Yes, you can. In the general insurance contracts, cancellation of the policy leads to either a proportionate refund of the premiums or a refund of premiums on a short period basis.
However, under a life assurance contract, some companies provide a 30‐day period (cooling off period), whereby if the policyholder decides to withdraw within the period, he/she can cancel the policy and obtain a refund less administrative expenses incurred by the insurance company. The refund on any policy is guided by the cancellation clause.
