Samuel D. Ingham, a court-appointed attorney who has represented Britney Spears for the entirety of her almost 13-year conservatorship, has submitted a petition to resign from his position, according to a court filing obtained and dated Tuesday by CNN.

In the filing, Ingham stated that the resignation would be effective upon the designation of new court-appointed counsel for Spears.

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

At a court hearing last month, Spears gave dramatic testimony about how she has felt living under the arrangement, calling it “abusive” and asking Judge Brenda Penny to allow her to retain her own counsel and calling on the court to bring the conservatorship to an end.

CNN reported earlier Tuesday that Spears’ manager of 25 years, Larry Rudolph, also submitted a letter of resignation, citing the singer’s desire to retire.

The next court hearing for the conservatorship is scheduled for July 14.
