My grand parents had no issued. My grand parents adopted my father (from her sister.). My grand father gifted a property to my grand mother.
My grand mother expired on 1958 and my grand father expired during 1959. During 1972 my father sold a portion of property to someone. During 1979 again he sold small portion ie., 10 x 16 size property. During 1991 again he sold a portion of the property. For all the above transactions none of has singed the sale agreements. We have filed the suit in the court saying it is joint family property. Please give me the high court citations also whereever necessary.
Please let me know the the rights of adopted son - natural sons property rights which inherited by mother.
