Here’s what that might look like: your spouse/s (your long-term partner/s, if you are unmarried, have no legal rights unless you grant it to them prior to your death), your children by majority vote, your parents, siblings, grandchildren, grandparents, nieflings, the siblings of your parents, and so on—there are rules for determining who’s next in line all the way down to your first cousins twice removed!

To my brother Michael, my sister-in-law Cathryn, and nieflings Peter, Daniel, and Clara: I love you and wish you many exciting adventures in the years to come.
