(a) A court shall appoint a temporary guardian, with limited powers as the circumstances of the case require, if the court:
(1) is presented with substantial evidence that a person may be an incapacitated person; and
(2) has probable cause to believe that the person, the person's estate, or both require the immediate appointment of a guardian.
(b) The person for whom a temporary guardian is appointed under this chapter retains all rights and powers that are not specifically granted to the person's temporary guardian by court order.
