Which of the following estates requires both spouses to be named on the deed?

The requirement for both spouses to be named on the deed pertains specifically to Tenancy By The Entireties. This form of ownership is unique to married couples, allowing them to hold property together as a single legal entity. This means that both spouses have equal rights to the property and a unified interest in it, which can provide certain legal protections and benefits, such as immunity from creditors of one spouse.

In contrast, other forms of ownership do not have the same stipulation. For instance, Fee Simple Estate can be held by an individual without the necessity of involving a spouse. Joint Tenancy typically allows two or more individuals to own property together with equal shares and includes the right of survivorship, but does not inherently require spousal ownership. Tenancy in Common allows multiple owners to hold shares in the property, but each owner can independently transfer their interest, and it does not require that both names be on the deed.

The unique characteristic of Tenancy By The Entireties reinforces the legal union between spouses, emphasizing the need for both to be named on the deed.
