A Manhattan judge has refused to dismiss a legal malpractice suit against Phillips Nizer that alleges the firm failed to share information provided to an inexperienced attorney in a divorce case that would have altered litigation strategy.

Acting Supreme Court Justice Nancy Bannon said the firm’s former client, Elizabeth Berardi, has shown she has causes of action to recover for legal malpractice and negligent supervision and for a judgment declaring that the firm overbilled her by virtue of alleged malpractice.
