Our Grandfather had purchased some Revenue sites in and around Bangalore and registered all in the name of my Grandmother during the year 1950-1970. Grandfather expired 10 years ago. They have four sons. Now, my Grandmother has "Gift Deeded" some of the properties 3 months back to her other children ignoring the elder son.
My question is, can the elder son challenge these gift deeds and is he valid to claim on the same properties?
Kindly suggest. It is very urgent.
