The essential parts of a lease are the premises, term, amount of rent and manner of payment, and the covenants and conditions agreed upon. The agreement is made between two or more parties known as lessor and lessee (or landlord and tenant). A written lease will usually be dated and signed by both parties. Seals, witnessing and acknowledgments are sometimes added. There are a number of lease forms in general use. These forms vary from the very short monthly letting agreement to the lengthy agreement drawn to contain provisions for an important long-term lease. There is no one form that will fit every case - a lease must be drawn so that it expresses the intended agreement between landlord and tenant. Reference to the forms in the appendix will, however, illustrate some conditions that have been found of value.
