ancestral property

I want to know about the right of daughter in the father’s property. Respected Sir, I need your valuable suggestions towards property rights of my mother and her sister. Their grandfather had few agriculture land and home property. He had settled those property among his four sons equally using a “kurra cettu” – local agreement during 1966. One of the sons is my maternal grand father. He had 3 sons and 2 daughters (including my mother). Recently came to know that he has executed a family settlement deed to the sons equally. My mother and her sister did not aware of it and they had registered the property in the registrar office in 2013.

Do we (my mother and my mother sister) have any rights to fight as the property came from  the grandfather considering as ancestor property?

My husband is a qualified doctor but he has not been practicing for seven years. I have two sons and one daughter. When my husband does not take care of us, can I claim my husband’s paternal property? My husband does not own any immovable property. He is a jobless person. My father-in-law is a class one officer and he has a huge property. My husband is the only son so he will get all self acquired and ancestral property after the death of my father in law. 

How the daughters get a share in the ancestral property? I am 34 years married daughter, live in Delhi. My ancestral property situates in UP Bagpat. We are 4 brothers & sister and my brother has died in a road accident, now we are three sisters only. As per the govt of India regulations the ancestral property should be divided between us equally. I would like to take my part as well. Please suggest. What is the process for this and how can I claim for this? Need to advise how to take my share from the ancestral property as a daughter.

Who will get the agricultural land after father’s death? Father holds one-acre agricultural land. He has a wife, three daughters and one son.
