OPINION
¶ 1 This case requires us to decide when a cause of action accrues for legal malpractice occurring in the course of criminal litigation. We granted review because the issue is one of first impression in Arizona and is of statewide importance. We have jurisdiction pursuant to Article 6, Section 5(3) of the Arizona Constitution, Arizona Rule of Civil Appellate Procedure 23, and Arizona Revised Statutes (“A.R.S.”) § 12-120.24 (2003).

¶ 2 James R. Glaze was convicted in superior court of one count of sexual abuse and was sentenced to a one-year term of probation. Eric A. Larsen represented Glaze in the trial proceedings. Larsen also represented Glaze on his direct appeal, in which the court of appeals affirmed the conviction. State v. Glaze, 2 CA-CR 96-0145 (Ariz.App.Jan. 14, 1997) (mem.deeision).
¶ 3 Glaze, no longer represented by Larsen, then filed a petition in the superior court
¶ 4 On remand, the superior court found that Larsen had been ineffective in failing to request the jury instruction and granted Glaze a new trial. Glaze then filed a motion to dismiss the charges with prejudice. The superior court granted the motion to dismiss on July 6,1999.
¶ 5 On December 14, 2000, Glaze filed suit against Larsen, alleging that Larsen’s negligence had caused the criminal conviction. The superior court granted Larsen’s motion to dismiss, holding that Glaze’s claim was barred by the two-year statute of limitations in A.R.S. § 12-542 (2003), which provides that negligence actions “shall be commenced and prosecuted within two years after the cause of action accrues.” The trial court found that the cause of action had accrued on September 30, 1998, the date the court of appeals held that Glaze had a colorable claim for ineffective assistance of counsel.

See Kiley v. Jennings, Strouss & Salmon,
¶ 10 The determination of when a cause of action accrues requires an analysis of the elements of the claim presented. For example, it has long been settled that an essential element of a claim for malicious prosecution is that the prosecution terminate in favor of the plaintiff.
See Overson v. Lynch,
¶ 11 No Arizona case addresses when a cause of action accrues when the allegation is that a lawyer’s malpractice has caused the plaintiffs criminal conviction. Our cases, however, have repeatedly addressed when a cause for legal malpractice in the civil context accrues. We first turn to an analysis of those cases.
A.
¶ 12 As with all negligence claims, a plaintiff asserting legal malpractice must prove the existence of a duty, breach of duty, that the defendant’s negligence was the actual and proximate cause of injury, and the “nature and extent” of damages.
Phillips v. Clancy,
V13 Given these elements of the tort claim, a legal malpractice claim accrues when “(1) the plaintiff knows or reasonably should know of the attorney’s negligent conduct; and (2) the plaintiffs damages are ascertainable, and not speculative or contingent.”
Ki-ley,
¶ 14 The
Amfac
decisions applied these general principles to a claim that an attorney’s negligence in failing to name a proper plaintiff resulted in the dismissal of a lawsuit.
See Amfac I,
¶ 15 This holding was directly tied to the basic elements of the legal malpractice tort. The defendant in
Amfac
asserted that the plaintiffs cause of action had accrued when the plaintiff knew or should have known of the defendant’s negligent conduct.
Id.
That argument, however, ignored “one of the essential elements of a claim for negligence — injury to the plaintiff.”
Amfac I,
B.
¶ 16 In addition to correlating the accrual of the cause of action for legal malpractice to the presence of the elements of the tort, the
Amfac
decisions recognized several practical difficulties inherent in legal malpractice actions arising out of alleged negligence in handling litigation. First, “[e]ven where an attorney’s performance in litigation is obviously poor, most clients would not be able to make an informed judgment whether the conduct constitutes malpractice” until “the litigation is terminated and the client’s rights are ‘fixed.’ ”
Amfac I,
¶ 17 The Amfac rule also serves important goals of judicial efficiency. If the cause of action for legal malpractice were to accrue at the time of the allegedly negligent conduct, malpractice plaintiffs might well be required to file suit while their underlying litigation was still pending. Moreover, plaintiffs would be required to argue in their malpractice suits that the underlying case would have had a different outcome in the absence of them attorney’s negligence. The trial of the malpractice claim would therefore involve the very evidence that had yet to be presented in the trial of the underlying matter. And even when the trial of the underlying matter has been completed before a malpractice claim is filed, the trial court in the malpractice action will be forced to go through the exercise of determining how a case would have come out in the absence of the alleged malpractice at the same time that the parties are awaiting an appellate decision that may well answer that very question or remand the case for a new trial.
