Dear student,
According to the principle of insurable interest, the insured must have some interest vested in the object which is being insured by him, in the absence of which the insurance policy is considered as a gamble and the contract will be void.
It must be present in different types of insurance in the following manner:
Life insurance: At the time of taking the policy and not necessarily at the time of receiving the claim.
Fire insurance: Both at the time of taking the policy and receiving the claim
Marine insurance: Only at the time of receiving the claim or at the time of loss.
