My grand mother registered a settlement deed(Dhana settlement in Tamil) for myself & my brother after my fathers death with a provision that it is not revocable at any stage. But due to some family problem she is now threatening us that she is going to cancel the settlement deed. But in the deed it is clearly mentioned that it is not revocable.
The property is owned by my grand mother only and it is not inherited. I heared that the settlement deed is revocable unilaterally by the donar without the knowledge of the claiments whether it is possible or not. Please give the appropriate answer. Thank you...
