Gov. Martin O'Malley is calling on mortgage servicers to voluntarily halt foreclosures in Maryland until they're certain they're following state law and can ensure residents aren't being mistreated. Shaun Adamec, a spokesman for Gov. Martin O'Malley, said the governor also is investigating whether the state could force a temporarily freeze on foreclosure proceedings. He was responding to a request by Congressman Elijah E. Cummings, who wants to see a moratorium for at least 60 days to determine whether lenders are starting cases to take back homes without confirming that the required legal documents are in order. Cummings, a Democrat from Baltimore, sent a letter over the weekend to O'Malley and Maryland Attorney General Douglas F. Gansler that referred to reports of some bank executives "signing affidavits and other legal documents in bulk without confirming the accuracy of the information."
