Kentucky Pure Comparative Negligence

Understanding Comparative Negligence

Comparative negligence determines how damages are allocated when multiple parties share fault in an accident. Kentucky uses the most plaintiff-friendly version: pure comparative negligence.

Kentucky's Pure Comparative Negligence Rule

Legal Foundation

Kentucky's pure comparative negligence system was established by:

  • Kentucky Revised Statutes Section 411.182
  • Hilen v. Hays (1984) - Kentucky Supreme Court decision
  • Replaced the harsh contributory negligence doctrine

How Pure Comparative Negligence Works

Under pure comparative negligence:

  • Fault is apportioned by percentage to each party
  • Damages are reduced by the claimant's percentage of fault
  • Recovery is permitted even if plaintiff is more at fault than defendant
  • No threshold bars recovery

Comparison of Negligence Systems

SystemRecovery Permitted If...
Contributory0% at fault (any fault bars recovery)
Modified (50% Bar)49% or less at fault
Modified (51% Bar)50% or less at fault
Pure ComparativeAny percentage, even 99% at fault

Kentucky uses pure comparative negligence, the most favorable to plaintiffs.

Calculating Damages Under Pure Comparative Negligence

Basic Formula

Recovery=Total Damages×(100%Plaintiff’s Fault %)\text{Recovery} = \text{Total Damages} \times (100\% - \text{Plaintiff's Fault \%})

Example Calculations

Scenario 1: Plaintiff 20% at fault

FactorAmount
Total Damages$100,000
Plaintiff's Fault20%
Recovery$80,000

Scenario 2: Plaintiff 60% at fault

FactorAmount
Total Damages$100,000
Plaintiff's Fault60%
Recovery$40,000

Scenario 3: Plaintiff 90% at fault

FactorAmount
Total Damages$100,000
Plaintiff's Fault90%
Recovery$10,000

Key Point

In Kentucky, even a driver who is 99% at fault can still recover 1% of their damages from the other party.

Historical Context

Before 1984: Contributory Negligence

Before Hilen v. Hays:

  • Kentucky followed contributory negligence
  • Any fault by plaintiff completely barred recovery
  • Harsh results for plaintiffs with minor fault
  • Courts often manipulated facts to achieve fair results

Hilen v. Hays (1984)

The Kentucky Supreme Court:

  • Adopted pure comparative negligence
  • Recognized unfairness of contributory negligence
  • Aligned with modern tort law principles
  • Made Kentucky one of 12 pure comparative states

Implications for Auto Insurance

Claims Handling

Under pure comparative negligence:

SituationEffect on Claim
Both parties at faultBoth may have valid claims
Plaintiff mostly at faultStill can recover some damages
Multiple defendantsApportionment among all parties
Unclear faultInvestigation crucial

Insurance Premiums

Pure comparative negligence can impact:

  • Higher claim frequency (more people can recover)
  • More complex claims handling
  • Potential for overlapping claims
  • Need for adequate liability coverage

Example: Two-Car Collision in Kentucky

Accident Scenario:

  • Driver A runs red light
  • Driver B was speeding
  • Collision causes injuries to both

Fault Determination:

  • Driver A: 70% at fault (ran red light)
  • Driver B: 30% at fault (speeding)

Damages:

  • Driver A's damages: $50,000
  • Driver B's damages: $80,000

Recovery:

  • Driver A can recover: $50,000 × 30% = $15,000
  • Driver B can recover: $80,000 × 70% = $56,000

Practical Considerations

For Producers

When advising Kentucky clients:

  • Explain that fault doesn't bar recovery
  • Recommend adequate liability limits
  • UM/UIM important even for "at-fault" drivers
  • Document all accidents thoroughly

For Insureds

Important to understand:

  • You may receive a claim even as the "injured" party
  • Your damages may be reduced by your fault
  • Keep detailed records of accidents
  • Don't admit fault at accident scene

Exam Tip: Kentucky is one of only 12 states with pure comparative negligence. Remember that ANY percentage of fault allows recovery, unlike modified comparative states where recovery may be barred at 50% or 51% fault.
