MEMORANDUM. The order of the Appellate Division should be affirmed. We agree that "[t]he obligation of the defendant, though consisting of two promises, is in truth a single obligation requiring the plaintiff to assert its full claim in one action. Failure to do so results in the splitting of a cause of action which is prohibited (Roe v Smyth, 278 N.Y. 364, 369; Columbia Corrugated Container Corp. v Skyway Container Corp., 37 A.D.2d 845, 846, affd 32 N.Y.2d 818)."
Accordingly, inasmuch as plaintiff did not assert its claim for expenses of collection and reasonable counsel fees in the first action, it is precluded from asserting them in a second, independent action.
Chief Judge BREITEL and Judges JASEN, GABRIELLI, JONES, WACHTLER, FUCHSBERG and COOKE concur.
Order affirmed, with costs, in a memorandum.
