Which trustee duty requires acting in good faith and solely in the beneficiaries' best interests?

• A. TRUSTEE LOYALTY
• B. TRUSTEE SELF-DEALING
• C. PRUDENT INVESTOR RULE
• D. TRUSTEE PRUDENCE

Answer: (A)

Loyalty is the trustee’s fundamental obligation. A trustee must act as a fiduciary, putting the beneficiaries’ interests above the trustee’s own and doing so in good faith. The duty of loyalty requires decisions to be made solely for the beneficiaries’ benefit, free from conflicts of interest or self-dealing. That direct pairing of acting in good faith with pursuing only beneficiaries’ best interests is exactly what loyalty embodies. The other concepts touch on related ideas but aren’t the core duty asked about here. Self-dealing describes prohibited conduct under the loyalty obligation, not the duty’s name itself. The prudent investor rule governs how investments are chosen and managed, emphasizing prudent risk and diversification rather than the broader obligation to serve beneficiaries’ interests. A term like “trustee prudence” isn’t the standard label for this duty.
