Britney Spears’ new lawyer has asked a court to speed up a hearing on whether to remove her father Jamie from her conservatorship.

Mathew Rosengart filed new legal documents on Thursday requesting that the next hearing date in Britney's long-running conservatorship case be moved up from September 29th to August 23rd, arguing that "every day matters."

"Every day that passes is another day of avoidable harm and prejudice to Ms. Spears and the Estate," Rosengart said in the filings. "There has been an evident dissipation of assets of Ms. Spears’ Estate, and that dissipation is ongoing."

Rosengart also claimed that Jamie had 'grossly overpaid' Britney's former business manager, Tri Star Sports and Entertainment. According to the filings, Jamie Spears paid the firm $500,000 in December 2019, $300,000 more than was supposedly due, even after the singer had taken a hiatus from performing that year.

"An investigation is warranted but can only commence fully once Mr. Spears is removed," Rosengart wrote.

He also requested that the judge suspend Jamie from Britney's conservatorship at the earliest date possible, if the hearing date could not be altered.

Rosengart, who Britney was permitted to appoint as her legal representation last month, filed a petition on July 26th to remove Jamie Spears as the conservator of his daughter's estate.

Britney's caretaker Jodi Montgomery has lent her support to this petition, and also claims that her medical team are in favour of Jamie's removal too.
