Parents have the responsibility to make decisions and perform other parental functions necessary for the care and growth of their minor children. In any proceeding between parents under this article, the best interest of the child shall be the standard by which the Tribal Court determines and allocates parental responsibilities. The Tribe recognizes the fundamental importance of the parent-child relationship and that the relationship between the child and each parent should be fostered unless inconsistent with the best interest of the child. The best interests of the child are served by a parenting arrangement that best maintains a child’s emotional growth, Tribal and cultural ties, health and stability, and physical care. Furthermore, the best interests of the child are ordinarily served when the existing pattern of interaction between a parent and child is altered only to the extent necessitated by the changed relationship of the parents or as required to protect the child from physical, mental or emotional harm.
