Revise parenting laws involving the best interest of a child who is transitioning genders

This bill amends Montana's child custody laws to establish specific guidelines for parenting decisions involving children who are transitioning genders. It requires courts to treat a parent's active support of a child's gender transition as not being in the child's best interests, while also stating that opposing a child's transition may not be considered against the child's best interests. The legislation adds these gender transition factors to the list of considerations judges must evaluate when determining custody arrangements, effective immediately upon passage.
