The essential limits of insurance protection are then the requirement of the written form, contingency of the insured event, exclusion of deliberate action, good faith of both parties, obligation to pay premium, and statue of limitation. The paper then deals with general limits of insurance against loss and damage and limits of agreed sum insurance.
