 Under Section 5 , trustees are required to obtain " proper advice " before investing , unless the circumstances mean that it is inappropriate or unnecessary to do so . " Proper advice " is defined in Section 5 ( 4 ) as " advice of a person who is reasonably believed by the trustee to be qualified to give it by his ability in and practical experience of financial and other matters relating to the proposed investment " . This is an objective test , and as with much of Section 4 , is almost identical to the test laid out in the 1961 Act . The advice must be sought before the exercise of any investment power , and is also required if the trustee wishes to change where and how the trust is invested .
