It is very common after bankruptcy to have some creditors make errors in their reports to credit bureaus. That’s true of both chapter 7 and chapter 13. That usually seems to happen because of an unintended error but not always. There are businesses that actually specialize in purchasing debt that is known to have been discharged in bankruptcy. Why would they purchase debt that is legally unenforceable? Because the purchaser then reports the account to the credit bureaus as being owed and waits to try to collect it. When real estate was at its peak and people were refinancing at record levels, it was not unusual to have an account reported as owed which had been discharged in bankruptcy. Since removing the account from the credit report takes over a month, many people simply had the account paid at closing.
