The insurance contract is a contract whereby the insurer will pay the insured (the person whom benefits would be paid to, or on the behalf of), if certain defined events occur. Subject to the "fortuity principle", the event must be uncertain. The uncertainty can be either as to when the event will happen (i.e. in a life insurance policy, the time of the insured's death is uncertain) or as to if it will happen at all (i.e. a fire insurance policy).
