Yes, the stamp duty for PoA and registration fee depends upon the local laws. The Supreme Court's decision in Suraj Lamp & Industries (P) ... vs State Of Haryana & Anr does not rule out genuine transactions as in the instant case.
"19. We make it clear that our observations are not intended to in any way affect the validity of sale agreements and powers of attorney executed in genuine transactions. For example, a person may give a power of attorney to his spouse, son, daughter, brother, sister or a relative to manage his affairs or to execute a deed of conveyance. A person may enter into a development agreement with a land developer or builder for developing the land either by forming plots or by constructing apartment buildings and in that behalf execute an agreement of sale and grant a Power of Attorney empowering the developer to execute agreements of sale or conveyances in regard to individual plots of land or undivided shares in the land relating to apartments in favour of prospective purchasers. In several States, the execution of such development agreements and powers of attorney are already regulated by law and subjected to specific stamp duty. Our observations regarding `SA/GPA/WILL transactions' are not intended to apply to such bonafide/genuine transactions."
The Apex Court's ruling had been in the specific context of abuses of the power of attorney which had led to avoidance of stamp duty, capital gains tax etc. as delineated in the opening paras of the said judgment.:
"By an earlier order dated 15.5.2009 [reported in Suraj Lamp & Industries Pvt.Ltd. vs. State of Haryana & Anr. - 2009 (7) SCC 363], we had referred to the ill - effects of what is known as General Power of Attorney Sales (for short `GPA Sales') or Sale Agreement/General Power of Attorney/Will transfers (for short `SA/GPA/WILL' transfers). Both the descripttions are misnomers as there cannot be a sale by execution of a power of attorney nor can there be a transfer by execution of an agreement of sale and a power of attorney and will. As noticed in the earlier order, these kinds of transactions were evolved to avoid prohibitions/conditions regarding certain transfers, to avoid payment of stamp duty and registration charges on deeds of conveyance, to avoid payment of capital gains on transfers, to invest unaccounted money (`black money') and to avoid payment of `unearned increases' due to Development Authorities on transfer.
2. The modus operandi in such SA/GPA/WILL transactions is for the vendor or person claiming to be the owner to receive the agreed consideration, deliver possession of the property to the purchaser and execute the following documents or variations thereof:
(a) An Agreement of sale by the vendor in favour of the purchaser confirming the terms of sale, delivery of possession and payment of full consideration and undertaking to execute any document as and when required in future.
Or An agreement of sale agreeing to sell the property, with a separate affidavit confirming receipt of full price and delivery of possession and undertaking to execute sale deed whenever required.
(b) An Irrevocable General Power of Attorney by the vendor in favour of the purchaser or his nominee authorizing him to manage, deal with and dispose of the property without reference to the vendor.
Or A General Power of Attorney by the vendor in favour of the purchaser or his nominee authorizing the attorney holder to sell or transfer the property and a Special Power of Attorney to manage the property.
(c) A will bequeathing the property to the purchaser (as a safeguard against the consequences of death of the vendor before transfer is effected).
These transactions are not to be confused or equated with genuine transactions where the owner of a property grants a power of Attorney in favour of a family member or friend to manage or sell his property, as he is not able to manage the property or execute the sale, personally. These are transactions, where a purchaser pays the full price, but instead of getting a deed of conveyance gets a SA/GPA/WILL as a mode of transfer, either at the instance of the vendor or at his own instance."
