My partner has received legal advice, has paid his solicitor in full and is now in possession of all of his legal files. My partner is no longer represented. There is voluminous information on the Internet about the confidential requirements of a lawyer to the client during and after representation. However, I want to understand if the privilege works in reverse. The representation has ceased, and my partner would like to share these files with some people associated with parties my partner was adverse to. Under Australian Law, does he have the right to share the files, which contain direct communications from the adverse parties to my partner's lawyer, as well as statements from my partner about third parties who had a significant impact on the adversarial situation?
