Duty of care (business associations)

In United States corporation and business association law (particularly Delaware law and the Revised Model Business Corporation Act), a duty of care is part of the fiduciary duty owed to a corporation by its directors. The other aspects of fiduciary duty are a director's duty of loyalty and (possibly) duty of good faith.

Put simply, a director owes a duty to exercise good business judgment and to use ordinary care and prudence in the operation of the business. They must discharge their actions in good faith and in the best interest of the corporation, exercising the care an ordinary person would use under similar circumstances.

Directors' decisions are typically protected under the business judgment rule, unless they breach one of these duties or unless the decision constitutes waste. A breach of fiduciary duty will typically remove a director's decision from business judgment protection and require that the director show entire fairness.
