delivered the Opinion of the Court.
We granted certiorari to review an unpublished opinion of the court of appeals, Michaelson v. Michaelson, No. 92CA0052 (Colo.App. April 22, 1993) (not selected for official publication). At issue is the preclusive effect of the property division in a 1965 divorce action on claims brought in the case now before us. The petitioner, Ruth Michaelson, brings this action against her former husband, Ervin Michaelson, seeking damages for his alleged mismanagement of a corporation in which the two were the sole stockholders.1 We find that the present action is not barred by res judicata or collateral estoppel and, accordingly, we reverse the decision of the court of appeals.
I.
Ruth and Ervin Michaelson were married in 1946. In 1952, they formed a Colorado corporation known as Michaelson’s Originals, Inc., in which each held fifty percent of the stock, or 2,500 shares each.
The couple was divorced in 1965 in a Denver District court action, but permanent orders dividing the marital property were not entered until 1989. The marital property was valued as of 1965 and divided under 1965 law.2
After the divorce decree was entered in 1965, Ervin Michaelson continued to conduct the business of Michaelson’s Originals, Inc. Ruth Michaelson moved out of state and had no contact with her former husband or the enterprise. The corporation, whose business concerned mainly real estate investment and development, continued until Ervin Michael-son wrongfully dissolved the corporation in 1987. A meeting was called in December 1987, at which the shareholders and directors voted to dissolve the corporation. Ruth Mi-chaelson, however, was not notified of this meeting and did not attend. Nor did she receive any distribution of the corporation’s assets, which exceeded one million dollars. Following the meeting, Ervin Michaelson filed fraudulent statements concerning the dissolution with the Secretary of State, reporting that the assets of the corporation had been distributed among all the shareholders according to their rights and interests. In addition to his wrongful dissolution of the corporation in 1987, Ervin Michaelson intentionally failed to pay taxes on some of the *698real property belonging to the corporation in order to buy it back and take Ruth Michael-son’s name off the deeds.
In February 1988, Ruth Miehaelson discovered that the corporation had been wrongfully dissolved. Later that year, she initiated proceedings for a permanent division of the marital property. Judge Rothenberg heard several days of testimony on the value of the property owned by the parties as of 1965, and on the relative fault of the two parties and, pursuant to 1965 law, issued the relevant orders.3
Judge Rothenberg valued each piece of property owned by the parties and by the corporation as of 1965 and divided the total of $517,917.00 equally between them. The court held: “All of this remaining property is awarded to Ervin Miehaelson. Ruth Mi-ehaelson is awarded one-half the value or $258,959.00.” The court also awarded interest to Ruth Miehaelson for the entire marital estate and described the interest alternatively as statutory or moratory interest. In awarding interest, the court noted Ervin Mi-chaelson’s wrongful withholding of funds and the significant time delay between the divorce decree and the property division. The court’s final lump sum award to Ruth Mi-ehaelson, including interest, totalled $800,-000.00. The court did not address the disposition of the shares of corporate stock in Michaelson’s Originals, Inc. held by the parties.
Pursuant to the court’s order, Ervin Mi-ehaelson paid the sum awarded to Ruth Mi-ehaelson. Ruth Miehaelson quitclaimed all of her interest in real property owned by the corporation to Ervin Miehaelson but did not tender her shares of the corporation. Ervin Miehaelson never made a demand for the tender of the shares. Judge Rothenberg’s order dividing the property was not appealed.
On December 13, 1990, Ruth Miehaelson filed the present action in Denver District Court against Ervin Miehaelson requesting an accounting and seeking damages as a shareholder of the corporation, based on claims of breach of fiduciary duty, fraud, and theft. Judge Peterson heard the case and rejected Ervin Michaelson’s res judicata and collateral estoppel claims, stating:
10. The gravamen of Defendant’s motion is that Plaintiffs claims are barred though [sic] the application of the doctrines of collateral estoppel and res judicata.
