Within five days of notice of the appointment, or within five days of notice of a subsequent dispute between the same parties, the parenting coordinator shall meet with the parties together or separately and shall make a diligent effort to facilitate an agreement to resolve the dispute. The parenting coordinator may confer with the parties through a telephone conference or other means. A parenting coordinator may make a decision without conferring with a party if the parenting coordinator makes a good-faith effort to confer with the party. If the parties do not reach an agreement, the parenting coordinator shall make a decision resolving the dispute as soon as possible but not later than five days after receiving all of the information necessary to make a decision and after the final meeting or conference with the parties. The parenting coordinator shall put the agreement or decision in writing and provide a copy to the parties. An agreement of the parties or a written decision of the parenting coordinator is binding on the parties until further order of the court.
