Q: Dear Ethics Lawyer, Occasionally, we have clients who request that we send them their files, either because the matter is completed, or because for one reason or another they are moving their representation to another law firm. I’ve also discovered that we are storing a massive amount of closed client files, at considerable cost, and I’d like to return as many of these files to clients as possible (whether we can destroy old files for which we cannot locate the client is a question for another day).

In thinking about these things, however, I am stuck on questions relating to what parts of the client matter files belong to and must be returned to clients, and what parts belong to us? Model Rules 1.15 and 1.16 do not appear to provide specific guidance.
