What kind of bailment involves no compensation to the bailee?

Gratuitous bailment refers to a type of bailment in which the bailee does not receive any compensation for holding or caring for the bailor's property. In this arrangement, the bailee agrees to take possession of the property solely out of goodwill or for a non-monetary benefit to the bailor. An example of gratuitous bailment would be when a friend lends a book to another friend without any expectation of payment or reward.

The other types of bailments generally involve some form of compensation or benefit to the bailee. Mutual bailment involves both parties getting something in return—usually seen in services exchanged for payment. Commercial bailment includes transactions where the bailee is paid for their services, such as in storage or transportation of goods. Voluntary bailment, while it may involve no obligation, implies that there is often an expectation of a benefit to one or both parties involved, not solely without compensation. Thus, gratuitous bailment clearly stands out as the correct choice, as it explicitly defines the scenario where the bailee is not compensated.
