@Palak, experts have advised you as per best of their knowledge, legal preposition and social standing wherein you are dissatisfied, consequently you have some other query/problem as I observed, all through your post and expert's replies thereto.
You have made up your mind to get out of your matrimonial relation, where every one i.e., husband, mother-in-law, father-in-law, sister-in-law and their relatives in police including your parents etc. are on the other side of the fence, (reasons best known to you only which I feel you have concealed from posting here) in these circumstances you may proceed the way you decide but stop this thread.
