Child Custody and Support - As enacted, requires a court to include written findings of fact as to whether certain limitations in parenting plans apply in a child custody order, whether temporary or permanent. - Amends TCA Title 29; Title 36 and Title 37.

HB 2127 requires Tennessee courts to give the highest weight to credible evidence of physical abuse, sexual abuse, or domestic violence when determining child custody. It applies this standard equally to abuse affecting any household member, including siblings, step-siblings, or foster siblings. The bill also creates a presumption that placing a child with a parent found to have committed such abuse is not in the child's best interest, requiring courts to provide written justification if they override this presumption. This law directly affects custody decisions in cases involving abuse allegations, amending Tennessee Code Sections 36-6-106 and 36-6-406.
