Under which circumstance can a funeral director disclose client information?

The correct circumstance under which a funeral director can disclose client information is during legal proceedings or investigations, which aligns with the answer choice stating "only under court orders or legal investigations." This reflects legal and ethical standards that protect the confidentiality of client information in the funeral service profession.

When a funeral director is issued a court order or is involved in a legal investigation, they are legally obligated to provide the requested information. This is essential to uphold the rule of law and ensure that any potential legal matters are handled appropriately. Consequently, protecting client privacy is critical except in situations where compliance with legal requests is required.

The other options suggest circumstances under which disclosure would not adhere to the confidentiality principles mandated by law and ethical guidelines governing the profession. For instance, disclosing information whenever a funeral director feels like it, at networking events for business promotion, or without restrictions for educational purposes are all scenarios that could lead to breaches of client confidentiality and violate legal standards.
