Dennis D’Alessandro, Dewey & LeBoeuf’s former chief operating officer, is challenging a trustee who is seeking about $9.3 million that Dewey paid to D’Alessandro before the law firm collapsed.

Alan Jacobs, the liquidating trustee of Dewey, sued D’Alessandro in March, claiming an employment contract providing D’Alessandro with a fixed salary, fixed bonuses, discretionary bonuses and trust payments was “an astronomically generous arrangement for a law firm administrator.” The complaint said the transfers to D’Alessandro were not in good faith, as they were made by an insolvent partnership to an officer or director.
