How do i expose a sociopath in court for custody?

You can describe the behaviors that concern you, but the best way to expose a mental or personality disorder is through expert testimony. You have the right to seek a court order forcing him to be evaluated, but you will likely have to pay for it and the costs can be substantial.

It would be in your best interest to retain an experienced custody lawyer in your jurisdiction who can give you specific legal advice. It may be in your best interest to file a petition to modify custody and request a custody evaluation that would assist in determining what is the issue with your child's father. It is not enough for you to believe that he is a sociopath. You would have to have an expert witness (a psychologist who does the custody evaluation) testify as to the diagnosis if any of the father.

In addition to have the father be evaluated for a custody evaluation, if your son is exhibiting any form of mental or physical issues from the father's behavior, this must be documented and provided to the Court when you have your Court hearing. Also, you should bring your son to the Court hearing in the event the Judge wishes to interact with him.
