I am an adult male living with my family in a government provided quarter allotted to my mother. Until recently, my mother threatened me of eviction and verbally abused after a dispute over a small matter. I would to like to know whether it is an offense to threaten eviction of a family member or verbally abuse them and threaten to physically hurt them or not. Can I file an FIR or register a case diary against this, and if so, under what laws, provisions and/or articles? Can another family member's witness be taken into account for the purposes of examining? Also, is a written deposition of witness by neighbors acceptable?
