What is property and casualty insurance?
P&C insurance is an umbrella term for a broad type of coverage that helps protect personal property – including home and vehicles – and cover against liability if someone is found legally responsible for an accident that causes bodily injury or property damage to others.
Apart from auto and home coverage, P&C policies include accident and health, commercial, farm, marine, aviation, credit, flood, surety, professional liability, private mortgage, and workers’ compensation insurance.
