A father sold land in Bangalore via a sale agreement and irrevocable GPA, with payment promised via post-dated cheques. The buyer stopped payment on all cheques and is a known fraudster, having paid nothing. The seller is seeking advice on cancelling the agreement and GPA, especially concerning a lawyer's advice to pay a substantial stamp duty. Experts generally agree that since no consideration was paid, the agreement is void and can be cancelled via a legal notice, potentially avoiding court fees. However, the buyer's name appearing on the Encumbrance Certificate complicates matters, suggesting a court process might be necessary.
