my grandmother executed a will in 1982. she made 5 shedules of property for her 2daughters and 2 sons and 1 grandson. grandmother died on 1998. one part of my mother'shedule property was in the possession of her younger brother for 20 years. That shedule property,was sold by executing by sale deed in 2008,by younger brother's wife,to her husband and her son. when i took EC(nov 2015) ,it shows as non conveyence by executant (younger brother's wife),claimants are her husband and her son. IS this sale is valid or not? is the will is valid or not?(35 years old will)(one of the wittness signed in the will is alive) can i file the suit for declaration of my mother 's (one daughter) right and possession of property or suit for partition o r for setaside the sale of property? and can my mother make a will in my name regarding her mentioned shedule property on basis of will executed my grandmother in 1982. please advise.
