Whether an emancipation event occurred was an issue properly determinable upon a mistake of fact proceeding (Zuckerman v Zuckerman, 154 A.D.2d 666). As separation agreements are subject to the same rules of contract construction and interpretation as other agreements (Matter of Baker v Baker, 33 A.D.2d 812), the court properly considered the plain meaning of the agreement in treating each of the specified "Emancipation Events" as separate and independent (22 N.Y.2d Jur 2d, Contracts, § 188, at 22). Thus, the 18-year-old son's voluntary termination of his permanent residence with his mother constituted an emancipation event, triggering a reduction in defendant's maintenance obligation. The court also properly imposed a sanction of counsel fees upon plaintiff for frivolous conduct consisting of outright misrepresentation in respect to the motion for reargument when, on the original motion, plaintiff clearly waived the relief of a proffered hearing and insisted that the court proceed solely upon the papers submitted (Rules of Chief Administrator of Courts, 22 NYCRR 130-1.1).
