    Linda WILSON, Plaintiff-Appellant, v. Matthew KANE, Jr., Defendant-Appellee.
    No. 76587.
    Supreme Court of Oklahoma.
    May 11, 1993.
    
      Gary L. Bracken, Ponca City, for plaintiff-appellant.

   OPALA, Justice.

The dispositive question here is whether Linda Wilson’s [plaintiff’s or Wilson’s] claim against Matthew Kane, Jr. [Kane], personal representative of her uncle’s estate, for his alleged “conversion” of certain nonprobate assets by mismanagement could have been litigated in probate. We answer this question in the negative. The remedial deficiency of probate procedure to accommodate Wilson’s claim prevents the probate adjudications on which Kane relies from having res judicata (also known as claim preclusion) effect.

I.

THE ANATOMY OF LITIGATION

A.

THE PROBATE PROCEEDING

Wilson’s uncle [the uncle] bought certificates of deposit [certificates] for $130,-000.00, payable to Wilson upon his death. He also named Wilson a beneficiary of his will and joint tenant in a checking account. When the uncle died, the certificates were delivered to Kane, the estate’s personal representative. Kane allowed them to mature; then he cashed the certificates and deposited the proceeds in the estate’s non-interest bearing account. Over a year after her uncle’s death, Wilson learned from the bank’s president that she was the certificates’ POD (payable on death) beneficiary.

When Wilson sought in probate to recover the certificates’ proceeds, the estate contested her claim. After a hearing in probate, the judge (1) decreed Wilson to be the owner of the certificates and of a joint checking account and (2) ordered the proceeds from the certificates and from the account to be turned over to her. A second probate order approved a settlement that divides the checking account proceeds between Wilson and her two cousins (beneficiaries under the uncle’s will) and made unappealable the earlier probate order. The certificate proceeds went to Wilson. Her lawyer approved Kane’s final account; while sitting in probate the judge issued a decree of distribution and discharged Kane from his duties as the estate’s personal representative.

B.

WILSON’S CLAIM FOR KANE’S ALLEGED “CONVERSION” OF NON-PROBATE ASSETS BY MISMANAGEMENT

Later Wilson brought this action against Kane. She contends his mismanagement of her certificates (nonprobate assets) cost her not only -interest that the certificates could have earned while they languished in the estate’s non-interest bearing account but a large attorney’s fee as well. The trial court gave summary judgment to Kane, believing that res judicata bars Wilson’s claim because it could have been litigated (a) in probate during the dispute over the certificates’ ownership or (b) as a challenge to the decree of distribution or to the personal representative’s discharge. Wilson appealed; the Court of Appeals affirmed the trial court's summary judgment and we granted certiorari.

c.

THE CONTROVERSY

Wilson contends the doctrine of res judicata does not bar her claim against Kane for converting nonprobate assets and urges that the probate order that discharges him from his duties as the estate’s personal representative does not exonerate Kane from liability for mismanagement of the certificates. According to Kane, since only one controversy arises from his dealings with the certificates, any and all recovery to which Wilson might have been entitled could have been litigated in probate during the dispute over the certificates’ ownership. Kane believes that his discharge in probate (as personal representative of the uncle’s estate) fully absolves him of any responsibility to Wilson.

II.

WILSON’S CLAIM FOR KANE’S ALLEGED CONVERSION OF NON-PROBATE ASSETS BY MISMANAGEMENT LIES DEHORS THE ADJUDICATIVE RANGE OF A COURT SITTING IN PROBATE

Wilson’s claim for alleged conversion of nonprobate assets by mismanagement, pressed for the first time in this action, is fit for the district court’s process of ordinary judicature, but not for resolution in probate. A probate proceeding moves along a procedural track vastly dif-' ferent from that followed by a regular “action” upon a claim. The latter is governed by the Pleading Code and is regulated by the rules of practice applicable to the ordinary process of adjudication. Before the Judicial Article of the Oklahoma Constitution and the provisions of § 91.-1 became effective on January 13, 1969, the remedial track for probate had its point of inception in the since-defunct county court. Although probate now begins and ends in district court, interdocket remedial boundaries survive. Probate is a special statutory proceeding. Its mainstream issues, procedural stages, and special statutory remedies remain the same as they were before 1969. The law confines them to: (1) ascertaining whether decedent died testate or intestate, and if testate, (2) what testamentary disposition, if any, may be admitted to probate, (3) the administration of the estate’s assets and (4) the final account and distribution.

