    AMBRO, Circuit Judge
    This is a twist on a classic corporate divorce story. It
    6
    begins much as Judge Richard Cudahy’s “classic corporate love
    story”: “Company A meets Company B. They are attracted to
    each other and after a brief courtship, they merge.” GSC
    Partners CDO Fund v. Washington, 
    368 F.3d 228
    , 232 (3d Cir.
    2004). Sadly, it does not last. Not long after Company A
    acquires Company B, they start taking risks together, some of
    which go terribly wrong. After only a year or so, Company B
    is steeped in debt, and, not surprisingly, Company A begins to
    “los[e] that lovin’ feelin’.”1 It leaves Company B, explaining
    that it simply must do so in order to save itself. Jilted and out of
    money, Company B promptly turns to that shelter for abandoned
    corporations, the bankruptcy system.
    In bankruptcy, Company B’s children (subsidiaries), also
    in the shelter of bankruptcy, become indignant, and they sue
    Company A for all manner of ills relating to the break-up. Here,
    we deal not with the merits of the action, but with a pre-trial
    dispute over corporate documents. Everyone agrees that the
    attorney-client privilege protects these documents against third
    parties. The wrinkle is that they were produced by and in
    communication with attorneys who represented the entire
    corporate family back when they all got along.
    The question, then, is whether Company A may assert the
    1
    Righteous Brothers, You’ve Lost That Lovin Feelin, on YOU’VE
    LOST THAT LOVIN FEELIN (Phillies 1965).
    7
    privilege against its former family members. Because we
    conclude that the District Court’s factual findings do not support
    setting aside the parent company’s privilege in this case, we
    vacate its order compelling production and remand for further
    proceedings.
    I.         Facts and Procedural History
    A.     The Parties and Underlying Causes of Action
    This action began with a complaint brought in a Chapter
    11 bankruptcy case. The debtors (“Debtors”) are the wholly
    owned United States subsidiaries of a Canadian
    telecommunications company formerly known as Teleglobe,
    Inc. (“Teleglobe”). Teleglobe and the Debtors are undergoing
    reorganization in Ontario in accordance with the Canadian
    Companies’ Creditors Arrangement Act (the “Arrangement
    Act”), a form of bankruptcy protection similar to Chapter 11. In
    addition, the Debtors (but not Teleglobe), all but one2 of which
    are Delaware corporations, are simultaneously undergoing
    Chapter 11 reorganization in the District of Delaware. Until
    recently, Teleglobe was a wholly owned subsidiary of Bell
    Canada Enterprises, Inc. (“BCE”), Canada’s largest
    2
    One is a Puerto Rico corporation.
    8
    telecommunications company.3
    In 2000, BCE, which had previously owned a 23%
    minority stake in Teleglobe, purchased all its remaining shares
    (directly and indirectly through subsidiaries), thus taking control
    of the company. According to the Debtors, in late 2000 BCE
    directed Teleglobe to accelerate the development of a fiberoptic
    network called GlobeSystem. BCE pledged its financial support
    to the project and caused Teleglobe and its subsidiaries (the
    Debtors) to borrow some $2.4 billion from banks and
    bondholders. The bond debt was guaranteed by one of the
    Debtors. Teleglobe exhausted its funding in 2001, and in
    November of that year BCE approved an additional $850
    million equity infusion for Teleglobe and its subsidiaries. These
    monies were to be disbursed at the sole discretion of Jean
    Monty, then Chairman and CEO of BCE as well as Chairman
    and CEO of Teleglobe. BCE announced its intention to
    continue funding Teleglobe in December 2001.
    About this time BCE began working on what personnel
    referred to as Project X—a comprehensive reassessment of
    BCE’s plans for Teleglobe. Lurking in the background was
    3
    As a result of the Canadian reorganization process,
    Teleglobe, now known as VSNL International Canada, operates
    as a subsidiary of VSNL, a telecommunications company
    organized in India, which itself is owned by the Tata Group, an
    Indian conglomerate.
    9
    BCE’s declining confidence in GlobeSystem’s ultimate
    potential.4 In the course of Project X, BCE considered a variety
    of options, including maintaining its funding in the hope that
    GlobeSystem would be profitable, restructuring Teleglobe in
    such a way that it could continue as a viable subsidiary, and
    simply cutting off funding (which would send Teleglobe and its
    subsidiaries into a liquidating bankruptcy). In early April 2001,
    BCE publicly announced that it was reassessing its funding of
    Teleglobe; just a few weeks later, it ceased its funding,
    effectively abandoning Teleglobe. GlobeSystem was not
    operational, and so Teleglobe had no means of paying back its
    multi-billion dollar debt. Consequently, within weeks Teleglobe
    and the Debtors filed for Arrangement Act relief in Canada, and
    the Debtors also filed for Chapter 11 relief in Delaware.
    4
    As stock market junkies may recall, Teleglobe was but one
    of many victims of the “telecom meltdown” of 2000–2001. In
    the late 1990s deregulation in the United States and Europe
    touched off a rush to build new telecom infrastructure. Like so
    many other companies in that period, Teleglobe spent much debt
    capital to build fiberoptic lines around the world. Because of
    the ensuing glut of infrastructure, prices tumbled, and Teleglobe,
    along with a host of other over-leveraged telecom firms, went
    bankrupt. See, e.g., Peter Elstrom & Heather Timmons,
    Telecom Meltdown, BUSINESSWEEK, Apr. 23, 2001, at 100;
    Gordon Pitts, When Friends Do Business with Each Other,
    GLOBE & MAIL (CANADA), Apr. 27, 2002, at B1.
    10
    For BCE’s role in funding and then abandoning the
    GlobeSystem project, the Debtors sued it in this adversary
    proceeding.5 They assert several causes of action, including
    breach of contract, breach of fiduciary duties, estoppel, and
    misrepresentation (whether fraudulent or negligent). All claims
    relate to the manner in which BCE ceased funding Teleglobe,
    the Debtors’ corporate parent. Debtors’ theme is that BCE
    reneged on binding commitments to fund Teleglobe and
    fraudulently or negligently induced Teleglobe and the Debtors
    to continue incurring debt in reliance on those commitments,
    thus harming, inter alia, Teleglobe, the Debtors, and the
    Debtors’ creditors. Moreover, they allege that BCE, as the
    controlling shareholder of Teleglobe and the Debtors while
    those entities were insolvent, breached its fiduciary duties to the
    Debtors.
    B.    The Privilege Dispute
    In the District of Delaware Bankruptcy Court, the
    Debtors and the Creditors Committee began exploring through
    5
    At one time the committee of unsecured creditors (the
    “Creditors’ Committee”), appointed under 
    11 U.S.C. § 1102
    (a)(1), was also a plaintiff; it, however, has been
    dissolved with the confirmation of the Debtors’ plan of
    reorganization.
    11
    Rule 20046 discovery the possibility of suing BCE for the
    manner in which it abandoned Teleglobe and the Debtors. In
    response to discovery requests, BCE marked 98 documents as
    protected by a “common interest privilege.”7 When the creditors
    moved to compel production, BCE responded that the
    documents were privileged because “BCE attorneys consulted
    with attorneys, officers, or employees of Teleglobe, Inc. or its
    subsidiaries to discuss or provide legal advice in matters where
    BCE and Teleglobe, Inc. (or its subsidiaries) shared a common
    legal interest.” App. at A01110. BCE further stated that the
    “privilege will continue to exist until the Debtors file a litigation
    against BCE.” 
    Id.
    At a hearing in the Bankruptcy Court, BCE—in keeping
    with the theme of its argument—agreed to produce (even
    without the filing of a suit) the “common interest” documents to
    the Debtors, seemingly agreeing that they fell within the scope
    of their shared interest, and the Bankruptcy Court entered an
    order to that effect. BCE did not specifically admit that it was
    required to produce the documents; it merely agreed to do so.
    It continued to maintain, however, that the rest of the documents
    6
    Federal Rule of Bankruptcy Procedure 2004 allows parties
    with an interest in the bankruptcy estate to conduct discovery
    into matters affecting the estate.
    7
    We assume that BCE meant to invoke the joint-client
    privilege, rather than the common-interest privilege. We
    explain the difference in Part IV.C, infra.
    12
    designated as privileged represented advice provided solely to
    it and were not part of any joint representation with Teleglobe
    or the Debtors. It is unclear from the record exactly what the 98
    “common interest” documents contained that BCE agreed to
    produce, but the privilege logs reflect that they primarily
    consisted of documents created by BCE’s in-house counsel on
    the subject of Teleglobe’s financing and restructuring. At the
    same time, the privilege log (exclusive of the 98 “common
    interest” documents) lists many other documents reflecting legal
    advice on Project X matters that BCE claimed—then and
    now—were intended as advice solely to it and not as part of any
    joint representation. See generally App. at A00967–A01091.
    Once the Debtors and Creditors’ Committee filed their
    suit against BCE, the District Court withdrew its automatic
    reference to the Bankruptcy Court and began handling the suit
    itself. The District Court held an initial discovery conference at
    which BCE reasserted that it had produced all of the documents
    that it thought were generated as a result of a
    BCE/Teleglobe/Debtors joint representation and that the
    documents it was withholding reflected advice provided to and
    intended solely for BCE. App. at A00264–65. The Debtors did
    not press the joint representation/common interest point at that
    time, nor did they argue for a broader scope of the joint
    representation/common interest than BCE had admitted; rather,
    they focused on an extension of the “conflicted fiduciary” line
    13
    of cases, see Part VI.A, infra.8 App. at A00262–63.
    The District Court ended up referring the discovery
    dispute to a Special Master—C.J. Seitz, Jr., Esquire. In its
    initial written response to the Debtors’ motion to compel
    production before the Special Master, BCE stated that it had, in
    response to the Bankruptcy Court’s Rule 2004 order, “produced
    to the Debtors all the documents that were protected by a
    common interest.” App. at A0197. BCE further stated that it
    had reviewed all of the documents on the privilege log and that
    the only documents that remained designated as privileged were
    those “reflect[ing] the provision of legal work solely to BCE.”
    
    Id.
    8
    In brief, these cases provide that when a corporation’s
    shareholders attempt to bring a derivative suit on behalf of the
    corporation against its directors for breaching their fiduciary
    duties, the shareholders can invade the corporation’s privilege
    upon showing “good cause.” Garner v. Wolfinbarger, 
    430 F.2d 1093
    , 1103–04 (5th Cir. 1970). A more expansive view of the
    rule is phrased thus: “where a corporation seeks advice from
    legal counsel, and the information relates to the subject of a later
    suit by a minority shareholder in the corporation, the corporation
    is not entitled to claim the [lawyer-client] privilege as against its
    own shareholder, absent some special cause.” Valente v.
    PepsiCo, Inc., 
    68 F.R.D. 361
    , 367 (D. Del. 1975). As detailed
    in Part VI.A, Delaware courts have followed Garner but
    declined broadly to apply Valente.
    14
    The Debtors then expanded their argument by contending
    that the scope of the joint representation was broader than BCE
    admitted. Specifically, they claimed that various attorneys
    represented all of the entities on the matters of BCE’s decision
    to cease funding Teleglobe and Teleglobe’s resulting
    restructuring. BCE, on the other hand, claimed that it retained
    its own attorneys to advise it on those matters. The Special
    Master found that the Debtors had not met their burden of
    proving an exception to the attorney-client privilege. The
    evidence, he concluded initially, merely showed that BCE’s in-
    house counsel represented Teleglobe and the Debtors
    occasionally; it did not show a broad joint representation as to
    the abandonment of Teleglobe. Recognizing, however, that the
    Debtors did not trust BCE’s representation that the documents
    marked as privileged reflected advice provided solely to BCE,
    the Special Master ordered a 50-document audit by his in
    camera review to ensure the accuracy of BCE’s representations.
    The Special Master also rejected the Debtors’ conflicted
    fiduciary argument, noting that the Delaware Court of Chancery
    has refused to adopt it in its broader form. Deutsch v. Cogan,
    
    580 A.2d 100
    , 105 (Del. Ch. 1990) (“Although neither the
    Garner nor Valente case is binding on this Court, Delaware
    courts have consistently followed Garner and declined to
    broadly apply Valente.”) (citations omitted). More importantly,
    the Special Master forestalled any further “conflicted fiduciary”-
    style argument by ruling that neither Teleglobe nor the Debtors’
    boards were conflicted in any sense because all of their duties
    15
    flowed back up to BCE (and not, as the Debtors argued, to their
    creditors). See Anadarko Petroleum Corp. v. Panhandle
    Eastern Corp., 
    545 A.2d 1171
    , 1174 (Del. 1988) (“[I]n a parent
    and wholly-owned subsidiary context, the directors of the
    subsidiary are obligated only to manage the affairs of the
    subsidiary in the best interests of the parent and its
    shareholders.”). The Special Master, however, did not make an
    express finding of fact on when the Debtors became insolvent
    (or entered the amorphous9 “zone of insolvency”), reasoning
    instead that there was no way to get from the Debtors’ directors
    owing fiduciary duties to creditors of the Debtors on one hand
    to BCE owing a duty to those creditors on the other.
    According to the Special Master, “[s]hortly after the
    Debtors made their selection of documents for in camera
    review, the wheels started coming off [BCE’s] privilege
    wagon.” App. at A0030. Before the review, BCE withdrew its
    privilege assertion for six of the 50 documents that the Debtors
    9
    A footnote from the Delaware Supreme Court’s latest
    opinion on a related issue explains that this “zone” is yet ill-
    defined: “In light of its ultimate ruling, the Court of Chancery
    did not attempt to set forth a precise definition of what
    constitutes the ‘zone of insolvency.’ Our holding in this opinion
    also makes it unnecessary to precisely define a ‘zone of
    insolvency.’” N. Am. Catholic Educ. Programming Found., Inc.
    v. Gheewalla, ___ A.2d ___, 
    2007 WL 1453705
    , at n.20 (Del.
    2007).
    16
    selected. Then, the Special Master determined that three of the
    documents did not involve the provision of legal advice at all,
    and three lent credence to the Debtors’ argument that BCE
    attorneys jointly represented BCE and Teleglobe on the issue of
    BCE’s abandonment. After the initial in camera review, BCE
    withdrew the privilege assertion for still more documents.
    Having reviewed 44 documents in camera, the Special
    Master issued a supplemental decision in which he concluded
    that BCE’s revised privilege claims and his review of documents
    in camera “raised serious questions about” the reliability of the
    privilege log, whether BCE attorneys jointly represented BCE
    and Teleglobe on the abandonment issue, whether the
    documents withheld reflected legal advice provided solely to
    BCE, and whether the documents withheld were in fact
    privileged. App. at A0031. He ordered BCE to review and
    revise the privilege log and to submit all purportedly privileged
    documents to him for in camera review.
    BCE culled its privilege log to just over 1,000
    documents. Then, between the submission of the revised
    privilege log and the submission of the actual documents, BCE
    withdrew the assertion of privilege for over 100 additional
    documents. BCE still wasn’t finished; while the in camera
    review proceeded, it withdrew its assertion of privilege in four
    separate letters to the Special Master, covering well over 100
    more documents.
