If a person grants a license to another to come on his land, he owes no duty to him except the negative one of not wantonly injuring or exposing him to danger. Merchants invite the public into their stores to buy wares, but those who accompany them without any intention of purchasing are not invitees, they are mere licensees. The duty of the storekeeper to one who enters his premises by mere license is not to keep the premises in a non-hazardous state, but only to abstain from acts willfully injurious to him.

Lease.—A lease is for the use of land, usually for a few years or shorter period. The lessor is more generally known as the landlord, and the lessee as the tenant. The lease may be oral, though the better way is to put the agreement in writing. If it be for a house or other building the lessee should insist on this, otherwise he would fare much worse should the building be destroyed by fire. Doubtless many do not know that, unless the lessee makes a specific agreement relieving himself, he is liable for the rent of a building, just the same if it is burned down as if he were still the occupier. This is the common law, which has been changed in some states by statute.

If the lease is for more than a year, or other short period, the Statute of Frauds, so called, requires that it must be in writing. If the time be less, a verbal lease may be made, even though the lessee does not take immediate possession of the premises. If on the other hand, it exceeds the statutory period, it is not absolutely void, but continues during the joint wills of both parties, and may therefore cease at the will of either party. If the landlord wishes to terminate it, he must give the tenant notice to quit; should he disregard the law and take immediate possession he would be a trespasser.

When the terms of a lease are in doubt, they are construed in favor of the tenant. A lease to a specified day continues during the whole of it, though custom or statute may prescribe a different rule. A term may also continue during the option of either of the parties to be ended on notice by the party exercising the option.

The most usual agreements or covenants in a lease are on the part of the lessor for quiet enjoyment, which secures the tenant against any hindrance or disturbance of his possession and enjoyment of the premises from persons deriving their title from the landlord, or from any one else who claims to be the owner. Also against all encumbrances, in other words, that no one has any easements or other rights in the premises. The landlord also usually agrees to repair, and often to renew the lease, and the lessee to pay rent, to insure and not to assign or underlet, without the landlord's consent. The parties may of course agree to do any other lawful thing, for example, sometimes the tenant agrees to make repairs, to reside in the premises, not to engage in some kinds of business, to cultivate the land, if the lease be of a farm, in a specified way. Again though an oral lease for a term of years at a stated annual rent may not fulfill the requirement of the Statute of Frauds, the parties may conform to it and thus create a tenancy in fact from which the law will imply a leasing from year to year. If therefore the tenant with the acquiescence of the landlord continues in possession for several months after the expiration of the original term, a tenancy for another year will be created with a corresponding liability on the part of the tenant for a full year's rent. And the measure and extent of the tenant's liability would be the same, whether his continued occupancy related to the original lease, or to a subsequent one just like it, made as the first was soon to expire.

The definite period for which a lease is given is called a term. If a lease is from the first day of January, it begins on the second day and lasts through the last day mentioned; in carefully drawn leases the number of days is fixed to avoid all dispute. A lease for a year with the privilege of remaining three years or longer does not mean a single period of three years, but three yearly periods as the tenant may elect.

A lease may be made to take effect in the future, provided the time for taking possession is not so far away as to violate some statute to the contrary. A lease for an hundred years in some states is deemed a parting with the absolute title to lands though railroads make long leases running for ninety-nine years. If the length of the term is not definitely expressed in the lease, the time may be ascertained by other evidence. When a lease is to run for one or more years "from" a specified day, the corresponding day of the year is excluded from the term, unless a contrary custom exists. A lease to a specified day ends with its expiration. If there be a doubt on which of two days a lease terminates, the lessee may decide. More generally, leases of doubtful duration are construed in favor of the tenants. By statute in New York leases which do not specify the length of occupation, extend to the first of the following May after taking possession.

A lease must describe clearly the premises, nor can a defective description be cured by outside evidence. Any language will suffice that shows the intention of the parties. The words "grant," "demise," and "to farm let," have a technical meaning, and are generally used, but other words may be and often are used. A memorandum expressing the consent of the owner that another shall have immediate possession of the premises, and shall continue to occupy them at a specified rent and for a definite term, is a sufficient lease; in general, any agreement under which one person obtains the right of enjoyment to property of another, with his consent and in subordination.

A distinction exists between a lease and an agreement for a lease, which should be understood, though it sometimes is not by the parties themselves. If the agreement is a lease, it cannot be changed by other evidence, for it is a completed contract; but if it is an agreement for a lease, then it is not complete and other evidence may be produced to show what the parties intended. How can the nature of the agreement be tested? By ascertaining whether it is complete or not. Thus A wrote to B that he would take his home at a stipulated rent for two years if he would put in a furnace, with which offer B at once complied.

This was a lease, for by putting in the furnace nothing more remained to be done. If he had not put in the furnace, or not before the time A was to take possession, there would have been no lease, unless A had waived his offer and taken possession.
