Tyrone Williams (“Williams”) and WHF, Inc. of Virginia (“WHF”) (together, “Plaintiffs”) filed suit against Annittie Peabody (“Peabody”) and Peabody’s Home Improvements, Inc. (together “Defendants”) subsequent to a similar lawsuit involving some but not all of the same parties. Upon motion by Defendants, the trial court granted summary judgment in favor of Defendants on the grounds of res judicata and collateral estoppel. We must determine whether Plaintiffs’ lawsuit was correctly dismissed pursuant to the doctrines of res judicata and collateral estoppel. We affirm the trial court’s order dismissing Williams’ lawsuit against Defendants. However, we reverse the trial court’s order dismissing WHF’s lawsuit against Defendants and remand for additional evidence.
The evidence of record tends to show that Williams and Crystal Williams were at all times relevant to these proceedings husband and wife and managers of Platinum Lions Group, LLC., and WHF, Inc. of Virginia. Peabody is the sole shareholder and officer of Peabody’s Home Improvements, Inc.
On 3 April 2008, Williams changed the registered agent of Peabody’s Home Improvements, Inc., from Peabody to Williams by allegedly forging Peabody’s signature on a Change of Registered Office and/or Registered Agent form, which stated that Williams was the new registered agent and president of Peabody’s Home Improvements, Inc.
*3On 1 October 2008, Williams, allegedly misrepresenting himself as the president of Peabody’s Home Improvements, Inc., signed four general warranty deeds purportedly granting Platinum Lions Group, LLC, a fee simple interest in four properties owned by Peabody’s Home Improvements, Inc. On 4 October 2008, Williams allegedly forged the signature of Crystal Williams, his wife and the president of Platinum Lions Group, LLC, on an additional four general warranty deeds referencing the same four properties, which supposedly granted Crystal Williams a fee simple interest in the properties. The record also contains one additional general warranty deed, filed on 3 April 2009, which purportedly conveyed title to three of the same four properties from Crystal Williams to WHF.
On 10 November 2008, Peabody’s Home Improvements, Inc., filed a complaint and action to quiet title (File # 08 CVS 11281) (“original lawsuit”) against Williams, Crystal Williams, and Platinum Lions Group, LLC, alleging claims for fraud, conspiracy to commit fraud, and unfair and deceptive trade practices.
On 15 January 2009, Williams filed a motion to dismiss the complaint alleging the following: “[T]he action . . . involve[d], at best, an intracorporate dispute between shareholders [of Peabody’s Home Improvements, Inc.]”; Peabody lacked standing and corporate authority to file the complaint; Williams was the president and sole shareholder of Peabody’s Home Improvements, Inc.; Williams, as president of Peabody’s Home Improvements, Inc., executed general warranty deeds conveying title to the four aforementioned properties; Williams “does not desire that his wholly owned corporation . . . sue him and has not authorized it to sue him.” Williams asserted no counterclaims.
On 12 March 2010, Williams filed a response to Peabody’s request for admissions, in which Williams admitted he signed Peabody’s name to the Change of Registered Office and/or Registered Agent form. However, Williams claimed to have signed it with Peabody’s assent and permission.
Also on 12 March 2010, Williams filed an affidavit which ostensibly contradicted his assertions in the motion to dismiss by stating that Peabody’s Home Improvements, Inc., is “sole[ly] operated by Annittie Peabodyf.]” Williams also stated in the affidavit that he placed $100,000.00 in an account Peabody opened in the name of Peabody’s Home Improvements, Inc., and these monies were used to purchase the four properties. Williams asserted that to quiet title such *4that Peabody’s Home Improvements, Inc., owned the four properties would unjustly enrich Peabody and be grossly inequitable.
Peabody’s Home Improvements, Inc., filed a motion for summary judgment, which the trial court granted on 19 March 2010. Williams did not appeal this order.
On 24 March 2010, Plaintiffs filed a complaint (File # 10 CVS 2682) (“present lawsuit”) against Defendants, alleging unjust enrichment and requesting injunctive relief to restrain Defendants from selling the four properties.