11. With respect to these issues the Court is inclined to agree with Plaintiff [Ruth Miehaelson]. What Judge Rothen-berg did in civil action No. B-68907 was to consider the actions of the Defendant as to his treatment of marital property from or relating back in time to the 1965 divorce decree. The Court then attempted to make an equitable distribution of the marital property. The law in effect at the time of the parties’ divorce required Judge Rothenberg to take into account the respective fault of Plaintiff and Defendant. The Court’s attempt at equity related only to the division of marital property between the parties.
12. The elements of the claims in this ease [90 CV 13033] concern different elements of proof, different remedies, and are based on Plaintiffs status as a principal in the corporation, rather than as a wife seeking distribution of marital assets. The Plaintiff hopes to punish the Defendant further.
She granted Ervin Michaelson’s motion for summary judgment on the fraud claim and later granted his motion to dismiss the claims for theft and accounting. The only issue remaining at trial was the claim for breach of fiduciary duty. At the conclusion of the trial, the court awarded Ruth Miehaelson $401,-008.00, plus prejudgment interest from December 11, 1987, in the amount of $137,-805.00, for a total judgment of $538,813.00. *699Costs of $4,136.00 were also awarded to her. Ervin Michaelson appealed.
The court of appeals vacated Judge Peterson’s judgment and remanded the case with directions to dismiss the action with prejudice. The court of appeals reasoned that Ruth Miehaelson’s claims to corporate assets and proceeds were barred because the rights of each party had been determined by Judge Rothenberg in the 1989 property division. Further, the court found that her claim of breach of fiduciary duty was barred because Judge Rothenberg’s award in the earlier property division proceeding, which was based on marital fault, considered Ervin Mi-chaelson’s improper disposal of some of the corporate assets and concluded that he had breached his fiduciary duty to the other stockholder, Ruth Michaelson. Finally, the court of appeals held that, because Ruth Michaelson had a full and fair opportunity to litigate her rights as a corporate shareholder during the property division proceeding, she was barred from relitigating those rights. According to the court of appeals, Judge Rothenberg’s ruling in the property division effectively removed any ownership interest of Ruth Michaelson in the corporation.
II.
The issue before us is the applicability of res judicata and collateral estoppel to the civil damage action heard by Judge Peterson.4 We hold that res judicata is inapplicable because Ruth Michaelson could not raise the issue of corporate mismanagement in the divorce proceeding. Collateral estoppel is inapplicable because the issue was neither actually litigated nor necessarily adjudicated in the prior ease.
A.
The doctrine of res judicata holds that an existing judgment is conclusive of the rights of the parties in any subsequent suit on the same claim. State Engineer v. Smith Cattle, Inc., 780 P.2d 546, 549 (Colo.1989); Pomeroy v. Waitkus, 183 Colo. 344, 350, 517 P.2d 396, 399 (1974). Res judicata constitutes an absolute bar to subsequent actions only when both the prior and subsequent suits have “identity of subject matter, identity of cause of action, and identity of capacity in the persons for which or against whom the claim is made.” Smith Cattle, Inc., 780 P.2d at 549; City of Westminster v. Church, 167 Colo. 1, 9, 445 P.2d 52, 55 (1968). The “same claim or cause of action” requirement is determined by the injury for which relief is demanded, and not by the legal theory on which the person asserting the claims relies. IB J. Moore, J. Lucas & T. Currier, Moore’s Federal Practice, ¶ 0.410(1) (2d Ed.1988) (“Generally, it has been held that a ‘cause of action’ is defined by the injury for which the claimant seeks redress and not by the legal theory on which the claimant relies.”).
Unlike the present Uniform Dissolution of Marriage Act, Colorado’s 1965 divorce law was premised on a finding of fault and permitted divorce only in limited situations.5 *700See, e.g., Schrader v. Schrader, 156 Colo. 521, 400 P.2d 675 (1965). The “injury,” under the 1965 law, was the fault providing grounds for the divorce. In her oral rulings, Judge Roth-enberg addressed the question of fault at several different points, and each time she found that both parties had been at fault. The written order found that “each of the parties has wronged the other party egregiously” and that there was “considerable fault by both parties.” Because both the divorce and the subsequent property division relate back to the 1965 divorce, only the adjudication of injuries arising before that date could properly be the basis for application of res judicata. Any injury which occurred subsequent to 1965 would be a new injury because the divorce decree already had been issued.
