MAJORITY OPINION
ADELE HEDGES, Chief Justice.In this original proceeding, relators, Michael Hicks and Jerry Fazio, seek a writ of mandamus ordering the respondent, Judge Dan R. Beck, to vacate his order of June 18, 20071, granting a motion to compel discovery filed by the real parties in interest, Catherine Taylor, individually and as next friend of Charles D. Taylor, and William Heitkamp, Standing Trustee of the United States Bankruptcy Court. Concluding that the discovery is protected by the attorney-client and work product privileges, we conditionally grant the writ.
I. FACTUAL AND PROCEDURAL BACKGROUND
A. The Taylor Suit
Charles Taylor suffered an injury while on the job. His employer, relator Michael Hicks, was a non-subscriber under the Texas Workers’ Compensation Act, and Clarendon Insurance Group, Inc. was Hicks’s liability insurer. In 1999, Taylor filed a personal injury suit against Hicks and others regarding Taylor’s injuries (the “Taylor suit”). Clarendon assigned relator Jerry Fazio as defense counsel. In 2002, a jury returned a verdict of $20,000,000 in the Taylor suit.
*792While the Taylor suit was pending, Hicks and his wife filed for bankruptcy protection under Chapter 13 of the United States Bankruptcy Code. See 11 U.S.C. § 1301, et seq. In the bankruptcy proceeding, Hicks assigned to William Heit-kamp, as the Chapter 13 trustee, all claims, rights, and causes of action, “including but not limited to ... breach of any duty ... claims of negligence, negligent misrepresentation, fraud, ... insurance bad faith, fiduciary bad faith, fiduciary duty violation of any kind held or to be held against any liable person or entity whether perpetrated upon, resulting to, or incurred by Michael Porter Hicks, Sr., and/or [his wife and two other companies and their agents], for losses as well as any and all liabilities related in any way or by any legal or factual circumstance or source to that certain personal injury of Charles Taylor ... arising from or related to the damages suffered or claims made [in the Taylor suit],...”
In an agreed order signed by the Hicks-es and the bankruptcy judge, the bankruptcy court ordered that the bankruptcy plan contain the above assignment language, as well as the following language regarding cooperation by the Hickses:
The Chapter 13 Debtors, Michael Porter Hicks, Sr. and Carolyn Sue Hicks, agree and shall pursuant to this order timely cooperate with the Trustee or any agent or assignee of the Trustee for the Trustee or his assignee to execute instruments so that the Trustee or his assign-ee is able to receive and be provided information, testimony, documentation, and such rights as may exist for establishing liability and determining damages for the claims assigned, the proof of liability and any damages as well as the basis for legal recovery, legal documentation and evidentiary proof necessary for obtaining legal recovery of money whether by preparation of a documented claim, mediation, private arbitration, settlement or a trial. Further, Michael Porter Hicks, Sr., LMS Rentals, Inc., American Fabritech, Inc. together with Carolyn Sue Hicks further irrevocably and absolutely make such assignment of claims and rights to the Chapter 13 Trustee, William Heitkamp for the Trustee or his assignee to receive all documentation, information and testimony from Michael Porter Hicks, Sr., individually and/or as the agent or officer of LMS Rentals, Inc. and American Fabri-tech, Inc. Failure to cooperate to provide information, execute instruments of assignment, designation or in discovery for documentation, evidence or rights shall be grounds for objection to a final Chapter 13 or Chapter 7 discharge and the failure to obey this Order.
Several years later, on August 5, 2005, Fazio received a letter from an attorney representing Taylor and Heitkamp along with an “Authorization for Release of Information” signed by Hicks. The attorney requested that Fazio provide a complete copy of the file relating to the Taylor suit. The authorization, signed by Hicks on August 4, 2005, covered any documents or materials “comprising any aspect of the files or client information kept regarding” the Taylor suit and included the following language: “I specifically waive any attorney-client privilege which may exist with regard to any aspect of this authorization.” Fazio responded on August 8, attaching a revocation by Hicks of the authorization that he had signed just a few days earlier. In his revocation of the authorization, Hicks stated that he did not wish to waive his attorney-client privilege.
