If a trust provides for one or more successor beneficiaries after the death of the settlor, the trust is not invalidated, merged or terminated because:
1. There is one settlor who is the sole trustee and the sole beneficiary during the lifetime of the settlor; or
2. There are two or more settlors, one or more of whom are trustees, and the beneficial interest in the trust is in one or more of the settlors during the lifetime of the settlors.
