after partition in 1947 my father was alloted a house in his name by the government later on after the death of my father the property was trasfered in the name of my mother. I am the only daughter of my parents having 1 son and 3 daughters.in 2002 my son on its own without telling me and my daughters got the property trasfered to his name from my mother as gifted property and sold it to third party. my mother is still alive. there is no registration deed done yet in the name of third party.
now please suggest me what can i do..... is this a ancestral property ? what action can i take to take that property back. son has been disowned by me 7 years back in 2005.
