And who's going to express to counsel what you wanted when you can't do that, so that aforementioned counsel may effectively represent your interests?
That is to be determined by the counsel unencumbered by any split loyalty. Here is Florida Law illustrating that concept.
744.331 Procedures to determine incapacity.--
(2) ATTORNEY FOR THE ALLEGED INCAPACITATED PERSON.--
(a) The court shall appoint an attorney for each person alleged to be incapacitated in all cases involving a petition for adjudication of incapacity. The alleged incapacitated person may substitute her or his own attorney for the attorney appointed by the court.
(b) Any attorney representing an alleged incapacitated person may not serve as guardian of the alleged incapacitated person or as counsel for the guardian of the alleged incapacitated person or the petitioner.
How does the attorney represent the wishes of incapacited person in this situation? What is his purpose?
