Final answer:
A breach of duty in a fiduciary relationship without fraudulent intent is known as a breach of fiduciary duty, which can arise from conflicts of interest, misappropriation of funds, abuse of authority, or negligence.
Step-by-step explanation:
When a breach of duty occurs in a fiduciary relationship without fraudulent intent, giving an advantage to one party, it is often referred to as a breach of fiduciary duty.
A fiduciary is someone who has undertaken to act for and on behalf of another in a particular matter in circumstances which give rise to a relationship of trust and confidence. Examples of fiduciary relationships include those between lawyers and clients, trustees and beneficiaries, and corporate directors and shareholders. Even without fraudulent intent, the breach can lead to legal consequences because of the expectation of loyalty and care that fiduciaries owe to the principals they serve. A breach of fiduciary duty might arise from conflicts of interest, misappropriation of funds, abuse of authority, or negligence in performing fiduciary responsibilities.
