HI, I am currently living in USA and planning to purchase a small residential plot (from a broker) in Hyderabad, India outskirts. My dad saw the property and liked it. Now, I am planning to buy it. I just spoke to the broker (who owns an acre or more land and selling it in small pieces). According to him, he says that he shall courier me the registration forms to USA and asking me to sign it (along with my Aadhar xerox). Once I fill it up and send it back, he will get that registered in registration office. Is this legally valid ? Seller says no need for POA.
