Which term describes naming a contingent beneficiary as 'all of my children'?

A successive beneficiary is one who is designated to receive benefits only after the primary beneficiary has passed away or is unable to claim. This classification does not pertain to naming a group of individuals but rather to the order of beneficiary claims.

A tertiary designation refers to the third level of beneficiaries in a hierarchy, coming into play only if both primary and secondary beneficiaries are unable to claim benefits. This term does not relate to naming a group and does not describe the collective naming of 'all of my children'.

A trust arrangement involves setting up a legal entity to hold and manage assets for beneficiaries according to specified terms. While this can include contingent beneficiaries, it does not specifically define the act of naming a group, such as 'all of my children', as beneficiaries.
