Final answer:
Tenancy by the entirety is an estate that is held by husband and wife, where both spouses have equal and indivisible rights to the property.
Step-by-step explanation:
An estate that is held by husband and wife is called tenancy by the entirety. In this type of ownership, both spouses have equal and indivisible rights to the property. This means that neither spouse can sell or transfer their interest in the property without the consent of the other spouse. Tenancy by the entirety is recognized in some states in the United States and provides certain legal protections for married couples.
