Property document

Hi, I had bought a 30*50 plot in somahettyhalli village, Bangalore North. (khata number 36, assessment number 25). There are few survey numbers for which preliminary notification was issued by BDA for the formation of Shivaram karanth layout in 2008. However, the order for formation of layout was quashed by the high court in the year 2015 due to delay by BDA in issuing final notification. With all my life time savings, I bought a plot in 2016 in somahettyhalli, after the layout formation was quashed. Now, I am not sure if my plot belongs to the notified survey number. There are many such plot owners in this area. It also has few schools, factories and houses in the surrounding are of my plot who are in the fear of loosing land to BDA. Please let me know what steps I can take further in case my plot is acquired. Would I get any compensation if my plot is acquired. Is there anythin we can do as a group (all plot owners) to protect our land? Is there any solution for this. Please help! Thanks, Suma