    17
    One of the issues raised by the Debtors in supplemental
    briefing was BCE’s apparent over-designation of privileged
    documents. According to the Debtors, this was substantial
    enough to merit wholesale disclosure of the documents on
    BCE’s privilege log as a discovery sanction. The Special
    Master agreed that BCE “failed the audit in multiple
    ways—withdrawing documents before in camera review,
    claiming privilege over documents that did not reflect legal
    advice, and claiming privilege over documents where it
    appeared that BCE in-house attorneys and outside counsel
    jointly represented BCE, Teleglobe, or the Debtors on matters
    of common interest.”
    In his final decision, the Special Master declined to
    impose disclosure as a discovery sanction. But he nonetheless
    reversed himself and ordered the production of all of the
    documents on the privilege log. Having reviewed some 800
    documents in camera, he found that they “revealed a broad legal
    representation of both BCE and Teleglobe by BCE’s in-house
    attorneys relating to Teleglobe’s restructuring alternatives.”
    App. at A0047–48. He further found that all of the documents
    on the privilege log were disclosed to BCE’s in-house counsel,
    which made them discoverable because those attorneys were
    jointly representing Teleglobe and could not, therefore, withhold
    the documents from it. 
    Id.
     at A0055. He applied this reasoning
    even to documents produced by outside counsel hired only to
    18
    work for BCE.10
    The District Court affirmed the Special Master’s decision
    and ordered BCE to turn over to the Debtors all of the
    documents. BCE argued that the Special Master’s finding of a
    broad joint representation between it and Teleglobe was
    irrelevant because he had not found a joint representation
    between it and the Debtors. Unless the Debtors were a party to
    the joint representation, BCE argued, they could not invade its
    privilege. The Court rejected this argument on three grounds:
    (1) BCE made a binding agreement to disclose all
    communications generated as part of a BCE/Teleglobe joint
    representation, and so finding a joint representation between the
    two was all that was needed; (2) the Debtors, as wholly owned
    subsidiaries of Teleglobe, were parties to the joint representation
    as a matter of law, and (3) even the documents that fell outside
    of the joint representation (i.e., were produced by outside
    counsel) must be disclosed because they were shared with
    BCE’s in-house attorneys, who jointly represented Teleglobe.
    II.        Jurisdiction
    10
    Specifically, the Special Master concluded that the law
    firms Strikeman Elliot and Shearman & Sterling produced at
    least some documents for the sole benefit of BCE, but he
    ordered the production of those documents because they were
    shared with BCE’s in-house attorneys, who were jointly
    representing it and Teleglobe.
    19
    This is an appeal from an interlocutory order.
    Nevertheless, we have jurisdiction under the collateral order
    doctrine, which provides an exception to the finality requirement
    of 
    28 U.S.C. § 1291
    . Under it, an immediate appeal lies if the
    following elements are met: “(1) the order from which the
    appellant appeals conclusively determines the disputed question;
    (2) the order resolves an important issue that is completely
    separate from the merits of the dispute; and (3) the order is
    effectively unreviewable on appeal from a final judgment.” In
    re Ford Motor Co., 
    110 F.3d 954
    , 958 (3d Cir. 1997) (citing
    Rhone-Poulenc Rorer, Inc. v. Home Indem. Co., 
    32 F.3d 851
    ,
    860 (3d Cir. 1994)).
    Here, the first and third prongs are clearly met, as the
    District Court ordered the production of some 800 documents
    currently in dispute. See In re Ford Motor Co., 
    110 F.3d at 958
    (holding that the first prong is met when a district court orders
    the production of documents). Once documents are disclosed,
    any dispute over their privileged status is effectively moot and
    unreviewable, as the very purpose of the privilege is frustrated
    by compelled disclosure. 
    Id. at 963
     (“[T]he limited assurance
    that the protected material will not be disclosed at trial ‘will not
    suffice to ensure free and full communication by clients who do
    not rate highly a privilege that is operative only at the time of
    trial.’” (quoting Chase Manhattan Bank, N.A. v. Turner &
    Newall, PLC, 
    964 F.2d 159
    , 165 (2d Cir. 1992))).
    The only question, then, is whether the privilege issue is
    20
    sufficiently separate from the merits of the suit. It is, as we have
    no occasion to consider the issues that lie at the heart of the
    case: the existence, content, and alleged breach of any contract
    between BCE, Teleglobe, and/or the Debtors; the content and
    fraudulent or negligent nature of any representations made by
    BCE; and the alleged breach by BCE of fiduciary duties it
    purportedly owed to the Debtors. Rather, we concern ourselves
    with the extent to which BCE, Teleglobe, and the Debtors were
    jointly represented by counsel and the effect any joint
    representation has on BCE’s ability to shield documents from
    disclosure. In this context, we have little trouble concluding that
    we have jurisdiction over this appeal.
    III.   Choice of Law
    BCE argues that Canadian law should govern all aspects
    of this appeal; the Debtors, on the other hand, argue for
    Delaware law. As a federal court exercising jurisdiction over
    state-law claims, we apply the choice-of-law rules of Delaware,
    the forum state. Hammersmith v. TIG Ins. Co., 
    480 F.3d 220
    ,
    226 (3d Cir. 2007).
    “Delaware courts look to the Restatement (Second) of
    Conflict[s] of Laws for guidance in choice of law disputes.”
    Gloucester Holding Corp. v. U.S. Tape & Sticky Prods., LLC,
    
    832 A.2d 116
    , 124 (Del. Ch. 2003). Here, § 139 of the
    Restatement applies:
    21
    (1) Evidence that is not privileged under the local law of
    the state which has the most significant relationship with
    the communication will be admitted, even though it
    would be privileged under the local law of the forum,
    unless the admission of such evidence would be contrary
    to the strong public policy of the forum.
    (2) Evidence that is privileged under the local law of the
    state which has the most significant relationship with the
    communication but which is not privileged under the
    local law of the forum will be admitted unless there is
    some special reason why the forum policy favoring
    admission should not be given effect.
    RESTATEMENT (SECOND) OF CONFLICTS OF LAWS § 139 (1971).
    These provisions presuppose a conflict between the law
    of the forum state and the law of the state with the most
    significant relationship. This is because courts typically wade
    into choice-of-law determinations when those laws truly
    conflict. See Huber v. Taylor, 
    469 F.3d 67
    , 74 (3d Cir. 2006)
    (citing On Air Entm’t Corp. v. Nat’l Indem. Co., 
    210 F.3d 146
    ,
    149 (3d Cir. 2000)). While there are no reported Delaware cases
    on this point, we predict that Delaware would follow the
    practice of the federal system and most states, and decide a
    choice-of-law dispute only when the proffered legal regimes
    actually conflict on a relevant point.
    22
    BCE argues for Canadian law here, but concedes that it
    has found no relevant conflict of Canadian with Delaware law.11
    This undercuts BCE’s argument, particularly given that the
    Restatement favors the admission of evidence when the law of
    the forum state so requires; thus, if applying Canadian law will
    safeguard the privilege, it is BCE’s responsibility not only to
    highlight the legal conflict, but also to point to “some special
    reason” favoring protection. See RESTATEMENT (SECOND) OF
    CONFLICTS OF LAWS § 139 cmts. c & d. As BCE has not
    informed us of a conflict, cites Delaware law extensively (with
    comparatively few Canadian decisions noted), and concedes that
    the law in Canada is not materially different than Delaware, we
    rely on Delaware authority in reaching our conclusions. See
    Huber, 
    469 F.3d at 74
    .
    We recognize that BCE has informed us of a true conflict
    on an issue the Debtors raise as an alternate sustaining
    ground—namely, whether the Debtors are entitled to the
    disputed documents under the fiduciary exception to the
    attorney-client privilege. Though that exception is well-
    entrenched in Delaware law, it does not exist in Canada. We
    deal with this issue more fully in Part VI.A.
    11
    In oral argument before our Court, BCE’s counsel stated
    that BCE and he “don’t think there’s a difference” between
    Delaware and Canadian law on the issues presented by this
    appeal.
    23
    IV.     Summary of the Law
    This appeal raises core questions about the proper
    operation of a corporate family’s centralized in-house legal
    department. Because answering those questions requires
    delving into a variety of concepts related to the co-client (or
    joint-client) privilege, its exceptions, its scope, and a lawyer’s
    ethical obligations, a summary of relevant law sets the backdrop.
    We begin with a basic review of the attorney-client
    privilege—and how it has been adapted to accommodate the
    corporate client. We continue with a discussion of how
    disclosing otherwise privileged communications to third parties
    waives the privilege. Next, we explore two oft-confused
    privileges: (1) the co-client (or joint-client) privilege, which
    applies when multiple clients hire the same counsel to represent
    them on a matter of common interest,12 and (2) the community-
    of-interest (or common-interest) privilege, which comes into
    play when clients with separate attorneys share otherwise
    privileged information in order to coordinate their legal
    activities. Neither the co-client nor community-of-interest
    privilege is effective in adverse litigation between the former
    clients, so we next discuss the contours of the adverse-litigation
    12
    Though the term “common interest” is used in describing
    both the co-client and community-of-interest privileges, these
    privileges are distinct. See Part IV.C.2, infra.
    24
    exception. Then, we explore how courts deal with joint
    representations that go wrong because of impermissible attorney
    conflicts of interest. Finally, we put all of these doctrines
    together to address how they interact in the modern corporate in-
    house counsel’s office.
    A.     The Attorney-Client Privilege
    The attorney-client privilege protects communications
    between attorneys and clients from compelled disclosure. It
    applies to any communication that satisfies the following
    elements: it must be “(1) a communication (2) made between
    privileged persons (3) in confidence (4) for the purpose of
    obtaining or providing legal assistance for the client.”
    RESTATEMENT (THIRD) OF THE LAW GOVERNING LAWYERS § 68
    (2000). “Privileged persons” include the client, the attorney(s),
    and any of their agents that help facilitate attorney-client
    communications or the legal representation. Id. § 70.
    The attorney-client privilege is the oldest of the common-
    law privileges. Klitzman, Klitzman & Gallagher v. Krut, 
    744 F.2d 955
    , 960 (3d Cir. 1984). Like all privileges, it is an
    exception to the common-law maxim that the public has a right
    to “‘every man’s evidence.’” United States v. Bryan, 
    339 U.S. 323
    , 331 (1950) (quoting 8 J. WIGMORE, EVIDENCE § 2192 (3d
    ed. 1940)). Though initially confined to communications made
    in anticipation of litigation, American courts rejected that
    limitation at the outset. PAUL R. RICE, ATTORNEY-CLIENT
    25
    PRIVILEGE IN THE UNITED STATES § 1:12 (2d ed. 1999)
    (hereinafter “RICE”) (citing, e.g., Parker v. Carter, 
    4 Munf. 273
    ,
    
    1814 WL 667
    , at *9 (Va. 1814) (“The court is also of [the]
    opinion[] that [the privilege] is not confined to facts disclosed,
    in relation to suits actually depending at the time, but extends to
    all cases in which a client applies . . . to his counsel or attorney
    . . . for his aid in the line of his profession.”)). This is because
    so confining the privilege would discourage clients from seeking
    the advice of counsel before problems arise. Parker, 1814 WL
    at *9.
    As the Supreme Court has noted more recently, the
    purpose of the attorney-client privilege
    is to encourage full and frank communication
    between attorneys and their clients and thereby
    promote broader public interests in the
    observance of law and administration of justice.
    The privilege recognizes that sound legal advice
    or advocacy serves public ends and that such
    advice or advocacy depends upon the lawyer’s
    being fully informed by the client.
    Upjohn Co. v. United States, 449 U.S.383, 389 (1981); accord
    The Queen v. McClure, [2001] 
    1 S.C.R. 445
    , at ¶¶ 32–33 (Can.
    2001); Deutsch v. Cogan, 
    580 A.2d at 104
    . Because the
    privilege carries through policy purposes—encouraging
    attorney-client communication to enhance compliance with the
    26
    law and facilitating the administration of justice, the Supreme
    Court has not applied it mechanically. Upjohn, 449 U.S. at 392.
    It is essential that parties be able to determine in advance with
    a high degree of certainty whether communications will be
    protected by the privilege. Id. at 393; see also Deutsch, 
    580 A.2d at 106
    .
    As common-law courts developed the privilege in an age
    in which clients were almost exclusively natural persons, more
    modern courts sought to adapt it to the now ubiquitous corporate
    client. For more than a century, common-law courts have
    recognized that communications between corporate clients and
    their attorneys are indeed privileged. See Radiant Burners, Inc.
    v. Am. Gas Ass’n, 
    320 F.2d 314
    , 319 & n.7 (7th Cir. 1963)
    (citing English cases dated as early as 1833, and American cases
    as early as 1885, for the proposition that corporations can assert
    the attorney-client privilege).
    Because corporations act through human agents, the
    question of whose communications with the corporation’s
    attorneys are entitled to protection comes up often. RICE § 4:11.
    In Upjohn the Supreme Court rejected the so-called “control
    group theory”—that only communications between high-level
    managers and corporate attorneys merit protection. 449 U.S. at
    392. Instead, it held that when a corporation’s managers require
    its employees to give information to its attorneys in the course
    of providing legal advice, those communications also are
    protected. Id. at 396. This serves the policy goals of the
    27
    privilege—to enhance compliance with the law and facilitate the
    administration of justice—by encouraging open communication
    between attorneys and clients. Id. at 389, 394.
    The lesson for us is that it is important not to confuse
    these overarching policy goals with the means of achieving
    them. Communication between counsel and client is not, in and
    of itself, the purpose of the privilege; rather, it only protects the
    free flow of information because it promotes compliance with
    law and aids administration of the judicial system. Cf. United
    States v. Zolin, 
    491 U.S. 554
    , 563 (1989) (explaining that
    attorney-client communication facilitating fraud is not
    privileged because that sort of communication impedes the
    administration of justice). Thus, following Upjohn’s lead in not
    applying the privilege mechanically does not counsel in favor of
    applying the privilege anytime it might increase the flow of
    information; rather, Upjohn counsels a more nuanced inquiry
    into whether according a type of communication protection is
    likely to encourage compliance-enhancing communication that
    makes our system for resolving disputes more operable.
