The relation of landlord and tenant may arise between parties by a written agreement or by an oral agreement, but a lease for more than one year is required by statute to be in writing, subscribed by the lessor or landlord.
A tenancy may be either for years, from year to year, monthly, or at will or sufferance. An estate for years is created by writing and arises in all cases where formal leases are entered into. Estates from year to year may arise by operation of law, as where a tenant for years holds over at the end of a year, or where a tenant enters into the possession of the property for a term under a parol lease which is void under the Statute of Frauds. An estate at will is one which is terminable by either party, and an estate at sufferance arises where a tenant holds over and the holding over has not existed long enough to make a continuance under the preceding lease.
