For a life insurance policy to be valid, when must the policyowner have an insurable interest in the insured?

解析

In life insurance, insurable interest must exist at the inception of the contract (when the policy is applied for), not at the time of loss. This differs from property insurance, where insurable interest must exist at the time of the loss. Requiring it continuously is incorrect: for example, a business may keep key-person coverage even after buying the policy, and a divorced spouse's policy can remain valid. Making it depend on the beneficiary's relationship confuses insurable interest (a relationship between owner and insured) with the separate question of who receives the proceeds.
