The four unities of possession, interest, time, and title are associated with which type of ownership?

The four unities of possession, interest, time, and title are specific concepts associated with joint tenancy. In a joint tenancy, all owners hold an equal share of the property and have equal rights to possess the whole property.

• The unity of possession means that each joint tenant has the right to possess the entire property, not just a specific portion.

• The unity of interest indicates that all joint tenants hold the same type and amount of interest in the property.

• The unity of time requires that all joint tenants acquire their interests at the same time, ensuring equal rights to ownership from the beginning.

• The unity of title states that all joint tenants must hold their interests under the same title or legal instrument.

These four unities create a special relationship among joint tenants, most notably the right of survivorship, whereby if one tenant dies, their interest automatically passes to the surviving joint tenants, rather than being inherited by their heirs. This distinguishes joint tenancy from other forms of ownership, such as tenants in common, where the unities do not apply in the same manner.
