What additional requirement does a tenancy by the entirety have compared to joint tenancy?

The requirement for a tenancy by the entirety to be between a husband and wife is a defining characteristic that distinguishes it from joint tenancy. In a joint tenancy, ownership can be held by any number of individuals, regardless of their relationship, and does not mandate that the co-owners be married. In contrast, a tenancy by the entirety specifically limits this type of concurrent ownership to married couples, thereby offering certain legal protections and rights that apply uniquely to spouses, such as the right of survivorship which also exists in joint tenancies.

This marital requirement underscores the unique nature of tenancy by the entirety, as it not only encompasses equal ownership but also reflects the legal notion of unity in marriage, which impacts how the property is treated upon divorce, death, or other legal proceedings. Thus, this aspect adds a layer of protection and cohesion in the management of property owned by married couples.
