What not to tell an attorney?

What not to tell an attorney in Australia is limited, because attorney-client privilege protects confidential communications, so you can generally tell your attorney anything and they cannot disclose without your permission, except in rare circumstances. However, there are things you should not tell or should be careful about. You should not tell your attorney that you intend to commit a future crime or fraud, because lawyer has duty to prevent serious harm and may have to disclose to prevent crime. For example, if you tell lawyer you plan to lie under oath or fabricate evidence, they must not assist and may have to withdraw. You should not tell your lawyer lies, because if you lie to your own lawyer, they cannot give accurate advice and may inadvertently mislead court, which can harm your case and lead to perjury. You should not tell your lawyer information via email or phone that is not secure if case is sensitive, use secure communication. You should not tell your lawyer you do not want to know something, because wilful blindness does not protect you. In Australia, legal professional privilege is strong, but does not apply if communication is for purpose of committing crime or fraud, known as crime-fraud exception. So you can tell your attorney about past crimes you committed, they must keep confidential and defend you, you should be fully honest about past facts. What not to tell is future criminal plans or ask them to help lie. Also do not tell attorney to destroy evidence, as that is obstruction. So be honest about past, do not ask to commit future wrongdoing.
