No please.Both parties need to meet and both need to be basically secure both are genuineparties. secondly how you are sure you are signing with the right owner. besides both of you need to sign before registration authorities in person as registrar office needs to take snaps of both of you at the time of signing the documents. Inadition, you need to deduct TDS of 20% or 30% of the sale declared value and that should be remitted by you as a buyer to the Income tax against sellers Pan number, as that is mandatory obligation. Else income tax may punce on you as tax wants moneys now due to high govt deficit. if you fail you will have to pay that TDS yourself. understand the obligations then you have to take your own decisions.
firther buying the property you need to get encumberance free certificate from relevant tehsildar office or registration ffice per the state law concerned and should see wheter the man claiming is te genuine owner and all that. Onus is on you ..
buying and selling of properties is juct on a fun but very high responsibilities showed on both of you.
If the seller buys a [roperty within the time limit prescribed under capital gains then he can file his ROI in the relevant AY and claim refund against TDS YOU paid from the sellers moneys if not then seller gets credit of having paid capital gains tax.. regards... dr g.balakrishnan advocate (OS) Bombay high court
