Yvette Boronow v. Eugene Boronow

[71 N.Y.2d 284 Page 286] Opinion OF THE COURT We agree with the Appellate Division that a party to a concluded matrimonial action, who had a full and fair opportunity to contest title to the former marital home, is barred by res judicata principles from subsequently and separately reopening that issue. The discretionary authority reposed in the courts under Domestic Relations Law ? 234 is not to the contrary and may not be read as conferring unilateral and unfettered options on parties in this respect. We thus affirm.
