found partially responsible for not paying attention to a 'wet floor' sign.
Exam Tip

Expect exam questions to involve fact patterns requiring the application of comparative fault principles and calculations of damages based on fault percentages.
