Parenting coordinator (PC) is a relatively new practice used in some US states to manage ongoing issues in high-conflict child custody and visitation cases by professional psychologist or a lawyer assigned by the Court. There are 10 states as of May 2011 that have passed legislation regarding parenting coordinators: Colorado (since 2005), Idaho (2002), Louisiana (2007), New Hampshire (2009), North Carolina (2005), Oklahoma (2001), Oregon (2002), Texas (2005), and Florida (2009). Legislation has been pending in Massachusetts for many years without significant progress.
In September 2014, the Massachusetts Supreme Judicial Court addressed the issue of whether the trial judge had the power to appoint a parenting coordinator without consent of both parties and to give the parenting coordinator binding authority to decide all matters brought before her. The Massachusetts Supreme Judicial Court ruled that the trial judge lacked the power to appoint the parenting coordinator without consent of both parties, and that the broad authority given to the parenting coordinator by the trial judge constituted "an unlawful delegation of judicial authority." Consequently, the Supreme Judicial Court vacated the appointment order.