Wilson’s claim for alleged conversion of nonprobate assets (later adjudged as her property) does not fit within probate’s statutorily limited framework. The relief she seeks (interest and other out-of-pocket losses) is for Kane’s alleged mismanagement of her personal property, not of that which belongs to the estate. Demands for a money judgment for one’s dealings with assets dehors the estate are not within the limited arsenal of special remedies affordable in probate.,

Under the doctrine of res judica-ta, a final judgment on the merits of an action bars the parties from relitigating not only the adjudicated claim but also any theories or issues that were actually decided or could have been decided in that action. For probate adjudications the effect of res judicata is circumscribed by the reality of our interdocket boundaries and by the statutes that narrowly craft probate as a special remedy. Where, as here, the claim sought to be litigated lay dehors probate and could not have been accommodated by its restricted framework, res judicata effect may not be accorded to the earlier orders in probate. In short, Wilson’s claim survives as a viable demand and the summary judgment for Kane cannot stand.

hi.

WILSON’S FAILURE TO CHALLENGE IN PROBATE EITHER THE DECREE OF DISTRIBUTION OR KANE’S DISCHARGE AS PERSONAL REPRESENTATIVE DOES NOT BAR HER CLAIM AGAINST HIM FOR ALLEGED CONVERSION OF NONPROBATE ASSETS BY MISMANAGEMENT

Had Wilson attempted to cast her demand for alleged conversion of nonprobate assets as an objection to the decree of distribution or to the personal representative’s discharge, as Kane urges she should have done, the court below would have been compelled to declare her claim irremediable in probate. It would have been indeed an act of supererogation for Wilson to have pressed a demand for which no redress was affordable.

A personal representative is responsible for the faithful administration of the estate’s property and may be surcharged for mismanagement of estate assets. Sitting in probate a judge can require a personal representative to account, in his fiduciary capacity, only for funds and property coming into his hands which are assets of the estate.

Wilson does not seek to hold the personal representative liable for wrongful administration or mismanagement of the estate’s assets. Rather, the redress sought here is for alleged mismanagement of her nonprobate assets. She has no quarrel with the decree of distribution; her demand may not be- viewed as a collateral attack on that decree. Since Wilson’s claim against Kane is litigable solely de-hors probate, she had no duty to call it to the attention of the judge in probate by interposing a challenge to the final decree or to Kane’s discharge.

SUMMARY

Wilson’s claim cannot be barred for her failure to make an irremediable demand. Her claim for Kane’s alleged conversion of nonprobate assets by mismanagement clearly was not litigable in probate. Inter-docket boundaries and narrowly drawn statutory remedies limit the remedial range of probate. They require that Wilson be allowed to press her claim in an ordinary action dehors probate. Neither res judica-ta nor issue preclusion bars this action. Summary judgment for Kane cannot stand.

WATT, Justice,

dissenting.

I dissent because I believe the majority has failed to give effect to the changes in the jurisdiction of district courts brought about by the court reform amendments to the Oklahoma Constitution in 1967. Okla. Const. Art. 7 § 7(a) provides in material part:,

The District Court shall have unlimited original jurisdiction of all justiciable matters, except as otherwise provided in this Article

Although the district court was acting within its probate docket, I think it inescapable that it had jurisdiction in the probate proceeding to consider Wilson’s tort claims against Kane. I would therefore hold that Wilson’s tort action was barred by res judi-cata.

The majority holds that Wilson’s tort claim “is [not] fit for ... resolution in probate,” but carefully avoids holding that the first district court lacked jurisdiction in the probate action to dispose of all matters in dispute between Wilson and Kane. I disagree with the majority’s refusal to deal with the jurisdictional issue. Disputes over the jurisdiction of district courts acting in their probate capacity have created much confusion in the Oklahoma law since 1969. By refusing to deal with this issue, the majority leaves an already murky area more unsettled.

