Which type of beneficiary designation ensures that a deceased beneficiary's share passes to their living descendants?

The designation that ensures a deceased beneficiary's share passes to their living descendants is known as "Per Stirpes." This method of distribution allows for the deceased beneficiary's portion to be divided among their children or other descendants, effectively maintaining the family lineage in the allocation of benefits.

For example, if a parent is a beneficiary and they pass away before the individual who holds the policy, their share would not simply disappear or be redistributed among the remaining beneficiaries. Instead, it would go to their children (the living descendants), ensuring that the deceased beneficiary's portion benefits their direct heirs.

In contrast, the other options focus on different aspects of beneficiary designations. "Per Capita" would distribute a deceased beneficiary's share equally among the surviving beneficiaries at the same generation level, without considering the descendants of any deceased beneficiaries. "Revocable" and "Irrevocable" refer to the ability to change or not change the beneficiary designation after it's set, but they do not inherently address how shares would be distributed in the event of a beneficiary's death. Thus, "Per Stirpes" is the appropriate choice for ensuring that a deceased beneficiary's share flows down to their living descendants.
