    George H. Lamprecht, Jr., Plaintiff, v. Franklin Bien, Defendant.
    First Department,
    May 8, 1908.
    Evidence — negligence of attorney at law — proof of damage.
    A client suing his attorne)r at law to recover damages caused by negligence in prosecuting an action, is entitled to prove that he had a cause of action in the original case which the defendant undertook to prosecute and that but for the defendant’s negligence he would have recovered a judgment for a substantial amount, for the burden is on the plaintiff to show the actual damage suffered and the evidence is relevant on that question.
    Motior by the plaintiff, George H. Lamprecht, Jr., for a new trial upon a case containing exceptions, ordered to be heard at the Appellate Division in the first instance, upon the dismissal of the complaint by direction of the court after a trial at the New York Trial Term held in November, 1907.
    
      
      John T. Canavan, for the plaintiff.
    
      Franklin Bien, for the defendant.
   Clarke, J.:

This action was brought to recover damages against the defendant, an attorney at law, for his negligence in prosecuting an action at law on behalf of the plaintiff by reason whereof plaintiff had been deprived of the means of recovering and collecting his said demand. Upon the trial the plaintiff attempted to prove that he had a cause of action in the original case which the defendant had undertaken to prosecute for him, and but for the defendant’s negligence would have recovered a judgment therein for a substantial amount. The trial court excluded the evidence offered to sustain that contention and dismissed the complaint stating, “The principal ground on which the motion is granted being that the court did not deem it proper to try in this action the issues of the claim of Lamprecht against Mohr, or the estate,” and directed the exceptions to he heard in the first instance at the Appellate Division.

In Quinn v. Van Pelt (56 N. Y. 417) Rapallo, J., said : “ In such an action the onus is upon the plaintiff to prove the breach of the agreement and the amount of damages sustained by reason thereof, and that she can recover only the damages thus proved. * * * The measure of damages is not the amount of the fee which he •received. The damages may be more or less than the amount of the fee and the burden rests upon the, plaintiff to prove them and not upon the defendant to prove how much of his stipulated fee he actually earned.”

In Vooth v. McEachen (181 N. Y. 28) the trial court had charged : When negligence has been proved, if you find there was any in consequence of which a client has lost his case, it is not incumbent upon the client to show that hut for the negligence he would have succeeded in that action.” The Court of Appeals reversed because of this charge and, citing text books and cases, held that the damages recoverable are those shown to exist and that the burden of showing the amount of damage suffered rests upon the plaintiff. The plaintiff, therefore, being required to show the actual damage suffered, was deprived of the opportunity to do so by the exclusion of the only evidence available for that purpose. Such exclusion was error.

It follows, therefore, that the exceptions should be sustained and a new trial ordered, with costs to the plaintiff to abide the event.

Ingraham, McLaughlin, Laughlin and Scott, JJ., concurred.

Exceptions sustained and new trial ordered, with costs to plaintiff to abide event. Settle order on notice.
