Claims Process

Comparative Negligence

A legal doctrine that apportions fault between parties in a negligence claim. Damages are reduced by the claimant's percentage of fault. Different states apply pure, modified, or contributory negligence rules, each producing different outcomes on mixed-fault claims.

Comparative negligence is a legal doctrine that allocates fault between parties in a negligence claim and reduces damages by the claimant's percentage of fault. It shapes outcomes in third-party liability claims and in disputes where multiple parties contributed to a loss.

The Three Approaches

Pure comparative negligence reduces recovery by the plaintiff's percentage of fault, no matter how high. A plaintiff 90 percent at fault recovers 10 percent of their damages. Modified comparative negligence bars recovery when the plaintiff's fault exceeds a threshold, typically 50 percent or 51 percent. Contributory negligence, still used in a small number of states and the District of Columbia, bars recovery entirely if the plaintiff was even 1 percent at fault.

Why It Matters in Construction Losses

In construction and restoration, liability claims often involve mixed fault. A contractor causes damage but the property owner delayed notifying of a problem, contributing to the extent of the loss. A subcontractor makes an error but the general contractor missed the issue during inspection. In these cases, fault allocation — driven by the applicable comparative negligence rule — determines who pays what share.

Practical Implications

For first-party property claims against your own insurer, comparative negligence does not directly apply. What does apply are policy conditions like the duty to mitigate, which can reduce recovery when the insured failed to take reasonable steps. Understanding the difference between liability-side comparative negligence and first-party policy conditions keeps the analysis clean. For any significant dispute, state-specific legal advice matters because comparative negligence rules and their application vary widely.

Frequently asked questions

If you are partially at fault for your own loss, your recovery is reduced by your percentage of fault. Under a pure comparative negligence rule, you can still recover a portion even if you were 90 percent at fault. Under modified comparative negligence, you typically cannot recover if you were more than 50 percent or 51 percent at fault.

Comparative negligence reduces recovery by the plaintiff's percentage of fault. Contributory negligence, still used in a small number of states, bars any recovery if the plaintiff was even partially at fault. Contributory negligence is the harsher rule and is the minority position in the United States.

Comparative negligence applies in the context of liability claims (third-party claims for damage or injury caused by another party). First-party property claims — you suing your own carrier for coverage — are not subject to comparative negligence in the traditional sense, though policy conditions may create similar issues (like failure to mitigate).
