Michigan General Liability Insurance

Michigan has specific requirements for general liability insurance that agents must understand.

Modified Comparative Negligence

Michigan uses modified comparative negligence with a 50% bar:

How It Works

  • Fault is allocated among all parties
  • Damages reduced by percentage of fault
  • 50% Bar: If 50% or more at fault, NO recovery
  • Different from states with 51% bar

Example

Driver A FaultDriver B FaultDriver A Recovery
40%60%60% of damages
49%51%51% of damages
50%50%NOTHING
60%40%NOTHING

Exam Tip: Michigan's 50% bar means you recover nothing if you are 50% OR MORE at fault. Some states use 51%.
