Final answer:
If a policy owner wants to change an irrevocable beneficiary on a Life Insurance policy, they can only do so with the consent of the current beneficiary, as the irrevocable designation grants the beneficiary a vested interest in the policy.
Step-by-step explanation:
If T is the policy owner for a Life Insurance policy with an Irrevocable beneficiary designation and wishes to change the beneficiary, T has limited options. The correct option is that T can change the beneficiary only with the consent of the current beneficiary. This is because an irrevocable beneficiary designation means that the beneficiary has a vested interest in the policy and T cannot unilaterally change this designation. If the current irrevocable beneficiary agrees to relinquish their rights or consents to the change, then T may proceed to change the beneficiary. Without such consent, T's hands are tied.
