Bank of America and JPMorgan Chase will finally put to rest bills that are still alive on credit reports although legally eliminated in bankruptcy — potentially providing relief to more than a million Americans. The move is a victory for borrowers whose credit reports have been marred as a result of the reported debts, imperiling their job prospects and torpedoing their chances of getting new loans. The change by the banks emerged this week in Federal Bankruptcy Court, where the two banks, along with Citigroup and Synchrony Financial, face lawsuits accusing them of deliberately ignoring bankruptcy discharges to fetch more money when they sell off pools of bad debt to financial firms. Lawyers for Citigroup indicated that they were also considering a similar change.
