For the purpose of facilitating the service of notices and other documents, every solicitor who has in force, or has applied for, a practising certificate shall give notice to the Society of any change in his place or places of business before the expiration of 14 days from the date on which the change takes effect.

Any notice or other document required or authorised by or by virtue of this Act to be served on any person may be served on him by delivering it to him, by leaving it at his proper address or by sending it by post.

Any such notice or document may be served on a practising solicitor, without prejudice to any other method of service, by sending it in a registered letter addressed to him at any place specified as his place of business, or one of his places of business, in his latest application for a practising certificate or in any subsequent notice under subsection (1).
