OPINION
This case addresses whether the Virginia doctrine of collateral estoppel applies to allegations of legal malpractice. Alan D. Weinberger (“Weinberger”) and ASCII Group, Inc. (“ASCII”) sued their former lawyer, Stefan F. Tucker (“Tucker”), for fraud, breach of fiduciary duty, and professional negligence. For the reasons outlined below, we affirm the district court’s finding that collateral estoppel bars this lawsuit.
I.
Weinberger is the founder and CEO of ASCII. TechnologyNet, Inc. (“TechNet”) is a separate corporation, incorporated by Weinberger and others. ASCII retained the Tucker, Flyer, & Lewis law firm in May 1998. At that firm, Tucker was primarily responsible for representing ASCII. When he moved to Venable, Baetjer & Howard, LLP (‘Venable”) in 2000, Weinberger and ASCII went with him as clients.
Concurrently, Tucker and Venable represented technology investor Lev Volftsun (“Volftsun”). In Fall 2000, at a party at his house, Tucker introduced Weinberger and Volftsun. At that time, TechNet was seeking investors. In January 2001, Tucker arranged a meeting between Wein-berger and Volftsun at Venable’s office, during which Volftsun agreed to loan TechNet $250,000 and to become a member of the Board. On January 9, 2001, Tucker helped negotiate a bridge note and other terms of Volftsun’s loan to TechNet. In conjunction with the January meeting, Tucker sent both parties a waiver letter, stating that with regard to the loan Tucker had only represented Voftsun’s interests. 1 The letter, dated January 17, 2001, was intended to apply retroactively to the January 9 meeting.
*490 In Spring 2001, TechNet began to decline and Weinberger sought to protect his estate, as well as ASCII, from TechNet creditors. Weinberger claims he met with Tucker at Venable, seeking his advice, and that Tucker advised him to create a separate holding company. 2 In the process of creating the holding company, ASCII Technology Holdings, Inc. (“ATH”), Wein-berger and ASCII sought the assistance of another attorney, Paul Rogers (“Rogers”) of Covington & Burling. Rogers presented the proposal to the TechNet Board on July 13, 2001. In Summer 2001, Wein-berger held discussions with board members, including Volftsun, concerning loans to TechNet. Volftsun agreed to loan TechNet an additional $150,000. ASCII was to guarantee both Volftsun’s January 2001 and July 2001 loans. Weinberger alleges that he sent Tucker a letter that stated:
as I have told you and Lev many times, that any language of any possible guarantee of ASCII lasts only until, the holding company is agreed to by vote of stockholders. I would never risk 17 years of my life’s work and the livelihood of long term employees and put in jeopardy ASCII, but I am enabling 150 investors of TechnologyNet, Inc., many who I know personally, to obtain some return. As my lawyer, this is very important to me for you to understand.
(J.A. 148.) 3 In September 2001, a memo from ATH was sent to all the TechNet and ASCII shareholders offering to exchange their shares for shares in ATH. According to Weinberger, all the shareholders but Volftsun complied. Weinberger attempted to convince Volftsun to convert his debt into equity, but ultimately failed.
A. Volftsun v. ASCII Group (ASCII I)
Volftsun, represented by Venable, sued ASCII, ATH, and TechNet (collectively “ASCII”) in the Eastern District of Virginia to enforce the guarantee (“the underlying case”). ASCII filed a motion to disqualify counsel, alleging a conflict of interest. Volftsun filed a brief in opposition to the motion to disqualify. The court held a hearing on the motion and denied the motion to disqualify, based on the January 2001 waiver letter. Ultimately, the court found the guarantee binding on ASCII and entered a final judgment in favor of Volftsun.
B. Weinberger v. Tucker (ASCII II)
On July 1, 2004, Weinberger and ASCII (collectively “Weinberger” with respect to this action) filed a suit against Tucker for fraud, breach of fiduciary duty, and professional negligence. Tucker moved to dismiss, based on collateral estoppel. On September 29, 2005, the United States District Court for the District of Columbia transferred the case to the Eastern District of Virginia (“district court”) and denied Tucker’s motion without prejudice for mootness. Following the transfer, Tucker filed a renewed motion to dismiss, also based on collateral estoppel. Weinberger filed a response to the renewed motion to dismiss. The district court held a hearing on Tucker’s motion, dismissed Wein-berger’s claim based on collateral estoppel, and entered a judgment for Tucker on November 9, 2006. Weinberger appeals to this Court.
II.
As all parties are in agreement as to the proper standard, we review the district court’s decision de novo.
*491
Collateral estoppel, or issue preclusion, provides that once a court of competent jurisdiction actually and necessarily determines an issue, that determination remains conclusive in subsequent suits, based on a different cause of action but involving the same parties, or privies, to the previous litigation.