On 1 June 2010, Defendants filed an answer and moved to dismiss Plaintiffs’ complaint on grounds of res judicata and collateral estoppel. On 21 June 2010, the trial court entered an order granting summary judgment in favor of Defendants on grounds of res judicata and collateral estoppel. From this order, Plaintiffs appeal.
I: Summary Judgment
Plaintiffs’ argument on appeal is that the trial court erred by entering summary judgment against Plaintiffs because the doctrines of res judicata and collateral estoppel do not apply.
Summary judgment is properly granted “if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that any party is entitled to a judgment as a matter of law.” N.C. Gen. Stat. § 1A-1, Rule 56(c) (2009). “A defendant may show entitlement to summary judgment by: (1) proving that an essential element of the plaintiff’s case is nonexistent, or (2) showing through discovery that the plaintiff cannot produce evidence to support an essential element of his or her claim, or (3) showing that the plaintiff cannot surmount an affirmative defense which would bar the claim.” Carcano v. JBSS, LLC, 200 N.C. App. 162, 166, 684 S.E.2d 41, 46 (2009) (quotation omitted). Res judicata and collateral estoppel are affirmative defenses. N.C. Indus. Capital, LLC v. Clayton, 185 N.C. App. 356, 374, 649 S.E.2d 14, 26 (2007).
“An appeal from an order granting summary judgment solely raises issues of whether on the face of the record there is any genuine issue of material fact,- and whether the prevailing party is entitled to judgment as a matter of law.” Carcano, 200 N.C. App. at 166, 684 S.E.2d at 46. (citation omitted). “We review a trial court’s order granting or denying summary judgment de novo.” Craig v. New Hanover Cty. *5Bd. of Educ., 363 N.C. 334, 337, 678 S.E.2d 351, 354 (2009). “Under a de novo review, the court considers the matter anew and freely substitutes its own judgment for that of the lower tribunal.” Id. (quotation omitted). Our review, however, “is necessarily limited to whether the trial court’s conclusions as to the[] questions of law were correct ones.” Ellis v. Williams, 319 N.C. 413, 415, 355 S.E.2d 479, 481 (1987).
In the trial court’s order granting Defendants’ motion for summary judgment, the trial court made the following conclusion:
The court finds as a matter of law and pursuant to the doctrinéis] of res judicata and collateral estoppel that all issues involving the parties related to this subject suit were decided in Peabody’s Home Improvements Inc. v. Tryone Williams et al. (Cumberland County File No.: 08-CVS-11281) and the Plaintiff is therefore estopped from asserting this new lawsuit.
As such, our review is limited to whether the doctrines of res judicata and collateral estoppel were correctly applied.
II: Res Judicata and Collateral Estoppel
“The doctrines of res judicata (claim preclusion) and collateral estoppel (issue preclusion) are companion doctrines which have been developed by the Courts for the dual purposes of protecting litigants from the burden of relitigating previously decided matters and promoting judicial economy by preventing needless litigation.” Little v. Hamel, 134 N.C. App. 485, 487, 517 S.E.2d 901, 902 (1999) (quotation omitted).
“Under the doctrine of res judicata or ‘claim preclusion,’ a final judgment on the merits in one action precludes a second suit based on the same cause of action between the same parties or their privies.” Whitacre P’ship v. BioSignia, Inc., 358 N.C. 1, 15, 591 S.E.2d 870, 880 (2004) (citation omitted). “For res judicata to apply, a party must show that the previous suit resulted in a final judgment on the merits, that the same cause of action is involved, and that both the party asserting res judicata and the party against whom res judicata is asserted were either parties or stand in privity with parties.” State ex rel. Tucker v. Frinzi, 344 N.C. 411, 413-14, 474 S.E.2d 127, 128 (1996) (quotation omitted). “The doctrine prevents the relitigation of all matters ... that were or should have been adjudicated in the prior action.” Whitacre P’ship, 358 N.C. at 15, 591 S.E.2d at 880 (quotation omitted).
*6Under the doctrine of collateral estoppel, or issue preclusion, “a final judgment on the merits prevents relitigation of issues actually litigated and necessary to the outcome of the prior action in a later suit involving a different cause of action between the parties or their privies.” Frinzi, 344 N.C. at 414, 474 S.E.2d at 128. A party asserting collateral estoppel is required to show that “the earlier suit resulted in a final judgment on the merits, that the issue in question was identical to an issue actually litigated and necessary to the judgment, and that both the party asserting collateral estoppel and the party against whom collateral estoppel is asserted were either parties to the earlier suit or were in privity with parties.”1 Id. at 414, 474 S.E.2d at 128-29.
