Even as Bank of America begins to restart foreclosure proceedings in 23 states Monday, the bank confirmed that it had discovered errors, including incorrect data and misspelled names, in the paperwork it has reviewed. For weeks, Bank of America has insisted its review had not turned up any serious errors and emphasized that it had not found a single case where a homeowner was facing foreclosure in error. But on Sunday, the bank revised its fairly combative public stance. Bank of America had found errors, but only in a tiny number of cases, Dan Frahm, a spokesman for the bank, said late Sunday. 'These are examples of exceptions that were caught early in the process through control steps,' Frahm said. 'They do not reflect exceptions in final documents that are being resubmitted to the courts.' Bank of America and several other institutions, including JPMorgan Chase and GMAC Mortgage, halted foreclosures in late September and early October amid a growing controversy over problematic documents, including so-called robo-signers -- bank employees who say they signed foreclosure affidavits without reviewing the documents. Other foreclosure cases were initiated with missing documents or incorrect information. As a result of its review, Bank of America has combined signing and notarization into one step, unlike in the past, when they were separate tasks. 'We felt there was greater risk for error before,' Frahm said. On Sunday, Bank of America maintained that no homes were foreclosed in error. 'The basis for our foreclosure decisions has been accurate,' he said, and he added that the bank would work to correct any problems. Initially, Bank of America imposed the freeze in 23 states where judicial approval is required before a foreclosure can go ahead, and the bank extended it nationwide on Oct. 8. But on Oct. 18, the bank confirmed foreclosures would resume in the initial 23 states and declared it was confident in the procedures it had in place.
