My grandfather had a self-earned property of 24 acres in Krishna District, Andhra Pradesh. Almost twenty two years ago, our family had an understanding that my grandfather gets 6 acres, my father's brother gets 8 acres and my father gets 8 acres. The remaining 5 acres was to be sold to pay off the family debts. However, my father took that 5 acres on condition that he will pay the debts by himself and he paid them off. In 2009, my grandfather passed away without making any will. just six months after my grandfather's demise, we sold his 6 acres plus my uncle's eight acres (for his daughter's marriage). As our share, we got the money for grandfather's 3 acres. In the remaining 10 acres, my father and uncle have equal right on five acres each. So, as per the previous understanding within our family that my father should get extra five acres (for paying the joint family debt), my uncle gave his 5 acres to my father through a registered release deed, to save on stamp duty. During the registration, his only daughter, i.e, my sister, did not sign though she is unmarried and a major at that time. She acted only as a witness and gave her witness signature.
Now, six years after all this, my father wants to sell a part of our ten acres. My father is afraid that my sister may claim right on 2.5 acres of the 10 acres. So, he is willing to sell only acre 7.5 or less than that. The 24 acres that my grandfather originally owned is what he purchased from another party. It is not inherited by him from his parents. So, as the previous sale happened six years ago, will my sister win if she goes to the court of law or will the court accept the case, atleast? How genuine is our document? And can we sell more than 7.5 acres or the whole 10 acre bit?
