Property depute between mother and son.

I worked in gulf and send money to purchase a land which was was registered in my mother's name because I was unable to come to India at that time. Now I am back and I ask her to register it back to me but she is refusing. She is clinically depressed and my sisters are emotionally manipulating her to divide and equally among me and my 4 sisters 1 is married and three are unmarried. Or sell the land and divide the among me and my 4 sisters. My mother has 4 more properties in her name. Call me.pls
