What is the term for a person or organization that has temporary possession of someone else's personal property?

The term for a person or organization that has temporary possession of someone else's personal property is a bailee. A bailee is entrusted with the property for a specific purpose, such as storage, repair, or maintenance, and this arrangement involves an agreement, which can be formal or informal. The bailee is expected to take reasonable care of the property while it is in their possession and return it to the owner, known as the bailor, once the purpose has been fulfilled.

In this context, the role of the bailee emphasizes the responsibility they hold for the property, distinguishing them from other parties, such as a lessee, who is typically renting property, or a trustee, who manages property for the benefit of another party. Understanding this role is crucial for anyone involved in personal property agreements, as it outlines the obligations and liabilities that arise from the possession of another's property.
