It's a case where your land belongs to a particular survey number of a village but you are in the physical possession, in some other (in most cases, neighboring) survey number. For a large part of the last 5 decades, transactions have taken place without the buyer paying much attention to the survey number. The problem gets much more complex when there are N number of survey numbers and N number of possessions, which cannot be solved by a simple one-one exchange.
As with every other case, the first step will be to identify the issue. Look up on Dharani, if your google location matches with the survey number, as mentioned in the cadastral maps. Apply for a govt. Survey and check if the survey report tallies with your understanding. When it comes to solving these issues, it can only be done through a thorough exercise of mutual co-ordination or through a court order.
