Generally, in a U.S.
Federal court, the applicable attorney-client communications remain privileged after the death of the client, unless a disclosure is necessary to help determine the intent of the client’s last will and testament, or unless a disclosure serves the client’s interest.
Otherwise, the attorney may reveal no more privileged information than if the client were alive.
The states follow the same general guidelines. There have been some exceptions, most significantly during criminal proceedings, where the court must balance the interests of privacy and justice.
