A Westchester County woman who shepherded her young son to forensic psychologists in what a court said was a concerted effort to undermine his relationship with his father, and paid a former soap opera actress $57,000 to prep her for a “role” as a witness, has been stripped of custody.

Supreme Court Justice John Colangelo’s (See Profile) 40-page decision, which followed an 18-month trial that included 25 days of testimony by the mother, concluded that the woman was so fixated on undermining the father that she “cannot be trusted” to make dispassionate decisions regarding the boy who has been at the center of an epic custody battle for seven of his nine years.
