Unfortunately you do not explain what "dropping the ball" means.
I understand that you filed a legal malpractice against your first lawyer for doing something or not doing something that lead to the loss of your house. In order to win the malpractice case against the first lawyer your new lawyer would have to show the error the first lawyer made and must demonstrate you would have won that claim. Now you say your new lawyer "dropp[ed] the ball" and I assume you mean the legal malpractice case he filed cannot go forward.
Just like the first case, in order to be successful in a legal malpractice case against this new lawyer you will need to prove he made errors that prevented you from winning the first case. YOu will need to show that had he done everything right you would have won the malpractice case and also that you would have one the original underlying case.
Often legal malpractice cases are described in this way: YOu have to prove a case within a case. YOu have to prove the original lawyer would have one the case if the lawyer acted properly.
It looks like in your case you will need to prove a case within a case within a case.
