In Pa. B. Ass’n Comm. on Legal Ethics & Prof. Responsibility Formal Op. No. 2007-100 (2007), the committee in a thoughtful opinion addressed the complex issues of locating, finding, and giving to a client its “file” when e-documents, e-mail, and other digital data is involved.  Unfortunately, the opinion is only available for members of that state’s bar, or on Westlaw, at 2007 WL 1170779.  The opinion contains some useful language that lawyers might want to consider in their engagement letters to avoid later disputes about how much work the lawyer must engage in to find e-mail and other digital information if the client requests its file.
