Eric T. Schneiderman, the New York attorney general, has issued subpoenas to the state’s largest foreclosure law firm and a related company, indicating that his office has some doubts about the effort by state attorneys general to resolve questionable foreclosure practices among the nation’s top banks.
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.
