Ancestral property registered on brother's name sister claiming share.

My grandfather registered the ancestral property on my father's and uncle's name and now my father's 3 sisters are claiming their share. My father is offering monetary settlement of 10 lakhs to each sister but they want the land. Sisters also filed a case against my grandfather, father and uncle. What are the possible solutions on this problem...??? Sisters have gone to the court so there's no chance of family settlement. Please help.
