Is it unethical for an attorney to comply with a letter request from the Internal Revenue Service for information concerning a client's personal injury lawsuit which had been settled, such request being for the following information:
1. Who was the claim against and what were the reasons for it being filed?
2. What was the final amount of settlement awarded to Mrs. __________?
3. What was the distribution of the claim - how much were the doctor bills, lawyers' fees, etc.?
Where the attorney has been unable to obtain instructions from the client as to how to proceed.
