In a landmark judgment that is expected to send a large number of property owners into a tizzy, the Supreme Court held that the GPA method of immovable property sales is not a valid form of transfer of property.
A three-judge bench presided over by Justice R. V. Raveendran said that property can be lawfully transferred only through registered sale deeds.
"A power of attorney is not an instrument of transfer in regard to any right, title or interest in an immovable property," the bench said, after interpreting various provisions of the law concerning property sales. However, the bench said the judgment will not affect "genuine transactions" under the GPA.
"Nothing prevents affected parties from getting registered deeds of conveyance to complete their title. The said transactions may also be used to obtain specific performance or to defend possession under section 53A of TP (Transfer of Property) Act," the court said.
In order to ensure that GPA continues to serve its purpose, the court said its judgment will not 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 proper verification of ownership was possible only if all property were transferred through registered sale deeds.