“In general, a cause of action determined by an order for summary judgment is a final judgment on the merits.” Green v. Dixon, 137 N.C. App. 305, 310, 528 S.E.2d 51, 55, aff'd per curiam, 352 N.C. 666, 535 S.E.2d 356 (2000). The parties in the present case do not dispute that a final judgment on the merits was entered in the original lawsuit.
i: Collateral Estoppel
We first address whether the trial court erred by barring Plaintiffs’ action on grounds of collateral estoppel. We conclude the trial court erred.
For purposes of collateral estoppel, “the prior judgment serves as a bar only as to issues actually litigated and determined in the original action.” City of Asheville v. State, 192 N.C. App. 1, 17, 665 S.E.2d 103, 117 (2008), appeal dismissed, disc. review denied, 363 N.C. 123, 672 S.E.2d 685 (2009) (quotation omitted) (emphasis in original). “[A]n issue is actually litigated, for purposes of collateral estoppel or issue preclusion, if it is properly raised in the pleadings or otherwise submitted for determination and [is] in fact determined.” Id. (quotation omitted). “A very close examination of matters actually litigated must be made in order to determine if the underlying issues are in fact identical[;] [i]f they are not identical, then the doctrine of collateral estoppel does not apply.” Id.
In the original lawsuit in this case, Peabody’s Home Improvements, Inc., brought suit against Williams, Crystal Williams, and Platinum *7Lions Group, LLC, alleging causes of action to quiet title, for unfair and deceptive trade practices, fraud, and conspiracy to commit fraud. The defendants in the original lawsuit did not assert counterclaims. In the present lawsuit, Plaintiffs brought suit against Defendants alleging unjust enrichment and praying for injunctive relief. No determination was made regarding unjust enrichment or injunctive relief in the original final judgment on the merits. We conclude the issues in the present lawsuit were not actually litigated in the original lawsuit, and therefore, collateral estoppel does not bar Plaintiffs’ action. The trial court erred by entering summary judgment because Plaintiffs’ claims were barred by collateral estoppel.
ii: Res Judicata: Estoppel of Claims
We next address whether Plaintiffs’ claims were estopped on principles of res judicata. Res judicata “bars every ground of recovery or defense which was actually presented or which could have been presented in the previous action.” Goins v. Cone Mills Corp., 90 N.C. App. 90, 93, 367 S.E.2d 335, 336-37, disc. rev. denied, 323 N.C. 173, 373 S.E.2d 108 (1988). A final judgment “operates as an estoppel not only as to all matters actually determined or litigated in the prior proceeding, but also as to all relevant and material matters within the scope of the proceeding which the parties, in the exercise of reasonable diligence, could and should have brought forward for determination.” Rodgers Builders, Inc. v. McQueen, 76 N.C. App. 16, 22, 331 S.E.2d 726, 730 (1985), disc. review denied, 315 N.C. 590, 341 S.E.2d 29 (1986) (citation' omitted). “A party is required to bring forth the whole case at one time and will not be permitted to split the claim or divide the grounds for recovery; thus, a party will not be permitted, except in special circumstances, to reopen the subject of the . . . litigation with respect to matters which might have been brought forward in the previous proceeding.” Id. at 23, 331 S.E.2d at 730. “The defense of res judicata may not be avoided by shifting legal theories or asserting a new or different ground for relief[.]” Id. at 30, 331 S.E.2d at 735.
The plea of res adjudicata applies,... not only to the points upon which the court was required by the parties to form an opinion and pronounce a judgment, but to every point which properly belonged to the subject in litigation and which the parties, exercising reasonable diligence, might have brought forward at the time and determined respecting it.
*8Edwards v. Edwards, 118 N.C. App. 464, 472, 456 S.E.2d 126, 131 (1995) (quotation omitted).