In his argument that res judicata does apply, Ervin Miehaelson contends that because the property division occurred in 1989, the court had jurisdiction to consider the wrongful dissolution of the corporation. He further asserts that the same subject matter is involved, as both claims involve the interests in the corporation and the corporation’s assets. Certainly, it is clear from the record that Judge Rothenberg did consider the interests in the assets of the corporation in the property division, and she did so because the corporation was the principal marital asset. However, Judge Rothenberg only considered the value of the assets as of 1965. Information regarding events that had occurred since 1965 such as sales or transfers of real property owned by the corporation was relevant to determine the value of the corporation in 1965. Expert testimony, for example, established the present value of the corporate assets and estimated the 1965 value of the assets by discounting the present value. Such testimony about corporate assets and other testimony of when and how Ervin Mi-chaelson handled the corporate assets was relevant to valuation of the marital property.
Any claims arising after the 1965 divorce were separate. Such claims could not and did not arise out of the marriage but rather arose from, the corporate relationship which continued for over twenty years after the marriage was dissolved. Thus, we conclude that Ruth Michaelson’s claim for a breach of fiduciary duty arising from the post-divorce corporate relationship was not barred by res judicata.
B.
Ervin Miehaelson also argues that, even if the court could not have properly heard the breach of fiduciary duty claim, it was still actually litigated.6 As such, he contends that Ruth Miehaelson should be es-topped from raising the breach of fiduciary duty claim in the case heard by Judge Peterson. Collateral estoppel precludes claims if:
(1) The issue precluded is identical to an issue actually litigated and necessarily adjudicated in the prior proceeding;
*701(2) The party against whom estoppel was sought was a party to or was in privity with a party to the prior proceeding;
(3) There was a final judgment on the merits in the prior proceeding;
(4) The party against whom the doctrine is asserted had a full and fair opportunity to litigate the issues in the prior proceeding.
City and County of Denver v. Consolidated Ditches Co., 807 P.2d 23, 32 (Colo.1991); Pomeroy, 183 Colo. at 350, 517 P.2d at 399. We hold that, because the breach of fiduciary duty claim based on mismanagement was neither actually litigated nor necessarily adjudicated in the divorce case, the requirements for collateral estoppel are not satisfied.
The issue was not actually litigated. In order for an issue to be litigated, the issue must have been raised by the parties in the prior action. Pomeroy, 183 Colo. at 350, 517 P.2d at 399. No issue is legally raised between parties unless one of them, by appropriate pleading, asserts a claim or cause of action against the other. Moore et ah, supra, ¶ 0.443[3]. See also Restatement (Second) of Judgments, § 27, comt. d (1982).7 The pleadings in the property division case do not include any allegations concerning breaches of fiduciary duties. Nor were any amendments to the pleadings made to add a breach of fiduciary duty claim.
In his brief, Ervin Michaelson points to two motions filed by Ruth Michaelson as evidence that the breach of fiduciary duty claim was pled. The first was a motion for appointment of a receiver to manage the parties’ properties and to collect rent and profits. This motion was denied by Judge Rothenberg as a drastic remedy which was not justified by any exigency. The motion itself did not allege a breach of fiduciary duty or assert that the corporation was wrongfully dissolved. It simply alleged, on information and belief, that the corporation had been dissolved and its assets sold without Ruth Miehaelson’s knowledge and that she had received no money from the transactions.
Similarly, the second motion, Ruth Mi-chaelson’s motion for permanent orders, made no allegation of breach of fiduciary duty. Ruth Michaelson did demand one-half of all marital property. With respect to the corporation, the motion stated:
Respondent is requesting past dividends and her dissolved percentage in the parties[’] corporation, Michaelson’s Originals, Inc., which was dissolved in violation of the Court’s order and without knowledge and notice to the Respondent.
