Final answer:
The wife would receive a fee simple estate in the event of her husband's death if they owned real estate in joint tenancy. This is due to the right of survivorship associated with joint tenancy, causing the surviving joint tenant to inherit the entire property.
Step-by-step explanation:
If a husband and his wife are the owners of real estate in joint tenancy, the kind of title or estate the wife would receive in the event of the death of her husband is a fee simple estate. Joint tenancy is a form of property ownership that is characterized by the right of survivorship, where the surviving owner automatically inherits the entire property upon the death of the other owner, without the need for probate or a will. Therefore, the correct answer is: b. A fee simple estate.
Under joint tenancy, both parties have equal ownership and the right of survivorship, which means when one joint tenant dies, the surviving joint tenant(s) become the full owners of the property. This differs from a life estate, dower interest, or remainder estate, which are different forms of property interests that do not confer full ownership rights like joint tenancy does.