Plaintiffs argue on appeal that “the issues in the first suit... were different!)] • • • and the issues raised in the [present lawsuit] were not relevant and material to the first ligitationf.]” We are not persuaded. At the heart of both the original and present lawsuits lies a dispute regarding the four properties. In the original lawsuit, Peabody’s Home Improvements, Inc., alleged the deeds conveying title were “deceptively and fraudulently executed].]” In the present lawsuit, Plaintiffs alleged “the funds of the Plaintiffs were the sole source of revenue for acquisition of the properties.” We believe Plaintiffs’ claims in the present lawsuit are claims which Plaintiffs, exercising reasonable diligence, might have brought forward at the time of the original lawsuit. Thus, assuming arguendo Plaintiffs and Defendants in the present lawsuit satisfy the requirement of identity of parties, Plaintiffs’ claims are barred by res judicata.
iii: Res Judicata: Identity of Parties
We now address whether Plaintiffs and Defendants in the present lawsuit are the same or in privity with the parties to the original lawsuit. “[B]oth the party asserting res judicata and the party against whom res judicata is asserted [must be] either parties or stand in privity with parties” to the original action. Frinzi, 344 N.C. at 414, 474 S.E.2d at 128. “In general, privity involves a person so identified in interest with another that he represents the same legal right.” Whitacre P’ship, 358 N.C. at 36, 591 S.E.2d at 893 (quotation omitted). “Although the meaning of ‘privity’ has proven to be elusive, and there is no definition of the word . . . which can be applied in all cases, the prevailing definition in our cases, at least in the context of res judicataf,] ... is that privity denotes a mutual or successive relationship to the same rights of property.” Id. (quotation omitted). “In determining whether such a privity relation exists, courts will look beyond the nominal party whose name appears on the record as plaintiff and consider the legal questions raised as they may affect the real party or parties in interest.” Id.
The mere fact that one is a shareholder or officer of a corporation is not sufficient to establish privity for purposes of res judicata between the shareholder or officer and the corporation. Troy Lumber Co. v. Hunt, 251 N.C. 624, 627, 112 S.E.2d 132, 135 (1960).
However, there is an exception to the general rule requiring identity of parties:
*9A person who is not a party but who controls an action, individually or in cooperation with others, is bound by the adjudications of litigated matters as if he were a party if he has a proprietary interest or financial interest in the judgment or in the determination of a question of fact or a question of law with reference to the same subject matter, or transactions; if the other party has notice of his participation, the other party is equally bound.
Thompson v. Lassiter, 246 N.C. 34, 39, 97 S.E.2d 492, 496 (1957) (emphasis in original); see also Smoky Mountain Enterprises, Inc. v. Rose, 283 N.C. 373, 196 S.E.2d 189 (1973). Smoky Mountain Enterprises and Troy Lumber Co. address this exception in the context of corporations. In both Smoky Mountain Enterprises and Troy Lumber Co., the North Carolina Supreme Court placed emphasis on the shareholders of the corporations in determining whether an individual had “control” for purposes of applying the Lassiter exception to the rule of privity. Smoky Mountain Enterprises, Inc., 283 N.C. at 377, 196 S.E.2d at 192 (applying the exception in part because the individual was the president and owned all the stock of the corporate party); Troy Lumber Co., 251 N.C. at 628, 112 S.E.2d at 136 (declining to apply the exception in part because “[the corporation] has other shareholders than [the individual]”).
In the present case, the parties to the original lawsuit (File # 08 CVS 11281) were Peabody’s Home Improvements, Inc., Williams, Crystal Williams, and Platinum Lions Group, LLC. The parties to the present lawsuit (File # 10 CVS 2682) are Williams, WHF, Peabody, and Peabody’s Home Improvements, Inc. Both Peabody and WHF are new parties in the present lawsuit.2 Although evidence of record tends to show that Williams is the chief operating officer of WHF, this fact alone is insufficient to create privity between WHF and Williams. See Troy Lumber Co., 251 N.C. at 627, 112 S.E.2d at 135 (holding, “[t]he admission that F. L. Taylor is the controlling stockholder of Troy Lumber Company, is chairman of its board of directors, [is] President, and has complete charge of its operations and business, is insufficient to establish identity or privity between him and the corporation for the purpose of res judicata"). Likewise, the evidence surrounding Peabody’s roles in ownership and management of Peabody’s Home Improvements, Inc., is insufficient to create privity between Peabody *10and Peabody’s Home Improvements, Inc. Id. Therefore, we must determine whether the Lassiter exception to the rule requiring privity of identities applies to Peabody and Peabody’s Home Improvements, Inc., and to Williams and WHF.
a: Peabody and Peabody’s Home Improvements, Inc.
