Some co-parenting arrangements involve ongoing, low-level disagreements that are too frequent and too minor, individually, to justify a return to court every time, such as which weekend a schedule swap happens, how a minor medical decision gets made, or how a disputed pickup time is resolved. A parenting coordinator is a role designed specifically for that gap.
What the role is
A parenting coordinator is typically a mental health professional or attorney with specific training, appointed either by court order or by both parents' agreement, to help resolve disputes about implementing an existing parenting plan. According to guidelines published by the Association of Family and Conciliation Courts and the American Psychological Association, the role is generally limited to disputes about how an existing order or agreement is carried out, not to changing custody, decision-making authority, or the substance of the underlying order itself, which remains the court's role.
How it differs from other roles
A parenting coordinator is not a therapist providing treatment, though many have a mental health background; the role is structured around resolving specific disputes rather than providing ongoing counseling. It is also not a judge: depending on the jurisdiction and the terms of the appointment, a parenting coordinator may make binding recommendations on minor implementation disputes, non-binding recommendations that either parent can bring to court, or purely facilitate an agreement between the parents. The scope of authority is set by the order or agreement that creates the role and varies by state and by case.
Why this exists as its own role
Parenting coordination developed specifically to address high-conflict co-parenting situations where minor disputes were recurring often enough to overwhelm both the parents and the court, and where a faster, less formal resolution process could reduce the ongoing conflict a child is exposed to. It is generally not appropriate for disputes involving safety concerns, which belong in front of the court directly.
Where this fits into a case
Whether a parenting coordinator is available or appropriate in a given case, what authority one would have, and how one gets appointed all depend on the jurisdiction and the specifics of the case. These are questions a licensed family law attorney can address directly.
