(a) If, during the pendency of an initial petition for conservatorship, it appears that the respondent is in need of a protective order to protect the respondent against waste or dissipation of funds or property, or to obtain funds that are needed for the immediate support, care, and welfare of the respondent or persons entitled to be supported by the respondent, and the respondent is not capable of protecting the respondent's funds or property or obtaining the funds that are needed to support the respondent or persons whom the respondent is required to support, the petitioner may request the appointment of a temporary conservator to authorize the protection or to obtain the necessary funds. The request must state the reasons and factual basis for the request. The petitioner shall immediately file the request with the court and serve copies on the respondent and the respondent's attorney and other persons as ordered by the court. The court shall appoint an attorney for a respondent who is unrepresented to be at the hearing and conduct a hearing within 72 hours after the filing.
(b) If the court determines that a temporary conservator should be appointed, it shall make the appointment and grant to the temporary conservator only the authority that is least restrictive upon the liberty of the respondent and that enables the temporary conservator to provide the protection or authority necessary to protect the respondent from waste or dissipation of funds or property or to obtain the funds necessary for support.
(c) The temporary conservatorship expires at the time of the appointment of a full or partial conservator or on the dismissal of the petition for conservatorship.
