Grimes, Musk holding baby X on shoulders
Grimes and Elon Musk share three children, including a son known as X, who is 3.
  • Elon Musk and Grimes have filed parental-rights lawsuits against each other in different states.
  • If the case turns into a child support battle, Musk would be better off if it plays out in Texas.
  • The jurisdiction will come down to who can prove where the kids actually live, Texas or California.

Elon Musk and Grimes filed dueling parental rights lawsuits last month in Texas and California respectively — and depending on who prevails, the dispute could shape up to be one of the biggest child support cases of all time.
