Ordered that the order is affirmed, with costs.
A stipulation of settlement in a matrimonial action is a contract subject to principles of contract interpretation ( see Rainbow v Swisher, 72 NY2d 106, 109; Perry v Perry, 13 AD3d 508, 508-509; Douglas v Douglas, 7 AD3d 481, 482). Where the stipulation is clear and unambiguous on its face, the intent of the parties must be gleaned from the four corners of the instrument, and not from extrinsic evidence ( see Rainbow v Swisher, supra; Sieratzki v Sieratzki, 8 AD3d 552, 553-554). Although partial performance of an oral modification of an agreement may render the modification enforceable ( see Rose v Spa Realty Assoc., 42 NY2d 338, 341; Richardson Lucas, Inc. v New York Athletic Club of City of NY, 304 AD2d 462, 463), the defendant former wife failed to establish that such an oral modification occurred in the instant case. Therefore, the Supreme Court properly granted the plaintiff former husband's motion to compel the sale of the former marital home pursuant to the parties' stipulation of settlement.
The appellant's remaining contentions are without merit.
