In many cases when parents divorce, decisions related to child custody and visitation are made by a family law judge. Once child custody and visitation orders have been established it is then the responsibility of both parents to follow the orders. Additionally, both parents are responsible for their actions and behaviors with regard to how they communicate and attempt to co-parent with an ex-spouse.
Unfortunately, some divorced parents are not able to move beyond their own hurt and negative feelings towards an ex-spouse for the sake of a shared child. As a result, a child may become the victim of what's known as parental alienation the results of which, for both a child and parent, can have long-term emotional and psychological repercussions.
