Insurance involves an insurer agreeing to compensate an insured for specified losses in exchange for premium payments. Key parties are the insurer and insured, with their relationship outlined in an insurance policy. Insurance covers losses to property from events like fire or accidents, as well as life-related contingencies like death. There are different types of insurance like life, fire, marine, and general insurance. The Insurance Regulatory and Development Authority (IRDA) regulates and promotes the insurance sector in India, issuing licenses to companies and setting rules on capitalization, investments, and consumer protection.
