The petition for both a name change and a new birth certificate reflecting her new gender identity was filed with the Los Angeles County Superior Court in Santa Monica in April. It came to light recently in some online media reports.
The former Xavier Alexander Musk, who recently turned 18, the age of consent in California, has asked the court to change her gender recognition from male to female and to register her new name, according to court documents available online through PlainSite.org.
Her new name was redacted in the online document. Her mother is Justine Wilson, who divorced Musk in 2008.
There was no further explanation of the rift between Musk’s daughter and her father, the Tesla and SpaceX chief who is attempting a $44 billion takeover of social media platform Twitter.
Neither a lawyer who represents Musk nor the Tesla media office immediately responded to Reuters emails requesting comment on Monday.
