Section 1 defines the new statutory duty of care, using familiar words drawn from case law. A trustee must show such care and skill as is reasonable in the circumstances of the case, taking into account any special knowledge, experience or professional status he or she might possess or claim. So there is flexibility built in here and a higher standard may be demanded of an “expert” acting as trustee than a person of “ordinary” talents, depending on the context. In determining what constitutes reasonable care, the nature, composition and purposes of the trust will also be taken into consideration.
