Billionaire Elon Musk’s transgender child has filed a request for a name change over gender identity in an effort to cut ties with their father. “Gender identity and the fact that I no longer live with or wish to be related to my biological father in any way, shape or form,” Musk’s child gave as reasoning for the petition.

According to Fox News, Musk’s child has asked for both a name change and a new birth certificate reflecting a new gender identity. The request was filed in April with the Los Angeles County Superior Court in Santa Monica. Xavier Alexander Musk just recently turned 18 and has asked the court to recognize the gender change from male to female and to register a new name, according to court documents.

The new name would be Vivian Jenna Wilson, taking the mother’s last name, TMZ reported. Musk’s child said that “she wants to be recognized as female,” according to the outlet. The teen’s mother, Justine Wilson, divorced Musk in 2008. There were no further details provided of the tensions between Musk and his child. There were no further details provided of the tensions between Musk and his child.
