What defines a tenancy at will?

A tenancy at will is characterized by its lack of a specified duration, which means that either party – the landlord or the tenant – can terminate the rental agreement at any time, provided adequate notice is given. This arrangement provides flexibility since it doesn't bind either party to a long-term commitment.

In this type of tenancy, the agreement can be established verbally or in writing, but there is typically no formal lease contract that stipulates fixed terms. This distinguishes it from agreements that are bound by specific durations or formalities. Thus, the essence of a tenancy at will lies in its indefinite nature and the freedom it grants both parties to end the tenancy without needing to supply specific reasons or follow legal procedures applicable to more formal leases.
