§2233.  Instructions

A.  A trustee, a beneficiary, or a settlor in an ordinary or a summary proceeding may apply to the proper court for instructions concerning the trust instrument, the interpretation of the instrument, or the administration of the trust.  An order of a proper court issued pursuant to such an application shall be full authority to act in accordance thereunder, and a trustee shall be fully protected from all claims of any person who has or who may subsequently acquire an interest in the trust property.  

B.  A trustee may apply for instructions in ex parte proceedings.  The order issued therein will protect a third party relying on the order, but will not exonerate a trustee from liability to a settlor or a beneficiary.