B. The Underlying Suit
Subsequently, Clarendon filed the underlying interpleader action seeking to tender the remaining insurance policy limits into the registry of the court. In addi*793tion to answering the suit, Taylor and He-itkamp filed counterclaims and cross-claims, asserting fraud and breach-of-contract claims against Clarendon and Hicks. Taylor and Heitkamp also asserted negligent-misrepresentation claims against Hicks, and they alleged that Clarendon, Hicks, and Fazio conspired to defraud Taylor and Heitkamp.
Hicks and Fazio propounded discovery requests, and Taylor and Heitkamp filed a motion for protective order in opposition to these requests, which the trial court heard on June 20, 2006. During the June 20 hearing, Taylor’s and Heitkamp’s counsel asserted that Hicks agreed to the release of the file in the Taylor suit in the bankruptcy order, and counsel made an oral motion for the trial court to order the file produced to Taylor and Heitkamp. Hicks and Fazio’s counsel objected that (1) the only motion Taylor and Heitkamp had filed was their motion for protective order against Hicks and Fazio’s discovery requests, (2) Taylor and Heitkamp had not filed a motion seeking to compel production of Fazio’s litigation file, nor had they requested that this file be produced in discovery. Taylor’s and Heitkamp’s counsel later made an oral motion for an order that Hicks sign a release authorizing Fazio to produce the litigation file.
The trial court did not make any ruling at the June 20, 2006, hearing but took the matter under advisement pending the filing of additional briefing. In a subsequent docket-sheet entry, the trial court made a notation indicating that Hicks was to execute an authorization for release of information and Fazio was to “produce entire file from the Taylor lawsuit.” Hicks and Fazio filed a mandamus petition in this court challenging this purported ruling by the trial court, but on September 8, 2006, this court denied the petition because there was no written order signed by the trial court.
Subsequently, Taylor and Heitkamp served a request for production on Hicks and Fazio seeking the litigation file from the Taylor suit. In response, Hicks and Fazio asserted only the attorney-client and work-product privileges. Taylor and Heit-kamp filed a written motion to compel, requesting that the trial court sign a written order compelling the production of the litigation documents from the Taylor suit that were requested by oral motion at the June 20, 2006 hearing and then by written discovery request. On June 18, 2007, the trial court signed an order compelling Hicks and Fazio to produce the requested discovery. Hicks and Fazio filed this original proceeding claiming the trial court abused its discretion in this order by (1) compelling production of Fazio’s litigation file, (2) compelling Hicks to sign an authorization to release privileged information that would waive his attorney-client privilege, and (3) granting Taylor’s and Heit-kamp’s motion for protective order.
II. ANALYSIS
In them first issue, relators contend the trial court abused its discretion in compelling disclosure of Fazio’s litigation file because the file is protected by the attorney-client and work product privileges. Taylor and Heitkamp concede that Fazio’s “core” work product is protected, and they have waived discovery of core work product. Taylor and Heitkamp claim, however, that Hicks waived the attorney-client privilege (1) through the assignment of rights in the bankruptcy order, and (2) through the authorization for release of information and documents addressed to Clarendon. At issue in this case is whether Judge Beck’s order requiring Hicks to produce Fazio’s litigation file would require disclosure of matters that are protected by the attorney-client privilege. If so, the trial court’s order would be a clear abuse of discretion for which writ of mandamus may issue. *794See West v. Solita, 563 S.W.2d 240, 244 (Tex.1978).
A. Intentional Waiver in the Bankruptcy Order
The attorney-client privilege is governed by Texas Rule of Evidence 503. Under this rule, 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.” Tex.R. Evid. 503(b)(1). The privilege covers not only direct communications between lawyer and client but also communications involving the client’s representatives and the lawyer’s representatives, so long as they were made for the purpose of facilitating legal services to the client. Tex.R. Evid. 503(b)(1)(A), (D).
