The Trial Court erred when it effectively changed physical custody based solely on an in camera interview with the children without making findings regarding whether the change would alter the established custodial environment and applying the appropriate burden of proof, whether modification was in the children’s best interests.

The trial court’s decision to suspend Mother’s parenting time had the effect of modifying the award of joint physical custody in the consent judgment of divorce, and MCR 3.207 did not apply to the case.