¶ 18 These problems are avoided by the Amfac approach, which requires the final termination of the underlying litigation before the malpractice cause of action accrues. At least in some eases, this approach will make a malpractice suit unnecessary, either because the underlying litigation eventually is resolved in favor of the malpractice plaintiff, or because the appellate process has made plain that the result in the underlying litigation would have been the same even absent the attorney’s alleged malpractice. The Amfac rule thus not only prevents premature litigation, but at least potentially prevents the filing of wholly unnecessary malpractice lawsuits.

A.
¶ 19 Glaze’s claim in this litigation necessarily is that he would not have suf
¶20 But there is an important difference between civil and criminal procedure with respect to the alleged errors of counsel. In the civil context, a party generally cannot obtain post-judgment relief because of the inexcusable neglect of counsel.
See Panzino v. City of Phoenix,
¶ 21 Such post-conviction proceedings in the criminal case may well establish that any alleged negligence by counsel was not the cause of the conviction, either because the attorney did not depart from the applicable standard of care or because the conviction would have ensued in any event.
See Strickland v. Washington,
¶ 22 Other practical concerns also support a rule preventing accrual of criminal malpractice actions while the underlying case is still being litigated. If the criminal defendant were required to institute a civil malpractice suit while his case was still pending in the courts, counsel might well be disqualified from further handling of the criminal ease, or at the very least be discouraged from doing so. It is also quite likely that even if the attorney remains on the case after being made a party in the civil suit, he would be distracted from the job before him by defending against the civil negligence claims.
See Shaw,
¶ 23 Thus, we see no reason to depart from the principles announced in Amfac in the context of allegations of malpractice in a criminal proceeding. Just as the malpractice cause of action in the civil context does not accrue until all proceedings in the underlying civil case, including appeals, are terminated, a claim that an attorney’s malpractice resulted in the conviction of a criminal client does not accrue until the complete termination of the criminal proceedings. Those proceedings include not only the direct appeal, but also any proceedings involving petitions under Rule 32 and any retrials, appeals from judgments in retrials, or post-conviction proceedings following retrials. See Ariz. R.Crim. P. 32.3 (“[Rule 32 proceedings are] part of the original criminal action and not a separate action.”).
B.
¶24 The accrual of a cause of action for malpractice in the course of criminal representation depends not only on the fact that the underlying criminal proceedings have been terminated, but also on how they were terminated. Because an essential element of the malpractice claim is that the plaintiff would not have been convicted in the criminal action but for his attorney’s negligence, the malpractice suit is in essence a collateral attack on the conviction. Principles of finality and respect for judgments have led “most jurisdictions addressing the issue” to conclude that “a convicted defendant seeking damages for malpractice causing a conviction must have had that conviction set aside” as a prerequisite to obtaining damages in a malpractice action. Restatement (Third) of the Law Governing Lawyers § 53 cmt. d.
¶ 25 The decisions from other jurisdictions addressing this issue vary somewhat in their language.
See, e.g., Shaw,
¶26 While some cases suggest that the conviction must be reversed through a particular post-judgment proceeding, we believe such a rule unnecessary. Convictions can be
¶ 27 Rather, “any post-conviction relief suffices,”
Shaw,
C.
¶ 28 California, while adhering to the majority rule that “appellate or other postcon-viction relief [is] a predicate to recovery in a criminal malpractice action,”
Coscia,
¶ 29 Larsen urges us to adopt this “two-track” approach. He argues that requiring plaintiffs to file suit within two years after they know or should have known of the lawyer’s negligence will serve to prevent stale litigation and place defendants on notice of possible claims.
See Ritchie v. Grand Canyon Scenic Rides,
¶ 30 We decline that invitation. At the outset, it is worth noting that the “two-track” approach in
Coscia
arose at least in part from California’s particular statute of limitations, which required that the malpractice action be brought no later than four years from the date of the wrongful act or omission.
