Who is termed the next of kin that delivers the personal effects of the deceased to the funeral director?

The term "bailor" is appropriate in this context as it refers to the individual who voluntarily delivers personal property to another party, known as the bailee (in this case, the funeral director). The bailor retains ownership of the property while allowing the bailee to possess it temporarily. When a next of kin or a close relative brings the deceased's personal effects to the funeral director, they act as the bailor, trusting the funeral director to manage those belongings appropriately during the funeral process.

An executor is typically named in a will and is responsible for carrying out the wishes of the deceased, particularly concerning estate matters. A beneficiary is someone who stands to gain from the deceased's estate, being a person or entity designated to receive benefits or assets. A guardian generally refers to someone who is appointed to take care of a minor or an individual who cannot take care of themselves. None of these roles involve the act of delivering personal effects in the same way that a bailor does in this situation.
