The attorney-client privilege applies to communications “to whom disclosure is reasonably necessary for the transmission of the information or the accomplishment of the purpose for which the lawyer is consulted.” Cal. Evid. Code § 952. This includes communications to an expert consultant.
There are two major exceptions to the lawyer-client privilege under the California Evidence Code, as discussed below. 2.1. Crime or fraud. 2.2. Preventing death or substantial physical harm.
The attorney-client privilege does not apply to every communication with an attorney. For the privilege to exist, the communication must be to, from, or with an attorney, and intended to be confidential. In addition, the communication must be for the purpose of requesting or receiving legal advice.
This privilege is codified in California law via Evidence Code 954, which gives your attorney the right to refuse to divulge the contents of your conversation, gives you the right to require confidentiality from your attorney, and with few exceptions, makes any breach of that confidence inadmissible in court.
Start by including the words "privileged," "confidential," or "attorney-client communication" in your email subject line. Make sure the body of your email is clear, specific, and only discusses legal issues. Always ask your attorney before sharing information with others, including the contents of your emails.
Once a contract or retainer agreement has been signed between both parties, there's no question that privilege applies. Nonetheless, it generally starts before a contract is officially signed, even if you ultimately do not hire the attorney you had a consultation with.
