Communications between a client and a lawyer for the purpose of seeking or providing legal advice are generally confidential and neither the client nor the lawyer can be compelled to disclose them. The protection that applies to such communications is called the "attorney-client privilege." The rationale behind the attorney-client privilege is to ensure that clients are able to tell their lawyers all of the facts relevant to the advice the client seeks, no matter how embarrassing or damaging those facts might be, to ensure that the client is able to obtain the best possible legal advice and to enable the lawyer to provide advice that is tailored to the client's specific situation.
In business litigation, the question of whether a party's spouse is fair game for a deposition often comes up. Sometimes, the question arises simply because a lawyer wants to demonstrate the willingness to "take the gloves off." Other times the issue arises because the spouse may be one of the only people likely to have knowledge of facts that could be central to the case. Regardless of the reason, Massachusetts lawyers should be aware of the applicable rules and the distinction between the spousal privilege and the spousal disqualification, which are set forth at M.G.L. c. 233 sec. 20(a) and (b).
