As yet another example of why legal malpractice is a difficult discipline, here is a case in which there was a failure to file a counterclaim, The legal malpractice case ends in dismissal, because the Appellate Division determines that the counterclaim, even if made would have failed. Ginther v Rosenhoch ;2008 NY Slip Op 10292 ;;Appellate Division, Fourth Department
 

"One necessary element of such a cause of action is that, " but for the [defendants’] negligence, the plaintiff[] would have been successful in the underlying action’ " (Oot v Arno, 275 AD2d 1023, 1023). Here, plaintiff alleges that defendants committed legal malpractice by, among other things, failing to assert a counterclaim in the underlying action, for recovery of premiums paid by plaintiff under a disability insurance policy. We note, however, that the Second Circuit affirmed the judgment of the District Court in favor of the plaintiff insurer in the underlying action on the sole ground that the claim for benefits made by defendant, the plaintiff herein, was untimely under the policy (Provident Life & Cas. Ins. Co. v Ginther, 51 Fed Appx 72). Thus, it cannot be said that, but for defendants’ negligence, plaintiff would have been successful on a counterclaim for recovery of premiums in the underlying action (see Oot, 275 AD2d 1023).