We first consider Peabody’s “control” of the original lawsuit and the present lawsuit, which is the threshold requirement of the exception to the rule requiring privity of identities. See Lassiter, 246 N.C. 34, 39, 97 S.E.2d 492, 496 (stating, “[a] person who is not a party but who controls an action, individually or in cooperation with others ...”) (emphasis added). Williams’ affidavit provides uncontroverted evidence that Peabody’s Home Improvements, Inc., is “solely operated by Anittie Peabody”; is “without real directors or shareholders”; and is “the alter ego of Anittie Peabody.” We believe this is sufficient to satisfy the control element of the Lassiter exception to the rule requiring privity. See Smoky Mountain Enterprises, Inc., 283 N.C. 373, 196 S.E.2d 189.
We next address the second requirement of the Lassiter exception, whether Peabody “has a proprietary interest or financial interest in the judgment!-]” Lassiter, 246 N.C. at 39, 97 S.E.2d at 496. Peabody’s Home Improvements, Inc., owned the four properties central to both the original and present lawsuits prior to the properties being purportedly conveyed to Platinum Lions Group, LLC, by Williams. There fore, the corporate party, Peabody’s Home Improvements, Inc., has a financial interest in the judgment. Because the evidence shows Peabody’s “control” of the corporate party, Peabody, individually, also has a financial interest in the judgment.
We finally address the third requirement of the Lassiter exception, whether Peabody has an interest “in the determination of a question of fact or a question of law with reference to the same subject matter, or transactions!.]” Lassiter, 246 N.C. at 39, 97 S.E.2d at 496. Because this is a dispute regarding four properties, and because Peabody’s Home Improvements, Inc., alleged in the original lawsuit the deeds conveying title were “deceptively and fraudulently executed],]” we believe Peabody and Peabody’s Home Improvements, Inc., have an interest in the determination of questions of law and fact in this case.
Because the foregoing evidence supports the requirements set forth in Lassiter for application of the exception to the rule requiring privity, we conclude the Lassiter exception applies to Peabody and *11Peabody’s Home Improvements, Inc. Therefore, assuming arguendo the Lassiter exception also applies to Williams and WHF, the identity of parties requirement is met, such that the trial court did not err in concluding the doctrine of res judicata operated to estop Plaintiffs’ action against Defendants. We must next determine whether the Lassiter exception, in fact, applies to Williams and WHF.
b: Williams, individually
Regardless of whether there is evidence of control to support the Lassiter exception as to WHF, Williams was a party to the original lawsuit and also a party to the present lawsuit. Satisfying the Lassiter exception to the rule requiring privity is not necessary to our determination of whether res judicata applies to Williams, individually. Because Williams was a party to both lawsuits, and because the evidence supports application of the Lassiter exception to Peabody and Peabody’s Home Improvements, Inc., the identity of parties requirement for application of res judicata to Williams’ lawsuit against Defendants in the present case is met. Frinzi, 344 N.C. at 414, 474 S.E.2d at 128 (“[B]oth the party asserting res judicata and the party against whom res judicata is asserted [must be] either parties or stand in privity with parties” to the original action”) (Emphasis added). Res judicata thus applies to Williams’ lawsuit against Defendants, and the trial court did not err by dismissing his lawsuit pursuant to the doctrine of res judicata. We affirm this portion of the trial court’s order.
c: Williams and WHF
We must next determine whether the Lassiter exception applies to WHF. We first consider Williams’ “control” of the original lawsuit and the present lawsuit, which is the threshold requirement of the exception to the rule requiring privity of identities. See Lassiter, 246 N.C. 34, 39, 97 S.E.2d 492, 496.
