General rule of privilege.

A client has a privilege to refuse to disclose and to prevent any other person from disclosing confidential communications made for the purpose of facilitating the rendition of professional legal services to the client: between the client or the client’s representative and the client’s lawyer or the lawyer’s representative; or between the client’s lawyer and the lawyer’s representative; or by the client or the client’s lawyer to a lawyer representing another in a matter of common interest; or between representatives of the client or between the client and a representative of the client; or between lawyers representing the client.

Privilege when client is a fiduciary.

When a lawyer represents a client who is serving as a personal representative, trustee, trust protector, directing party, guardian, conservator, guardian ad litem, attorney in fact for financial matters, health care agent, or other fiduciary, the lawyer’s client is the person who is acting as a fiduciary, and not anyone to whom the client owes fiduciary or other duties, and communication between the lawyer and such a client is protected from disclosure to the same extent as if the client was not acting as a fiduciary. The privilege may be claimed by the client, or otherwise as provided in sub. (3) , even against anyone to whom the client owes fiduciary or other duties.

The privilege may be claimed by the client, the client’s guardian or conservator, the personal representative of a deceased client, or the successor, trustee, or similar representative of a corporation, association, or other organization, whether or not in existence. The person who was the lawyer at the time of the communication may claim the privilege but only on behalf of the client. The lawyer’s authority to do so is presumed in the absence of evidence to the contrary.
