Thanks, all. This is helpful.
Makbo, I am involved because the trustee has asked for my opinion on this. Otherwise, I would agree that this is up to the trustee and her attorney.
My initial opinion---given to the trustee before this issue came up---is that they do a formal accounting. There are adverse parties involved, and some of the beneficiaries have already raised questions about the level of expenditures. The attorney does not feel an accounting is needed and they will not be doing one.
Discussing this with the attorney is not an option. He does not respond to my phone or email messages. My only communication with him is through the trustee.
Dennis, I think you are right. I will ask the trustee to remind the attorney he would be providing adverse parties with SSN's. I will offer to provide a masked copy of the returns in lieu of what they have now. And I will stop worrying about it.