The attorney-client privilege facilitates free and open communication between attorney and client and assures that the communication will remain confidential to promote effective legal services. See Republic Ins. Co. v. Davis, 856 S.W.2d 158, 160 (Tex.1993); Tex.R. Evid. 503. “Our rules recognize that our system of justice relies on a client’s privilege to speak frankly and candidly with his or her attorney.” Duncan v. Bd. of Disciplinary Appeals, 898 S.W.2d 759, 762 (Tex.1995). The privilege may be waived through voluntary disclosure or consent to disclosure under Texas Rule of Evidence 511.
Taylor and Heitkamp argue that there is no attorney-client privilege to protect confidential matter arising out of Fa-zio’s representation of Hicks because Hicks waived the privilege when he assigned his claims to Heitkamp in the bankruptcy order. An assignment of rights and claims does not automatically include a waiver of attorney-client privilege unless specifically stated in the language of the assignment. In re Cooper, 47 S.W.3d 206, 209 (Tex.App.-Beaumont 2001, orig. proceeding). In Cooper, the court of appeals addressed the status of privileged documents in a litigation file following assignment of a Stowers2 claim, and held that the privilege is not abrogated by the assignment. Id. The defendant Cooper had given the plaintiff a written assignment of his Stowers action, omitting any language that could be construed as an affirmative waiver of Cooper’s attorney-client privilege. Id. at 208. The trial court held that Cooper’s assignment of his claim was tantamount to a voluntary waiver of privilege. Id. at 208-09. The court of appeals rejected the proposition that assignment of a claim operates as a waiver of privilege associated with the underlying litigation. Id. at 209. Looking to the purpose behind the attorney-client privilege and the specific language of the assignment, the court concluded:
[T]he assignment’s language does not provide for Cooper to waive or assign any right he had to assert his attorney-client privilege. It does not provide for him to voluntarily disclose or consent to disclosure of any significant part of the matters protected by his attorney-client privilege. Nor does it even provide for Cooper to cooperate as to matters giving rise to his claims against his insurers.
Id.
In this case, the language of the bankruptcy order provides neither for Hicks to assign his right to waive the attorney-client privilege, nor for him to voluntarily disclose or consent to disclosure of any significant part of the matters protected by the attorney-client privilege. The only factual distinction between this *795case and Cooper is that the bankruptcy order contained language providing for Hicks to cooperate with regard to obtaining documentation to support his assigned claims. However, cooperation language alone is not sufficient to waive the attorney-client privilege.
Waiver is the intentional relinquishment of a known right made expressly or indicated by conduct that is inconsistent with an intent to claim the right. United States Fid. & Guar. Co. v. Bimco Iron & Metal Corp., 464 S.W.2d 353, 357 (Tex.1971). In this case, the language of the assignment in the bankruptcy order does not provide for Hicks to waive or assign any right he had to assert his attorney-client privilege.
Taylor and Heitkamp cite this court’s opinion in In re General Agents Ins. Co. of America, Inc., 224 S.W.3d 806 (Tex.App.Houston [14th Dist.] 2007, orig. proceeding), as support for the proposition that an assignment of rights and claims can include an assignment of the right to waive the attorney-client privilege. In that case, the party seeking discovery based its claim to privileged materials on an assignment of claims, alleging that the party that assigned its rights waived its right to assert any privileges by virtue of the assignment. Id. at 812. Before the trial court ruled on that contention, the parties filed a second assignment of rights, which specifically included assignment of “attorney/client communication privileges.” Id. at 813. In a, this court stated that the parties “thought the first assignment was sufficient to transfer the right to waive the privileges in question. Thus, the second assignment is more in the way of a clarification than a completely new agreement.” Id. at 814, n. 1. This court did not hold that the first assignment was sufficient to transfer the right to waive the attorney-client privilege, but merely recognized that the parties operated under that understanding.
