Five Maine residents filed a complaint today against GMAC Mortgage. The complaint was filed on behalf of the five residents and a class of Maine residents who allege the company “routinely and systematically” approves false affidavits. Ally Financial said it does not comment on pending litigation. The Maine residents are represented by Andrea Stark from the Molleur law firm, Thomas Cox coordinator of Maine Attorneys Saving Homes, the National Consumer Law Center and the Center for Responsible Lending. The firm has been the epicenter of the robo-signing scandal that revealed servicers within the firm signed foreclosure documents without reviewing them or without a notary present. GMAC announced last week it was halting foreclosures in 23 states so it could review past filings. On Wednesday, JPMorgan Chase announced it too was looking into potential robo-signing within its services. Since then, attorney generals in California, Connecticut, Florida, Ohio, Colorado and Illinois have either asked to halt foreclosure actions or launched investigations into servicing processes across their respective states. The acting chairman of the Office of the Comptroller of the Currency Friday ordered Bank of America (BAC), JPMorgan Chase (JPM), Citigroup (C), HSBC Financial Corp. (HTB), Wells Fargo (WFC), PNC Bank (PNC) and U.S. Bank (USB) to review their foreclosure processes for any sign of fraud. Write to Christine Ricciardi.
