Q: Dear Ethics Lawyer, I represented a closely-held LLC in the sale of real estate. A story broke yesterday that the LLC’s principal is being investigated for various alleged frauds and tax evasion. Now, an IRS agent has made an unannounced visit wanting to talk to me about the transaction I was involved in, and asking to review at least the non-privileged information in our file. What should I do? What if, instead, I was served with a confidential grand jury subpoena that instructs me not to inform anyone about it?
