The push to persuade Dewey & LeBoeuf partners to sign on to a proposed $90.4 settlement plan continued Thursday, with the defunct firm’s advisers offering up several modest incentives in what appeared to be a final bid to winning enough support for the settlement to succeed.

The latest revision to the so-called partner contribution plan came a day after a group of retired LeBoeuf, Lamb, Greene & MacRae partners as well as spouses of deceased retirees asked Manhattan Bankruptcy Judge Martin Glenn to put Dewey’s Chapter 11 bankruptcy in the hands of either a trustee or an independent examiner to ensure the fairness of the proceedings.
