My Grandfather purchased a property/house in my Father's name in 195X through a Sale deed. At that time my father was 8 years old (a minor). In 1977 my grandfather executed a registered WILL giving part of that property to his daughters and grandsons etc. Even today, the property stands in my fathers name in the registration records. My father was a major when my grandfather executed the will.
My questions are.
Since the property was standing in my fathers name in 1977, does my grandfather had any right to execute the WILL?
Is that will any Valid?
Can my father today challenge that will?
Can my father gift the same property to me since it is in his name even today?
Thanks in advance
