Claire Boucher, a musician known by her stage name Grimes, has sued Elon Musk over a matter regarding their three children.

Boucher filed a "petition to establish parental relationship" on Sept. 29, court records say. It amounts to a request for a court order that identifies the legal parents of a child and is often required when couples are unmarried. The actual filings are not visible to the public.

Family attorney Deborah Dubroff said the petition amounts to a lawsuit and is typically filed alongside demands for child support or custody rights.

"Most of the time, the driving force is that they need custody orders or child support, but the petition is to establish parentage of the child," Dubroff said.

There were no filings for child support or custody rights in the case as of Monday.

Boucher's attorney, Samantha Bley DeJean, did not respond to a request for comment.

Boucher and Musk never married and reportedly split in September 2021 after they began dating in 2018. Over the course of their relations, the couple had three children together, X Æ A-Xii, Exa Dark Sideræl Musk and Tau Techno Mechanicus.

Musk has been divorced three times and has 11 children, including five from a previous marriage: twins Griffin and Vivian and triplets Damian, Saxon and Kai.

Musk took control of social media platform X, formerly known as Twitter, in April 2022 after purchasing the company for $44 billion.

Since the platform's takeover, Musk has made several controversial changes, mostly notably changing its name to X, with Musk promising to turn the social media platform into the "everything app" encompassing communication, banking, streaming video, shopping and more.

Musk also got in trouble with the city over unapproved plans to put beds in offices and add a large, blindingly bright sign on top of X's San Francisco headquarters.
