Although a string of law firms have filed for bankruptcy in recent years, Dewey & LeBoeuf last week became the largest to file for Chapter 11, and the case raises novel issues for creditors and the courts, bankruptcy lawyers say.

The departure of the management team along with nearly 300 Dewey partners left the firm’s general counsel Janis Meyer and executive partner Stephen Horvath to wind down operations. Dewey has retained Albert Togut, a bankruptcy partner at Togut Segal & Segal. Joff Mitchell, a senior managing director of Zoflo Cooper, said in an e-mail that he is the firm’s chief restructuring officer.
