• Rights on ancestral property

Dear Sir/Madam,
Our Grandfather had owned certain acres of agricultural land ( ancestral property )from his father. We have lost our grandparents years back. my father are 5 brothers ( 3 of them are no more ) & 2 sisters ( 1 is no more ). My father & his 3 brothers had their own jobs, except the elder one who took care of the whole land right from my grandparents time,but gave nothing from the income or the yield to any of his siblings, nor his parents when they were alive ( neither lived with them )but was enjoyed only by his family ( wife,1 son & 3 doughters including himself ).Years back when it was to be divided,he was adament not to part with the land,but agreed to give in the form of cash to all his 4 brothers.But that was also not done. now both the uncle & aunt are no more,son who is married but no issue is not in a possission to take care of himself is taken care only by his wife.  His father got him married against the wishes of his sisters. (they had their eyes on the property & hence never wanted their brother to be married.Neither they took care of him ). After my dad's brother death,the doughters have filed a case claiming the whole property. The case is on. My uncles have children. This is against we cousins,3 male members & 6 female,all married. None of us,neither our father,his brothers & we all children have ever had anything in cash or the yield from this ancestral property. The case is going on between my father ( who is 87 years old, who attends the court solely for all the hearing in favour of the whole family members.My uncle who is elder to my father is 89+ cannot attend the cases for his age factor. All his nephews are away working  at different places,who never attended. BUt this is for them all. I am the elder doughter ( we are only doughters )of my father. We have never interfered in his work, but he needs our support. Now we feel very bad,as he is also old & gets tired as his arguement for the property is for his kith & kin. I want to know each one of ours rights on the property, so we can help my father on his claim.As this is going on for few years now,pl give me the genuine sujjestion to fight for the same where it can  be decided soon according to the law. Looking forward for the reply at the earliest.
