The U.S. Attorney’s office in Manhattan has entered into an agreement with the law firm of Steven J. Baum, one of the largest volume mortgage foreclosure firms in New York state, that requires the firm to pay $2 million to Uncle Sam and to extensively change its mortgage foreclosure practices. The agreement resolves an investigation into Baum’s mortgage foreclosure-related practices, specifically whether the firm, on behalf of its lender clients, filed misleading pleadings, affidavits and mortgage assignments in state and federal courts in New York.
