Property insurance protects against the financial loss a person or business suffers when damage occurs to one's property, such as the structure and contents of a home or building. Casualty insurance, or liability insurance, protects against legal liability when a person or business becomes obligated to pay for another person’s physical injuries or property damage. A licensed property and casualty insurance professional will assess a client's needs and identify a full range of insurance products to protect the client from a property or casualty claim. A property and casualty agent may work with personal or commercial lines of insurance.
