Most mediations involve an hourly or per-session fee, except for those that are ordered by a court or conducted through a community-based mediation agency. These agencies may provide mediation at a reduced cost or even for free. The number of sessions needed to gather information and negotiate an agreement will vary from couple to couple, so the cost of the mediation will also vary. Mediation, however, will usually be much less costly than adversarial litigation. A divorce mediator in private practice might charge anywhere from $100 to a couple of hundred dollars an hour, depending on where the mediator practices.
