The Eleventh Circuit has held that the filing of a bar complaint is not sufficient to demonstrate that prior counsel was notified of the allegations against him and given an opportunity to respond because not all bar complaints lead to a notice being sent to the attorney. In addition, the filing of a bar complaint is a separate requirement under Matter of Lozada from notice to the attorney, and permitting the bar complaint to serve as notice would eviscerate the separate requirement of a bar complaint.