    B.      The Disclosure Rule
    A communication is only privileged if it is made “in
    confidence.” RESTATEMENT (THIRD) OF THE LAW GOVERNING
    LAWYERS § 68. In other words, if persons other than the client,
    its attorney, or their agents are present, the communication is not
    made in confidence, and the privilege does not attach. The
    28
    disclosure rule operates as a corollary to this principle: if a client
    subsequently shares a privileged communication with a third
    party, then it is no longer confidential, and the privilege ceases
    to protect it. See DEL. R. EVID. 510. This is because the act of
    disclosing signals that the client does not intend to keep the
    communication secret. RICE § 9:28. In addition, it prevents
    clients from engaging in strategic selective disclosure. United
    States v. Bernard, 
    877 F.2d 1463
    , 1465 (10th Cir. 1989). The
    privilege does, after all, hinder the truth-seeking process, and so
    we carefully police its use. United States v. Doe, 
    429 F.3d 450
    ,
    453 (3d Cir. 2005).13
    Disclosing a communication to a third party
    unquestionably waives the privilege. A harder question is
    whether the waiver also ends the privilege as to any related but
    not disclosed communications. In answering this question, our
    touchstone is fairness. See Tackett v. State Farm Fire & Cas.
    Ins. Co., 
    653 A.2d 254
    , 259 (Del. 1995); see also Westinghouse
    Elec. Corp. v. Republic of the Philippines, 
    951 F.2d 1414
    , 1426
    n.12 (3d Cir. 1991). When one party takes advantage of another
    by selectively disclosing otherwise privileged communications,
    courts broaden the waiver as necessary to eliminate the
    13
    In stating that we construe the privilege strictly, we do not
    mean that it is disfavored. As Upjohn, McClure, and Deutsch
    indicate, the attorney-client privilege is integral to the
    functioning of our legal system. Recognizing, however, that it
    limits the truth-seeking process, we carefully monitor it to
    prevent its abuse.
    29
    advantage. Zirn v. VLI Corp., 
    621 A.2d 773
    , 781–82 (Del.
    1993) (“The purpose underlying the rule of partial disclosure is
    one of fairness to discourage the use of the privilege as a
    litigation weapon.”); see also RICE § 9:31. Extending the
    waiver, however, is not a punitive measure, so courts do not
    imply a broader waiver than necessary to ensure that all parties
    are treated fairly.14 See RICE 9:31. Moreover, when the
    disclosure does not create an unfair advantage, courts typically
    limit the waiver to the communications actually disclosed. See
    In re Keeper of Records (Grand Jury Subpoena Addressed to
    XYZ Corp.), 
    348 F.3d 16
    , 24–25 (1st Cir. 2003); cf.
    Westinghouse, 
    951 F.2d at
    1427 n.14.
    C.    Privileged Information Sharing
    1.     The Co-Client          (or    Joint-Client)
    Privilege
    It is often expedient for two or more people to consult a
    single attorney. The rules of professional conduct allow a
    lawyer to serve multiple clients on the same matter so long as all
    clients consent, and there is no substantial risk of the lawyer
    being unable to fulfill her duties to them all. RESTATEMENT
    (THIRD) OF THE LAW GOVERNING LAWYERS §§ 128–31. Just as
    14
    This is not to say that district courts may not separately
    impose disclosure as an sanction for improper behavior; it
    merely means that the scope of the waiver is only as broad as
    necessary to remedy any unfair advantage.
    30
    in single-client representation, the lawyer and co-clients15 begin
    their relationship when the co-clients convey their desire for
    representation, and the lawyer consents. Id. § 14. Like single-
    client representation, nothing prevents joint representation from
    arising by implication, but, as a District Court in Maryland
    recently noted, courts must be careful not to imply joint
    representations too readily:
    What the Court takes exception to is [the
    plaintiff’s] effort to . . . argue, in effect, that a
    joint representation of Party A and Party B may
    somehow arise through the expectations of Party
    B alone, despite Party A’s views to the contrary.
    This position is untenable, because it would . . .
    allow the mistaken (albeit reasonable) belief by
    one party that it was represented by an attorney
    . . . to serve to infiltrate the protections and
    privileges afforded to another client.
    Neighborhood Dev. Collaborative v. Murphy, 
    233 F.R.D. 436
    ,
    441–42 (D. Md. 2005) (internal citations and quotation marks
    deleted). Moreover, as the Restatement details, it is important
    to remember that
    15
    We use the terms “co-clients” and “joint clients”
    interchangeably. Both refer to multiple clients engaging one or
    more common attorneys to represent them on a matter of interest
    to all.
    31
    clients of the same lawyer who share a common
    interest are not necessarily co-clients. Whether
    individuals have jointly consulted a lawyer or
    have merely entered concurrent but separate
    representations is determined by the
    understanding of the parties and the lawyer in
    light of the circumstances.
    Co-client representations must also be
    distinguished from situations in which a lawyer
    represents a single client, but another person with
    allied interests cooperates with the client and the
    client’s lawyer.
    RESTATEMENT (THIRD) OF THE LAW GOVERNING LAWYERS § 75
    cmt. c (internal cross-references omitted).
    Once begun, a co-client representation generally
    continues until a client discharges the lawyer or the lawyer
    withdraws. Id. § 31. In addition, numerous courts have
    recognized that the relationship may terminate by implication.
    Fed. Deposit Ins. Corp. v. Ogden Corp., 
    202 F.3d 454
    , 463 (1st
    Cir. 2000) (“A joint attorney-client relationship remains intact
    until it is expressly terminated or until circumstances arise that
    readily imply to all the joint clients that the relationship is
    over.”) (emphasis in original); see also Flynt v. Brownfield,
    Bowen, & Bally, 
    882 F.2d 1048
    , 1051 (6th Cir. 1989) (holding
    that terminating attorney-client relationship requires “conduct
    32
    dissolving the essential mutual confidence” between them); In
    re Dow, 
    132 B.R. 853
    , 858 (Bankr. S. D. Ohio 1991) (same). In
    particular, a joint representation terminates when it becomes
    clear to all parties that the clients’ legal interests have diverged
    too much to justify using common attorneys. RICE § 2:4 (citing
    Mass. Eye & Ear Infirmary v. QLT Phototherapeutics, Inc., 
    167 F. Supp. 2d 128
    , 129 (D. Mass. 2001)).
    While it is permissible for lawyers and clients to limit the
    scope of representation in a single-client representation, see
    RESTATEMENT (THIRD) OF THE LAW GOVERNING LAWYERS
    § 19, it is particularly common in co-client situations because of
    the limited congruence of the clients’ interests. As the
    Restatement notes, a co-client relationship is limited by “the
    extent of the legal matter of common interest.” Id. § 75 cmt. c.
    While written agreements limiting the scope of a joint
    representation might be preferable, nothing requires this so long
    as the parties understand the limitations.
    The District Court for the Northern District of California
    noted in Sky Valley Ltd. P’ship v. ATX Sky Valley Ltd., 
    150 F.R.D. 648
    , 652–53 (N.D. Cal. 1993), that a wide variety of
    circumstances are relevant to the determination of whether two
    or more parties intend to create a joint-client relationship,
    particularly how the parties interact with the joint attorneys and
    with each other. These same circumstances are relevant to
    33
    determining the scope of any joint representation.16 The keys to
    deciding the scope of a joint representation are the parties’ intent
    and expectations, and so a district court should consider
    carefully (in addition to the content of the communications
    themselves) any testimony from the parties and their attorneys
    on those areas. As explained in section D of this Part, finding
    too broad the scope of a joint representation gives the parties
    more control over each other’s ability to waive the privilege
    than they intended, and it subjects them to losing it in litigation
    with one another.
    When co-clients and their common attorneys
    communicate with one another, those communications are “in
    confidence” for privilege purposes. Hence the privilege protects
    those communications from compelled disclosure to persons
    outside the joint representation. Moreover, waiving the joint-
    client privilege requires the consent of all joint clients.
    RESTATEMENT (THIRD) OF THE LAW GOVERNING LAWYERS
    § 75(2). A wrinkle here is that a client may unilaterally waive
    the privilege as to its own communications with a joint attorney,
    so long as those communications concern only the waiving
    client; it may not, however, unilaterally waive the privilege as

    Common-Interest) Privilege18
    17
    As the Reporter’s Note in the Restatement laments, the
    caselaw on this point is not as uniform as one would hope. Id.
    § 75 Reporter’s Note cmt. e. The divergence seems to rest on
    difficulties in understanding the following statement from
    Wigmore’s treatise: “Where the consultation was had by several
    clients jointly, the waiver should be joint for joint statements,
    and neither could waive for the disclosure of the other’s
    statements; yet neither should be able to obstruct the other in the
    disclosure of the latter’s own statements.” 8 J. WIGMORE,
    EVIDENCE § 2328 (J. McNaughton rev. 1961) (second emphasis
    added). Obtuse as this statement may seem, we believe that the
    Restatement’s interpretation of it is sensible and, in any event,
    correctly states the law in Delaware. Cf. Interfaith Hous. Del.,
    Inc. v. Town of Georgetown, 
    841 F. Supp. 1393
    , 1402 (D. Del.
    1994) (predicting that one common-interest client’s waiver of
    the privilege does not waive it on behalf of all common-interest
    clients).
    18
    Because the issues in our case involve clients of the same
    attorneys, not clients with separate counsel, which would call for
    a community-of-interest analysis, the rest of this section may
    seem surplusage. But because the District Court (erroneously)
    ruled that the Debtors and BCE were in a “community of
    interest,” we examine the contours of that privilege. Indeed,
    much of the caselaw confuses the community-of-interest
    privilege (which is the same as the “common-interest privilege,”
    35
    Recognizing that it is often preferable for co-defendants
    represented by different attorneys in criminal proceedings to
    coordinate their defense, courts developed the joint-defense
    privilege. In its original form, it allowed the attorneys of
    criminal co-defendants to share confidential information about
    defense strategies without waiving the privilege as against third
    parties. Moreover, one co-defendant could not waive the
    privilege that attached to the shared information without the
    consent of all others.19 Later, courts replaced the joint-defense
    privilege, which only applied to criminal co-defendants, with a
    broader one that protects all communications shared within a
    proper “community of interest.” whether the context be criminal
    or civil.20 RICE § 4:35; see also Andrew R. Taggart, Parent-
    Subsidiary Communications & the Attorney-Client Privilege, 65
    see RESTATEMENT (THIRD) OF THE LAW GOVERNING LAWYERS
    § 76 Reporter’s Note cmt.b.) with the co-client privilege. Thus
    it is important to detail the community-of-interest privilege for
    the purpose of explaining how it and the co-client privilege
    differ, and why only the latter applies in this case.
    19
    For a history of the joint-defense privilege, see generally
    Craig S. Lerner, Conspirators’ Privilege & Innocents’ Refuge:
    A New Approach to Joint Defense Agreements, 77 NOTRE DAME
    L. REV. 1449, 1480–90 (2002).
    20
    According to the Restatement, the community-of-interest
    privilege has completely replaced the old joint-defense privilege
    for information sharing among clients with different attorneys.
    Thus, courts should no longer purport to apply the joint-defense
    privilege. RESTATEMENT (THIRD) OF THE LAW GOVERNING
    LAWYERS § 76 Reporter’s Note cmt. b.
    36
    U. CHI. L. REV. 315 (1998). Thus, the community-of-interest
    privilege allows attorneys representing different clients with
    similar legal interests to share information without having to
    disclose it to others. It applies in civil and criminal litigation,
    and even in purely transactional contexts. RICE 4:35;
    RESTATEMENT (THIRD) OF THE LAW GOVERNING LAWYERS
    § 76.
    Two aspects of the modern community-of-interest
    privilege are noteworthy. First, to be eligible for continued
    protection, the communication must be shared with the attorney
    of the member of the community of interest. Cf. Ramada Inns,
    Inc. v. Dow Jones & Co., 
    523 A.2d 968
    , 972 (Del. Super. Ct.
    1986) (emphasizing that the relevant Delaware evidentiary rule
    protects communications disclosed to an attorney). Sharing the
    communication directly with a member of the community may
    destroy the privilege.21 Second, all members of the community
    must share a common legal interest in the shared
    communication. RICE § 4:35. Delaware Rule of Evidence
    502(b)(3), which sets out the State’s version of the community-
    of-interest privilege, incorporates both requirements (that the
    clients’ separate attorneys share information and that the clients
    have a common legal interest):
    21
    Neither the Restatement nor Professor Rice emphasize this
    requirement, though it appears in the plain text of the relevant
    Delaware evidentiary rule, and Professor Rice acknowledges it.
    See DEL R. EVID. 502(b)(3); RICE § 4:35 & n.44.1.
    37
    A client has a privilege to refuse to disclose and
    to prevent any other person from disclosing
    confidential communications[,] made for the
    purpose of facilitating the rendition of
    professional legal services to the client . . .[,] by
    the client or the client’s representative or the
    client’s lawyer or a representative of the lawyer to
    a lawyer or a representative of a lawyer
    representing another in a matter of common
    interest.
    DEL. R. EVID. 502(b)(3).
    The requirement that the clients’ separate attorneys share
    information (and not the clients themselves) derives from the
    community-of-interest privilege’s roots in the old joint-defense
    privilege, which (to repeat) was developed to allow attorneys to
    coordinate their clients’ criminal defense strategies. See
    Chahoon v. Commw., 
    21 Gratt. 822
    , 
    1871 WL 4931
    , at *11 (Va.
    1871). Because the common-interest privilege is an exception
    to the disclosure rule, which exists to prevent abuse, the
    privilege should not be used as a post hoc justification for a
    client’s impermissible disclosures. The attorney-sharing
    requirement helps prevent abuse by ensuring that the common-
    interest privilege only supplants the disclosure rule when
    attorneys, not clients, decide to share information in order to
    coordinate legal strategies.
    38
    Similarly, the congruence-of-legal-interests requirement
    ensures that the privilege is not misused to permit unnecessary
    information sharing. In a leading case, a District Court in South
    Carolina explained the contours of the requirement:
    A community of interest exists among different
    persons or separate corporations where they have
    an identical legal interest with respect to the
    subject matter of a communication between an
    attorney and a client concerning legal advice. The
    third parties receiving copies of the
    communication and claiming a community of
    interest may be distinct legal entities from the
    client receiving the legal advice and may be a
    non-party to any anticipated or pending litigation.
    The key consideration is that the nature of the
    interest be identical, not similar, and be legal, not
    solely commercial. The fact that there may be an
    overlap of a commercial and a legal interest for a
    third party does not negate the effect of the legal
    interest in establishing a community of interest.
    Duplan Corp. v. Deering Milliken, Inc., 
    397 F. Supp. 1146
    ,
    1172 (D.S.C. 1974).
    The Restatement takes a more flexible approach than
    Duplan toward the similarity and types of interests that qualify
    as “common”: “[T]he common interest . . . may be either legal,
    39
    factual, or strategic in character. The interests of the separately
    represented clients need not be entirely congruent.”
    RESTATEMENT (THIRD) OF THE LAW GOVERNING LAWYERS § 76
    cmt. e. Professor Rice criticizes Duplan’s strictness and cites a
    few cases announcing that the interest need not be identical
    (though maintaining, contrary to the Restatement, that the
    interest must be legal, rather than “factual or strategic”). RICE
    § 4:36 (citing, e.g., SCM Corp. v. Xerox Corp., 
    70 F.R.D. 508
    ,
    524–25 (D. Conn. 1976) (Newman, J.) (holding that legal
    interests must be “demonstrably common” or the clients must
    have a “substantial” risk of shared exposure to justify privileged
    information-sharing)). Rice, however, still recognizes Duplan
    as the leading approach. 
