  Never had this thought but I’m with you, I’d really like to be able to legally add someone to my family
context: There is, it is called Adult Adoption. >
  
  Lemme ask my friend if i can adopt him >
  
  Just putting this out there, but if there is some rich person who wants to adopt an adult daughter for inheritance purposes.... I am here :p
  But yeah, it is pretty rare, and I think it is typically for legal issues such as leaving your money to non-family.  
  There was also a movie that had this theme.  Music in my Heart with Tony Martin. >
  
  If said rich someone also wants an adult son I am here! >
  
  Gonna be honest, it depends on how rich this someone is...
  If they are rich enough, hello brother! >
  
  I'm actually pretty into this.  Unexpected opinion I hadn't thought about,  but absolutely agree with.
