I recently attended a wonderful training on parental alienation and would be happy to share some of what I learned, which helps to explain why Dads so often end up on the losing end of parental alienation. The training was for attorneys and mental health professionals and gave great info on how attorneys can help a Dad (or in fewer cases, a mother) get it across to the courts that alienation is taking place.
I realize I'm a female and that may be suspicious to many, BUT, I am a private Guardian ad Litem in family court custody cases and I operate a supervised < parenting time > program...believe me I see how easily women can hijack the system. In my supervised < parenting time > program I am running 10 to 1 male to female clients, and the majority of my guardian ad litem cases are a Dad that can't get a step ahead of a scorned ex who has successfully commandeered the 'system'.
I do this because I do care about kids and find it repugnant when a parent , typically a mother, destroys a child's relationship with the other parent. The Dad pays a high cost indeed, but the child lives with the scars and dysfunction and never knows why. Ought to be criminal.
