A restriction is an entry in the register regulating the circumstances in which a disposition of a registered estate or charge may be the subject of an entry in the register.
A restriction may, in particular—
prohibit the making of an entry in respect of any disposition, or a disposition of a kind specified in the restriction;
prohibit the making of an entry—
indefinitely,
for a period specified in the restriction, or
until the occurrence of an event so specified.
Without prejudice to the generality of subsection (2)(b)(iii), the events which may be specified include—
the giving of notice,
the obtaining of consent, and
the making of an order by the court or registrar.
The entry of a restriction is to be made in relation to the registered estate or charge to which it relates.
