What are the four unities required for a joint tenancy?

The correct choice identifies the four essential unities required to establish a joint tenancy, which are unity of title, unity of time, unity of interest, and unity of possession.

Unity of title means that all joint tenants must acquire their interest through the same legal document or conveyance. Unity of time stipulates that all joint tenants must receive their interests at the same time, ensuring that their interests are synchronized. Unity of interest requires that all joint tenants hold an equal share in the property, reflecting the nature and extent of their ownership. Lastly, unity of possession means that all joint tenants have the right to possess and use the entire property, not just a portion of it.

These four unities work together to create the legal framework for a joint tenancy, ensuring that all parties involved operate under shared rights and responsibilities regarding the property. This structural principle differentiates joint tenancy from other forms of property ownership, such as tenancy in common, where these unities may not apply in the same manner.
