The Illinois attorney general's office filed mortgage rescue fraud lawsuits Tuesday against four Chicago-area companies, some employees and several attorneys, alleging that they illegally charged consumers for loan modification services that were not provided. The companies named as defendants in the suits were ZeTrust Legal Services, Chicago; Legal Modification Network LLC, Woodridge; Loan Litigators International LLC, which has gone out of business but was based in Lombard; and Exelpol Management & Consulting Inc., a defunct company that operated out of Schaumburg. The lawsuit was filed in Cook County Circuit Court.