    Id.
     (“This . . . standard . . . coined in
    Duplan . . . has been widely followed.”). The Delaware courts
    seem not to have taken a position on whether the common legal
    interest must be identical, and we need not resolve the
    congruence-of-legal-interests question here. For our purposes,
    it is sufficient to recognize that members of the community of
    interest must share at least a substantially similar legal interest.
    We conclude with two points of caution. First, the
    privilege only applies when clients are represented by separate
    counsel. Thus, it is largely inapplicable to disputes like this one
    that revolve around corporate family members’ use of common
    attorneys (namely, centralized in-house counsel).22 Second,
    22
    This means that BCE’s invocation of the “common
    interest” privilege in the Bankruptcy Court was out of place, as
    BCE has never asserted that the parties were represented by
    40
    while the Restatement (confusingly) uses the term “common
    interest” to describe the congruence of the parties’ interests in
    both co-client and community-of-interest situations, the
    concepts are not the same. Compare RESTATEMENT (THIRD) OF
    THE LAW GOVERNING LAWYERS § 75(1) (“If two or more
    persons are jointly represented by the same lawyer in a matter,
    a communication of either co-client that . . . relates to matters of
    common interest is privileged as against third persons.”), with
    id. § 76(1) (“If two or more clients with a common interest in a
    litigated or nonlitigated matter are represented by separate
    lawyers and they agree to exchange information concerning the
    matter, a communication of any such client . . . is privileged as
    against third persons.”); cf. id. § 76 cmt. e & Reporter’s Note
    cmt. b (explaining that co-client and community-of-interest
    situations differ). In particular, because co-clients agree to share
    all information related to the matter of common interest with
    each other and to employ the same attorney, their legal interests
    must be identical (or nearly so) in order that an attorney can
    represent them all with the candor, vigor, and loyalty that our
    ethics require. See Ogden, 
    202 F.3d at 461
    . In the community-
    of-interest context, on the other hand, because the clients have
    separate attorneys, courts can afford to relax the degree to which
    clients’ interests must converge without worrying that their
    separate counsel who properly shared information. Confusing
    as this area of law is, parties asserting the privilege (who,
    incidentally, bear the burden of proving it applies) are expected
    to explain themselves with more precision than BCE has
    throughout this litigation.
    41
    attorneys’ ability to represent them zealously and single-
    mindedly will suffer.
    D.     The Exception for Adverse Litigation
    The great caveat of the joint-client privilege is that it only
    protects communications from compelled disclosure to parties
    outside the joint representation. When former co-clients sue one
    another, the default rule is that all communications made in the
    course of the joint representation are discoverable. DEL. R.
    EVID. § 502(d)(6); RESTATEMENT (THIRD) OF THE LAW
    GOVERNING LAWYERS § 75(2). This rule has two bases: (1) the
    presumed intent of the parties, and (2) the lawyer’s fiduciary
    obligation of candor to both parties. Id. § 75 cmt. d. According
    to the Restatement, it is permissible for co-clients to agree in
    advance to shield information from one another in subsequent
    adverse litigation, though the drafters concede finding no direct
    authority for that proposition.23 Id. Reporter’s Note cmt d.
    BCE argues that the default rule should be flipped when
    the joint clients are a parent company and its wholly owned
    subsidiary—i.e., courts should assume that communications
    23
    Indeed, the only case we have found dealing with such an
    agreement is In re Mirant Corp., 
    326 B.R. 646
    , 652 (Bankr.
    N.D. Tex. 2005) (applying Georgia law), in which the
    Bankruptcy Court refused to give it effect. We have no
    occasion here to predict whether Delaware courts would enforce
    such agreements.
    42
    generated in the course of the joint representation are not
    discoverable in adverse litigation. BCE’s rationale is that no
    parent would want its subsidiary to be able to invade the
    privilege in subsequent litigation, and so courts should not
    presume that intent. Moreover, because parents and wholly
    owned subsidiaries share the same interests, the parent’s intent
    (to shield information) effectively controls.
    Delaware courts have recognized that parents and their
    wholly owned subsidiaries have the same interests because all
    of the duties owed to the subsidiaries flow back up to the parent.
    Cf. Anadarko, 
    545 A.2d at 1174
     (“[I]n a parent and wholly-
    owned subsidiary context, the directors of the subsidiary are
    obligated only to manage the affairs of the subsidiary in the best
    interests of the parent and its shareholders.”). While we
    normally assume that a corporation’s primary interest is in
    maximizing its economic value, the only interest of a wholly
    owned subsidiary is in serving its parent. 
    Id. at 1174
    . That
    doing so may not always involve maximizing the subsidiary’s
    economic value is of little concern. Trenwick Am. Litig. Trust
    v. Ernst & Young LLP, 
    906 A.2d 168
    , 192 (Del. Ch. 2006).24 If
    24
    As Vice Chancellor Strine noted in that case, there is
    nothing wrong (or even unusual) about a parent causing its
    solvent wholly owned subsidiary to act in a way that benefits the
    corporate family but harms the individual subsidiary. He
    explained:
    Assume for a moment that Trenwick [parent]
    itself never went bankrupt. Imagine further that
    it had bought another insurer and pledged a key
    43
    the subsidiary is not wholly owned, however, in the interest of
    protecting minority shareholders we revert to requiring that
    whoever controls the subsidiary seek to maximize its economic
    value with requisite care and loyalty. See 
    id.
     at 192 n.66.
    Similarly, if the subsidiary is insolvent, we require the same in
    the interest of protecting the subsidiary’s creditors. 
    Id.

    n.96 (approving In re Scott Acquisition Corp., 
    244 B.R. 283
    ,
    286 (Bankr. D. Del. 2006) (holding that the fiduciary duties of
    directors of an insolvent wholly owned subsidiary inure to the
    benefit of the subsidiary’s creditors)); see also N. Am. Catholic
    asset of Trenwick America [subsidiary] as
    security for the purchase price. The purchase
    goes wrong and causes Trenwick to become less
    profitable, but not insolvent. To satisfy its
    creditors, Trenwick causes Trenwick America to
    sell the key pledged asset and uses the proceeds to
    pay off the acquisition debt. As a result,
    Trenwick America is less profitable and less
    valuable. In this scenario, even though the course
    of events posed no prospect of benefit for
    Trenwick America when it is conceived solely as
    an entity, there would be nothing troubling about
    it from a fiduciary perspective. Rather, the
    scenario would involve a garden-variety situation
    when a parent corporation used the asset value of
    one of its wholly-owned subsidiaries to help it
    finance and absorb the down-side of the parent’s
    larger business strategy.

    , at
    *7 (“[T]he creditors of an insolvent corporation have standing
    to maintain derivative claims against directors on behalf of the
    corporation for breaches of fiduciary duties. The corporation’s
    insolvency makes the creditors the principal constituency
    injured by any fiduciary breaches that diminish the firm’s value.
    Therefore, equitable considerations give creditors standing to
    pursue derivative claims against the directors of an insolvent
    corporation. Individual creditors of an insolvent corporation
    have the same incentive to pursue valid derivative claims on its
    behalf that shareholders have when the corporation is solvent.”)
    (emphasis in original) (internal citations and quotation marks
    omitted).
    In the context of a joint attorney representing a parent
    and its solvent wholly owned subsidiary, BCE’s argument that
    we should flip the normal default rule (that all information
    shared in the course of a joint representation is not privileged in
    subsequent adverse litigation between the former joint clients)
    has some appeal, as it probably is more in line with the typical
    parent company’s intent. But because parent-subsidiary
    relationships often change, having opposite default rules for
    wholly owned, solvent subsidiaries, and not-wholly owned or
    insolvent subsidiaries, seems unwieldy. In the course of a joint
    representation, a subsidiary could go from being wholly owned
    and solvent to majority-owned or insolvent (or both). Under
    those circumstances, it is not clear which default rule BCE
    would have us apply. Because of the need for clarity and
    45
    certainty in privilege law, see Upjohn, 449 U.S. at 393, creating
    multiple, ever-shifting default rules would be unwise. Simply
    following the default rule against information shielding creates
    simpler, and more predictable, ground rules.
    Moreover, BCE’s argument overlooks the joint attorney’s
    fiduciary obligations to both parties. In undertaking a joint
    representation, the prospective joint attorney must always
    consider whether she can fulfill her duties to each co-client. See
    RESTATEMENT (THIRD) OF THE LAW GOVERNING LAWYERS
    §§ 128–31. When the co-clients desire to shield information
    from one another, this inquiry becomes more difficult in light of
    the prospective joint attorney’s duty of candor to each. See id.
    § 60 cmt. l. In situations in which the subsidiary may become
    either partially owned or insolvent, a prospective joint attorney
    would have to consider her ability not only to counsel both
    clients, but to do so in the face of an information-shielding
    agreement that could harm one of them. Thus applying the
    default rule against information shielding, absent an affirmative
    agreement to shield, makes good sense. The rule is widely
    accepted and dovetails with the joint attorney’s duty of candor.
    We predict that Delaware courts would apply the adverse
    litigation exception in all situations, even those in which the
    joint clients are wholly owned by the same person or entity.
    E.     When Joint Representation Goes Awry: The
    Eureka Principle
    46
    The Restatement’s conflicts rules provide that when a
    joint attorney sees the co-clients’ interests diverging to an
    unacceptable degree, the proper course is to end the joint
    representation. RESTATEMENT (THIRD) OF THE LAW GOVERNING
    LAWYERS § 121 cmts. e(1)–(2). As the Court of Appeals for the
    D.C. Circuit noted in Eureka Inv. Corp. v. Chicago Title Ins.
    Co., 
    743 F.2d 932
     (D.C. Cir. 1984) (per curiam), courts are
    presented with a difficult problem when a joint attorney fails to
    do that and instead continues representing both clients when
    their interests become adverse. 
    Id.
     at 937–38. In this situation,
    the black-letter law is that when an attorney (improperly)
    represents two clients whose interests are adverse, the
    communications are privileged against each other
    notwithstanding the lawyer’s misconduct. Id.; see also 8 J.
    WIGMORE, EVIDENCE § 2312 (McNaughton rev. ed. 1961).
    The context of the Eureka case was the joint
    representation of an insured and insurer. Over the course of the
    litigation, the parties began to disagree. The insured, a
    developer trying to effect a condo conversion, wanted to settle
    in order to get its conversion plans back on track. The title
    insurer, on the other hand, wanted to continue opposing liability
    and would not agree to within-policy-limits settlement terms.
    Having decided that the insurer’s refusal to settle was tortious,
    the insured entered into a unilateral settlement with its
    adversaries and promptly sued the insurer for indemnification
    and consequential damages. The trouble was that the insured
    continued to use the joint attorneys throughout the process,
    47
    relying on their advice in deciding to enter into a unilateral
    settlement and to sue the insurer. Thus, upon filing its action,
    the insurer sought discovery of the insured’s communications
    with the joint attorneys in the hope that those communications
    would support the affirmative defense of non-cooperation. The
    insurer argued that because those communications were
    generated during the attorneys’ joint representation of the parties
    on the claim against the insured, they were discoverable in an
    action between the joint clients.
    The Court rejected the insurer’s argument, holding
    instead that “[t]he policy behind [the co-client privilege]—to
    encourage openness and cooperation between joint
    clients—does not apply to matters known at the time of
    communication not to be in the common interest of the
    attorney’s two clients.” Eureka, 
    743 F.2d at 937
    . It emphasized
    that both the insured and the joint attorneys thought that they
    had begun a separate, individual representation of the insured on
    the insurance bad-faith claim that was distinct from the
    underlying liability action, calling these understandings
    “crucial.” 
    Id.
     Noting the attorneys’ potential ethical violations,
    the Court concluded that they were of no moment: “[C]ounsel’s
    failure to avoid a conflict of interest should not deprive the
    client of the privilege. The privilege, being the client’s, should
    not be defeated solely because the attorney’s conduct was
    ethically questionable.” 
    Id. at 938
    . Though not yet explicitly
    adopted by the Delaware courts, the Eureka principle is widely
    accepted. See RESTATEMENT (THIRD) OF THE LAW GOVERNING
    48
    LAWYERS § 60 cmt. l.; RICE 4:33.
    F.     Putting It All Together: Parents, Subsidiaries,
    and the Modern Corporate Counsel’s Office
    “A striking development in the legal profession . . . has
    been the rapid growth in both importance and size of in-house,
    or corporate, counsel.” Abram Chayes & Antonia Chayes,
    Corporate Counsel and the Elite Law Firm, 37 STAN. L. REV.
    277, 277 (1985). The roles of in-house counsel are many, e.g.,
    overseeing the corporation’s compliance with myriad regulatory
    regimes. The primary advantages of in-house (rather than
    outside) counsel are the breadth of their knowledge of the
    corporation and their ability to begin advising senior
    management on important transactions at the earliest possible
    stage, often well before anyone would think to hire a law firm.
    See id. at 280–81; Carl D. Liggio, The Changing Role of
    Corporate Counsel, 46 EMORY L.J. 1201, 1208 (1997). While
    there is much debate over how corporate counsel should go
    about promoting compliance with law (e.g., the usefulness of
    “noisy withdrawal” requirements versus going up the corporate
    chain with concerns), both sides of the debate seem to see in-
    house counsel as the “front lines” of the battle to ensure that
    compliance while preserving confidential communications.
    Compare William W. Horton, A Transactional Lawyer’s
    Perspective on the Attorney-Client Privilege: A Jeremiad for
    Upjohn, 61 BUS. LAW. 95 (2005), with Letter from Susan P.
    Koniak, Roger C. Cramton & George M. Cohen (endorsed by
    49
    named academics) to Securities Exchange Commission (Dec.

    Because in-house counsel are crucial and clear rules are needed
    to sort out attorney-client privilege problems (particularly for
    corporate groups), this section sets out how the various
    principles we have discussed apply to a parent company’s in-
    house counsel.
    1.     Intra-group Information Sharing:
    Parents and Subsidiaries as Joint
    Clients
    Because parent companies often centralize the provision
    of legal services to the entire corporate group in one in-house
    legal department, it is important to consider how the disclosure
    rule affects the sharing of information among corporate
    affiliates. Recognizing that any other result would wreak havoc
    on corporate counsel offices, courts almost universally hold that
    intra-group information sharing does not implicate the
    disclosure rule. This result is unquestionably correct. The
    cases, however, vary in how they reach the result. The Glidden
    case, which both parties cite, illustrates the conceptual muddle:
    The universal rule of law, expressed in a variety
    of contexts, is that the parent and subsidiary share
    a community of interest, such that the parent (as
    well as the subsidiary) is the “client” for purposes
    50
    of the attorney-client privilege. See Crabb v.
