OPINION
MOSELEY, Justice.Appellant Hugh F. Vanasek sued appel-lees Paul B. Underkofler, Jr. and the law firm of Goins, Underkofler, Crawford & Langdon (collectively “Underkofler”) for negligence, gross negligence, breach of contract, breach of warranty, and violations of the Texas Deceptive Trade Practices — Consumer Protection Act (DTPA). All of these causes of action arose out of Underkofler’s alleged actions or omissions while representing Vanasek in a previous lawsuit. The trial court granted Underko-fler’s motion for summary judgment and rendered a take-nothing judgment against Vanasek. In eleven points of error, Vana-sek contends the trial court erred in granting Underkofler’s motion for summary judgment. We affirm the summary judgment for Underkofler on Vanasek’s cause of action under the DTPA for breach of implied warranty. In all other respects, we reverse the trial court’s judgment and remand the cause to the trial court for further proceedings.
Background
A. Underlying Lawsuit
Vanasek owned an interest in a real estate development project. He sold his interest in the project to Albritton Development Company I, Ltd. (ADC), a limited partnership, which executed a note in favor of Vanasek. In 1987, the parties executed a new note in the amount of $666,400. ADC defaulted on the second note in 1990. In July 1990, Vanasek retained attorney Paul Underkofler to recover the balance owed on the note. Vanasek sued ADC and four of its eight partners, Robert Albritton, Ford Albritton, Jr., Ford Albritton, III, and James Wilson, III. These four partners had guaranteed the note. The defendants counterclaimed, alleging that Vanasek had fraudulently induced them to make the note and guaranty by misrepresenting that he had a major tenant for the property being developed.
A nonjury trial began on June 6, 1991. Vanasek testified and rested his case. Robert Albritton testified for the defense. During his testimony, however, the trial judge asked to see the parties’ attorneys in chambers. The trial was then recessed and continued to allow the parties to attempt to resolve the case through mediation. The mediation was ultimately unsuccessful.
During the June 6, 1991 proceedings, Vanasek began to lose confidence in Un-derkofler. Over the next several months, Vanasek became increasingly unhappy with Underkofler’s representation. As a result, Underkofler filed a motion to withdraw as Vanasek’s counsel, which was granted on May 22, 1992. Meanwhile in the fall of 1991, two ADC partners, Robert Albritton and Ford Albritton, Jr., filed for bankruptcy.
Vanasek hired new counsel and proceeded in his suit against ADC and the four *6partners guaranteeing the note. Vana-sek’s new lawyer also filed a separate lawsuit on the note against the remaining four partners in ADC who had not guaranteed the note and who were not defendants in the original suit.
On April 29, 1994, after an almost three-year recess, the trial of the promissory note lawsuit resumed. ADC, Robert Al-britton, and Ford Albritton, Jr. did not appear. After one witness testified on Va-nasek’s behalf, the trial was recessed again to give Robert Albritton the opportunity to appear and complete his testimony.
In September 1994, Vanasek and the six ADC partners who had not taken bankruptcy entered into a settlement agreement concerning the promissory note cases. Through the settlement Vanasek dismissed his claims against six of the ADC partners, but did not release or discharge any cause of action he had against ADC or the two partners who had filed for bankruptcy protection, Robert Albritton and Ford Albritton, Jr.
After the second recess, trial of the promissory note lawsuit again resumed on September 23, 1994. Vanasek appeared through counsel and was the only party to appear. On that date, the trial court entered judgment on the grounds of the settlement agreement and also entered judgment for Vanasek against the remaining defendants, ADC, Robert Albritton, and Ford Albritton, Jr.
B. Malpractice Suit
On April 6, 1994, almost two years after Underkofler withdrew as Vanasek’s counsel in the promissory note case, and just weeks before the trial of that case resumed after the first recess, Vanasek filed suit against Underkofler. In this, the “malpractice suit,” Vanasek alleged causes of action against Underkofler for negligence, gross negligence, breach of contract, breach of implied and express warranties, and DTPA violations. All of these causes of action arose out of Underkofler’s alleged actions or omissions while representing Vanasek in the promissory note lawsuit.
