Is liye maine use ghar aneke liye ek notice bheja to uske jawab me usne notice ka jawab diya hai jisme mere Ma Baap par zuta Domestic violence ka iljam lagaya hai,she wants leave separate. Sanded second notice jisme pahle notice me kiye huye iljam mai sabut ke sath such kar sakta huan.[ I have Video recording of 2 family meetings]. Iska jawab usne notice period khatma hone ke bawajud abhitak nahi bheja(20 days).