    KFC Nat'l Management Co., No. 91-5474, 
    1992 WL 1321
     (6th Cir. Jan.6, 1992) (“‘The cases
    clearly hold that a corporate ‘client’ includes not
    only the corporation by whom the attorney is
    employed or retained, but also parent, subsidiary
    and affiliate corporations.”’ (quoting United
    States v. AT & T, 
    86 F.R.D. 603
    , 616 (D.D.C.
    1979))). Consequently, disclosure of legal advice
    to a parent or affiliated corporation does not work
    a waiver of the confidentiality of the document,
    because of the complete community of interest
    between parent and subsidiary. 
    Id. at * 2
    .
    Numerous courts have recognized that, for
    purposes of the attorney client privilege, the
    subsidiary and the parent are joint clients, each of
    whom has an interest in the privileged
    communications. See, e.g., Polycast Tech. Corp.
    v. Uniroyal, Inc., 
    125 F.R.D. 47
    , 49 (S.D.N.Y.
    1989); Medcom Holding Co. v. Baxter Travenol
    Lab., 
    689 F. Supp. 841
    , 842 (N.D. Ill. 1988).
    Glidden Co. v. Jandernoa, 
    173 F.R.D. 459
    , 472–73 (W.D. Mich.
    1997) (applying Delaware law). In the above-quoted paragraph,
    the Court calls the members of the corporate family a single
    client and joint clients—all in the same breath. Moreover, it
    invokes the community-of-interest privilege, which we
    explained in section C of this Part, supra, applies only when the
    51
    parties have separate counsel. In quoting Glidden, we do not
    mean to single out that Court for criticism, for there are many
    cases that reach the result of non-waiver of privilege without
    persuasively explaining how.
    Courts typically offer versions of three arguments for not
    construing the sharing of communications within the corporate
    family as a waiver: (1) the members of the corporate family
    comprise one client, see, e.g., Glidden, 173 F.R.D. at 472;
    United States v. Am. Tel. & Tel. Co., 86, F.R.D. 603, 616
    (D.D.C. 1979); (2) the members of the corporate family are joint
    clients, see, e.g., Glidden, 173 F.R.D. at 473; Polycast Tech.
    Corp. v. Uniroyal, Inc., 
    125 F.R.D. 47
    , 49 (S.D.N.Y. 1989);
    Medcom, 
    689 F. Supp. at 842
    ; and (3) the members of the
    corporate family are in a community of interest with one
    another. See, e.g., Glidden, 173 F.R.D. at 472; see generally
    JOHN K. VILLA, CORPORATE COUNSEL GUIDELINES § 1:22(C)
    (2006) (discussing community-of-interest and joint-client
    rationales); RICE § 4:24 & n.54 (discussing various rationales for
    not applying the disclosure rule). Of these three rationales, we
    believe only the second withstands scrutiny.
    Within the wholly owned corporate family, it
    superficially makes sense to hold, as BCE urges, that the family
    is really one client for purposes of the privilege and that the
    privilege is held exclusively by the parent because all fiduciary
    duties flow to the parent. Indeed, in other contexts courts have
    treated parents and their wholly owned subsidiaries as one
    52
    entity. For example, parents and their wholly owned
    subsidiaries cannot constitute a “combination” or “conspiracy”
    of two or more persons under the Sherman Act. Copperweld
    Corp. v. Independence Tube Corp., 
    467 U.S. 752
    , 772 (1984).
    The Supreme Court reasoned that parents and subsidiaries could
    not effectively “agree” for Sherman Act purposes because
    [a] parent and its wholly owned subsidiary have a
    complete unity of interest. Their objectives are
    common, not disparate; their general corporate
    actions are guided or determined not by two
    separate corporate consciousnesses, but one.
    They are not unlike a multiple team of horses
    drawing a vehicle under the control of a single
    driver. With or without a formal “agreement,” the
    subsidiary acts for the benefit of the parent, its
    sole shareholder. . . . [I]n reality a parent and a
    wholly owned subsidiary always have a unity of
    purpose or a common design. They share a
    common purpose whether or not the parent keeps
    a tight rein over the subsidiary; the parent may
    assert full control at any moment if the subsidiary
    fails to act in the parent’s best interests.
    
    Id.
     at 771–72 (internal citations and quotation marks omitted).
    Applying similar logic, courts have held that a parent cannot
    tortiously interfere with its subsidiary’s contracts merely by
    directing the subsidiary to breach the agreements. Boulevard
    53
    Assocs. v. Sovereign Hotels, Inc., 
    72 F.3d 1029
    , 1036 (2d Cir.
    1995) (applying Connecticut law).
    BCE also points out that Congress has recently pushed
    members of corporate families to act more in concert with one
    another by requiring the officers of public companies to certify
    each quarter that they “have designed such internal controls to
    ensure that material information relating to the issuer and its
    consolidated subsidiaries is made known to such officers by
    others within those entities.” 
    15 U.S.C. § 7241
    (a)(4)(B).
    According to SEC regulations, the general rule is that majority-
    owned subsidiaries must be consolidated for purposes of
    financial reporting. 
    17 C.F.R. § 210
    .3A–02(a). Thus our
    regulatory structure also treats the corporate family as a unified
    enterprise for at least some purposes.
    On the other hand, treating members of a corporate
    family as one client fails to respect the corporate form. It is a
    bedrock principle of corporate law in Delaware and elsewhere
    that courts must respect entity separateness unless doing so
    would work inordinate inequity. Pauley Petroleum, Inc. v.
    Cont’l Oil Co., 
    239 A.2d 629
    , 633 (Del. 1968); see also In re
    Owens Corning, 
    419 F.3d 195
    , 211 (3d Cir. 2005) (concluding
    that courts must “respect entity separateness absent compelling
    circumstances calling equity . . . into play”). By structuring its
    various activities by forming separate corporations, a parent
    company realizes numerous benefits, not the least of which are
    the liability shields. With that structure comes the responsibility
    54
    to treat the various corporations as separate entities. In a tort
    suit, for example, it is doubtful that we would treat the Debtors,
    Teleglobe, and BCE as one entity.
    We acknowledge that a core concept of Copperweld and
    Boulevard Associates is that when a legislature seeks to attach
    conspiracy-like liability,25 it rarely means to include the garden-
    variety situation in which one who controls a corporation directs
    that corporation to do something. After all, a corporation can
    only act at the direction of whoever controls it, and we do not
    think of every corporate action as a “conspiracy.” These
    decisions, though, are tethered to the statutes (or common-law
    causes of action) they interpret,26 and do not give us license to
    disregard entity separateness in other contexts. Thus they are
    inapplicable here.
    Put simply, BCE wants to have it both ways: it wants us
    to view the corporate group as a single client, and it wants the
    controlling entity to own the privilege in perpetuity. But the
    Supreme Court held in Commodity Futures Trading Comm’n v.
    Weintraub, 
    471 U.S. 343
    , 350 (1985), that control of the
    25
    By this we mean statutes or common-law causes of action
    that impose additional liability on bad behavior when two or
    more entities act in concert, usually to account for the additional
    danger that acting in concert engenders.
    26
    Indeed, there are conspiracy-type statutes that do attach
    liability to parent-subsidiary actions. See, e.g., Ashland Oil, Inc.
    v. Arnett, 
    875 F.2d 1271
    , 1281 (7th Cir. 1989) (holding that
    RICO liability attaches to intracorporate conspiracies).
    55
    privilege passes with control of the corporation, so it is unclear
    (even accepting BCE’s theory) that it is the initial corporate
    parent who should control the privilege unilaterally once the
    group breaks up. In any event, absent some compelling reason
    to disregard entity separateness, in the typical case courts should
    treat the various members of the corporate group as the separate
    corporations they are and not as one client.
    The community-of-interest rationale does not fit as a
    matter of black-letter law because the community-of-interest
    privilege only comes into play when parties are represented by
    separate counsel, which often is not the case for parents and
    subsidiaries.    See Part IV.C.2, supra.         Moreover, the
    community-of-interest privilege only applies when those
    separate attorneys disclose information to one another, not when
    parties communicate directly. Id. Finally, it assumes too much
    to think that members of a corporate family necessarily have a
    substantially similar legal interest (as they must for the
    community-of-interest privilege to apply, see id.) in all of each
    other’s communications. Thus, holding that parents and
    subsidiaries may freely share documents without implicating the
    disclosure rule because of a deemed community of interest
    stretches, we believe, the community-of-interest privilege too
    far.
    It makes the most sense, then, to rest not applying the
    disclosure rule to many intra-group disclosures on the ground
    that the members of the corporate family are joint clients. This
    56
    reflects both the separateness of each entity and the reality that
    they are all represented by the same in-house counsel (whether
    that counsel typically takes up office with the parent or with a
    subsidiary).
    2.     Keeping Control of the Privilege
    In its amicus brief, the Association of Corporate Counsel
    (“ACC”) has as a theme a parent company’s desire to keep
    control of the attorney-client privilege. One particular ACC
    (and BCE) concern is that disclosures to parent/subsidiary cross-
    directors risk creating broad joint representations that
    subsidiaries can use to invade the parent’s privilege in
    subsequent adverse litigation. Not so. In thinking about these
    situations, courts should keep in mind the definition of
    disclosure. For purposes of the disclosure rule, a disclosure
    occurs when the parent shares an otherwise confidential
    attorney-parent communication with an officer, director, or
    agent of a subsidiary in that capacity. See DEL. R. EVID. 510.
    Courts recognize corporate officers’ and directors’ ability to sit
    on multiple boards by “‘chang[ing] hats.’” United States v.
    Bestfoods, 
    524 U.S. 51
    , 69 (1998) (quoting Lusk v. Foxmeyer
    Health Corp., 
    129 F.3d 773
    , 779 (5th Cir. 1997)). Thus it does
    not break confidence to share an attorney-parent communication
    with an officer of the parent in her capacity as officer of the
    parent, even though she is also a director or officer of a
    subsidiary. Because this sort of information sharing is not a
    disclosure for purposes of the disclosure rule, courts need not
    57
    bother trying to apply a joint representation analysis to save the
    privilege in these situations, nor should they use such
    “disclosures” to find a joint representation with the relevant
    subsidiary.
    A similar concern is that courts may find too broad of a
    joint representation, which in a spin-off situation ends up
    allowing the subsidiary to invade the parent’s privilege. When,
    for example, in-house counsel of the parent seek information
    from various subsidiaries in order to complete the necessary
    public filings, the scope of the joint representation is typically
    limited to making those filings correctly. It does not usually
    involve jointly representing the various corporations on the
    substance of everything that underlies those filings.27 Contrary
    to the Debtors’ argument, it is permissible (subject, of course, to
    conflict rules) for attorneys and clients to limit the scope of a
    joint representation in a sophisticated manner; nothing requires
    construing the scope of a joint representation more broadly than
    the parties to it intend.
    27
    Indeed, in some of these circumstances in-house counsel
    may not need to represent the subsidiaries at all. When a parent
    company directs its subsidiaries’ employees to provide
    information to its in-house counsel that is critical to their
    representation of the parent, the communication may be
    privileged under Upjohn because of in-house counsel’s
    representation of the parent alone, thus obviating any need for
    these attorneys to represent the subsidiary as well. See Admiral
    Ins. Co. v. U.S. Dist. Ct. for the Dist. of Ariz., 
    881 F.2d 1486
    ,
    1493 n.6 (9th Cir. 1989); see also Upjohn, 
    449 U.S. 394
    .
    58
    3.     When Conflicts Arise
    It is inevitable that on occasion parents and subsidiaries
    will see their interests diverge, particularly in spin-off, sale, and
    insolvency situations. When this happens, it is wise for the
    parent to secure for the subsidiary outside representation.
    Maintaining a joint representation for the spin-off transaction
    too long risks the outcome of Polycast,28 125 F.R.D. at 49, and
    Medcom,29 
    689 F. Supp. at
    844—both cases in which parent
    companies were forced to turn over documents to their former
    28
    The privilege dispute in Polycast followed the sale of a
    wholly owned subsidiary. Before the sale, Uniroyal (the seller)
    and its subsidiary were jointly represented by in-house counsel.
    After the sale, Polycast (the buyer) sued Uniroyal for allegedly
    misrepresenting the subsidiary’s financial condition. It sought
    the production of notes taken by the subsidiary’s officer during
    a phone conversation with in-house counsel. The District Court
    ordered production because the subsidiary, now in Polycast’s
    control, waived the joint privilege in its favor. 125 F.R.D. at 51.
    As we explain in Part V.A.3, infra, we do not agree with much
    of the Polycast Court’s reasoning.
    29
    The facts and result of Medcom are substantially similar to
    those of Polycast. Essentially, the acquirer of a subsidiary sued
    the seller/parent for misrepresentation related to the sale, and
    sought production of documents produced while the subsidiary
    and seller/parent were jointly represented by in-house counsel.
    
    689 F. Supp. at 842
    . As with Polycast, we disagree with much
    of the Medcom Court’s reasoning, which we explain in Part
    V.A.3, infra.
    59
    subsidiaries in adverse litigation—not to mention the attorneys’
    potential for running afoul of conflict rules. That the companies
    should have separate counsel on the matter of the spin-off
    transaction, however, does not mean that the parent’s in-house
    counsel must cease representing the subsidiary on all other
    matters. After all, spin-off transactions can be in the works for
    months (or even years), and during that time it is proper (and
    obviously efficient) for in-house counsel to continue to represent
    the subsidiary (jointly or alone) on other matters.
    Once conflicts begin coming to the surface, the question
    of when to acquire separate counsel is often difficult. As
    Medcom and Polycast demonstrate, from the perspective of
    protecting the privilege the best answer is that once the parties’
    interests become sufficiently adverse that the parent does not
    want future controllers of the subsidiary to be able to invade the
    parent’s privilege, it should end any joint representation on the
    matter of the relevant transaction. Polycast, 125 F.R.D. at 49;
    Medcom, 
    689 F. Supp. at 844
    . This standard is, of course, only
    relevant if the parties have already begun a joint representation
    on that transaction; if they have not, then the parent has nothing
    to fear as far as the privilege goes (though other concerns, such
    as their fiduciary duties to their subsidiaries, may argue in favor
    of separating counsel).
    In sum, in-house counsel have available numerous means
    to protect a parent company’s privilege. By taking care not to
    begin joint representations except when necessary, to limit the
    60
    scope of joint representations, and seasonably to separate
    counsel on matters in which subsidiaries are adverse to the
    parent, in-house counsel can maintain sufficient control over the
    parent’s privileged communications.
