Power of attorney

There is no necessity to give power of attorney to the buyer, instead you can enter into a registered sale agreement.

The unregistered power of attorney deed is not valid as well as there are chances that the buyer may misuse the same.

"I want to sell my land of around 25 cents. The buyer agrees to pay 10 lcks advance but insisted a power of attorney in his name."

Is he is not willing to execute the conveyance deed? Or, is the POA in addition to the deed?

If buyer pays entire sale consideration of land then you can execute power of attorney in his favour else not.

If you give him POA, he can sell the land to any person on your behalf, but he can not get full rights over the property as the POA can be revoked at any time.

Prima faice the position is other-way-round where vendee is seeking sale deed whereas vendor is interested / insisting for PoA ? Isn't it?
