A trustee is asking a New York bankruptcy judge to slash fees of Weil, Gotshal & Manges and other law firms, criticizing their billing tactics and invoices in the ongoing reorganization of a mortgage origination and servicing business.

The fee applications in the Chapter 11 case of Ditech Holding Corp. “reflect numerous instances of questionable billing judgment and overstaffing,” said the U.S. Trustee’s Office in New York in Dec. 5 court papers.
