Da-Keen is the trustee of a trust that was established by his parents to pay his children’s college tuition. One of his children is going to Princeton, where the tuition is more than $50,000. Another child is attending a state university, where the tuition is one-tenth of Princeton’s. He is paying both of these tuition bills. In addition, he has used trust assets to buy bonds issued by Harvard, the college he attended. Has Da-Keen violated his fiduciary duty?
