Can an in-house lawyer for one corporate subsidiary also provide legal services to another subsidiary of the same parent?

Plain-English summary

A lawyer works in the legal department of insurance company A, which is several layers down a corporate family (A is a subsidiary of B, under a holding company, under a parent). The parent recently acquired company X, an unrelated business, and asks the lawyer to provide legal services to X on matters wholly unrelated to A. The committee is asked whether the lawyer may represent X.

The opinion confirms that corporations may employ in-house lawyers (Rule 1.0(c) and Comment 3 treat a corporate law department as a "firm"; Rule 1.13(a) addresses representing an organization through its constituents; 705 ILCS 220/5 permits a corporation to employ its own attorneys), and that in-house counsel may represent a parent and multiple affiliates (citing Restatement Section 96(h), Teleglobe Communications Corp. v. BCE, and NYC Bar Formal Opinion 2008-02). It then flags the recurring hard issues: identifying the client, conflicts, and confidentiality. On client identity, the opinion observes the rules give no single test and suggests that treating subsidiaries as distinct clients is the better practice. On conflicts, it directs the lawyer to apply Rule 1.7 when serving a related entity that is not the direct employer, and lists options if interests conflict: obtaining the parent's and subsidiary's consent under 1.7(b), advance waivers, limiting scope, or retaining outside counsel. On confidentiality, it discusses Rule 1.6, noting that strict subsidiary-to-parent confidentiality is often unworkable in a corporate family (Teleglobe held intra-group sharing does not waive privilege) and that consent, implied authorization, or the 1.6(b) exceptions may apply, while flagging harder cases like subsidiary insolvency or divestiture.

Applying this to the inquiry, the opinion stresses that none of these problems are actually present: company X's business is wholly unrelated to company A, no conflict or adversity is identified, and no confidential information is being shared. The committee therefore concludes the lawyer may represent subsidiaries A and X in wholly unrelated matters, and declines to speculate about concerns not raised by the facts.

In practice

Under this opinion, an in-house lawyer may take on legal work for another subsidiary of the same parent; the opinion holds the representation here is permitted because the two subsidiaries are in unrelated businesses with no identified conflict and no shared confidences. The opinion holds that where interests do conflict, the lawyer should apply Rule 1.7 and may obtain consent from the parent and subsidiary, use advance waivers, limit scope, or retain outside counsel, and that confidentiality questions under Rule 1.6 turn on consent, implied authorization within the corporate family, or the 1.6(b) exceptions. It identifies client identification, conflicts, and confidentiality as the areas to watch, while declining to opine on facts not presented.

Common questions

Q: Can our in-house counsel handle work for a sister company under the same parent?

A: Yes. The opinion concludes an in-house lawyer may represent multiple subsidiaries of the same parent, and finds the representation here permitted because the businesses are unrelated with no conflict or shared confidences.

Q: What should in-house counsel watch for across a corporate family?

A: The opinion identifies three areas: who the client is (it suggests treating subsidiaries as distinct clients), conflicts under Rule 1.7, and confidentiality under Rule 1.6.

Q: How can a conflict between affiliated entities be addressed?

A: The opinion lists obtaining the parent's and subsidiary's informed consent under Rule 1.7(b), using advance conflict waivers, limiting the scope of the representation, or retaining outside counsel.

Background and rules framework

The opinion interprets Illinois Rule of Professional Conduct 1.13 (organization as client), Rule 1.7 (conflicts of interest), Rule 1.6 (confidentiality), and Rule 1.0(c) (the corporate law department as a "firm"), against the statutory authorization for corporate in-house counsel in 705 ILCS 220/5. These correspond to Model Rules 1.13, 1.7, 1.6, and 1.0.
