A child-custody litigant is asking New Jersey’s Supreme Court to set aside an order that he pay $51,000 to a parenting coordinator — most of it for time she spent responding to his grievances about her performance.

Moses Segal claims in his petition for certification, in Segal v. Lynch , A-2134-09, that such charges were not contemplated by the Supreme Court when it launched the pilot Parenting Coordinator Program in 2007.
