Geraldine Wyle, an attorney for Jamie Spears, wrote that Lutfi and Ghalib have "disappeared," and private investigators had been trying to find the pair unsuccessfully for six weeks.
This week, the documents state, an attorney sent a proposal to remove Spears' court appointed attorney. He later told Spears' attorneys that he had been contacted by Eardley and Lutfi, according to the filings. The documents were never filed with the court, and that attorney dropped Lutfi and Eardley as clients, the documents state.
Eardley once claimed to be Spears' attorney and tried to get her conservatorship case moved to federal court. A phone message left at Eardley's office was not returned Friday.
Spears and her father agreed not to renew a temporary restraining order that was issued against Lutfi last year when it expired in July.
At the time, Spears' court-appointed attorney Samuel D. Ingham III issued a statement renouncing their friendship. "Britney has made clear to everyone that she does not want to be further hara**ed or contacted in any way by Osama 'Sam' Lutfi, now or at anytime in the future," Ingham said in a statement.
Lutfi at the time declined to comment, saying only that he and Jamie Spears had reached an agreement.
That arrangement called for Lutfi to have no contact with Britney Spears or her parents, according to details released Friday.
Spears was placed under the conservatorship a year ago on Sunday. The arrangement has been expensive her estate has paid out hundreds of thousands of dollars in legal fees but since her father took control of her life, the pop singer has not had the bouts of erratic behavior, including two hospitalizations, that led to his intervention.
She released her newest album, "Circus" in December on her 27th birthday and is preparing for an upcoming concert tour.
