Final answer:
A seller's agent's fiduciary duty of confidentiality might prevent the disclosure of a death or felony that occurred in a home. The requirements vary by state, with some having non-disclosure statutes that do not require disclosure unless explicitly asked by the buyer.
Step-by-step explanation:
The fiduciary duty that might require a seller's agent not to disclose if a death or felony occurred in a home is primarily based on the principle of confidentiality. This duty is part of the broader category of fiduciary responsibilities that a seller's agent owes to their client. In the context of real estate, these duties typically include loyalty, obedience, disclosure, confidentiality, reasonable care, and accounting. However, the specific requirements regarding disclosure of deaths or felonies vary from state to state. Some states have 'non-disclosure' statutes that do not require the seller to disclose such events, as they are considered to not materially affect the value or desirability of the property. On the other hand, in some places, if the buyer explicitly asks about such occurrences, the seller might be legally obligated to provide truthful information.