Historical Background

In 1967 the people reformed the Oklahoma court system by amending the Judicial Article of the Oklahoma Constitution to grant “unlimited original jurisdiction” to the district courts and eliminate the other courts that had existed since statehood. Id., Article 7, § 7(a). The legislature amended the statutes to reflect these changes in legislation that became effective in January 1969.

Before court reform, the jurisdiction of county courts was strictly limited. Any decision of a county court in a probate matter was appealable to the district court for trial de novo. The county court lacked jurisdiction to decide title to property in non probate actions.

Court reform was thought to have eliminated confusion over competing jurisdiction of the sort that arose in State v. Lohah, 434 P.2d 928 (Okla.1967). There, we issued a writ of prohibition to resolve a dispute between a district court, sitting in a divorce action, and a county court, sitting in a dependant and neglected child matter. Professor George B. Fraser predicted the effect of court reform in an article he wrote about the changes in the Oklahoma Law Review:

Since there will be only one trial court of general jurisdiction the problem of which court has jurisdiction of an action will no longer exist and conflicts between courts within a county will no longer be possible_ [Emphasis added.]

Fraser, Oklahoma’s New Judicial System, 21 Okla.L.Rev. 373, 374 (1968).

We echoed Professor Fraser’s sentiments in the first case in which we addressed the effect of § 7(a), In re Estate of Faulkner, 504 P.2d 875, 877 (Okla.1972). In Faulkner, this Court held:

The District Court is no longer limited by the rule that in probate matters its jurisdiction is appellate only and embraces only the jurisdictional scope of a county court sitting in probate matters.

We have recognized the effect of § 7(a) in two recent opinions. In Frazier v. Bryan Memorial Hosp. Authority, 775 P.2d 281, 285 (Okla.1989), we said, “The district court stands in our constitutional order as a judicial tribunal of unlimited jurisdiction.” [Emphasis as in the original.] In Eskridge v. Ladd, 811 P.2d 587, 588 (Okla.1991), we said that, under Article 7, § 7(a) of the constitution, the district court is “omnicompetent.” [Emphasis added.]

In Duke v. Nelson, 536 P.2d 412, 414 (Okla.App.1975), the Court of Appeals took a position contrary to Faulkner, without citing it. There, the court said:

The new Judicial Article [20 O.S. 1981 § 91.1] did not abolish nor alter the distinction between various types of court actions whether established by common law or statutes. Probate proceedings are strictly statutory. The purview of probate proceedings in Oklahoma will be the same in the -District Court as they were in the County Court unless changed by statute.

The Duke court’s language was not only a misstatement of the law, it was unnecessary to the Court of Appeals’ holding. In Duke, defendant had demurred to plaintiff’s petition on the ground that another action was pending. The Court of Appeals held that the trial court had improperly sustained defendant’s demurrer because plaintiff’s petition did not allege this fact. The Court of Appeals in Duke not only ignored Faulkner but relied on In re Griffin’s Estate, 199 Okla. 676, 189 P.2d 933 (1947), which was decided before court reform.

The next year, we decided one case that was in line with Faulkner, and another that followed Duke. In re Woodward, 549 P.2d 1207 (Okla.1976), apparently followed Faulkner, and In re Estate of Kizziar, 554 P.2d 791 (Okla.1976) cited with approval the unfortunate misstatement of the law from Duke.

In re Woodward, 549 P.2d 1207 (Okla.1976), was an action to determine the death of a joint tenant and to terminate the joint tenancy. Defendants, other relatives of the decedent, filed a counterclaim in which they contended the plaintiffs had secured the joint tenancy deed through fraud and undue influence. The trial court tried the matter and found for plaintiffs and against defendants on defendants’ counterclaim. Apparently other parties were involved in the action who were not heirs or devisees of the decedent. By affirming the trial court, we impliedly recognized the power of the district court to try title to real property while sitting in its probate capacity, although some of the parties were not heirs.

