Elon Musk’s 18-year-old transgender daughter says she doesn’t ‘wish to be related’ to the billionaire in a petition to change her name and gender.

According to court documents filed on April 18 from the Los Angeles County Superior Court in Santa Monica, obtained by USA TODAY, Musk’s 18-year-old daughter said in the petition for a new birth certificate that the decision to change her name was twofold: To reflect her gender identity and because, “I no longer live with or wish to be related to my biological father in any way, shape or form.”

Musk’s daughter’s previous name reflected on her birth certificate was formerly Xavier Alexander Musk. Filed by Xavier Alexander Musk in Los Angeles County Superior Court shortly after her 18th birthday, the April 18 petition seeks the legal change of her name to Vivian Jenna Wilson (the maiden name of her mother, Justine Wilson); recognition of her gender as female; and the issuance of a new birth certificate to reflect the changes.

Vivian is one of five children shared between Justine, a 49-year-old Canadian author, and Musk, 50. The couple married in 2000 and divorced in 2008.
