If you are the primary breadwinner of the family and want to secure the financial future of your dependents, then you must have a life insurance policy. For the uninitiated, a life insurance is nothing but an agreement between you and the life insurance company, where you agree to pay an annual premium for a set period, and in return the insurer agrees to pay you a lump sum amount (‘life cover’) to your family, in case of your death within the policy period. Life insurance primarily serves as an income replacement after your death for the people who are economically dependent on you.