Vanasek’s discovery responses (and later his summary judgment response) listed numerous acts and omissions by Underko-fler allegedly constituting malpractice. These acts and omissions fall into two categories. First, Vanasek complained that Underkofler mishandled the suit on the note. For example, Vanasek alleged that Underkofler: (1) failed to list himself as an expert witness on attorney’s fees; (2) failed to proceed with discovery to obtain relevant documents; (3) failed during Va-nasek’s case-in-chief to offer evidence that Vanasek was the holder and owner of the note or evidence of the amount due thereunder; (4) failed to prepare for trial and to understand the facts surrounding the case; and (5) failed to join all ADC partners in the suit. Vanasek also asserted that Un-derkofler’s law firm should have recognized Underkofler’s malpractice and had another attorney from the firm continue to represent Vanasek.
Second, Vanasek alleged that Underko-fler agreed to recess the trial and submit the case to mediation without Vanasek’s knowledge or permission. Vanasek contended this delayed the underlying suit and cost him the opportunity to recover from Robert Albritton and Ford Albritton, Jr., the two ADC partners who filed Chapter 7 bankruptcy proceedings. Underko-fler moved for summary judgment in the malpractice suit, asserting he was entitled to judgment as a matter of law on ten separate grounds. The trial court granted the motion without specifying the ground or grounds relied upon for its ruling and rendered a take-nothing judgment for Un-derkofler. This appeal followed.
*7STANDARD OF REVIEW
The purpose of the summary judgment rule is not to provide either a trial by deposition or a trial by affidavit; rather, it provides a method of summarily terminating a ease when it clearly appears that only a question of law is involved and that no genuine issue of fact remains.1
Because the trial court granted summary judgment in this case on July 25, 1995, the “no evidence” summary judgment provisions of Texas Rule of Civil Procedure 166a(i) do not apply to this judgment.2 Thus to obtain a summary judgment, the movant has the burden of showing that there is no genuine issue of material fact and that he is entitled to judgment as a matter of law.3 In deciding whether there is a disputed material fact issue precluding summary judgment, we take evidence favorable to the nonmovant as true.4 We indulge every reasonable inference in favor of the nonmovant and resolve any doubts in its favor.5
Summary judgment for a defendant is proper when the summary judgment evidence negates an essential element of the plaintiffs cause of action as a matter of law or conclusively establishes all elements of an affirmative defense.6 Once the defendant produces sufficient evidence to establish the right to summary judgment, the burden shifts to the nonmovant to produce controverting evidence raising a fact issue as to the elements negated.7
We uphold a summary judgment on any ground that is supported by the evidence and pleadings.8 Because the order granting summary judgment does not specify the particular grounds on which the trial court relied, to prevail on appeal Vanasek must defeat each ground for summary judgment presented by Underkofler’s motion.9
Breach of Implied Warranty
Underkofler’s motion for summary judgment alleged that he was entitled to summary judgment because there is no cause of action under the DTPA for breach of implied warranty of professional services. In his tenth point of error, Vanasek contends that the trial court erred in granting summary judgment on his DTPA cause of action for breach of implied warranty.
The DTPA prohibits the breach of an express or implied warranty, but it does not create warranties.10 Actionable warranties under the DTPA must be recognized by the common law or created by statute.11 An implied warranty for services is a purely common-law creation.12 The Texas Supreme Court has held that *8Texas law does not recognize a cause of action for breach of an implied warranty of professional services.13 Thus we overrule Vanasek’s tenth point of error.
Speculative Damages
Underkofler’s motion for summary judgment alleged that he was entitled to summary judgment because Vanasek’s damages were too speculative for recovery as a matter of law. In his seventh point of error, Vanasek contends the trial court erred in granting summary judgment for Underkofler because the damages he suffered are not too speculative as a matter of law for recovery.
