Ingham was first appointed by the Los Angeles County Superior Court to represent Spears in her conservatorship when it began in 2008.

At a court hearing last month, Spears gave dramatic testimony about the conservatorship, calling it "abusive" and asking Judge Brenda Penny to allow her to retain her own counsel and terminate the conservatorship.