In re Estate of Kizziar, 554 P.2d 791 (Okla.1976) started out as the probate of the estate of an intestate. During his lifetime, decedent had bought certificates of deposit on which he named others as joint tenants. The surviving joint tenants in the certificates of deposit objected to the personal representative’s inventory, and the trial court held an evidentiary hearing to decide whether the estate or the surviving joint tenants owned the certificates. In the final decree, the trial court held that the estate, not the surviving joint tenants, owned the certificates of deposit. The surviving joint tenants appealed. This Court cited Duke with approval, and held that the trial court had lacked jurisdiction to decide the ownership of the certificates of deposit. As had Duke, Kizziar relied on cases decided before court reform. Kizziar recognized the exception created by In re Griffin’s Estate, 199 Okla. 676,. 189 P.2d 933 (1947). Griffin held that a probate court had jurisdiction to try title if the dispute is between those claiming as heirs or devisees of the decedent. In Kizziar, however, we held that the Griffin exception did not apply because, in Kizziar, the surviving joint tenant was a stranger to the estate.

In the seventeen years since it was decided, this Court did not cite Kizziar, until the majority did so today. It has been cited but twice by the Court of Appeals, in Matter of Lindell’s Death, 573 P.2d 716 (Okl.App.1977), and Matter of Estate of Jech, 701 P.2d 428 (Okl.App.1985). Both opinions were justifiably critical of Kizziar. In Lindell, the Court of Appeals properly concluded that it was bound by Kizziar,. and Duke, but suggested their holdings were inconsistent with court reform:

... We can see no law or logical reason why a district court in Oklahoma cannot determine all of the issues in a case without the necessity of at least two separate actions being filed
As we see it, the only possible rationale for the cases which conclude that the district court must sit in a dual capacity — that is, hear two separate lawsuits— is because originally there were two separate courts which now have become one.... This seems to go against the very letter and spirit of the statutory court reform in Oklahoma. [Emphasis added.]

Lindell, Id. 573 P.2d at 720. In Jech, the Court of Appeals after noting that it was bound by Kizziar and Duke, quoted Lin-dell with approval.

Resolving the Confusion

Today the majority has failed to resolve the confusion, spawned by Kizziar and Duke, that has existed with respect to the jurisdiction of district courts in probate matters. Kizziar relies on a misstatement in Duke and misapplies the law. I would overrule Kizziar. Wilson submitted herself to the jurisdiction of the first district court by claiming the certificates of deposit in that forum. She should have been required to submit all claims arising from the central facts of the transaction there. Subjecting Kane to a second suit arising out of the same transaction, because Wilson's first suit was assigned a probate number, is unfair and not supported by law.

The majority cites Kizziar, but avoids applying it by saying that the jurisdiction of the court in the Morris probate to decide that matter is not before this Court. I believe the jurisdiction of the probate court is properly before the Court. If the district court had jurisdiction over the parties and the subject matter of Wilson’s claim to the certificates, how could it lack jurisdiction over the remaining issues arising from the transaction between Wilson and Kane? On the other hand, if the trial court in the Morris probate lacked jurisdiction to consider who owned the certificates of deposit, then the judgment in Wilson’s favor was a nullity. Thus, Wilson will be required upon remand of this action to again prove that she owned the Certificates. Wilson will have to win on the ownership issue a second time to entitle herself to damages. Leaving the critical question of the first district court’s jurisdiction unanswered virtually guarantees that we will see this case again.

Believing as I do that Kizziar should be overruled, and that we should hold the trial court had jurisdiction over Wilson’s claim in the Morris probate matter, her claim in this action was barred by res judicata. Under Mann v. State Farm Mutual Auto. Ins. Co., 669 P.2d 768 (Okla.1983), and Retherford v. Halliburton Company, 572 P.2d 966 (Okla.1977), a cause of action includes all theories arising from a single occurrence or transaction. That is the case here.

The majority repeatedly uses the term “probate judge” as if a probate judge were somehow different from other district judges. One searches the constitution and statutes in vain for the term “probate judge.” The constitution and statutes do not mention “probate judge.” Instead, they create a single district court that is “omnicompetent.” The majority’s holding to the contrary is insupportable.

