Bailor

n. one who delivers goods or entrusts property to another

Bailment describes a legal relationship in common law where physical possession of personal property (chattels) is transferred from one person (the 'bailor') to another person (the 'bailee') who subsequently holds possession of the property. However, it is distinguished from a contract of sale or a gift of property, as it only involves the transfer of possession and not its ownership. In order to create a bailment, the bailee must both intend to possess, and actually physically possess, the bailable chattel.
