Rule 502 - Attorney-Client Privilege and Work Product; Limitations on WaiverThe 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) Intentional disclosure; scope of a waiver. When a disclosure is made in a court proceeding and waives the attorney-client privilege or work-product protection, the waiver extends to an undisclosed communication or information 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 to be considered together. (b) Inadvertent disclosure. When made in a court proceeding, a disclosure does not operate as a waiver 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 Indiana Rule of Trial Procedure 26(B)(5)(b). (c) 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. (d) Controlling effect of a court order. If a court incorporates into a court order an agreement between or among parties on the effect of disclosure in a proceeding, a disclosure that, pursuant to the order, does not constitute a waiver in connection with the proceeding in which the order is entered is also not a waiver in any other court proceeding.
