Do Homeowner’s Insurance or Umbrella Policies cover this sort of thing?
Homeowner’s and umbrella policies RARELY specify the coverage of self-defense acts with a firearm. For many policyholders, the answer is "no." Most standard home and auto policies contain a liability clause that specifically excludes coverage for injuries or damage caused by an intentional act such as firing a gun, even in self-defense. Even if the law recognizes your right to defend yourself, insurance companies see it differently, according to the International Risk Management Institute (IRMI). Policies often contain an intentional injury exclusion, which defines self-defense as an intentional act and therefore excluded from compensation.
If someone is accidentally injured on your property, your home insurance liability coverage will cover medical bills and the resulting legal fees. But if you fire a gun at an intruder and you end up in court, the deliberateness of the act (even if it was in self-defense) means that your home insurance policy may not cover the resulting costs.