We believe Smoky Mountain Enterprises, Inc., 283 N.C. 373, 196 S.E.2d 189, is instructive in this case. In Smoky Mountain Enterprises, Inc., W.F. Burbank was the president and sole stockholder of Smoky Mountain Enterprises, Inc. Id. at 374, 196 S.E.2d at 190. Burbank and Jesse Rose signed a paper writing purporting to be a sales contract, which provided for the sale of all the assets of Smoky Mountain Enterprises, Inc. Burbank’s signature on the contract did not denote his corporate capacity and was not attested to by any other officer of Smoky Mountain Enterprises, Inc. Id. On 27 February 1970, Burbank individually instituted an action against the *12defendant, Rose, for breach of the contract. The trial court granted the defendant’s motion for summary judgment and dismissed that action with prejudice. Id. at 375, 196 S.E.2d at 191. On 7 October 1971, Smoky Mountain Enterprises, Inc., as the plaintiff, filed a complaint against Rose, alleging the same breach of contract. The North Carolina Supreme Court held the second suit was barred by the doctrine of res judicata. Id. at 378, 196 S.E.2d at 193.
In Smoky Mountain Enterprises, Inc., unlike the present case, Burbank’s control of the corporation and of both the original and subsequent lawsuits, was sufficiently supported by evidence. The Court concluded, “Burbank was personally in control of the action before Judge Martin in Superior Court and the present actionf;] [h]e had the same proprietary interest or financial interest in the judgment in both cases, and was equally concerned with the determination of questions of fact or questions of law pertaining to the contract which was involved in both actions.” Id. at 377, 196 S.E.2d at 192. Burbank’s control of the original and subsequent actions was shown, in part, by evidence that Burbank was the president and owned all the stock of Smoky Mountain Enterprises, Inc. The Court emphasized Burbank’s testimony: “On June 26, 1969, I was President of Smoky Mountain Enterprises, Inc., a corporation in which I owned all the stock.” Id. at 376, 196 S.E.2d at 192. The Court also emphasized the fact that central to both the original and subsequent lawsuit was a contract between Smoky Mountain Enterprises, Inc., and the defendant, which was signed by Burbank. The Court held that res judicata required that “Smoky Mountain Enterprises, Inc., is bound by the judgment of [the previous action][,]” which was instituted by Burbank, individually. Id. at 378, 196 S.E.2d at 192.
In the present case, the only evidence of record pertaining to Williams’ control of the original and present lawsuits, particularly the action by WHF against Defendants, is that Williams is the chief operating officer of WHF. There is no evidence of record that Williams is the sole or controlling shareholder of WHF, such that Williams was in control of WHF, and thereby, in control of WHF’s action against Defendants. The record is also silent on the question of whether there are other shareholders of WHF. Unlike in Smoky Mountain Enterprises, Inc. where the issue of control was clear, the evidence in this case shows, at most, that Williams was WHF’s chief operating officer. Troy Lumber Co. holds this alone is insufficient to create privity. We believe a logical extension of Smoky Mountain Enterprises, Inc. and Troy Lumber Co., is that this alone is insufficient to establish control *13for purposes of suspension of the rule of privity. Because there is no evidence regarding the shareholders or other officers of WHF of record, and because the sole evidence of control is that Williams is WHF’s chief operating officer, we believe this case is distinguishable from Smoky Mountain Enterprises, Inc. We believe the evidence in this case is insufficient to invoke the exception to the rule requiring privity as to WHF. If we concluded otherwise, the rule of privity for purposes of res judicata would be suspended in every case involving a chief operating officer of a corporation and the respective corporation, provided the remaining requirements in Lassiter, apart from “control,” were met.3
We next address the second requirement of the Lassiter exception to the rule requiring identity of parties, whether WHF “has a proprietary interest or financial interest in the judgment[.]” Lassiter, 246 N.C. at 39, 97 S.E.2d at 496; At the heart of both the original and present lawsuits lies a dispute regarding the four properties. In the original lawsuit, Peabody’s Home Improvements, Inc., alleged the deeds conveying title were “deceptively and fraudulently executed[.]” In the present lawsuit, Plaintiffs alleged “the funds of the Plaintiffs were the sole source of revenue for acquisition of the properties.” Moreover, the record contains a general warranty deed purporting to convey three of the four aforementioned properties from Crystal Williams to WHF. Based on the foregoing, we conclude WHF has a financial interest in the judgment.