    V.        Issues on Appeal
    A.    Whether the Debtors Are Entitled to
    Documents Generated in the Course of a
    BCE/Teleglobe Joint Representation
    The District Court ruled that any documents generated
    out of a BCE/Teleglobe joint representation are subject to
    discovery by the Debtors. BCE argues that the Court erred
    because the Debtors were not a party to any such joint
    representation. (BCE admits that its attorneys jointly represented
    it and Teleglobe on some matters; it denies that they jointly
    represented it and the Debtors.) Indeed, the Court did not enter
    a factual finding that any attorney jointly represented both BCE
    and any of the Debtors.30 Rather, the Court ruled that the
    30
    We understand that the Debtors argue otherwise. We note,
    however, that the Special Master wrote that “there was a joint
    representation by BCE’s attorneys of BCE and Teleglobe
    relating to a matter of common interest.” App. at A0047
    (emphasis added). Similarly, in affirming the Special Master,
    the District Court described his finding as a “joint representation
    of BCE and Teleglobe by in-house counsel for BCE . . . .” App.
    at A0013 (emphasis added). Because Teleglobe and the Debtors
    are separate entities, we cannot read these statements as finding
    61
    Debtors were entitled to the product of any BCE/Teleglobe joint
    representation because BCE had conceded this point.
    Alternatively, it noted the Debtors, as Teleglobe’s wholly owned
    subsidiaries, were entitled to the disputed documents as a matter
    of law, and in any event Teleglobe waived the privilege for the
    Debtors’ benefit in the Canadian insolvency proceedings. We
    address all three grounds.
    1.     Whether BCE’s Concession in the
    Bankruptcy Court Prevents it from
    Arguing that the Debtors are not
    Entitled to the Disputed Documents
    a.      Background
    The District Court determined that BCE made a binding
    concession that it would produce all documents arising out of
    any BCE/Teleglobe joint representation and waived any
    argument that the Debtors are not entitled to those documents.
    Given the convoluted nature of the record, it is important to
    understand what BCE argued at each stage of the litigation.
    The first reference to joint representation came from BCE
    itself; in a related proceeding before the Bankruptcy Court, BCE
    opposed a motion to compel production of various documents to
    the Creditors’ Committee in the course of a Rule 2004
    investigation. In its opposition brief, BCE stated that “BCE
    that the Debtors were also jointly represented.
    62
    attorneys consulted with attorneys, officers, or employees of
    Teleglobe, Inc. or its subsidiaries to discuss or provide legal
    advice in matters where BCE and Teleglobe Inc. (or its
    subsidiaries) shared a common legal interest.” App. at A01110.
    Furthermore, BCE declared that “such common interest
    privilege31 will continue to exist until the Debtors file a litigation
    against BCE.” App. at A01110. At the hearing, BCE stipulated
    that its in-house counsel, Michel Lalande, held documents
    relating to “two types of matters.” App. at A0172. The first
    category of documents “was where the common interest was
    involved.” App at A0172. The second category comprised
    documents in which “Mr. Lalande was counseling . . . BCE
    alone.” App. at A0172. The Bankruptcy Court ordered BCE to
    produce to the Debtors and Creditors’ Committee “the common
    interest documents.” App. at A0172. Indeed, BCE agreed to do
    so. In the course of the hearing, however, the parties never
    honed in on what the “common interest” was.
    The issue came up again when the Debtors filed suit. In
    front of the District Court (before it referred discovery matters
    to the Special Master), BCE stated in its initial brief in
    opposition to the motion to compel production that “documents
    were produced pursuant to the Bankruptcy Court’s Order
    because they were subject to the common interest privilege.
    31
    We reiterate that the term “common-interest privilege” is
    inapt here, as that term typically refers to the community-of-
    interest privilege. What BCE appears to have been asserting is
    a co-client privilege. See supra Part IV.C.
    63
    Those documents were shared with [various attorneys and
    accountants representing the Debtors].” App. at A0218. At the
    first hearing before the District Court, BCE described the
    situation thus: “[T]here were some places where BCE attorneys
    clearly worked with what they conceived of as the common
    interest of Teleglobe and BCE. And there were areas of
    common interest. Judge Walrath said . . . produce them . . . .
    We did.” App. at A00264. Again, none of these statements sets
    out a definition or clarified the perceived scope of the “common
    interest.”
    Another round of briefing followed the District Court’s
    reference to the Special Master. At a hearing before the Special
    Master, the Debtors’ attorney went through BCE’s Rule 2004
    privilege log and summarized that BCE claimed a “common-
    interest privilege” on documents covering the following
    subjects: “Teleglobe financing, financial transaction between
    Teleglobe and BCE, issuance and redemption of preferred
    shares . . .[,] [r]efinancing of bank facilities . . ., developing
    Teleglobe financial statements, . . . public disclosures, . . . .
    [and] Teleglobe restructuring.” App. at A00496–97. He further
    stated that “[BCE] claims a common interest on Project X, and
    so on. . . . [H]aving claimed common interests and having
    assigned lawyers to effectively represent both sides of the
    common interest, it would seem to us to be inconsistent now to
    say that we can’t have all documents relating to the common
    interests[,] particularly when we’re talking about documents that
    were reviewed and considered by our fiduciaries.” App. at
    64
    A00497.
    BCE responded that its in-house counsel provided limited
    legal services to Teleglobe on an ad hoc basis and that BCE’s
    in-house counsel did not serve the Debtors at all because they
    had their own counsel in Reston, Virginia. App. at A00497. As
    to Project X, BCE responded that in-house counsel Michel
    Lalande and Martine Turcotte provided very limited advice to
    Teleglobe on its public filings, its management representation
    letters, its board resolutions, and its engagement letter with an
    investment bank. App. at A00498. Moreover, BCE argued that
    this advice was limited in scope and all other Project X advice
    was provided solely to and for the benefit of BCE. In sum, BCE
    argued that “what [is reflected on the privilege log] is BCE-
    privileged advice, not advice . . . where BCE has a common
    interest with [Teleglobe], not advice given to [Teleglobe] or [the
    Debtors,] if there is any.” App. at A00503.
    Recognizing that there was a dispute whether the
    documents on the privilege log reflected advice provided solely
    to BCE (and thus outside of the scope of any joint
    representation), the Special Master ordered an audit of 50
    documents to “see if I can satisfy myself that they are what you
    [BCE] term exclusively related to advice provided to BCE.”
    App. at A00504. To clarify the issue, the Special Master asked:
    “[Y]ou’ve [BCE] given them [the Debtors] the documents that
    deal with advice provided [to Teleglobe], by lawyers who might
    have been representing both BCE and [Teleglobe] at the same
    65
    time, but have not given them documents that may have
    addressed [Teleglobe], but were only involved with advice given
    to BCE?” App. at A00505. BCE counsel responded, “That’s
    correct.” App. at A00505.
    After the Special Master ordered production of all of the
    documents, BCE clearly raised, in its brief in opposition to the
    Debtors’ motion in the District Court to affirm and adopt the
    Special Master’s decision, the issue of its obligation to turn over
    documents arising from its and Teleglobe’s joint representation
    by BCE in-house counsel. App. at A00826. This was probably
    a reaction to the Special Master’s finding that the joint
    representation was so broad in scope that it covered all advice
    rendered on Project X. In other words, BCE had not objected to
    producing the “common interest” documents so long as its
    understanding of the narrow scope of the common interest
    prevailed, but when the Special Master found a broad scope, it
    asserted that it need not produce the common-interest documents
    at all. The District Court rejected this argument out-of-hand,
    finding that BCE was bound by its concession in the Bankruptcy
    Court that it would produce to the Debtors and the Creditors’
    Committee all of the documents of common interest to BCE and
    Teleglobe.32
    32
    BCE also told the Bankruptcy Court that if its attorneys
    jointly represented BCE and the Debtors on a matter related to
    this case, it would produce any documents that arose out of that
    representation. But BCE claims that its attorneys did not in fact
    jointly represent those parties on any related matter, and the
    66
    b.     Merits
    BCE should not, the Debtors argue, be able to raise now
    the issue of whether they and BCE were part of a joint
    representation. They base this contention on issue waiver,
    judicial admission, and judicial estoppel grounds. We address
    each, as well as whether BCE’s waiver of the privilege in the
    Bankruptcy Court prospectively waived it as to any documents
    found to be within the scope of a BCE/Teleglobe joint
    representation.
    I.        Issue Waiver
    Our longstanding rule is that a party must raise an issue
    before the District Court in order to press it on appeal.33 To
    raise an issue, a party must present it with sufficient specificity
    District Court did not find otherwise. Thus the issue is whether
    the Court’s finding that BCE attorneys did jointly represent BCE
    and Teleglobe is sufficient to support its production order in
    favor of the Debtors.
    33
    As the Court of Appeals for the Fifth Circuit has noted,
    when a district court employs a special master, it may be that the
    parties must, to avoid waiver, raise all relevant issues before the
    master. See Harris Corp. v. Ericsson, Inc., 
    417 F.3d 1241
    , 1263
    (5th Cir. 2005). Because we conclude that BCE did properly
    raise before the Special Master whether its attorneys jointly
    represented the Debtors, we need not decide here whether a
    party must raise all issues before a special master to preserve
    them.
    67
    to allow the court to pass on it. See Keenan v. City of
    Philadelphia, 
    983 F.2d 459
    , 471 (3d Cir. 1992); accord Shell
    Petroleum, Inc. v. United States, 
    182 F.3d 212
    , 218 (3d Cir.
    1999) (“A party . . . must unequivocally put its position before
    the trial court at a point and in a manner that permits the court
    to consider its merits.”). At oral argument before the Special
    Master, BCE stated unequivocally that its in-house attorneys
    never represented the Debtors on anything related to Teleglobe’s
    restructuring. The Special Master was skeptical of this
    assertion, and asked the Debtors to respond to it. They stated
    that they were entitled to documents generated through a
    BCE/Teleglobe joint representation because they, as third-level
    wholly owned subsidiaries, were members of the same
    community of interest (once again, an instance where someone
    conflates the community-of-interest privilege with the co-client
    privilege). This exchange properly put before the Special
    Master the issue of whether the Debtors were (or needed to be)
    parties to the BCE/Teleglobe joint representation for production
    to be ordered. Moreover, BCE again raised the issue in its
    objections to the Special Master’s decision. App. at A00826.
    With this context, we cannot conclude BCE waived contending
    that it and the Debtors were not jointly represented on any
    matter relevant to this case.
    ii.        Judicial Admission
    The Debtors argue, however, that BCE’s statement to the
    Bankruptcy Court that it would turn over to the Debtors (and the
    68
    Creditors’ Committee) the “common interest” documents arising
    out of the BCE/Teleglobe joint representation was a binding
    judicial admission. To be binding, admissions must be
    unequivocal. Glick v. White Motor Co., 
    458 F.2d 1287
    , 1291
    (3d Cir. 1972). Similarly, they must be statements of fact that
    require evidentiary proof, not statements of legal theories. 
    Id.
    Applying those principles, BCE’s statements on any joint
    representation of BCE and the Debtors were never unequivocal.
    All references to a joint representation of BCE and the
    subsidiaries were couched in alternative language. See, e.g.,
    app. A01110 (“BCE attorneys consulted with attorneys, officers,
    or employees of Teleglobe, Inc. or its subsidiaries to discuss or
    provide legal advice in matters where BCE and Teleglobe, Inc.
    (or its subsidiaries) shared a common legal interest.”) (emphases
    added). To the extent that BCE admitted that it was obligated
    to turn over documents related to a joint representation on a
    matter of common interest, such an admission appears more like
    a statement of a legal theory or position than a statement about
    an issue of fact. Thus the judicial admission doctrine is not
    applicable.
    iii.    Judicial Estoppel
    Judicial estoppel prevents a party from “playing fast and
    loose with the courts” by adopting conflicting positions in
    different legal proceedings (or different stages of the same
    proceeding). Delgrosso v. Spang & Co., 
    903 F.2d 234
    , 241 (3d
    69
    Cir. 1990) (internal quotation marks and citations omitted).
    Here, the Debtors claim that BCE’s position that its attorneys
    never jointly represented it and the Debtors is impermissible
    because BCE relied on the joint representation in the
    Bankruptcy Court to assert a claim of privilege and because it
    induced the Bankruptcy Court and Special Master to rely on its
    concession that common-interest documents had been produced,
    only changing its position when the Special Master found its
    representations untrue. Judicial estoppel requires (1) a clear
    inconsistency and (2) that the party estopped obtain an unfair
    advantage from that inconsistency. In re Armstrong World
    Indus., Inc., 
    432 F.3d 507
    , 517–18 (3d Cir. 2005). This case
    looks more like a legitimate disagreement over the scope of any
    joint representation (mixed with a dose of sloppiness) than it
    does a bad faith attempt to mislead the courts. BCE’s position
    throughout has been that it has turned over the documents that
    arose out of a BCE/Teleglobe joint representation. It told the
    Bankruptcy Court—in equivocal terms—that there may have
    been a BCE/Debtors joint representation (and if so, it agreed to
    turn over any such documents). In front of the Special Master,
    BCE’s counsel specifically stated that its attorneys did not
    jointly represent the Debtors, and it has maintained that position
    since. In this limited context, that BCE was “playing fast and
    loose” with the courts appears too strong a statement. Perhaps
    it was being hyper-technical, and indeed up against the “too
    close for cricket” line, but that is as far as we can conclude on
    the record before us.
    70
    iv.     Implied Prospective
    Waiver of the Privilege
    To repeat, in the Bankruptcy Court BCE agreed to
    produce to the Debtors and the Creditors’ Committee what it
    termed the “common interest” documents to resolve a discovery
    dispute. It did not explain the scope of the common interest, but
    it did agree to produce the documents. BCE views the Debtors’
    contention that it may not now assert the privilege over other
    documents alleged to arise from the same joint representation as
    an implied prospective waiver argument. That analysis makes
    some sense.
    In discovery disputes, implied waivers are construed
    narrowly, In re Lott, 
    424 F.3d 446
    , 453 (6th Cir. 2005), and a
    party is only forced to produce documents under a prospective
    waiver theory if it agrees to disclose only favorable privileged
    documents while keeping for itself the unfavorable ones to gain
    an advantage in litigation. See Westinghouse, 
    951 F.2d at
    1426
    n.12 (“When a party discloses a portion of otherwise privileged
    materials while withholding the rest, the privilege is waived
    only as to those communications actually disclosed, unless a
    partial waiver would be unfair to the party’s adversary. If
    partial waiver does disadvantage the disclosing party’s
    adversary by, for example, allowing the disclosing party to
    present a one-sided story to the court, the privilege will be
    waived as to all communications on the same subject.”); accord
    Tackett, 
    653 A.2d at 260
     (holding that Delaware courts will only
    71
    find an prospective waiver when a party uses partial disclosure
    as a weapon).
    On the record here, it appears that BCE agreed to produce
    documents that fell within its understanding of the
    BCE/Teleglobe joint representation, not the masses of
    documents that the Special Master eventually found to fall
    within that category. Moreover, the Debtors have not argued
    that BCE is seeking an improper benefit by selectively
    disclosing documents. Thus we find no implied prospective
    waiver in favor of the Debtors as to whatever documents a court
    might conclude were part of a BCE/Teleglobe joint
    representation.
