What is the legal term for a tenant’s right to occupy a rental property?

The legal term that best represents a tenant’s right to occupy a rental property is "Tenancy." This term encompasses the relationship between the landlord and the tenant, delineating the tenant's right to inhabit the space as defined by the rental agreement or lease. Under tenancy, the tenant has certain rights and responsibilities, which often include the right to live in the property, the obligation to pay rent, and adherence to the terms specified in the lease.

Other options don't accurately capture this specific legal right. "Ownership" refers to the rights associated with possessing the title to a property, which does not apply to tenants. "Leasal" is not a standard legal term and seems to be a confusion with "lease," which is the document that may establish tenancy but does not define the right itself. "Possession" can refer to having physical control over the property, but it lacks the specific legal identity that "tenancy" provides, which includes formal recognition of the tenant's right to occupy the property based on a lease agreement.
