The proprietor may request the registrar on Form TM25 for such alteration of his registered mark as is permitted under section 44; and the registrar may require such evidence by statutory declaration or otherwise as to the circumstances in which the application is made.

Where, upon the request of the proprietor, the registrar proposes to allow such alteration, he shall publish the mark as altered.

Any person claiming to be affected by the alteration may within three months of the date of publication of the alteration under paragraph (2) send a notice on Form TM7 to the registrar of opposition to the alteration and shall include a statement of the grounds of opposition; the registrar shall send a copy of the notice and the statement to the proprietor and thereafter the procedure in rule 13(2)-(8) shall apply to the proceedings as they apply to proceedings relating to opposition to an application for registration.
