What type of life insurance beneficiary change allows the insurer to change the beneficiary without consent?

In a revocable beneficiary designation, the policyholder retains the right to change the beneficiary at any time without needing to obtain consent from the current beneficiary. This flexibility is a key characteristic of revocable designations, making it a popular choice for policyholders who may want to adjust their beneficiaries based on changing life circumstances, such as marriage, divorce, or the birth of a child.

In contrast, an irrevocable beneficiary designation locks in the beneficiary, which means that the policyholder cannot change the beneficiary without the irrevocable beneficiary's consent. This arrangement often provides a level of security for the beneficiary but limits the policyholder's control over the designation.

Given the definitions and implications of these types of beneficiary changes, revocable beneficiary designations are the only type that allows for changes without needing consent, making it the correct answer.
