Information on ancestral property

 you the sibblings can file a suit for permanent injunction under specific relief act. with an interim application under order 39, rule 1&2 cpc with a prayer for tempoirary injunction directing your father not to alianate till the ancestral landed property is partitioned among the  successor-in-interests.

Dear Sir,

1. We would like to know is there any ways, that our father can sell the property without our concern when it is ancestral property? Is there any special Christian succession act where he can sell the property without our concern?

2. Today he has come up with new drama at home, saying he would sell the property, and devide the share into 6 parts, ie 3 for kids ( me and my 2 sibblings), 1 for my mother, 1 for himself and 1 for my grand mother. But three shares that is my mother's and grandmother's would be taken by him. We would like to know is there a seperate share for my mother and grand mother?
We are not greedy about the property, but the reason of asking this question is, we dont want him to sell the property to any third party, instead we want to hold it and delay as much as possible so that he would never be able to sell any piece of land in that property.

3. My grand mother was already given property share when the property was devided between my father and his sibblings, so is there any share to be given again to her? Moreover, he is too greedy, where he doesn't spend any money on her medical expense, in such case why should he get a property share? If we prove that he doesn't spend a penny on her medical expense, can we stop him in acquiring her share?

4. To be honest we do not want to share the property as this property would not be sold in anyways until he is alive, so is there any ways that we can hold by doing this. Because if it is devided, he would sell 50% of the property to some third party, and even after 2 years we are capable of buying it, he wont sell that to us, instead to others. What can be done about this?

Kindly please provide the answer for these

thanks and regards
