Defendant's factual opposition to plaintiffs motion on the account stated cause of action with respect to the arbitration proceeding, which consisted entirely of one sentence stating that he objected often to plaintiffs conduct of the proceedings and the amount of plaintiffs bills, is insufficient to raise a genuine issue of fact, in view of the overwhelming evidence of defendant's recognition of his obligation to pay plaintiff the entire amount of the 18 invoices in question, including his partial payment of the invoices accompanied by a promise to pay the balance ( see, Shea Gould v Burr, 194 AD2d 369, 371). Nor is there merit to the defense and counterclaim for legal malpractice, which, at best, allege nothing more than an error of judgment in recommending certain litigation ( see, Rosner v Paley, 65 NY2d 736). We have considered defendant's remaining contentions and find them to be without merit.