See Montana v. United States,
Both parties agree that, as this is a diversity jurisdiction case in a Virginia federal district court, Virginia collateral es-toppel law applies. In Virginia, collateral estoppel requires: (1) the parties to the two proceedings, or their privies, be the same; (2) the factual issue sought to be litigated must have been actually litigated in the prior action and must have been essential to the prior judgment; and (3) the prior action must have resulted in a valid, final judgment against the party sought to be precluded in the present action.
In re Ansari,
Weinberger maintains that he is not es-topped from bringing his professional negligence, fraud, and breach of fiduciary duty claims, as Volftsun’s failure to convert his debt into equity and the validity of the guarantee were the central issues in AS CII I. Tucker counters that the denial of the motion to disqualify and the upholding of the guarantee fundamentally resolve the disputes at issue in the case. We agree.
A.
The first element of collateral estoppel requires that the parties, or their privies, be parties to the underlying case. Wein-berger argues that the parties are not the same: in the first action Volftsun sued ASCII, TechNet, and ATH, and in this action, Weinberger and ASCII sued Tucker. Tucker responds that even though Tucker and Weinberger were not parties to the original proceedings, privity exists between Weinberger, as the founder and CEO of ASCII, and the company itself, as well as between Volftsun and Tucker, as his lawyer.
“Under both Fourth Circuit and Virginia decisions, the test for privity is [ ] the same: whether the interests of one party are so identified with the interests of another that representation by one party is representation of the other’s legal right.”
Londono-Rivera v. Virginia,
There is no single fixed definition of privity for purposes of res judicata. Whether privity exists is determined on *492 a case by case examination of the relationship and interests of the parties. The touchstone of privity for purposes of res judicata is that a party’s interest is so identical with another that representation by one party is representation of the other’s legal right.
We now conduct an individualized examination of whether collateral estoppel properly applies to each of the parties in the present action: ASCII, Weinberger, and Tucker.
1.
As ASCII was a party in the underlying case and is also a party here, collateral estoppel clearly can apply.
2.
Weinberger argues that his interests are distinct from ASCII’s in the underlying action. He maintains that he was personally represented by Tucker and is bringing the action not only on behalf of ASCII but on behalf of himself in his individual capacity. Tucker responds that the damages Weinberger alleges stem from his shared economic identity with ASCII. He is correct.
As the chairman of both ASCII and the holding company and as the owner of a majority of ASCII’s stock, Weinberger is the real party of interest when ASCII incurs damages. Weinberger’s interests are so in line with those of ASCII that representation by ASCII in the underlying action effectively represented Wein-berger’s legal rights in the present case. 4 We, therefore, hold that there is privity between Weinberger and ASCII.
3.
According to Weinberger, Tucker is not in privity with Volftsun. Wein-berger argues that the attorney-client relationship is not sufficient to establish privity. Furthermore, Weinberger points out that Tucker did not represent Volftsun in ASCII I and that Tucker never testified or presented any evidence that he had a personal stake in the ASCII I litigation. Tucker responds that he and Volftsun shared identical interests with respect to the motion to disqualify Venable and the validity of the guarantee. Tucker argues that he had a particularly strong interest, as the enforcement of the guarantee rested on his conduct and he faced the possibility of a legal malpractice suit by Volftsun had the defendants in ASCII I succeeded in their defenses that the guarantee had expired or that the guarantee was fraudulently induced. We again agree with Tucker.
The concept of privity requires an alignment of interests and not an exact identity of parties. In
Nash County Board of Education v. Biltmore Co.,
“Privity states no reason for including or excluding one from the estoppel of a judgment. It is merely a word used to say that the relationship between the one who is a party on the record and another is close enough to include that other within the res judicata.”
Thus, privity centers on the closeness of the relationship in question. Courts have
*493
held that the attorney-client relationship itself establishes privity.
See, e.g., Plotner v. AT & T Corp.,
B.
For collateral estoppel to apply, the factual issues in the subsequent case must have been essential to and actually litigated in the underlying case.
1.
In this case, Weinberger sued Tucker for professional negligence, breach of fiduciary duty, and fraud. Weinberger explains that while the enforcement of the guarantee was at issue in the first litigation, this action deals specifically with Tucker’s misconduct. Tucker argues that the judge’s findings in ASCII I negate the elements of Weinberger’s claims against Tucker.
