dissenting.
I dissent. This case pits a lawyer’s duty to avoid harming a former client against the lawyer’s right to collect fees. In this case, Griggs & Harrison (G & H) ignored its former client’s confidential interests to collect its fees.
Judwin Properties, Inc., owns and manages apartment complexes in the Houston area. At four of these apartment complexes, it applied Chlordane, a termiticide, to the soil surface. Thousands of tenants have since complained that they were harmed by exposure to Chlordane. Judwin has been named as a defendant by over 700 plaintiffs in Chlordane exposure-related suits. To defend it in those suits, Judwin retained G & H.
During the course of G & H’s representation, Judwin paid attorney fees to G & H of over $928,000. Sometime during the litigation, a dispute arose between Judwin and its insurer, Reliance, about coverage and payment of attorney fees. Judwin ultimately filed suit against Reliance to obtain coverage and reimbursement of defense costs incurred in the Chlordane litigation, including fees owed to G & H.
In 1993, Judwin replaced G & H as its counsel in the Chlordane litigation. At that time, Judwin owed G & H about $56,000 in attorney fees. Before replacing G & H as its counsel, Judwin and G & H’s managing partner agreed that G & H would not attempt to recover the outstanding balance of its unpaid fees until after Judwin resolved its disputes with Reliance regarding coverage and responsibility for payment of G & H’s attorney fees.1 *871Despite this agreement, G & H made a demand on Judwin for the payment of the fees and, on the same day, filed suit against Jud-win. Attached to its petition, were the hourly fee statements. These statements detailed the work performed by G & H to defend Judwin in the Chlordane litigation. The fee statements contain individual entries that describe in detail the work performed by G & H from March 1992 and October 1992. Notably, the fee statements did not identify the time billed for each entry; the statements merely provide a total number of hours billed.2
The issue in this appeal is whether the disclosure of confidential information by G & H violated the duty or ordinary care and diligence G & H owed to Judwin.
Judwin complains on appeal that it was not necessary for G & H to publicly disclose the details of its work in a suit to collect fees; and, that the information disclosed was covered by the attorney-client privilege. In response, G & H attempts to justify disclosing confidential information under Texas Rule of Civil Procedure 185. G & H claims that, because it filed a suit on a sworn account, it was required to file the fee statements as an attachment to the petition. To counter that argument, Judwin replies that Rule 185 does not require a particularization of the account. Rule 185, “Suit on Account,” states in part:
No particularization or description of the nature of the component parts of the account or claim is necessary unless the trial court sustains special exceptions to the pleadings.
Tex.R. Civ. P. 185. Judwin is correct: Rule 185 does not justify G & H disclosing Jud-win’s confidential information in a suit on a sworn account.3
Next, G & H attempts to justify disclosing the confidential information under Texas Rule of Evidence 503(d)(3). G & H claims that, because the information was related to the fee dispute, G & H had no duty to withhold the information, relying on Rule 503(d)(3). Rule 503, “Lawyer-Client Privilege,” states in part:
(d) There is no privilege under this rule:

(3) Breach of Duty by a Lawyer or Client. As to a communication relevant to an issue of breach of duty by the lawyer to his client or by the client to his lawyer
Tex.R. Civ. Evid. 503(d)(3).
The majority agrees with G & H on this point and holds G & H could dislcose confidential attorney-client information because the information was related to the alleged breach. Because this is a summary judgment case, the majority necessarily holds that G & H proved, as a matter of law, it had no duty to Judwin not to disclose confidential attorney-client information. Another way of stating the holding is that, once a lawyer files suit for the collection of fees, the lawyer can disclose everything relating to the fee. Under this rationale, the lawyer can disclose all of the confidential information relating to the client’s business because the lawyer charged for all its work.
I disagree with the majority’s holding, its rationale, and its application in this case. I do not believe that Rule 503(d)(3) permits a lawyer to unnecessarily disclose confidential information in a fee dispute with a client. I agree that Rule 503(d)(3) permits a attorney who is in a fee dispute with his own client to reveal confidential information, but only so far as necessary to assert his claim. Cf. West v. Solito, 563 S.W.2d 240, 245 n. 3 (Tex.1978). That does not mean an attorney in a fee dispute can divulge confidential information protected by the attorney-client privilege that is not necessary to the resolution of the fee dispute. G & H should not have attached the detailed summary of its work *872that unnecessarily revealed confidential information protected by the attorney-client privilege.
The majority dismisses the effect of Disciplinary Rule 1.05 by saying that it does not create a cause of action or a presumption that a legal duty to a client has been breached. The majority’s statement is unfathomable. Judwin never claimed that Rule 1.05 created a cause of action. Judwin relies on Rule 1.05 as support for the policy that requires balancing the client’s and lawyer’s rights in disputes between them. Disciplinary Rule 1.05 concerns the need to maintain the confidentiality of client information, whether it is privileged or unprivileged.4
Under Rule 1.05, “a lawyer shall not knowingly” reveal or use confidential information except under limited circumstances. Tex. Disciplinary R. Prof. Conduct 1.05(b). When a dispute rises between a lawyer and his client, the lawyer may reveal confidential information only “[t]o the extent reasonably necessary to enforce a claim or establish a defense on behalf of the lawyer in a controversy between the lawyer and the client.” Tex. Disciplinary R. Prof. Conduct 1.05(c)(5); Potash Corp. v. Mandas, 942 S.W.2d 61, 66 (Tex.App.—Corpus Christi 1997, n.w.h.).
If the majority s opinion m this case were correct, no client could ever dispute an invoice. The majority’s opinion puts attorneys in the position to blackmail clients into paying their invoices with the threat of filing a suit on a sworn account with detailed summary of their work, just as G & H did in this suit, revealing confidential attorney-client information.
I would reverse.
. G & H disputes whether there was an agreement to refrain from filing suit. Because this is a summary judgment proceeding, we must assume that Judwin’s factual allegations are cor*871rect. Science Spectrum v. Martinez, 941 S.W.2d 910, 912 (Tex.1997).
. The fact that the fee statements did not identify the time billed for each entry highlights how unnecessary the detailed entries were to the collection suit.
. If G & H had felt it was necessary to divulge confidential attorney-client information in its suit, it could have filed the fee statements under Texas Rule of Civil Procedure 76a, which provides a mechanism for allowing documents to be filed in court under seal, without broad disclosure of the client's confidences.
. Rule 1.05, "Confidentiality of Information,” provides in part:
(a) "Confidential information" includes both “privileged information” and "unprivileged client information.” "Privileged information” refers to the information of a client protected by the lawyer-client privilege of Rule 503 of the Texas Rules of Evidence or of Rule 503 of the Texas Rules of Criminal Evidence or by the principles of attorney-client privilege governed by Rule 501 of the Federal Rules of Evidence for United States Courts and Magistrates. "Unprivileged client information” means all information relating to a client or furnished by the client, other than privileged information, acquired by the lawyer during the course of or by reason of the representation of the client.
(b) Except as permitted by paragraphs (c) and (d), or as required by paragraphs (e) and (0, a lawyer shall not knowingly:
(1) Reveal confidential information of a client or a former client to:

(ii) anyone else, other than the client, the’ client’s representatives, or the members, associates, or employees of the lawyer’s law firm.

(3) Use confidential information of a former client to the disadvantage of the former client after the representation is concluded unless the former client consents after consultation or the confidential information has become generally known.

(c) A lawyer may reveal confidential information:

(iv) prove the services rendered to a client, or the reasonable value thereof, or both, in an action against another person or organization responsible for the payment of the fee for services rendered to the client.
