Buying a Purbachal plot while living abroad
Short answer
You can buy a Purbachal plot from abroad if you appoint a trusted representative through a properly drafted legal authority, verify the plot by live video, pay only through traceable bank channels, and keep one clear point of contact who updates you in your own time zone.
Do I need to fly home?
Not always. A properly drafted power of attorney lets a trusted person act for you. Take legal advice on how to prepare it.
How do I see the plot?
Ask for a live video walk of the boundary and the access road, and compare it with the plan.
How should I pay?
Through bank channels with receipts, never in cash.