Coscia,
¶31 Unlike the California statute, A.R.S. § 12-542 has no arbitrary limit on the time in which legal malpractice claims can be brought. Rather, the only question is when the “cause of action accrues.” As noted above, the general rule is that a cause of action accrues when all of the elements of the cause are present and the plaintiff either knows or should have known of them. Because we hold that favorable termination of the criminal proceedings is an element of the cause of action for malpractice, it logically follows that the cause does not accrue until favorable termination occurs.
Cf. Owen,
¶ 32 Moreover, the “two-track” approach presents serious problems of judicial administration. It encourages the filing of malpractice suits that may be unnecessary, because the criminal defendant/malpractice plaintiff will often ultimately be unable to obtain a favorable termination in the criminal action. Although the civil suit may be stayed pending completion of the criminal proceedings, the stay does not avoid the conflict problems that will arise when a defendant in a criminal matter brings suit against his current counsel. And, because a “two-track” system implicitly assumes that the malpractice cause of action accrues within two years of the discovery of counsel’s negligence, malpractice suits will thus often be required to be filed while cases still are on direct appeal, thus maximizing the chances for conflict.
¶33 Nor do we believe that the rule we adopt today will result in the filing of stale claims or seriously impact the ability of counsel to defend legal malpractice trials. Although the criminal process may last longer in many cases than civil proceedings, appeals in complex civil cases may also last for years; yet
Amfac
holds that a malpractice claim, even one arising from actions or omissions early in the representation, does not accrue until all appeals are complete. As
Amfac I
noted, the dangers of delays are lessened when the alleged malpractice occurs during litigation, because generally “a record will have been made of the actions which form the substance of the later malpractice action” in “court pleadings or in hearing transcripts” in the underlying litigation.
¶ 34 Moreover, unlike the civil context, in which the attorney/defendant may never learn during the underlying proceedings that his client claims malpractice, criminal counsel will usually be made aware of such a claim before the criminal proceedings conclude. Such claims must usually be raised in a defendant’s first Rule 32 petition,
Spreitz,
IV.
¶ 35 For the reasons discussed above, we hold that a cause of action for legal malpractice that occurs during the course of criminal litigation does not accrue until proceedings in the criminal matter have been terminated favorably to the criminal defendant. In this case, the proceedings so terminated on July 6, 1999, when the superior court dismissed the criminal charges against Glaze with prejudice. Because the legal malpractice action was filed on December 14, 2000, it was commenced less than two years after the cause of action accrued, and thus was timely under A.R.S. § 12-542.
¶ 36 The opinion of the court of appeals is vacated, and this case is remanded to the superior court for further proceedings consistent with this opinion.
Notes
. In contrast, when a legal malpractice action arises in a non-litigation context, the cause of action accrues when the plaintiff knew or should have known that its attorneys had provided negligent legal advice, and that the attorneys' negligence was the direct cause of harm to the plaintiff, notwithstanding that the plaintiff's damages may not have been fully ascertainable at that time.
Commercial Union Ins. Co. v. Lewis and Roca,
. In a legal malpractice action, the plaintiff has the burden of demonstrating by a preponderance of the evidence that "but for the attorney's negligence, he would have been successful in the prosecution or defense of the original suit.”
Phillips,
. We are not confronted today with the issue of whether the determination in a post-conviction relief proceeding that ineffective assistance of counsel has been provided has a preclusive effect in a subsequent civil case alleging malpractice. See Restatement (Third) of the Law Governing Lawyers § 53 cmt. d ("A judgment in a postcon-viction proceeding is binding in the malpractice action to the extent provided by the law of judgments.”).
. At least one jurisdiction, California, requires that a malpractice plaintiff not only have had his conviction set aside as a prerequisite to filing a malpractice suit, but also that he then allege and prove “actual innocence" in the ensuing negligence action.
Coscia,
. Larsen also relies upon
Gebhardt v. O’Rourke,
. Counsel have ethical obligations to safeguard client files. See Ariz. R. Sup.Ct. 42, ER 1.15 and 1.16. Thus, unless different arrangements have been made with the client, criminal defense counsel routinely will retain client files well beyond the termination of representation. See Ariz. Comm, on Rules of Prof’l Conduct Op. 98-07 (June 3, 1998) (stating that indefinite retention of files "is appropriate in homicide, life sentence, and lifetime probation matters;” in "most other matters," file retention for five years after termination of representation is appropriate). Therefore, in most if not all malpractice cases arising out of criminal litigation, the lawyer will also have access to the case file in preparing a defense.
