Who is his guardian? Is that the trustee?
If yes the trustee CAN make that decision. We had a similar situation with an aunt. I was the conservator—I was in charge of the money. My wife was the guardian, responsible for her well being. She had the sole legal authority to have her committed, or released.
There are a ton of questions to ask....but not relevant for this forum.
There is no guardianship in this case. It’s just the trustee making pertinent decisions.
I should say, it’s the trustee making pertinent decisions (as prescribed by my FIL in the original trust).
