Father Property

once the partition of the property has been done and confirmed by both the parties the demand of partition could not be raised by the parties.

if earlier partition admitted and proved then no remedy for further partition

how was the property divided after the death of father in 1969? By the mother or any way of instrument? If divided disproportionately some issue may arise as well .. Question lacks many facts.

once she got then never again as per law.

no

Don't be too greedy.

No chance. How many times do you want share.

if you still confused better to approach an advocate directly.

I think you have got your answer in your previous question...
