A recent Illinois State Bar Association ethics opinion (non-binding) advised that although an in-house lawyer at one subsidiary may also do work for another subsidiary, attorneys need to be mindful of the possibility for conflicts of interest and confidentiality issues to arise, and take steps to deal with them if they do.  See ISBA Professional Conduct Advisory Opinion, No. 17-05 (May 2017).  In the opinion, the committee said it was acceptable for an attorney at one subsidiary to perform work for another subsidiary within the corporate family.  But the committee noted that its opinion was limited to the factual situation the in-house lawyer identified, which did not involve “conflict or adversity” between the subsidiaries, and there was no suggestion that confidential information would be shared.  The Bar Association also noted that current authority supports the position that an in-house lawyer may represent a corporate parent along with multiple subsidiaries of that parent.  As part of the opinion, the committee explained that although intra-family representation presents many “problematic” issues, the Illinois Rules of Professional Conduct do not specifically address that type of representation.  The Bar Association suggested that the issues of biggest concern are client identity, conflicts of interest, and preserving client confidences, and observed that “there is no one size fits all test for identifying the client” when in-house counsel works on behalf of multiple entities within a corporate family.  Therefore, in-house attorneys should consider obtaining advance conflict waivers from the entities they are performing work for, and if they have not, if interests of different entities the attorney is performing work appear to conflict, an in-house lawyer should get consent to the representation from all entities at that time.