Damages are an element of each of Vanasek’s causes of action. To prevail on any of his causes of action against Underkofler, Vanasek must prove that he was damaged.14 While uncertainty as to the amount of damages is not fatal to recovery, lack of evidence or uncertainty as to the fact of damages is.15 Damages must be ascertainable in some manner other than by mere speculation or conjecture, and by reference to some fairly definite standard, established experience, or direct inference from known facts.16 Remote damages, or those damages that are purely conjectural, speculative, or contingent, are too uncertain to be ascertained and cannot be recovered.17
Additionally, a person alleging legal malpractice arising out of an attorney’s representation of him as plaintiff in an underlying case must prove the amount of damages he would have recovered and collected in the underlying case if it had been properly prosecuted.18 The principle behind this rule is akin to the requirement that a breach of duty must be the cause in fact of damages to justify recovery. Even if an attorney’s negligence prevented the entry of a judgment in his client’s favor, the client suffered no damage unless he could have collected some part of that judgment, used it to offset other debts owed to the judgment debtor, or otherwise benefitted from the judgment’s assignment. This principle applies as well to other causes of action, however named, against an attorney arising out of the attorney’s allegedly negligent representation in prior litigation.19
To properly obtain summary judgment on this ground, Underkofler had to negate conclusively the existence of Vana-sek’s alleged damages.20 In support of his *9motion, Underkofler relied on, among other things, portions of Vanasek’s deposition and the settlement agreement between Va-nasek and the six settling ADC partner’s, both of which were contained in the summary judgment evidence before the court. The settlement agreement reveals that Va-nasek settled his claims against the six ADC partners who did not take bankruptcy, including the claims he asserted against four of the partners in the underlying suit. In return, Vanasek received:
(1) $12,500 cash settlement from the six partners;
(2) the release from and dismissal of a $15,000,000 counterclaim asserted by two of the defendants in the promissory note case;
(3) the release of any liability Vanasek might have had on any other counterclaims, asserted and unasserted, of the six settling partners; and
(4) the assignment from the settling parties of a $10,000,000 claim against Robert Albritton’s bankruptcy estate.
The record also indicates that after the settlement, Vanasek pursued the underlying suit and obtained a judgment against ADC and the bankruptcy estates of Robert Albritton and Ford Albritton, Jr., jointly and severally, for $858,259.92; according to the record, Vanasek had collected approximately $12,000 of this judgment.
In his deposition, Vanasek described why he accepted the settlement with six of the ADC partners:
Had I continued with that case, I took a very, very good chance for getting hit for a $15 million judgment and being forced into bankruptcy. That’s the only reason I accepted that ludicrous $12,500....
Vanasek further agreed that the $15,000,000 counterclaim had been pending against him when he went to trial in June of 1991, and that the risks that a judgment might be rendered against him on the counterclaim were the same in 1991 as when he settled. He also testified that the promissory note lawsuit was reset for trial numerous times after Underkofler withdrew from the case, and that he asked for or agreed to a number of these resettings.
Thus the record before the trial court indicated that, for a factfinder to determine whether Vanasek suffered damages in fact as a result of the alleged malpractice (ie., whether the amount Vanasek would have collected in the promissory note case, absent any malpractice, exceeded the amount he actually collected), a finder of fact would have to determine the outcome of a number of contingencies, including:
(1) the outcome, absent any malpractice, of the $15,000,000 counterclaim asserted against Vanasek in the promissory note case and of the counterclaims of the other ADC partners that were not asserted in the promissory note case;
(2) whether the trial delay resulting from the alleged malpractice affected the existence or timing of bankruptcy filings of Robert Albritton and Ford Albritton, Jr. (the two ADC partners who filed for bankruptcy protection), and the nonfiling of bankruptcy cases by ADC and any or all of its other partners, and the effects of any such changes on the collectibility of any earlier judgment; and
(3) the ultimate amount and timing of any payments Vanasek may receive on the $10,000,000 claim against Robert Albrit-ton’s bankruptcy estate (which Vanasek received in the settlement with the other ADC partners), and on Vanasek’s $858,259.92 judgment against ADC and the bankruptcy estates of Robert Albritton and Ford Albritton, Jr., jointly and severally, in the promissory note case.
*10But while Underkofler may have presented evidence that Vanasek’s damages are speculative, we cannot conclude that the record conclusively negated the existence of Vanasek’s damages. Given the facts of this case it may be difficult for Vanasek to prove that he was damaged in fact as the result of Underkofler’s alleged malpractice. However, we decline to rule that there is no evidence that Vanasek could present at trial that would permit a finder of fact to resolve any contingencies concerning the existence of any damages in Vanasek’s favor. We sustain Vanasek’s seventh point of error.