The reference to a prior court order is unclear, but it apparently refers to temporary orders entered about the time when the parties were divorced in 1965.
Neither motion can be read fairly as pleading a breach of fiduciary duty and they were not so construed by the parties at the time of trial. In fact, the attorney for Ervin Mi-chaelson admitted in his rebuttal closing argument that wrongful dissolution of the corporation “doesn’t make any difference. Other than to the extent that it may have displayed motivation, Mr. Michaelson had all the property that was in the corporation on the table for consideration by the court.” The attorney continued, “So we have exactly the same amount of property here as if there had been no dissolution of the corporation.”' The statements of Ervin Miehaelson’s attorney demonstrate that even he thought the dissolution of the corporation was not relevant to the proceeding and, thus, was not actually litigated.
Further, the issue was not necessarily adjudicated. An issue is necessarily adjudicated when the determination of an *702issue was necessary to a judgment. Moore et al, supra, ¶ 0.443[4]. See People ex rel. Gallagher v. District Court, 666 P.2d 550 (Colo.1988). The issue must be identical to the issue that was actually and necessarily decided at a prior proceeding. People ex rel. Gallagher, 666 P.2d at 554.
Ruth Michaelson’s claim to the corporate assets in the property division arose from the marriage, not from her status as a corporate shareholder. Although Judge Rothenberg described Ruth Michaelson as a “creditor” and referred to Ervin Michaelson’s fiduciary responsibilities to her, those statements are probably better understood as imperfect analogies. In fact, Ruth Michaelson had a claim to the marital assets which was superi- or to that of a creditor. Tinglof v. Askerlund, 96 Colo. 27, 31, 39 P.2d 1039, 1040 (1934) (holding that a wife’s interest in property has priority over a general creditor); Stokes v. Dollard, 94 Colo. 206, 209, 29 P.2d 706, 707 (1934). “[F]rom marriage a wife has an inchoate interest in her husband’s property ‘equitable, though unadjudieated.’ ” Tinglof, 96 Colo. at 31, 39 P.2d at 1040 (quoting Stokes, 94 Colo. at 209, 29 P.2d at 707).
In this case, Judge Rothenberg found the corporation’s assets to be marital assets, and determined the value of those assets as of 1965. Any subsequent assets acquired by the corporation were not considered for the purposes of the property division. While it is true that Judge Rothenberg’s decision discusses the mismanagement of the corporation after 1965, no evidence in the record demonstrates that the court factored the mismanagement into the property division or its award of interest. The claimed breach of fiduciary duty based on mismanagement of the company is a different issue from the issue of fault during the marriage, and marital fault is all that Judge Rothenberg considered in dividing the property.
Ervin Michaelson also argues that Judge Rothenberg’s award of statutory interest pursuant to Section 5-12-102(1)8 demonstrates that the breach of fiduciary duty claims had been adjudicated because the “wrongful withholding” found by the court was the breach of fiduciary duty.9 Initially, we note that Judge Rothenberg found that Ervin Michaelson’s wrongful withholding of all income from marital assets under his control was the basis for awarding statutory interest. The actual award of interest was *703based on alternative grounds as either statutory or moratory interest.
The purpose of statutory interest is to discourage a person responsible for payment of a claim from delaying payment. Mesa Sand & Gravel v. Landfill, Inc., 776 P.2d 362, 364 (Colo.1989). Statutory interest represents a legislative determination that persons suffer a loss when they are deprived of property to which they are legally entitled. Id. The statutory interest law should not be strictly construed. Id. at 365; Isbill Associates, Inc. v. City & County of Denver, 666 P.2d 1117, 1121 (Colo.App.1983).
Judge Rothenberg’s primary concern in awarding interest was the inequity of making a property division twenty-two years after the divorce without any adjustment to account for the time value of the money. As such, the court found it was compelled to make adjustments for the parties and awarded interest as a form of compensation. If the interest adjustment were intended as an award of damages for a breach of fiduciary duty claim, the court would have included only the properties which were part of the corporation as the basis for calculating interest. Instead, the award of interest extended beyond the 1965 valuation of corporate holdings to include the children’s bank accounts, other marital property, and the various investments of the family. The court awarded interest because Ervin Michaelson had enjoyed the sole benefit of the bulk of the marital estate for twenty-two years and had not given any, much less one-half, of the income from the property to Ruth Michael-son. Such actions constituted wrongful withholding for purposes of the statutory interest award. All of the wrongful withholding of funds arose from unlawful retention of marital assets and income by Ervin Michaelson and not from mismanagement of the corporation.
