The idea of identifying a syndrome or mental disorder to explain the actions of extreme malicious behavior by parents during divorce arose from examples of vindictive parents in clinical and legal cases. Some of these behaviors include burning down the house of an ex-spouse, falsely accusing the other parent of abuse, or purposely interfering with planned parenting time.
In one particular example that could be called an instance of malicious parent syndrome, a mother told her children they could not afford food because their father had wasted all their money. In another, a parent repeatedly misinformed the other parent about school activities, so that the parent could not participate in the child’s school life. In all of these actions, the intent is to harm the other parent.
