What is Casualty Insurance?
Casualty insurance is traditionally one of the most difficult and nebulous types of insurance to define. One of the main reasons is that is has evolved to deal with elements of risk that are not strictly cash loss related. While similar to some functions of marine insurance that deal with un-provable loss, casualty insurance has evolved to cover elements of risk that are similar to liability insurance.
The similarity to marine insurance is more that just coincidental as casualty insurance has its origins in marine insurance. In general terms, one of the best ways of understanding of casualty insurance is using the liability insurance connection; that is not intended to cover third-party liability per se. One of the more directly understandable forms of causality insurance is workers compensation insurance.
in 1946, the National Association of Insurance Commissioners defined, casualty insurance as a blanket term for legal liability except marine, disability and medical care, and some damage to physical property. This would seem to conflict with the association of workers compensation insurance as a form of casualty coverage, which is due to the shifting definition of insurance as the nature of risk expands.
In 1946, it would have been nearly impossible to purchase insurance coverage for a nuclear accident, as the technology did not exist just yet. However, in recent years, now there are specialized policies that are purchased by families that live near nuclear power plants. The state of Illinois, for example, defines Glass insurance as a form of casualty insurance along with a number of other risk types, such as livestock and miscellaneous coverage, just as every state has their own terms for casualty insurance.
