My grandmother had 100cents of land.In 2006my grandparents dead. My father is the only son of my grandparents (no sisters or brothers). He has another two daughters for a seperate relation. After my grandparents death he transferred all propertis to (separate relation) other daughters without informing us (me and my sister, we are elder than other two daughters). Actually my grandma agreed me to give us her property share and my father also agreed verbally. Now we understand that even a single cents of land is not registerd for us. we are Hindus. what should we do for this situation. Pls advise me.
