The following provisions apply, in the circumstances set out, to disclosure of a communication or information covered by the attorney-client privilege or work-product protection.

(a) Disclosure made in a court or agency proceeding; scope of waiver. When the disclosure is made in a court or agency proceeding and waives the attorney-client privilege or work-product protection, the waiver extends to an undisclosed communication or information in any proceeding only if:

(1) The waiver is intentional;

(2) the disclosed and undisclosed communications or information concern the same subject matter; and

(3) they ought in fairness be considered together.

(b) Inadvertent disclosure. When made in a court or agency proceeding, the disclosure does not operate as a waiver in any proceeding if:

(1) The disclosure is inadvertent;

(2) the holder of the privilege or protection took reasonable steps to prevent disclosure; and

(3) the holder promptly took reasonable steps to rectify the error, including, if applicable, following subsection (b)(7)(B) of Kan. Stat. Ann. § 60-226, and amendments thereto.

(c) Disclosure made in a non-Kansas proceeding. When the disclosure is made in a non-Kansas proceeding and is not the subject of a court order concerning waiver, the disclosure does not operate as a waiver in a Kansas proceeding if the disclosure:

(1) Would not be a waiver under this section if it had been made in a Kansas proceeding; or

(2) is not a waiver under the law of the jurisdiction where the disclosure occurred.

(d) Controlling effect of a court order. A court may order that the privilege or protection is not waived by disclosure connected with the litigation pending before the court, in which event the disclosure is also not a waiver in any other proceeding.

(e) Controlling effect of a party agreement. An agreement on the effect of disclosure in a proceeding is binding only on the parties to the agreement, unless it is incorporated into a court order.

(f) Definitions. As used in this section:

(1) “Attorney-client privilege” means the protection that applicable law provides for confidential attorney-client communications.

(2) “Work-product protection” means the protection that applicable law provides for tangible material, or its intangible equivalent, prepared in anticipation of litigation or for trial.
