(a) General rule.--Except as otherwise provided by the governing instrument, a fiduciary shall invest and manage property held in a trust in accordance with the provisions of this chapter.

(b) Exception.--Where the instrument establishing a trust contains a restriction on the fiduciary's power of investment and the court having jurisdiction over the trust finds that adherence to the restriction is impractical or that the existing or reasonably foreseeable economic conditions are so far different from those prevailing at the creation of the trust that adherence to the restriction might deprive the respective beneficiaries of income and principal of the full benefits the testator or settlor intended them to enjoy, the court may release the fiduciary from the restriction to the extent and on conditions, if any, as the court may deem appropriate.

(c) Court direction.--A fiduciary appointed by the court and not acting under a trust instrument, in addition to or in place of the investments authorized by this chapter, may make, and retain without liability for resulting loss, investments as the court, upon petition of the fiduciary or of any party in interest, after notice as it shall direct, aided by the report of a master if necessary, shall authorize or direct, subject only to the conditions and limitations as shall be fixed by the court in the decree authorizing or directing the investment.
