Profex, Inc. v Town of Fishkill, 2009 NY Slip Op 06320 (App. Div., 2nd, 2009)
"[T]he rule of accord and satisfaction has generally been accepted as a legitimate and expeditious means of settling contract disputes" (Horn Waterproofing Corp. v Bushwick Iron & Steel Co., 66 NY2d 321, 325). The party asserting the affirmative defense of accord and satisfaction must establish that there was a disputed or unliquidated claim between the parties which they mutually resolved through a new contract discharging all or part of their obligations under the original contract (see Merrill Lynch Realty/Carll Burr, Inc. v Skinner, 63 NY2d 590, 596; Pothos v Arverne Houses, 269 AD2d 377, 378; Trans World Grocers v Sultana Crackers, 257 AD2d 616, 617). The defendants established their respective entitlement to judgment as a matter of law on the basis of an accord and satisfaction (see Winegrad v New York Univ. Med. Ctr., 64 NY2d 851). In opposition, the plaintiff failed to raise a triable issue of fact (see Zuckerman v City of New York, 49 NY2d 557).
The bold is mine.
