Frederick v Meighan ; 2010 NY Slip Op 06076 ;Decided on July 13, 2010 ;Appellate Division, Second Department is a case in which Supreme Court dismissed, sua sponte on the basis of statute of limitations, the Appellate Division reversed. 

When does the statute of limitations start to run in legal malpractice?  The easy answer is as of the date of the mistake, or, with continuing representation, on the last day the attorneys represent plaintiff.  But, the more complex answer is on the day that a cause of action for malpractice comes into existence.  It may be years later than either of the first two dates.  Here, the cause of action did not come into existence until the Appellate Division ruled in the underlying case.

"Following this Court’s decision on the appeal in the underlying action and the subsequent award of damages to the buyers, the plaintiff commenced this action against the Meighan defendants and the DeCaro defendants to recover damages for legal malpractice. As against the Meighan defendants, the plaintiff principally alleged that the inclusion of the executed construction agreement in the package of documents sent back to the buyers’ attorney constituted legal malpractice, as it enabled the buyers to obtain specific performance of the contract of sale (see Suchin v Frederick, 30 AD3d 503). As against the DeCaro defendants, the plaintiff principally alleged that their failure to interpose a rescission defense based upon mistake in the underlying action constituted legal malpractice. In addition, the plaintiff alleged that the DeCaro defendants’ failure to advise him of a potential legal malpractice claim against the Meighan defendants and to interpose a legal malpractice cross claim against them in the underlying action constituted legal malpractice.

At the outset, we find that the Supreme Court improvidently exercised its discretion in, sua sponte, directing dismissal of the complaint insofar as asserted against the Meighan defendants pursuant to CPLR 3211(a)(4) in view of the continued pendency of the first legal malpractice action against those defendants, which relief was not requested by any party in this action (see Clair v Fitzgerald, 63 AD3d 979, 980; Frankel v Stavsky, 40 AD3d 918, 919).

We further find that the Supreme Court should have granted that branch of the plaintiff’s motion which was for summary judgment on the issue of liability against the Meighan defendants. In order to prevail in an action to recover damages for legal malpractice, a plaintiff must establish that the defendant attorney failed to exercise the ordinary reasonable skill and knowledge commonly possessed by a member of the legal profession, and that the breach of this duty proximately caused the plaintiff to sustain actual and ascertainable damages (see Rudolf v Shayne, Dachs, Stanisci, Corker & Sauer, 8 NY3d 438, 442).
 

Contrary to the Meighan defendants’ contention, inasmuch as the plaintiff did not sustain "actionable injury" until this Court awarded the buyers specific performance in the underlying action, the plaintiff’s legal malpractice cause of action against them was not time-barred (McCoy v Feinman, 99 NY2d 295, 301; see Kerbein v Hutchison, 30 AD3d 730, 732).
