Attorneys treat privileges as sacrosanct. We believe that everything a client tells us in private stays in our metaphorical vault, never to see the light of day under the attorney-client privilege. All good attorneys know that the client is the holder of this privilege, and even if an attorney wanted to tell-all, no attorney can waive this privilege without a client’s consent under California Evidence Code Section 912.

The same rule applies to doctors under Evidence Code Section 994. Relatedly, a spouse cannot testify as to anything their husband or wife told them in confidence while they were married if their spouse (or former spouse) objects under Evidence Code Section 980.
