Which characteristic is not applicable to joint tenancy ownership?

Joint tenancy ownership has several defining characteristics, and one of the key elements is that all owners must have equal shares in the property. The right of survivorship allows for the remaining owners to inherit the deceased owner's share, ensuring that the ownership remains with the surviving tenants.

Unity of time is significant as it requires that all joint tenants acquire their ownership interests at the same time. Similarly, unity of title ensures that all tenants hold their interest in the same document or deed. All these elements together support the nature of joint tenancy.

In contrast, a characteristic that does not apply to joint tenancy is unequal share of ownership, as all joint tenants must own the property equally, enhancing the principle of unity within this ownership model. This makes the characteristic of unequal share inconsistent with the very definition of joint tenancy.
