Any communication made to or by an incorporated practice in the course of its acting as such for a client shall in any legal proceedings be privileged from disclosure in like manner as if the body had at all material times been a solicitor acting for the client.

Any enactment or instrument making special provision in relation to a solicitor or other legal representative as to the disclosure of information, or as to the production, seizure or removal of documents, with respect to which a claim to professional privilege could be maintained, shall, with any necessary modifications, have effect in relation to an incorporated practice as it has effect in relation to a solicitor.
