(a) In a custody proceeding, a court shall take into account the training as required by § 36-6-702.

(b) In a proceeding in which a court makes a custody determination, the court shall not order reunification treatment to reestablish a relationship with a parent or caregiver if a court has made findings against the parent or caregiver under § 36-6-406(a) or (c) or § 37-1-102(b)(28) unless the court finds that reunification efforts are in the best interest of the child.  The court shall file written findings of fact that are the basis of its conclusions on that issue in the order addressing reunification.  An order of reunification must not cut off contact with a parent who is non-abusive.

(c) In any proceeding in which a court makes an initial custody or custody modification determination after a court has made findings against a parent or caregiver under § 36-6-406(a) or (c) or § 37-1-102(b)(28), the court shall not issue an order restoring parenting time of the child to the parent or caregiver unless the court finds that the child will not be subject to further abuse or harm.  The court shall file written findings of fact that are the basis of its conclusions on that issue in the order addressing parenting time.

(d) In a proceeding in which the court has made a finding against a parent under § 36-6-406(a)-(d), the court shall include in the custody order written findings of fact that are the basis of its conclusions in regard to decision-making pursuant to § 36-6-407.
