Forms of leases are procurable at the various law stationers. In these leases blanks are left for the insertion of particular clauses. A few of the clauses found in leases may be briefly discussed:

There is usually a covenant on the part of the tenant that he will not assign his lease, nor make any alterations in the property without first obtaining the landlord's written consent. The tenant is usually required to observe all requirements of law and ordinance and all regillations of the municipal departments. It is a prudent thing for the landlord to insert a clause giving him permission to visit and inspect the premises at reasonable times. If such permission be not provided for, the landlord has no right to enter upon the property without becoming a trespasser.

It is proper to insert a clause specifying the use to which the premises shall be put, and prohibiting the use of the property for purposes not desired.
