Despite numerous reforms over the years, intestate succession rules continue to privilege traditional, white, heterosexual families. It is evident that the one-size-fits-all scheme cannot truly reflect diversity of lifestyles and associations. This Article considers an innovative option that has become increasingly popular in recent years: using big data to create personalized rules, tailored to the personal characteristics of each decedent. This Article explores the promise and drawbacks of personalized intestacy, arguing that personalized default rules fall short in the realm of inheritance, because these rules are personal and inheritance law is inherently relational. It then offers preliminary guidelines for adapting big data techniques to the relational aspects of inheritance.
I use this framework to expand the study to critically evaluate other rules that can be personalized in the family: marital property division, will interpretation, and cohabitation.