One Satisfaction Rule
Underkofler’s motion for summary judgment alleged that he was entitled to summary judgment because allowing Vanasek to recover against him after settlement of the underlying case would violate the common law doctrine referred to as the one satisfaction rule. In his ninth point of error, Vanasek contends that the trial court erred in granting summary judgment because his recovery against Under-kofler does not violate the one satisfaction rule.
The one satisfaction rule prevents a plaintiff from recovering more than the amount required for full satisfaction of a single injury.21 Appellate courts have applied the one satisfaction rule when defendants commit the same acts as well as when defendants commit technically differing acts resulting in a single injury.22 When applicable, the rule reduces a non-settling party’s liability for damages by allowing a credit against any adverse judgment for the amount of any settlement entered into by a eotortfeasor.23 Underko-fler contends Vanasek had one injury — his claim on the note — and that as a matter of law he obtained one satisfaction for his injury when he settled the underlying case.
We conclude Underkofler has not shown that the one satisfaction rule entitles him to summary judgment in this case. Even if Vanasek suffered a single injury, and even if Underkofler is entitled to a credit against any of his tort liability by the amount of the settlement of Vana-sek’s underlying contract claims, we have already held that Underkofler has not conclusively established that Vanasek received full satisfaction for his injury by settling the underlying case. Absent such a determination, the application of the one satisfaction rule would not bar Vanasek’s recovery, but merely result in Underkofler receiving a credit against his liability in the amount of Vanasek’s settlement. We sustain Vanasek’s ninth point of error.
Causation
Underkofler’s motion for summary judgment alleged that he was entitled to summary judgment because, as a result of Vanasek’s settlement of the underlying case, Underkofler’s actions could not be a proximate or producing cause of Vanasek’s damages as a matter of law. Underkofler also alleged that he was entitled to summary judgment because Vanasek’s settlement of the underlying case is an intervening or superseding cause of his damages. Thus, Underkofler contended that he had conclusively negated the causation elements of Vanasek’s causes of action. In his first point of error, Vanasek contends that the trial court erred in granting sum*11mary judgment because genuine issues of material fact exist as to causation. In his second point of error, Vanasek contends that the trial court erred in granting summary judgment on grounds that the settlement was a superseding or intervening cause of damages.
A legal malpractice cause of action is a cause of action for negligence.24 Dividing a legal malpractice cause of action into separate actions for negligence, breach of contract, and other causes of action will not change the fact that the causes of action sound in negligence.25 A plaintiff seeking to recover for attorney malpractice must prove that the attorney’s breach of a duty owed to his or her client proximately caused the client’s injuries.26 Likewise, causation is an element of a DTPA claim;27 the plaintiff must prove that the DTPA violation was a “producing cause” of the plaintiff’s injuries.28 In most cases the issue of causation is a question of fact.29
Underkofler characterizes Vana-sek’s settlement of the underlying suit as “voluntary” and contends that Vanasek’s settlement, as a matter of law, severed any causative link between Underkofler’s alleged actions and any damages allegedly suffered by Vanasek. Vanasek presented evidence, however, that Underkofler’s alleged malpractice effectively forced Vana-sek to mitigate his damages by settling the underlying suit.30 Vanasek testified in his deposition that because of Underkofler’s handling of the suit, he was forced to settle his claims on the terms he did. Vanasek said that his “chances for a just trial and settlement were gone.” Under these circumstances, we cannot conclude as a matter of law that Underkofler’s alleged malpractice was not a producing or proximate cause of Vanasek’s alleged damages, or that the settlement was a superseding and intervening cause of Vanasek’s damages.
Further, even if the settlement was voluntary and a superseding and intervening cause of some of Vanasek’s damages, Vanasek did not settle with all defendants in the underlying suit. Three of the defendants in the underlying suit were not parties to the settlement agreement. Va-nasek proceeded to trial and obtained a judgment against them. Therefore, the settlement agreement does not as a matter of law break the chain of causation between Underkofler’s alleged malpractice and any damages to Vanasek’s ability to recover from the nonsettling defendants in the underlying suit.