    2.     Whether the Community-of-Interest
    Privilege Entitles the Debtors to the
    Documents as a Matter of Law
    The District Court also ruled that the Debtors were
    entitled to the documents as a member of BCE’s community of
    interest. But as explained in Part IV.F.1, supra, it is not the case
    that parents and subsidiaries are in a community of interest as a
    matter of law. Moreover, the community-of-interest privilege
    only applies to parties represented by separate counsel, see Part
    IV.C.2, supra. Even some of the cases that the Debtors cite
    suggest more nuance than they admit. See, e.g., In re S. Air
    Transp., Inc., 
    255 B.R. 706
    , 711 (Bankr. S.D. Ohio 2000)
    (“Parent and subsidiary corporations generally share a common
    72
    interest, and may, in appropriate circumstances, be considered
    a single client for purposes of the attorney-client privilege.”
    (emphases added)). The majority—and more sensible—view is
    that even in the parent-subsidiary context a joint representation
    only arises when common attorneys are affirmatively doing
    legal work for both entities on a matter of common interest. See,
    e.g., Polycast, 125 F.R.D. at 49 (finding a joint representation
    when a parent’s officer and general counsel affirmatively
    advised subsidiary on how to comply with merger agreement to
    which parent and subsidiary were both parties). A broader rule
    would wreak havoc because it would essentially mean that in
    adverse litigation a former subsidiary could access all of its
    former parent’s privileged communications because the
    subsidiary was, as a matter of law, within the parent entity’s
    community of interest.
    3.     Whether Teleglobe’s Waiver of the
    Privilege for the Debtors’ Benefit in the
    Canadian Insolvency Proceedings
    Entitles them to the Documents
    The Debtors argue that they are entitled to any documents
    generated in the course of the BCE/Teleglobe joint
    representation because Teleglobe, through its Plan
    73
    Administrator in the Canadian insolvency proceedings, has
    waived the attorney-client privilege in their favor.34 The
    question before us is whether one party to a joint representation
    (Teleglobe) may unilaterally waive the privilege and thereby
    force the other (BCE) to turn over documents generated in the
    course of the joint representation to third parties (the Debtors).
    Put differently, the question is whether the co-client privilege is
    subject to a unilateral control rule (either co-client may waive
    the privilege unilaterally and thus force the other to turn over
    documents produced during the course of the joint
    representation to third parties) or a bilateral control rule (both
    clients must agree to waive the privilege in order for the waiver
    to take effect). The general answer is bilateral control. As
    explained in Part IV.D, supra, this rule is in the Restatement:
    [I]n the absence of an agreement with co-clients
    to the contrary, each co-client may waive the
    privilege with respect to that co-client’s own
    communications with the lawyer, so long as the
    communication relates only to the communicating
    and waiving client. One co-client does not have
    34
    That Teleglobe’s Plan Administrator purported to waive
    the privilege in the Debtors’ favor is not disputed. What is
    disputed is whether she had the authority under the Arrangement
    Act to do so. Because we hold that, under both Delaware and
    Canadian law, Teleglobe cannot waive the privilege without
    BCE’s consent in any event, we need not pass on the legal
    validity of Teleglobe’s purported waiver.
    74
    authority to waive the privilege with respect to
    another co-client’s communications to their
    common lawyer. If a document or other
    recording embodies communications from two or
    more co-clients, all those co-clients must join in
    a waiver, unless a nonwaiving co-client’s
    communication can be redacted from the
    document.”
    RESTATEMENT (THIRD) OF THE LAW GOVERNING LAWYERS § 75
    cmt. e. The Delaware District Court has predicted that
    Delaware law accords with this principle. Interfaith Hous. of
    Del., 
    841 F. Supp. at 1402
    , and the Delaware Court of Chancery
    (albeit in an unpublished decision) has agreed. Tenneco Auto.,
    Inc. v. El Paso Corp., 
    2001 WL 1456487
    , at *2 (Del. Ch. 2001).
    Canadian law on this point is the same. Ashburton Oil Ltd. v.
    Sharp, 67 B.C.L.R.2d 64, ¶ 24 (B.C. 1992).
    The cases the Debtors cite are not explicitly
    contradictory. In re Grand Jury Subpoenas, 
    902 F.2d 244
    , 248
    (4th Cir. 1990), for instance, deals with the transfer of the
    subsidiary’s own privilege from old to new management, not
    with joint representation.      Three other cases the Debtors
    cite—Bass Public Co. v Promus Cos., 
    868 F. Supp. 615
    (S.D.N.Y. 1994), Polycast, and Medcom—are muddier, as there
    are statements in all three that seem to disagree with the
    Restatement. See Bass, 
    868 F. Supp. at 621
     (stating that the
    bilateral control rule only applies if the two clients are actual or
    75
    potential co-defendants); Polycast, 125 F.R.D. at 50 (same);
    Medcom, 
    689 F. Supp. at
    844–45 (same).35 At the same time,
    none of the three decisions actually violated the Restatement.
    In Bass, one of the plaintiffs was the subsidiary (i.e., the joint
    client); it therefore was entitled to everything generated in the
    course of the joint representation as a matter of right. Bass, 
    868 F. Supp. at 617
    . In Polycast and Medcom, the disputed
    communications were between the subsidiary and the joint
    attorneys; thus the subsidiary could waive the privilege by itself.
    Medcom, 
    689 F. Supp. at 844
    ; Polycast, 125 F.R.D. at 48. Here,
    however, we have third parties seeking documents produced for
    35
    The problem is that Bass, Polycast, and Medcom all treat
    the old joint-defense privilege (which applied only to actual co-
    defendants in criminal litigation), see Part IV.C, supra, as a
    doctrine separate from the co-client and community-of-interest
    privileges. Those cases accord only joint-defense clients (again,
    actual co-defendants) the protection of the bilateral control rule
    (that neither co-client may unilaterally waive the privilege). See
    also Taggart, 65 U. CHI. L. REV. at 320 (arguing against the
    bilateral control rule). The Restatement has rejected this
    approach; it now treats the joint-defense privilege as obsolete
    and applies the bilateral control rule to the broader community-
    of-interest privilege. RESTATEMENT (THIRD) OF THE LAW
    GOVERNING LAWYERS § 76 cmts. b. & g. Moreover, the Bass,
    Polycast, and Medcom approach is inconsistent with even
    relatively old understandings of the co-client privilege. See,
    e.g., 8 J. WIGMORE, EVIDENCE § 2328 (J. McNaughton rev.
    1961) (explaining that co-clients are always subject to the
    bilateral control rule). To the extent that Bass, Polycast, and
    Medcom are at odds with the Restatement, we apply the latter.
    76
    BCE as (allegedly) part of a BCE/Teleglobe joint representation.
    Under these circumstances, we predict that the Delaware
    Supreme Court would follow the Restatement rule (as accepted
    by both the Delaware Court of Chancery and the federal District
    of Delaware Court) that Teleglobe alone cannot waive the
    privilege as to communications involving BCE.
    4.     Conclusion and Remand
    Ordering the production of documents on the privilege
    log must be predicated on a factual finding that BCE and the
    Debtors were parties to a joint representation. Because there is
    no such finding on record, we remand for further factfinding on
    this issue. On remand, that factfinding should consider § 14 of
    the Restatement, which details how a lawyer/client relationship
    arises, and our discussion in Part IV.C, supra, on the existence
    and scope of a co-client relationship.
    B.     The Effect of Funneling Documents Through
    BCE’s In-House Counsel
    The District Court held that because BCE funneled all of
    the contested documents through in-house counsel who were
    jointly representing Teleglobe, all of those documents are
    discoverable to the Debtors as part of the BCE/Teleglobe joint
    representation. This ruling applied even to documents produced
    77
    by outside counsel that did not represent Teleglobe (or the
    Debtors). As an initial matter, the District Court’s reasoning
    cannot survive our determination in section A of this Part that
    whether BCE and Teleglobe were jointly represented does not
    matter without an additional finding that the Debtors were also
    parties to that representation. Still, we examine the Special
    Master and District Court’s reasoning because it may be relevant
    on remand.
    In reaching his decision on this issue, the Special Master
    relied primarily on In re Mirant Corp., 
    326 B.R. 646
    , 651
    (Bankr. N.D. Tex. 2005). In that case, a parent company and its
    wholly owned subsidiary formally engaged the Troutman
    Sanders law firm to represent them jointly with regard to the
    sale of 20% of the subsidiary’s stock. 
    Id. at 648
    . The Court
    held that the subsidiary/debtor could obtain documents arising
    out of the joint representation despite the fact that the
    engagement letter stipulated that the parties agreed that their
    individual communications with the joint attorneys would be
    privileged against one another. 
    Id. at 652
    . That holding is off
    point here because it did not speak to whether documents
    outside of the scope of the joint representation and provided by
    outside attorneys are brought within that scope merely because
    they pass through in-house counsel who are jointly representing
    the subsidiary as well as the parent; rather, it dealt only with
    documents produced within the scope of the joint representation
    by the joint attorneys.
    78
    Here, the Eureka principle seems most apt: when BCE
    took the trouble of hiring outside counsel to provide advice only
    to it on divestiture issues, it reasonably expected that those
    communications would be privileged. Whether BCE in-house
    counsel should have refused to look at the documents because
    of their own conflicts is, under Eureka, beside the point, as is
    whether its in-house counsel had a fiduciary duty to share
    information with Teleglobe. 
    743 F.2d at
    937–38. (Not to be
    forgotten is that BCE’s in-house counsel also had a duty to keep
    its communications confidential.)
    The guiding principle of Eureka is that when an attorney
    errs by continuing to represent two clients despite their conflicts,
    the clients—who reasonably expect their communications to be
    secret—are not penalized by losing their privilege. 
    Id.
     Indeed,
    Eureka is merely one in a line of cases that hold that
    communications outside the scope of the joint representation or
    common interest remain privileged. See, e.g., CSX Transp., Inc.
    v. Lexington Ins. Co., 
    187 F.R.D. 555
    , 560 (N.D. Ill. 1999)
    (holding that documents outside the scope of the common
    interest need not be disclosed); Strategem, 153 F.R.D. at 543
    (same); Pittston Co. v. Allianz Ins. Co., 
    143 F.R.D. 66
    , 69–71
    (D.N.J. 1992) (same); Carey-Canada Inc. v. Aetna Cas. & Sur.
    Co., 
    118 F.R.D. 250
    , 2501 (D.D.C. 1987) (same).
    The District Court relied primarily on policy analysis: it
    noted that forcing BCE to choose between (1) allowing in-house
    counsel to filter the information from outside counsel while
    79
    losing the privilege, and (2) maintaining the privilege by not
    working directly with outside counsel, is “harsh.” App. at
    A0015. It stated, however, that the result was required by the
    law of the adverse-litigation exception to the joint-client
    privilege, and that BCE could have protected itself by clearly
    terminating any representation of Teleglobe by its in-house
    lawyers when it began reconsidering its funding of Teleglobe.
    The Mirant Court also engaged in policy analysis that the
    Debtors endorse:
    Even were there merit in the arguments of
    Troutman and [the parent company] TSC, the
    court would be most reluctant to deny Debtors the
    requested discovery for reasons of public policy.
    It is black-letter law that the attorney-client
    privilege is meant to foster open communications
    between attorney and client. . . . In a bankruptcy
    case, the need for investigation is far more acute
    than is any concern for attorney-client
    communications. . . . Debtors, acting as
    fiduciaries for the benefit of their creditors, are
    pursuing an investigation which is important not
    only to those who may have lost money as a result
    of Debtors’ demise. It is critical that both those
    who purchased Mirant’s (and its subsidiaries’)
    securities and the public have confidence that
    potential liability of TSC (and Troutman) has
    80
    been thoroughly explored. That Debtors sought
    chapter 11 relief less than two and one half years
    after TSC completed their divestiture is reason
    enough to raise concern that all might not have
    been right in the transactions between TSC and
    Mirant. . . . Given the short time between
    divestiture and commencement of these chapter
    11 cases and given the pre-divestiture history of
    Debtors’ problems, it is essential to the integrity
    of the chapter 11 process that no stone be left
    unturned in ensuring satisfactory completion of
    Debtors’ investigation.
    
    326 B.R. at
    654–55 (citations omitted).
    In a similar vein, the Debtors argue that BCE created and
    controlled this situation, i.e., it tried to have it both ways by
    having in-house counsel work primarily for BCE while still
    jointly representing Teleglobe. Because of its control over the
    situation, the Debtors argue, BCE should not be heard to
    complain about the legal ramification of losing its privilege
    against producing documents. They further contend that BCE
    could have obtained outside counsel for Teleglobe at any time
    and ceased its joint representation, and because it did not do so,
    it must relinquish its documents.
    As noted, the District Court here conceded that this result
    was harsh, as did the Mirant Court. Both, however, seemed to
    81
    believe that allowing the privilege to stand would make it too
    easy for parent companies to hide their wrongdoing. This truth-
    seeking rationale, however, is a problem because the privilege
    is admittedly not truth-seeking. United States v. Liebman, 
    742 F.2d 807
    , 810 (3d Cir. 1984) (“It does not advance resolution of
    the issue to argue . . . that the attorney-client privilege is an
    obstacle to the search for the truth.” (internal citations and
    quotations marks omitted)). Moreover, Delaware abrogates the
    privilege in the face of serious wrongdoing facilitated by the
    attorney through the crime/fraud exception. DEL. R. EVID.
    § 502(d)(1) (“There is no privilege under this rule . . . [i]f the
    services of the lawyer were sought or obtained to enable or aid
    anyone to commit or plan to commit what the client knew or
    reasonably should have known to be a crime or fraud.”). This
    reflects a policy choice that, absent well-founded allegations not
    only of serious wrongdoing but of serious wrongdoing
    facilitated by the attorney, the privilege should stand. Here, the
    Debtors do not appear to have alleged that BCE’s attorneys
    aided any wrongdoing. Moreover, invoking the crime-fraud
    exception requires that the plaintiff make a prima facie showing
    of evidence supporting the elements of the exception. In re
    Grand Jury Investigation, 
    445 F.3d 266
    , 274 (3d Cir. 2006).
    While that showing is not onerous, it is necessary, for “a mere
    charge of wrongdoing will [not] . . . put the privilege to flight.”
    Clark v. United States, 
    289 U.S. 1
    , 14 (1933) (Cardozo, J.). The
    adverse-litigation exception to the joint-client privilege should
    not be a back-door means of destroying the attorney-client
    privilege on the basis of alleged wrongdoing; if the Debtors had
    82
    wanted to lay to rest the privilege on those grounds, they should
    have asserted the crime-fraud exception directly and allowed the
    District Court to pass on whether they could make the required
    prima facie showing.
    In addition, Eureka counsels that it is the scope of the
    joint representation—not whether communications were shared
    with joint attorneys—that is dispositive. 
    743 F.2d at
    937–38.
    If the communications were outside the scope of the joint
    representation, then sharing them with a conflicted joint attorney
    is of no moment, even if the conflicted attorney acted
    improperly in accepting the communications. 
    Id.
     If the
    communications were within the scope, then they are
    discoverable. 
