Laws – New York law does not govern living wills. However, the Court of Appeals has determined that a living will is valid if it provides “clear and convincing” evidence of the principal’s health care wishes (Matter of O’Connor, 72 N.Y.2d 517, 531 N.E.2d 886 (1988)).
Signing Requirements – Not statutorily defined. It is recommended that a living will be signed by two (2) adult witnesses.
