Daughter share ancestral property

I have one scenarios like , my father have 4 children ( 3 Daughter and One Son) . Around 2007 my father created partition deed saying some quoted false reason of personal loan and other. He created the partition deed saying one site ( 30X 40 Site ) to each , means for daughters and Son , he registered to all from Self earned property and rest all taken to his names ( including ancestral and self earned property) . We have all signed the partitioned paper ( forcefully got it from us ) , now my question is : We have rights to claim share in my ancestral property through legal right ..? Please advice me on this Thanks
