A registered agreement is still an agreement
Registration and conveyance are two different things, and the word registered attaches to both, which is where the confusion comes from. Registering an agreement to sell puts it on the public register and preserves its effect for section 53A. It does not convert it into a transfer of ownership.
Section 54 draws the line in one sentence: a contract for sale does not, of itself, create any interest in or charge on such property. Nothing about registering the contract touches that sentence.