We finally address the third requirement of the Lassiter exception, whether WHF has an interest “in the determination of a question of fact or a question of law with reference to the same subject matter, or transactions[.]” Lassiter, 246 N.C. at 39, 97 S.E.2d at 496. Again, because this is a dispute regarding the four properties, because Plaintiffs alleged that Plaintiffs’ funds “were the sole source of revenue for acquisition of the propertiesf,]” and because three of the properties were purportedly conveyed to WHF, we conclude WHF has an interest in the determination of questions of fact and law in reference to the subject matter in this case.
*14While the evidence supports the second and third requirements set forth in Lassiter — that WHF has a “financial interest” and an interest in the “determination of a question of fact or a question of law with reference to the same subject matter” — the evidence is insufficient to support the control requirement of the Lassiter exception to the rule requiring privity. Therefore, we must conclude the Lassiter exception cannot apply to WHF. Based on the foregoing, we conclude there is a genuine issue as to whether the exception to the rule of privity applies to WHF because the evidence in this case is insufficient to satisfy the requirement of control. Therefore, we further conclude the trial court erred by granting summary judgment barring WHF’s complaint on grounds of res judicata.
The dissenting opinion places strong emphasis on this Court’s opinion in Cline v. McCullen, 148 N.C. App. 147, 557 S.E.2d 588 (2001), in its determination that the identity of parties requirement is met with regard to WHF and Williams. We believe Cline is neither contrary to nor concordant with our holding on the issue of identity of parties in the present case: Cline is simply inapplicable because the opinion in Cline does not involve corporations, and the Cline Court does not apply the Lassiter exception to the rule requiring privity of parties.
Ill: Conclusion
In summary, we conclude that the doctrine of collateral estoppel does not apply to the present case, and the trial court erred by concluding Plaintiffs’ action was barred by collateral estoppel. We further conclude the trial court did not err in applying the doctrine of res judicata to dismiss Williams’ lawsuit against Defendants. However, in considering the application of res judicata to WHF’s lawsuit against Defendants — particularly, the requirement of identity of parties — we cannot presume facts not in the record regarding Williams’ control of the original and present lawsuits. We believe these facts are necessary in light of the holdings in Smoky Mountain Enterprises and Troy Lumber Co. As the evidence at trial was inadequate for the trial court to conclude the doctrine of res judicata applied to bar WHF’s action, we conclude the trial court erred by doing so. We reverse this portion of the trial court’s order on summary judgment and remand4 *15this case to the trial court to determine whether Williams had control of WHF and its action against Defendants.5
REVERSED and REMANDED.
Judge CALABRIA concurs. Judge ERVIN concurs in part, dissents in part by separate opinion.. But see Thomas M. McInnis & Associates, Inc. v. Hall, 318 N.C. 421, 432-34, 349 S.E.2d 552, 559-60 (1986) (stating, “[t]he modern trend in both federal and state courts is to abandon the requirement of mutuality for collateral estoppel, subject to certain exceptions, as long as the party to be collaterally estopped had a full and fair opportunity to litigate the issue in the earlier action[,]” and holding, “we see no good reason for continuing to require mutuality of estoppel in cases like this case”).
. We note that both Crystal Williams and Platinum Lions Group, LLC, were parties to the original lawsuit but not to the present lawsuit. Their absence in the present case is immaterial, as they are neither a “party asserting res judicata” nor a “party against whom res judicata is asserted].]” Frinzi, 344 N.C. at 414, 474 S.E.2d at 128.
. By comparison, although not authoritative in the context of res judicata, the definition of the element of control in the instrumentality rule for purposes of piercing the corporate veil offers some instruction on this point. It requires the following: “Control, not mere majority or complete stock control, but complete domination, not only of finances, but of policy and business practices in respect to the transaction attacked so that the corporate entity as to this transaction had at the time no separate mind, will, or existence of its own.” Glenn v.

Schultz, 364 N.C. 90, 96, 691 S.E.2d 701, 706 (2010) (affirming this Court’s reversal of an order on summary judgment, stating that “a factual inquiry must be conducted to determine whether [the attorney] also represented sellers during the closing process],]” and holding that “we remand this case to the trial court to determine if an attorney-client relationship existed between sellers and [the attorney]”).
