The court may refer the parties to mediation at any time after a petition is filed if mediation services are available at a reasonable fee or no cost, and may require that the parties have made a good faith effort to mediate the issue before holding a hearing. An agreement reached by the parties through mediation on an issue must be reduced to writing, signed by the parties and presented to the court for approval as a court order. [PL 2017, c. 402, Pt. A, §2 (NEW); PL 2019, c. 417, Pt. B, §14 (AFF).]
