Last Fall I wrote several posts ( here and here) on a one portion of the causation issue in legal malpractice cases.
A summary of my view: I believe that a plaintiff in a legal malpractice case arising out of a claim that a personal injury case was mis-handled must prove that amount of damages that would have been collectible in the underlying tort case. First, the plaintiff would ordinarily prove the amount of liability insurance, if any, available to the original defendant. Second, if the plaintiff wants to collect a judgment more than the amount of the liability insurance originally available, he or she should have to prove that it was more likely than not that the plaintiff could have collected more than that amount from the tortfeasor. This will require proof of the income, assets and liabilities of the original defendant. In appropriate cases, the lawyer defendant will want to demonstrate that the income, etc. of the original defendant is such that the plaintiff cannot prove that the judgment would not have been collectible above the amount of liability coverage or that the evidence offered is insufficient to prove that any monies could have been obtained over and above the insurance monies.
I think the burden of proving collectibility should be on the plaintiff because it should be deemed part of the causation argument. More specifically, the plaintiff has to prove damages by reason of the alleged malpractice of the lawyer. (The lawyer failed to have process re-issued in a timely fashion, and the case was dismissed with prejudice). That means plaintiff must prove that what damages, if any, he would have been able to collect in the underlying tort action against the original defendant. The plaintiff should not be able to collect more damages from the lawyer defendant that he would have been able to collect against the original defendant. What the plaintiff lost was the right to proceed to trial against the original defendant, and therefore what he should be able to collect from the lawyer is what he could have collected from the original defendant.
