A recent agricultural land purchase has led to a dispute with the stamp registrar over alleged stamp duty shortages. The registrar claims the land falls within a factory's 200m radius, requiring commercial stamp duty. The buyer, unaware of this rule, is being asked for a 'service fee' by the officer to avoid penalties and a costly appeal process. Advice is sought on navigating this situation, including verifying the legality of the demand and seeking local legal counsel.
