Every conservator must account to the court for his administration of the trust annually and upon his resignation or removal, and at other times as the court may direct. On termination of the protected person's minority or disability a conservator shall account to the court. Subject to appeal within the same time permitted, an order, made upon notice and hearing, allowing an intermediate account of a conservator, adjudicates as to his liabilities concerning the matters shown in connection therewith and an order, made upon notice and hearing, allowing a final account adjudicates as to all unsettled liabilities of the conservator to the protected person or his successors relating to the conservatorship concerning the matters shown. In connection with any account, the court may require a conservator to submit to a physical check of the estate in his control, to be made in any manner the court may specify.
