Part of your question deals with "removing" the judgment. That likely depends on when the judgment was entered. If the creditor entered the judgment after you filed for bankruptcy because it was unaware of the filing, your attorney out to be able to convince the creditor to remove it because it is void for violating the automatic stay.
Much will depend on the timing and whether the creditor was aware of the Your bankruptcy case. You mention that your attorney missed the judgment.
