Final answer:
The property acquired after marriage by both spouses' efforts is known as community property, which is jointly owned under the community property system.
Step-by-step explanation:
The real property acquired subsequent to marriage by the efforts of both spouses is called community property. This legal concept presumes that property acquired during the marriage is owned jointly by both spouses, regardless of who earned the money to purchase the property. The community property system is recognized in some states, and it contrasts with separate property, which is property owned by one spouse before the marriage or acquired by gift or inheritance during the marriage.