Underkofler also argues that because Vanasek was represented by new counsel at the time of the settlement agreement and the conclusion of the trial, Underko-*12fler’s acts or omissions could not have proximately caused Vanasek’s damages. Underkofler asserts in his brief that, during the lengthy period of time between Underkofler’s withdrawal and the continuation of the trial and settlement with some of the defendants, Vanasek’s new counsel could have corrected any of Underkofler’s alleged mistakes. The summary judgment record, however, does not conclusively establish that Vanasek’s new attorney could have corrected any mistakes. The summary judgment evidence does not conclusively show that, during the protracted recess during trial, Vanasek’s new counsel could have amended his discovery responses, designated additional witnesses, or conducted additional discovery. Further, Va-nasek stated in his deposition that his new lawyer told him no further discovery was possible.
Neither does Underkofler’s argument address Vanasek’s allegations that Under-kofler’s agreement to recess the trial and submit to mediation itself damaged Vana-sek by delaying the resolution of the underlying lawsuit and reducing his ability to recover damages from Robert Albritton and Ford Albritton, Jr., the two ADC partners who filed Chapter 7 bankruptcy proceedings.
We conclude that the trial court erred in granting summary judgment for Underko-fler on grounds that he had conclusively negated the element of causation in Vana-sek’s claims. We sustain Vanasek’s first and second points of error.
Public Policy
Underkofler’s motion for summary judgment alleged that he was entitled to summary judgment because allowing Vanasek to pursue a malpractice suit against him after Vanasek entered into a settlement agreement violates the strong public policy which favors and encourages voluntary settlement of disputes. In his sixth point of error, Vanasek contends that the trial court erred in granting summary judgment on his legal malpractice cause of action because his pursuit of the malpractice cause of action does not violate public policy.
Underkofler relies on the Pennsylvania cause of Muhammad v. Strassburger, McKenna, Messer, Shilobod & Gutnick.31 In Muhammad, the plaintiff in the underlying suit apparently settled with the defendants and then decided the settlement was unsatisfactory. The plaintiff then sued the attorneys who obtained the settlement. Because of the strong public policy of encouraging settlements, the Pennsylvania Supreme Court did not allow the malpractice suit.32
However, the facts of this case are quite different from the facts in Muhammad. Vanasek did not enter into a settlement arranged by Underkofler and then later decide he wanted a bigger settlement. Instead, Vanasek claims he was effectively forced into the settlement because Underkofler’s alleged malpractice damaged his ability to recover his damages in the underlying case.33 Further, Vana-sek did not settle with all the defendants in the underlying suit; he proceeded to judgment against three of them. We conclude the public policy concerns at issue in Muhammad do not, as a matter of law, entitle Underkofler to summary judgment. Thus, we sustain Vanasek’s sixth point of error.
*13Limitations
Underkofler’s motion for summary judgment alleged that he was entitled to summary judgment because Vana-sek’s claims were barred by the statute of limitations. In his fourth point of error, Vanasek contends that the trial court erred in granting summary judgment on grounds that Vanasek’s causes of action are barred by the statute of limitations. We agree.
Each of Vanasek’s causes of action against Underkofler is governed by a two-year statute of limitations.34 Generally, a legal malpractice cause of action accrues when the client sustains a legal injury or, in eases governed by the discovery rule, when the client discovers or should have discovered the facts establishing the elements of a cause of action.35 Underkofler contends that, as a matter of law, Vanasek knew or should have known of the matters of which he complains more than two years before filing this lawsuit.
In Hughes v. Mahaney & Higgins, however, the Texas Supreme Court held that when an attorney commits malpractice while providing legal services in the prosecution or defense of a claim that results in litigation, the statute of limitations on the malpractice claims against the attorney is tolled until all appeals on the underlying claims are exhausted.36 Vanasek relies on Hughes to argue that the statute of limitations did not begin to run until September 23, 1994, the day the judgment in the underlying ease was signed. (No appeal was taken from that judgment.) Vanasek filed this malpractice suit on April 6, 1994, almost six months before judgment in the underlying suit. Underkofler, on the other hand, maintains that Hughes does not apply to the facts of this case.