    Id. at 937
    . Either way, the fact that documents
    prepared by outside counsel were shared with in-house counsel
    does not have the significance that the District Court and Special
    Master attached to it. What we believe is significant is that, on
    remand, the District Court needs to determine whether any
    attorneys jointly represented BCE and the Debtors on a matter
    of common interest. If they did, then any documents within the
    scope of that joint representation are discoverable.
    Amicus curiae ACC fears that invoking Eureka implies
    that in-house counsel act improperly when they review
    documents from outside counsel. Not so. Here we have a
    finding of fact that BCE’s in-house counsel jointly represented
    BCE and Teleglobe on all issues relating to Teleglobe’s ultimate
    spin-off. If that finding is correct, then it was bad judgment for
    83
    BCE’s in-house attorneys to take part in outside counsel’s
    separate representation of BCE on the same issues if it still
    wanted the shield of the attorney-client privilege. We note,
    however, that the factual finding gives us pause. As we detailed
    in Part IV.F, supra, parent-subsidiary joint representations are
    typically quite narrow in scope. Still, we have not reviewed all
    of the documents that the Special Master and District Court did,
    so we can neither affirm nor vacate that finding on the record
    before us—and we need not because the Debtors’ status as third
    parties to any BCE/Teleglobe joint representation makes its
    scope irrelevant as a matter of law.
    We agree with ACC that a rule forcing parent companies
    to choose between relinquishing the privilege on one hand and
    relinquishing any control over their subsidiaries makes little
    sense. If the parent chooses to forgo the use of its in-house
    counsel on an important transaction, then it loses the advisors
    that know the most about its legal health. If it chooses to cut off
    its subsidiary, then it risks liability when the subsidiary and
    parent do not operate in tandem. Putting that choice in the
    context of this case, it appears that BCE spent some four months
    deciding what to do with Teleglobe. Over the course of Project
    X, it considered a variety of options that did not involve
    abandoning Teleglobe. Moreover, during this time it was still
    responsible for reviewing Teleglobe’s public filings. Thus for
    BCE’s in-house counsel to cut Teleglobe off would have been
    an expensive and risky proposition. Similarly, given that BCE
    was in the process of making a very serious business decision
    84
    with important legal implications, to deprive it of its in-house
    counsel simply so that those attorneys could continue to advise
    Teleglobe on other matters seems overly harsh.
    To prevent this outcome, it is important for in-house
    counsel in the first instance to be clear about the scope of
    parent-subsidiary joint representations. By properly defining the
    scope, they can leave themselves free to counsel the parent
    alone on the substance and ramifications of important
    transactions without risking giving up the privilege in
    subsequent adverse litigation.
    VI.    Potential Alternate Sustaining Grounds
    A.     The Fiduciary Exception to the Attorney-
    Client Privilege
    Before the Special Master and in supplemental briefing,
    the Debtors argue that they should be allowed access to the
    disputed documents under the fiduciary exception to the
    attorney-client privilege as articulated in Garner v.
    Wolfinbarger, 
    430 F.2d 1093
     (5th Cir. 1970). The core holding
    of Garner is as follows:
    The attorney-client privilege still has
    viability for the corporate client. The corporation
    is not barred from asserting it merely because
    those demanding information enjoy the status of
    85
    stockholders. But where the corporation is in suit
    against its stockholders on charges of acting
    inimically to stockholder interests, protection of
    those interests as well as those of the corporation
    and of the public require that the availability of
    the privilege be subject to the right of the
    stockholders to show cause why it should not be
    invoked in the particular instance.
    Garner, 430 F.2d at 1103–04. Garner thus allows shareholders
    of a corporation to invade the corporation’s privilege in order to
    prove fiduciary breaches by those in control of the corporation
    upon showing good cause.
    As the Debtors note, while the Delaware Supreme Court
    has never adopted Garner, the Court of Chancery has adopted
    and applied it in numerous decisions. Indeed, Vice Chancellor
    Lamb wrote that “Delaware courts follow the approach outlined
    in Garner.” Grimes v. DSC Comm. Corp., 
    724 A.2d 561
    , 568
    (Del. Ch. 1998) (citing Deutsch v. Cogan, 
    580 A.2d 100
    , 105
    (Del. Ch. 1990) (“Delaware courts have consistently followed
    Garner.”)).
    In Deutsch, the Court of Chancery extended Garner to a
    situation in which cashed-out minority shareholders of a
    subsidiary sought to abrogate the attorney-client privilege of the
    parent company’s controlling shareholder in a dispute over a
    merger transaction that the minority shareholders contended was
    86
    not fundamentally fair. 
    580 A.2d at
    102–03. The Court held
    that Garner applied by analogy because the parent’s controlling
    shareholder, as the entity in fact controlling the subsidiary, owed
    the minority shareholders fiduciary duties. 
    Id. at 107
    .
    Therefore, in a dispute over compliance with those duties, the
    minority shareholders could—upon showing good
    cause—overcome the privilege with regard to documents related
    to the challenged transaction. 
    Id. at 108
    .
    The Debtors’ argument here is similar: because BCE
    controlled the Debtors while they were insolvent, it owed
    fiduciary duties to the Debtors of which their creditors (not
    BCE) were the primary beneficiaries. See generally N. Am.
    Catholic Programming Found., __ A.2d at ___, 
    2007 WL 1453705
    , at *7. Thus, in this dispute, in which the Debtors are
    asserting a breach of those duties for the benefit of their
    creditors, the Debtors should be able to put aside the privilege
    upon showing good cause. It is possible that Delaware courts
    would extend the Garner fiduciary exception to a situation like
    this one. The key, however, is insolvency. If the Debtors were
    not insolvent (or in that hazy “zone of insolvency,” see supra
    note 9) at the time of the otherwise privileged communications,
    then BCE was the only beneficiary of the Debtors’ success, and
    it could not, therefore, breach its fiduciary duty to itself.
    Whether a corporation is insolvent, and when it becomes
    so, are an issues of fact. Trenwick, 
    906 A.2d at 195
    . Under
    Delaware law, a corporation is insolvent if it has: “1) a
    87
    deficiency of assets below liabilities with no reasonable prospect
    that the business can be successfully continued in the face
    thereof, or 2) an inability to meet maturing obligations as they
    fall due in the ordinary course of business.” Prod. Res. Group,
    LLC v. NCT Group, Inc., 
    863 A.2d 772
    , 782 (Del. Ch. 2004)
    (Strine, V.C.) (internal citations and quotation marks omitted).
    Here, both parties seem to agree that the Debtors were all deeply
    in debt with no significant revenue stream other than BCE’s
    funding. The dates on which each Debtor became insolvent,
    however, are issues of fact that we cannot resolve here.
    In addition, the Debtors’ argument appears to have a
    significant deficiency: they must have a colorable claim of
    breach of fiduciary duty to show “good cause.” Garner, 430
    F.2d at 1104. Even if BCE owed the Debtors and their creditors
    fiduciary duties, it seems a stretch to argue that BCE’s decision
    not to fund Teleglobe implicated those duties. A fiduciary
    ordinarily has the obligation (protected by the business
    judgment rule) to manage the affairs of a corporation in such a
    way as to maximize its economic value; it does not have a duty
    to guarantee or bail out a corporate family member when it loses
    money. Trenwick, 
    906 A.2d at 205
    . As Vice Chancellor Strine
    noted in Trenwick, insolvency does not render a corporation’s
    fiduciaries guarantors of that corporation’s success; rather, it
    merely expands the universe of people with standing to assert a
    beneficial interest in the fiduciaries’ obligation to maximize the
    88
    value of the corporation.36 
    Id.
     Whether BCE would continue to
    infuse Teleglobe and the Debtors with funding seems, at least at
    first glance, entirely BCE’s decision. Still, we do not have the
    entire record before us, and so we leave this issue for the District
    Court to resolve in the first instance.
    Mopping up, BCE advances seven arguments against
    applying Garner in this situation, most of which are unavailing.
    First, it argues that Garner does not apply to work product. This
    is correct, but as we do not know how many of the 800 different
    documents currently in dispute contain work product, we must
    leave this issue for the District Court to resolve on remand.
    Second, BCE (the appellant) argues that the Debtors (the
    appellees) have abandoned the Garner argument. The cases it
    cites, however, are off the mark because they address the
    appellant’s obligation to raise all grounds for reversal. See
    Simmons v. City of Philadelphia, 
    947 F.2d 1042
    , 1066 (3d Cir.
    1991) (Opinion of Becker, J., announcing the judgment of the
    Court); Inst. for Scientific Info., Inc. v. Gordon & Breach, Sci.
    Publishers, Inc., 
    931 F.2d 1002
    , 1011 (3d Cir. 1991). It is
    36
    In Trenwick, the Vice Chancellor put to rest the notion that
    there is such a thing as a cause of action for so-called
    “deepening insolvency” in Delaware law. 
    906 A.2d at 205
    .
    This effectively prevents extending our holding in Official
    Comm. of Unsecured Creditors v. R.F. Lafferty & Co., 
    267 F.3d 340
    , 347 (3d Cir. 2001), in which we decided that the cause of
    action exists in Pennsylvania, to Delaware cases (and supersedes
    those few Delaware District and Bankruptcy Court cases that
    have done so).
    89
    firmly established that we may affirm on any ground supported
    by the record, so the Debtors’ failure to raise the issue does not
    waive it. Azubuko v. Royal, 
    443 F.3d 302
    , 303 (3d Cir. 2006).
    Moreover, the issue has yet to be addressed by the District
    Court, and it remains open on remand.
    Third and fourth, BCE argues that Garner has been
    rejected by Canadian courts and never adopted by our Court. As
    a matter of federal common law, it is correct that we have not
    always applied Garner, see Wachtel v. Health Net, Inc., 
    482 F.3d 225
    , 233 (3d Cir. 2007), but neither party argues that
    federal common law governs this dispute.37 As to the Canadian
    law argument, we doubt that Canadian law would apply to this
    issue, as the Debtors are Delaware corporations.38 Under the
    internal affairs doctrine, anyone controlling a Delaware
    corporation is subject to Delaware law on fiduciary obligations
    to the corporation and other relevant stakeholders. See In re
    Topps Co. S’holders Litig., ___ A.2d ___, 
    2007 WL 1491451
    ,
    at *7 (Del. Ch. 2007) (Strine, V.C.) (explaining that the law of
    fiduciary obligations is one of the most important ways a state
    regulates a corporation’s internal affairs); RESTATEMENT
    37
    Federal common law does not apply to disputes about
    corporations’ internal affairs. VantagePoint Venture Partners
    1996 v. Examen, Inc., 
    871 A.2d 1108
    , 1113 (Del. 2005) (“It is
    now well established that only the law of the state of
    incorporation governs and determines issues relating to a
    corporation’s internal affairs.”).
    38
    This is the only issue on which BCE argues that there is a
    true conflict of law, see Part III, 
    supra. 90
    (SECOND) OF CONFLICTS OF LAWS § 306. Moreover, if
    Delaware law favors admission of the evidence, then BCE must
    show some “special reason” why that should not be given effect.
    Id. § 139(2); see also Carlton Invs., Inc. v. TLC Beatrice Int’l
    Holdings, Inc., No. C.A. 13950, 
    1996 WL 33167792
    , at *2 (Del.
    Ch. Sept. 27, 1996). Still, because we ultimately conclude that
    we cannot apply Garner here without knowing when the
    Debtors became insolvent, we will not conduct a full-scale
    choice-of-law analysis.
    Fifth and sixth, BCE argues that Garner cannot be
    extended to this situation because (1) BCE owed the Debtors no
    fiduciary duties, and (2) Garner does not permit subsidiaries to
    invade the privilege of indirect corporate parents. The answer
    to both arguments is that BCE, as the ultimate owner of more
    than half (and, indeed, all) of the Debtors’ voting power, owed
    them the duties of care and loyalty. See Weinstein Enters. v.
    Orloff, 
    870 A.2d 499
    , 507 (Del. 2005). If the Debtors were
    solvent, then all duties flowed back up to BCE as the only party
    with a legitimate interest in the Debtors’ success. If that were
    the case, then BCE is correct that it effectively owed the Debtors
    no duties. However, if the Debtors were insolvent, then their
    creditors also had a legitimate interest in their success. See N.
    Am. Catholic Programming Found., ___ A.2d at ___, 
    2007 WL 1453705
    , at *7. With multiple stakeholders, BCE’s duties of
    care and loyalty would come into play in the same way that the
    directors’ duties did in Garner, and its attorney-client privilege
    could be set aside by showing good cause.
    91
    Finally, BCE argues that the Debtors cannot show good
    cause. As BCE concedes in the next breath, however, it is not
    for us to determine whether they can show good cause in the
    first instance; so we leave the issue open on remand.
    B.      Affirming as a Discovery Sanction
    The Debtors urge us to affirm the District Court’s order
    as a sanction for BCE’s penchant for designating too many
    documents as privileged. We cannot do so at this time for the
    simple reason that the District Court did not impose such a
    sanction. To be sure, both the Special Master and District Court
    expressed displeasure with BCE’s litigation conduct, but neither
    expressly penalized that behavior, and so we have no sanction
    order to review. We do note that preventing a party from
    asserting the attorney-client privilege is a legitimate sanction for
    abusing the discovery process, and we do not foreclose that
    remedy on remand. Disclosure is a serious sanction, but one
    that may be imposed only if the District Court finds bad faith,
    wilfulness, or fault. See Am. Nat’l Bank & Trust Co. of Chicago
    v. Equitable Life Assur. Soc’y of U.S., 
    406 F.3d 867
    , 877–80
    (7th Cir. 2005).
    VII.   Conclusion
    We hold that the District Court may only compel BCE to
    produce disputed documents because of the adverse-litigation
    exception to the co-client privilege, see Part IV.D, supra, if it
    92
    finds that BCE and the Debtors were jointly represented by the
    same attorneys on a matter of common interest that is the
    subject-matter of those documents. Finding that BCE and
    Teleglobe were jointly represented is not enough, as Teleglobe
    cannot unilaterally waive the co-client privilege that attaches to
    documents that involve BCE and were created in the course of
    the joint representation. Moreover, BCE has not waived the
    argument, and it is not in some “community of interest” with the
    Debtors as a matter of law. In addition, that documents prepared
    by outside counsel were funneled through in-house counsel for
    both BCE and Teleglobe is of no moment. Following Eureka,
    what matters is the scope of any joint representation: documents
    within the scope are discoverable; documents outside it are not,
    irrespective of whether they were improperly funneled through
    joint attorneys.
    On remand, then, the primary issue is whether any
    attorneys jointly represented BCE and the Debtors on a matter
    of common interest. Also open on remand are the issues of
    discovery sanctions and whether the Garner fiduciary
    exception—currently extant in Delaware— applies in this case.
    Because of the need to resolve this privilege dispute
    efficiently so that the underlying litigation can proceed, this
    panel of our Court will continue to review any additional
    privilege-related appeals.
