My cousin brothers wife is cheating him and going around with another man (also married) for past two years. Despite counselling by family members, she isn't ready to stop. She is now threatening my cousin of dire consequences and is demanding money. She doesn't want to stay with my cousin any more and is asking my cousin to rent a seperate house for her and their child (5 year old son). My cousin lives in a joint family with his married brother, brother's wife, brother's daughter and their mother and grand mother. They all live in Mumbai. Even my cousin doesn't want to continue with the marraige and is ready for a divorce.
Off late the woman creates a rucus in the house almost daily by hurting and injuring herself using various dirty methods. She is threatening of framing my cousin, his mother and brother for domestic violence in addition to demanding money and a rented house for her and maintenance for their son.
In the circumstances, what is the immediate legal remedy to my cousin and his family members as a preventive measure from getting trapped in a domestic violence case? Please advice.
