The New York investigation appears to center on two of the state’s foreclosure industry giants: the Steven J. Baum firm, headquartered in Amherst, N.Y., and Pillar Processing, a default servicing firm set up by Mr. Baum that was spun off in 2007. Representing JPMorgan Chase, Wells Fargo and other large banks, the Baum firm has handled an estimated 40 percent of foreclosure cases in the state. Pillar Processing provides extensive services to the firm.
