What is Parental alienation? Many characterize it as a form of child abuse in which one parent undertakes to manipulate children psychologically to reject the other parent. In Missouri, where joint legal custody and substantially shared custody and visitation plans are strongly favored, may give rise to the justification for the court to modify parenting time when one parent is, in this case, purposefully undermining the other parents’ relationship with the children. As such, even, generally speaking, Parents must be mindful to avoid any appearance of parental alienation. Then, those parents who are the subject of the alienation should seek help in remedying the situation before it could become too far gone.
