Is there any law in india about distribution of father's property between daughters?

My father have lots of property in his name which include a huge building with two popular showrooms, a residential building and many lands. 90% of them he inherited from my grandfather. My father has two married daughters. Both me and my sister has one son each. Now my father has decided to give major part of his property to my sister's son and very small part to my son. So i feel cheated. Is there any law in india by which i can prevent this? Please help.
