Priority between interests affecting a registered estate is not affected by the order of registration (section 28, the basic rule), but a registrable disposition for valuable consideration, once completed by registration, takes priority over any earlier interest whose priority is not protected at that time: an interest is protected if it is a registered charge, the subject of a notice, an overriding interest within Schedule 3, or appears from the register in the case of a lease (sections 29, 30). Inland Revenue charges are dealt with under section 31.
