I am embroiled in a property dispute with a family member. First, he slapped false 138 cases against me to pressurize me into withdrawing the legitimate property case. Now, not only he is threatening, over the phone, to harm me and my immediate family but also some elders in the family who are on my side. I even managed to tape record one of his phone calls in which recording he clearly says that either I withdraw the property case or he will have us harmed physically. What can I do with the recording - Can it be used as evidence?
