Community property is a marital property regime under which most property acquired during the marriage (except for gifts or inheritances), the community, or communio bonorum, is owned jointly by both spouses and is divided upon divorce, annulment, or death. Joint ownership is automatically presumed by law in the absence of specific evidence that would point to a contrary conclusion for a particular piece of property.
Division of community property may take place by item by splitting all items or by values. In some jurisdictions, such as California, a 50/50 division of community property is strictly mandated by statute so the focus then shifts to whether particular items are to be classified as community or separate property. In other jurisdictions, such as Texas, a divorce court may decree an "equitable distribution" of community property, which may result in an unequal division of such. In non-community property states property may be divided by equitable distribution. Generally speaking, the property that each partner brings into the marriage or receives by gift, bequest or devise during marriage is called separate property (not community property). See division of property. Division of community debts may not be the same as division of community property. For example, in California, community property is required to be divided "equally" while community debt is required to be divided "equitably".
Property owned by one spouse before the marriage is sometimes referred to as the "separate property" of that spouse, but there are instances in which the community can gain an interest in separate property and even situations in which separate property can be "transmuted" into community property. The rules vary from jurisdiction to jurisdiction.
The community property concept originated in civil law jurisdictions but is now also found in some common law jurisdictions. The states of the United States that recognize community property are primarily in the Western United States; it was inherited from Mexico's ganancial community system, which itself was inherited from Spanish law (a Roman-derived civil law system) and ultimately from the Visigothic Code. While under Spanish rule, Louisiana adopted the ganancial community system of acquests and gains, which replaced the traditional French community of movables and acquests in its civil law system.
