Property Partition

My father had owned solely a land estate where we all lived. We are two brothers and three daughters.Before his death only,due to family tension I reconstructed made a seperate house on the same said land according to my father who had made his will then to distribute the land equally between two brothers but when the partition of land was about to take place ,my brother did not accept his share as he wanted more.Actually a small part of my share of land was in the other house he was living in.Since then ,we have been living seperately but My father never again brought the topic of partioning land between us due to my brother but hos will remanined the same throughout.Now he is no more and his will is still there but my brother doesn't agree to it.Actually my mother also owns some land which she wishes to give to me before her death but we don't want to attain ownership of my mother's land before the partition of my father's land in which we are living.Now my brother also wants equal share in mother's land so he will not even partition my father's land. What to do?