One of the policy reasons behind the ruling in Hughes was that a plaintiff should not be forced to adopt contradictory positions in the underlying litigation and the malpractice action, thereby jeopardizing success in both.37 Underko-fler asserts that Vanasek’s allegations of malpractice are not inconsistent with any position he was taking in the underlying case and that therefore the Hughes rule does not apply. Underkofler ignores the second policy reason behind the holding in Hughes —tolling the statute of limitations promotes judicial economy and efficiency because the viability of the malpractice action depends on the outcome of the underlying action.38 If the claimant prevails on the underlying claims, his lawyer’s malpractice, if any, caused no damages.39 Further, we note that an attorney’s withdrawal before a final judgment does not prevent application of Hughes.40
We conclude the ruling in Hughes covers the facts of this case. Vanasek sued Underkofler claiming that Underkofler committed legal malpractice while provid*14ing legal services in the context of litigation. Under Hughes, the statute of limitations for these malpractice claims was tolled until there was a final judgment or other resolution in the underlying litigation.41 Accordingly, Vanasek’s legal malpractice claims were not barred by the statute of limitations.
Vanasek’s fourth point of error contends the trial court erred in granting summary judgment on limitations grounds as to all his causes of action, including his DTPA claims. We have already upheld the summary judgment as to Vanasek’s DTPA cause of action arising from breach of implied warranty. However, Vanasek’s DTPA allegations were not limited to that claim. He broadly alleged that Underko-fler’s “actions and omissions constitute a deceptive trade practice as that term is defined in the Texas Deceptive Trade Practices Act.” As to Vanasek’s DTPA claims other than for breach of implied warranty, Underkofler moved for summary judgment only on limitations grounds.
We conclude that the policy reasons behind Hughes also apply to a DTPA claim arising from an attorney’s acts or omissions related to underlying litigation. Just as a party should not be forced to adopt contradictory positions in a legal malpractice action against his counsel and in the underlying matter in which the malpractice allegedly occurred, neither should he be forced to adopt contradictory positions in a DTPA suit against his counsel and in the underlying matter. Tolling limitations on such a DTPA claim likewise promotes judicial economy and efficiency, as the viability of the DTPA action depends on the outcome of the underlying action. Thus, we hold the statute of limitations on Vanasek’s DTPA claims was tolled until there was a final judgment or other resolution in the underlying litigation. We sustain Vanasek’s fourth point of error as to his legal malpractice cause of action and his DTPA claims other than those based on breach of implied warranty.
Affirmative Defenses
Underkofler’s motion for summary judgment alleged that he was entitled to summary judgment on each of the following affirmative defenses to Vana-sek’s causes of action: waiver,42 estoppel,43 ratification,44 compromise and settlement,45 election of remedies,46 and Vana-*15sek’s failure to mitigate damages. Thus, Underkofler contended that he conclusively established all elements of these affirmative defenses.47 In his third point of error, Vanasek contends that the trial court erred in granting summary judgment on grounds that Vanasek waived his claims against Underkofler by settling the underlying lawsuit. In his fifth point of error, Vanasek contends that the trial court erred in granting summary judgment on grounds of waiver, estoppel, ratification, compromise and settlement, election of remedies, and failure to mitigate damages.
Underkofler relies on the same facts to establish each of the above-mentioned affirmative defenses. He contends the affirmative defenses bar Vanasek’s claims because Vanasek was aware of all the facts he claims constitute negligence by June 6,1991 (the first day of trial in the underlying suit), but made a knowing choice to settle the case instead of try it to completion. Again, Underkofler’s premise is faulty, however, because Vanasek maintains that Underkofler’s acts and omissions forced him into the subsequent settlement in mitigation of his damages caused by Underkofler’s malpractice. Further, Va-nasek did not settle all of the underlying suit; he tried the case to completion against three defendants. Therefore, Un-derkofler did not establish as a matter of law that Vanasek’s settlement of part of the underlying suit constituted waiver, es-toppel, ratification, compromise and settlement, election of remedies, or the failure to mitigate damages. To the extent it granted summary judgment for Underko-fler on grounds of these affirmative defenses, the trial court erred. We sustain Vanasek’s third and fifth points of error.
Conclusion
Because of our disposition of the preceding points of error, we need not consider Vanasek’s eighth and eleventh points of error. We affirm the summary judgment for Underkofler on Vanasek’s cause of action under the DTPA for breach of implied warranty. In all other respects, we reverse the trial court’s judgment and remand this cause to the trial court for further proceedings.
