No entry shall be retained in the register after the expiration of the initial period of registration except in pursuance of a renewal application made to the Registrar in accordance with this section.

Subject to subsection (3) below, the initial period of registration and the period for which an entry is to be retained in pursuance of a renewal application (“the renewal period”) shall be such period (not being less than three years) as may be prescribed beginning with the date on which the entry in question was made or, as the case may be, the date on which that entry would fall to be removed if the renewal application had not been made.

The person making an application for registration or a renewal application may in his application specify as the initial period of registration or, as the case may be, as the renewal period, a period shorter than that prescribed, being a period consisting of one or more complete years.

Where the Registrar notifies an applicant for registration that his application has been accepted the notification shall include a statement of the date when the initial period of registration will expire.

Any renewal application may be sent by post, and the Registrar shall acknowledge its receipt and notify the applicant in writing of the date until which the entry in question will be retained in the register in pursuance of the application.

Without prejudice to the foregoing provisions of this section, the Registrar may at any time remove an entry from the register at the request of the person to whom the entry relates.
