i have a piece of land in Himachal recorded in documents as nazayaz kabza by my nana ji since 1960. My nana ji passed away. we have a house and 3 shops on the said plot. since last 20 years my father has given 3 shops on rent to 3 local people. Now my father has passed away. I am afraid that those people will try to grab my property. How can I save it.