The trial court and the Court of Appeals correctly decided the matter. The failure of the majority to overrule Kizziar regrettably deprives the people of this state of a significant amount of the reform they thought they were getting when they passed Court Reform in 1967. The majority’s pronouncement is unsupported by either “law or logical reason” and goes “against the very letter and spirit of the statutory court reform in Oklahoma.” Lindell, Id. 573 P.2d at 720. Unfortunately, the confusion over the jurisdiction of district courts sitting in probate matters to try title to property that has existed since Kizziar still reigns. I dissent. 
      
      .Wilson characterizes her theories of recovery as "negligence, conversion and breach of fiduciary duty against a personal representative of an estate in connection with his handling of certificates of deposit that belonged to the plaintiff and were not properly part of the estate." [Emphasis supplied.] Whether Wilson’s claim is actionable or whether her evidence will support the quest for relief under any of these theories is not before us today. For the sake of simplicity we refer to Wilson’s claim as one for Kane’s alleged “conversion" of non-probate assets by mismanagement.

      Wilson argues that "the trial court erred in ruling that the doctrine of res judicata or collateral estoppel barred [her] claim.” The doctrines of res judicata and collateral estoppel are not interchangeable. See Panama Processes, supra at 283-284 n. 27.
      The Restatement of Judgments describes collateral estoppel as "issue preclusion." See Restatement, supra note 11 at § 27; Veiser, supra note 22 at 799 n. 7; Oklahomans for Life, supra note 22 at 706-707. See abo Allen, supra note 22, 449 U.S. at 94, 101 S.Ct. at 415; Migra, supra note 22, 465 U.S. at 76, 104 S.Ct. at 894; Mendoza, supra note 22, 464 U.S. at 157, 104 S.Ct. at 571. Under bsue preclusion, once a court has decided an bsue of fact or law necessary to its judgment, that bsue may not be relitigated between the same parties or their privies in a suit on a different cause of action. Veber, supra note 22 at 800 n. 9. See Allen, supra note 22; Montana v. United States, 440 U.S. 147, 153, 99 S.Ct. 970, 973, 59 L.Ed.2d 210 (1979);
      
        No bsue in Wibon's claim was ever presented at any stage of the earlier proceeding in probate; collateral estoppel b hence clearly inapplicable to bar any of these bsues.

      . Boudinot v. Locust, 55 Okl. 662, 151 P. 579, 582 (1915), aff'd. on rehearing 155 P. 698 (1916); Judge v. Tyson, 42 Ala. 401 (1868). The disposi-tive question is whether the personal representative was entitled to receive the money or property in his capacity as administrator. If not, the judge sitting in probate has no power to require him to account for those assets. An order requiring the personal representative to account might be condemned as void. An exception to this rule may apply when a judge mistakenly orders the administration of a nonprobate asset under the erroneous belief it belonged to the estate. Boudinot, supra 151 P. at 582.
      
        The general rule, rather than the exception, governs this case. The certificates Wilson claimed as her own were never judicially declared as probate assets.
      
     
      
      .The trial judge mistakenly viewed Wilson’s claim as an attack on the decree of distribution and on the personal representative’s administration of the estate in probate. He rested summary judgment for Kane upon (1) the text of 58 O.S.1981 § 632, which provides that the final decree is “conclusive as to the rights of heirs, legatees or devisees, subject only to be reversed, set aside, or modified on appeal" (2) the terms 58 O.S. 1981 § 691, which provide that when the personal representative has "performed all the acts lawfully required of him, the court must make a judgment or decree discharging him from all liability to be incurred thereafter and (3) the teachings of O’Neill v. Cunningham, 119 Okl. 157, 244 P. 444, 447 (1926) and Coyne’s Estate, 103 Okl. 279, 229 P. 630, 633 (1924), which hold that a personal representative is protected from personal liability by the decree of distribution if he has acted reasonably and in good faith in the disbursement of money pursuant to the decree. [Emphasis provided.]
      Wilson’s claim is not barred by the adjudications made in probate; her quest for monetary recovery could not have been redressed in that special proceeding.
