Appellate Practice Attorney serving New York, NY
You are required to provide all documents you have which are requested in a valid subpoena or other valid legal discovery device, or which your client directs you to produce. In many states (don't know about TN specifically), third parties can receive some compensation for expenses they incur in complying with a discovery request (e.g. copying costs), but it usually is a minimal amount.
Absent a valid subpoena, or authorization from your client, you are not required to produce anything. Indeed, you have a duty to your client to safeguard his privacy (although, for purposes of the joint tax returns, the wife could be considered your client) until and unless you are compelled to disclose information by legal process.
If a subpoena is served on you, you or your client can seek to quash the subpoena if you believe that it is improper. My advice would be not to litigate the validity of the subpoena, since that would cost you money and time, but rather to leave it to the husband to chalenge the subpoena if he wishes to. If he does, the Court will likely order you not to respond to the subpoena until its validity is determined.
Obviously, you cannot produce any documents which are not in your possession or control. Just produce what you can.
