My ex and I have counter Domestic Violence Order ( DVO) on each other. In them, it stipulates that he can contact me with regards to the children and only the children. Can I record the conversations they have, as they are most of the time my ex trying to tell my kids that I am a bad mother. He is their stepfather and they don't know their real father, however I think he is going to try and get some sort of visitation or custody of children. Am I legally allowed under family law to record the conversation?
