Land grabbing is a common problem in India. After buying a plt, get a boundry wall around it and construct a room. Take water and electricity connection in your name. If you pay water tax and electricity bills for 12 months, Officially you are declared as having possession of the land and residing in it. No one can illegally claim it to be his.We already know that If a person has a proof of residence even in a rented room and he is not the owner, then also legally he can not be forced to move out of that property by the property owner. He can be forced to move out only if he has a rent agreement with the owner. This is the reason why rent agreements are made for 11 months only.