We hold that the findings and conclusions of Judge Peterson are supported by the record and collateral estoppel does not preclude the breach of fiduciary duty claim because the issue was neither litigated nor necessarily adjudicated.
in.
We also granted certiorari to determine whether all interspousal claims must be joined in a dissolution of marriage action or whether such claims involve different issues requiring different trials. Because the property division proceeding relates back to the 1965 divorce decree and the mismanagement of the corporation occurred after that time, we have held here that the claim for breach of fiduciary duty is a completely separate issue. Because of the timing, i.e., the corporate mismanagement occurred after the dissolution of the marriage, it is not an inter-spousal claim. No interspousal claim existed at the time of the divorce which could have required joinder in the divorce action. Thus, under the facts of this case, the issue on which we granted certiorari is not properly presented. Accordingly, we dismiss certiora-ri as improvidently granted on this issue. Mancuso v. United Bank of Pueblo, 818 P.2d 732, 734 n. 1 (Colo.1991).
IV:
For these reasons, we reverse the judgment of the court of appeals. We remand this case to that court for consideration of the other appellate issues raised by the parties but not reached by the court of appeals in its original decision.
ROVIRA, C.J., dissents, and ERICKSON and LOHR, JJ., join in the dissent.. Both cases were filed in Denver District Court. The divorce action was B-68907 and the civil damage action was 90-CV-13033. Judge Sandra I. Rothenberg presided over the property division in B-68907, and Judge Connie L. Peterson presided over 90-CV-13033. For convenience, we will identify the two cases in the text of this opinion by reference to the presiding judge.
. Because the Uniform Dissolution of Marriage Act was enacted in 1971, it did not apply to the parties' divorce. See § 14-10-101 et seq., 6B C.R.S. (1987).
. In accordance with § 14-10-113(3), 6B C.R.S. (1987), the court valued and awarded the property as of the date of the divorce decree in 1965, using the applicable law of that time. See generally In re Questions Submitted by United States District Court, 184 Colo. 1, 517 P.2d 1331 (1974) ("at the time the divorce action was filed, there vested in the wife her interest in the property in the name of her husband”). As such, the court considered the parties' fault in awarding property. See, e.g., Schrader v. Schrader, 156 Colo. 521, 400 P.2d 675 (1965). The judge ruled that, because the parties were equally at fault, she would divide the property equally.
. We granted certiorari on the following questions:
1. Whether the court of appeals erred by substituting itself as the trier of fact and disturbing the findings of the trial court even though the facts were supported in the record.
2. Whether all interspousal claims, including tort and contractual claims, must be joined in a dissolution of marriage action or whether said claims involve different issues requiring separate trials.
3. Whether the court of appeals erred by applying doctrines of collateral estoppel and res judicata to the civil suit brought by petitioner based upon the fact that the parties were involved in a prior dissolution of marriage action.
The first and third issues are closely related and will be considered together.
