In 1973, Sub Judge ist class, Delhi gave probate on my grandfather's registered will dated 1967. A newer will, mentioning revising regd will dated 1969 was produced by one of my Aunts (without signatures of any witnesses), who did not contest at that time or do anything all these years. Now she wants her right as per the will dated 1969. Please guide what happens in such a scenario, is it not time barred now ? The floor at the time of court order had just one room & now that floor is fully constucted, rather 2 floors above also are constucted about 10-15 yrs back.
