Comparative negligence is a legal rule that allocates fault among the parties to an accident and reduces damages according to each party’s share of responsibility. In plain language, it means an injured person can still recover in many cases even if they were partly at fault, but the recovery is reduced by that percentage of fault.
Why it matters in insurance claims
Comparative negligence matters most in liability claims. When an adjuster or court evaluates an accident, the question is not always whether one side was entirely right and the other entirely wrong. Often the real issue is how responsibility should be divided.
That allocation can affect:
- bodily injury settlements
- property damage claims
- subrogation recovery
- litigation strategy
- reserve setting on liability files
For insurers, the doctrine shapes how damages are valued and how much of a claimed loss the insured or claimant may actually recover.
Pure versus modified systems
Jurisdictions do not all apply the doctrine the same way. Some follow pure comparative negligence, where a claimant can recover even if mostly at fault, with the award reduced by that percentage. Others use modified comparative negligence, where recovery is barred once the claimant reaches a specified fault threshold.
Because the exact rule depends on local law, comparative negligence should always be read with jurisdiction in mind.
Practical example
Suppose a driver suffers $100,000 in damages but is found 25 percent responsible for the crash. Under comparative negligence, the recoverable amount may be reduced to $75,000. If the jurisdiction uses a modified system and the claimant crosses the applicable threshold, recovery may be reduced further or barred entirely.
