This discussion clarifies that a GPA holder cannot execute a settlement deed to transfer property rights, as a GPA is not a title document. The holder's authority is limited to what's specified in the GPA. Any attempt to transfer property outside these terms, such as through a settlement deed to avoid taxes, is legally invalid. Subsequent transfers based on such invalid deeds will also be void. It's recommended to consult a local lawyer for advice on property transactions and tax implications.
