(a) A policy may be assignable or not assignable, as provided by its terms. Subject to its terms relating to assignability, any life or disability policy, whether heretofore or hereafter issued, under the terms of which the beneficiary may be changed upon the sole request of the owner, may be assigned either by pledge or transfer of title by an assignment executed by the owner alone and delivered to the insurer, whether or not the pledgee or assignee is the insurer. Any such assignment shall entitle the insurer to deal with the assignee as the owner or pledgee of the policy in accordance with the terms of the assignment until the insurer has received at its home office written notice of termination of the assignment or pledge or written notice by, or on behalf of, some other person claiming some interest in the policy in conflict with the assignment. No such written assignment is required in the case of a policy loan made by the insurer under the terms of the policy.
(b) A policy of life insurance, taken out by the insured himself or by a person having an insurable interest in the life of the insured, in good faith may, unless the policy provides otherwise, be assigned to anyone as any other chose in action without regard to whether the assignee has an insurable interest in the life insured or not.
