My question involves bankruptcy in the state of: Maryland

My sister has an ongoing case. The lawyer took her money, got her to court, told her that after he last payment her case would be final then everything was thrown out because the lawyer did not include her husbands ground rents which he has not collected from in two years because people wont pay.

The Lawyer was aware he had them, but did not include them in their case. She was told by another lawyer after obviously firing this one that she can be locked up for fraud. How is this so when the error was on the lawyers end?

Any help or advice would be great.
