Before exercising any power of investment, whether arising under this Part or otherwise, a trustee must (unless the exception applies) obtain and consider proper advice about the way in which, having regard to the standard investment criteria, the power should be exercised.

When reviewing the investments of the trust, a trustee must (unless the exception applies) obtain and consider proper advice about whether, having regard to the standard investment criteria, the investments should be varied.

The exception is that a trustee need not obtain such advice if he reasonably concludes that in all the circumstances it is unnecessary or inappropriate to do so.

Proper advice is the 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.
