The Court of Appeals has historically applied the principles of contract construction and interpretation to marital agreements (Graev v. Graev, 11 N.Y.3d 262 (2008); Meccico v. Meccico, 76 N.Y.2d 822 (1990); Rainbow v. Swisher, 72 N.Y.2d 106 (1988)), which includes the six-year limitations period in CPLR 213(2), "an action upon a contractual obligation or liability, express or implied."
