Which of the following best describes a tenancy at sufferance?

A tenancy at sufferance occurs when a tenant legally occupies a property after the expiration of a lease, but without the landlord's consent. In this situation, the tenant continues to use the property without a formal rental agreement or lease extension. This is characterized by the landlord's lack of permission for the tenant to remain, which places the tenant in a precarious legal standing.

The other options describe different tenancy situations; for instance, paying rent under a fixed lease denotes a formal agreement, which does not apply in a tenancy at sufferance. When a tenant has legally vacated the property, they no longer occupy the premises, contradicting the definition of a tenancy at sufferance. Similarly, a lease negotiated for an indefinite period implies an agreement between the landlord and tenant, further distancing it from the concept of a tenancy at sufferance. Thus, the description of a tenant using the property without a formal agreement accurately captures the essence of this type of tenancy.