In this case, the assignment language in the bankruptcy order does not specifically waive the attorney-client privilege. Further, the “cooperation” language does not impliedly waive the attorney-client privilege, especially in light of Hicks’s intent not to waive the privilege. Therefore, by assigning his rights and claims to the bankruptcy trustee, without specific language addressing the attorney-client privilege, Hicks did not assign the right to waive the attorney-client privilege. See Cooper, 47 S.W.3d at 209.
B. Implied Waiver in the Release to Clarendon
Taylor and Heitkamp further contend that Hicks waived the right to assert the attorney-client privilege by executing an authorization for the release of information and documents to Clarendon. On October 6, 2006, Hicks signed a release containing the following language:
TO: Clarendon Insurance Group, Inc., their agents, successors, and assigns.
RE: Coverage of and documents and communications concerning Michael Hicks and Taylor v. Hicks, Cause No. 97V-100 in the 155th Judicial District, State of Texas
You are hereby fully authorized and requested to permit the examination of, and copying or reproduction, in any manner, whether mechanical, photographic, or otherwise, by the Hershewe Law Firm, P.C., and their authorized agents, any and all portions of the following:
The full contents of any file(s) compiled concerning any insurance policies or coverage extended to me personally or to entities of which I was a principal and concerning the defense provided me during the above-referenced action, including communications with my counsel.
*796The authorization directed Clarendon to produce copies of the underwriting and claims files pertaining to Hicks’s insurance and defense including communications with Hicks’s counsel. Taylor and Heitkamp argue that the authorization “dispenses with the entire issue of ‘attorney-client’ privilege” because Hicks consented to disclosure of his communications with counsel to Clarendon. The attorney-client privilege may be waived through voluntary disclosure or consent to disclosure under Rule of Evidence 511. However, the record does not reflect that Hicks consented to disclosure of privileged material in Fazio’s litigation file. Taylor and Heitkamp emphasize the language in the release referring to “communications with my counsel.” Though the release includes communications with Hicks’s counsel, it is clear from context that this language refers to the insurance flies compiled by Clarendon, not Fazio’s litigation file. Further, the record contains another authorization directed to Fazio, but Hicks did not sign that authorization. Therefore, by executing the authorization for release of Clarendon’s file, Hicks did not waive attorney-client privilege with regard to Fazio’s litigation file. We sustain relators’ first issue.
In their second and third issues, Hicks and Fazio contend that the trial court clearly abused its discretion by, in its June 18, 2007 order, (1) compelling Hicks to sign an authorization to release privileged information that would waive his attorney-client and work-product privileges and (2) granting Taylor’s and Heitkamp’s motion for protective order. However, the trial court, in its written order, did not compel Hicks to sign an authorization or waiver, nor did the trial court grant a motion for protective order. Because the trial court did not grant the relief challenged in the second and third issues, we overrule these issues.
III. CONCLUSION
Relators timely asserted the work product and attorney-client privileges. The real parties in interest failed to show waiver of those privileges. The trial court therefore abused its discretion in ordering the privileged documents to be produced. We conditionally grant the petition for writ of mandamus and direct the trial court to vacate its order of June 18, 2007, compelling production of the litigation file. We are confident the trial judge will comply and the writ will issue only in the event he does not.
FROST, J., dissenting.
. The order reflects that it was signed June 18, 2006. The district clerk’s file stamp reflects that the order was filed June 18, 2007. A review of the record reveals that the order was actually signed June 18, 2007 and the date reflected in the trial judge’s signature line is a typographical error.
. See Stowers Furniture Co. v. Am. Indem. Co., 15 S.W.2d 544 (Tex. Comm’n App.1929) (recognizing the duty of an insurer to exercise ordinary care in the settlement of claims to protect its insureds against judgments in excess of policy limits).
