This document summarizes Section 43 of the Transfer of Property Act, known as the doctrine of feeding the grant. It establishes that if a person fraudulently or erroneously represents that they are authorized to transfer a property and professes to transfer it for consideration, then any interest they acquire in the property during the contract will pass to the transferee at their option. There are a few exceptions: the right of transferees in good faith for consideration without notice is not impaired, and the benefit only applies to transfers for value, not gifts. The section is based on principles of estoppel from common law and equity to fulfill promises when ability arises.
