Son property rights to parents

The property lying in your name will be your own property, you may tell any reason that it does not belongs to you, but legally you are the owner.  However, your wife cannot dictate terms to order your parents or brother and his family to vacate because she has no right in it.  The law what you refer that will come into existence in future is not there at present hence do not worry about which is not there.  You wanted opinions from experts here but you have not asked for a specific relief you are looking for.  Your question concentrates on only justice to your parents.  You have to decide about what type of justice you want to give to your parents, since it is your house you do not have to allow your wife to dominate you to drive away your parents from your house, that way you be firm on your decision. If she is quarrelsome and seeking residential rights in the house, better execute a gift deed to your parents and you go and settle outside in a rented house and inform her to join you in your place of residence.  You have engaged a lawyer, take further advise from him on the subject.