. Section 46-1-1 of the 1965 law stated:
Grounds for divorce. — (l)(a) Any marriage may be dissolved and divorce granted for any one or more of the reasons set forth in this section and for no other cause:
(b) That the spouse from whom the divorce is sought was impotent at the time of the marriage, or became impotent through immoral conduct committed after marriage;
(c) That the spouse from whom the divorce is sought has committed adultery since the marriage;
(d) That the spouse from whom a divorce is sought has wilfully deserted the other spouse, without reasonable cause, for a period of one year, or more, immediately preceding the beginning of the action for divorce;
(e) That the spouse from whom a divorce is sought has been extremely and repeatedly cruel toward the other spouse; and such cruelty *700may consist of the infliction of mental suffering and bodily violence;
(f) That the husband, being in good bodily health, has failed to make reasonable provisions for the support of his family for a period of one year, or more, next prior to the beginning of the action for divorce;
(g) That the spouse from whom a divorce is sought has been an habitual drunkard or drug addict for a period of one year or more, next prior to the beginning of the action for divorce;
(h) That the spouse from whom a divorce is sought has been convicted of a felony in a court of record in any state, territory, federal district, or United States possession since marriage;
(i) That one spouse has been adjudicated an insane, mentally ill, or mentally deficient person, or a mental incompetent, not less than three years prior to the commencement of the action and has not, prior to the entry of decree of divorce, been adjudicated restored to reason or competency. No husband who secures a divorce on such ground, however, shall be relieved thereby from the duty of the support of the wife from whom he is thus divorced, unless she has sufficient property or means to support herself;
(j)That the parties have lived separate and apart for a period of three consecutive years, or more, next prior to the commencement of the action for divorce, by force of decree of a court of record in any state, territory, or United States possession or district.
(2) A divorce shall not in anywise affect the legitimacy of any child of a marriage, nor its right to inherit the property of its father or mother.
1963 C.R.S. § 46-1-1.
. As noted earlier, supra p. 697, Ervin Michael-son did not appeal Judge Rothenberg’s order.
. Comment d to Section 27 of the Restatement of Judgments states:
When an issue is properly raised, by the pleadings or otherwise, and is submitted for determination, and is determined, the issue is actually litigated within the meaning of this section [issue preclusion]. An issue may be submitted and determined on a motion to dismiss for failure to state a claim, a motion for judgment on the pleadings, a motion for summary judgment, ... a motion for directed verdict, or their equivalents, as well as on a judgment entered on a verdict. A determination may be based on a failure of pleading or of proof as well as on the sustaining of the burden of proof.
Restatement (Second) of Judgments, § 27 cmt. d. (1982) (emphasis added).
. Section 5-12-102 states, in relevant part:
(1) Except as provided in section 13-21-101, C.R.S., when there is no agreement as to the rate thereof, creditors shall receive interest as follows:
(a) When money or property has been wrongfully withheld, interest shall be an amount which fully recognizes the gain or benefit realized by the person withholding such money or property from the date of wrongful withholding to the date of payment or to the date judgment is entered, whichever first occurs; or, at the election of the claimant,
(b) Interest shall be at the rate of eight percent per annum compounded annually for all moneys or the value of all property after they are wrongfully withheld or after they become due to the date of payment or to the date judgment is entered, whichever first occurs ....
§ 5-12-102, 2 C.R.S. (1992).
. Judge Rothenberg's initial comments concerning interest were as follows:
33.The Court finds that the parties had several legal relationships other than as spouses. Not only was Mrs. Michaelson spouse to Mr. Michaelson, but she was also a creditor. The Court finds that the parties signed a partnership agreement about July 28, 1959, which made them equal partners. Thus, Mr. Mi-chaelson owed a fiduciary duty to Mrs. Mi-chaelson as a partner. Also, he owed her a fiduciary duty as he was president and director of Michaelson’s Originals, Inc., the family corporation in which she was 50 percent shareholder.
34. The Court finds that Mrs. Michaelson is a creditor within the meaning of C.R.S. 5-12— 102 and that she was damaged by Mr. Michael-son. He wrongfully withheld monies after they became due. He filed false and misleading documents with the Colorado Secretary of State which failed to identify Mrs. Michaelson as equal shareholder and partner.
35. Finally, Mr. Michaelson admitted that he allowed their joint property to go to tax sale in order to get Mrs. Michaelson’s name removed from the deeds.
36. The court therefore finds that statutory interest is appropriate in this case.
37. Assuming, arguendo, that statutory interest is not appropriate, the Court finds that moratory interest is appropriate. Davis Cattle, Inc. v. Great Western Sugar Company, 393 F.Supp. 1165 (Colo.1975), because Mrs. Mi-chaelson has suffered delays in payment and loss of the use of the property.
