Family dispute over land

How come sisters got the property?  If it is ancestral then one of the sisters cannot sell the property.

yes they got when there father expired.

not only she sold her right on joint owned  but also on the 1 where7/12 have only moms name

I have my grandfather's undivided land. I have four uncles. They all don't want to divide the land because they are wealthy and no need of house but we are getting problem because we don't have divided land on which we can build even a small house. When we ask them to divide the land they don't care and avoid us.

One of uncle has built a construction on that land which has covered 3/5th of total land. We don't have even land available for our share. Can you please advise how we can legally proceed for land dividation and removal of construction built on our share of land? +918378975977

Sir

Your sister who sold the Property had right on her Share alone. No body can sell the Property of others Share. It is not legally  bind. The other sisters and your mothers can ask for partition.

Your sister can sell only her legitimate share of property and any act done beyond that is an act of criminal breach of trust and cheating which is not binding on others and considered illegal and invalid by law.
