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

A tertiary designation refers to a third level of beneficiaries, typically coming into play if primary and secondary beneficiaries are unable to receive benefits. This term does not apply to naming a group such as 'all of my children', as it specifically addresses the order of beneficiaries rather than the classification of a group.

A trust arrangement involves the legal setup of a trust to hold and manage assets on behalf of beneficiaries, rather than simply naming them. While a trust can include contingent beneficiaries, the term does not specifically describe the act of naming a group like 'all of my children'.

A successive beneficiary is one who will receive benefits only after the prior beneficiary has passed away or is otherwise unable to inherit. This concept does not apply to class designations, which encompass all members of a defined group, regardless of individual circumstances.
