Dear Ms Preeti,
I wish to response but i believe you should repost your query after re drafting, as there is some ambiguity in the same. It would be really helpful if you repost your message. Please specify your exact query at the end.
By what appears from your query, there are a few things which I would say. First the marraige is void as per the Hindu Marraige Act. Secondly your son can be in trouble if he continues to behave in the manner in which you have written.
The legal situtation and implecations can only be discussed on your response.
