In that case, your FIL can just sign himself out. If no court ordered a guardianship, he can take control of his affairs at his own discretion UNLESS someone, an “interested party” petitions the court to declare him incompetent.

That seems strange. The trustee had to have 3 physicians attest, in writing, to his incompetence. If he could have simply signed himself out, he would have done so months ago. Because, he has vociferously demanded to leave.

That's why he's in a lock down unit. He kept leaving, but they brought him back.
