There are various types of letting, depending on what is involved: goods, works or services. In the letting of goods, one of the parties (the lessor) is obliged to give the other party (the lessee) possession or use of goods for a set time and at a fixed price. In the letting of work or services, one of the parties (the lessor) is obligated to carry out work or render the other party (the lessee) a service for a set price.
