Under an adjustable life insurance policy, which of the following may NOT be changed without further underwriting?

In the context of an adjustable life insurance policy, the one element that may not be changed without further underwriting is the person insured. This is due to the fact that the individual covered by the policy is typically the central aspect of the risk being underwritten. Any change to the insured person would require a thorough re-evaluation of the health risk, which is why it necessitates further underwriting.

Adjustable life insurance allows policyholders to make modifications to various elements of the policy. For instance, the premium amount, death benefit amount, and the policy's duration can often be adjusted depending on the holder’s needs and circumstances. However, changing the individual who is insured fundamentally alters the risk profile of the policy, thus necessitating additional underwriting processes to assess the new insured’s health status and associated risks accurately.