The district court in ASCII I resolved issues essential to the present case. For example, in honoring the waiver letter and denying the motion to disqualify Venable, the court rejected ASCII’s, and therefore Weinberger’s, argument that Venable was simultaneously representing ASCII, Wein-berger, and Volftsun. In so doing, the district court found that, as of the waiver letter, ASCII, and thus ASCII’s privy Weinberger, enjoyed no attorney-client relationship with Tucker or other Venable lawyers with respect to the guarantee. If Tucker was not Weinberger’s lawyer, Weinberger could not sue Tucker for legal malpractice or breach of fiduciary duty, as Tucker’s only professional obligations laid with Volftsun. Similarly, the district court’s rejection of ASCII’s fraudulent inducement argument and upholding of the guarantee’s validity undermine Wein-berger’s fraud claim. Because the central disputes of this case flow from the waiver agreement and Tucker’s conduct with regard to the validity of the guarantee, we hold that the issues resolved in ASCII I *494 are essential to Weinberger’s current claims.
2.
Weinberger asserts that the denial of the motion to disqualify did not constitute a full and fair review. Tucker, however, contends that the. issue is not precluded merely based on the motion to disqualify, but also on the finding on the merits that the guarantee was enforceable and was not fraudulently induced, the finding that the parties were separately represented with respect to the guarantee, and the finding that the guarantee was negotiated at arm’s length.
In
TransDulles,
C.
Additionally, the prior judgment must have been final and valid. Wein-berger maintains that the ruling on the motion to disqualify is not a final judgment subject to appeal because ASCII appealed in July 2003 and, due to a lack of funds, entered settlement negotiations with Volft-sun in August 2003. This argument is not compelling. According to the Virginia Supreme Court, “a judgment is not final for the purposes of
res judicata
or collateral estoppel when it is being appealed or when the time limits fixed for perfecting the appeal have not expired.”
Faison v. Hudson,
D.
Under the principle of mutuality, a litigant may not invoke a preclusive judgment if he would not have been bound by the opposite result.
Rawlings v. Lopez,
In
Angstadt v. Atlantic Mutual Insurance Co.,
III.
Weinberger cannot prevail on his claims without directly contradicting the court’s findings in ASCII I. We hold that Virginia’s doctrine of collateral estoppel bars any attempt by Weinberger to repackage the claims rejected in the underlying case as claims against Tucker. Accordingly, we affirm the district court’s dismissal. 6
AFFIRMED
Notes
. The letter, addressed to "Alan and Lev” stated:
As we discussed — during separate telephone conversations that I have had with Alan (and in some of those, Robert Freer) and with Lev, and in the conference which we all had at the Venable Tyson’s [sic] office on January 9, 2001 — Venable and in most circumstances I personally have represented (i) Lev and Margo Volftsun in connection with a number of personal matters, including estate planning; (ii) Alan and Lauren Weinberger in connection with a number of personal matters, including estate planning and Alan's contract with TechnologyNet, Inc.; (iii) The ASCII Group, Inc. in connection with the negotiation of its relationship with TechnologyNet, Inc., and the agreements resulting therefrom; and (iv) TechnologyNet, Inc. in connection with some of the issues related to its disassociation with i2. In other words, at one point or another, Venable has represented all of you in connection with one or more matters.
Notwithstanding the foregoing, it is recognized by Lev, Alan, TechnologyNet, Inc. and The ASCII Group, Inc. that, with regard to Lev's $250,000 loan to Technolo-gyNet, Inc., as evidenced by Bridge Note No. 7, and Lev's acquisition of 175,000 options to acquire TechnologyNet, Inc. stock, Venable, and I personally, have represented only Lev. My role, in large measure, was to review the documentation, obtain the appropriate back-up documents and agreements, and advise Lev of the risks inherent in such a loan. I performed that role prior to and during our meeting on January 9, 2001.
As a condition precedent to my undertaking the foregoing on behalf of Lev, Lev, [sic] Alan, TechnologyNet, Inc. and The ASCII Group, Inc. agreed to waive any actual or potential conflicts of interest. I am sending this letter to you to reflect the same, and I am requesting that you sign a copy of the letter and return it to me.
(J.A. 96-97.)
. However, at a deposition in Volftsun v. The ASCII Group, Tucker maintained he recalled no such meeting. (J.A. 969-71.)
. Tucker testified that he never received the letter. (J.A. 376.)
. Had Weinberger brought a legal malpractice action against Tucker based on issues stemming from Tucker's conduct in handling Weinberger's estate or tax planning, ASCII would not have adequately represented Wein-berger’s interests in the previous action. At oral argument, however, Weinberger conceded that all the claims in the present action flow from Tucker’s actions surrounding the guarantee.
. Again, had Weinberger alleged claims not flowing from the guarantee, Tucker and Volft-sun would not have been privies with respect to those claims, as Volftsun could not have represented Tucker's interest.
. On May 21, 2007, Tucker filed a motion for leave to file a surreply with a proposed surre-ply. Weinberger opposed. We deferred consideration until oral argument. We now grant Tucker’s motion and accept his surre-piy-
