A tenancy at will is leasehold right. This means that either a landlord or a tenant can terminate the tenancy at any time by giving a reasonable notice. This situation arises when there is no lease agreement or when the tenancy is not for consideration.
The tenant holds right over the property with the permission of the landlord for an unspecified period. People who want to end their occupation of a premise only for a short period usually depend on tenancy at will. By this method a tenant can end property occupation without going through any legal measures.
A tenancy at will can be terminated by operation of law when a tenant commits waste in the property, when a tenant attempts to assign his/her tenancy, when a landlord transfers his/her interest in the property, when a landlord leases the property to another for a specified period for rent, and when the tenant or landlord dies.
