Does this privilege apply to all communications with my lawyer? 

No, the legal privilege does not apply to all communications between a client and lawyer. There are several instances where the privilege would not extend to a communication between a client and his or her attorney. As stated above, the communication must be confidential. This means that the communication occurs solely between a client and his or her attorney unless an exception to that rule applies. If it is not confidential, then the privilege is waived. 

Additionally, there are attorney-client privilege exceptions under the Model Rules of Professional Conduct. An attorney is obligated to follow these ethical rules. One exception provides that communications from clients seeking legal advice to further or plan a crime or fraud are not privileged. Another exception exists when litigation arises disputing a deceased client’s estate. Under this exception, privilege may be waived permitting the attorney to testify as to the nature of the deceased client’s wishes. Other exceptions permit attorneys to disclose information to prevent reasonably certain death or substantial bodily harm as well as to prevent reasonably certain substantial financial or property injury to another.
